application screens of the mobile device 100.
[0043] More particularly, the mobile device 100 may further include
a solar photovoltaic panel (not shown), a motion sensor unit (not
shown), and a location-based communication module (not shown).
[0044] The solar photovoltaic panel generates electric power by
converting solar radiation into direct current electricity in order
to charge a battery of the mobile device 100. The solar
photovoltaic panel is arranged on one or more sides of the mobile
device 100.
[0045] The motion sensor unit may be formed of an acceleration
sensor, a gyro sensor, a geomagnetic sensor, and the like. The
motion sensor unit detects a user's motion made against the mobile
device 100, creates a motion detection signal, and delivers the
motion detection signal to the control unit 160. For instance, if
the motion sensor unit is formed of the acceleration sensor, the
motion detection signal includes data about changes in
acceleration. The control unit 160 recognizes a user's motion
through the motion detection signal and performs a corresponding
function.
[0046] The location-based communication module receives and
transmits a signal required for determining information about a
current location of the mobile device 100. The location-based
communication module may include a Global Positioning System (GPS)
module, a Bluetooth communication module, an Infrared communication
module, a Zigbee communication module, a WIFI communication module,
and the like.
[0047] If formed of the GPS module, the location-based
communication module receives GPS signals from GPS satellites and
sends the GPS signals to the control unit 160. Then the control
unit 160 determines a current location of the mobile device 100
through the GPS signals. If formed of the Bluetooth communication
module, the Infrared communication module, or the Zigbee
communication module, the location-based communication module
establishes a communication channel with another communication
module located in the vicinity and sends information about the
established channel to the control unit 160. Then the control unit
160 ascertains a communication module on the other end of the
channel and determines a rough location of the mobile device 100.
If formed of the WIFI communication module, the location-based
communication module connects with a neighboring Access Point (AP)
and sends information about the connected AP to the control unit
160. Then the control unit 160 ascertains the connected AP and
determines a rough location of the mobile device 100.
[0048] The control unit 160 performs a function to control all of
the operations of the mobile device 100. According to an exemplary
embodiment of the present invention, the control unit 160 measures
recharging amount or time of the battery which is charged by the
solar photovoltaic panel, and controls the display unit 150 to
display the measured amount or time thereon. If the measured amount
or time is more than a predefined critical amount or time, the
control unit 160 transitions the state of the mobile device into an
executable state of a specific application.
[0049] When a power-off command is inputted through the input unit
140, the control unit 160 checks a current level of the battery and
turns off the power. Additionally, when a power-on command is
inputted through the input unit 140, the control unit 160 turns on
the power and checks a current level of the battery. Then the
control unit 160 measures the recharging amount or time of the
battery by comparing a battery level determined before the
power-off with a battery level checked after the power-on.
[0050] In another exemplary embodiment of the present invention,
the control unit 160 receives instructions to enter into an eco
mode of the mobile device from the input unit 140 and controls the
display unit 150 to be adapted to the eco mode. More specifically,
in the eco mode, the display unit 150 may increase a black portion
of a currently displayed screen view or may reduce the brightness
of the screen view, while keeping the shape of the screen view.
Alternatively, in a case where the screen view contains several
icons displayed thereon, the display unit 150 may omit parts of
icons from the screen view or may change the shape of each icon
from a full image to an outlined image.
[0051] In this exemplary embodiment, the display unit 150 may
display a specific icon used for an entry into the eco mode. When
such an icon is selected through the input unit 140, the control
unit 160 determines that instructions to enter into the eco mode
are inputted. Alternatively, when receiving a particular command to
enter into a specific screen view defined as the eco mode through
the input unit 140, the control unit 160 may determine that
instructions to enter into the eco mode are inputted.
[0052] In still another exemplary embodiment of the present
invention, the control unit 160 executes several applications in a
multi-tasking manner. In this case, the control unit 160 enables
the display unit 150 to display a list of applications and to
display battery consumption of each application in the list.
Additionally, the control unit 160 enables the display unit 150 to
display an icon for quitting each or all of executed applications
and to display an icon for an entry into a battery check menu.
Furthermore, the control unit 160 enables the display unit 150 to
display different colors or animation images with different speeds
for respective applications according to battery consumption. Also,
if the icon for an entry into the battery check menu is selected
through the input unit 140, the control unit 160 enables the
display unit 150 to display a list of executable applications and
battery consumption of each application. In the battery check menu
screen, the control unit 160 enables the display unit 150 to
display application quit icons for the currently executed
applications among executable applications.
[0053] In still another exemplary embodiment of the present
invention, the control unit 160 calculates the number of user's
steps by using the motion sensor unit and creates a virtual item
depending on the number of user's steps. In addition, the control
unit 160 finds a current location of the mobile device 100 by using
the location-based communication module and enables the display
unit 150 to display a virtual world map and to display a virtual
item at the current location in the virtual world map.
