limitation, to a system and method for providing information such
as advertising to a consumer as a shopping cart is navigated within
a store.
BACKGROUND OF THE INVENTION
[0002] In today's media market, measuring efficacy of advertising
is difficult. Advertisers are spending billions of dollars on
television, radio, and print with little return on investment, and
they have little assurance that consumers will actually see
advertisements, much less make purchasing decisions impacted by
them. Thus, advertisers and stores are constantly searching for new
and related advertising venues, and in particular those positioned
at, or in close proximity to, the point of purchase location. To
wit, the traditional shopping cart is an underutilized advertising
medium. The shopping cart is the one venue that continually moves
with the consumer as they navigate the store. Thus, the shopping
cart provides an advertising venue with opportunity to improve the
shopping experience of the consumer.
[0003] The present disclosure is aimed to address needs of
advertisers, retailers, and consumers. Advertisers wish to 1)
display ads at the most effective location and time, at the
consumer's point of purchase, 2) specifically measure the
effectiveness of advertising campaigns, and 3) improve return on
advertisement investment dollars. Retailers wish to 1) increase
sales, 2) share in advertising revenue, 3) reduce labor costs, 4)
create a consumer friendly environment with less advertisement
clutter, 5) enhance their store image and 6) make improvements that
are compatible with existing solutions. Consumers wish to 1) have a
pleasant and efficient shopping experience, and 2) save money on
items that they need or want.
SUMMARY OF THE INVENTION
[0004] According to one embodiment, a media enhanced shopping cart
system is provided. The media enhanced shopping cart system
comprises a shopping cart comprising a frame, a basket, a handle, a
base tray, a plurality of wheels, a read component for performing a
proximity scan of the shopping cart, a locationing component for
determining a location of the shopping cart within a store based on
the scan, and a display component for displaying at least one
advertisement for a product based on the location of the shopping
cart within the store, wherein the locationing component is further
operable to determine a location of the product within the store
relative to the shopping cart based on the scan, and wherein the
display component is further operable to display an indication of
the location of the advertised product relative to the location of
the shopping cart.
[0005] In another embodiment, a method is provided. The method
comprises performing a proximity scan from a shopping cart,
determining a location of the cart within a store based on the
scan; displaying at least one product advertisement based on the
location of the cart, correlating a location of an advertised
product with the location of the cart, and displaying an indication
of the location of the advertised product with respect to the
location of the shopping cart.

an embodiment, the ECM 200 may incorporate the following types of
programming: an embedded database engine, a business object layer,
a graphic user interface presentation layer (GUI), one or more
media display engines, automatic speech recognition engine, a bar
code device driver, and an RFID reader driver.
[0062] The Cart Coordinator is an application running on the ECM
200 of the cart 10 that is responsible for keeping the cart's 10
electronic functionalities up-to-date, including all the content
(such as advertising) as well as the software (i.e. applications
and operating system). One of the many functions of the Cart
Coordinator is to allow the cart 10 to communicate with a store's
in-store server ("ISS") 330. In various embodiments, the Cart
Coordinator performs some or all of the functionality while the
cart 10 is in the cart corral 110. The Cart Coordinator also
maintains communication with the ISS 330 while the cart 10 is out
of the cart corral 110, e.g. during a shopping session. The Cart
Coordinator checks the status and version of content and software,
and upon finding an item (i.e. content or a piece of software) that
needs to be updated, the Cart Coordinator starts a download via the
wireless connection.
[0063] The Deployment Manager is another application running on the
ECM 200 of the cart 10 that is responsible for installing the
software downloaded by the Cart Coordinator on the cart 10. The
Deployment Manager includes the ability to determine whether a
change is a minor change such that a simple update may be
installed, or a more significant change requiring installation and
restart, or a major change, calling for installation of the
software followed by rebooting the cart 10.
[0064] In various embodiments, the Cart Coordinator and the
Deployment Manager are functional for synchronizing and updating
only when the cart 10 is present in the corral 110, while in other
embodiments, the Cart Coordinator and the Deployment Manager are
functional for synchronizing and updating while the cart 10 is not
in use but not necessarily present in the corral 110.
[0065] In various embodiments, the Deployment Manager functions
when the cart 10 is located in the cart corral 110, because it is
desirable to make major changes to the cart when the cart 10 is
located within the best network coverage, which in some embodiments
may be in the cart corral 110. Additionally, it is undesirable to
encumber the cart's 10 assets by downloading while the cart is in
use for shopping. Furthermore, the cart 10 has unlimited power when
located in the corral 110, making the corral 110 the preferable
location for synchronizing because synchronizing uses a significant
amount of power.
[0066] In various embodiments, the Cart Coordinator is additionally
responsible for uploads from the cart 10 to the ISS 330. For
example, shop events such as time spent with a certain ad
displayed, the path of the cart 10, items purchased, and the like
may be scheduled for upload from the cart 10 to the ISS 330 by the
Cart Coordinator.
[0067] In various embodiments, the Cart Coordinator may
additionally provide periodic real time updates for items such as
new product prices, store specials, and the like that are displayed
and/or used by the cart 10.
[0068] In an embodiment, the ECM 200 may enter a hibernation or
sleep mode when the cart 10 is nested with one or more other cart
10, when the cart 10 is stored, or when the cart 10 is not in
motion for a predetermined period of time. In an embodiment, the
hibernation or sleep mode may involve powering the ECM 200 down
entirely, or partially. In an embodiment, the cart 10 may further
comprise one or more motion sensors 36 operable to detect when the
cart 10 is in motion. The motion sensor(s) 36 may be located
anywhere on the cart 10. The motion sensor(s) 36 may be located in
or on the handle 22 (for example in pod 150) as shown in FIG. 3A,
the base 35, or the base tray 50. Alternatively, the motion
sensor(s) 36 may be coupled to wheels 37, 38 and detect motion of
the cart from turning of one or more wheels. Alternatively, the
motion sensor(s) 36 may be integrated with a scanner 215, wherein
the motion sensor may serve as a proximity sensor 216 for the
scanner and/or a proximity sensor 216 for the scanner may serve as
a motion sensor for activating components of the cart.
Alternatively, the motion sensors(s) may be located in the ECM 200,
for example a mercury switch or equivalent that detects movement of
the cart. The motion sensor(s) activate the ECM 200, bringing it
out of hibernation, when the cart 10 is selected by a consumer 85
from a nested position with one or more other carts, from a cart
corral 110, or when a consumer 85 begins to move an abandoned cart
10 that has not moved for a predetermined length of time. Each of
the components operably coupled to or comprising components of the
ECM 200, as described below, may also be re-activated or hibernated
along with the ECM 200 when the motion sensor(s) 36 detects that
the cart 10 is in motion.
[0069] In an embodiment, the motion sensor(s) 36 may comprise
mercury switches placed on the cart 10, such as in a location on a
wheel 38 or caster, or on the basket 20 of the cart 10, such that
when the cart 10 is in motion, the mercury in the switch tilts with
the motion of the cart 10 to connect and disconnect the control of
the ECM 200 or the various other components.
[0070] In still another embodiment, the motion sensor(s) 36 may
comprise one or more magnetic reed switches in addition to or in
lieu of mercury switches. In such an embodiment as shown in FIG.
3B, a magnetic reed switch 180 is located in the frame or caster
182 above each wheel 38, and an associated magnet 184 is located on
the wheel 38 hub, allowing sensing of tire rotation about axle 183
for motion detection. As is well understood in the art, by placing
a magnet on a rotating wheel, a "heartbeat" reflecting the
rotational speed of the wheel may be determined, with one "beat"
each time the magnet rotates past the reed switch, opening or
closing it. By placing a pair of these switch and magnet groupings,
one at each wheel, the ECM 200 may receive a signal from the
magnetic reed switch via cable or wire 181 running through frame 30
and determine the rotation speed of each wheel when in motion. By
comparing rotational speed of adjacent wheels (for example, the two
back wheels having a fixed, known position relative to each other),
the ECM 200 may additionally determine when the cart turns as well
as the speed and direction of turns, providing additional data for
use in accurate determination of the location of the cart within
the store. Further discussion of the use of magnetic reed switches
in locating the cart 10 within the store is included below.
[0071] In an embodiment, the shopping cart system further comprises
a correlation component comprising software, hardware or a
combination of hardware and software operable to take various data
gathered by components of the cart, and correlate one or more of
the different types of data. The correlation component may, in an
embodiment comprise hardware affixed to the cart with software
incorporated therein, or may, in an embodiment, comprise hardware
affixed to the cart with software stored in and/or executed from
the ECM 200. In an embodiment, the correlation component may be
integrated within the ECM 200.
[0072] For example, the correlation component is operable to
correlate data from the inventory component (discussed in greater
detail below) regarding the inventory contained by the shopping
cart, with the unique identity of the shopping cart. In such an
exemplary embodiment, the correlation component is operably coupled
to the inventory component and the ECM 200, such that as the
inventory of the cart 10 is updated, the correlation component
correlates the current inventory with the unique identity of the
cart 10 and stores the correlation (preferably in the ECM 200),
such that, at the Point of Sale 300, the ECM 200 may wirelessly
communicate the correlation of the inventory and the unique
identity of the cart 10. The correlation component may be further
operably coupled to the locationing component, such that the
correlation component may correlate the inventory, the unique
identity, and the location of the cart, over the course of a
shopping trip, store the correlation, and wirelessly communicate
the correlation to the Point of Sale 300.
[0073] For example, the correlation component is operable to
correlate data from the inventory component (discussed in greater
detail below) regarding the inventory contained by the shopping
cart, with data relating to the shopping list component (discussed
below). In such an exemplary embodiment, the correlation component
is operably coupled to the inventory component, the shopping list
component, the ECM 200, and the video display 75, such that as the
inventory of the cart 10 is updated, the customer shopping list may
be updated, as well as the shopping list displayed in the video
display 75. The correlation may be stored in the ECM 200, or stored
elsewhere in the network associated with a specific consumer, and
used to generate shopping lists in the future.
[0074] For example, the correlation component is operable to
correlate data from the inventory component (discussed in greater
detail below) regarding the inventory contained by the shopping
cart, with data relating to which advertisements are displayed to a
consumer by the cart. In such an exemplary embodiment, the
correlation component is operably coupled to the locationing
component, the video display 75 and the ECM 200, such that the
correlation component receives the inventory from the inventory
component, correlates it with advertisements that are stored or
streamed to the ECM 200, and stores the correlation. The
correlation may then be used in selecting which advertisement
chosen from a plurality of advertisements are displayed based on
the location of the cart. For example, if the inventory is known to
include items for hosting a party, the correlation of the inventory
with the advertisements and the location of the cart may be used to
display one or more advertisements for additional items used for
hosting a party.
[0075] The shopping cart system may further comprise a shopping
list component for listing one or more products of a customer
shopping list for purchase by the consumer. The shopping list
component is operably coupled to the video display 75 of the cart
10 such that the shopping list may be displayed, either
prominently, or as a less prominent display, with, for example, a
menu of options or advertisements. In an embodiment, the shopping
list component may comprise hardware, software, or a combination of
hardware and software operable to carry out the function of
maintaining, updating, and/or displaying a customer shopping list.
In an embodiment, the hardware and software are co-housed and
affixed to the cart 10, while in another embodiment, the hardware
may comprise a unit affixed to the cart 10 (as will be discussed
below) and the software may be stored and/or executed from a
separate unit, such as the ECM 200, the ISS 330, POS computer 326
at the Point of Sale 300 or other networked system component, in
conjunction with the hardware affixed to the cart.
[0076] In an embodiment, the shopping list component comprises the
ECM 200 in conjunction with software operating thereon, populated
with a customer shopping list. In an embodiment, the customer
shopping list comprises historical data associated with the
consumer 85 by way of the consumer's loyalty card, pin code,
telephone number or other customer identifier associated with the
consumer 85. The historical data relates to products that the
consumer has purchased in the past or products that the consumer
has listed in a customer shopping list previously. Consumer
identifiers comprise a data reference that is unique to the
consumer or their household. For example, a customer loyalty card
may be associated with an identification number that is unique to
the consumer or their household. Stores often offer customer
loyalty cards to consumers, which consumers use in order to enjoy
coupons, discounts and other advantages provided by the store to
its loyal consumers. The loyalty card may additionally be linked
with store services, such as a pharmacy, in-store deli, automotive
service station, and the like, to track and record the consumer's
needs relating to that service. A consumer may additionally
identify themselves to the store using a pin code assigned by the
store or their telephone number in order to receive discounts,
coupons, and track usage of the store's services. The store may use
the identifiers to track shopping of consumers for inventorying
purposes as well as targeting advertisements and discounts to
consumers based on what they actually buy.
[0077] In an embodiment, the customer shopping list for future
shopping trips is generated by the inventory in the cart 10 during
a present shopping trip. In such an exemplary embodiment, the
shopping list component is operably coupled to the inventory
component and the ECM 200 (or other networked component) to store
the inventory of the cart 10 during a shopping trip, and store the
purchases made based on the inventory at the Point of Sale 300. In
such an embodiment, the stored inventory may be associated with a
particular consumer by way of their customer loyalty card, pin
code, telephone number or other consumer identifier. The stored
inventory may then be used by the shopping list component to
generate a customer shopping list.
[0078] In an embodiment, the customer shopping list may be
downloaded from a store website and associated with the consumer's
identity, such that when the loyalty card is scanned or other
identifier is entered, the customer shopping list becomes available
in the cart 10 to the consumer 85. In such an embodiment, when the
consumer identifier is entered or scanned, the list downloaded from
the store website may be streamed or wireless communicated from the
ISS 330 via the access points to the ECM 200, and displayed.
Alternatively, in an embodiment a shopping list stored in a PDA,
handheld computer, mobile telephone or other electronic device may
be downloaded to the ECM 200 through wireless, infrared, Bluetooth,
and like known techniques, the details of which are not material
herein, and the shopping list component will display the downloaded
list, and enable the functions described herein. Alternatively, in
an embodiment a shopping list may be emailed to the store system
for transfer to a cart 10.
[0079] In still another embodiment, the customer shopping list is
generated based one or more products selected by the consumer;
wherein the one or more products are selected by the consumer by
scanning a bar code on a product, placing a RFID tagged product in
the shopping cart 10, and downloaded by the consumer in a list. In
such an embodiment, the ECM 200 is operably coupled to the
inventory component to store the identity of products purchased by
the consumer before to generate a list. In such an embodiment, the
ECM 200 is operable to store the identity of products previously
placed in the cart 10 by the consumer to generate a list.
[0080] In an embodiment, the shopping list component is operably
coupled to the correlation component in conjunction with the ECM
200 (as discussed above) for correlating the inventory contained by
the shopping cart 10 with the shopping list to determine which
products on the list are present in the shopping cart 10.
[0081] In an embodiment, the shopping list component is operably
coupled to the ECM 200, the locationing component and the video
display 75 for displaying an advertisement on the video display 75
for a product on the shopping list when the cart 10 is located
proximate to the product. In such an exemplary embodiment, the
locationing component determines where the cart is located in the
store, the shopping list component determines which products on the
customer shopping list are located nearby the cart based on its
location, and the ECM 200 displays in the video display 75 at least
one advertisement based on the cart 10 being located near to
products on the shopping list.
[0082] In use, in an embodiment, the customer shopping list may be
displayed in the video display 75 as a less prominent display with
advertisements, or as a prominent display when selected by a
consumer. By prominence, it is meant that the shopping list may be
displayed as a larger, primary display on the video display 75
while advertisements are displayed in smaller, secondary display(s)
on the video display 75 adjacent to the shopping list. As will be
described further below, and as shown in FIG. 16, in an embodiment,
the screen 77 of the video display 75 may be divided into a
plurality of screen segments 308, such that one of the plurality of
stored advertisements 307 may be displayed in various screen
segment 308 while a shopping list may be displayed in a screen
segment 308. In an embodiment, one of the plurality of screen
segments 308 may be designated for display of consumer specific
information, such as the customer shopping list.
[0083] The shopping list component may organize the products on the
customer shopping list with locations in the store for each product
on the list, and display the customer shopping list according to
location. For example, the shopping list component may organize all
the products on the customer shopping list according to a
department of the store, or according to which aisle the products
are located on, in order to facilitate shopping by the
consumer.
[0084] In use, in an embodiment, the shopping list component,
coupled to the correlation component, correlates the customer
shopping list to the inventory of the cart 10, such that when a
RFID tagged product from the customer shopping list is scanned by
the basket RFID reader 227 or scanned by the scanner 215, the
product is checked off the customer shopping list. In an
embodiment, the consumer may check off a product from the customer
shopping list. In the video display, the product may appear as
checked off, or may be removed from the shopping list once added to
the inventory of the cart.
[0085] In use, in an embodiment, the selection of advertisements
displayed to the consumer may be correlated to the customer
shopping list by the shopping list component, the correlation
component (as discussed herein) and the ECM 200 or other networked
component.
[0086] In an embodiment, the shopping list component is further
operable, in conjunction with the ECM 200 or other networked
component, for a consumer to select a recipe, and generate a
customer shopping list based on the ingredients used for preparing
the recipe. In such an embodiment, the consumer may select a recipe
(either stored in the ECM 200, or streamed to the cart 10), and the
ingredients necessary for preparing the recipe (also either stored
in the ECM 200, or streamed to the cart 10) are added by the
shopping list component to the customer shopping list.
[0087] In embodiment, the shopping cart system further comprises a
voice activated interface 120. In an embodiment, a voice activated
interface 120 comprising a microphone array 121 and a voice

microphone array 120. In an embodiment, the voice activation button
122 may comprise a button of a five-way navigation device 123 or
other navigation device and the microphone(s) may be housed in the
pod 150. By pressing the voice activation button 122, the consumer
85 may activate a voice command option, enabling the consumer 85 to
request the cart 10 to display the location of a particular product
or other detailed information from a list of options on the video
display 75. In an embodiment, the microphone array 120 has built-in
noise cancellation capabilities.
[0088] In an embodiment, the voice activated interface 120,
microphone array 121 and voice activation button 122 are operably
coupled to the ECM 200. In an embodiment, the ECM 200 may store
voice recognition software operable to process a spoken input from
the consumer 85 through the microphone array 121 upon activation of
the voice command option. The ECM 200 may determine an answer to
the spoken question (which may involve reference to a database of
product information) and display the answer on the video display
75. The answer may be provided graphically or in written
description form, and may include a location (e.g., map) or a menu
of options 124. For example, referring to FIG. 5, an exemplary
response to a spoken input is shown. Upon a request by a consumer
85 being picked up by the microphone array 121, the video display
75 may identify the product requested (i.e. "ACME cottage cheese"),
and display a written description 125 of the location of the
product requested, as well as a graphical display 126 of a map of
the store indicating the location 127 of the product requested with
indication of the current location 128 of the cart. The video
display 75 may simultaneously display a list of other options 124,
e.g., a list of available voice commands, as well as one or more
advertisements 306 in the plurality of screen segments 308, wherein
the advertisements 306 are selected from a plurality of stored
advertisements, as will be described in greater detail herein.
