Object recognition toys and games
Abstract
A toy or game play apparatus or method involving a powered host
or master unit which operates interactively with one or more
nonself-powered play objects. The host has a preprogrammed
microcontroller and an RFID reader/interrogator circuit. Each play
object has a RFID tag IC. When the host and a play object are
positioned so as to afford RF communication between them, the host
sends power to energize the tag IC of the play object. This causes
the tag IC to transmit data back to the host. The host recognizes
that transmitted data and makes a presentation to the user caused
by that transmitted data. Some or even all of the presentation may
be the data from the play object.

Description
[0001] This application claims priority of copending U.S.
provisional patent application Ser. No. 60/335,908, which in its
entirety is incorporated by reference herein.
FIELD OF THE INVENTION
[0002] This invention relates generally to toys and games,
particularly to toys and games that identify objects.
BACKGROUND OF THE INVENTION
[0003] Toys are known which can respond to radio frequency (RF)
signals, e.g., toy vehicles having radio frequency transmitting
remote control units. Such toys typically respond to simple signals
such as "forward," "stop" and "reverse." They require batteries in
both the toy and transmitter.
[0004] RFID (radio frequency identification) transponder
technologies are known in the prior art and used in retail store
environments to sound an alert when products for which payment has
not been made are removed from the premises, and in other detection
systems such as automated toll-collection systems for highways,
bridges and tunnels,
[0005] e.g. "EZ Pass." While commercial RFID reader/interrogator
circuits have been available in industrial systems such as in
building access and security control systems, highway toll-taking
systems such as EZ-Pass, Fast Trak, and the likes, such circuits
can cost from fifty dollars to several hundreds of dollars and thus
are not suitable for use in a toy or game type product.
[0006] These commercial systems also involve a central or
stationary fixed location RFID reader/interrogator detecting and
recognizing items containing RFID tagged ICs, e.g. vehicles moving
through toll gates using EZ Passes, customers filling in their gas
tanks by waving RFID tagged cards, employees opening closed doors
by waving RFID tagged security cards, books being checked in and
out of libraries, etc. To obtain a large/long sensing and detection
area in these systems, the associated antenna or energy and
data-coupling element is generally larger than the RFID
reader/interrogator chip.
[0007] RFID electronic components, "reader/interrogator" and "tag"
circuits, are presently available in small, integrated circuit (IC)
packages from several semiconductor vendors such as Philips,
Motorola, Texas Instruments, Microchip, and Atmel, to name just a
few suppliers.
[0008] U.S. Pat. Nos. 6,361,396 and 6,364,735 disclose a method and
apparatus, which allow one toy to identify a plurality of objects
provided. The system relies on the inductive coupling of the toy
with a resonant frequency tank circuit contained within the object
to be identified. Physical contact between the toy and the object
is not required.
[0009] The inventions disclosed in these two patents, however, have
several limitations. One example is the total number of objects
that the master unit can recognize, as well as the total number of
objects that can be simultaneously recognized and distinguished, is
limited. Furthermore, when dealing with multiple objects, a number
of discrete frequencies in combinations have to be transmitted to
be able to determine the sum/differences in frequencies to identify
objects. Nor with the method of the above-mentioned patents can any
information or changing or variable information, such as
quantities, be written back to the object and stored for later
recall, revisions, or can additional information be written or
updated. This limits the play patterns and game play actions
possible.
[0010] The game industry is always looking for ways to enhance game
units and game/play patterns, while keeping the cost of production
down. The present invention fulfills this need.
SUMMARY OF THE DISCLOSURE
[0011] In accordance with the disclosure, contactless or remote
identification of objects by toy dolls and other toys can be
achieved through the use of RF (radio frequency) transponders,
commonly referred to and known to those skilled in the art as RFID
Tag integrated circuits, "tag ICs," or "tags." A master/host/server
toy or game unit (also herein referred to as "master unit") can
identify and recognize something that is placed within range of the
host without any physical or mechanical contact through the
application of RFID technology. Objects to be recognized and
identified by the master/host/server toy or game unit need only
contain a small RFID tag transponder integrated circuit chip (tag
IC) and a suitable RF antenna or energy and signal-information
coupling element. Such objects do not require a self-contained
battery or other power source to be recognized. No optical code
(e.g. bar code), invisible ink, ultraviolet or infrared ink is
required, nor is mechanical or physical contact necessary between
the recognizing toy and object to be recognized.
[0012] Tag ICs can respond differently from one another when
interrogated by an appropriately programmed master/host/server toy
or game unit. The tag ICs transmit and receive information in the
form of data bit streams to and from the master/host/server toy or
game unit. The tag ICs receive their operating power from the RF
energy transmitted by the master/host/server at the same time as
data exchange occurs. The tag ICs do not require their own separate
power source.
[0013] In addition to a toy or game master/host/server reading an
object's identity from its tag IC chip, tag IC chips can receive
information in the form of many digital bits written back and
stored indefinitely in non-volatile digital or analog memory
onboard the tag IC chip. This feature enables the creation of play
substance quantitative and nonquantitative attributes such as in
the form of kid's money, or a portable store of value, that can be
held, transferred, traded, or otherwise exchanged with compatible
devices, such as trading cards or "play money," which contain
read/writeable RFID tag ICs containing non-volatile, electrically
reprogrammable memory bits, utilizing appropriately programmed
master/host/server toy or game units containing an RFID
reader/interrogator circuit and suitable antenna. (The word "write"
is used herein to also include rewrite and update. This write,
rewrite, and update can be repeated a number of times as required
or designed by the game play or toy play-patterns.)
[0014] This feature, for example, also could be used with a doll to
simulate consumption and replenishment of a resource, such as
pretend milk in a toy milk bottle given to the doll. When a child
presents a "full" milk bottle with an RFID tag IC inside it
programmed as "full", then the doll can simulate drinking the milk,
and the master/host/server can gradually reprogram the RFID tag IC
in the milk bottle to be less and less full, as indicated by the
setting of some selected data bits in the milk bottle RFID tag IC
memory, via the rewriteable feature. When the milk bottle is
"empty" the doll could possibly cry and ask for more milk. Then the
toy milk bottle would have to be taken over to a different
master/host/server toy, perhaps in the form of a cow or a dairy, so
as to be "refilled" by way of having the selected data memory bits
of the milk bottle RFID tag IC be reprogrammed accordingly.
[0015] A trading card, a game-playing card, a teaching flash card
with visual information printed on it, a game-playing token, coin
or piece of currency, or other small object can be provided with an
embedded RFID tag chip and suitable antenna loop or coil, factory
programmed with specific bits of read-only data in the tag IC
memory. This card can be recognized by a talking doll, for example,
that can then recite information about the card. The information
can exceed that printed on the card and, for example, can contain
secret information about the card that can only be accessed by a
master/host/server toy or game unit. A doll can then recognize and
recite information about the trading card. In other words, at least
some of the recited information may be stored on the card. Possibly
most or even all of the recited information may be stored on the
card. This can greatly minimize the requirement on the doll memory
to store such recited information.
[0016] A tag IC with a suitable small antenna loop or coil can also
be placed inside a small plastic figure, such as an action figure
molded from plastic, that can be recognized by the doll or a reader
device.
[0017] Such master/host/server toy or game units can play games
such as spelling games, arithmetic games, shape and other
recognition games, board games, duels games, battle games, wagering
or betting games (e.g. betting on random or statistical behaviors
for fun), and other games. Master/host/server toy or game units can
be employed to recognize trading cards and other two and three
dimensioned collectibles. A master/host/server toy or game unit can
act on a tag IC in a collectible to change its data thereby
selectively making it compatible or incompatible with other
master/host/server toy or game units, thereby providing the ability
to "catch" or "collect" a specific object or flash or trading card
by a specific owner, after which it cannot be caught or collected
by another, unless the owner agrees to trade it electronically to
another owner, using the master/host/server toy or game
controller.
[0018] Objects to be recognized and master unit toys may be in any
two or three-dimensional form. Objects typically include things
such as flash cards containing letters, numbers, words, pictures,
animals, etc. Objects may also include miniature objects such as
toy baby bottles, food items, common household objects, discs,
tokens, pictures, coins, currencies, houses, etc. Action figures,
figurines, vehicles, animals may also be used as objects, as well
as master unit toys.
[0019] In another aspect of the invention, an RFID
reader/interrogator cartridge or accessory may be received, plugged
into, and/or connected and operated by game/computing devices such
as hand-held electronic game computing devices, PDAs (personal
digital assistant), hand-held computers, tablet computers, and the
like--for example, GAMEBOY and GAME BOY ADVANCE units from
NINTENDO.RTM., PALM.TM. hand-held computing devices from Palm,
Inc., or iPaq hand-held computing devices from HP. Alternatively,
the RFID reader/interrogator may be built-in into these
game/computing devices.
[0020] The RFID reader/interrogator accessory is generally plugged
into the game/computing device. The RFID reader accessory may also
have an interface to accept and connect game cartridges or game
packs, which contain ROM program(s) to operate the game or program
with the RFID reader/interrogator accessory.
[0021] Game-play operations of these game/computing devices, e.g.
video game or hand-held computing devices, generally involve
reading information from RFID tag chips that are embedded in
various objects or placed in objects at various locations. This
reading of information may also involve modifying variable play
substance values, such as adding power and points, or just
generally enhancing the game play. This game-play operations may
also be used for educational game purposes.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0050] In a first embodiment of the invention, RFID technology is
used to make a doll appear to "see" flash cards or other objects,
recognize them by name, and engage in play activity with them.
[0051] For example, in a "shape" game, the doll asks a child to
show or give the doll a specific shape, such as "the blue square"
or "the red triangle". The doll has a small loop antenna inside a
hollow cavity in the chest area, so that as flash cards or objects
are presented to the doll to "hold in its arms", a
master/host/server toy or game unit program can detect them and
respond with a voice in the appropriate manner. (Master/host/server
is herein also referred to as master unit.)
[0052] Furthermore, the sensing coil or coils, or sensing antenna
coupling elements of the master unit contained in the doll, can be
located in different places, such as the head, or in a hand or
foot, to localize the region where the target object will be
detected. (Note that the embodiments of the invention are not
limited to having coils as the only form of antenna or
energy/signal coupling elements. Antennas can include a number of
forms/elements, including, coils, loops of wire, or other
conducting materials, plates, areas, surface, or other forms. The
antenna and energy and signal information coupling elements may
also include capacitive coupling as well as inductive coupling
means.)
