[0003] 2. Description of the Related Art

[0004] Mobile terminals are portable devices, which can provide users with various services such as a voice calling service, a video calling service, an information input/output service, and a data storage service.

[0005] As the types of services provided by mobile terminals diversify, an increasing number of mobile terminals have been equipped with various complicated functions such as capturing photos or moving pictures, playing music files or moving image files, providing game programs, receiving broadcast programs and providing wireless internet services and have thus evolved into multimedia players.

[0006] In order to maximize the portability of mobile terminals, the size of mobile terminals has gradually decreased, whereas the functions of mobile terminals have diversified. Since the size of mobile terminals is small, most display modules for use in mobile terminals generally have a size of about 2-3 inches and are rectangular in shape.

[0007] In order to address the difficulty of providing a variety of functions using an insufficient display region of mobile terminals, widgets have been developed. The term ‘widget,’ as used herein, may include an icon representing a function frequently used, a program for executing the function of an icon selected in response to a key or touch input, and an interface.

[0008] Widgets have been spotlighted as next-generation interfaces for mobile terminals because they can be implemented in mobile terminals and can thus provide a plurality of functions frequently used by a user on a single home screen. Conventionally, however, users are required to manually arrange widget icons on a single home screen displayed on a display module (such as a touch screen), or manually add widget icons to or delete widget icons from the single home screen in accordance with their needs.

[0009] The present invention provides a mobile terminal and a method of controlling the mobile terminal, in which various widgets can be automatically displayed on a home screen in accordance with user-defined time and/or location settings.

For example, if the mobile terminal 100 is in a call mode, the display module 151 may display a user interface (UI) or a graphic user interface (GUI) for making or receiving a call. If the mobile terminal 100 is in a video call mode or an image capturing mode, the display module 151 may display a UI or a GUI for capturing or receiving images.

[0047] If the display module 151 and the user input unit 130 form a layer structure together and are thus implemented as a touch screen, the display module 151 may be used as both an output device and an input device. If the display module 151 is implemented as a touch screen, the display module 151 may also include a touch screen panel and a touch screen panel controller. The touch screen panel may be a transparent panel attached onto the exterior of the mobile terminal 100 and may be connected to an internal bus of the mobile terminal 100. The touch screen panel may keep monitoring whether the touch screen panel is being touched by the user. Once there is touch input detected from the touch screen panel, the touch screen panel may transmit a number of signals corresponding to the detected touch input to the touch screen panel controller. The touch screen panel controller may process the signals transmitted by the touch screen panel, and may transmit the processed signals to the controller 180. Then, the controller 180 may determine whether a touch input has been generated and which part of the touch screen panel has been touched based on the processed signals transmitted by the touch screen panel controller.

[0048] The display module 151 may include at least one of a liquid crystal display (LCD), a thin film transistor (TFT)-LCD, an organic light-emitting diode (OLED), a flexible display, a three-dimensional (3D) display and a transparent display.

The received conditional expression may be used to determine which of the home screen profiles present in the memory 160 should be displayed on the display module 151.

[0093] The received conditional expression may include a time condition, a location condition or a weather condition. For example, if the received conditional expression includes a time condition stating that the ‘at work’ home screen profile should be associated with the hours of 9 a.m. to 6 p.m., a home screen corresponding to the ‘at work’ home screen profile, i.e., the home screen shown in FIG. 4(b), may be displayed on the display module 151 during the hours of 9 a.m. to 6 p.m. every day. If the received conditional expression includes a time condition stating that the ‘after work’ home screen profile should be associated with the hours of 6 p.m. to 9 a.m., a home screen corresponding to the ‘after work’ home screen profile, i.e., the home screen shown in FIG. 4(c), may be displayed on the display module 151 during the hours of 6 p.m. to 9 a.m. every day. If the received conditional expression includes a time condition stating that the ‘on vacation’ home screen profile should be associated with the period between June 1st and June 15th, a home screen corresponding to the ‘on vacation’ home screen profile, i.e., the home screen shown in FIG. 4(a), may be displayed on the touch screen 151 every day during the period between June 1st and June 15th.

[0094] In this regard, the received conditional expression may be interpreted as a condition for activating a certain home screen profile, and may be realized simply by associating a certain period of time or a certain location with the certain home screen profile.

[0095] The received conditional expression may include a location condition. For example, if the user's home is at a first location and the user's office is at a second location, different home profiles may be set for the first and second locations. In this case, the controller 180 may switch home screens displayed on the touch screen 151 according to the location of the mobile terminal 100 (or the user's location). For this, the controller 180 may acquire location information of the mobile terminal 100 from the GPS module 119.

[0096] Thereafter, the controller 180 may determine whether there is a match for the received conditional expression among the home screen profiles present in the memory 160 (S405). Thereafter, if there is a match for the received conditional expression in the memory 160, the controller 180 may load the home screen profile that matches with the received conditional expression from the memory 160 (S406), and may identify a number of widgets registered in the loaded home screen profile, and the display attributes of the widgets (such as the display positions, display types, and display effects of the widgets) (S407). Thereafter, the controller 180 may display the widgets on the touch screen 151 in accordance with widget information included in the loaded home screen profile (S408).

[0097] On the other hand, if none of the home screen profiles present in the memory 160 match with the received conditional expression, the controller 180 may load a default home screen profile from the memory 160 (S409), and may identify a number of widgets registered in the loaded default home screen profile, and the display attributes of the widgets (S410).