[0089] In an embodiment, the voice recognition software may
comprise VoCon 3200.TM. software, commercially available from
SCANSOFT.TM. or an equivalent software having similar voice
recognition capabilities. In an embodiment, the voice activated
interface 120, operably coupled to the ECM 200, may be re-activated
from hibernation along with the ECM 200 when the motion sensor(s)
36 detects that the cart 10 is in motion.
[0090] In embodiment, the shopping cart system further comprises a

[0091] In an embodiment, the speaker may be operable to play audio
portions of advertising corresponding to advertisements displayed
on the video display 75. In an embodiment, the speaker may be
operable to make announcements, such as a store announcement, or
annunciate a successful scan, by audibly alerting the consumer when
a product is scanned by the scanner 215 or when a RFID tagged
product is added to the cart 10. In an embodiment, the speaker
enables a customer service representative to speak with a consumer
using the cart, resulting in saving the consumer from having to go
stand in line at a customer service counter. In an embodiment, the
speaker enables a store employee to speak with a consumer using the
cart to alert the consumer to the status of their order at an
in-store service such as a deli, pharmacy or automotive center.
[0092] In an embodiment, the shopping cart system may further
comprise an inventory component for determining an inventory
contained by the cart 10. The inventory component is operable to
take an inventory of products placed in the basket 20 or products
placed on the base tray 50. The inventory component may, in an
embodiment, be operable to determine the inventory automatically
without any action on the part of the consumer beyond placing a
product in the cart 10. Alternatively, the inventory component may,
in an embodiment, rely on some action by the consumer in order to
determine the inventory of the cart 10, such as determining the
inventory of the cart 10 when the consumer scans a product and
places the product in the cart 10.
[0093] In an embodiment, the inventory component comprises hardware
and software operable to carry out the inventorying function. In an
embodiment, the hardware and software are co-housed and affixed to
the cart 10, while in another embodiment, the hardware may comprise
a unit affixed to the cart 10 (as will be discussed below) and the

may use any suitable wired or wireless communications protocol such
as those described herein.
[0094] In use, in an embodiment, the inventory component, in
conjunction with the ECM 200 and the correlation component, is
operable (as discussed above) to determine the inventory contained
by a shopping cart, correlate the inventory to the unique identity
of the shopping cart, convey the unique identity of the shopping
cart to a Point of Sale 300 (or other retailer system), and convey
the inventory of the shopping cart to a Point of Sale 300 (or other
retailer system).
[0095] In use, in an embodiment, the inventory component is
operably coupled to the ECM 200 and the identification component
(discussed in greater detail herein). The identification component
associates a unique identity with a shopping cart and the inventory
component determines an inventory of the shopping cart. The
correlation component (discussed in greater detail herein)
correlates the inventory to the unique identity of the shopping
cart, and the ECM 200 conveys the inventory of the shopping cart,
or the correlation of the inventory to the unique identity to a
retailer system, or the identification component conveys the unique
identity of the shopping cart, or any combination thereof.
[0096] In use, in an embodiment, the inventory component determines
an inventory contained by the cart 10. The inventory component is
operable coupled to the shopping list component, the correlation
component (both discussed in greater detail herein), the ECM 200
and the video display 75. The inventory component determines the
inventory contained by a shopping cart, the shopping list component
displays on the video display 75 a customer shopping list, the
shopping list comprising one or more products for purchase. The
correlation component correlates the inventory contained by the
shopping cart with the shopping list to determine which products on
the list are present in the shopping cart; and convey the inventory
and the shopping list to a Point of Sale 300 at the time of
purchase. Preferably, conveying the inventory and shopping list to
the Point of Sale 300 is done wirelessly by the ECM 200, for
example via any suitable wireless protocol such as those described
herein.
[0097] In an exemplary embodiment, the inventory component may
comprise at least one basket RFID reader 227 with one or more RFID
antennas 228 in conjunction with the ECM 200 and software operating

as shown in FIG. 13; the side walls 23, 24; front side wall 28;
rear side wall 31, or combinations thereof on basket 20 and/or base
tray 50.
[0098] As products are placed in the basket 20 and/or base tray 50,
and identification information (including, in an embodiment, the
product EPC described above) is provided to the ECM 200, which may
be further correlated with additional information such as price,
product information, advertising, etc. In an embodiment,
information may further be displayed on the video display 75, for
example information pertaining to the product placed in the basket,
added to a running total of the products in the cart 10, etc. The
basket RFID reader 227 with RFID antennas 228 may automatically
detect when an product has been removed from the cart 10 and placed
back on a shelf, and will convey to the ECM 200 that the product
has been removed, thus deducting the removed product from the
running total displayed on the video display 75. The network
transceiver 204 may additionally convey information about a product
placed in or removed from the cart 10 to various network components
as will be described in greater detail herein. In an embodiment,
the cart 10 is a plastic cart as described herein which lessens or
eliminates interference associated with basket RFID reader 227 and
RFID antennas 228. In an embodiment, the cart 10 is a cart
comprising metal, plastic, or a combination of plastic and metal
that is retrofitted with the media enhancements described here.
[0099] In another exemplary embodiment, the inventory component
alternatively or additionally comprises a scanner 215, for example
a bar code scanner. In an embodiment, the scanner 215 is inset in
the handle 22 and/or in pod 150 of the cart 10. In an embodiment,
the scanner 215 may be attached to or incorporated with any portion
of the basket 20, such as the side wall 23 or 24, the front side
wall 28 or the rear side wall 31, in a manner that is accessible to
the consumer 85 who is using the cart 10. Various attachment
devices and means for attaching as described herein may be used
with the scanner 215. The scanner 215 enables optional
self-scanning of products for purchase, coupons, loyalty cards, and
any other object having a bar code or Universal Product Code
("UPC") by the consumer 85. In an embodiment, the scanner 215 may
be activated by the consumer 85 by bringing any product with a
barcode symbol within a set proximity of the scanner 215. In an
embodiment, the scanner 215 may be activated by a proximity sensor
216, which may comprise a portion of the scanner 215 or may be
operably coupled to the scanner 215. Like the scanner 215, the
proximity sensor 216 may likewise be integrated with pod 150. The
scanner 215 may be any suitable scanner such as a laser scanner,
CCD scanner, 2D imager, and the like. In an embodiment, the scanner
215 may comprise a linear imager scanner commercially available
from HAND HELD PRODUCTS.TM. or an equivalent or improvement
thereof. The scanner 215 may, in an embodiment, scan symbols, such
as a UPC or European Article Numbering ("EAN") System codes, in an
omni-directional manner.
[0100] In an embodiment, the inventory component may comprise the
scanner 215, in conjunction with the ECM 200 and software operating
thereon. In an embodiment, the inventory component is operable to
determine the contents of the shopping cart based on what products
the consumer 85 has scanned and placed in the shopping cart. In an
embodiment, the scanner 215 is operably coupled to the ECM 200,
such that as products are scanned and placed in the cart 10, the
ECM 200 stores in local memory 202 a running total of the products
in the cart 10 for purchase. Upon arriving at the checkout counter,
known as the Point of Sale 300, the ECM 200 may communicate
information regarding the products that were scanned by the
consumer 85 to a POS computer 326 at the Point of Sale 300 or other
networked system component, to be discussed in greater detail
herein.
[0101] In an embodiment, the scanner 215, operably coupled to the
ECM 200, may be hibernated or re-activated from hibernation along
with the ECM 200 when the motion sensor(s) 36 detects that the cart
10 is in motion or stopped. Specifically, in an embodiment, the
scanner 215 may be hibernated, or powered down, for power
conservation purposes, when the cart 10 is in motion. When the
consumer 85 stops pushing the cart 10 and the cart 10 becomes still
while the consumer 85 is selecting products to purchase, the
scanner 215 is re-activated such that the consumer 85 may scan
products for purchase and place them in the cart 10. The motion
sensor(s) 36 alone or in combination with other locator or
positioning systems/data (for example, RFID scans and/or other
locator/positioning means) enable this hibernation/reactivation
function of the scanner 215. In alternative embodiments, other cart
systems may be activated or deactivated based upon detection of
motion or stoppage of the cart in order to conserve power and
maximize battery life. For example, the bar code reader may be
turned off when the cart is moving, the RFID reader/antennae may be
turned off when the cart is stopped, the video display may be
turned off when the cart is nested or is immobile for an extended
time, or combinations thereof. Again, motion of the cart may be
detected for example via a motion sensor such as a reed switch
and/or mercury switch alone or in combination with other sensing
means such interpreting read data from the RFID tags.
[0102] In an embodiment, the shopping cart system may further
comprise a navigation device, for example a five-way navigation
device 123. In alternative embodiments, other navigation devices
may be used in addition to or in lieu of the five-way navigation
device 123, for example hard or soft hot buttons, a joystick, touch
panel/screen, or combinations thereof. As an additional user
interface to the ECM 200 and other features of the cart 10, in an
embodiment, a five-way navigation device 123 may be inset in the
handle 22 or in the pod 150. The five-way navigation device 123
typically allows for input (e.g., navigation of a menu) via up,
down, left, right, and enter functions. In an embodiment, the
five-way navigation device 123 may be used to activate the
microphone array 121 for voice recognition features, or may be used
to navigate through a menu of options 124 shown on the video
display 75. In an embodiment, the menu of options 124 may comprise
such selections as: 1) a "Help" option, enabling the consumer 85 to
request the location of a particular product, 2) an interface with
an in-store pharmacy for the consumer 85 to request the status of
their prescription or receive notification of prescription
availability, 3) an interface with an in-store deli for the
consumer 85 to make a deli order or receive notification of order
availability, 3) an interface for notification to the consumer 85
of completion of in-store auto servicing, 4) an interface for
interaction between the consumer 85 and customer service personnel
for services such as rain checks, and other functions for in-store
services.
[0103] In an embodiment, the shopping cart system may further
comprise theft and tamper deterrence design features. The shopping
cart, due to the nature of the electronic components used as well
as the programming in the computer, may be targeted for theft and
tampering. To this end, the various electronics assemblies for the
components discussed herein are designed such that if a given cart
is disassembled without customized tools and/or in an improper
sequence of disassembly, the electronics assemblies are rendered
non-functional by virtue of damage incurred by improper
disassembly.
[0104] For example, the main logic board of the ECM 200 may be
designed having the printed circuit board traces laid out with
critical circuit traces residing in close proximity to mounting
holes, such as within a few thousands of an inch from the mounting
hole. The logic board then would be mounted to the casing and ECM
200 frame using a screw with a customized head, thereby requiring a
customized tool for putting in or removing the screw. If the board
is subsequently forced from the casing by someone lacking the
customized tool, the critical traces would be damaged, and the
board would be non-functional to a degree beyond repair without
design schematics for the printed circuit board.
[0105] In another example, the video display 75, which is described
in more detail below and that may comprise a liquid crystal display
("LCD"), includes theft deterrence and tampering design features.
The video display 75 may include two primary physical elements,
namely the LCD display screen and the LCD controller board that
interfaces the LCD display screen via a flex circuit. The flex
circuit connections to the LCD display screen are fragile and will
not withstand flexing or pulling. A thin, insulating metal
retaining bar may be added that runs the length of the flex circuit
between the LCD display screen and the LCD controller board, and
secured in place by a screw or screws with a customized head,
thereby requiring a customized tool for removal. If the metal
retaining bar is not removed using the appropriate customized tool
and in a particular sequence that avoids flexing or pulling the
flex circuit connections, the LCD assembly would be rendered
non-functional to a degree beyond repair.
[0106] In an embodiment, the cart further comprises a battery 135
operably coupled to the ECM 200, the video display 75, voice
activated interface 120, the bar code scanner 215, and any other
component of the cart requiring power. In an embodiment, the
battery 135 is a standard Lithium-Ion battery or other similar
battery. In an embodiment, the battery 135 may be attached to the
underside of the cart 10, by means of attachment to, for example,
the bottom 21 of the basket 20, or to the base tray 50. Various
attachment devices and means for attaching as described herein may
be used with the battery 135. In an embodiment, the battery 135 may
be integrated with the ECM 200. For example, a battery housing or
compartment may be integrally molded from plastic with the ECM 200
housing 199 such that the battery is part of the ECM 200. In an
embodiment, the battery 135 is rechargeable.
[0107] Referring to FIGS. 6, 7, and 8, in an embodiment, the cart
10 may further comprise one or more battery charger contact plates
105. FIG. 6 is a front view of a cart 10 recharging in a recharge
stall 111. In an embodiment, the battery charger contact plate 105
may be located on the base side member 32 and/or 33, the side
member 16 and/or 17, or the side wall 23 and/or 24. For example, as
shown in FIGS. 1 and 6, a single battery charger contact plate 105
may be disposed on each side of cart 10, thereby providing a pair
of battery charger contact plates for each cart. In an embodiment,
the battery charger contact plates may be positioned adjacent the
rear wheels 38, for example on the base side members 32, 33
slightly above the real wheel mount. Given that the rear wheel span
is typically about the widest part of the cart, as can be seen in
FIG. 6, positioning of the battery charger contact plates near the
rear wheels places them in a low, outboard position on the cart
that is useful in engaging a charge rail system 106 for recharging
the battery. In an embodiment, the battery charger contact plate
105 may be spring-loaded to aid in contacting the contact plate
with a charge rail.
[0108] FIG. 8A is a side view of charge rail system 106 for
recharging the battery 135 of one or more carts 10. The charge rail
system 106 comprises a cart corral 110 having a plurality of
recharge stalls or lanes 111, with each recharge lane having charge
rails 107 and 108. In an embodiment, the recharge stalls 111
comprise a plurality of charge rail segments 109. In a store, the
plurality of charge rail segments 109 comprised of charge rails 107
and 108 may be arranged in a cart corral 110. The plurality of
charge rail segments 109 may be arranged in one or more rows of
recharge stalls 111.
[0109] FIG. 8B is a side view of two charge rail segments 109
forming a single recharge stall 111. Each charge rail segment 109
comprises a floor section 113, a charge rail wall 114, and
optionally a stall wall 115, which may be transparent as shown in
the Figures or may be non-transparent. Charge rails 107, 108 are
disposed on either side of charge rail wall 114, as is shown more
clearly in FIG. 6. In an embodiment, a plurality of charge rail
segments 109 may attach together in an end-to-end fashion (as
indicated by reference arrows 116) or in a side-to-side fashion (as
indicated by reference arrows 117) to form the recharge stalls 111
and cart corral 110. As shown in FIG. 8B, the side edge 118 of the
floor section 113 may be configured to mate or interlock with the
side edge 119 of charge rail wall 114 of an adjacent charge rail
segment 109. Likewise, front and rear edges 129, 130 of the floor
section 113 may configured to mate or interlock with corresponding
front and rear edges from adjacent charge rail segments 109.
[0110] In an embodiment, the charge rail system 106 further
comprises a power supply 112 which may be mounted on a wall or
other permanent fixture for providing power to the carts 10. The
power supply 112 may be plugged in and operably connected to the
charge rails 107 and 108. Likewise, the plurality of charge rail
segments further comprise connections such that power is supplied
to the entire cart corral grid via the connection of adjacent
charge rail segments 109.
[0111] In operation, a cart 10 may be fed into a cart corral 110 by
a consumer 85 or store employee placing it in a recharge stall 111.
In an embodiment, the recharge stall 111 may be sized such that the
charge rail segments 109 are spaced apart adequately (e.g., about
equal to the rear wheel span of the cart 10) such that the cart 10
fits between the charge rail segments 109 securely enough for the
battery charger contact plate 105 to come into contact with the
charge rails 107 and 108, as shown in FIG. 7. Contact between a
battery charger contact plates and charge rails 107 and 108 forms a
flow path for electrical current between power source 112 and the
battery 135 such that the battery is charged. Rechargeable
batteries are well known in the art, as are methods of charging
such rechargeable batteries from a power source. In an embodiment,
a first contact plate 105 and a first charge rail (e.g., 107 or
108) form a positive terminal of the electrical connection and a
second contact plate 105 and a second charge rail (e.g., 107 or
108) form a negative terminal of the electrical connection. While
dual contact plates and charge rails are shown, the charge rail
system may be configured to operate using a single contact plate
105 on the cart and/or a single charge rail 107 or 108.
[0112] In an embodiment, each charge rail 107 or 108 may be spring
loaded, each battery charger contact plate 105 may be spring
loaded, or both may be spring loaded. In an embodiment shown in
FIG. 7, the charge rail 107 further comprises a spring 140 biasing
a rail plate 141 outward for contact with the battery charger
contact plate 105 located on the cart. The rail plate 141 may be
surrounded by rail guard 142. The rail guard 142 may be configured
to allow contact between the contract plate 105 and the rail plate
141 while preventing unwanted contact with rail plate 141 which
might lead to electrical shock. In an embodiment shown in FIG. 7,
the rail guard 142 has a concave shape with the rail plate 141
extending outward a portion of depth of the concave cavity, but not
beyond the outer edges 144 of the rail guard 142. The contact plate
105 may have a corresponding convex shape, thereby allowing contact
between the contact plate 105 and the rail plate 141. When a cart
10 is fed into a recharge stall 111, the cooperative shapes and
spring loaded nature of the battery charger contact plate 105
and/or the charge rail 107 or 108 cause them to be in contact with
each other, creating an electrical conductor between the battery
135 and the power source 112. While FIG. 7 is shown with a single
charge rail 108 (for example, for use as an end rail assembly for
attachment on end 118 of FIG. 8B to form a complete stall 111), it
should be understood that typically two charge rails 107 and 108
will be used in a back-to-back or mirror configuration, as is shown
in FIG. 6. The components of the two charge rails 107 and 108 will
be similar to the components shown in FIG. 7 for charge rail
108.
[0113] In an embodiment, the plurality of charge rail segments 109
are further configured to form a cart corral 110 such that a
plurality of carts may be nested and stored therein, and each of
the plurality of carts may be charged at the same time by the
contact between each battery charge contact plate 105 of each cart
with the charge rails 107 and 108. For example, some or all of the
carts in a store may be placed in the recharge stalls 111 of the
cart corral 110 during off-hours or hours when the store is closed
in order for the battery 135 of each cart 10 to be recharged for
the next day or busy period of time.
[0114] In alternative embodiments, the contact plates 105 may be
positioned at other locations on the cart 10 and the charge rail
system 106 may be modified accordingly to provide contact with such
plates as described previously. In an embodiment, contact plates
230, 231 are positioned adjacent to and/or integral with ECM 200 as
shown in FIGS. 6 and 12, which may be advantageous in simplifying
and shortening the flow path between the charge plates and the
battery 135, especially when the battery 135 in integrated in ECM
200. Contact plates 230, 231 would typically be used in lieu of
contact plates 105, as shown in FIG. 12, provided however that dual
sets of contact plates 105 and 230, 231 could be used if desired as
shown in FIG. 6. The location of charge rails 107 and 108 would be
modified, for example raised and/or extended, to engage with
contact plates 230, 231 positioned adjacent to and/or integral with
ECM 200. Likewise, the contact plates 230, 231 could be mounted in
a position extending outward from the ECM 200 as needed to
facilitate engagement with the charge rails 107 and 108. For
example, contact plates 230, 231 may be mounted on protruding or
bulbous ECM 200 side plates 235, as shown in FIG. 12.
[0115] An alternative charge rail configuration is shown in FIGS.