[0054] In still another exemplary embodiment of the present
invention, the control unit 160 finds a current location of the
mobile device 100 by using the location-based communication module,
sends a request for environmental information about the current
location to a server through the RF unit 110, receives the
requested environmental information, and displays the requested
environmental information on the display unit 150. Also, the
control unit 160 classifies the environmental information according
to at least one regional level and displays such regional levels on
the display unit 150. If one of regional levels is selected, the
control unit 160 enables the display unit 150 to display the
environmental information about the selected regional level.
[0055] Described hereinafter is a method for providing an
eco-friendly User Interface (UI) of the mobile device 100 discussed
above. Five exemplary embodiments in connection with such methods
are fully discussed.
[0056] A first exemplary embodiment of the present invention
relates to a method for providing a user interface that gives a
user motivation to frequently use a solar charge system. This
exemplary embodiment is described below with reference to FIG. 2 as
being applied to the mobile device 100, which has solar charge
capabilities.
[0057] FIG. 2 is a flow diagram illustrating a method for providing
an eco-friendly UI in accordance with the first exemplary
embodiment of the present invention. In the first exemplary
embodiment, the mobile device 100 has implemented therewith the
solar photovoltaic panel discussed above.
[0058] Referring to FIGS. 1 and 2, the solar panel (not shown)
starts a solar charge in step 201. That is, the solar panel
receives solar energy and converts the solar energy into electrical
energy to charge a battery. Then the control unit 160 determines
whether a power-off command is inputted through the input unit 140
in step 202. If no power-off command is inputted, the control unit
160 measures a recharging amount in step 203 and enables the
display unit 150 to display the recharging amount in step 204.
[0059] In this exemplary embodiment, the recharging amount may be
represented using a `mAh` or `W` unit. Alternatively, the
recharging amount may be represented as a fossil fuel (e.g., coal
or oil) image or a tree image. Also, a fossil fuel image or a tree
image may be expressed together with the amount of fossil fuel or
trees which can be conserved by performing a solar charge. For
instance, in a case of a coal image, the amount of fossil fuel may
be expressed using a weight unit such as gram or kilogram. In a
case of an oil image, the amount of fossil fuel may be expressed
using a volume unit such as milliliter or liter. The amount of
trees may be expressed using a weight unit, a volume unit or the
number of trees.
[0060] The recharging amount may be represented by the day, week,
month or year. The control unit 160 may record a cumulative
recharging amount that has been added after the launch of the
mobile device 100. If a reset function is available, the control
unit 160 may restart recording a cumulative recharging amount after
receiving a reset command through the input unit 140.
[0061] In an alternative exemplary embodiment of the present
invention, the control unit 160 may measure a recharging time
instead of the recharging amount in the step 203 and may enable the
display unit 150 to display the recharging time in the step 204.
The recharging time may be represented using a time unit such as
hour, minute or second.
[0062] Next, the control unit 160 determines whether the measured
recharging amount is more than a predefined critical amount stored
in the memory unit 130 in step 205. The predefined critical amount
corresponds to the condition that the control unit 160 executes a
specific application which may be an eco-friendly program stored in
the memory unit 130. Such a specific application is set to be
executed when the recharging amount satisfies a given
condition.
[0063] If the measured recharging amount is more than the
predefined critical amount, the control unit 160 transitions the
state of the mobile device 100 into an executable state of a
specific application in step 206. For instance, a specific
application may be an item fostering application, and an item may
be a tree, a flower, or the like. The control unit 160 executes the
item fostering application and enables the display unit 150 to
display a seed or root image. During a solar charge, the control
unit 160 measures the recharging amount and thereby changes a
displayed item. For instance, under the control of the control unit
160, the display unit 150 continuously displays a process of growth
from a seed or root into a tree or flower.
[0064] In a certain exemplary embodiment, two or more critical
amounts may be stored in the memory unit 130. In this case, the
control unit 160 measures the recharging amount and, if the
measured amount reaches the first critical amount, transitions the
state of the mobile device 100 into an executable state of a
specific application. Then if the measured amount reaches the
second critical amount, the control unit 160 creates a new item and
displays it on the display unit 150. For instance, when the
measured amount reaches the second critical amount, the control
unit 160 enables the display unit 150 to further display a new root
image near a growing tree image. Also, whenever the measured amount
reaches another critical amount, the control unit 160 may
continuously create a new item and display it on the display unit
150. As a result, several trees can be displayed together on the
display unit 150. Alternatively, whenever the measured amount
reaches another critical amount, the control unit 160 may remove a
displayed image from the display unit 150 and replace it with a new
one. For instance, when the measured amount reaches the second
critical amount, the control unit 160 may remove an existing tree
image and display a fossil fuel image.
