     BACKGROUND 
     An embodiment of the present disclosure relates to a method of configuring a watch screen in a wearable electronic device and a wearable electronic device implementing the same. 
     With development of technologies, an electronic device can be manufactured in a form of glasses or a watch which can be worn by a user. Further, the electronic device can be manufactured not only in a modified form but also with the ability to perform various functions. The electronic device, which can be worn by a user, may be named a “wearable electronic device.” The wearable electronic device can perform various functions, and an operation thereof may be controlled by a portable electronic device. When the portable electronic device controls the wearable electronic device, the portable device can be referred to as “a main electronic device”, while the corresponding wearable electronic device can be referred to as a “sub-electronic device.” The wearable electronic device can transmit/receive a signal to/from the portable electronic device (main electronic device), and perform a function corresponding to the received signal. Further, the portable electronic device can transmit a signal received from a server, to the wearable electronic device, to allow the wearable electronic device to receive the signal of the server. 
     Since a wearable electronic device is mostly used while being worn by a user, the size of a screen thereof may be limited. The wearable electronic device may have a screen which is generally smaller than that of a smartphone, and thus may display a limited amount of information. Since the information displayed on the wearable electronic device may be limited, a user may see less information on the wearable electronic device than on another electronic device, such as a smartphone. The foregoing may be inconvenient to the user. 
     The wearable electronic device can change and modify a configuration of a screen in a software scheme in order to display a larger amount of information through the limited size of the screen. Further, the wearable electronic device can be connected to the main electronic device and may generally receive a controlling signal from the main electronic device. In other words, the wearable electronic device does not change or modify information displayed on a display unit of the wearable electronic device or perform functions by itself. The portable electronic device assist the in the execution of an application and/or function by the wearable electronic device by transmitting information corresponding to the application and/or function to the wearable electronic device. Accordingly, since the user of the wearable electronic device can change and request functions, which can be performed by the wearable electronic device, under the control of the portable electronic device, the foregoing can be inconvenient to the user.

       FIG. 1  is a schematic view illustrating communication among a main electronic device, a server, and a wearable electronic device according to various embodiments of the present disclosure. 
     Referring to  FIG. 1 , a wearable electronic device  100  is communicably linked to a portable electronic device  110  and can transmit/receive a signal to/from the portable electronic device  110 . The portable electronic device  110  can share data with the wearable electronic device  100  and control an operation of the wearable electronic device  100 . When the portable electronic device  110  is a main electronic device, the wearable electronic device  100  corresponds to a sub-electronic device, the portable electronic device  110  can control an operation of the wearable electronic  100 . The portable electronic device  110  may change settings of the wearable electronic device  100 . Further, the portable electronic device  110  can perform wireless communication with a server  120  on the basis of an embedded Subscriber Identification Module (SIM) card. The portable electronic device  110  can transmit/receive a signal to/from the server  120 , and can transmit information received from the server  120 , to the wearable electronic device  100 . That is, the wearable electronic device  100  can receive information stored in the server, through the portable electronic device. However, the wearable electronic device according to various embodiments of the present disclosure may have a SIM card autonomously embedded therein and can be communicably linked directly to the server  120  on the basis of the SIM card. For example, when the wearable electronic device  100  is located at a distance at which the wearable electronic device  100  can be communicably linked to the portable electronic device  110 , the wearable electronic device  100  can receive information stored in the server  120 , through the portable electronic device  110 . However, when the wearable electronic device  100  is located at a location at which the wearable electronic device  100  cannot be communicably linked to the portable electronic device  110  or is in a state in which the wearable electronic device  100  cannot be communicably linked to the portable electronic device  110  (e.g. a state in which a battery of the portable electronic device  110  is discharged), the wearable electronic device  100  can be communicably linked directly connected to the server  120  through the embedded SIM card. The wearable electronic device  100  communicably linked to the portable electronic device  110  or the server according to a communication environment, so that a battery thereof can be used more efficiently. The wearable electronic device  100  can consistently save electric power of the battery thereof consumed for connection with the portable electronic device  110  in a state in which the wearable electronic device  100  cannot be connected to the portable electronic device  110 . Thus, the wearable electronic device according to the present disclosure can more efficiently use the battery. 