[0053] In addition, the doll could include not just one, but
multiple sensing antenna coils, located in various places on the
doll, and which are switched on and off by control of the host
microprocessor system. Such locations could include a coil in each
hand of the doll, a coil in each foot, a coil in the doll's head,
and a coil in the doll's abdominal cavity. Such a doll could play
games with multiple objects, but might also play games with a
single object by directing the user to sequentially position that
object at different antenna, and recognizing and reporting back to
the user as to the success or failure of each attempted
positioning.
[0054] In conjunction with the selectively switching of the active
antenna coil, the doll could ask the child to place a specific
object in the doll's right hand, or in its left hand, for example.
Utilizing a voice synthesizer, the doll can ask for specific shapes
to be given to it, and then for them to be taken away, one at a
time, with responses given as to whether each correct shape was
provided.
[0055] It is also possible that more than one or all antenna be
active simultaneously. This way a doll, for example, can ask for
specific shapes to be handed to it. The shapes may be placed, for
example, in either hands and still be recognized accordingly.
[0056] Objects presented to the doll can have numbers or spelling
words which can be enunciated by an electronic voice synthesizer in
the doll. The master unit can make animal sounds or other sound
effects corresponding to a picture card or sculpture of a presented
animal or other sound effect such as a fire engine or motor car.
The master/host/server or master unit may be provided with recorded
or synthesized music for playing different songs and tunes, perhaps
in different voices or with different sounding musical instrument
sounds such as a trumpet or a flute, a violin or a trombone, and
also with many different percussion sounds such as drums, bells,
whistles, and other sound effects.
[0057] The master/host/server or master unit may also provide user
presentations that are completely nonaudio. For example, visual
presentation on a display, tactile presentation (e.g. vibrating
master/host/server toy), and olfactory presentation may also be
presented. The master unit, however, has to include appropriate
components to handle such presentation. Audio and nonaudio
presentations may also be combined.
[0058] In accordance with the disclosure, a doll or other
master/host/server or master unit can remotely recognize and
identify an object, flash card, token, or other thing with no
physical or mechanical contact. The toy or doll or game can
recognize just one thing at a time, or a multiplicity of many
things at the same time (that is within a few hundred milliseconds
of one another) by utilizing the so-called "anti-collision" feature
of certain RFID tag ICs which are commercially available. Object
detection in general is handled by one or more programs operating
on microcontroller ICs in master units, in conjunction with RFID
reader/interrogators.
[0059] Referring to FIGS. 1A and 1B of the drawings, there are
shown a girl doll 110 and a baby doll 120, respectively, each of
which can contain an "engine" in the form of a master/host/server
toy or game unit 103. In addition to an integral antenna 105
located within the master/host/server toy or game unit (master
unit) 103 mounted in the doll's chest cavity, another antenna 105a
can be connected to the master unit 103 and mounted within the head
of the dolls 110 and 120.
[0060] The characteristics of the antenna, such as number,
placement, and shape, may vary depending on toy design. The dolls
110, 102, for example, may include additional antennas such as an
antenna in an external hair band around the head 105d, inside the
doll head and around the face area 105g, 105m, in either or both
frames of the eyeglass 105f, in a necklace 105h, in either or both
hands of the doll 105b, 1051, in either or both feet or shoes of
the doll 105c, 105j, in the holder 105i, in the tummy 105k,
etc.
[0061] Each of the dolls 110 and 120 is shown interacting with a
play object 108. The girl doll 110 is interacting with one in the
form of a card, while the boy doll 120 is interacting with one in
the form of an action figure. Play objects, as well as master unit
toys, may be in any two or three-dimensional form, such as bottles
106, trading cards, pictures, flowers, stuff dolls, lamps, grocery
items (e.g. fruits, milk cartons, vegetables, etc.), vehicles,
currencies, animals, etc.
[0062] The girl doll 110 may interact with a bottle play object 106
such that the bottle may be identified as full, half-full, or empty
in a game or play pattern. It may also identify cards, such as
identifying the shapes printed on the card. The boy doll 120 may
identify and interact with various action figures according to the
play pattern program controlling the microcontroller or
microprocessor.
[0063] Referring now to FIG. 2, there are shown a plurality of play
objects 108 that each include a nonself-powered RFID transponder
tag IC 108a and an RF antenna 108b. The play object may be, as
discussed above, in any form such as a flash card, a trading card,
or small object molded from a non-conducting, non-RF-shielded
material.
[0064] The RFID tag ICs 108a are nonself-powered, in the sense,
that they do not need their own power source, like a battery. They
obtain their power from the master unit via inductive or capacitive
coupling of sufficient energy using the antennas or energy coupling
elements. No physical contact is required to convey the operating
energy and power to the tag IC.
[0065] Radio signal communication of power and data to the play
objects may be accomplished by various means, including inductive
and/or capacitive coupling--primarily by magnetic and/or electric
field components of the electromagnetic radio signal.
[0066] FIG. 2 also shows a master/host/server toy or game unit 103
(master unit) having an RF transmitting and receiving antenna
sensing element or coil 105. This antenna may be of the primarily
inductive coupling or primarily capacitive coupling type.
[0067] The master antenna element or coil 105 is tuned to the
resonant operating frequency of the RFID tag ICs, and their
associated antennas. The master antenna element or coils 105 are
operatively connected to a reader/interrogator circuit 207.
[0068] The master/host/server or game unit 103 and the RFID tag
ICs, regardless of the number of RFID tag ICs, generally need to
only communicate with each other using one fixed frequency. Because
the RFID tag circuit operates at a single fixed frequency, the
resonant circuit can be tuned for optimum Q, the quality factor,
and thus perform with maximum energy coupling efficiency, which
also reduces the amount of power required from the batteries or
other power source to the master unit. The life of a battery or
batteries in battery-operated toys thus may be extended as a result
of the RF operation at one fixed frequency. Multiple frequency
operation to communicate with more than one RFID tag ICs is
unnecessary. Backup frequency, however, may also be implemented as
part of the toy design.
[0069] The frequency of the radio signal can be at various standard
frequencies used by the industry in standard components, including
the one hundred twenty five (125) kHz (nominal) band, the thirteen
(13) MHz (nominal) band, or other frequencies that may now be used
or in the future by RFID technologies, such as fifty MHz, one
hundred MHz, VHF, UHF, SHF, or SUFH frequency bands.
[0070] The circuit 207 transmits power to, and receives data
transmitted from, the RFID tag ICs 8a within its range. The circuit
207 may also transmit data to the tag ICs. The play object 108 may
typically be positioned about one to four inches from the master
antenna 105, or possibly further. In certain play patterns, the
detection range may be as minimal as one tenth of an inch to as
many as twelve to twenty-four inches or more.
[0071] When the reader circuit 207 transmits energy to a tag IC,
that tag IC uses the power to transmit its unique or identity data
back to the circuit 207. The master unit 103 then uses that unique
data to identify or "recognize" that object 108. That unique data
may be serial numbers. Thus, a card containing a picture of a horse
can be distinguished from one containing a picture of a pig.
[0072] In one embodiment, each play object in a product line of
toys is unique. This may be accomplished by having a unique piece
of information associated with each play object within that product
line. Serial numbers may be used. A smaller or larger collection of
unique play objects may also be defined.
[0073] Serial numbers may be assigned and written in the RFID tag
ICs during the manufacturing process. In one embodiment, a range of
serial numbers or a particular serial number is assigned to an
entity, such as apples. Thus, when a serial number within this
range or that particular serial number is read from an RFID tag IC,
the master unit accordingly and appropriately recognizes this
object as an apple.
[0074] In another embodiment, serial numbers are not used, but
rather a different identification information is used. In this
embodiment, a set of ASCII data is stored to identify that object.
For example, if the object is an apple, the ASCII equivalent of the
word "apple" is stored in the RFID tag IC. When that object is
detected, the identification information, in this case, "apple" is
read. The master unit accordingly recognizes this object as an
apple. This ASCII information may also be used by a text-to-speech
synthesizer to say the word "apple." Serial number and
identification information may both be used in an object.
[0075] It is also possible that data is not unique to a set of play
objects. For example, it is possible that in the play-pattern or
game, there are two red cards, and are accordingly identified as
such, for example, having the same serial number. Part of the game
play is determining whether the two play objects are the same or
different.
[0076] The uniqueness or degree of uniqueness of play objects in a
collection, whether in a product line, in a master unit/play
objects combination, in a toy package, and the like, depends on
product design, marketing, toy packaging, game play pattern,
etc.
[0077] The reader/interrogator circuit 207 is operatively connected
to a microcontroller/microcomputer 213. The microcomputer 213 has a
microprocessor. The microprocessor is connected to one or more ROMs
(read-only memories) 214 that contain program code (or control
program) for controlling the responses of the master/host/server or
master unit 103 to the data received from the tag ICs 108a. The
data from the tag IC "triggers" or causes the response of the host
unit 103.
[0078] The program code or control program is generally a set of
executable object code or machine instructions. It can be written
in a variety of source code programming languages and then compiled
and/or assembled into executable machine code or instructions
appropriate for the target microcontroller. For example, the
control program may be written in the C programming language and
compiled into runtime object code. The control program could also
be written in the native assembly language suitable for the
microcontroller and assembled into run-time machine executable
object code.
[0079] The control program operate all aspects of the input/output
control circuitry of the master/host/server or master unit,
including the control of the RFID transmitter and receiver master
circuit and the control of its read and write modulation of the RF
carrier signal used to interface to the RFID tag chip transponders
(play objects).
[0080] The microprocessor is also connected to RAM (random access
memory) for temporary storage of operating data. Provision for
connecting additional ROMS 215 to expand operating functions and
modes is provided in the form of external cartridge connectors 217
which allow additional ROMs 215 to be piggybacked onto or daisy
chained to the basic ROMs 214. The microcomputer 213 may have a
plurality of miscellaneous I/O lines to arm/hand switches and other
doll sensors.
[0081] The microcontroller includes various input and outputs
lines, which can control other portions of the electronic circuit
of the master unit, monitor pushbuttons or mechanical switch
contacts, send and/or receive serial data streams, control
available visual indicators, such as LEDs, and perform general
input/output control for the entire master unit.
[0082] A voice/sound synthesizer circuit 219 is connected to the
microcomputer 213 for converting digital data signals generated by
the microcomputer in response to or caused by the data received
from the interrogated tag ICs 108a to analog voice, music or other
sound signals. The sound circuit 219 may include CELP, ADPCM, or
the like.