[0065] In a certain exemplary embodiment, the recharging amount may
be converted into a point and used as a mean of payment for a
content purchase. In this case, the control unit 160 enables the RF
unit 110 to access a content providing server and transmits data
about a cumulative recharging amount to the content providing
server. Then the content providing server converts the received
data into a corresponding point and returns it to the mobile device
100. So, a user of the mobile device 100 can purchase desired
content with the received point. Preferably, purchasable content
may be eco-friendly content such as a tree or flower image or
eco-related music content.
[0066] Meanwhile, if a power-off command is inputted in the step
202, the control unit 160 checks a current battery level in step
207 and turns off the power in step 208. Next, the control unit 160
determines whether a power-on command is inputted through the input
unit 140 in step 209. If a power-on command is inputted, the
control unit 160 turns on the power in step 210 and checks a
current battery level in step 211. Also, the control unit 160
measures a recharging amount by comparing a battery level checked
before power-off with a battery level checked after power-on in
step 212. Thereafter, the control unit 160 performs the step 204 in
order to display the measured recharging amount by controlling the
display unit 150.
[0067] FIG. 3 is a screen view illustrating an eco-friendly UI
provided by the method in accordance with the first exemplary
embodiment of the present invention.
[0068] Referring to FIG. 3, screen view [a] exemplarily shows the
representation of the recharging amount. As shown, this screen view
offers a menu in which a user can monitor the recharging amount by
the day, week and month. This screen view displays the recharging
time using `hour` as a unit as well as the recharging amount
(expressed as `production` in the drawing) using `mAh` as a unit.
Also, this screen view further displays a graph that shows
variations of the recharging amount by the week in a given month.
In addition, this screen view further displays an icon `growing
trees` which corresponds to an execution icon of a tree fostering
application. This icon `growing trees` may not appear until the
recharging amount reaches a predefined critical amount. This icon
`growing trees` indicates that the mobile device 100 is turned to
the state capable of executing the tree fostering application.
[0069] In FIG. 3, screen view [b] exemplarily shows an execution
screen of the tree fostering application. As shown, this screen
view includes a numeral value of the recharging amount and a tree
growing image. During a solar charge, the control unit 160 checks
the recharging amount and, based thereon, changes the numeral value
of the recharging amount and the shape of the tree growing image.
Also, this screen view displays a `set idle screen` icon and a `set
lock screen` icon. The `set idle screen` icon corresponds to an
icon for setting the idle screen to the execution screen of the
tree fostering application. The `set lock screen` icon corresponds
to an icon for setting the lock screen to the execution screen of
the tree fostering application. These icons allow a user to
directly change the idle screen or the lock screen without entering
into a `screen set menu`. If the execution screen of the tree
fostering application is set as the idle screen, a user can always
see a current value of the recharging amount and a real-time tree
growing image.
[0070] As discussed heretofore, the mobile device 100 according to
the first exemplary embodiment of the present invention may offer a
sensible feedback to a user, depending on the recharging amount or
time. This may give a user a motivation to often use a solar charge
system.
[0071] A second exemplary embodiment of the present invention
relates to a method for providing a user interface that allows the
mobile device 100 to reduce power consumption. This exemplary
embodiment is applied to the mobile device 100 having an eco mode
that is set to reduce power consumption in comparison with a normal
mode.
[0072] The control unit 160 determines whether a command to enter
into the eco mode is inputted from the input unit 140. In one case,
the control unit 160 may output an icon for an entry into the eco
mode on the display unit 150 and determine whether that icon is
selected through the input unit 140. In this case, the input unit
140 may be formed of a touch panel. In another case, when the input
unit 140 has a function key used for an entry into the eco mode,
the control unit 160 may determine whether that key is selected
through the input unit 140.
[0073] In a case where the idle screen, the menu screen, the
application screen, etc. are composed of several faces, one of the
faces may be set for the eco mode screen. In this case, the control
unit 160 enables the display unit 150 to display one of several
faces composing such a screen and determines whether a command to
enter into the eco mode is inputted from the input unit 140. If the
input unit 140 and the display unit 150 are formed of a touch
screen and if a user inputs a touch-based given action (e.g., a
drag or flick) on the touch screen, the control unit 160 may change
a displayed screen. If the inputted action instructs an entry into
the eco mode, the control unit 160 displays the eco mode screen on
the display unit 150 and transitions the mobile device 100 into the
eco mode.
[0074] After the mobile device 100 is turned to the eco mode, the
control unit 160 may increase a black portion of a currently
displayed screen as compared to that in the normal mode. Normally,
color used in the screen may affect power consumption. That is,
black consumes the lowest power, and power consumption is increased
in the order of green, red, blue and white. The memory unit 130
stores different color information about the same screen, depending
on the normal mode and the eco mode. In the eco mode, the control
unit 160 retrieves corresponding color information from the memory
unit 130 and applies it to the display unit 150.