8C-E. The recharge stall embodiment shown in FIGS. 8C-E may
likewise be modular in nature as described herein. FIG. 8C is a
partial front view of cart 10 recharging in a recharge stall 111. A
charging module 190 is mounted to the wheel yoke 191 of rear wheels
138, for example via one or more bolts or other connectors. In an
alternative embodiment, the charging module 190 may be mounted to
the frame 30 or the underside of base tray 50. Preferably, the
charging module 190 is mounted inboard of the rear wheels 38 and
outboard of the front wheels 37, and more preferably on the
interior side of rear wheel yoke 191. A battery charger contact
plate 105 extends downward from the charging module 190. The
battery charger contact plate 105 may be spring loaded to aid in
contacting the contact plate with a charge rail.
[0116] Charge rails 107 and 108 extend upward from the floor
section 113 of recharge stall 111. As shown in FIG. 8C, when a cart
10 is positioned in a recharge stall 111, the charge rails 107, 108
are positioned inboard of the rear wheels 38 and outboard of the
front wheels 37 and serve to guide the cart into the proper
position for recharging. While positioned in recharge stall 111,
the battery charger contact plates 111 enter slots 192 on charge
rails 107, 108 and make contact with rail plate 141 such that
electricity may pass from the recharge stall 111 and charge battery
135. Rail plate 141 may be spring loaded in addition to or in lieu
of spring-loading the battery charger contact plate 105 to aid in
contact there between. The slots 192 in charge rails 107, 108 may
be fully or partially covered by a flexible material such as
plastic or a nylon brush to prevent debris from entering the slots
192. Such flexible material may be pushed aside by the battery
charge plate 105 as it enters the slots 192.
[0117] As shown in FIGS. 8D and 8E, the charging module 190 may
further comprise a contact plate cover 195. As shown in FIG. 8D,
when the cart is not in a charge stall 111, the contact plate cover
195 extends downward to cover and protect the battery charge plate
105. As shown in FIGS. 8D and 8E, the contact plate cover 195 may
comprise a generally U-shaped member having a gap or protective arm
extending there from for receipt of the battery charge plate 105 in
a closed position. The contact plate cover 195 may be biased in a
closed position, for example with a spring. When a cart is
positioned inside a recharge stall 111, the contact plate cover 195
is pushed upward via contact with an upper portion 196 of charge
rails 107, 108, thereby placing the contact plate cover 195 in an
open position as is shown in FIG. 8E.
[0118] In still further embodiments, the charge rail system 106 is
operable to accept a cart 10 in both directions, and fully charge
the cart 10. That is, the charge rail system 106 allows for DC
charging voltages to be accepted in either direction (positive to
ground or ground to positive). A Power Management Unit (referred to
herein as the "PMU") of the charge rail system 106 senses the
presence of a cart 10 on the charge rails 107 and 108. Upon DC
power contact, the PMU determines battery 135 capacity from
previous battery readings prior to charging. The PMU may then
initiate LED status indicators on the charging device (here, a cart
10) to indicate a level of charge and when charging has
commenced.
[0119] In an embodiment, the PMU comprises a PIC processor in the
charging unit and firmware. The PIC processor of the PMU
communicates with the processor in the ECM 220 on the cart 10. The
PMU monitors the communication control between the host cart ECM
200 and the PMU communication interface. If loss of communication
occurs, default protocols may be executed. For example, the charge
rails of the host system (i.e., cart) are shut down and reset or
power to the system (e.g., cart) may be otherwise cycled, thereby
preventing lockup conditions with the host ECM 200 and other
subassemblies.
[0120] The PMU calculates the appropriate charging algorithm to
charge the battery 135. In various embodiments, the calculation of
the appropriate charging algorithm may be based upon voltage and/or
temperature calculations. In various embodiments, the PMU uses
measurement averaging routines to determine the charge routines,
such as trickle charge, full charge, or over/low voltage fault
conditions. Averaging helps to mitigate the effects of contact
chatter when the device being charged (i.e., the cart 10) traverses
the charge rails 107 and 108 (i.e., impedance fluctuations and the
like). In an embodiment, the PMU imposes a delay (e.g., 5 or 10
seconds) from first contact to allow time for the cart to become
fully nested and stop moving prior to commencing charging.
[0121] Additionally, the PMU senses error conditions for voltage
levels or if the PMU loses communication with the host (i.e. the
cart ECM 200), then the PMU initiates a self-reset to recover and
reestablish communication with the cart 10. Error conditions may
include for example too low a voltage, or a very high voltage.
Either case could indicate a bad cell in the battery 135, which
would indicate that the battery 135 should not be charged with full
charge. Error conditions are set in the PMU.
[0122] To prevent deep battery discharge of the cart 10, the PMU in
still further embodiments, senses voltage level of the cart 10 and
calculates remaining charge capacity. If the capacity approaches a
predetermined threshold (such as 20% of remaining capacity, or in
an illustrative system 11 volts), a warning message is issued via
the communications port for system action. If the low voltage
condition persists after a predetermined period of time, the PMU
may automatically shut down the entire system, thereby preserving
the PMU power needed for subsequent operation (i.e. reboot) and
allowing the device (i.e., cart 10) to be charged without replacing
the battery 135.
[0123] In additional power management features, the PMU may be
operable to shut down certain functions of the device to conserve
system power during charging. For example, while the cart 10 is
within the corral 110, the LCD is not needed, the RFID is not
needed, and the like, while the wireless connection is still
needed. By shutting off cart features that consume significant
amounts of power while charging, faster charging is enabled.
[0124] As shown in the Figures, a video display 75 is attached or
mounted (referred to collectively hereinafter as attached) to the
basket 20 of the shopping cart 10. Attachment of the video display
75 to the basket 20 is in contrast to attachment of the video
display 75 to the handle 22. In other words, the video display 75
is not attached or mounted to the handle 22. As shown in FIG. 10,
the video display 75 may comprise a base 76 and a screen 77 having
a viewable area 78. In an embodiment, the video display 75 is
attached to the basket 20 such that the viewable area 78 is above
the interior 54 of the basket as previously defined. Unless
otherwise specified, attaching the video display 75 such that the
viewable area is above the interior 54 of the cart includes, in
various alternative embodiments, having the viewable area 78
entirely above the interior 54; having the viewable area 78
substantially above the interior 54; or having greater than 50, 60,
70, 75, 80, 85, 90, 95, or 99 percent of the viewable area 78 above
the interior 54.
[0125] In another embodiment, the video display 75 is attached to
the basket 20 such that the viewable area 78 is in a field of
vision 84 of a consumer 85 pushing the cart 10 via the handle 22.
Referring to FIG. 9, field of vision 84 refers to the area having a
lower boundary 80 defined by an unobstructed line of sight from the
eyes of consumer 85 to the an upper edge of the basket (e.g., front
edge 29) and an upper boundary 81 defined by a line of sight from
the eyes of the consumer 85 to an upper periphery of the consumer's
vision. Unless otherwise specified, attaching the video display
such that the viewable area is in consumer's field of vision 84
includes, in various alternative embodiments, having the viewable
area 78 entirely in the field of vision 84; having the viewable
area 78 substantially in the field of vision 84; or having greater
than 50, 60, 70, 75, 80, 85, 90, 95, or 99 percent of the viewable
area 78 in the field of vision 84. The field of vision 84 may vary
based upon the height of the consumer 85, and in an embodiment the
shopping cart 10 is configured and the video display 75 is attached
to the basket 20 such that the viewable area 78 is in a field of
vision 84 of a consumer 85 having a height of equal to or greater
than 5 feet and 0 inches. The field of vision 84 may also vary
based upon the position of the child seat 60 or the presence of a
child seated therein, and in an embodiment the shopping cart 10 is
configured and the video display 75 is attached to the basket 20
such that the viewable area 78 is in a field of vision 84 of a
consumer 85 having a height of equal to or greater than 5 feet and
0 inches when the child seat 60 is empty and folded in a closed
position. The field of vision 84 may also vary based upon the
position of products in the basket, and in an embodiment the
shopping cart 10 is configured and the video display 75 is attached
to the basket 20 such that the viewable area 78 is in a field of
vision 84 of a consumer 85 having placed products in the basket,
wherein said products do not extend outside or above the interior
54 of the basket as previously defined.
[0126] In another embodiment, the video display 75 is attached to
an upper edge 26 or 27, or front edge 29 of the basket 20. For
example, the base 76 of the video display 75 may be attached to an
upper edge 26 or 27, or front edge 29 of the basket 20. Various
attachment devices and means for attaching as described herein may
be used with the video display. In an embodiment, the base 76 of
the video display may be attached to an upper edge 26 or 27, or
front edge 29 of the basket 20 such that the viewable area 78 is
above the interior 54 of the basket as discussed previously. In an
embodiment, the base 76 of the video display may be attached to an
upper edge 26 or 27, or front edge 29 of the basket 20 such that
the viewable area 78 is in a field of vision 84 of a consumer 85
pushing the cart 10 via the handle 22 as discussed previously.
[0127] In another embodiment, the base 76 of the video display may
be attached to walls 23 or 24, front side wall 28, and rear side
wall 31 on the interior or the exterior of the basket 20. In an
embodiment, the base 76 of the video display may be attached to a
wall 23 or 24, front side wall 28, and rear side wall 31 on the
interior or the exterior of the basket 20 such that the viewable
area 78 is above the interior 54 of the basket as discussed
previously. In an embodiment, the base 76 of the video display may
be attached to a wall 23 or 24, front side wall 28, and rear side
wall 31 on the interior or the exterior of the basket 20 such that
the viewable area 78 is in a field of vision 84 of a consumer 85
pushing the cart 10 via the handle 22 as discussed previously.
[0128] In another embodiment, the video display 75 is attached to
the nose 45 of the cart 10. The nose of the cart 45 is a well known
area to those skilled in the art. In various embodiments, nose of
the cart 45 refers to the frontward most 1/3 of the basket 20,
alternatively the frontward most 1/4 of the basket, alternatively
the frontward most 1/5 of the basket, alternatively the frontward
most 1/10 of the basket, alternatively the front wall 28,
alternatively front edge 29. In an embodiment, the nose of the cart
is shown in FIG. 10 or FIG. 11. In various embodiments, the video
display may be attached to the nose of the cart via a wall or an
upper edge as described previously and the viewable area 78 may be
above the interior 54 of the basket and/or in a field of vision 84
of a consumer 85 as described previously. In an embodiment, the
base 77 of the video display 75 is shaped to conform to or about
match the contour or shape of the nose 45 of the cart 10, as is
shown in FIGS. 10 and 11.
[0129] The video display 75 may be any suitable electronic display
for receiving and displaying visual images to the consumer 85. The
visual images may be transmitted to the video display 75 by any
suitable means known in the art such as via a wireless
transmission. In an embodiment, the video display 75 is of a type
commonly referred to as a flat screen display, for example an LCD.
The video display 75 may be powered by a rechargeable battery 135
attached to the cart 10 and operatively coupled to the video
display 75.
[0130] In another embodiment, the video display 75 is attached to
the basket 20 and is foldable or retractable for storage. For
example, the video display 75 may fold or retract into the interior
54 of the basket 20 for storage when the cart 10 is not in use. In
an embodiment, the video display 75 is configured to fold or
retract such that a plurality of carts 10 may be nested for storage
as shown in FIG. 12 without damaging the video display 75. For
clarity, the outer cart in FIG. 12 is shown without rear side wall
31, with the understanding that rear side wall 31 would typically
be present in carts used by a consumer 85.
[0131] In an embodiment, the base 76 of video display 75 forms a
housing in which screen 77 may retract. Such housing receives
screen 77 in a retracted position and protects the screen 77 from
damage. The screen 77 may be retracted into such a base housing
(comprising a front base housing 96 and a rear base housing 97) by
known means such as rails, slides, rollers, telescoping members,
and the like, which may be further biased, for example by springs,
as needed. The screen 77 may be retracted to a closed position by
pushing on the top 71 of screen 77 where the screen 77 is biased
up, or by releasing a latch or lock where the screen 77 is biased
in a retracted position. In an embodiment, the screen 77 is folded
down by contact with another cart when nested therewith as shown in
FIG. 12 and is biased up such that the screen flips up upon
unnesting of the carts.
[0132] In another embodiment as shown in FIG. 13, the video display
75 comprises a hinge 79 between the base 76 and the screen 77,
which allows the screen 77 to fold downward toward the interior 54
of the basket 20 into a folded position as shown in FIGS. 10 and
11. In an embodiment, the screen 77 folds at about a 90 degree
angle with respect to the base 76 (or alternatively folds such that
the screen 77 is about within the plane defining the upper edges of
the cart), which clears the nose 45 and exterior of the cart for
nesting with a second cart while also keeping the interior of the
cart 10 clear such that the rear side wall 31 may swing upward into
the interior 54 of the basket 20 to receive the front side wall 28
of a third cart.
[0133] With reference to FIG. 14, the screen 77 of video display 75
may further comprise a shock absorber 94 protecting an electronic
display 95 such as an LCD screen, each of which are disposed
between front and rear screen housings 92, 93. The base 76 of video
display 75 may further comprise a hinge 79 disposed between front
and rear base housings 96, 97. The hinge 79 may further comprise a
gear assembly 91 comprising gears, springs, dampeners, or
combinations thereof for biasing the hinge in a folded or unfolded
position. The gear assembly 91 may be used to control the force
required to fold the screen 77 into a folded position, as shown in
FIGS. 10 and 11, in response to a force applied to a rear screen
housing 93 of the video display 75. Likewise, the gears assembly 91
may be used to control the speed with which the screen 77 unfolds
into an unfolded position such as shown in FIGS. 1-3. In an
embodiment, the screen 77 unfolds in a slow, controlled manner to
avoid damaging the screen 77. In an embodiment, the unfolding of
the screen is dampened via dampeners in the hinge 79 and/or gear
assembly 91.
[0134] In another embodiment, the video display 75 is attached to
the basket 20 and may be swiveled such that the viewable area 78
may be viewed from various locations relative to the cart 10. A
swivel may be positioned between the base 76 and the screen 77 such
that the screen 77 may rotate or swivel about the base. The swivel
may be integrated with the hinge 79, or alternatively may be a
separate component, for example positioned between the hinge 79 and
the screen 77. In embodiments where the video display is mounted on
a side edge 26, 27, the video display 75 may further comprise a
swivel such that the viewable area 78 may rotated to face rearward
toward the consumer 85 while the consumer 85 is pushing the cart
using handle 22. Alternatively, in embodiments where the video
display 75 is mounted on the nose 45 of the cart, the video display
75 may swivel such that the consumer 85 may see the viewable area
78 from locations other than at the rear of the cart. For example,
a consumer 85 may wish to swivel a nose-mounted screen 77 sideways
such that the viewable area 78 is readily viewable while standing
at the side or front of the cart 10. In an embodiment, the video
display 75 may swivel about 180 degrees such that the viewable area
78 faces forward rather than facing rearward toward a consumer 85
pushing the cart 10 via handle 22. From a forward facing position,
the video display 75 may further fold into a folded position such
that the screen 77 is on the exterior of the basket 20 in a folded
position, wherein the viewable area 78 is protected via mating with
the base 76.
[0135] In another embodiment, the video display 75 is attached to
the basket 20 and may be heated such that the screen 77 is readily
operable in cold environments. For example, the video display of
FIG. 9 may further comprise a heating element, which may be
positioned internal or external to the screen housing 92, 93.
Alternatively, the base housing 96 and 97, as described previously,
may be heated such that the screen 77 is kept warm while in a
retracted position. Any suitable heating element that is compatible
with the screen components and operation thereof may be used, for
example a resistive electrical heating element. The heating element
may be powered during storage and/or charging of other components
of the cart 10, for example during charging of the battery 135 for
video display 75.
[0136] Referring to FIG. 15, in an embodiment, the cart 10 further
comprises a read component comprising at least one aisle Radio
Frequency Identification ("RFID") reader 225 with RFID antennas
226, in conjunction with the ECM 200 and software operating
thereon. The read component performs a proximity scan of the cart
10 that reads the area surrounding the cart 10. The number and
position of the antennas 226 may be selected as functionally
needed, as would be apparent to one of skill in the art. The aisle
RFID reader 225 and the antennas 226 may be an integrated component
or may be separate components. In an embodiment, the aisle RFID
reader 225 may be integrated with the ECM 200, for example located
within housing 199. Alternatively, the aisle RFID reader 225 or may
be located at other positions on the cart, for example integrated
into the video display 75 or base/housing 76 or alternatively
located on the underside of the cart 10, secured by means of
attachment to, for example, the bottom 21 of the basket 20, or to
the base tray 50. In an embodiment, the RFID antennas 226 are
located on either side of the housing 199 of the ECM 200.
Alternatively, the RFID antennas 226 may located at other positions
on the cart, for example on side walls 23, 24; on edges 26, 27; on
base side members 32, 33; on the sides of the video display 75; or
any other position suitable for carrying out their intended
function.
[0137] In an embodiment, the aisle RFID reader 225 and/or RFID
antennas 226 may be integrated with the video display, for example
one or both located on the side edges of the video display 75. In
such a placement, the aisle RFID reader 225 and/or RFID antennas
226 are in a location to maximize the effectiveness of the reader
distribution pattern and encompass RFID tags located at various
heights and locations along the shelves, when the video display is
not retracted and the cart 10 is not nested. Placement on the video
display is advantageous as the RFID reader/antenna are positioned
at approximately the middle of the shelf height, thereby allowing
an about equidistant scan pattern above and below the position of
the RFID reader/antenna to cover the complete height of the
shelf.
[0138] In an embodiment, RFID antennas 226 are placed on the side
edges of the video display 75. In some embodiments, patch antennas
may be used for the RFID antennas 226. In alternative embodiments,
the RFID antennas 226 comprise bowtie and/or slot antennas, which
narrow the field of broadcast for the antenna and have a more
focused radiative pattern. As illustrated for a bowtie-shaped
aperture 211 of antenna 212 in FIG. 20A and for a slot-shaped
aperture 213 of antenna 212 in FIG. 20B having an approximate
radiative patterns 207 and 208 of FIGS. 20C and 20D, respectively.
In an embodiment, a bowtie or slot antenna having a beam
approximately eighteen (18) inches wide and approximately six (6)
to eight (8) feet high is used for the RFID antennas 226, and are
placed in vertical alignment parallel with the LCD video display
(and/or at other suitable mounting locations on the cart) such that
the radiative pattern of the antennas provides a narrow slice of
broadcast in the direction perpendicular to each side of the cart
for reading RFID tags located on the shelves or on items on the
shelves on each side of an aisle. In an alternative embodiment, a
bowtie or slot antenna having a radiative pattern of plus/minus 45
degrees (90 degrees total) in a vertical plane covering shelf
height and plus/minus 15 to 22.5 degrees (30 to 45 degrees total)
in a horizontal plane covering shelf width is positioned on each
side of the cart, for example mounted on or integrated with the
video display 75. The use of slot and/or bowtie antennas provides a
more focused field of view for the RFID reader to acquire specific
tags, and thus may assist in eliminating unwanted interference,
echos, reflections, and the like. Thus, the more focused field of
view may also aid in more accurately determining position/location
of the cart, and in particular in combination with other
positioning/locating techniques described herein.