[0083] As noted above, at least some, and possibly most or all, of
the data signals generated may be data returned from the memory of
the object 108. The analog sound signals are then applied to the
input terminals of an audio amplifier 221 for driving a speaker 223
which reproduces the sounds for listening at an audible level.
[0084] The microcomputer 213 and its associated components,
including the microprocessor, the voice/sound synthesizer circuit
219, and the amplifier 221 are powered by batteries contained in a
power supply 225. For example, four AA or C alkaline batteries may
be used. DC operating power can also be supplied from main AC line
voltage by way of a suitable step-down transformer, rectifier and
filter circuit as is commonly found in small, plug-in power
supplies, so as to save on use of batteries when in a fixed
location. DC operating power could also be supplied from twelve
(12) VDC found in motor vehicles such as cars, trucks, busses,
campers and even airplanes, by way of a suitable electrical
connector and cable connected to a DC voltage regulator in the doll
engine 103.
[0085] "Smart trading and game-playing cards" are another toy or
game application of RFID technology according to the invention.
Trading cards--e.g. baseball cards, football cards, and character
cards, game-playing cards--e.g. action cards, duel and battle game
cards, and role-playing cards, and other collectibles can each
contain an embedded RFID tag IC for enabling novel uses for trading
cards and collectibles in conjunction with dolls, and various other
master/host/server toy or game units. The master/server/host unit
can then detect each collectible as it is added to the collection
and maintain information about the inventory of collectibles.
[0086] Each collectible can have, stored in its tag IC, data which
associates the collectible with its owner. No other master unit toy
or game unit can recognize, transfer, or exchange the collectible
until its owner enables the stored data to be changed for
associating it with a new owner's master unit toy or game unit.
That is, once a specific figure or other collectible is "caught" or
"collected" once by someone, it cannot be caught or collected again
by someone else, unless it is "traded" by the original owner to a
new owner.
[0087] In still another embodiment of the invention, an RFID tag IC
can be used to store the "collection" and "ownership" values in the
memory of a tag IC embedded in an owner or collectors "master
card," and to allow for trading or exchange of value with another
owner/collector for creating "kid's money."
[0088] In many conventional trading card games, points are gained
and lost during the play of the game. With these smart trading
cards, points and values may be read and written during the course
or play of the game. Furthermore, because these smart trading cards
obtain its power from the master unit, a power source is not needed
to be directly attached to these smart cards.
[0089] Smart trading cards may be implemented using inductive
coupling with coils or using capacitive coupling with electrodes
formed from printing conductive inks on the surface of the cards.
Such conductive inks include black inks with "carbon black," i.e.
conductive carbon particles are blended with conventional or
water-based printing inks, and are printed with standard offset,
lithographic or other printing processes.
[0090] Conductive inks may be aluminum, silver, gold, or other
conductive materials printed on the back or inside surfaced of the
cards.
[0091] With such smart trading cards and other play objects
(described herein), the play substance values and information
stored in the RFID tag ICs may be read and updated (written) during
the course of the game. Such play values/information may include
virtual money, virtual weight of precious metal or a useful
commodity, or virtual volume of valuable liquid for barter or
negotiation in a game. It may also include virtual characteristic
or attribute values quantitatively measured. Such play substance
values/information may also be in nonquantitative form. For
example, such values may include "Y" and "N" for "yes" and "no,"
respectively. Other values include non-numeric values such as
"turtle," "cow," "house," "A," "B," symbolic symbols (for visual
displays), and the like.
[0092] Considering that play objects in general, and not master
units, contain values and information, a player can take a play
object to another master unit that has never previously been
specifically informed about earlier game transactions with that
play object, and still have the game ensue based upon earlier play
by that particular play object in earlier transaction with the
earlier master unit. The game ensues particularly based on
information/values stored in the play object by the earlier master
unit. All, majority, or portion of the prior ownership and/or
transaction value and history can be stored on the tag IC memory of
the play object.
[0093] The master unit can be another toy or game apparatus, for
example, in a public location such as a retail store or eating
establishment like a restaurant. The play object with the RFID tag
IC can be presented at the store to gain credits, obtain free
prizes, bonuses, or discounts on purchases, or other benefits.
Additional values or play substance values may also be added to a
play object at the store or point-of-purchase location.
[0094] For example, if a smart trading card containing virtual
money information is used in a casino game/play pattern, a child
may use this smart card, i.e. the virtual play money, and bring it
today to friend A to play with, and then take whatever virtual play
money the child has ended up with after playing with friend A to
friend B and C tomorrow. Thus the burden of keeping track of game
play transactions (including ownership transfer, hit points
changes, attributes changes, virtual money losses and increases,
etc.) is not placed on any particular master/host/server.
[0095] An example of a microcontroller 213 that may be used in an
embodiment of the invention is the RSC300/364 device from Sensory,
Inc. of Santa Clara, Calif. This component can be purchased from
the company at prices as low as $1.50 per device. This low price
qualifies the device as suitable for toy and game use.
[0096] The RSC300/364 is optimized for audio speech and sound
output, as well as for speech input. The CPU portion of the device
includes a suitable instruction set for controlling the RFID
transponder devices, as well as to initiate output of speech,
voice, sound or music signals from data tables stored in the fixed
data memory.
[0097] Similar microcontrollers, such as the W536 "ViewTalk" series
of microcontroller chips from Winbond Semiconductor Company Ltd.,
Taiwan, would also be suitable. These chips generally support sound
and speech audio output, and also include circuitry for operation
of a typical LCD display screen containing alphanumeric characters
and/or graphical, pictorial "icons".
[0098] Generally, the microcontroller 213 controls some external
circuitry which embodies the RFID radio frequency control and data
read/write transfers between the various RFID tagged objects and
the main host control.
[0099] A Hitag reader chip, HTRC110, from Philips Semiconductor
Corp. is an example of an RFID transponder reader/interrogator chip
207 used in a master unit 103.
[0100] This device comprises a complete one hundred twenty five
(125) kHz RFID transponder controller. It can be used with RFID
transponder tag ICs operating in the one hundred twenty five (125)
kHz frequency range.
[0101] In one embodiment, the HTRC110 is made to work with Philips
HiTag RFID tag devices, sold commercially by Philips Semiconductor.
These RFID tags are placed in play objects to be recognized by the
toy or game.
[0102] While the HTRC110 device is named a "reader" by the
manufacturer, it can also be used as a "writer" of data back into
non-volatile read/write memory contained in certain kinds of RFID
tag devices which support read/write memory operations.
[0103] Generally, very few external components are required to
operate the HTRC110 IC in accordance with the invention. For
example, only a few capacitors and a crystal for the precise
control of timing within the IC are needed. Furthermore, only three
digital I/O (input/output) lines are required to interface the
entire RFID Reader IC to the microcontroller: Data In, Data Out,
Serial Clock. This is well known and widely used in the industry,
and is sometimes known as an I2C link.
[0104] The control program in the microcontroller transmits control
and data information to the reader/interrogator IC, and reads back
control and data information from it via the above-mentioned three
serial data lines.
[0105] Any and all control and data exchange functions of the RFID
reader/interrogator chip may be implemented via the above-mentioned
three lines: transmit RFID carrier On/Off, read data, write data,
modulation control or the RFID carrier, demodulation control of
received data, and error detection and correction.
[0106] As mentioned above, data/play values may also be updated or
written back to the memory of the RFID tag ICs. These data may
represent increased points in a game, ownership identification of a
plastic toy figurine, or other toy and game-related
information.
[0107] Another example of an RFID reader/interrogator is the
standalone tag reader circuit (STARC), MC33690, from Motorola.
RSC-300/364 chips from Sensory, Inc. in Sunnyvale, Calif. may be
used as voice/sound generator chips.
[0108] Philips HiTag RFID tag devices may be used in play objects.
These RFID tags include the feature of reading and writing back
data into a non-volatile memory on the tag IC device.
[0109] HiTag devices also support the so-called "anti-collision"
feature that enables more than one RFID tag device to be recognized
and controlled within the range of the play field antenna. They
operate in the one hundred twenty five (125) kHz frequency band.
This type of device generally uses amplitude modulation (AM) for
the write-to-tag-memory process, and AM/PM for the read
control.
[0110] The anti-collision feature functions in such a way that
there is a random delay or a programmed delay in which a specific
RFID tag IC remains "off," i.e. does not respond with a
transmission back to the RFID reader/interrogator. This way
multiple RFID tag ICs (play objects) may be polled sequentially.
This gives rise to the appearance of simultaneous responses because
the time required for an interrogation/response is quite
brief--tens or hundreds of milliseconds.
[0111] MCRF200, a contacless programmable passive RFID device, from
Microchip Technology, Inc. may be used as an RFID tag IC. This
chip, however, only allows for read-only data transmission. It also
does not support anti-collision, thus it is suitable for "one at a
time" play-object recognition game pattern.
[0112] If anti-collision features are desired, MCRF250 and
MCRF355/360 from Microchip Technology, Inc. may be used in play
objects. These chips may be used when multiple objects are to be
detected at apparently the same time in a game environment.
[0113] MCRF200 and MCRF250 devices operate in the one hundred
twenty-five kHz frequency band. They are read-only and are one-time
programmable with a unique serial number. Hence, they can be used
to represent many different tagged play objects. Up to ninety-six
bits of serial number can be programmed, supporting trillions of
unique identification codes.
[0114] Other RFID tags, using other types of signal modulation
(e.g. AM, AM/PM, FSK, Direct PSK (change on data change), PSK
(change at the beginning of a one)) and data encoding methods (NRZ
Direct, Differential Bi-Phase, Manchester Bi-Phase, Bi-Phase IDI)
suitable for required error detection and correction capability may
also be used.
[0115] Other frequency bands may also be used. RFID tag devices
such as the iCode from Philips Semiconductor and the MCRF 355/360
and MCRF450 from Microchip Technology Inc are but two examples of
devices operating in the 13.56 MHz radio frequency. Other RFID tag
systems operate at SUHF frequencies in the five GHz range, such as
devices manufactured by Hitachi.
[0116] If read and write features are desired, i.e. be able to
write and update information in the play object, MCRF450 from the
same company may be used.
[0117] While some RFID systems operate using primarily inductive
coupling of the power and signal energy from the master unit
reader/interrogator to the RFID tag IC, other RFID technologies use
primarily capacitive coupling. For example, the BiStatix RFID
devices from Motorola use capacitive coupling.