     Further, the wearable electronic device  100  can receive a phone number different from that of the portable electronic device  110  and autonomously perform communication with the server  120 , on the basis of the embedded SIM card. The wearable electronic device  100  according to various embodiments of the present disclosure performs a communication function through the portable electronic device  110  when the wearable electronic device  100  can be communicably linked to the portable electronic device  110 , and directly performs a communication function through the server  120  when the wearable electronic device  100  cannot be communicably linked to the portable electronic device  110 , so as to more efficiently use the battery. 
     In certain embodiments, the wearable electronic device  100  can display one of one of a plurality of watch screens. Within the watch screens, the wearable electronic device  100  can display at least one icon as a component of the watch screen. The icon(s) can include information from another electronic device, such as the portable electronic device  110 , information originating from the server  120  and provided by the portable electronic device, or information originating from the server  120  and provided directed from the server  120  to the wearable electronic device. 
       FIG. 2  is a block diagram of a wearable electronic device according to various embodiments of the present disclosure. 
     Referring to  FIG. 2 , the wearable electronic device  100  may include a controller  210 , a wireless communication unit  220 , a display unit  230 , an input unit  240 , a memory  250 , and a power source unit  260 . 
     The above-mentioned components can be connected to each other by a bus (not shown), and the controller  210  can transmit a signal (e.g. a control message) to the components (e.g. the wireless communication unit  220 , the display unit  230 , the input unit  240 , the memory  250 , and the power source unit  260 ) to control the components. 
     The controller  210  can generally control an overall operation of the wearable electronic device  100 . For example, the controller  210  can receive a command from the above-mentioned other components (e.g. the wireless communication unit  220 , the display unit  230 , the input unit  240 , the memory  250 , and the power source unit  260 ) to decode the received command so as to perform calculation or data processing according to the decoded command. The controller  210  may include a watch screen configuration module  211 . 
     The watch screen configuration module  211  can configure a watch screen output through the display unit  230  of the wearable electronic device  100 . For example, the watch screen configuration module  211  can configure a watch displayed on the watch screen using an analog watch image or a digital watch image. Further, the watch screen configuration module  211  can determine a type and a location of an icon provided on the watch screen together with the watch. The watch screen configuration module  211  can arrange each of icons on the basis of a shape of a watch screen, which is predetermined by a developer. Further, the watch screen configuration module  211  can automatically arrange an icon associated with a specific icon according to a priority when the specific icon is arranged. For example, when the “health icon” is arranged, the watch screen configuration module  211  can automatically display an icon corresponding to heart rate information associated with the “health icon” at a top priority. Here, the “health icon” may be an icon corresponding to an application for measuring the number of steps which is one of pieces of exercise information for a user. Further, the watch screen configuration module  211  can configure the “weather icon” for determining whether the “health icon” can be consistently performed, to a second priority. An icon associated with a specific icon and a priority of icons may be determined by a developer or user&#39;s setting. 
     Further, when a new application associated with a watch application is installed in a portable electronic device (the portable electronic device  110  in  FIG. 1 ) communicably linked to the wearable electronic device  100 , the watch screen configuration module  211  can compare meta data information of the new application with an information category stored in the memory  250 . Further, the watch screen configuration module  211  can automatically configure a category of a new application and can display an icon on the basis of the configured category. For example, when the new application is an application relating to “weather”, the watch screen configuration module  211  can compare the meta data information with a “weather category” stored in the memory  250 . Further, the watch screen configuration module  211  can configure a category of the new application as the “weather” category. Further, the watch screen configuration module  211  can make a configuration to preferentially display icons configured as the “weather” category when an icon corresponding to the new application is included in the watch screen. The watch screen configuration module  211  can configure a sequence in which icons are displayed according to setting of a developer and a user. 