[0139] Various means for attaching and attachment devices may be
used as described herein. In an embodiment, the aisle RFID reader
225 with RFID antennas 226 may comprise a standard or customized
RFID configuration commercially available from for example
ThingMagic, Alien Technology.TM. or an improvement or equivalent
thereof. The aisle RFID reader 225 and RFID antennas function to
read a plurality of active or passive RFID tags positioned
throughout a retail establishment (e.g., along shelves), as will be
discussed in more detail. In an embodiment, the cart 10 is a
plastic cart as described herein which lessens or eliminates
interference associated with the aisle RFID reader 225 and RFID
antennas 226. In an embodiment, the cart 10 is a traditional cart
comprising metal, plastic, or a combination of metal and plastic,
retrofitted with the aisle RFID reader 225 and RFID antennas 226
and other media enhancements.
[0140] In or about a store, a consumer 85 may select a cart 10 from
the cart corral 110 upon entering the store. The motion sensor(s)
36 detect that the cart 10 is moving when the consumer 85 begins to
push the cart 10, and will activate the ECM 200, video display 75,
and the aisle RFID reader 225. As previously noted, various
components of the cart 10 may be hibernated or re-activated based
on motion by the cart to preserve power. In an embodiment, the
video display 75 may initially show the consumer 85 a welcome
display that includes information about the store, explains the
media enhancements to the cart 10, and/or announces in-store
promotions. As shown in FIG. 15, as the consumer 85 pushes the cart
10 through the store, such as between two shelves 301 and 302, a
plurality of RFID tags 303 and 304 (which may be active or passive
RFID tags) located on or near the shelves 301 and 302 respectively,
will communicate with the aisle reader 225 via the antennas
226.
[0141] In an embodiment, the RFID tags 303 and 304 may be
distributed and affixed to objects throughout the store premises.
For example, RFID tags 303 and 304 may be attached (i) at a shelf
or fixture level, which refers to placement of tags at about
regularly spaced intervals along a shelf or other product display
areas such as kiosks, pillars, freezers, refrigeration units,
walls, bins, and counters; (ii) at a SKU level, which refers to
placement and/or incorporation of the tags with or near the
standard SKU label, with a given product typically having one
corresponding SKU tag positioned on the shelf adjacent the product;
(iii) at a product level, which refers to having a tag on each
individual product or package of products, or (iv) combinations
thereof. The aisle reader 225, operably connected to the ECM 200,
will convey a signal comprising informational data to the ECM 200,
causing the video display 75 to present location-based content to
the screen 77. The RFID enablement of the cart permits advertisers
and retail stores to interact with the consumer 85 as she navigates
the store.
[0142] The location-based content is determined as follows. In an
embodiment, the aisle reader 225 with antennas 226 reads any RFID
tag 303 or 304 that comes within a cone-shaped pattern defining an
electromagnetic zone 305 (of the aisle RFID reader 225) on either
side of the cart 10. As noted previously, the shape of the
electromagnetic zone or radiative pattern may be adjusted based
upon the type and positioning of the RFID components on the cart,
for example use of bowtie and/or slot antennas. The shape of the
electromagnetic zone 305 read by the aisle RFID reader 225 may be
another shape, other than a cone, according to the particular aisle
RFID reader 225 employed, and the range (i.e. proximity within
which tags may be read by the reader) is likewise determined by the
particular aisle RFID reader 225 and antenna 226 array
employed.
[0143] When an RFID tag 303 or 304 passes through the
electromagnetic zone 305, the tag is activated and communicates
with the aisle RFID reader 225 according to known RFID techniques.
A locationing component (which in an embodiment comprises the aisle
RFID reader 225, in conjunction with the ECM 200 and software
operating thereon) determines the location of the cart 10 in the
store by processing signals from any number of RFID tags 303 or 304
that are within range of the aisle RFID reader 225. The location of
the cart 10 relative to specific RFID tags 303 or 304 is determined
according to well known RFID positioning techniques. In an
embodiment, location may be determined based on the strength of the
signals coming from the RFID tags 303 and 304 (i.e. highest number
of scans read by the aisle RFID reader 225 indicates which tag or
tags 303 and 304 are closest).
[0144] In an embodiment, the process of locating the cart 10 begins
by creating an electronic representation of the store configuration
including fixtures, aisles, and other relevant data using the
location of a number of reference or anchor RFID tags (e.g., shelf
or fixture level tags) placed around the store in known locations.
This electronic representation provides a base map of the store.
The base store map may be built using the cart 10 by placing the
anchor RFID tags in the known locations around the store, taking
the cart 10 through various routes throughout the store to read
each of the anchor RFID tags, and correlating the read data with
the known data. The base store map is materialized as either
database entries or an xml document generated from the correlated
data. The base store map provides reference data for determining
the location of other goods or items in the store. As fixtures,
items, and/or anchor tags are moved within the store, the base
store map may be updated by taking the cart 10 through the store
again to obtain fresh data and correlate it with the updated known
anchor RFID locations.
[0145] Against the backdrop of the anchor RFID tags, a series of
virtual locations are created and positioned within the defined
framework of the store, i.e., the base store map. Each location,
such as for example a shelf, freezer fixture, aisle, or produce
bin, can then be defined as associated with one or more anchor RFID
tags, which may be active or passive tags, as previously noted.
Such known locations may be used to determine the location of the
cart, for example using the RFID locator service software routine
described below. Furthermore, the known locations may be correlated
to specific products, for example via use of additional SKU level
and/or product level RFID tags. For example, a given product such
milk may be correlated to a specific refrigerator having a known
location within the base store map. Via such correlation, the
location of specific products can be provided relative to the known
location of the cart within the store, and the consumer may be
provided directions to such products.
[0146] In various embodiments, subcategories may be used for
product positioning instead of positioning every single product
with a location in the store. Using subcategories simplifies store
deployment. Each product is tied to a subcategory, and each
subcategory is in turn associated with a location in the store.
Thus, milk may be assigned to dairy or milk may be a subcategory
including all brands and varieties of milk (e.g., whole, skim,
etc.).
[0147] As discussed herein, the aisle RFID reader 225 is located
upon the cart with the RFID antennae 226 oriented facing outward
from the cart. Given that the cart and associated RFID reader is
mobile within the store whereas the RFID tags are typically
stationary within the store, various RFID data along with other
positioning information (for example, motion sensor data) may be
gathered and analyzed using software algorithms, for example
operating on ECM 200 or a remote location such as a store server
and provided to the cart. The antennae configuration (position,
orientation, type) is made known in inputs to the software
processes involved in locating the cart in the store, as well as
performing useful tasks such as shelf management for tasks
including inventory, price changes, and the like. The RFID are
evaluated using the known antenna orientation and configuration in
order to determine cart orientation.
[0148] For instance, at a recurring interval, the aisle RFID reader
225 may perform an inventory by recording RFID information for
products located on the shelves and correlating the recorded
information with the store's system. The results of the inventory
may then be analyzed and used in decisions regarding orders for
additional products and product placement in the store.
[0149] In locating the cart (which may then be used for determining
the placement of advertisements in the video display 75, store
purposes, or data mining for external or internal uses), for each
antenna, the RFID tags "in view," or located within the radiative
pattern of the antenna 226, are evaluated. The evaluation process
uses several pieces of information to determine the location of the
cart within the store, and specifically within the electronic base
store map defined above.
[0150] The RFID locater service software routine that encompasses
these functions performs location inventory and store mapping that
is used to determine what any given cart is doing within the store,
and provides an added level of accuracy in addition to the RFID
location determination. The intelligence involved in the RFID
locater service intelligently links what is read by the aisle RFID
reader 225 with information known about the store based on the base
store map and the known locations of anchor RFID tags. In an
embodiment, the anchor RFID tags may be located at regular
intervals, such as every 2 feet along the shelves, or on each side
of fixtures such as produce bins, and the like. The RFID locater
service additionally incorporates knowledge about RFID dead zones,
such as foyers or the locations surrounding large metal fixtures
that may interfere with RFID signals, so that locating the cart 10
is smooth and continuous regardless of where the cart is located in
the store. For example, metal refrigerators tend to generate a lot
of reflections such that RFID readings in the vicinity of a
refrigerator are full of noise. The RFID locater service can
account for known reflections in such an area, and adjust what the
RFID reader 225 reads in such an area.
[0151] In an embodiment, location is determined via a scan to
determine what products and items are in proximity to the cart
(i.e., an inventory of tags read by the scanner) and correlating
same to the cart's determined position to check the accuracy of the
determined position and correct same as needed. The ECM 200 issues
a read command to the aisle RFID reader 225. The locator software
process then evaluates the read RFID tags (e.g., SKU and/or product
level tags) to eliminate tags generating spurious reads, i.e.,
those included in the read that are not RFID tags associated with a
location as established via the anchor RFID tags (e.g., shelf level
tags). The remaining tags are then converted to locations indicated
in the map. All of the locations (e.g., all RFID tag data) may then
be evaluated to determine the cart location and orientation
relative to the locations defined in the base store map. Such RFID
data may be further correlated with other locationing means and
data such as motion sensors such as the reed switch described
herein. In this process, the software assumes and takes into
account the anticipated read zone of the two antennae. If evaluated
individually, each tag indicates the orientation of the cart. The
overall orientation is determined by evaluating the orientation
differential of each tag location from the orientation indicated by
the complete location inventory. The "outlying" locations providing
an orientation that is substantially out of correlation in
comparison with the others within the inventory are removed, given
that they represent spurious locations derived from spurious tag
reads.
[0152] In some cases, RFID reads during inventory will be
non-deterministic. Inconsistencies in the RF environmental (e.g.,
reflections, nulls, false reads, signal collisions, etc.), physical
obstructions, technology failure and other factors may cause
unpredictable inventory responses. Spurious reads are defined as
those that are inconsistent with the results expected for the cart
in a given position and orientation. For example, one spurious read
would occur for a tag that shows up in the inventory that is
outside the maximum expected read range of the aisle RFID reader
225. Furthermore, transient reads are defined as those that are
consistent with the expected results for a given cart position and
orientation, but that do not consistently appear in a set of
inventory reports collected over an arbitrary period of time.
[0153] With the inventory of locations in the system, locations may
then be evaluated to determine cart position as a relative x,y
coordinate within store map. The system employs a location buffer
to smooth out errors introduced by transient tag reads. The
remaining locations are evaluated, and an average x,y position is
calculated. The nearest location (among the inventory locations) to
the calculated location is determined and the cart position is
adjusted according to which location is nearest. This adjusted
position is then compared to the map and further adjusted as
necessary to position the cart accurately within the map. Such
positions and data may be further compared to known/mapped routes
or paths within the store to further assist in determining the
location of the cart. For example, if may be know that a consumer
will likely travel a certain path based upon the position within
the store and same may be used to help track and position the cart
as it traverses the anticipated path.
[0154] A number of rules may be applied in the evaluation of the
inventory location to improve the accuracy of locating the cart,
and therefore also the efficacy of the cart 10 as a shelf
management tool. For example, a temporal rule may be applied such
that recent tags reads are prioritized above older reads into
determining cart position. Additionally, recent location reports
may be used in determining if a particular tag represents a
spurious read.
[0155] Similarly, a volume rule may be applied, such that a large
volume of tag reads occurring during a given time frame are
prioritized above smaller volumes of tag reads for determining cart
position. For example, a RFID tag "seen" by the aisle RFID reader
225 twenty times during the last second is prioritized above a RFID
tag "seen" only one time during the last second. Likewise, a
proximity rule may be applied, wherein RFID tags in the inventory
that are proximate to one another are prioritized above RFID tags
in the inventory that are not proximate. In such a case, proximity
is based upon the base store map and business rules.
[0156] In various embodiments, the accuracy of the determination of
cart location is improved by the addition of the magnetic reed
switch, discussed previously as an embodiment for the motion
sensor(s) 36. The rotational speed of each wheel may be determined
based on the "heartbeat" signal generated each time the magnet
opens or closes the magnetic reed switch, preferably without
physical contact thereof, when the wheel turns. By placing a magnet
and reed switch assembly on two wheels, such as, for example, on
both back wheels, the ECM 200 may determine when the cart 10 is
turning as an added factor in accurately determining the location
and orientation of the cart 10. Specifically, when the cart 10 is
turning, such as around a corner or to enter a next aisle in the
store, the wheel to the inside of the turn will not rotate as much
as the wheel to the outside of the turn, and by comparing the
difference in rotational speed of each wheel, the ECM 200
locationing component may incorporate the knowledge that the cart
10 is turning a corner or turning around to supplement the
locationing performed by the aisle RFID reader 225 and antenna
226.
[0157] In various embodiments, the locationing component further
includes an integrated compass for additional optimization of
locationing for the cart. In some embodiments, the integrated
compass is a digital compass. The compass provides various
functions, including enabling the provision of an enhanced path
layout for precise data reporting of shopping events. Another
function of the compass is to provide directionality or a heading
for the cart 10 in a store map. For example, the directionality
provided by the compass enables display of a direction icon in a
store map to identifiable areas of the store. For example, the
point of sale (i.e., check out) area of the store, restrooms, store
exits, and store departments. Such directionality is relative to
the present location of the cart based on the proximity scan as
described herein.
[0158] In various embodiments, the accuracy of the determination of
cart location is improved by the addition of an Automatic Gain
Control ("AGC") module. The use of an AGC module to control the
transmit power and/or antenna attenuation of the aisle RFID reader
225 provides still another means of improving the accurate
determine of cart location and, therefore, product awareness. In
operation, the AGC module, which may be implemented in a software
routine and executed from the ECM 200, automatically controls each
antenna 226. Specifically, the AGC may be used, as understood by
one of ordinary skill in the art, to either increase the transmit
power or adjust attenuation. By doing so, sensitivity to tags may
be controlled so that tags that are "unexpectedly" read, in that
they are not located within the expected radiation pattern of the
antenna 226 and aisle RFID reader 225 yet still are read, may be
avoided. For example, the cart 10 may be located on aisle 4, but
unexpectedly is reading tags from adjacent aisles 3 and 5. Tags
from the adjacent aisle are "unexpected" based on the presently
determined cart location. To correct for the unexpected tags, the
AGC adjusts the attenuation or power of the read signal, such that
the tags from the adjacent aisles are no longer read. In another
example, the cart 10 may be located on aisle 4, but is not reading
all of the "expected" tags for aisle 4. In order to correct for the
missing, but expected tags, the AGC adjusts the transmitted power
until the expected tags, based on the cart's presently determined
location, are read by the aisle RFID reader 225. The AGC module may
particularly be useful for improving accuracy of cart location in
areas with higher interference or when many carts are in close
proximity. By adjusting transmit power and/or attenuation (i.e.,
providing automated, real-time, dynamic power control from the RFID
reader/antennae), the AGC module provides the additional advantage
of conserving power by adjusting the power such that an appropriate
and efficient amount of power is used in reading the RFID tags.
[0159] In testing, it has become clear that as there are more RFID
tags broadcasting, it becomes more and more complex to discern
whether there is a good transmit and receive from a particular RFID
tag among the group. The present system presents a special
challenge in that other applications do not use as many readers as
close together. The present system has a uniquely high number of
RFID readers in close proximity to one another, and the number of
readers in close proximity to one another is constantly changing as
carts move around.
[0160] Two things happen when the number of RFID readers in close
proximity to another is a large number and constantly changing.
First, passive RFID tags become saturated by all the RF energy.
Second, each reader becomes saturated by too much interference,
resulting in a phenomenon referred to as dense reader mode. Dense
reader mode is when multiple RFID readers are broadcasting and
receiving RFID information and the resulting RFID read performance
is fluctuating and/or decreasing from the available number of RFID
tag reads within the useable read range of the RFID tags.
Specifically, dense reader mode is a mode of operation that
prevents readers from interfering with one another when many are
used in close proximity to one another.
[0161] As discussed previously, it is possible to partially
optimize RFID reader performance by increasing or decreasing the
gain until an optimal number of tags are detected. However, upon
further testing, it has become apparent that additional
optimization may be achieved by increasing or decreasing other
characteristics in addition to power. For example, in addition to
adjusting power up or down, RFID reader performance is optimized by
increasing or decreasing the duty cycle (i.e. the transmit on and
off time such as broadcast on for 2 seconds, and off for 8 seconds
for a 20% duty cycle). Additionally, RFID reader performance may be
further optimized by adjusting the antennas themselves. As there is
an antenna directed to both sides of the cart (or alternatively, a
single bidirectional antenna), each can be adjusted individually
such that the antennas (or directions for a single antenna) are not
matched, until an optimal number of tags are detected. For example,
it is possible to alter the sleep time (i.e., the duty cycle for
one antenna or antenna direction as relative to other antenna or
antenna direction respectively).
[0162] Such optimization allows a greater number of readers to
function with a limited RF domain. Such optimization also allows a
large number of readers to co-exist within a small fixed area, such
as in the Point of Sale (i.e. check out) area of a store.
[0163] In an embodiment, the locationing component is similarly
operable to determine the location of a given product relative to
the shopping cart 10 based on signals from the read component. The
locationing component then displays on the video display 75 the
location of the given product in relation to the cart 10. In an
embodiment, the locationing component may comprise software,
hardware or a combination of hardware and software operable to
determine the location of the shopping cart or a product in the
store. The locationing component may, in an embodiment comprise
hardware affixed to the cart with software incorporated therein, or
may, in an embodiment, comprise hardware affixed to the cart
operably coupled with software stored in and/or executed from the
ECM 200 or another networked component. In an embodiment, the
locationing component may be integrated within the ECM 200.
[0164] In an embodiment, the location of the given product in
relation to the location of the cart 10 may be graphically
displayed on the video display 75 on a floor plan of the store,
using an indicator to show the location of the cart 10 on the floor
plan of the store and another indicator to show the location of the
given product on the floor plan of the store. In an embodiment, the
indicators may comprise directional arrows 309, as will be
discussed further below. In an embodiment, the location of the
given product in relation to the location of the cart 10 may be
described using words relative to a floor plan of the store. For
example, such a written direction may be provided in the video
display 75 by indicating "You are on Aisle 2, the Product you are
looking for is on Aisle 9 to your left."
[0165] In an embodiment, the locationing component is operable so
as to locate a given product being displayed in an advertisement on
the video display 75 relative to the shopping cart 10. In an
embodiment, the locationing component then displays on the video
display 75 the location of the product being advertised in relation
to the cart 10. In an embodiment, the location of the product being
advertised in relation to the location of the cart 10 may be
graphically displayed on the video display, using an indicator,
such as an arrow, displayed adjacent to or as part of the
advertisement to point towards the location of the product being
advertised. In an embodiment, the location of the product being
advertised in relation to the location of the cart 10 may be
described using words to indicate to the consumer where she may
find the product being advertised. For example, in or adjacent to
an advertisement for laundry detergent, an indicator reading
"Laundry Detergent ahead on the right" may be displayed based on
the location of the cart.