[0075] FIG. 4 is a screen view illustrating an eco-friendly UI
provided by a method in accordance with the second exemplary
embodiment of the present invention.
[0076] Referring to FIG. 4, screen view [a] shows a background
screen in the normal mode. This background screen is composed
chiefly of red, blue and white. On the other hand, screen view [b]
of FIG. 4 shows a background screen in the eco mode which is
composed chiefly of black. The control unit 160 enables the display
unit 150 to display a relatively increased black portion of the
screen in the eco mode, thus reducing power consumption.
[0077] Alternatively, the control unit 160 may reduce the
brightness of the screen. Normally, the brightness of the screen
may affect power consumption. That is, the higher brightness
consumes more power. In this case, the memory unit 130 stores
different brightness information about the same screen, depending
on the normal mode and the eco mode. In the eco mode, the control
unit 160 retrieves corresponding brightness information from the
memory unit 130 and applies it to the display unit 150.
[0078] Also, the control unit 160 may offer fewer icons to the
display unit 150 in the eco mode than those offered in the normal
mode. Normally the number of icons displayed on the screen may
affect power consumption. That is, the fewer icons consume much
less power. In this case, the memory unit 130 stores different icon
number or arrangement information about the same screen, depending
on the normal mode and the eco mode. In the eco mode, the control
unit 160 retrieves corresponding icon number or arrangement
information from the memory unit 130 and applies it to the display
unit 150.
[0079] FIG. 5 is a screen view illustrating another eco-friendly UI
provided by the method in accordance with the second exemplary
embodiment of the present invention.
[0080] Referring to FIG. 5, screen view [a] shows a menu screen in
the normal mode. This menu screen contains sixteen icons. On the
other hand, screen view [b] of FIG. 5 shows a menu screen in the
eco mode which contains nine icons. The control unit 160 enables
the display unit 150 to display relatively fewer icons in the eco
mode, thus reducing power consumption.
[0081] Also, the control unit 160 may change the shape of each icon
from a full image to an outlined image in the eco mode. Normally
the outlined image (i.e., an empty image surrounded with a line)
may consume less power than the full image. In this case, the
memory unit 130 stores both a full image and an outlined image for
the same image, depending on the normal mode and the eco mode. In
the eco mode, the control unit 160 retrieves the outlined image
from the memory unit 130 and applies it to the display unit
150.
[0082] FIG. 6 is a screen view illustrating still another
eco-friendly UI provided by the method in accordance with the
second exemplary embodiment of the present invention.
[0083] Referring to FIG. 6, screen view [a] shows a menu screen in
the normal mode. This menu screen contains icons each of which is
formed of a full image. On the other hand, screen view [b] of FIG.
6 shows a menu screen in the eco mode which contains icons formed
of outlined images. The control unit 160 enables the display unit
150 to change the shape of each icon from the full image to the
outlined image in the eco mode, thus reducing power
consumption.
[0084] Meanwhile, if the mobile device 100 enters into the eco mode
while several applications are being executed in a multi-tasking
manner, the control unit 160 may quit one or more of the executed
applications. Here, the quitted applications may be higher
power-consuming applications or predefined applications. In a
certain exemplary embodiment, the mobile device 100 may have an eco
mode set menu which may contain a menu item for selecting
applications to be quitted in the eco mode. Therefore, by using
such a menu, a user can select at least one application to be
quitted in the eco mode. Selected data is stored in the memory unit
130. When receiving a command to enter into the eco mode from the
input unit 140, the control unit 160 retrieves the stored data from
the memory unit 130 and, based thereon, quits the selected
applications.
[0085] Additionally, in a case where the mobile device 100 has two
or more communication modules, the control unit 160 may quit one or
more of the running modules in the eco mode. More specifically, the
mobile device 100 may have a Bluetooth communication module, a WIFI
communication module, a GPS communication module, and the like. In
this case, if the mobile device 100 enters into the eco mode, the
control unit 160 may selectively quit the running communication
modules. Here, the quitted modules may be higher power-consuming
modules or predefined modules. The eco mode set menu may contain a
menu item for selecting communication modules to be quitted in the
eco mode. Therefore, by using such a menu, a user can select at
least one communication module to be quitted in the eco mode.
Selected data is stored in the memory unit 130. When receiving a
command to enter into the eco mode from the input unit 140, the
control unit 160 retrieves the stored data from the memory unit 130
and, based thereon, quits the selected modules.
[0086] As discussed heretofore, the mobile device 100 according to
the second exemplary embodiment of the present invention may offer
a user interface adapted to an entry into the eco mode with lower
power consumption. The user interface for an entry into the eco
mode is offered in a frequently used screen such as the idle screen
or the menu screen and induces a user to select the eco mode. Power
consumption will be reduced as the mobile device 100 remains in the
eco mode.