     The wireless communication unit  220  may include one or more components which enable wireless communication between the wearable electronic device  100  and the portable electronic device  110  or wireless communication between the wearable electronic device  100  and a server (the server  120  in  FIG. 1 ). The wireless communication unit  220  may be communicably linked to the portable electronic device and can perform wireless communication with the portable electronic device. Further, the wireless communication unit  220  can directly perform wireless communication with the server through a SIM card  221 . The SIM card  221  may be inserted into a slot of the wearable electronic device and may be used for wireless communication through the wireless communication unit  220 . The SIM card  221  embedded in the wearable electronic device  100  may be different from a SIM card embedded in the main electronic device, and may provide a phone number different from that of the portable electronic device to the wearable electronic device  100 . That is, when the wearable electronic device  100  cannot be communicably linked to the portable electronic device, the wireless communication unit  220  can receive information from the server while being communicably linked directly to the server. The wireless communication unit  220  can be selectively communicably linked to the portable electronic device or the server under the control of the controller  210 , so that a battery included in the power source unit  260  can be efficiently used. 
     Although not illustrated, the wireless communication unit  220  may include a broadcast reception module, a mobile communication module, a wireless Internet module, a short-range communication module, a location information module, etc. The wireless communication unit  220  can perform wireless communication among the wearable electronic device, the portable electronic device, and the server through the above-mentioned modules.

The display unit  230  may be configured by a touch screen, and may be used as an input device through a touch panel in addition to an output apparatus. The touch panel can recognize a touch input by at least one of a capacitive scheme, a resistive scheme, an infrared scheme, and an ultrasonic scheme. Further, the touch pad may further include a control circuit. In a case of the capacitive scheme, physical contact or proximity recognition is possible. The touch panel may further include a tactile layer. In this case, the touch panel may provide a user with a tactile reaction. In certain embodiments, the display unit  130  can display a watch screen that includes either an analog or digital watch and includes one or more icons as components. 
     The input unit  240  may include a physical input button and the touch panel included in the display unit  230 . The input unit  240  can receive a user&#39;s input to transmit information on the user&#39;s input to the controller  210 . The input unit  240  can recognize a user&#39;s input as a toggle input when receiving the user&#39;s input through the touch panel included in the display unit  120 . Here, the user&#39;s input may include a touch gesture such as a touch, a flick, a swipe, etc. 
     The memory  250  can store a command or data which is received from the controller or other components (e.g. the wireless communication unit  220 , the display unit  230 , the input unit  240 , and the power source unit  260 ) or generated by the controller  210  or the other components. Although not illustrated, the memory  250  may include an internal memory or an external memory.

       FIG. 3  is a flowchart illustrating a method of configuring a screen of a watch according to various embodiments of the present disclosure. 
     Referring to  FIG. 3 , in operation  301 , the controller  210  can configure a watch screen on the basis of at least one application mapped to a watch application. Here, the watch application may be a specific application configuring the watch screen output through the display unit  230  of the wearable electronic device  100 . The watch application may display a watch on the watch screen, and display a watch having an analog form or a watch having a digital form. The controller  210  can variously configure the watch screen using at least one application of applications mapped to the watch application. Here, the various configurations of the watch screen using the at least one application may imply that the watch screen is variously configured using an icon generated in accordance with an application. In the configuration of the watch screen, the whole shape and a location of the icon may be predetermined or configured by a developer in advance. Further, a priority of an application automatically added and displayed when a specific application is selected may be predetermined or determined by a developer in advance. For example, the controller  210  can determine an icon to be included in the watch screen, and can additionally include another icon in the watch screen on the basis of an icon category of the icon. 