[0118] In embodiments of our invention, either inductive or
capacitive coupling can be used--depending on the toy or game and
the nature of the play objects being recognized. For example, a
capacitive coupling element (antenna) can be formed by printing two
surfaces with electrically conducting ink or other substance onto
paper, plastic, cardboard, or other non-conducting material. These
two surfaces form the two plates of a capacitor, which performs the
signal and power energy coupling between the host and the RFID tag
object. This method can be used to "print" smart trading cards,
playing cards, collecting cards, or other flat, generally
two-dimensional type objects.
[0119] Other chips or devices that support the functionalities and
features described herein may be used in making the
master/host/server and the play objects. Furthermore, there are
many possible configurations of electronic circuits for RFID
reader/interrogator devices and play objects. For the purposes of
electronic toy and game playing systems, the cost of the electronic
components generally must be very low, typically costing under five
dollars.
[0120] User presentation, such as visual or audio outputs, may also
be implemented by coupling such reader/interrogator circuits with
appropriate display and/or audio circuits. Master/host/server or
master units, for example, may include various visual display
mechanisms, such as colored light indicators (typically LED
devices), and alphanumeric display screens such as formed by LCDs
(liquid crystal display), LEDs (light emitting diodes), and in dot
matrix or custom graphic "icon" formats. Such displays convey text
and numerical information including words, statements, or other
visual information. User-presentation depends on the instructions
contained in the program controlling the microprocessor.
[0121] In the case that the master/host/server or master unit has
multiple antennas, switching circuits are used to enable or disable
individual antenna elements. This is done under the control of the
control program. The control program can also sequence the various
antennas to determine if play objects are/are not placed in certain
locations, and respond accordingly. This is generally dependent on
the play-pattern or game environment enforced.
[0122] The exchange of power and data signals between the
reader/interrogator and the play objects occurs rapidly, typically
within one hundred through three hundred milliseconds for one
hundred twenty kHz carrier frequencies of operation, and within
under one hundred milliseconds for thirteen MHz carrier
frequencies, if not faster. RFID tag systems operating at thirteen
MHz or five GHz have much faster response and data exchange timings
because of the higher carrier frequencies.
[0123] Thus, the response time of a master unit to play objects may
appear to be almost instantaneous as far as human perceptual speeds
are concerned. This also means that multiple antennas and coupling
devices can be switched and multiplexed quickly such that the
response of the master unit appears to be instantaneous by human
perceptual speeds.
[0124] Referring to FIG. 3, antennas, particularly for the master
unit, are preferably oriented orthogonally with each other and
multiplexed or fed with complimentary RF signals. This enables
detection of play objects in case the coupling antennas are at
obtuse angles and enables the RFID reader/interrogator to read and
interrogate a passive RFID tag with coil in any angular position
within the sensing field.
[0125] With a single loop antenna, the RFID tag IC and its antenna
must be closely coupled to the signal field so that sufficient RF
energy is coupled to power and communicate with the RFID tag
device. For toys and games, however, there may be situations in
which a single loop antenna is not able to recognize a small RFID
tag device, that is, if the RFID tag device is orthogonal to the
master unit loop antenna, energy coupling would be minimized and
the tag IC would not be recognized.
[0126] Thus, a second loop antenna oriented at ninety degrees to
another antenna is preferable. The multiplexing method of
selectively enabling and disabling multiple antennas (discussed
further below) may then be used so as to ensure maximum signal
coupling to the RFID tag at any angle within the sensing field. A
third or more antenna can be added to the setup in a similar
manner, at other angles to the detection area or space, so as to
maximize the RF coupling efficiency to the tag IC without regard to
a specific orientation of the play object in three-dimensional
space.
[0127] In one embodiment, a master unit reader antenna is a coil of
wire or a conductive printed loop of thin copper. The antenna is
preferably tuned to the reader/interrogator circuit by a series or
parallel capacitors.
[0128] The size and dimensions of the antenna and its electrical Q
factor determine how sensitive the reader/interrogator antenna is
to weak RFID-tagged play objects and how efficient such antenna is
in converting electrical power into the RF energy to implement or
trigger the play object-detection. The design of antennas in the
master unit, as well as in the play objects, thus are considered.
In one embodiment of the invention, an antenna is formed by making
a six-inch diameter loop consisting of twenty turns of #32 enamel
insulated copper having a low-series resistance. This antenna is
then placed over the head of a toy doll, for example, enclosed
within a plastic sheath so that it appears to be a hair band or
head band fashion accessory.
[0129] Loop antennas could also be placed within and disguised in
such things as necklaces, lockets, bracelets, belts, sashes, or
other parts of a doll or the master unit itself. This loop antenna
can also be placed inside the plastic head of a doll. Diameters of
antenna loops may also be varied depending on where in the master
unit, e.g. head versus hand, the antennas are going to be
placed.
[0130] The term "antenna" includes specific RF energy and signal
coupling devices and elements, such as small or large coils or
loops of wires or RF conducting materials in the case of
inductively-coupled signals, surface electrodes in the case of
capacitively coupled signals, or other combinations thereof. The
size and value of the antenna may be as large or small as practical
or as required by the play pattern or game.
[0131] Even if multiple antennas are used, only one master
reader/interrogator controller may be required (FIG. 4). For
example, if four antennas are used 410, 412, 414, 416, they only
need to be coupled to one reader/interrogator such as the HTRC110
HiTag reader 408 from Philips.
[0132] This exemplary circuit uses four antennas and eight MOSFET
transistors to selectively enable and disable each antenna by way
of four digital control signals D1, D2, D3, and D4 418, 420, 422,
and 424. The group of eight transistors forms a DP4T (double pole,
four throw) electronic switch with very low "ON" impedance and very
high "OFF" impedance. The four digital drive lines 418, 420, 422,
and 424 originate in the control of the microcontroller and are
buffered by logic inverters to switch the MOS transistors, which
are biased by VDD at five VDC and Vss at ground level.
[0133] Furthermore, each of the four output pairs to each antenna
may contain an additional fine tuning capacitor (C1 through C4)
426, 428, 430, 432 so as to provide the highest Q of the circuit
for maximum energy transfer. In this exemplary circuit, one and
only one antenna is enabled to be active at any given time. This
circuit, however, may also be use to activate one or more antennas
simultaneously with each other.
[0134] The TX1 434 and TX2 436 signals from the HTRC110 RFID reader
IC 408 feed into and are received from the common two signal lines
normally used for a single antenna.
[0135] Referring now to FIG. 5, HTRC110 RFID HiTag
reader/interrogator IC is used as an exemplary IC1 560. An
RSC300/364 chip IC2 562 is used as a voice/sound generator and
synthesizer.
[0136] The RFID reader IC 560 includes a four MHz quartz crystal or
a ceramic resonator (XTAL 1) 574 for timing of the RFID chip 560.
The main antenna L1 in the form of an inductive loop provides
energy and signal communications with RFID tag devices (play
objects) within its field of operation or detection area.
[0137] A tuning capacitor for output signal is also part of the
chip 560 to adjust resonant frequency of output for optimum Q.
Furthermore, couples receive energy signal back from RFID tag
modulation into the RECEIVE signal processing circuits of the RFID
reader chip 562.
[0138] The RSC-300/364 IC 562 is an eight-bit RISC microprocessor
with digital input and output, audio signal output from internal
sound synthesizer, data memory, and program memory. This IC 562 is
powered 564, for example, by four AA Alkaline batteries or other
source of four to six VDC power.
[0139] An ON/OFF switch SW1 566 to turn the IC ON or OFF is also
available. A speaker SPKR 568 is used to output audio information
(e.g. voice, music, and sound effects). This chip 562 contains an
audio output amplifier to drive the speaker 568, in this case, a
two-inch diameter sixteen to thirty-two ohm impedance speaker.
[0140] An audio output filter capacitor COUT 570 is also included
for better quality. A fourteen MHz crystal (XTAL 2) 572, which may
also be used by the main clock of the CPU, is also available. Port
zero lines PO1, PO2, PO3 578 are included for digital input/output
control of the RFID reader by the CPU. A reset-circuit 580 is also
available to provide proper reset of CPU at power on.
[0141] Similar to the master/host/server 103 described above (FIG.
2), a master/host/server in another embodiment (FIG. 6) includes a
visual display generator/controller 602 that controls a visual
display. This way a toy may be responding not in audio form but in
visual form.
[0142] The visual display 604 is generally used for user
presentation and may include LEDs, OLEDs (organic light-emitting
diode), LCDs, CRTs, incandescent lamps, 3D holographic or 3D
stereographic displays, and other types of display
technologies.
[0143] The visual display elements 604 may be single lights in
various colors or white lite, alphanumeric LED or LCD displays, and
fully dot matrix and raster type displays in monochrome or color
screens, capable of showing numeric and alphabetic characters in
many different fonts and languages, and full pictures and motion
video and animation type images. Using 3D displays also supports
fully synthetic images, such as holograms or stereographic
displays. Motion color videos and film images of photographs,
action scenes or any other types of visual displays such as are
seen on TV and movie screens may also be supported.
[0144] Visual display-driver integrated circuits 602 are
commercially available from many companies, including Sun Plus,
Microchip, Toshiba, National Semiconductor Corp, Texas Instruments,
and many others.
[0145] For example, the SPLD801B LCD segments driver and companion
SPLD802A LCD commons driver from Sun Plus may be used. Each of
these IC can drive eighty segments or eighty columns for
multiplexed LCD displays forming dot matrix images in arrays of
eighty by eighty, or more pixels. These displays can form numbers,
letters, icon graphic images, and other visual information. This
type of LCD display driver typically interfaces to a controlling
microcontroller unit via a few serial data, clock, and control
lines.
[0146] Other LED displays can be driven with just bit output lines
from the microcontroller driving an LED indicator light, or via a
2N2222 type transistor to boost the current. Incandescent lamps may
also be driven this way.
[0147] In one embodiment, with just eight output pins from the
microcontroller to drive LED anodes and another eight pins to drive
LED cathodes via 2N2222 transistors to boost current, an eight by
eight (8.times.8) matrix of LED lamps can be driven in scanned
multiplex mode to display alphanumeric characters.
[0148] In another embodiment, Motorola MC144898 five channel
LED/twenty five lamp driver can be used alone or in groups to drive
a number of LED lamps in single or dot matrix, alphanumeric
configurations. Using IC devices for CRT controllers or LCD display
controllers, full large screen video or LCD displays in monochrome
or color can be operated.