[0087] A third exemplary embodiment of the present invention
relates to a method for providing a user interface that allows the
mobile device 100 to reduce power consumption. This exemplary
embodiment is applied to the mobile device 100 having a battery
check menu by which battery consumption for each application is
offered to a user.
[0088] In this exemplary embodiment, the control unit 160
determines whether the battery check menu is selected through the
input unit 140. In one case, the control unit 160 may output an
icon for an entry into the battery check menu on the display unit
150 and determine whether that icon is selected through the input
unit 140. In this case, the input unit 140 may be formed of a touch
panel. In another case, when the input unit 140 has a function key
used for an entry into the battery check menu, the control unit 160
may determine whether that key is selected through the input unit
140.
[0089] If the mobile device 100 executes a single application, the
control unit 160 may enable the display unit 150 to display an icon
for an entry into the battery check menu on the application
execution screen. If the mobile device 100 executes two or more
applications in a multi-tasking manner, the control unit 160 may
enable the display unit 150 to display an icon for an entry into
the battery check menu on the execution screen of one of the
applications or on a multi-tasking application menu screen. Here,
the multi-tasking application menu screen displays a list of
currently executed applications each of which can be represented as
text, an icon or a reduced execution screen.
[0090] When receiving a user's selection of the battery check menu
from the input unit 140, the control unit 160 enables the display
unit 150 to display a battery check menu screen. The battery check
menu screen is composed of a list of executable applications and
battery consumption for each application. The battery consumption
may be represented as a numeral or image. In the former case, the
numeral of the battery consumption may indicate the amount or
percentage of consumed power for each application. In the latter
case, the image of the battery consumption may use a bar,
gradation, etc. Depending on the amount of consumed power, the
image may be varied in size, length and color.
[0091] The control unit 160 may enable the display unit 150 to
display an application quit icon in the battery check menu. Here,
such application quit icons may be displayed only for the currently
executed applications among executable applications. By doing so, a
user can know the executed applications through the battery check
menu screen and can directly quit any application.
[0092] Alternatively, the control unit 160 may enable the display
unit 150 to display the battery check menu screen composed of a
list of currently executed applications and battery consumption for
each application.
[0093] Also, the control unit 160 may enable the display unit 150
to display the battery consumption or corresponding image on the
application execution screen or on the multi-tasking application
menu screen. In this case, the control unit 160 may classify the
levels of battery consumption and define the color of each level.
Then the control unit 160 may enable the display unit 150 to
express an indicator region (in which the application name is
entered) of the application execution screen as different colors
according to the level of the battery consumption. For instance,
the control unit 160 may define four levels of the battery
consumption and assign red, orange, yellow and green to the four
levels, respectively. That is, if the battery consumption of a
certain application is in the first level, the control unit 160
enables the display unit 150 to display the indicator region with
red.
[0094] In a case of the multi-tasking application menu screen being
composed of reduced execution screens, the control unit 160 may
enable the display unit 150 to display the indicator region with
different colors according to the battery consumption. For
instance, if a music application, a web browser application, a
messenger application and a contact history application are being
executed and if these applications have the second, first, third
and fourth levels of battery consumption, respectively, the
indicator regions of these applications are displayed with orange,
red, yellow and green.
[0095] In another case, the control unit 160 may classify the
levels of battery consumption and define an animation speed of each
level. Then the control unit 160 may enable the display unit 150 to
express an animation image with different speeds according to the
level of the battery consumption when displaying the application
execution screen or the multi-tasking application menu screen.
Here, the animation image may be a certain dynamic image such as a
rotating pinwheel image or a running man image. For instance, in a
case of the multi-tasking application menu screen composed of
reduced execution screens, the control unit 160 may enable the
display unit 150 to display the rotating pinwheel image on each
reduced execution screen and vary a rotating speed of the pinwheel
according to the battery consumption.
[0096] Also, the control unit 160 may enable the display unit 150
to display an icon for quitting all executed applications on the
multi-tasking application menu screen. This allows a simultaneous
quick end of executed applications and hence reduces the battery
consumption.
[0097] FIG. 7 is a screen view illustrating an eco-friendly UI
provided by a method in accordance with the third exemplary
embodiment of the present invention.
[0098] Referring to FIG. 7, screen view [a] shows a multi-tasking
application menu screen. As shown, `music`, `browser`, `messenger`
and `contact` applications are being executed and are displayed
with reduced execution screens. In this screen view, the indicator
regions of these applications are displayed with different colors.
More specifically, the indicator region of the `music` application
is displayed with orange, the indicator region of the `browser`
application is displayed with red, the indicator region of the
`messenger` application is displayed with yellow, and the indicator
region of the `contact` application is displayed with green. As
discussed above, each color indicates a distinct level of the
battery consumption of each application. If the level of the
battery consumption becomes higher in the order of red, orange,
yellow and green, a user can know that the `browser` application
consumes the greatest battery.