     When one icon is the “health icon”, the controller  210  can additionally include the “weather icon” in the watch screen with relation to health on the basis of a health category or an icon for measuring and displaying a heart rate of a user. Since the importance of each icon may be different among different users, the controller  201  can change a priority of icons to be preferentially added on the basis of user&#39;s setting. For example, the controller  210  can change a priority predetermined by a developer on the basis of the user&#39;s setting. 
     Further, in operation  303 , the controller  210  can display a predetermined watch screen in response to the application. For example, the controller  210  can include an icon generated in response to the application in the watch screen and display the watch screen. Although not illustrated, the controller  210  can convert an icon displayed on the watch screen when a user&#39;s input is generated on the icon displayed on the watch screen. For example, the icon displayed on the watch screen can correspond to a toggle key, and may be changed to another icon according to a user&#39;s input. The icon can be changed in an order from a top priority on the basis of a predetermined priority. 
     Various watch screens displayable on the display device will now be described in  FIGS. 4A and 4B . The watch screens can include different categories of icons.  FIGS. 5A and 5B  describe notification icons.  FIGS. 6A to 6D  describe weather icons.  FIGS. 7A and 7B  describe health icons.  FIGS. 8A and 8B  include dual watch icons.  FIGS. 9A and 9B  describe battery icons. 
       FIGS. 4A and 4B  illustrate various examples of watch screens according to various embodiments of the present disclosure. 
     Referring to  FIG. 4A , there are block diagrams of various watch screens  401 ,  402 , and  403 . Watch screen  401  may be displayed on the display unit  230  of the wearable electronic device  100 The controller  210  of the wearable electronic device  100  can display a watch  410  corresponding to a watch application together with variable icons  420  and  430  corresponding to an application mapped to the watch application. That is, the controller  210  of the wearable electronic device  100  can display the watch  410  included in the watch screen together with the variable icons  420  and  430  predetermined by a developer and a user on the display unit  230 . Here, the icons predetermined by a developer and a user are classified into a first icon  420  and a second icon  430 . 
     In watch screen  401 , the controller  210  can change the first icon  420  and the second icon  430  according to a setting. For example, when a watch screen of picture  401  is displayed according to a setting of a developer and a user, the controller  210  can display the first icon  420  as a “health icon” and the second icon  430  as a “notification icon”. The controller  210  can configure the first icon  420  and the second icon  430  individually or configure the first icon  420  and the second icon  430  as icons associated with each other. For example, when the first icon  420  corresponds to a “health icon”, the controller  210  can display the second icon  430  as an icon in which the heart rates associated with the “health icon” is displayed. The controller  210  can configure the second icon  430  by mapping the second icon  430  to an icon corresponding to the first icon  420 . At this time, the second icon  430  mapped to the first icon  420  may be at least one icon. When the number of the second icons  430  mapped to the first icon is two or more, the controller  210  can make a configuration to firstly display an icon having a high priority by configuring a priority between icons disposed in the second icons  430 . Further, the controller  210  can make a configuration to change icons having the next highest priorities other than an icon having the highest priority in accordance with a user&#39;s touch input. Here, the user&#39;s input may include a touch gesture such as a touch, a flick, a swipe, etc. The controller  210  can configure the second icon  430  in accordance with the first icon  420  when the first icon  420  is configured, but the present disclosure is not limited thereto. Further, in watch screen  401 , the controller  210  can also display fixed icons  440  and  450 , which cannot be changed according to a user&#39;s touch input, other than the first icon  420  and the second icon  430  which can be changed according to a user&#39;s touch input. Here, the fixed icons  440  and  450  can be classified into a third icon  440  and a fourth icon  450  for the convenience. In picture  401 , the controller  210  can make a configuration such that weather (for example, “CDY” representing cloudy conditions) is displayed in the third icon  440  and temperature (23 F) is displayed in the fourth icon  450 . The controller  210  can change the third icon  440  and the fourth icon  450  on the basis of setting of a developer and a user. The controller  210  can configure the third icon  440  and the fourth icon  450  by mapping the icons to be associated with each other or configure the third icon  440  and the fourth icon  450  individually. 