[0166] Referring now to FIGS. 16, 17 and 18, upon determining the
proximity of the cart 10 to any particular tag or tags 303 or 304,
the ECM 200 causes at least one advertisement 306 to be displayed
to the consumer 85 on the video display 75. The advertisement 306
displayed may be selected from a plurality of stored advertisements
307, and the advertisement 306 may be selected based on the
proximity of the cart 10 to a particular tag or tags 303 or 304. In
an embodiment, the plurality of stored advertisements 307 may be
stored in the ISS 330, streamed to the ECM 200 via a wireless LAN
(e.g., transceivers 205 mounted in the store communicating with the
network transceiver 204 in ECM 200), and displayed on the video
display 75 according to the location of the cart 10. In an
embodiment, the plurality of stored advertisements 307 may be
stored in local memory 202 in the MOD, accessed, and displayed on
the video display 75. When the cart 10 enters a different area of
the store and the aisle RFID reader 225 detects different RFID tags
303 or 304, the location of the cart 10 is updated, and the
advertisement 306 is changed to reflect a different one of the
plurality of the stored advertisements 307 based on the updated
location of the cart 10.
[0167] As shown in FIG. 16, in an embodiment, the screen 77 of the
video display 75 may be divided into a plurality of screen segments
308, such that one of the plurality of stored advertisements 307
may be displayed in each screen segment 308. In an embodiment, one
of the plurality of screen segments 308 may be designated for
display of consumer specific information, such as the running total
of the products in the cart 10, loyalty card or other consumer
identifying information, product information pertaining to a
specific product recently placed in the cart 10, and the like.
[0168] Referring again to FIG. 16, an exemplary display of
advertising is shown. In an embodiment, a selected number of the
plurality of stored advertisements 307 (equal to the number of
screen segments 308) are displayed in the screen segments 308.
Directional arrows 309 may be provided as an indication to point in
the general direction of the advertised product on adjacent
shelves. In an embodiment, one screen segment 308a may be more
prominently sized than the other screen segments 308b, such that
one of the plurality of stored advertisement 307 is displayed in
the more prominently sized screen segment 308a, while others of the
plurality of stored advertisements 307 are displayed in the less
prominently sized screen segments 308b. This division of the screen
77 into screen segments 308 may be analogized to advertisements in
a newspaper, wherein various of the advertisements may use one
half, one quarter, one third of a page, etc. to fill a page with
advertisements, and the cost of running an advertisement in each
portion of a page may relate to the size of the advertisement
relative to the rest of the page, the prominence of the
advertisement on the page, the duration of time the advertisement
is on the page, or combinations thereof. In an embodiment, the
selected plurality of stored advertisements 307 may rotate being
displayed on each screen segment 308, such that the most prominent
screen segment 308 displays each of the selected ones of the
plurality of stored advertisements 307, one after another, based on
the time each one of the plurality of stored advertisements 307 has
been displayed, or based on the location of the cart 10 between the
shelves 301 and 302 in proximity to tags 303 and 304, which may be
further correlated to the proximity of the cart to the advertised
product on the shelf.
[0169] Rather than showing multiple advertisements in various
screen segments, a single advertisement at a time may be displayed
in a screen segment generally reserved for advertising. A
multi-tier approach may be used to determine pricing of
advertisements when a single screen segment is devoted to
advertising, given that the newspaper analogy may not apply. For
example, advertising may instead be sold for zones of the store,
whether based on what types of products will be shelved there, or
based on consumer traffic patterns in the store. For example,
pricing may be different and the types of advertisements that will
be effective will vary based on whether the advertisement segment
is purchased for advertisements to be displayed along high traffic
routes such as the front aisle of the store, or the lower traffic
areas, such as the pharmacy or deli. Selling advertising based on
when and where it will be displayed may permit advertising
companies to make decisions to effectively market products even
while only one advertisement is displayed at a time in the video
display 75.
[0170] In an alternative embodiment, no one screen segment is sized
more prominently than the other, but rather, a simplified, unique
split screen Graphical User Interface ("GUI") is shown, as is
illustrated in FIG. 21A. The unique attributes of the GUI are
associated with cart operation and LCD display position. The GUI
provides the consumer with user-friendly easy access to cart
functionality while maintaining readability and utility as viewed
from the nose-mounted position at the opposite end of the cart from
the consumer.
[0171] The GUI may be adjusting to one of a plurality of user
levels, providing basic, intermediate, or advanced functionalities
of the enhanced cart 10 based on how the consumer prefers to use
the cart 10. The GUI shown in FIG. 21A enables the consumer to
access the basic level of functionality, and does not require the
use of any identifying information associated with the consumer to
carry out the functions. In an embodiment, the video display
defaults to the basic level of functionality when the cart 10 is
powered on. The basic level of functionality displayed in the menu
includes "Find Item," "Store Specials," and "View Help," each of
which may be displayed in the form of a button, textual link or the
like for selection by the consumer. In the segment below the menu,
space is reserved for display of an advertisement that is placed
there when so indicated by the ECM 200, as discussed herein. Upon
selection of a menu item, the GUI changes for each functional menu
item.
[0172] Upon selecting "Store Specials," the GUI reflects the view
of FIG. 21B. In FIG. 21B, the Store Specials are shown, along with
a button or link to show a full screen view of the store specials
(which eliminates the space below reserved for display of
advertisements), or return to the main menu. If the "Full Screen"
is not selected, the space for display of advertisements remains
displayed.
[0173] Upon selecting "View Help," the GUI reflects the view of
FIG. 21C. In FIG. 21C, a menu appears that presents to the consumer
the choices of "find item," "store specials," "price check," and
more, according to the desires of the store for which the cart is
configured. A link for a tutorial on the use of the cart 10 may be
provided, along with a button or link to return to the main
menu.
[0174] From the "View Help" view of the GUI, when "Find Item" is
selected, the GUI provides the view of FIG. 21D, wherein the user
may scroll and select letter or number characters using the
five-way navigation device 123. Additional links for returning to
the main menu or viewing a store map may also be provided. The
store map provided by the link, as shown in FIG. 21E, may
graphically indicate where in the store the cart is located as well
as the location of an item for which the consumer is searching
using the "Find Item" feature.
[0175] From the "View Help" view of the GUI, when "Price Check" is
selected, the GUI provides the view of FIG. 21F, which displays a
price (or prices, if a sale price is additionally available, or if
a discount price is available for loyalty consumer 85s). In the
price check view, the consumer may scan a product using the scanner
215, and the price is displayed. Also, as seen in FIG. 21F, an
advertisement may be displayed in the space reserved for
advertisements. The price check feature may be activated via a
price check button as described herein.
[0176] Referring now to FIG. 23, an exemplary scrolling menu for a
user interface is shown in accordance with embodiments of the
present disclosure. In an embodiment, content displayed on the
video display 75 is navigated and controlled by way of a scrolling
menu 1100. The scrolling menu 1100 includes a plurality of
functions that may be selected, each function represented by a
graphical icon 1102a-d. The scrolling menu 1100 rotates the
functions, represented by icons 1102a-d, as directed by a user, for
example when the user indicates an upward scrolling motion, a
downward scrolling motion, or sideways scrolling motion with the
five-way navigation device 123. The scrolling menu 1100 may present
the functions in a horizontal or a vertical presentation (as shown
in FIG. 23), which may be navigated using the relevant directional
controls of the five-way navigation device 123. The scrolling menu
1100 may additionally include indicators of direction 1104 in order
to help users determine how to use the directional control to
scroll through the scrolling menu functions. In various
embodiments, each function may alternatively or additionally be
represented by text that easily identifies the function to a user.
The text indicating a function may likewise be scrolled around
within the scrolling menu.
[0177] The scrolling menu includes a selection position 1106, such
that when a particular function icon (1102b as shown) is scrolled
into the selection position 1106, content associated with the
function icon is displayed in some or all of the remaining space
visible in the video display 75. The video display 75 dynamically
magnifies the content associated with whatever function icon is
presently in the selection position 1106, in order for the user to
see and use the associated content to achieve an objective that the
function offers.
[0178] In various embodiments, the selection position 1106 is
indicated by an icon 1108 that differentiates the selection
position 1106 from the other positions in the scrolling menu 1100.
As shown in FIG. 23, the selection position 1106 is indicated by a
right-facing arrow (i.e., the icon 1108), indicating that the
associated content for the function in the selection position 1106
is magnified in the area of the video display 75 to the right of
the selection position 1106. In alternative embodiments, any icon
may be used to indicate the selection position 1106, such as a
magnifying glass or other attention-getting graphical icons or text
such as the box 1106 shown in FIG. 23.
[0179] In the video display 75, the available display space may be
apportioned into at least two areas, though in various embodiments,
the available display space may be apportioned into more than two
areas. As shown in FIG. 24, in a first area 1200 of the available
display space, the scrolling menu 1100 may be presented, while in a
second area 1201 of the available display space, content 1110 is
displayed, wherein the content 1110 is associated with the
particular function presently displayed in the selection position
1106 of the scrolling menu 1100. As the scrolling menu 1100
scrolls, the content 1110 displayed in the second area 1201 of the
display space dynamically changes, preferably as rapidly as the
user is scrolling the scrolling menu. As such, when each function
icon is within the selection position 1106, the content 1110
associated with that function is displayed, and the instant that
the function within the selection position 1106 changes, so does
the content 1110 displayed in the second area 1201.
[0180] Thereby, the user is presented with a real-time graphical
display that changes according to her wishes and comfort level with
using the user interface. For example, an elderly consumer who is
not accustomed to using a computer or a first time user of the
media enabled shopper cart may scroll the scrolling menu slowly,
and the associated content is displayed at the same rate, as she
scrolls the menu, affording her as much time as she needs to look
at and become familiar with the content. By comparison, a shopper
who is more familiar with using the media enabled shopping cart may
scroll the menu quickly to use functions that she is already
familiar with, and will be displayed the selected feature
dynamically, in real time.
[0181] In embodiments having the available display space
apportioned into more than two areas, additional space may be used
to display, for example, advertisements, a help function in
addition to the function in the selection position, a store map,
instructional photographs (for example, a photograph showing the
user how to scan a product for a price check), and retailer sales,
promotions, or logos. As may be seen in FIG. 25, the first area
1200 is used to display the scrolling menu 1100, the second area
1201 is used to display the content 1110 associated with the
function in the selection position 1106, and a third area 1202 of
the available display space is used to display an advertisement,
which may be selected based on the location of the cart within the
store, or based on historical information known about the
consumer's purchasing habits.
[0182] The scrolling menu 1100 may include any number of different
functions, including, for example, a "Price Check" function,
enabling the consumer 85 to scan an item to see the item's price, a
"Store Special" function, enabling the consumer 85 to review (and
optionally find on a store map) reduced or special price items, an
"Item Finder" function, enabling the consumer 85 to request the
location of a particular product, and a "Help" option, enabling the
consumer 85 to receive helpful tips for use of the media enabled
shopping cart. Additional optional functions may include various
service functions, such as an interface with an in-store pharmacy
for the consumer 85 to request the status of their prescription or
receive notification of prescription availability, an interface
with an in-store deli for the consumer 85 to make a deli order or
receive notification of order availability, an interface for
notification to the consumer 85 of completion of in-store auto
servicing, an interface for interaction between the consumer 85 and
customer service personnel for services such as rain checks, and
other functions for in-store services.
[0183] Some or all of these functions may be included in the basic
level of functionality. In addition to these functions, additional
functionality of the cart 10 is available to users who desire to
additionally enhance their shopping experience at an intermediate
level of functionality and at an advanced level of functionality.
At the intermediate level of functionality, the consumer may scan
products at the cart 10 using the scanner 215, view the scanned
cart contents and a running total, and remove an item from the cart
by scanning an item that has already been placed in the cart 10.
The intermediate level of functionality may be accessed by a
consumer by simply starting to use the scanner 215. To use the
intermediate level of functionality, the consumer is not required
to identify himself or herself, but may do so using a loyalty card
associated with his or her identity, or by simply using a PIN. The
consumer has the option to use a consumer created Personal
Identification Number (PIN) which is unique to the consumer, but
may or may not be associated with any consumer information such as
name, address, and the like, in the same manner as a loyalty card
identifier. Using a PIN, the consumer may retrieve saved electronic
shopping lists, favorite recipes, and nutritional information in
some advanced features, but does not have to identify him or
herself with a name and address. In an embodiment, the PIN
comprises a phone number, optionally with a security code.
[0184] In an embodiment, the level of functionality selected and
the resultant display screens and features made available to a
consumer 85 is based upon existing data entered by the user or
gathered from previous use of the cart 10 by the consumer 85. For
example, upon scanning of a loyalty card or entry of a PIN, a
database may be consulted to determine what level of functionality
the consumer 85 has selected or previously used, and then the
appropriate functionality and display screens are presented to the
user. Such data can be tracked over time and functionality adjusted
to correspond to preferences and usage by the consumer 85. For
example, as the consumer 85 becomes experienced in using the
system, more detailed information and functionality may be provided
to the consumer 85. Alternatively, tutorials or other help
functions may be provided for inexperienced users.
[0185] At the advanced level of functionality, the consumer may
additionally perform a cart level express check out, when products
for purchase have already been scanned, view nutritional
information and recipes, and view lists according to store
departments. The consumer may also create, save, and retrieve
electronic shopping lists, and obtain loyalty card prices and
promotions.
[0186] In various embodiments, when the consumer identifies himself
or herself to the cart 10 by way of a loyalty card, a consumer
privacy notice may be displayed. The privacy notice may be
displayed upon the first use of the cart 10 by a particular user
who has identified himself or herself by way of a loyalty card, and
thereafter, when the consumer identifies himself or herself via a
loyalty card, the privacy notice will not be displayed since it has
been displayed and accepted by the consumer before.
[0187] The unique attributes of the GUI are associated with cart
operation and LCD display position. The GUI provides the consumer
with user-friendly easy access to cart functionality while
maintaining readability and utility as viewed from the nose-mounted
position at the opposite end of the cart from the consumer.
[0188] Referring now to FIG. 24, when the function icon for "Price
Check" is scrolled in the scrolling menu 1100 to the selection
position 1106, content 1110 associated with the price check
function is displayed in the second area 1201. Specifically, the
content 1110 may include instructions to a user, either textually
or graphically, for how to carry out a price check. In various
embodiments, the instructions indicate that to check a price of an
item, the consumer 85 presses a particular one of the buttons of
the five way navigation device 123, and scans the item's UPC code
using the scanner 215.
[0189] The content 1110 associated with the price check function
may additionally include, as shown in FIG. 24, a helper icon 1205
to offer the consumer 85 an additional way to seek information, or
a tutorial, on the use of the price check function. Although not
shown in FIG. 24, but discussed above, an advertisement, such as an
advertisement for the item for which the price is being checked,
another product made by the same company, or a competing product,
may be displayed in a third area reserved for advertisements
1202.
[0190] Upon a scan of an item by the consumer 85 while the content
associated with the price check function is being displayed, the
user interface dynamically changes to display the results of the
price check, i.e., a price (or prices, if a sale price is
additionally available, a discount price if available for loyalty
consumer 85s, or a per unit price) as shown in FIG. 25. The results
of the price check may be displayed in a full screen, consuming all
available display space not used for displaying the scrolling menu,
or may be displayed in one area, such as a second area 1201, while
a third area 1202 is used for displaying other content, such as an
advertisement for the item for which the price is being checked,
another product made by the same company, or a competing
product.
[0191] Additionally, as shown in FIG. 25, a Price Check History may
be displayed including each item for which the consumer 85 has
performed a price check during the particular shopping trip. The
Price Check History may be used by the consumer 85 to perform
comparison shopping, or to decide which items to keep for purchase,
and which items to return to a store shelf. An icon may be provided
for clearing the Price Check History.
[0192] Referring now to FIG. 26, when the function icon for "Store
Specials" is scrolled in the scrolling menu 1100 to the selection
position 1106, content 1110 associated with the store specials
function is displayed in the second area 1201. Specifically, the
content 1110 may include an item description 1401 and a feature
price 1402 for each item priced for Store Specials (such as weekly
specials). The item description 1401 may include a product name
brand (e.g., Pringles.TM.) and type (e.g., Original), as well as a
size (e.g., 6 ounces) purchased for the feature price 1402. In
various embodiments, the content 1110 associated with the store
specials function may include instructions to indicate that to view
a location for a particular item from the list displayed for store
specials, the consumer 85 may press a particular one of the buttons
of the five way navigation device 123 while highlighted the
particular item in which she is interested, and a location of the
product relative to the present location of the cart may be
displayed in a store map.
[0193] The list of store specials items may be displayed in a full
screen, consuming all available display space not used for
displaying the scrolling menu 1100, or may be displayed in one
area, such as a second area 1201, while a third area 1202 is used
for displaying other content, such as an advertisement, which may
be selected based on the location of the cart within the store, or
based on historical information known about the consumer's 85
purchasing habits.
[0194] The content 1110 associated with the store specials function
may additionally include, as shown in FIG. 26, a helper icon 1205
to offer the consumer 85 an additional way to seek information, or
a tutorial, on the use of the store specials function.
[0195] Referring now to FIG. 27, when the function icon for "Find
Item" is scrolled in the scrolling menu 1100 to the selection
position 1106, content 1110 associated with the item finder
function is displayed in the second area 1201. Specifically, the
content 1110 may include a keyboard 1500 in the second area 1201
and a list of items in store inventory 1502 pertaining to the
search may be displayed in a third area 1202. The graphical
keyboard 1500 displayed in the second area 1201 may be navigated by
the consumer 85 using the five way navigation device 123.
Specifically, the consumer 85 may use arrow buttons of the five way
navigation device 123 to scroll through the letters in the keyboard
1500, and press the center button or "*" button in order to select
a character. Using the keyboard, the consumer 85 may spell out the
brand name or the item name for a product.
[0196] Upon the consumer 85 typing a first letter of the brand name
or item name of a sought after product 1508, the list of items in
store inventory 1502 pertaining to the search may be narrowed to
items in the store inventory that start with the letter that was
typed. For example, as shown in FIG. 27A, when the letter "T" is
entered in the keyboard 1500, the list of items in store inventory
1502 is narrowed to only items with a brand name or item name in
store inventory that start with the letter "T." Upon the consumer
85 typing a second letter of the brand name or item name of the
sought after product 1508, a narrowed list 1504 of the items in
store inventory pertaining to the search may be displayed. For
example, as shown in FIG. 27B, when the letter "A" is entered in
the keyboard 1500, the list of items in store inventory 1502 is
narrowed to the narrowed list 1504 to include and display only
items with a brand name or item name in store inventory that start
with the letter "T" and the next letter is the letter "A."
[0197] Likewise, upon the consumer 85 typing a third letter of the
brand name or item name of the sought after product 1508, a further
narrowed list 1506 of the items in store inventory pertaining to
the search may be displayed. For example, as shown in FIG. 27C,
when the letter "C" is entered in the keyboard 1500, the list of
items in store inventory 1502 is narrowed again to the further
narrowed list 1506 to include and display only items with a brand
name or item name in store inventory that start with the letter
"T," having the second letter as the letter "A," and having the
third letter as the letter "C," and so on. The consumer 85 may
enter as few or as many letters of the brand name or item name of
the product he or she seeks to find, such that if all letters of
the name are entered, the list 1502 is narrowed to only the item he
or she seeks to find. The consumer 85 may enter fewer than all of
the letters of the name, and once the list is narrowed sufficiently
to display in the list the sought after item, the consumer 85 may
select the item from the list 1502, 1504, 1506, or so on.