[0099] Screen view [a] further includes the quit icon for each
application. If any quit icon is selected, the control unit 160
quits the execution of a selected application. Also, this screen
view further includes an `end all` icon used for quitting all
applications being executed in a multi-tasking manner. This icon
allows a simultaneous quick end of all applications without
requiring individual quit inputs in the multi-tasking application
menu screen, thus reducing the battery consumption.
[0100] In FIG. 7, screen view [b] shows another example of the
multi-tasking application menu screen. As shown, an animation image
like a pinwheel is displayed for each application. A rotating speed
of this pinwheel image is expressed. As shown, rotating speeds are
decreased in the order of `browser`, `music`, `messenger` and
`contact` applications. Depending on the rotating speeds, a user
can know that the battery consumption of the `browser` application
is the highest and that of the `contact` application is the
lowest.
[0101] In FIG. 7, screen view [c] shows a battery check menu screen
which is composed of a list of applications and battery consumption
for each application. The battery consumption may be represented as
equally sized and shaped images arranged in a row. The color of the
images may be changed as the number of the images arranged in a row
increases. In this screen view, applications are disposed in a list
according to battery consumption. Therefore, a user can know
through the battery check menu screen that a `3G call` application
consumes the highest battery. Also, an application quit icon is
offered to `browser` and `music` applications. Therefore, a user
can know that the `browser` and `music` applications are currently
executed, and can quit immediately a desired application in the
battery check menu screen by selecting a corresponding quit icon.
Also, a `multitasking` icon is displayed in the battery check menu
screen. This icon is used for a return to the multi-tasking
application menu screen.
[0102] As discussed heretofore, the mobile device 100 according to
the third exemplary embodiment of the present invention may offer
information about battery consumption for each application to a
user in the application execution screen, the multi-tasking
application menu screen and the battery check menu screen. In
addition, the mobile device 100 may offer the application quit icon
for a quick end of selected or all applications.
[0103] A fourth exemplary embodiment of the present invention
relates to a method for providing a user interface that induces a
user's walking and/or other exercise. This exemplary embodiment is
applied to the mobile device 100 having a motion sensor unit (not
shown) and a location-based communication module (not shown). This
exemplary embodiment is described with reference to FIG. 8.
[0104] FIG. 8 is a flow diagram illustrating a method for providing
an eco-friendly UI in accordance with the fourth exemplary
embodiment of the present invention. The mobile device 100 in this
exemplary embodiment includes a step measuring application which
measures a number of a user's steps through the motion sensor unit
and utilizes data about the measured number of steps. In the
following description, it is assumed that the mobile device 100 has
a GPS module as the location-based communication module and has an
acceleration sensor as the motion sensor unit.
[0105] Referring to FIGS. 1 and 8, the control unit 160 determines
whether a command to execute the step measuring application is
inputted from the input unit 140 in step 801. If the execution
command is inputted, the control unit 160 executes the step
measuring application and receives a GPS signal from GPS satellites
through the GPS module in step 802. Next, the control unit 160
finds a current location of the mobile device 100 through the
received GPS signal in step 803. Then the control unit 160 measures
changes in acceleration of the mobile device 100 through the
acceleration sensor in step 804. Also, the control unit 160
calculates the number of user's steps from the measured changes in
acceleration in step 805. The acceleration of the mobile device 100
changes suddenly whenever a user steps forward. Therefore, the
control unit 160 can determine the number of the user's steps by
identifying suddenly changed points of acceleration. Next, the
control unit creates a virtual item corresponding to the number of
user's steps in step 806. The virtual item may be a material, such
as a fossil fuel or trees, for producing energy. After creating the
virtual item, the control unit 160 enables the display unit 150 to
display the virtual item. For instance, if the virtual item is a
tree, the display unit 150 may display trees which may be conserved
according to a user's walking exercise.
[0106] The size or kind of a tree may be varied according to the
number of steps. The memory unit 130 may store data about the size
or kind of a tree corresponding to the number of steps, and the
control unit 160 may determine the size or kind of a tree to be
displayed by checking data stored in the memory unit 130. Also, the
control unit 160 may enable the display unit 150 to further display
the number of user's steps, calories consumed by a user's walking
and/or other exercise, a CO.sub.2 reduction according to a user's
walking and/or exercise, and the like.
[0107] Next, the control unit 160 determines whether an item
utilization function is selected through the input unit 140 in step
807. The item utilization function may be a type of game
application that utilizes the created virtual item.