     Further, when a specific application associated with the watch application is installed in the portable electronic device (the portable electronic device  110  in  FIG. 1 ) connected to the wearable electronic device  100 , the controller  210  can make a configuration to display an icon generated through the specific application on the wearable electronic device  100 . For example, when a Facebook application is installed in the portable electronic device, the controller  210  can include a Facebook icon generated through the Facebook application in the “notification icon,” e.g.,  430 , in accordance with an icon category. Further, when the “notification icon” is configured, the controller  201  can provide the Facebook icon together with predetermined “notification icons” and configure the corresponding icons according to a user. That is, when a new application associated with the watch application is installed in the portable electronic device connected to the wearable electronic device  100 , the controller  210  can automatically include an icon generated on the basis of the new application in a predetermined icon category in accordance with the corresponding icon category. 
     Watch screen  402  may be a watch screen different from that of watch screen  401  from among various examples of watch screens. In watch screen  402 , the controller  210  can display a variable icons  420 ,  430  and fixed icons  440 ,  450 . The controller  210  can configure icons individually such that the variable icon in picture  402  is identical to the variable icon in picture  401  or can make a configuration to automatically select one variable icon when another variable icon is selected. In watch screen  402 , variable icon  420  can be a battery gauge, while variable icon  430  can be a “notification” icon. 
     Watch screen  403  to  406  may be yet other watch screens from among various watch screens. In picture  403 , the controller  210  of the wearable electronic device  100  can display one variable icon  420  and one fixed icon  440 . In picture  403 , the controller  210  can display the one variable icon  420 , a “notification icon”, and the one fixed icon  440 , such as an icon that displays the temperatures, to provide less but more important information to a user. 
     In watch screen  404 , the controller  210  can display a watch and two variable icons  420 ,  430 . The watch may be configured in an analog scheme or a digital scheme. Further, the two variable icons  420 ,  430  can be configured individually or can be configured by mapping icons associated with each other, which is similar to the above-described contents. The variable icons  420 ,  430  in watch screen  404  may be an arbitrarily illustrated example. 
     In watch screens  405  and  406 , the controller  210  can display a watch and three variable icons  420 ,  430 , and  435 . Watch screens  405  and  406  may be different from each other in that a watch of watch screen  405  is an analog type and a watch of watch screen  406  is a digital type. The three variable icons  420 ,  430 , and  435  displayed in picture  405  and picture  406  may be configured individually or may be configured by mapping them to each other. 
       FIGS. 5A and 5B  illustrate various examples for displaying alarm information on the basis of a watch screen according to various embodiments of the present disclosure. 
     Referring to  FIG. 5A , there are illustrated block diagrams of various “notification icons”  501  . . .  504 . Here, although the wording “NOTIFICATIONS” is displayed in order to identify that the corresponding icon is a “notification icon”, the present disclosure is not limited thereto. Icons  501  and  502  may include a text and a number. The icon  501  has a circular shape and includes the wording “NOTIFICATIONS” displayed at an uppermost end of the interior of a circle and the number of unidentified pieces of notification information displayed at the center of the circle using a number, e.g., “999.” 
     Further, the icon  502  is similar to the icon of picture  501 , but the wording “NOTIFICATIONS” is displayed below the number of unacknowledged notifications, which is displayed using a number, e.g., “999.” The controller  210  can receive the notification information in real-time to update the number of unacknowledged notifications. Although not illustrated, the controller  210  can display the number of unacknowledged notifications by changing a color of the “notification icon”. For example, the controller  210  can display the number of new notifications unacknowledged within the last hour with reference to a current time, using a red number. As a color of the “notification icon” is distinguishably displayed, a user can more efficiently acknowledge the notification information. Further, when there are no unacknowledged notifications, the controller  210  can display the number of unacknowledged pieces of notification information as “0”. 