[0198] Upon selection of the item from the list 1502, 1504, 1506,
or so on, the result of the "find item" is displayed, identifying
the sought after product 1508. Specifically, the location of the
sought after item 1508 is displayed on a store map 1600 relative to
the present location of the cart as shown in FIG. 28. The present
location of the cart may be indicated with an icon representing the
cart 1602, and the location of the sought after item 1508 may be
indicated with an icon representing the item 1604. In various
embodiments, an icon representing "zoom" 1608 may enable the
consumer 85 to zoom in on the map for an additional level of detail
to find the sought after item 1508.
[0199] The content 1110 associated with the item finder function
may additionally include, as shown in FIGS. 27A-C and 28, a helper
icon 1205 to offer the consumer 85 an additional way to seek
information, or a tutorial, on the use of the item finder
function.
[0200] In some embodiments, a link for a tutorial on the use of the
cart 10 may be provided, along with a button or link to return to
the main menu. In some embodiments, a user may enter a question by
way of a keyboard such as that described above with respect to the
item finder function, and an answer, if one exists in a database of
frequently asked questions, may be displayed. In some embodiments,
an index of topics pertaining to frequently asked questions may be
displayed, enabling the user to select any one relevant to her
question for review.
[0201] Referring now to FIG. 29, a method is shown for navigating
the scrolling menu functions with a user interface in accordance
with embodiments of the present disclosure. The user interface
displays the scrolling menu in the first area of the available
display space (block 1700). The user interface also dynamically
displays in the second area of the available display space content
associated with a menu option in the selection position of the
scrolling menu (block 1702). The term "dynamic display" is intended
to indicate that as the scrolling menu is scrolled in any direction
(e.g., up and down for a vertical scrolling menu or right and left
for a horizontal scrolling menu), the content displayed in the
second area is changed at the same rate at which the scrolling menu
is scrolled. When each menu option (i.e., a function icon) is
within the selection position of the scrolling menu, the content
associated with that particular function is displayed, and the
instant that the function within the selection position changes
(i.e., due to movement of the scrolling menu by the user), the
content displayed in the second area is also updated.
[0202] If the user is scrolling the menu (at block 1704), the user
interface dynamically updates the content displayed in the second
area to show different content (i.e., the content associated with
the menu option presently shown in the selection position) (block
1706). As described previously, the scrolling menu may be scrolled
by the user at any rate, based on the comfort level of the user
with the media enabled shopping system.
[0203] If the user is not scrolling the menu at block 1704, then if
the user is manipulating the content associated with the menu
option in the selection position (at block 1708), the user
interface dynamically displays in the second area the result of
manipulation of the content (block 1710).
[0204] In the method described with respect to FIG. 29, one menu
option of the plurality of menu options may include the price check
function. As such, the content associated with the menu option for
the price check function dynamically displays a prompt to the user
to scan an item at the cart to determine a price for the item, and
upon detecting that an item has been scanned, dynamically displays
the result of the manipulation of the content, i.e., displays a
price for the item.
[0205] In the method described with respect to FIG. 29, one menu
option of the plurality of menu options may include the store
special function. As such, the content associated with the menu
option for the store special function dynamically displays at least
one sale item (and preferably a list of the store's regular
specials), and a price for the sale item. Upon selection of a
particular sale item by the user to view a location for the sale
item (i.e., manipulation of the content), the result of the
manipulation of the content is displayed, that is the location for
the sale item in a store map.
[0206] In the method described with respect to FIG. 29, one menu
option of the plurality of menu options may include the item finder
function. As such, the content associated with the menu option for
the item finder function dynamically displays an alphanumeric
keyboard display, enabling entry of an item name. Upon entry of
letters (resulting in dynamic display of valid combinations of the
entered letters), and listing products of the valid combinations of
the entered letters, and selection of an item from the list by the
user (i.e., manipulation of the content), the result is dynamically
displayed, that is the location for the entered and selected item
in a store map. Generating the list of products of the valid
combination of entered letters may include accessing a database of
items in the store to display each item containing each letter or
number successively entered in the alphanumeric keyboard, narrowing
the list of items contained with each letter entered.
[0207] In the method described with respect to FIG. 29, one menu
option of the plurality of menu options may include the help
function. As such, the content associated with the menu option for
the help function dynamically displays a step-by-step explanation
of use of the menu option to which the user most recently scrolled.
Alternatively, the content associated with the menu option for the
help function may display an index of topics for frequently asked
questions, and upon selection of a topic from the index (i.e.,
manipulation of the content), the result is dynamically displayed,
that is the answer to the selected topic.
[0208] With the content associated for each menu option, the user
interface may additionally display advertising associated with the
content associated with the menu option. In the sense used here,
the "associated" advertising may include advertising for an item in
the associated content (such as advertising for an item entered in
the item finder function associated content), advertising for a
competing item (such as advertising for an item that competes with
an entered in the price check function associated content), or
advertising simply relevant based on the location of the cart
within the store.
[0209] Optionally, prior to display by the user interface, the user
interface may generate a prompt to a user to perform an action,
such as a prompt to the user that instructs the user to scan a
loyalty card. Upon the user scanning a loyalty card, the plurality
of menu options available for that user to choose in the scrolling
menu may be broadened (if an advanced user), or limited (if a basic
user).
[0210] In various embodiments, a price check may be performed
locally, without accessing the store server to obtain a price for a
particular item. In such embodiments, as in earlier described
embodiments, the consumer 85 scans a product using the scanner 215.
A price database may be maintained locally in the ECM 200 of the
cart 10, such that a price check accesses the local database of
prices, rather than obtaining the price wirelessly from the store
server. Prices in the price database may be regularly updated, such
as each night, or each time a cart is placed in the cart corral, in
order for prices to stay up-to-date. Prices may alternatively be
updated in real time, by wireless downloads of price changes to the
price database at any time.
[0211] As mentioned above, the scrolling menu 1100 may include a
number of different functions, including, for example, enabling a
consumer 85 to remotely request and secure a place in a store
department's service queue. In one embodiment as shown in FIG. 30,
a consumer 85 can navigate the scrolling menu 1100 with the five
way navigation device 123 and scroll the store's deli function icon
310 into the selection position 1106. Once the deli function icon
310 has been scrolled into the selection position 1106, the content
associated with the deli function icon 310, including a request for
a queue number assignment icon 311 is displayed in some of the
remaining space visible in the video display 75. The consumer 85
may then use the five way navigation device 123 to move the
selection position 1106 from the deli function icon 310 to the
displayed content associated with the deli function icon 310 and
scroll the queue number assignment icon 311 into the selection
position 1106 and activate the queue number assignment icon 311 to
request a deli queue number 360. This would be the equivalent of
going to the deli and tearing off a paper tag to enter the deli
queue.
[0212] In an embodiment, as shown in FIG. 30, when the consumer 85
activates the queue number assignment icon 311, this authorizes the
ECM 200 to generate a queue number request signal with a cart
specific identifier 312 that is communicated to a queuing number
processor 313 via the network transceiver 204. The network
transceiver 204 is one of a number of electronic queue
number-related information receivers employed in this electronic
queuing system. Other electronic queue number-related information
receivers include a queue number request signal receiver 364, a
queue number receiver 366, and a queuing system transceiver 368.
Transmit and receive functions may be carried out by separate
components or a common component (e.g., transceiver) as will be
understood by those skilled in the art. The network transceiver 204
transfers the queue number request signal with a cart specific
identifier 312 to the queuing number processor 313 via a wireless
link between the network transceiver 204 and the queuing number
processor 313. The queue number processor 313 may generally
analogized to, or recognized as, a typical queue number dispenser
that may be found in various automotive, pharmacy, photo lab, and
deli service areas. These dispensers, like the queue number
processor 313 of the instant disclosure, may be configured to
provide hard and/or electronic notice of the queue number place
assigned to a requesting customer. Additionally, these devices may
be networked so that direct requests for queue positions, e.g.,
physically pulling a tab from a dispenser, and remote requests for
queue positions, e.g., the cart based request described below, may
be coordinated and allocated in the most efficient and customer
friendly manner. The queuing number processor 313 is configured
with a queue number request signal receiver 364 to receive the
queue number request signal with a cart specific identifier 312.
The queuing number processor 313 is also configured to generate
successive queue number signals with a cart specific identifier 365
in response to queue number request signals 312. The queuing number
processor 313 communicates the queue number signal with a cart
specific identifier 365 to the ISS 330 via the queuing number
processor transmitter 367 and the store's WLAN. The ISS 330
receives the queue number signal with a cart specific identifier
365 via its queuing system transceiver 368. The ISS 330 determines
where in the service queue to place the cart 10 associated with the
queue number request signal with a cart specific identifier 312.
The ISS 330 is configured with a queue number generator 369 for
generating a queue number 360. The ISS 330 is also configured with
a queue number provider 361 that operates to communicate the
assigned queue number 360, to the cart 10 and to the queuing number
processor 313, via the queuing system transceiver 368 and the
store's WLAN. The cart 10 receives assigned queue number 360 by way
of the network transceiver 204. The queuing number processor 313
receives the assigned queue number 360 by way of the queue number
receiver 366. When determining where in the queue to place the cart
10 associated with the queue number request signal with a cart
specific identifier 312, the ISS 330 may consider: the distance the
cart 10 has to travel to reach the service queue; the number of
requests for queue numbers, both non-remote and direct (e.g.,
walkups), over a period of time; the items contained on the
consumer's 85 shopping list that has been uploaded onto the cart
10; the loyalty or preferred status of the consumer 85; allowing
for the availability of sufficient and efficient queue numbers for
store consumer 85s choosing to directly obtain a queue number from
the service queue; and any other factors relating to placing the
cart 10 associated with the queue number signal with a cart
specific identifier 312 into the service queue, other than mere
sequential requests for queue numbers. The ISS 330 may also
generate and communicate an estimated time to service signal 362 to
the cart 10 via queuing system transceiver 368 and the store's WLAN
which is received by the cart 10 by the network transceiver 204.
The ISS 330 may also generate other queue number-related
information 363, such as the current queue number being served, and
communicate that other queue number-related information 363 to the
cart 10 via the store's WLAN which is received by the cart 10 by
the network transceiver 204.
[0213] While the above details one embodiment of the remote service
queuing functionality of the cart 10, FIG. 31 represents another
embodiment whereby the consumer 85 activates the queue number
assignment icon 311, this authorizes the ECM 200 to generate a
queue number request signal with a cart specific identifier 312
that is communicated to the ISS 330 by the network transceiver 204
via the WLAN. The network transceiver 204 is one of a number of
electronic queue number-related information receivers employed in
this electronic queuing system. Other electronic queue
number-related information receivers include a queue number request
signal receiver 364, a queue number receiver 366, and a queuing
system transceiver 368. The ISS 330 receives the queue number
request signal with a cart specific identifier 312 by way of the
queuing system transceiver 368 and utilizes the queuing system
transceiver 368 to query the queuing number processor 313 for a
queue number 360. The queuing number processor 313 is configured
with a queue number request signal receiver 364 to receive the
queue number request signal with a cart specific identifier 312.
The queuing number processor 313 is also configured with a queue
number generator 369 to generate successive queue numbers with cart
specific identifiers 322 in response to queue number request
signals 312. The queuing number processor 313 communicates a
generated queue number with a cart specific identifier 322 to the
ISS 330 via the queuing number processor transmitter 367. The ISS
330 receives the queue number with a cart specific identifier 322
by way of the queue number receiver 366. The ISS 330 is also
configured with a queue number provider 361 that operates to
communicate the assigned queue number 360 to the cart 10 via the
queuing system transceiver 368 and the store's WLAN. The ISS 330
may also generate and communicate an estimated time to service
signal 362 to the cart 10 via the store's WLAN which is received by
the cart 10 by the network transceiver 204. The ISS 330 may also
generate other queue number-related information 363, such as
current queue number being served, and communicate that other queue
number-related information 363 to the cart 10 via the store's WLAN
which is received by the cart 10 by the network transceiver
204.
[0214] FIG. 32 depicts another embodiment whereby the consumer 85
activates the queue number assignment icon 311, this authorizes the
ECM 200 to generate a queue number request signal with a cart
specific identifier 312 that is communicated to the ISS 330 via the
network transceiver 204. The network transceiver 204 is one of a
number of electronic queue number-related information receivers
employed in this electronic queuing system. Other electronic queue
number-related information receivers include a queue number request
signal receiver 364, a queue number receiver 366, and a queuing
system transceiver 368. The network transceiver 204 transfers the
queue number request signal with a cart specific identifier 312 to
the ISS 330 via a wireless link between the network transceiver 204
and the ISS 330. The ISS 330 communicates the queue number request
signal with a cart specific identifier 312 to the queuing number
processor 313 via the queuing system transceiver 368 and the
store's WLAN. The queuing number processor 313 is configured with a
queue number request signal receiver 364 to receive the queue
number request signal with a cart specific identifier 312. The
queuing number processor 313 is also configured with a queue number
signal generator 370 to generate successive queue number signals
with a cart specific identifier 321 in response to queue number
request signals 312. The queuing number processor 313 communicates
the queue number signal with a cart specific identifier 321 to the
ISS 330 via the queuing number processor transmitter 367 and the
store's WLAN. The ISS 330 receives the queue number signal with a
cart specific identifier 321 by way of the queuing system
transceiver 368. The ISS 330 determines where in the service queue
to place the cart 10 associated with the queue number signal with a
cart specific identifier 321, and utilizes the queue number
generator 369 to generate a queue number 360. When determining
where in the queue to place the cart 10 associated with the queue
number signal with a cart specific identifier 321, the ISS 330 may
consider: the distance the cart 10 has to travel to reach the
service queue; the number of requests for queue numbers, both
non-remote and direct over a period of time; the items contained on
the consumer's 85 shopping list that has been uploaded onto the
cart 10; the loyalty or preferred status of the consumer 85;
allowing for the availability of sufficient and efficient queue
numbers for store consumer 85s choosing to directly obtain a queue
number from the service queue; and any other factors relating to
placing the cart 10 associated with the queue number signal with a
cart specific identifier 321 into the service queue, other than
mere sequential requests for queue numbers. The ISS 330 is also
configured with a queue number provider 361 that operates to
communicate the assigned queue number 360, to the cart 10 and to
the queuing number processor 313, via the queuing system
transceiver 368 and the store's WLAN. The ISS 330 may also generate
and communicate an estimated time to service signal 362 to the cart
10 via the store's WLAN which is received by the cart 10 by the
network transceiver 204. The ISS 330 may also generate other queue
number-related information 363, such as the current queue number
being served, and communicate that other queue number-related
information 363 to the cart 10 via the store's WLAN which is
received by the cart 10 by the network transceiver 204.
[0215] In yet another embodiment, as shown in FIG. 33, the consumer
85 activates the queue number assignment icon 311, this authorizes
the ECM 200 to generate a queue number request signal with a cart
specific identifier 312 that is communicated to a queuing number
processor 313 via the network transceiver 204. The network
transceiver 204 is one of a number of electronic queue
number-related information receivers employed in this electronic
queuing system. Other electronic queue number-related information
receivers include a queue number request signal receiver 364 and a
queuing system transceiver 368. The network transceiver 204
transfers the queue number request signal with a cart specific
identifier 312 to the queuing number processor 313 via a wireless
link between the network transceiver 204 and the queuing number
processor 313. The queuing number processor 313 is configured with
a queue number request signal receiver 364 to receive the queue
number request signal with a cart specific identifier 312. The
queuing number processor 313 is also configured with a queue number
generator 369 to generate successive queue numbers with cart
specific identifiers 322 in response to queue number request
signals 312. The queuing number processor 313 communicates a queue
number with a cart specific identifier 322 to the ISS 330 via the
queuing number processor transmitter 367. The ISS 330 receives the
queue number with cart specific identifier 322 by way of the
queuing system transceiver 368. The ISS 330 is also configured with
a queue number provider 361 that operates to communicate the
assigned queue number 360, to the cart 10 via the queuing system
transceiver 368 and the store's WLAN. The ISS 330 may also generate
and communicate an estimated time to service signal 362 to the cart
10 via the store's WLAN which is received by the cart 10 by the
network transceiver 204. The ISS 330 may also generate other queue
number-related information 363, such as the current queue number
being served, and communicate that other queue number-related
information 363 to the cart 10 via the store's WLAN which is
received by the cart 10 by the network transceiver 204.
[0216] In an additional embodiment, as shown in FIG. 34, the
consumer 85 activates the queue number assignment icon 311, this
authorizes the ECM 200 to generate a queue number request signal
with a cart specific identifier 312 that is communicated to a
queuing number processor 313 via the network transceiver 204. The
network transceiver 204 is one of a number of electronic queue
number-related information receivers employed in this electronic
queuing system. Other electronic queue number-related information
receivers include a queue number request signal receiver 364. The
network transceiver 204 transfers the queue number request signal
with a cart specific identifier 312 to the queuing number processor
313 via a wireless link between the network transceiver 204 and the
queuing number processor 313. The queuing number processor 313 is
configured with a queue number request signal receiver 364 to
receive the queue number request signal with a cart specific
identifier 312. The queuing number processor 313 is also configured
with a queue number generator 369 to generate successive queue
numbers in response to queue number request signals 312. The
queuing number processor 313 is also configured with a queue number
provider 361 that operates to communicate the assigned queue number
360, to the cart 10 via the queuing number processor transmitter
367 and the store's WLAN. The queuing number processor 313
communicates an assigned queue number 360 to the cart 10 via the
store's WLAN which is received by the cart 10 by the network
transceiver 204. The queuing number processor 313 may also generate
and communicate an estimated time to service signal 362, or other
queue number-related information 363, such as the current queue
number being served, to the cart 10 via the queuing number
processor transmitter 367 and the store's WLAN, which is received
by the cart 10 by the network transceiver 204. In embodiments, the
queuing number processor 313 may be a stand alone component (e.g.,
a computer located in a service area), may be part of the ISS 330,
or may otherwise be integrated or networked into a local area
network within the store. In various embodiments, the queuing
number processor 313 may receive the queue number request signal,
generate a queue number, and provide the queue number to the
cart.
[0217] As shown in FIG. 35, upon receipt of the assigned queue
number 360, the ECM 200 generates a queue number indicator signal
380 and directs the video display 75 to display a queue number
indicator 381 which informs the consumer 85 of his queue number
360. As shown in FIG. 36, in response to the receipt of an
estimated time to service signal 362 the ECM 200 generates an
estimated time to service countdown timer 385 and directs the video
display 75 to display the estimated time to service countdown timer
indicator 386 which informs the consumer 85 of the estimated time
to service. As shown in FIG. 37, the ECM may also generate an
estimated time to reach the service queue timer and communicate an
estimated time to reach the service queue signal 390 to the video
display 75 directing the video display 75 to display an estimated
time to reach the service queue timer indicator 391 which informs
the consumer 85 of the estimated time to reach the service queue.
Additionally, as shown in FIG. 38, the queuing system may provide
additional information related to the service queues to the ECM
200, such as information related to the current queue number being
served 395. Upon receipt of this information, the ECM 200 may a
generate a current queue number being served signal 396 and direct
the video display 75 to display a current queue number being served
indicator 397 to inform the consumer 85 of the current queue number
being served. The information shown in FIGS. 35-38 may be shown
individually or in various combinations (e.g., sequentially or
simultaneously).