[0149] A number of IC devices manufactured and marketed by Epson
Semiconductors can support CRT or LCD displays, or both, in
embedded systems. Some examples are SPC8106 VGA LCD/CRT Controller,
SED1330 LCD Controller, SED1353 LCD Controller, SED1354 LCD/CRT
Controller, SED1355 LCD/CRT Controller, SED1356 LCD/CRT/TV
Controller, SED1374 Embedded Memory LCD Controller, and SED1375
Embedded Memory LCD Controller.
[0150] In another embodiment, a microcontroller can control both a
visual display generator/controller and a voice and sound
generator. This way a toy may be designed to have both visual and
audio user presentation.
[0151] Referring now to FIGS. 7A and 7B, in still another
embodiment of the invention, RFID tag ICs 708a and suitable antenna
708b can be embedded inside of play objects 708 in the form of
small play blocks molded from plastic, carved from wood, or other
non-conducting, non-RF shielding materials. The master unit and
control engine 703 is contained inside of a large tablet-shaped
form 701. The engine 703 includes the sensing antenna coil 705 in
the surface 709, a reader/interrogator circuit 707, a
microcontroller 713 with voice/sound generator IC, an audio
amplifier and speaker 721/723, and batteries 725, similar to the
arrangement shown in FIG. 2.
[0152] The "magic tablet" 701 can recognize the play blocks 708
placed on it. The play blocks 708 may have printed or molded
legends 708d on one side of the cube, such as letters of the
alphabet, numbers, arithmetic signs such as +, -, / and X, or
pictures or icons of animals such as cows, horses, chickens, or
pigs, or other objects such as musical instruments, musical notes,
or other things.
[0153] The magic tablet 701 has a similar "engine" 103 as the dolls
described above. The control program could operate in many
different modes.
[0154] In speaking only, the tablet voice just says the name of a
letter or number block placed on it. If a number of blocks are
placed on the tablet, using anti-collision techniques, the master
unit 703 accordingly identifies and processes all the blocks
placed.
[0155] The magic play blocks 708 and tablet 701 may have
complementary Velcro, or possibly magnetic, surfaces 710a, 710b for
establishing a preferred orientation of each block and its antenna
708b to the tablet and its antenna 705 so as to maximize the RF
energy transferred between the master unit and the RFID tag IC 708a
and antenna 708b contained inside the block or object 708 placed on
the magic tablet.
[0156] Alternatively, referring to FIG. 7C, the play block or
object 758 could contain the RFID tag IC 758a and small loop
antenna coil 758b in a diagonal orientation inside the play block
or object, so that regardless of the play block or object
orientation to the tablet surface 709, the loop coil antenna 758b
inside the play block or object will couple sufficient RF energy to
the associated RFID tag IC 758a in that play block for proper
operation with minimal transmitted power.
[0157] The tablet 701 can also ask a child to spell a word such as
"DOG" and then detect when the correct letter play blocks 708 have
been placed on the tablet, and speak accordingly, correct or not,
to help teach a child how to spell. In this embodiment, the
locations or positions of where the blocks are placed are not
considered.
[0158] In one embodiment, the word "DOG" is spelled correctly when
a child places the correct letter one after another, i.e. "D" then
"O," and then "G." How the blocks are placed on the tablet does not
affect how the RFID reader/interrogator reads the data contained in
the RFID tag IC, so long as the play letter object is in the
detection area of the RFID reader/interrogator.
[0159] In another embodiment, a child may place all three play
blocks ("D," "O," and "G") at the same time to correctly spell the
word "DOG." Still in another embodiment, the order of when the
letter blocks are placed is irrelevant so long as the correct
letter blocks are placed.
[0160] Detection of multiple play blocks or objects 708 is again
accomplished by the control program of the microcontroller 113 and
the reader/interrogator circuit 707. Data that are exchanged, that
is transmitted by the RFID tag and read by the reader/interrogator,
are actual digital bits of data and not just resonance
frequencies.
[0161] The circuit of the reader/interrogator 707 operates at the
selected RF frequency of the RFID tag IC 708a and antenna 708b.
Commonly used frequency ranges are 100-150 kHz, or 13.5 MHz
nominally, or other frequencies.
[0162] The specific methods of data modulation used in a specific
RFID tag system are not of consequence to the inventions of toys
and games. The basic operation of the invention can be adapted to
various modulation methods and frequency ranges, depending on the
cost of the circuits and the range of operation.
[0163] It is very important to note that the detailed control of
the reader/interrogator circuit and the data transmission and
reception is highly dependent on the control of the
reader/interrogator circuit which is effected by portions of the
operating system and drivers contained in the main "engine."
[0164] The disclosed master/host/server toys or game units can deal
with detecting multiple play objects i.e., where more than one play
object are presented to or removed from the toy or game master.
[0165] For example, a doll 110 can ask to "see" three shapes in
flash cards or play objects 108 containing suitable RFID tag ICs
108a. Then the doll can ask for one of the shapes or objects 108 to
be removed. If the incorrect one is removed, the doll will
recognize that, and speak a suitable warning response.
[0166] Because a considerable amount of power is consumed with the
activation of the reader/interrogator circuit 107 to transmit RF
energy to detect the possible presence of an RFID tag IC 108a
within the range of the master/host/server toy or game unit, such
operation must be managed carefully. The master control program can
manage the activation of the reader/interrogator circuit 107 on a
time-multiplexed basis, so as to conserve power in operation and
therefore prolong the battery life of the toy or game.
[0167] For example, the discussed apparatus provide for the
time-multiplexed activation of the reader/interrogator circuit 107
on a time interval basis to conserve battery power. Rather than
leave the reader/interrogator circuit 107 activated on a continuous
basis, the master/host/server or master unit 103 only activates
this circuit 107 very briefly a few times per second, until a
suitable RFID tag IC 108a is found to respond. In this manner, the
method of control reduces the power consumption by a significant
amount, and extends the battery life of the toy or game unit.
[0168] Referring now to FIGS. 8A and 8B, there is shown a smart
trading card master device 803 in the form of a hand-held reader
for smart trading cards or flash cards 808. A trading card 808 can
be slid into a mechanical slot 812 provided for the purpose of
holding the card 808 in place, the card can be placed on the
surface of a hand-held reader, the card can be waved in front of a
table (e.g. FIG. 7 or 13), or via other means for read/write
detection and operation by the master unit.
[0169] The reader 803 has a reader/interrogator circuit 807 and
antenna 805 for communicating with the RFID tag ICs 808a embedded
within the trading or flash cards 808. The trading card control
master (master unit) 803 can read and write back selected data
information to and from the RFID tag IC 808a embedded in the
trading card 808. This is performed under the control of a single
chip microcontroller 813 which includes a speech/sound synthesizer
circuit 819 with digital to analog converter suitable to drive
audible sounds from a miniature loud speaker 823 inside the
unit.
[0170] Moreover, the microcontroller 813 can include the circuitry
to drive segments and layers of a common, multiplexed LCD
alphanumeric display screen 814 on the master unit, whereby
information can be visually displayed. Power to the master device
803 may be provided by batteries 825.
[0171] In addition, the microcontroller can include circuitry to
communicate with an external device such as a personal computer, a
hand-held computer, or other device, via a wired serial
communications interface for RS-232, USB, IEEE 1394 or other
standard or custom communications network.
[0172] With such a network communications link, information about
the trading cards, their values, ownership, or other information
can be communicated to other programs and services, and could also
be conveyed via the Internet to various websites offering prizes,
recognition, or other services to the card collector or game or toy
player.
[0173] In a text-to-speech application of the invention, words and
phrases can be encoded in the tag IC memory in the form of ASCII or
other generally known and used character encoding techniques by
using RFID tag ICS with a sufficient number of data bits or read
only or read/write memory.
[0174] For example, the word "HOUSE" can be encoded in 6-bit ASCII
code, that is six data bits per alphanumeric character, using a
total of only thirty data bits. The RFID tag IC containing this
data bit pattern could be embedded inside a flash card, a trading
card, or any other small two or three-dimensional object.
[0175] Upon detection and query of the flash card, trading card, or
other object by the doll, a reader or other master unit toy or game
unit, programmed to recognize the encoding of words, the five
letters of the example word "HOUSE" would be received and then
conveyed to a software program and/or combination of software
program and voice, sound or speech synthesizer, in any of many
various languages, to be converted into the spoken word "HOUSE" by
the toy or game unit.
[0176] A very important feature of this embodiment of the invention
is the ability to form hundreds, thousands, or even millions of
unique identity flash cards, trading cards, or other play and
collectible objects containing RFID tag ICs, which then cause the
master unit toy or game unit to speak, or to display and speak, the
word or words programmed within them. This is significantly
different from using a master unit toy or game unit that has a
sound and speech voice synthesizer using only pre-recorded words or
phrases of language, which would be activated by control and
behavior programs in the toy or game unit.
[0177] In the foregoing embodiment of the invention, there can be a
virtually unlimited range or spoken words and phrases, activated by
one or more suitably programmed RFID tag ICs contained in flash
cards, trading cards, or other objects. As noted above, if desired,
the major portion, if not all, of the spoken or displayed data may
come from the object's memory. The main advantage of this
implementation is that the toy or game unit does not have to be
completely pre-programmed with all the words it might ever have to
speak or say or display. Rather, the toy or game unit need only
have a text-to-speech converter program in its control program,
with proficiency in one or more spoken languages. Such a toy or
game unit could be of use in learning and teaching various
languages.
[0178] The number of data bits in the RFID tag IC, perhaps as many
as one thousand bits, could contain as many as 150 alphanumeric
characters, (i.e. letters, numbers, punctuations, and other control
codes) sufficient so that one flash card, trading card, or RFID tag
IC equipped object, could cause the doll, master unit toy or game
unit to speak a specific sentence or sentences of multiple words
and phrases.
[0179] In another preferred embodiment of the invention (FIG. 9A),
a hand-held game device 920 receives an RFID reader cartridge 904
and a game cartridge 902. The hand-held device 920 typically
includes a microcontroller, a visual display 924, e.g. an LCD or
LED, sound-generation circuits, an audio output speaker 926, and
control buttons 922.
[0180] The RFID reader cartridge 904 is preferably a plug-in
accessory that fits into hand-held video game devices such as
NINTENDO.RTM. GAME BOY, NINTENDO.RTM. GAME BOY ADVANCE, and other
types of programmable hand-held game and computing units. This
plug-in accessory may also be designed to fit into hand-held
computing devices like PALM computers, PDAs, and even with console
video games units like SONY PS-2, NINTENDO GAMECUBE, MICROSOFT
XBOX, etc.