     Icons  504  may displayed in a state in which notification information cannot be received. For example, a state in which notification information cannot be received may correspond to a state in which the wearable electronic device  100  is far away from the main electronic device (the portable electronic device  110  in  FIG. 1 ) or the main electronic device is powered off. Otherwise, the state may correspond to a state in which a communication environment deteriorates so that the main electronic device cannot communicate with the server (the server  120  in  FIG. 1 ). In an icon of picture  503 , the mark “!” is displayed at a part where the number of unidentified pieces of notification information is displayed using a number in picture  501 . Further, in an icon of picture  504 , the mark “!” is displayed at a part where the number of unacknowledged notifications are displayed using a number in picture  502 .

In the “notification icon” illustrated in  FIG. 5B , a “Notifications image” by which it can be identified that there is at least one piece of notification information and the number of unacknowledged notifications (“999”) are distinguishably displayed. The icons  505  and  506  illustrate a “Notification image” having a circular shape and the number “999” of unacknowledged notifications together while the number “999” of unacknowledged notifications is disposed outside the “Notifications image”. The icon  505  illustrates the number of unacknowledged notifications, at an upper end of the “notification image” using a number, e.g., “999,” and the icon of picture  506  illustrates the number of unacknowledged notifications at a lower end of the “notification image” using a number, e.g., “999.” Here, the “notification image”, which is an image by which it can be identified that there is at least one piece of notification information, can be changed according to setting of a developer and a user. 
     Although not illustrated, the controller  210  may display the “notification icon” by changing the “notification image” or a color of the number of unidentified pieces of notification information. For example, when there is new notification information unidentified within the last one hour with reference to a current time, the controller  210  can change the “notification image” or a color of the number of pieces of notification information. A user can more efficiently identify notification information through the changed “notification icon”. Further, when there is no unidentified notification information, the controller  210  can display the number of unacknowledged notifications as “0”. 
     Icons  507 ,  508  may be icons displayed in a state in which notification information cannot be received. The state in which notification information cannot be received is mentioned above, “No Notifications,” with the description of icons  505  and  506 . In icons  507  and  508 , when notification information cannot be received, the controller  210  can display the wording “No Notification” at a part where the number of unacknowledged notifications are displayed. Here, when notification information cannot be received, the controller  210  illustrates the wording “No Notification”, but the present disclosure is not limited thereto. In icon  509 , when notification information cannot be received, the controller  210  can change and display a “notification image”.

Further, in operation  1007 , the controller  210  can determine whether an editing button is input. Here, the editing button, which is a button generated in the watch screen editing mode, may be a button by which a current screen can be converted into a screen for performing editing in accordance with a watch screen to be edited. In operation  1007 , when the editing button is selected by a user, the controller  210  can change an icon displayed in the watch screen in accordance with a user&#39;s touch input, in operation  1009 . That is, the controller  210  can edit a configuration of the watch screen. The watch screen may include a watch through the watch application, a variable icon  420 ,  430 , and fixed icon(s)  440 ,  450 . Further, the controller  210  can change the variable icon  420 ,  430  and the fixed icon(s)  440 ,  450  in accordance with a user&#39;s touch input. When there are two or more variable icons,  420 ,  430 , the controller  210  can change one variable icon  420  and another variable icon  430  by mapping the one variable icon  420  with the another variable icon  430 . For example, when the one variable icon is a “health icon”  701  to  707 , and  711  to  713 , the controller  210  can make a configuration to display a “weather icon”  801  to  807 ,  811  to  813  by mapping the “weather icon” to the “health icon”. Accordingly, when a user selects one variable icon as the “health icon”  701  to  707 , and  711  to  713 , the controller  210  of the wearable electronic device  100  can automatically change another variable icon to the “weather icon” and display the “weather icon”  801  to  807 ,  811  to  813 . In operation  1007 , when an editing button is not input, the controller  210  can determine whether a watch screen is input not, in operation  1011 . In operation  1011 , when the watch screen  401  to  406  is input, the controller  210  can display the input watch screen, in operation  1013 . The controller  210  can terminate the watch screen editing mode after displaying the watch screen. In operation  1011 , when the watch screen is not input, the controller  210  can directly terminate the watch screen editing mode. 