[0218] In the same manner as a position in a deli queue may be
secured, positions in a butcher queue, bakery queue, pharmacy
queue, automotive services queue, photo queue, or any other service
department queue maintained by a store may also be secured.
[0219] In an embodiment, the cart 10 is additionally operable for
various Shelf Management activities, such as, but not limited to,
taking inventory, enabling price changes, product reorganization,
restocking, returning misplaced products to the proper shelf
location, and the like. The shelf management features enabled by
use of the cart 10 are used by the retailer to electronically
manage product location and pricing in the store.
[0220] In an embodiment, the aisle RFID reader 225 with antennas
226 may also scan individual products on the shelves 301 and 302
that are labeled with individual RFID tags. In this embodiment, the
aisle RFID reader 225 with antennas 226 may scan, identify, and
count each individual product by means of the individual RFID tag,
and convey this information via the ECM 200/network transceiver 204
to other network components to be discussed herein in greater
detail below, enabling retailers to manage the store inventory to
an exacting degree of accuracy on a continuous basis. Furthermore,
all or a portion of the aisle tags 303 and 304 may be replaced via
products labeled with individual RFID tags, and the system may
otherwise function as described herein.
[0221] The aisle RFID reader 225 and antennas 226 may assist the
store management with store planograms and inventory. A planogram
is a diagram of fixtures and products that illustrates how and
where retail products should be displayed, usually on a store
shelf, bin or counter in order to influence consumer selection.
Consumer packaged goods manafacturers often release a suggested
planogram with their new product, to show how it relates to
existing products in the same category, though stores also develop
planograms of their own. Because a planogram involves the location
of products within the store, the aisle RFID reader 225 and
antennas 226 can detect the location of products at the Stock
Keeping Unit ("SKU") level. Many inventory management systems
assign a unique SKU for each product and also for its variants, and
SKUs are assigned and serialized at the merchant level.
[0222] In use, when a cart 10 is moved through the store, the aisle
RFID reader 225 and antennas 226 scan the SKU assigned to product
lines or product bundles on the shelves 301 and 302 that are
labeled with individual RFID tags, each RFID tag being associated
with a SKU. In this embodiment, the aisle RFID reader 225 with
antennas 226 may scan, identify, and locate each product line or
bundle by means of the RFID tag, and convey this information via
the ECM 200/network transceiver 204 to other network components to
be discussed herein in greater detail below, enabling retailers to
locate products throughout the store to manage, update and design
the store planogram in an efficient and consistent manner.
[0223] The cart 10 enables re-mapping of the store. As discussed
above, taking the cart 10 through various paths in the store
following rearrangement of products will result in the cart 10
reading the RFID tags (e.g., SKU and/or product level tags) marking
the new locations of each moved product relative to the anchor RFID
tags (e.g., shelf level tags that have not moved), and convey the
new locations to the system, such that the location of products in
the store readily updated in relationship to the base store
map.
[0224] Additionally, the cart 10 enables inventory that may be
performed on an on-going basis with real-time updates for stores
that sell products identified at the product level by an RFID tag.
When any cart 10 reads no product level RFID tags at a location
(marked by an anchor) where products are expected to be, the cart
10 may convey this information to the store system to update the
inventory for the products that are no longer filling the shelves
where expected. This allows real-time product inventory and
restocking.
[0225] An employee is enabled by the cart 10 to quickly reshelve
products that are misplaced, such as when a consumer decides not to
purchase a product and leaves it at the Point of Purchase or in a
location other than where the product is shelved. By using the
shelf management system of the cart 10, the employee may scan the
misplaced product, and according the map, be directed to the
location in the store where the scanned product is supposed to be
shelved. The employee may even confirm that he or she is putting
the product back in the appropriate location by scanning the
sticker located on the shelf, because the sticker, usually with a
price indicated, is associated with a specific location for a
specific product.
[0226] When the store implements price changes for a list of
products, an employee or group of employees usually must go around
the store, find all the products with changed prices, and swap out
signs and labels, which can be a time consuming task that occurs at
regular intervals (e.g., weekly specials). The cart 10 enables an
efficient process for dynamically changing prices for products
accurately and quickly.
[0227] Specifically, for the price change process enabled by the
cart 10, price changes, such as for weekly specials and the like,
are entered in a database of prices in the store system. An
employee may then use a cart in shelf management mode to go
throughout the store to change labels. A battery powered, wireless
printer may be placed in the cart 10, such as in the child seat 60,
and operably coupled (e.g., wired or wireless, such as Bluetooth,
wi-fi, or infra red) to the ECM 200 for printing new price labels
when the cart is located in the right location for a given product.
The employee identifies himself or herself to the cart 10 by
scanning an employee badge, much like scanning a loyalty card, that
enables access to the shelf management features unavailable to
consumers. The price changes entered into the database are conveyed
to the cart's ECM 200 from the store system. Based on known
locations of the products listed, the cart 10 displays to the
employee a map, as shown in the view of FIG. 22. The view of FIG.
22 shows the list of products for which a price change is being
implemented, a location of each product on the list, the old price,
the new price, and permits the employee to check a product off the
list once the price has been changed.
[0228] The employee moves the cart to the location of a product on
the list, and when the employee has found the location of the
product, he or she may scan one item of the product to confirm that
the shelf location is actually the right shelf location for the
product on the list. Once the location is confirmed as correct for
the product, the employee prints a new label on the wireless
printer placed in the cart, and places the new label with the new
price over the old label with the old price on the shelf. Once the
new label is in place, the employee checks the product off the
list, and the cart 10 conveys to the store system that the price
change has been implemented at the shelf level. The store system
may then charge the new price at the Point of Purchase, thereby
allow real-time pricing updates.
[0229] In a large store, or in a store holding many specials such
as for a holiday weekend, the process of updating for price changes
is greatly sped up using one or more carts 10 as discussed herein.
Additionally, the price changes are dynamic, in that they take
effect as soon as a new price label is in place on the shelf. With
the scanning ability of the cart 10 to confirm that the new price
label is being placed in the proper location, price changes are
also more accurate than relying on any given employee's knowledge
of product placement within the store.
[0230] As the consumer checks out (i.e. renders payment) at the
Point of Sale 300, the POS computer 326 (e.g., computerized
register) or POS server 325 may record the purchases made by that
consumer 85 using that particular cart 10. The POS computer 326,
the POS server 325, and other systems such as security systems or
consumer loyalty systems may be referred to generically as retailer
systems. Retailer systems provide automated, computerized services
with respect to consumer or store needs. In an embodiment, retailer
systems may comprise components of the overall store network. In an
embodiment, retailer systems may be stand-alone functional units
operating separately from the store network. In an embodiment, a
retailer system may comprise a point of sale system to interact
with individual carts or consumers for processing payment at the
conclusion of a shopping trip. In an embodiment, a retailer system
may comprise a consumer loyalty system for rewarding consumer
loyalty with discounts and other advantages, while tracking
shopping history for advertising purpose. In an embodiment, a
retailer system may comprise a security system for tracking the
location of carts within the store or areas outside the store, such
as, for example, alerting the store management to the location of
carts when abandoned or broken, whether carts have left the store
premises or when carts remain in the parking lot to be returned to
the store.
[0231] In an embodiment, the cart 10 includes a cart RFID tag that
may be read by a POS RFID reader coupled to the POS server computer
326 or POS server 325. The cart RFID tag may be located anywhere on
the cart, and in an embodiment is located on or in video display
75, for example in the screen housing 92, 93. In an embodiment, the
cart RFID tag is located on or in the video display 75 along with
the network transceiver 204. The POS RFID reader may read the cart
RFID tag, thereby identifying a specific cart, for example via the
cart RFID tag associated with a serial or identification number.
Alternatively, the POS system may use a bar code scanner to scan a
bar code on the particular cart that uniquely identifies the cart
and correlate the bar code with the serial or identification
number. Alternatively, the particular cart may be identified and
correlated manually at the POS, for example via entry of the serial
or identification number labeled on the cart into the POS computer
326. The information obtained, both by checkout (e.g., via bar code
and/or basket RFID scanning) and/or by the cart 10 during shopping
(e.g., via bar code and/or basket RFID scanning), may be correlated
to a particular cart (based on the cart's unique identity) and/or
transferred to the ISS 330 and the Host Central Server 340. Such
correlation may occur anonymously, for example, without reference
to the identity of the consumer. Such information may further be
correlated with a specific consumer, for example via scan or entry
of a loyalty card, a pin code, a telephone number, or other
consumer identifier. Such information may further be correlated
with specific advertising displayed during the particular use of
the shopping cart.
[0232] The basket RFID reader 227 in conjunction with the ECM 200
may have identified and stored the identity of each product placed
in the cart 10 during shopping, such that upon approaching the
Point of Sale 300, the POS computer 326 may initiate checkout
services based on the products for purchase known to be in the cart
10 by the ECM 200, as communicated to the POS computer 326 via the
network transceiver 204. Thus, the RFID enablement of the shopping
cart and the application of RFID tags at the individual product
level will facilitate the shopper's Point of Sale checkout
efficiency. Alternatively, the consumer 85 may use the scanner 215
to scan each product placed in the basket, such that upon
approaching the Point of Sale 300, the POS computer 326 may
initiate checkout services based on the products for purchase known
the be in the cart 10 by the ECM 200, as communicated to the POS
computer 326 via the network transceiver 204.
[0233] In various embodiments, certain features may be additionally
available at the Point of Sale. In one embodiment, the cart
maintains a running total for items for purchase by the consumer 85
(i.e., the inventory of the cart). The total may be conveyed from
the cart to the Point of Sale computer, and confirmed by the
consumer 85 for completing the purchase transaction without
requiring the inventory of the cart to be scanned over again at the
Point of Sale. Upon displaying the cart total from the cart on the
Point of Sale computer, the consumer 85 verifies that the amount is
accurate, and completes the transaction (i.e., swipes a credit or
debit card, completes her check or provides a sufficient amount of
cash).
[0234] In other embodiments, at the Point of Sale, the actual cart
weight for the inventory of the cart is measured and compared for
example to the known, expected weight for the inventory of the
cart. Specifically, the cart and the contents are weight and
compared to the weight for the cart that is known, and the weight
for the contents, known based on the inventory of the cart. A
difference between the actual cart weight for the inventory and the
known, expected weight indicates a potential problem of theft, and
may generate an alert to the store server and/or an employee.
[0235] Implementing the improvements described herein, an assisted
self-checkout may be performed at a "regular" checkout lane (i.e.,
a Point of Sale computer equipped for purchase transaction). The
consumer 85 proceeds with a shopping trip, scanning items for
purchase as she goes, and placing the items in her cart. Upon her
approach to the Point of Sale, the ECM 200 on her cart communicates
the cart inventory and total from the cart to the Point of Sale
computer. When consumer's 85 turn comes to complete the purchase
transaction, the consumer's 85 cart 10 and its contents are
weighed. In various embodiments, the cart or an employee may
instruct the consumer 85 to remove personal items such as a
handbag, as well as any child present in the child seat, in order
for an accurate measurement of the weight of the cart and its
contents. The actual weight of the cart and its contents are
compared to the known, expected weight for the cart and the
contents: the weight of the contents is calculated based on known
weights for each item sold in the store and the inventory of the
cart communicated when the consumer 85 approached the Point of
Sale. If the actual weight exceeds the known, expected weight, an
alert may be generated to notify store security or a store employee
to assist the consumer 85 with removing personal items that should
not have been included in the actual weight. In various
embodiments, the alert is only generated if the weight difference
exceeds a predetermined threshold amount.
[0236] Upon confirmation of the actual weight relative to the
known, expected weight, the Point of Sale computer displays the
cart total to the consumer 85 for verification. In an embodiment,
the Point of Sale computer asks the consumer 85 "Does the total
below equal the total for your cart? If so, press 1, and if not,
press 2 for assistance." When the consumer 85 selects "2" if the
total does not equal the cart total, a store employee may assist in
finalizing the purchase, while when the consumer 85 selects "1,"
the Point of Sale computer further prompts the consumer 85 to
complete the purchase transaction using her preferred method of
payment (i.e., a credit card, check, cash, or debit account
associated with consumer). The Point of Sale computer accepts the
consumer 85's payment, provides any cash back requested by the
consumer 85, and the transaction is complete. In embodiments, the
entire purchase transaction from the time the consumer 85 enters
the Point of Sale transaction is limited only to the amount of time
necessary for the consumer 85 to carry out her payment option, with
only negligible time used to weigh the cart and contents for
comparison and verify the cart total.
[0237] In use, the consumer 85 may also use the cart for services
that in the related art would require the consumer to find a store
employee. Via voice commands delivered to the voice activated
interface 120 operably coupled to the ECM 200 and the in-store
network, the consumer 85 may request the location of a specific
product or request information pertaining to a particular product
such as nutritional information, whether any specials for that
product are available, and recipes that may incorporate a product.
By activating the voice activated interface 120 by way of the five
way navigation device 123, the consumer 85 may also contact various
in-store services, such as a pharmacy, deli counter, or automotive
service station to initiate an order or check on the status of
their order. The consumer 85 may additionally contact customer
services within the store without waiting in line at a counter, by
calling the customer service desk from the voice activated
interface, enabling activities such as requesting a rain check or
reporting a safety hazard in the store. In other embodiments, the
consumer 85 may use the voice activated interface as a means of
calling a person or service outside of the store, by using the ECM
200's communication abilities to connect to the Internet, enabling
Voice Over Internet Protocol ("VoIP") technology. For example, a
consumer 85 may wish to check with their spouse regarding which
product to buy or for shopping list products, and may use the VoIP
enablement and voice activated interface 120 to call home.
[0238] Another in-store use is the bar-code scanning. A consumer 85
may choose to scan their own products with the scanner 215 inset
into the handle 22 or pod 150, enabling him to view a running total
for the products in the cart 10 for purchase. By scanning the
products during the shopping trip using the scanner 215, the
scanner 215 enables the consumer 85 to avoid waiting in the
checkout lanes, as the ECM 200 may communicate the products being
purchased, the price of each product, and the running total, as
well as the value of any coupons used and scanned by the consumer
85 to the POS computer 326 upon arriving at the Point of Sale 300.
Bar-code scanning during shopping, in conjunction with the cart 10
communicating the scanned inventory to the Point of Sale 300,
facilitates more efficient check out services for consumers.
[0239] In addition to the voice activated interface 120, the
consumer 85 may use a number of the media enhancements of the cart
10 via the five way navigation device inset in the handle 22 or pod
150. The consumer may press the voice activation button 122 (which
preferably is a center button of the five way navigation device
123) to activate the voice recognition system as well as to
navigate other applications to access certain functions and
information on the cart 10 such as product location and other
product information. The five way navigation device 123 may be used
to maneuver through the menu of options 124 displayed on the video
display 75.
[0240] As the cart supports voice recognition and additionally
connects to the store server wirelessly (and thereby a connection
to the Internet is provided to the cart), the cart may be enabled
for communication via VoIP. VoIP on the cart offers the ability to
call, for example, customer service within the store (for example,
to report a spill or ask for assistance), store personnel (i.e. to
reach the store manager for a complaint or compliment), and between
carts (e.g., for store employees to use in set up, inventory, and
the like). In one embodiment, a "call" icon may be provided on the
screen of the cart. The user may select the icon either by a voice
command or using the five way navigation device, and communicate
via VoIP using the wireless internet to the store server, which is
tied in turn to the customer service desk or the Internet generally
to communicate by VoIP with individuals outside of the store (e.g.,
call home to check for an ingredient).
[0241] With the media enhancements, a consumer 85 will have the
capability to formulate a shopping list at home on the Internet,
forward the list to the store via email, and upon registering with
a cart 10 with a loyalty card or other consumer identifier in the
store, have their shopping list displayed on the video display 75
and be guided through the store in aisle and product order, showing
specials, promotions, and product location for products on their
shopping list.
[0242] In various embodiments, the cart provides the consumer 85
with shopper features to enhance the shopping experience. In one
shopper feature, the consumer 85 is enabled to save and name
shopping lists. In one embodiment, saving and naming shopping lists
may be performed from a web site, while in other embodiments,
saving and naming shopping lists may be performed directly on the
cart. In further embodiments, saving and naming shopping lists may
be performed on a mobile device, such as a handheld computer, a
Blackberry.TM., or a mobile telephone, and transferred to the cart
wirelessly, by infrared, or by Bluetooth.TM. enabled technology.
Saved shopping lists may be tied to a user identifier, and
retrieved upon scanning a loyalty card or other identifying
card.
[0243] In some embodiments, an additional shopper feature provides
a course directing the consumer 85 to each item on the shopping
list. A shopping list that comprises, for example, a wedding or
baby registry, may include a course providing directions for the
consumer 85 to find each item on the list within the store,
enabling faster and easier identification of list items for
purchase. In various embodiments, the course may be displayed in a
graphical representation of the store. In various other
embodiments, the course may be generated by displaying at the top
of the shopping list the items from the list closest in proximity
and in the direction in which the cart is moving, constantly
updated as the cart moves.
[0244] In another shopper feature, the consumer 85 is enabled to
email a recipe or a link to a vendor's web site with a recipe to an
email address. The email address may include an email address on
file or an email address entered on the cart. In various
embodiments, the email address is verified before sending.
[0245] In another shopper feature, the consumer 85 is enabled to
scan and use coupons at the cart, such that the cart total
accurately reflects the price discount provided by the coupons
during the shopping trip. In such embodiments, the amount of
savings for coupons, and identity of coupons and products for which
the coupons are used are conveyed to the Point of Sale
computer.
[0246] In another shopper feature, a folder of personalized
reminders for the consumer 85 is stored. As with the shopping
lists, the folder of personalized reminders may be tied to a user
identifier, and retrieved upon scanning a loyalty card or other
identifying card. Personalized reminders may include greeting card
reminders for birthdays, anniversaries, and other holidays.
Personalized reminders may additionally include prescription
reminders for an in-store pharmacy. In various embodiments, when a
reminder is generated by the cart to alert the consumer 85 with a
prescription reminder, the consumer 85 may select the reminder to
automatically place the prescription order (i.e., refill) with the
in-store pharmacy, and another alert may be provided to the
consumer 85 via the cart when the prescription order is ready to be
picked up. Other personalized reminders may also be available, such
as monthly refills for standard pantry items, pet items, and the
like.
[0247] In various embodiments, any saved personalized items, such
as lists or reminders, may be uploaded to the enterprise server,
enabling the consumer 85 to access the items in the premises of any
retailer that employs the overall system, making the items portable
from retailer to retailer, assisting with comparison shopping and
easier use of lists without the consumer 85 having to maintain
different lists for the various stores where she shops.
Furthermore, stored items may be automatically updated in real time
when the consumer 85 makes additions or changes.
[0248] The cart 10, by way of the media enhancements discussed
above captures real-time purchasing behavior at the individual
consumer level and provides back end data mining and analytical
reporting. The cart 10 captures information that is specific down
to the second about the cart 10 and a consumer's movement and
interactions with the cart, and records it for use by retailers and
advertisers. For example, consumer shopping patterns may be
collected, anonymously if preferred by the consumer, for analysis
and use by advertisers, consumer goods manufacturers, and
retailers. Retailers may use the cart information for store
operations, as discussed herein with respect to shelf management.