[0108] If the item utilization function is selected, the control
unit 160 enables the display unit 150 to display a virtual world
map and a current location selection icon in step 808. For
instance, an earth image may be represented as the virtual world
map. Then the control unit 160 determines whether the current
location selection icon is selected through the input unit 140 in
step 809. If the current location selection icon is selected, the
control unit 160 enables the display unit 150 to display the
virtual item at the current location in the virtual world map in
step 810. For instance, if a user is located at Seoul, the control
unit 160 may enable the display unit 150 to display a tree image at
Seoul in the earth image.
[0109] If the current location selection icon is not selected, the
control unit 160 further determines whether a certain location is
selected in the virtual world map through the input unit 140 in
step 811. If any location is selected in the virtual world map, the
control unit 160 enables the display unit 150 to display the
virtual item at the selected location in step 812. For instance, if
a user selects the Amazon in the earth image, the control unit 160
may enable the display unit 150 to display a tree image at the
Amazon.
[0110] In an alternative exemplary embodiment, if the item
utilization function is selected in the step 807, the control unit
160 may immediately perform step 810 to display the virtual item at
the current location in the virtual world map.
[0111] In another exemplary embodiment, the control unit 160 may
perform step 805 before performing the steps 802 and 803. Also, the
control unit 160 may perform step 806 or step 808 before performing
steps 802 and 803.
[0112] The virtual world map containing the virtual item may be
used for the idle screen, etc. Therefore, a user can always
recognize the number of the virtual items, and this may give a user
a motivation for walking and/or exercising.
[0113] Meanwhile, the virtual item may be converted into a point
and used as a means of payment for content purchase. In this case,
the control unit 160 enables the RF unit 110 to access a content
providing server and transmits data about the virtual item to the
content providing server. Then the content providing server
converts the received data into a corresponding point and returns
it to the mobile device 100. Therefore, a user can purchase desired
content with the received point.
[0114] FIG. 9 is a screen view illustrating an eco-friendly UI
provided by the method in accordance with the fourth exemplary
embodiment of the present invention.
[0115] Referring to FIG. 9, screen view [a] shows an example of the
execution screen of the step measuring application. As shown, this
screen is composed of tree images and the number of trees expected
to be saved by a walking and/or exercising. The number of trees
includes the number of trees saved after the execution of the step
measuring application and the total number of saved trees. Also,
this screen further displays a `plant` menu item.
[0116] Screen view [b] is offered when a user selects the `plant`
menu item. This screen view corresponds to the item utilization
function screen discussed above. As shown, this screen contains an
earth image and a `plant current location` icon for selecting the
current location. If this icon is selected when a user is located
at Seoul, the control unit 160 may enable the display unit 150 to
display a tree image at Seoul in the earth image. On the other
hand, if a user selects any other location in the earth image, the
control unit 160 may enable the display unit 150 to display a tree
image at the selected location. Screen view [c] is offered when a
user selects a location corresponding to the Amazon, and thus
displays the text `plant in Amazon`.
[0117] As discussed heretofore, the mobile device 100 according to
the fourth exemplary embodiment of the present invention may offer
functions to measure the number of user's steps, to create the
virtual item according to the measured number of steps, and to
utilize the created virtual item. In particular, the virtual item
may be automatically displayed at a user's current location in the
virtual world map. This exemplary embodiment may give a user
motivation for a walking and/or exercising.
[0118] A fifth exemplary embodiment of the present invention
relates to a method for providing a user interface that allows a
user to continuously recognize environmental issues. This exemplary
embodiment is applied to the mobile device 100 having a
location-based communication module (not shown). This exemplary
embodiment is described with reference to FIG. 10.
[0119] FIG. 10 is a flow diagram illustrating a method for
providing an eco-friendly UI in accordance with the fifth exemplary
embodiment of the present invention. In this exemplary embodiment,
the mobile device 100 is configured to have an eco widget that is a
certain graphic displayed on the idle screen and functions as an
icon for the execution of an eco-friendly application. In the
following description, it is assumed that the mobile device 100 has
a GPS module as the location-based communication module.
[0120] Referring to FIGS. 1 and 10, the control unit 160 determines
whether the eco widget is selected through the input unit 140 in
step 1001. If the eco widget is selected, the control unit 160
executes a specific application corresponding to the eco widget and
receives a GPS signal from GPS satellites through the GPS module in
step 1002. Next, the control unit 160 finds a current location of
the mobile device 100 through the received GPS signal in step 1003.
Then the control unit 160 enables the RF unit 110 to access a web
server or a Wireless Application Protocol (WAP) server and sends a
request for weather information and for news information in
connection with the current location to the server in step 1004.
Alternatively, the control unit 160 may request only weather
information or news information.
[0121] Then the control unit 160 receives weather information and
new information in connection with the current location through the
RF unit 110 in step 1005. Alternatively, the control unit 160 may
receive only weather information or news information.