[0181] The RFID reader cartridge 904 includes RFID
reader/interrogator circuit(s) 908, antenna(s) 906, and
control/interface circuit(s) 910 to the hand-held device 920,
particularly to the main bus. The antenna sensing elements 906
preferably protrude out or are placed on the rear side of the RFID
cartridge 904, and preferably formed as loops.
[0182] The RFID cartridge 904 is generally plugged into an
interface or slot 928 available in the hand-held device 920. This
interface 928 is generally where game cartridges are plugged in or
inserted. For NINTENDO.RTM. GAME BOY ADVANCE, for example, the game
cartridge or game pack is plugged or inserted at the back of the
unit. This interface or slot 928 includes multiple electrical
connections to supply operating power to the game cartridge 902 and
the RFID reader cartridge 904 and for connecting address, data, and
control signal lines or generally to the main bus.
[0183] The RFID reader circuit 908, with the antenna 906, reads and
writes information back to play objects 990. This play object 990
has at least one RFID tag circuit 994 and an associated antenna
992. The play objects may be in many forms, including action
figures, cards, and the like.
[0184] The RFID reader cartridge 904 is preferably an intermediate
cartridge which plugs into the hand-held device 920 via the
interface/connector/slot 928 (FIG. 9B)
[0185] The RFID cartridge 904 also includes a receiving
interface/connector/slot 912 into which a game cartridge 902 may be
plugged-in.
[0186] This connector/interface 912 is generally a pass-through
interface so that the game cartridge 902 is able to convey all
program code and data to the hand-held device 920. The control
circuits 910 is generally used to interface input/output controls
to the hand-held device 920.
[0187] The game cartridge 902 contains the play-patterns or "the
game" that is going to be played by a user. It typically includes a
memory chip, such as a read-only-memory (ROM). The ROM contains the
operating program and data patterns for graphics, sounds,
animations, and game play.
[0188] The RFID cartridge 904 also includes interface circuit(s)
910 to the main bus of the hand-held device 920. Instructions on
how to process the information read by the RFID reader circuit 908
are also contained in the game cartridge 902. Such RFID
instructions control how information read by the RFID reader 908 is
processed within the game.
[0189] In this embodiment, a multitude of games or play-patterns
may thus be designed to work with various play objects. Playing
video games on hand-held devices is thus enhanced with the
introduction of RFID reader cartridges and RFID play objects.
[0190] These RFID play objects may contain serial numbers, identity
numbers, or other types of information such as those related to the
object or to the game in general. This information may thus affect
how a game is played.
[0191] For example, as a user holds an RFID action figure play
object 990 and passes it over or near an antenna 906 (i.e. the
figure is in a detection area), the RFID reader 908 reads the
contents of the RFID tag ICs 994. This information may then enable
this character in the game (i.e. bring this character into the
game), alter attribute values, such as strength and hit points,
instruct the hand-held device 920 to say "Hey, it's Superman!,"
alter the logic of the play-pattern of the game, give clues to the
users, extend playing time, and the like.
[0192] The RFID reader cartridge 904 may obtain its power from the
hand-held device 920. It is also possible that the RFID cartridge
904 has its own source of power, such a battery that is part of the
RFID cartridge 904.
[0193] In another embodiment of the invention, the hand-held game
or computing device has an integrated or built-in RFID
reader/interrogator under the control of a microcontroller or a
processor. Thus, the RFID cartridge 904 is thus unnecessary. A game
cartridge with the desired play pattern or game needs to only be
inserted into these hand-held game devices. The program contained
in this game cartridge dictates how the processor controls the RFID
reader/interrogator circuit. The antenna associated with the RFID
reader/interrogator may be placed in various location of this
device, such as front or back of the unit.
[0194] In another embodiment of the invention, instead of a
handheld game device, a video game console unit 930, such as an
Xbox unit of Microsoft Corporation or a PlayStation.RTM. unit of
Sony, is connected to a television console 932. The video game unit
930 is connected to the tv via a wire interface 934.
[0195] The video game unit 930 has a built-in or integrated RFID
reader/interrogator 940 and an associated antenna 948. It also
includes a processor 942. The game or play pattern that is going to
be played is contained typically in a readable medium 936, such as
a CD-ROM. It contains the program of the game.
[0196] The software or program 936 is loaded into a
program-receiving unit 938, such as a CD reader. In conjunction
with the processor 940, the instructions contained in the program
are executed by the processor or by appropriate components
typically under the control of the processor. The RFID
reader/interrogator circuit may also be under the control of the
processor.
[0197] The program or software 936 may also be received by the
video game unit 930 via a connection, such as the Internet.
[0198] RFID tagged play objects may be waved or placed near the
game 930 and accordingly recognized and processed under the rules
of the game. User presentation such as visual display and audio
output are presented by the connected television or display unit
932.
[0199] Alternatively, the RFID reader/interrogator 940 and
associated antenna 948 is not integrated with the game device 930.
In this scenario, an RFID reader cartridge is plugged into an
available port in the game device 930. The program 936 loaded into
this game device and the processor controls the RFID
reader/interrogator including how data read should be handled.
[0200] In another embodiment, a hand-held game or computing device
950, such as an iPaq unit from HP or a PDA, includes a visual
display 954. It also includes an RFID reader/interrogator 960, an
antenna 952, a processor 962, a speech/sound synthesizer 964, and a
speaker 966. The game program may be preloaded into this hand-held
unit or be downloaded into this unit via other means, such as a
connection to the Internet or a connection to a software/program
media reader. User presentations are all handled by this same unit
950.
[0201] Alternatively, the RFID reader/interrogator is not
integrated to the system but is available as a plug-in accessory.
As devices become popular, they, however, become integrated into
the system, like Ethernet cards are now becoming standard devices
built-in into computer laptops and notebooks.
[0202] Thus, in general, in this type of game/computing devices,
the RFID reader/interrogator may be built-in or integrated in the
game/computing device, or may be available as an accessory to be
plugged in or connected to the main game/computing device. User
presentation may be presented by the game/computing device itself
and/or by external devices connected to such game/computing
device.
[0203] Referring to FIG. 10A, in one embodiment, these play objects
containing RFID tag ICs are manufactured containing initial
ownership status information 1004. This initial status information
may be in several forms, e.g. a bit "0" indicating that this object
has never been owned, a series of blanks or nulls indicating no
ownership, or a textual field with "never been owned" written on
it.
[0204] Initial value information, for example, play currency, hit
points, strength level, character level, name, etc. may also be
stored as part of the play object 1004. This value or set of
values, including status information, may be numeric and/or
non-numeric.
[0205] Once a play object is purchased for the first time, the
store using a master/host/server (transactor 1033 FIG. 10B), i.e.
capable of handling transactions, including writing to play
objects, updates the play object with new ownership information.
This master unit or transactor 1033 is coupled to an input device
1044 enabling the purchaser of that play object to enter ownership
information, such as name, address, and phone number. This input
device 1044 may be a keyboard, a touch screen, a computer, a
voice-activated input device, or any input-enabling device. Other
master units able to handle this type of transaction may also be
used.
[0206] Once the purchaser provides his or her ownership
information, the master unit transmits and writes this information
into the RFID tag ICs of the purchased play object 1006 (FIG. 10A).
Security information 1008, such as password, is generally also
entered by the user so that future ownership information may only
be written into that play object if a proper password is provided.
This password is also stored in the play object.
[0207] Other values of the play object may also be updated
according to the play-patterns programmed in the master unit
1010.
[0208] In the future, if the owner decides to trade or sell this
particular play object to another person, the owner may do so by
using a master unit. The owner may use any master unit that is
capable of handling this type of play-pattern transaction.
[0209] To enable the transfer transaction, the current owner enters
the same password previously stored in the toy. This security
information is verified by the master unit 1012. This is done
assuming that the play object is within the area of detection, i.e.
the RFID reader/interrogator communicates with the RFID tag ICs of
the play object.
[0210] In more detail, the RFID reader/interrogator of the master
unit reads the RFID tag ICs of the play object--particularly the
password. The password entered is then verified against the
information read. This is done by the microcontroller, under the
control of a program.
[0211] If the password entered matches the one stored, the master
unit enables the new owner to provide new ownership information and
security information via an input device. This new ownership
information and security information are stored in the RFID tag IC
of the traded play object, for example, card 1014, 1016.
[0212] Password security thus ensures that only valid transactions
are written into the play objects. Theft and illegal possession of
play objects are thus alleviated.
[0213] This process may be repeated if the play object is later on
transferred to another owner. Ownership information history may
also be stored thus enabling users to see its history. Other types
of information may also be stored in play objects, including
numeric values (e.g. monetary values), alphabetic values, and
nonalphabetic values. With the transfer, values of the play object
may also be updated according to the rules or logic of handling
such transactions 1018.
[0214] Non-face-to-face exchanges and trades may also be done. The
current owner may send the play object and the valid password to
the new owner. The new owner may then use an available and
appropriate master unit to store new ownership information. The new
owner does this by supplying the valid password and new ownership
information.
[0215] In one embodiment, each play object is associated with a
card, like an ATM (automated teller machine) card. This card
contains information about the play object or collection of play
objects owned, for example, by an individual. To exchange play
objects, each owner only has to wave the card or place the card
near the master unit or master/host/server to effect the transfer
and enter the appropriate security or PIN information. This way,
owners can have their collection information in one master
card.
[0216] Alternatively, each play object may have its own associated
card containing ownership information about that play object,
similar to having a birth certificate or a car registration
form
[0217] A master unit may handle the transfer of more than one type
or product line of play objects. Meaning that a master unit may
handle various play objects so long as the master unit 1033 (FIG.
10B) is able to read/write information from the RFID tag ICs of the
play objects. This means that play objects may be sold without
corresponding master units 1033. So long as a user has access to an
appropriate master unit, exchanges and transfers may be done.
[0218] In another embodiment, all master units, regardless of the
play-patterns or game processed, can handle exchange and transfer
transactions of all or a number of play objets. This may be done,
for example, by having certain information be stored in these play
objects. In another embodiment, only certain master units handle
this type of transaction, e.g. exchanges and transfers.
[0219] A master unit 1033, handling transfers and exchanges,
generally has an antenna 1032, a display 1042, an RFID
reader/interrogator 1034, a speaker 1040, and an input device
(keyboard) 1044, (microphone) 1052.
[0220] In doing exchanges, for example, the play object or the
container of the play object 1002, 1004 contains the RFID tag IC.