Additionally, service and maintenance information provides timely
information to cart maintenance personnel regarding cart usage and
problems.
[0249] In an embodiment, when the consumer 85 brings the cart 10 to
the Point of Sale 300 at the conclusion of the shopping trip, the
ECM 200 may communicate data to the ISS 330, a POS server 325, a
POS computer 326, or combinations thereof. In an embodiment, the
ECM 200 communicates with ISS 330, which in turn communicates with
POS server 325, which in turn communicates with POS computer 326,
and vice-versa. Typically, the POS server 325 and the POS computer
326 are part of an existing local area network in a given store,
and the ISS 330 typically would be added as a new component to the
existing local area network upon implementation of the media
enabled shopping cart at a particular location. While not required,
communication with the ECM 200 may be facilitated by directing such
communication through the ISS 330, rather than directly with ECM
200.
[0250] In an embodiment, the cart 10 communicates the identity of
the products being purchased to the POS computer 326 or POS server
325 via the ISS 330, as the identity of each product was obtained
during shopping when the consumer 85 scanned the product with the
scanner 215 or the basket RFID reader 227 identified the product
when it was placed in the cart 10. Alternatively, the POS computer
326 or POS server 325 may obtain the identity of the products being
purchased by the consumer 85 or a store employee scanning the bar
code on each product at the Point of Sale 300.
[0251] As the consumer checks out (i.e. renders payment) at the
Point of Sale 300, the POS computer 326 or POS server 325 may
record the purchases made by that consumer 85 using that particular
cart 10 as described herein. The information obtained, both by
checkout and by the cart 10 during shopping, may be transferred
to/from the ISS 330 and/or the Host Central Server 340. Using data
mining advances enabled by the cart 10 and its media enhancements,
advertisers can individually track the effectiveness of advertising
and pricing campaigns without compromising the personal identity of
the consumer, alleviating privacy concerns of consumer groups.
Alternatively, the information can be correlated to a specific
consumer, for example via a loyalty card program, where the
consumer is agreeable to such.
[0252] The data communicated by the ECM 200 may include data
programmed to its memory, or data collected and stored in the
memory over the course of the consumer's 85 shopping trips
(initiated when the consumer 85 first moved the cart 10). In an
embodiment, such data may include any of the following: 1) the
identity of the cart, 2) where in the store the cart has been, 3)
which advertisements have been displayed to the consumer using the
cart, 4) the length of time spent with each advertisement displayed
and the length of time spent in specific areas or aisles of the
store, 5) what products are in the cart 10 for purchase, 6) if
known (such as from a loyalty card), consumer statistical or
demographic data (gender, age, spending and purchasing habits), 7)
store traffic patterns such as time, day, period, duration, etc.,
and 8) cart usage patterns (e.g., number used, typical user,
functions accessed, etc.). Such data may be correlated to determine
the effectiveness of advertising presented via the media enable
cart to the consumer at the point of purchase (i.e., proximate the
point in time when the consumer is selecting a particular product
to be placed in the basket and purchased).
[0253] In another embodiment, data includes (I) information
captured by the media cart system such as (1) cart specific data
such as (a) cart identification, (b) date and time of shopping
episode and each activity therein, (c) media cart/retailer user
card UPC scanned by a greeter at the time the cart is handed to the
shopper and scanned again by the shopper at checkout, at which time
the card is returned to the store for use by another consumer 85,
which helps to link information captured by the media cart system
with POS data,
[0254] (d) cart tracking such as location and duration, and (e)
cart activities such as product locator, price checks, shopping
lists, basket views such as totals, UPC, number of items, etc; and
(2) consumer campaigns, ads, promotions such as description of
ad/promo, ad/promo reference number, campaign name and reference
number, ad/promo start/stop time, ad/promo trigger variables (e.g.,
location, time, loyalty, non-loyalty), and location in store; (2)
Point of Sale (POS) data such as (a) media cart/retailer user card
UPC scanned by a greeter at the time the cart is handed to the
shopper and scanned again by the shopper at checkout, at which time
the card is returned to the store for use by another consumer 85,
which helps to link information captured by the media cart system
with POS data, (b) product description including UPC code and
manufacturer code, (c) regular product price, (d) purchased product
price, (e) basket total, (f) number of items in basket, and (g)
check-out lane number with time and date of check-out and
transaction log number; (3) Loyalty club data such as (a) loyalty
card number, (b) zip code, (c) loyalty shopper purchasing data such
as items in basket and size of basket in dollars; and (4) store
data such as (a) store address, (b) TDLinx code, (c) latitude and
longitude coordinates, and (d) store demographic data such as
number of adults/children in household, income bracket, age
bracket, ethnic group, home owner or renter, education level,
etc.
[0255] Such data may be used to product a variety of reports such
as (1) shopper segmentation data such as (a) trip size, (b) trip
duration, (c) day of week, and (d) time of day; (2) consumer
campaign studies such as (a) item purchased, including display
location and shelf location, (b) cross-purchase studies, including
whether usage idea resulted in brand purchased or other brand
purchased, (c) recipe ideas, including whether same resulted in
brand purchased or other brand purchased, (d) basket analysis,
including trip size impact, category linkage of basket, categories
absent from basket, (e) cart tracking of anonymous shopper
including types of shopping patterns (day of week, time of day, and
duration of shopping episode), perimeter areas visited (duration at
perimeter department and items scanned), aisles shopped (duration
within aisle and items scanned), displays shopped (duration at
display and items scanned), location data inquiries by shopper,
nutrition information inquiries by shopper, product pricing
inquires made by shopper, replacement of product entries, out of
store coupons used, in store coupons used; and (f) loyalty card
shopper tracking including types of shopping patterns (day of week,
time of day, and duration of shopping episode), perimeter areas
visited (duration at perimeter department and items scanned),
aisles shopped (duration within aisle and items scanned), displays
shopped (duration at display and items scanned), location data
inquiries by shopper, nutrition information inquiries by shopper,
product pricing inquires made by shopper, replacement of product
entries, out of store coupons used, in store coupons used.
[0256] Such data may also be used for analytical analysis such as
(1) location of cart including (a) verification of scanned items,
(b) verification of cart after ad stimulus such as whether the cart
moved after the ad, whether the shopper purchased the product, and
if so when, whether shopper purchased a competing product, and if
so comparative data such as price, brand quality, etc., (2) ad
viewed in product display location, including verification of
scanned item, quantity purchased, and duration of time at display
prior to cart moving, (3) ad viewed in cross-usage category
including (a) verification of scanned complimentary usage item and
(b) verification of promoted brand in ad with usage occasion, for
example whether cart moved to featured product location, and (4)
whether shopper used product locator feature to find a product in
the store, for example a complimentary or featured item.
[0257] In particular advertising data may be correlated or
integrated with sales data to determine the effectiveness of the ad
on an anonymous purchaser, or alternatively on an identifiable
consumer such as via further correlation of data provided via a
loyalty program. Where the consumer is identified, purchasing data
may be tracked over time to determine the effectiveness of
advertising and to determine whether additional and/or modified
advertising is desired. Such correlations may further provide a
wealth of useful data such purchasing patterns based upon consumer
demographics; geographic or regional preferences or variations;
product placement; ad content, style, timing, etc. For example,
reports could be generated indicating store traffic patterns; ad
impact; product volume, market share by consumer
85/household/group/store/region, repeat purchases, etc.; consumer
purchasing trends (products, dollar amounts, etc.); average size
and content of total purchase per time, day, season, etc.;
purchases by product category or segment, household, store, region,
etc.; consumer survey results; etc.
[0258] The data mining capabilities of the media enhanced cart 10
described herein enable access to metrics unique to advertising as
used in conjunction with the media enhanced cart 10. The
communications features of the cart 10 enable advertisers to
remotely download to the ISS 330 (and subsequently to each cart 10,
in some embodiments) changes in advertising. Changes in advertising
may be made in response to information obtained through data
mining, as discussed herein. The media enhancements described
herein enable advertisers to test advertisements in various
demographic or geographic groups, and see the effectiveness in an
immediate fashion, in that new statistical data is continuously
being generated and reported. Such advertising may then be modified
as needed and/or rolled out on in a large scale campaign.
[0259] The media enabled shopping cart system described herein
provides a number of advantageous features including the ability to
(a) target anonymous consumers with specific product promotions and
information at the exact point of purchase and product selection in
a retail store aisle; (b) provide specific promotions to loyalty
card consumer 85s who have opted into the program; (c) provide
shopping enhancement tools to the shopper such as store specials,
electronic shopping lists, in-store product locator, recipes,
nutritional information, and the ability to self scan products to
speed checkout; (d) capture cart traffic patterns, cart purchases,
interactions with the cart, (e) capture loyalty card consumer
shopping and purchasing behavior who have opted into the program,
(f) provide precise data mining and analytical reporting, (g)
provide retailers with shelf management system to electronically
manage product location and pricing in the store, and (h) modify
shopper traffic patterns, for example redirecting consumers to low
traffic aisles and/or to high margin products.
[0260] Referring to FIGS. 4 and 17, the cart 10 may receive
Wireless Local Area Network ("WLAN") signals including video
streams in 802.11x format. In an embodiment, a plurality of
wireless access points 320 may be located throughout the store to
provide network coverage to each cart 10 located in the store,
communicating by way of the network transceiver 204 (e.g., a
wireless modem) in ECM 200. The network transceiver 204 may be
located anywhere on cart 10 and is operably coupled to ECM 200. In
an embodiment, the network transceiver is integrated with display
75, or alternatively is integrated with ECM 200. Data may be
transferred to and from the cart 10 via the wireless link between
the network transceiver 204 and the POS Server 325. Data may be
transferred to and from the cart 10 via the wireless link between
the network transceiver 204 and the ISS 330. The ISS 330 may store
cart 10 data and act as an intermediary between the retailer's
store systems and each cart 10. The ISS 330 may also connect over a
firewall 332 through a broadband modem/router 333 via a network (in
an embodiment, the Internet or VPN 335) to a Host Central Server
("HCS") 340 located at a host company's hosting facility.
Advertising data and media may be transferred at regular intervals,
such as daily, between each store's ISS 330 and the HCS 340. Data
transferred from each store's ISS 330 may be processed by the host
company. In an embodiment, both the ISS 330 and HCS 340 utilize
standard Microsoft server configurations or equivalents thereof
along with supporting database management tools.
[0261] The Cart Explorer is an application that runs on the store
server that is responsible for keeping track of all of the carts in
the store. The Cart Explorer functions similar to Windows Explorer
for keeping track of computers in a network or other system browser
technology. The Cart Explorer maintains a status of each cart (e.g.
systems, processes, etc.) in the fleet via the wireless connection
to each cart: the health of each cart, the software version running
on each cart, disk space cart has available, the location of each
cart, the charging status, and the like. The Cart Explorer enables
an individual (such as a trouble shooting employee or an employee
trained in the setup and use of the overall system) to find and
control each cart remotely, thereby keeping a store running while
performing preventative and proactive maintenance. The individual
may employ the Cart Explorer to display a selectable icon
representing each cart in the fleet, such that when selected, a
detailed cart status is magnified. The cart status may include an
indication of battery life remaining, an indication of damage
detected, and an indication of data corruption. The cart status may
also include an indication of a present operating system, an
indication of present displayable content, and an indication of a
version of each supplemental executable program. The cart status
may further include a graphical representation of the location of
the cart in a store map.
[0262] In various embodiments, the Cart Explorer further includes a
Cart Pager system. The Cart Pager system allows a particular cart
or group of carts to be identified or notified from within an
entire pool or fleet of carts. In one embodiment, when a cart is
paged from the Cart Explorer, the cart issues an audible page
alert, such as a beep. In another embodiment, when a cart is paged
from the Cart Explorer, the cart displays a visible page alert,
such as a message appearing on the cart screen to notify a user. In
various embodiments, the Cart Explorer Cart Pager system may be
used to issue a page to just one cart, or all carts in the store.
In various embodiments, the Cart Explorer Cart Pager system may be
used to issue a page to the computer interface, or to the human
interface (i.e., the screen). In various embodiments, the Cart
Explorer Cart Pager system may include one way paging or two way
paging.
[0263] In an embodiment, the host company is a parent company for a
plurality of retail merchant stores which are networked as
described herein. An advertising company or product manufacturer
may be granted access to the HCS such that product advertising may
be remotely and centrally downloaded to the host company for
further dissemination to the various individual stores. Likewise,
information such as product information, inventory, advertising
effectiveness, etc. may be accessed from the HSC and uploaded by
the advertising company or product manufacturer. In this way, an
advertising company or product manufacturer may have a centralized
access point for the upload and download of advertising or other
product data, thereby allowing real-time access and adjustment to
business activities based upon the effectiveness of a particular
activity. For example, a new advertising campaign can be downloaded
remotely to the HCS, disseminated on a large scale or small scale
(e.g., a pilot run), and the results of the advertising campaign
can be closely monitored in real or about real-time to determine if
any adjustments need to be made.
[0264] The HCS server is operable to coordinate activity between
all the various stores, keeping track of all the data from between
stores. In various embodiments, a plurality of HCS servers may be
implemented. In various embodiments, an HCS server may be dedicated
to a particular chain of stores that are commonly controlled. The
HCS server manages all data going to the carts (i.e., digital
content management, passing ads, recipes, nutritional information,
and the like to carts through stores) as well as all the data
coming back from the carts (i.e., coordination of shop events). The
HCS server keeps track of campaigns, banners, and subcategories for
product placement and advertising, as well as the placement of ads
and/or content according to Neilson-like categories or retailer
defined categories.
[0265] In an embodiment, the operating system software of the ISS
330 may be based primarily on the Windows Server 2003 Operating
System, IIS 6.0 utilizing the .NET Compact Framework, COM+. In an
embodiment, the operating system software of the POS Server 325 may
be based primarily on the Windows Server 2003 Operating System, IIS
6.0 utilizing the .NET Compact Framework, COM+. It should be

[0266] In an embodiment, the HCS 340 may comprise one or more of
each of the following: a media server, a web server, and a database
server. In an embodiment, the one or more media servers may operate
on operating system software based primarily on Windows Server 2003
with a DivX Encoder, Media Windows Server, Flash Communications
Server, and FTP Service. In an embodiment, the one or more web
servers may operate on the operating system software based
primarily on the Windows Server 2003 Operating System, IIS 6.0
utilizing the .NET Compact Framework, COM+. In an embodiment, the
one or more database servers may operate on the operating system
software based primarily on the Windows Server 2003, IIS 6.0 .NET
Framework, COM+, SQL Server 2003 (cluster), MS SQLServer 2003, and
MS SQLServer 2005. It should be understood that specific computing
equipment and software are disclosed herein as non-limiting
examples, and that equivalent or improved components may be
substituted as such become available.
[0267] In an embodiment, various components of the system described
herein may be located commonly, for example affixed to or
integrated with the cart 10. In an embodiment, various components
of the system described herein may be distributed or dispersed over
the system as a whole while operably coupled to one another to
achieve the functions described herein, for example with one or
more components located on the cart and one or more components
located on a computing system such as a retailer's POS system, a
LAN, a WAN, etc. Likewise, various components, subsystems, and the
like as described herein may be implemented in software, hardware,
or both and operable coupled within the system as a whole to
perform their intended function as will be readily apparent to
those skilled in the art.
[0268] Methods enabled by the present disclosure include mounting a
display on a shopping cart basket as well as performing steps to
make or carry out all other attachments, configurations, and
embodiments described herein. Further, methods of use of a shopping
cart having a basket mounted video display will be readily apparent

including data mining, will be readily apparent from the present
disclosure.
[0269] In embodiment as shown in the Figures, a cart 10 is provided
having a video display 75 mounted on the nose 45 of the cart 10.
The cart 10 is further enhanced by the addition of a ECM 200, a
voice activated interface 120, a scanner 215, a five-way navigation
device, 123, a nose bumper handle 100, an aisle RFID reader 225
with antennas 226 (looking outward from the cart 10), optionally a
basket RFID reader 227 with antennas 228 (looking inward on the
contents of the basket 20), and battery charger contact plates 105
or 230, 231. The voice activated interface 120, the five-way
navigation device 123, and the scanner 215 are grouped in a pod 150
near the center of the handle 22, as shown in FIG. 19. In an
embodiment, the voice activated interface 120 further comprises a
push to talk voice activated interface having a hard or soft button
on the pod 150 or handle 22 to push to activate the voice
recognition feature. The push to talk button may be a dedicated
button or may be one or a combination/sequence of buttons, for
example on the five-way navigation device 123. The pod 150 and/or
handle 22 may further comprise a price check button, which may be a
hard or soft button. Likewise, the price check button may be a
dedicated button or may be one or a combination/sequence of
buttons, for example on the five-way navigation device 123. Pushing
the price check button allows a consumer 85 to scan an item to
determine its price, whereby the item is not added to the basket
inventory or shopping total for the consumer 85. It should be
understood that any components described herein as residing in or
on the handle 22 can likewise be integrated into the pod 150, and
in an embodiment all functional components positioned on the handle
22 are incorporated into the pod 150. The aisle RFID reader 225 is
integrated with the ECM 200 and antennas 226 are located on either
side of the housing 199 of the ECM 200. The basket RFID reader 227
may be part of ECM 200 with antennas 228 located in the base 76.
The battery charger contact plates are positioned and configured as
shown in FIGS. 6, 7, and/or 12.
[0270] More specifically, the base 76 is mounted to the inside of
front side wall 28 and conforms to the shape of the nose, for
example slightly curved as shown. As shown in FIG. 19, the base 76
may extend downward from the front edge 29 along the inside of
front side wall 28 and taper downward with the lower edge 83 of the
base contacting or about contacting the upper portion of the bottom
21 of basket 20. A base 76 as shown in FIG. 19 forms a conduit for
communication cables, power cords, etc. from the ECM 200 and/or
battery. Such conduit may further extend under the lower edge of
the bottom 21 of basket 20, and may connect with the ECM 200
housing 199. In an embodiment the conduit and/or base 76 may be
integral with the basket 20, for example molded in plastic.
[0271] The video display 75 is attached to the basket 20 such that
the viewable area 78 is above the interior 54 of the basket.
Likewise, the video display 75 is attached to the basket 20 such
that the viewable area 78 is in a field of vision 84 of a consumer
85 pushing the cart 10 via the handle 22. The video display 75 is
foldable, and the hinge 79 is positioned about equal to the front
edge 29 of the basket 20. The bottom edge 82 of the screen 77 is
positioned about equal to the front edge 29, and in some
embodiments may rest upon the front edge 29 to provide additional
support to the screen 77. For example, the outer bottom edges 98,
99 may rest on the front or side upper edges for additional
support. As shown in FIG. 2, the nose 45 and upper edges may be
slightly curved and the bottom edge 82 of screen 77 may be less
curved such that the outer bottom edges 98, 99 engage one or more
of the upper edges in an unfolded position. In a folded position as
shown in FIGS. 5 and 6, the screen extends at about a 90 degree
angle with respect to the base 76 (or alternatively extends within
the plane defining the upper edges of the cart), which clears the
nose and exterior of the cart for nesting with a second cart while
also keeping the interior 54 of the cart clear such that the rear
side wall 31 may swing upward into the interior 54 of the basket to
receive the front side wall 28 of a third cart.