       FIG. 11  is screen view describing a method of editing a configuration of a watch screen according to various embodiments of the present disclosure. 
     Referring to  FIG. 11 , the controller  210  of the wearable electronic device  100  can display various types of screens (e.g. a watch screen  1110 , a notification screen  1120 , and a widget screen  1130 ) through the display unit  230 . The watch screen  1110 , the notification screen  1120 , and the widget screen  1130  illustrated in  FIG. 11  may be exemplary screens from among screens displayed on the display unit  230  of the wearable electronic device  100 . The controller  210  can detect a touch input pushing a screen, and convert a current screen into each screen (e.g. the watch screen  1110 , the notification screen  1120 , and the widget screen  1130 ) when the touch input is identified. Further, the controller  210  can detect an event by which a current mode is converted into a watch screen editing mode. For example, the controller  210  can convert a current mode into the watch screen editing mode when a touch input  1111  is consistently detected during a predetermined time period. In operation  1101 , the controller  210  can convert a current mode into the watch screen editing mode. Further, the controller  210  can display a screen in the watch screen editing mode through the display unit  230 . In the watch screen editing mode, the controller  210  can display the watch screen  1110  and the notification screen  1120  together. Although not illustrated, a user can select a watch screen to be edited in the watch screen editing mode. In operation  1102 , the controller  210  can detect a user&#39;s touch input corresponding to the watch screen  1110 . Further, in operation  1103 , the controller  210  can display the watch screen  1110 , on which the user&#39;s touch input is detected, using the entirety of the display unit  230 . That is, when a user touches the watch screen  1110 , the controller  210  can convert a current screen from the watch screen editing mode to a general mode again. Meanwhile, in the watch screen editing mode, the controller  210  can detect a user&#39;s touch input input to an editing button. In operation  1104 , the controller  210  can determine that a user&#39;s touch input is generated on the editing button  1150 . Further, in operation  1105 , the controller  210  can edit a configuration of the watch screen  1110 . For example, the controller  210  can display two variable icons  1160  and  1170 , two fixed icons  1161  and  1163 , and an editing completion button  1180  on the display unit  230  to edit the configuration of the watch screen  1110 . Here, the two variable icons  1160  and  1170  can be displayed in a color or a graphical form different from that of the existing watch screen  1110 , in order to indicate that editing can be performed. For example, the two variable icons  1160  and  1170  may be displayed in a red color or a different shadow effect to be distinguished from the surroundings. Otherwise, the two variable icons  1160  and  1170  can be largely enlarged and displayed. Further, the controller  210  can change the two variable icons  1160  and  1170  on the basis of a user&#39;s touch input. Here, the two variable icons  1160  and  1170  can be classified into a first variable icon  1160  and a second variable icon  1170 . Locations of the first variable icon  1160  and the second variable icon  1170  may be exchanged, and is not limited to the drawing. The first variable icon  1160  is changed in response to a user&#39;s toggle input, and a user can configure the second variable icon  1170  to be automatically displayed when the first variable icon  1160  is selected. For example, when a “health icon” is selected as the first variable icon  1160 , the controller  210  can automatically select the “weather icon” as the second variable icon  1170  according to setting of a developer and a user. That is, when the first variable icon  1160  is selected, the controller  210  can select and display the second variable icon  1170  mapped to the first variable icon  1160  according to setting. When there are two or more second variable icons  1170  mapped to the first variable icon  1160 , the controller  210  can firstly display the second variable icon having a high priority on the basis of a predetermined priority. At this time, the second variable icon having a low priority can be changed when a toggle input is generated in the second variable icon  1170 .