To initiate an exchange, the owner of each respective action figure
enters their user name and password 1050, 1052. The master unit
1033 processes this information. If the information entered is
correct, the RFID tag IC of each respective play object or
container of each respective play object is updated accordingly to
reflect new ownership information.
[0221] Values, such as money value, play currency value, strength,
hit points, and the like are associated with each action figures.
This information and values depends on game or play-pattern designs
and thus may also be accordingly updated during the exchange
function. Information and values may also be updated and revised by
connection via a master unit to a network, the internet, store
point-of-purchase registers, and the like.
[0222] In another method of trading, exchange, or processing of
play object or variable play substance information (e.g. exchange
of play money), each play object 1002, 1004 is associated with a
master control card 1050, 1060. Each play object 1002, 1004 also
contains a unique serial number or any other identity-type
information in its RFID tag IC. The master control card also
contains an RFID tag IC and an antenna. The RFID tag IC also
contains the serial number of the associated play object.
Preferably, the master control card also contains a personal
identification number (PIN) so that unauthorized transfers or trade
are prevented.
[0223] To initiate the process or transfer, the owner of the action
figure, for example, action FIG. 1 (1002), waves or places his or
her master control card 1050 over the transactor master unit 1033.
The owner then is prompted, via a user presentation display, to
enter his or her PIN. The owner enters the PIN via an input device,
such as a keyboard 1044 or microphone (voice commands) 1052. Once
the user enters the proper PIN and is verified by the master unit
1033 by reading the RFID tag IC of the master control card, the new
owner is then prompted to enter a new PIN. The master control card
1050 associated with action FIG. 1 (1002) is then asked to be waved
over the master unit 1033 so that the PIN of the new owner may be
written into the memory of the tag IC. Optionally, action FIG. 1
(1002) may also be asked to be waved over the master unit 1033 so
that information, e.g. transfer history, new PIN, variable play
substance information change, and the like, may be written into the
tag IC of the traded or exchanged action FIG. 1.
[0224] It is also possible that variations on this operation may be
made, for example, no PIN is required, owner personal information
is written into the processed play object, ownership is not changed
but only variable play substance information (e.g. transfer of
virtual play money), additional master control cards are needed,
etc.
[0225] In still another embodiment of the invention, a game or toy
1100 (FIG. 11) includes a master unit in the form of a toy car or
toy moving vehicle and several play objects in the form of cards
1104, 1106, 1108 and three-dimensional objects 1110, 1112, 1114,
with each play object containing one or more RFID tag ICs 1132
within them and a suitable antenna element 1134. The antenna of the
master unit is preferably at the bottom of the plastic car 1102
and/or in the side of the car.
[0226] The game or play pattern is designed such that the vehicle
1102 makes an audio response as it recognizes each play object.
This response, for example, includes "That's the letter `A`" 1104,
"This is a turtle 1106," "That's a triangle," "What a pretty oak
tree" 1110, music, sound effects, and the like.
[0227] In one embodiment, a child pushes or remotely controls the
car 1102 to travel 1122 on a predefined track 1116. The moving
vehicle may also be self-powered. As it travels through the track
1116 and over each card, it recognizes the play objects, 1104,
1106, 1108, and accordingly generates and projects the proper audio
presentation through the car's speakers.
[0228] In another embodiment, a child freely pushes the car 1102 in
an arbitrary path 1124, i.e. without a predefined track. As the car
passes or comes near the play objects 1110, 1112, 1114, the car
generates the appropriate audio response, such as "What a pretty
oak tree" 1110, "Oh, that's the bakery" 1112, "A rabbit!" 1114.
[0229] The car can also make other types of sound effects, besides
speech, as well as activate other effects in the moving vehicle
such as flashing lights, changing speed, turning motor on and off,
and causing moving pieces to move.
[0230] As can be seen from the various embodiments of the
invention, it is feasible that master units and play objects from
one game may be used in another game, so long as data transmitted
can be recognized and understood by the master unit being used.
This means that numerous master unit and play object combinations
may be created with minimal changes to the underlying master unit
circuit and/or program.
[0231] In yet another embodiment of the invention, a game 1200
(FIG. 12) includes a hand-held unit 1203, such as a wand, scanner,
or waver master/host/server or master unit, with an RFID
reader/interrogator circuit and antenna, or portions thereof,
within it. The hand-held unit may be in various three-dimensional
forms. The antenna 1213 is around the open viewport of the
hand-held unit 1203. The master unit toy 1203 also includes a
microcontroller, an RFID reader/interrogator, and a voice/sound
generator. The play objects each contain an RFID tag IC and at
least one antenna.
[0232] As the child waves the hand-held unit 1203 over the play
objects 1202-1214 with the RFID hand-held master unit ICs,
appropriate responses are generated. Such response may include,
"That's the letter W" 1202, "That's a black rabbit" 1204, "That's a
star" 1206, "That's a green turtle" 1208, and "That's an airplane"
1210. These responses may be varied. The user presentation may also
be varied, such as there could be additional visual presentation or
visual effects displayed by the hand-held scanner unit, the
hand-held unit can vibrate as each play object is recognized,
pieces of the hand-held unit may move (e.g. dance), and the
like.
[0233] Another play pattern can be that moving the RFID-tagged play
object close to the hand-held unit or scanner 1203 will activate a
price charge in a toy cash register or store play set, like a
retail supermarket check-out, etc.
[0234] The hand-held unit may also take another form. Instead of a
wand, the master unit toy may be in the form of a glove, a
hand-held puck or pod, a long stick, a rod, a pencil, and the
like.
[0235] The antenna/energy and data-coupling element is located in
the tip or end of the wand/rod--hand-held element. This. "sweet
spot" can be waved and scanned over the tags.
[0236] Physical touching of the wand sensing element to the toy or
game itself is also possible, for play pattern and play action
value. The physical contact, however, is not required for signal
and energy coupling, but is yet another means of play pattern in
addition to waving, scanning, and other signal exchange
methods.
[0237] In another embodiment, the master unit 1223 (FIG. 12B) is
not entirely housed in one object or toy. In this embodiment, the
antenna 1233 and the RFID reader/interrogator are in the hand-held
unit itself. Other components of the master unit, however, such as
the microcontroller 1241 and the voice/sound synthesizer 1239 are
in another unit such as a box 1237. Power source may also be stored
in this box 1237. The wand 1223 and the box 1237 are connected by a
wired connection 1225. Thus, it is possible that the master unit
engine be partitioned and housed in several entities and
locations.
[0238] Due to RF circuit design, it is preferable that the RFID
reader/interrogator circuit and the antenna or coupling element be
in close physical proximity with each other so as to minimize
detuning effects.
[0239] In an alternative embodiment, a play object 1250 (FIG. 12C),
in this example a toy doll, contains a number of RFID tag ICs and
antennas 1252. Each RFID tag IC is associated with an antenna to
identify a particular location or body part of the doll.
[0240] For example, if the hand-held unit 1203 is placed near or
over certain areas, appropriate user presentation is generated.
Examples of such response include "This is my nose" 1252, "This is
my right arm" 1254, "This is my right hand to hold a bottle" 1256,
"This is my right foot" 1258, and "This is my left foot" 1260.
Instructions such as "Touch my nose," "Tickle my left foot," "Touch
my arm," and the like may also be included as part of the game.
This play object may be used to teach children various body
parts.
[0241] This play object may also be a game board with a number of
RFID tag ICs, or any two- or three-dimensional play object with a
number of RFID tag ICs in various locations of the object. When the
movable hand-held unit is waved on this RFID-tagged locations, game
instructions may be given in accordance with the game or play
pattern played at that time. This hand-held unit thus may be
fashioned as to look like a game controller or a playing piece.
[0242] In yet another embodiment of the invention, the master unit
toy 1300 is a loop-like device. The game is designed such that
various play objects are flown through the loop 1302. This loop
also contains the antenna associated with the RFID
reader/interrogator 1304. A voice/sound synthesizer 1306, a speaker
1310, a microcontroller 1308 are also housed in this toy unit.
[0243] To play this game, a child flies the RFID-tagged action
FIGS. 1132-1356 through the loop. The master unit toy 1302
accordingly generates the proper user presentation, such as audio
responses. For example, the master unit says "Hey, It's Superman,"
"Show me Batman," or "It a Firefighter," when the play objects
1354, 1356, 1352 are respectively flown into the loop.
[0244] When the master unit detects more than one action FIG. 1352,
1354, 1356, for example, near the loop, a battle play pattern may
be initiated. For example, a play by play story, for example,
"Superman took some three points damage," "Batman's strength went
up by two," and the like may be presented to the users. The RFID
tag ICs of respective action figures are also accordingly updated
to reflect new or updated information due to the play that has
ensued.
[0245] In another embodiment, the master unit toy 1333 is in table
or box-like form. This toy 1333 includes an antenna 1332, an RFID
reader/interrogator 1334, a microcontroller 1336, a speech/sound
synthesizer 1338, and a speaker 1340. As the play objects are flown
or passed over the table 1333 the appropriate user presentation and
update to the appropriate RFID tags are presented.
[0246] User presentation as applied to the many embodiments of this
invention is not limited to audio presentation. Other forms, such
as visual, tactile, and olfactory presentation may be incorporated
in the master units. Appropriate components to handle such user
presentation have to be incorporated in the master units.
[0247] The various embodiments of the invention discussed herein
generally works in a game environment that includes a
master/host/server or master unit and at least one play object with
an. RF tag IC. The game environment generally works in such a way
that communication, particularly, data exchange, is generally
established when the play object is in at least one detection area
of the master unit for the minimum time required to complete a
successful RFID transponder data exchange, read, or read/write
operation. This means that communication is established even if the
master unit is stationary and the play object is stationary, even
if the master unit is stationary and the play object is in motion
(e.g. waving or passing of an RFID-tagged flash card or play object
in front of or around the dolls shown in FIG. 1), even if the
master unit is in motion and the play object is stationary, and
even if the master unit and the play object are both in motion.
[0248] To explain the above-mentioned features of the invention,
another embodiment of the invention is herein discussed and shown
in FIG. 14A. In this game environment, a master unit vehicle 1402,
such as a tractor, may be moved by a child.
[0249] This vehicle 1402 contains an RFID reader/interrogator
circuit and an antenna. This antenna is preferably placed at the
bottom and/or side of the tractor. The RFID reader/interrogator is
hidden inside the vehicle. A microcontroller containing a program
and a speech synthesizer are also housed in this vehicle.