[0122] Next, the control unit 160 determines whether a weather
information display is selected through the input unit 140 in step
1006. If the weather information display is selected, the control
unit 160 enables the display unit 150 to display the received
weather information in step 1007. In a case of receiving only
weather information through the RF unit 110 in the step 1005, the
control unit 160 may omit the step 1006 and perform the step
1007.
[0123] If the weather information display is not selected in the
step 1006, the control unit 160 further determines whether a news
information display is selected through the input unit 140 in step
1008. If the news information display is selected, the control unit
160 classifies the received news information according to regional
levels in step 1009. Regions may have levels such as a country, a
state, a city, a street, etc, and the received news information may
be classified from the highest regional level to the lowest
regional level. In this case, the control unit 160 may enable the
display unit 150 to display such regional levels.
[0124] Next, the control unit 160 determines whether one of such
regional levels is selected through the input unit 140 in step
1010. If one regional level is selected, the control unit 160
enables the display unit 150 to display the received news
information about the selected regional level in step 1011. In a
case of receiving only news information through the RF unit 110 in
the step 1005, the control unit 160 may omit the steps 1006 and
1008 and perform the steps 1009 to 1011.
[0125] In a certain exemplary embodiment, the mobile device 100 may
have a menu item for receiving weather or news information about
other regions. In this case, the control unit 160 may offer a menu
item for entering or selecting a regional name to the display unit
150. If a user enters or selects a desired regional name into or
through the menu item, the control unit 160 enables the RF unit 110
to access a web server or a WAP server and sends the entered or
selected regional name to the server. Then the control unit 160
receives weather or news information about the entered or selected
regional name through the RF unit 110 and enables the display unit
150 to display the received weather or news information. At this
time, the control unit 160 may classify the received weather or
news information according to regional levels and selectively
display it on the display unit 150.
[0126] FIG. 11 is a screen view illustrating an eco-friendly UI
provided by the method in accordance with the fifth exemplary
embodiment of the present invention.
[0127] Referring to FIG. 11, screen view [a] shows an example of a
screen on which weather information about a user's current location
is displayed. As shown, this screen represents a weather condition,
a temperature, an UltraViolet (UV) index, a week weather forecast,
etc. Meanwhile, screen views [b] and [c] show two examples of a
screen on which news information about a user's current location is
displayed. In particular, screen view [b] shows news information
about a relatively lower regional level (i.e., neighborhood),
whereas screen view [c] shows news information about a relatively
higher regional level (i.e., city).
[0128] In a certain exemplary embodiment, the mobile device 100 may
offer information about environmental pollution to a user. In this
case, the control unit 160 receives a GPS signal through the GPS
module and thereby finds current location information about the
mobile device 100. Then the control unit 160 enables the RF unit
110 to access a web server or a WAP server and sends a request for
environmental pollution information about the current location to
the server. Also, the control unit 160 receives environmental
pollution information about the current location through the RF
unit 110 and enables the display unit 150 to display the received
environmental pollution information. Here, the environmental
pollution information may include a local map containing the
current location, environmental pollution states, concentrations of
gases such as O.sub.3, CO.sub.2, and SO.sub.2, or the like.
[0129] Also, the mobile device 100 may have a menu item for
receiving environmental pollution information about other regions.
In this case, the control unit 160 may offer a menu item for
entering or selecting a regional name to the display unit 150. If a
user enters or selects a desired regional name into or through the
menu item, the control unit 160 enables the RF unit 110 to access a
web server or a WAP server and sends the entered or selected
regional name to the server. Then the control unit 160 receives
environmental pollution information about the entered or selected
regional name through the RF unit 110 and enables the display unit
150 to display the received environmental pollution
information.
[0130] FIG. 12 is a screen view illustrating another eco-friendly
UI provided by the method in accordance with the fifth exemplary
embodiment of the present invention.
[0131] Referring to FIG. 12, a screen view shows a name of a
current location (`Quaff Branly St. Paris`) and a map image about
the current location. Also, this screen includes levels of
environmental pollution states such as `good`, `moderate`,
`unhealthy for sensitive`, `unhealthy`, and `very unhealthy` which
are displayed with different colors. In addition, this screen
further represents data about air pollutants such as O.sub.3,
SO.sub.2, CO.sub.2, NO.sub.3, dust, Air Pollution Index (API), etc.
Meanwhile, this screen may further offer a search window for
searching environmental pollution information about other
regions.
[0132] As discussed heretofore, the mobile device 100 according to
the fifth exemplary embodiment of the present invention may offer
weather information, news information, and environmental pollution
information about a user's current location through a suitable
widget. Also, such information may be differently offered according
to regional levels. This exemplary embodiment allows a user to
continuously recognize environmental issues.
[0133] While the present invention has been shown and described
with reference to an exemplary embodiment thereof, it will be
understood by those skilled in the art that various changes in form
and details may be made therein without departing from the spirit
and scope of the invention as defined by the appended claims and
their equivalents.