[0250] The tractor 1402 interacts with play objects 1404-1410.
These play objects, for example, may represent things that a person
sees in a farm. These objects may be placed by a parent around a
young child so that the young child can play with the tractor and
these play objects.
[0251] These play objects 1404, 1406, 1408, 1410 include RFID tag
ICs and associated antennas. The RFID tag ICs contain information
identifying the object. This set of information may include serial
number, information to be digitally synthesized, and object name
(e.g. "cow," "pig," or "sheep").
[0252] In one play pattern, when a child moves the tractor master
unit 1402 close to a play object, for example, the cow 1404 so that
a communication 1414 is established between the RFID
reader/interrogator of the tractor and the RFID tag IC of the cow,
the tractor responds, for example, by saying "Your tractor is in
front of a cow. `Moo moo`" 1412. In this scenario, the cow is
stationary/still while the tractor is in motion (FIG. 14B).
[0253] Questions and instructions may also be part of the play
pattern. Instructions may be given such as "Drive the car to the
pig." The master unit may then determine if such instruction was
properly carried out.
[0254] When a communication 1414 is established, the RFID tag of
the cow 1404 transmits and receives information in the form of data
bit streams to and from the tractor 1402. The RFID tag receives
their operating power from the RF energy transmitted by the master
unit at the same time as data exchange occurs.
[0255] This information is then processed by the microcontroller
under the control of a program. Appropriate responses, as coded in
the program, are accordingly generated. For example, the speech
synthesizer may instruct the microcontroller, in conjunction with a
speech/sound synthesizer, to generate or synthesize a statement
1412.
[0256] Alternatively, the child may also move the play object, e.g.
cow 1404, near the tractor 1402 so that a communication 1414
between the cow and tractor is established (FIG. 14C). The tractor
at this point is in a fixed or stationary position. The appropriate
response 1412 is generated similar to the scenario above.
[0257] The child may also hold the tractor 1402 and the cow 1404 in
each hand and slowly move them close together (FIG. 14D). Even
though the tractor and the cow are in motion, so long as a
communication is established--i.e. the cow is in a detection
position relative to the tractor, the appropriate response 1412 is
generated by the tractor.
[0258] Furthermore, even if the tractor and cow are stationary
(FIG. 14E), so long as they are placed in such a way that they
communicate with each other, the tractor would recognize the cow
and generate the appropriate response. The number of times a
response 1412 is repeated depends on the instructions contained in
the program controlling the microcontroller.
[0259] When a master unit toy, in this embodiment--the tractor
1402, is in a position to communicate with the object, the tractor
1402 is able to continuously recognize the object, e.g. the cow
1404. How often and how continuous this recognition occurs may
depend on power-saving mechanisms contained in the master unit
toy.
[0260] In another embodiment of the invention, a master unit
vehicle interacts with a mat or a board displaying various artwork
or pictures painted or drawn by various artists. Each artwork is
associated with an RFID tag IC and at least one antenna.
[0261] A child may move the vehicle over the mat and when the
vehicle is over or passes over an artwork (i.e. a communication is
established), the vehicle recognizes the artwork and responds
accordingly with voices/sounds or any other responses instructed by
the program controlling the microcontroller of the master unit. It
may for example identify the artwork, for example, "Van Gogh,
Starry Night."
[0262] The cards may also contain shapes, numbers, and the like.
The play-pattern may also involve just counting the cards
recognized, for example, saying "We have seen three stars and two
squares."
[0263] In still other embodiments of the invention (FIG. 15), a
master/host/server or master unit is embodied in several devices
such as in a cellular phone 1502, a videophone 1504, or a computer
1506. These devices have a similar "engine" 103 as the dolls
previously described (FIGS. 1A and 1B). These various devices may
be located in several places, such as the place where the play
objects are purchased, the user's home, toy stores, etc. These
devices also have a similar RFID reader/interrogator engine as the
dolls, toys, and games previously described (e.g. FIGS. 1 through
5).
[0264] In one game play-pattern, play objects such as POKMON.RTM.
cards with RFID tag circuits are read by such game units 1502,
1504, and 1506. The RFID tag ICs include read and/or write memory
devices and may contain identity numbers, such as serial numbers,
as well other-information about that card. It is similar to the
play objects 108 in FIG. 2.
[0265] When these cards are read by the RFID reader/interrogator
contained in these game units 1502, 1504, 1506, information about
the cards are presented to the users, preferably in both visual and
audio form. The information provided to the users may be those
directly contained in the tag ICs of the cards themselves or may be
provided as part of the program contained in the
microcontroller.
[0266] The program may also contain other instructions such as
role-playing game instructions enabling the characters represented
by the cards to compete in duels and in car races, embark in
adventure fantasies, and other play-pattern activities and
functions.
[0267] Play objects in this scenario thus may be purchased from
various vendors and locations. A user may use any master unit that
is programmed to recognize and present information about the play
objects. The user is thus not compelled to purchase a master unit,
but may borrow available master units, if so desired.
[0268] Children, and even adults, love to collect things such as
cards, action figures, cars, and accessories. These collectibles
may be made in the form of play objects containing RFID tag ICs,
including at least one antenna. This way, when children are showing
off their price collection, even if more than one child owns the
same collectible item, e.g. the same POKMON.RTM. card, the
ownership of each card is easily identifiable.
[0269] Other uses and benefits of keeping information as part of
the play object are apparent and are handled by several embodiments
of this invention.
[0270] A board game 1600 (FIG. 16) is yet another embodiment of the
invention. This board game may have one to four players, or more,
depending on the game rules programmed and selected for play. Each
player has his or her own set of coins or tokens each containing a
read only or read/write RFID tag IC (play objects). The objective
is to remove other coins off the game board or table. The board
game is usually placed on a table.
[0271] Each player puts his or her coins on the table and flips a
coin in turn. If a player succeeds in removing other players'
coins, those coins are now his or her to keep.
[0272] The board game 1600 generally contains a microcontroller
1619, a speech/sound synthesizer 1620, a speaker 1622, an RFID
reader/interrogator 1616, and an antenna 1624. A control program
controlling the microcontroller is also available. There could be
one RFID reader/interrogator 1616 in each control box 1616, i.e. in
each corner of the board. An antenna is associated with each RFID
reader/interrogator 1604.
[0273] Variations on the number and placement of RFID readers 1604
may be implemented based on the play-pattern desired. For example,
there could be more than four RFID readers on the board, a number
of antennas are placed in the middle of the playfield 1610, and the
like. There could also be four separate antennas, one located in
each corner of the board. Each area may have a separate antenna,
which can be multiplexed by a single interrogator. This way, the
game can be played knowing which specific objects are in which
specific location in the game board.
[0274] An example of coins that may be used is specialized
POKMON.RTM. coins. These coins each contain an RFID tag IC and
antenna. One of the play patterns involves having an audio response
when a user puts a coin down or flips a coin. For example, when a
player puts a Mew coin, the speaker projects "Mew!" When a Pikachu
coin is flipped into the board, the user hears "Pika!." When a user
flips a coin, the user hears "Hooray!"
[0275] The play pattern may also be such that within the game, each
coin grows up and gets special powers permanently. This can be done
by reading and updating the RFID read/write tag ICs of appropriate
coins.
[0276] For example, special powers may be added or increased if the
experience points of the coin reach a certain predetermined value.
This value is controlled by the game program.
[0277] During the start of the game or the new introduction of
coins in the game, the coins, for example, are updated with initial
value, such as initial hit points, power points, and special
points. During the course of the game, for example, if a coin is
detected in the out of field zone 1614 (detected by an appropriate
antenna placed in this area), hit points are decreased, for
example, by ten points. When the hit points become zero, the coin
"faints" or loses.
[0278] If a coin is detected by an antenna placed at or near the
danger zone, sound effects may also be played. Variations on
different board games play pattern rules and design may be
implemented using the features of the inventions described
herein.
[0279] In still another embodiment of the invention, a board game
1700 (FIG. 17) has a number of RFID tag ICs 1722 placed within the
board identifying locations, letters, shapes, pictures, symbols,
depictions, animals, fruits, or whatever is desired in the play
pattern of the game. The play pattern of this game, for example, is
the placing of hand-held units, such as three-dimensional items or
tokens 1704, 1702 over or near the printed pictures 1720 on the
board 1730. This could be used as part of a guessing game, an
adventure game, a role-playing game, and any other play pattern
desired.
[0280] These hand-held three-dimensional items or detectors 1704,
1702 are used to interact or play with the board and act as
master/host/server units. Each three-dimensional detector 1704,
1702 generally includes an RFID reader/interrogator 1712, an
antenna 1714, a processor, a program controlling the processor, and
a speaker to project sound, speech, and sound effects. Each
detector functions as a master unit such that placing or moving the
item over a board location triggers the detector to respond with
programmed sounds, music, and the like.
[0281] An RFID tag IC 1722 and an antenna 1724 are present
underneath each printed depiction to identify the location or the
picture. This way, when the detector master units 1702, 1704 are
placed on the game board, the detectors can respond by saying if
the tokens are placed in the correct locations. Variable play
substance information, such as the number of times a detector is
placed properly on a picture, is written into the memory associated
with the RFID tag IC. In general, the detectors move about the game
board and can detect tags at certain locations, thus affecting game
play, variable play substance information, points, sounds, visual
presentation (if available), and other play patterns of the
game.
[0282] The present invention has been described above in terms of
preferred embodiments so that an understanding of the invention can
be conveyed. There are, however, many configurations, forms,
play-pattern environments, rules and logic, and circuit designs for
master/server/host toys and play objects, not specifically
described herein but to which the present invention is still
applicable.
[0283] The foregoing illustrates preferred embodiments of the
invention by way of example, not by way of limitation. For example,
the RFID reader/interrogator and/or the RFID tag may come from
other manufacturers, the play-patterns modified to accommodate
different set of play-patterns or game rules, the play objects are
housed in different forms (e.g. toy lamp, toy desk, toy chair,
etc.), a different set of play objects is used, information
contained in the RFID tags differs from those described herein, the
game board is different, or the user presentation differs from the
one described herein. A person skilled in this field will recognize
that such variations may exist without departing from the
principles of the invention. The present invention should therefore
not be seen as limited to the particular embodiments described
herein, but rather should be understood to have wide applicability
with respect to master/server/host toys and play objects. All
modifications, variations, or equivalent arrangements and
implementations that are within the scope of the attached claims
should therefore be considered within the scope of the
invention.