[0098] Alternatively, if none of the home screen profiles present in the memory 160 may maintain a home screen currently being displayed on the touch screen 151, instead of displaying a default home screen profile.

[0099] FIG. 6 illustrates a flowchart of a method of controlling a mobile terminal according to a second exemplary embodiment of the present invention. Referring to FIG. 6, the controller 180 may display an ‘edit’ menu for creating a home screen profile on the display module 151 (S501).

[0100] Thereafter, the controller 180 may receive a title input thereto via the ‘edit’ menu, may generate one or more home screen profiles, may register the home screen profiles with the input title, and may store the home profiles in the memory 160 (S502).

[0101] A home screen profiles may include one or more widgets, which are displayed as icons or application windows for executing applications. The user may determine where on the display module 151 the widgets should be displayed by using the ‘edit’ menu. Therefore, the home screen profile may include widget information for identifying the widgets and the display attributes of the widgets (such as the display positions and display effects of the widgets). The display effects of the widgets may include the display positions, transparencies, display types, colors, and sizes of the widgets and other additional information regarding the widgets.

[0102] Thereafter, the controller 180 may assign an attribute value to each of the widgets of each of the home screen profiles present in the memory 160 using the ‘edit’ menu (S503).

[0103] Thereafter, the controller 180 may determine whether there is a key input received from the display module 151 or from the user input unit 130 for selecting one of the home screen profiles present in the memory 160 (S504). If it is determined that one of the home screen profiles present in the memory 160 has been selected using a profile selection menu displayed on the display module 151, the controller 180 may analyze the selected home screen profile and may identify the widgets of the selected home screen profile and the display attributes of the widgets of the selected home screen profile based on the results of the analysis (S505). Thereafter, the controller 180 may display the widgets of the selected home screen profile on the display module 151 in accordance with their display attributes (S506). If it is determined that the selected home screen profile has not yet been selected, the controller 180 may maintain a home screen currently being displayed on the touch screen 151 (S507).

[0104] FIG. 7 illustrates a flowchart of the setting of a conditional expression using an ‘edit’ menu for creating a home screen profile, as performed in the method of the first exemplary embodiment. Referring to FIG. 7, a conditional expression may define a condition for automatically changing home screens upon the arrival of a predetermined time or the arrival at a certain location.

[0105] The controller 180 may determine whether there is a time condition set through the ‘edit’ menu regarding a predetermined home screen profile (S601). A time condition may state that a predetermined home screen must be automatically displayed on the touch screen 151 upon the arrival of a predetermined time. If there is a time condition set regarding a predetermined home screen profile, the controller 180 may apply the time condition to the predetermined home screen profile (S602).

[0106] Thereafter, the controller 180 may determine whether there is a location condition set through the ‘edit’ menu regarding the predetermined home screen profile (S603). A location condition may state that a certain home screen must be automatically displayed on the display module 151 upon the arrival at a certain location, and may be set using a map or text data provided by the ‘edit’ menu.

[0107] If there is a location condition set regarding the predetermined home screen profile, the controller 180 may apply the location condition to the predetermined home screen profile (S604).

[0108] Thereafter, the controller 180 may determine whether the display attributes of a number of widgets of the predetermined home screen profile have been set through the ‘edit’ menu (S605).

[0109] Thereafter, if it is determined that the display attributes of a number of widgets of the predetermined home screen profile have been set, the controller 180 may set the display positions, sizes, display types and transparencies of the widgets based on the display attributes of the widgets (S606), and may store the results of the setting in the predetermined home screen profile (S607).

[0110] FIG. 8 illustrates a diagram of a screen showing an example of an ‘edit’ menu for creating a home screen profile. Referring to FIG. 8, the user may choose a title or category for a home screen profile to be generated from a profile selection menu 240. For example, the user may choose a category ‘at work’ is selected from the profile selection menu 240. A plurality of widgets may be displayed in a widget selection area 220. Each of the widgets may be registered in a home screen profile entitled ‘at work’ by being dragged and dropped into an ‘edit’ window 250.

[0111] FIG. 9 illustrates a diagram of a screen displayed when one of the widgets displayed in the widget selection area 220 shown in FIG. 8 is selected. Referring to FIGS. 8 and 9, if a search widget 225 displayed in the widget selection area 220 is dragged and dropped into the ‘edit’ window 250, the search widget 225 may be displayed in the ‘edit’ window 250 as, for example, a program execution window.

[0112] More specifically, if a touch input for selecting the search widget 225 is received, the controller 180 may display a menu for setting the display attributes of the search widget 225 such as the display position, size and transparency of the search widget 225 on the display module 151. The user may determine the display position of the search widget 225 simply by dragging and dropping the search widget 225.

[0113] The controller 180 may additionally display a popup window for determining the transparency and display type of the search widget 225 on the display module 151. For example, the controller 180 may allow the user to choose the level of transparency between 0 (opaque) and 99 (almost transparent) and thus to determine the transparency of the search widget 225. In addition, the controller 180 may allow the user to choose to display the search widget 225 as an icon or a program execution window.

[0114] When the setting of the display attributes of the search widget 225 is complete, the controller 180 may display a screen shown in FIG. 10 on the display module 151, and may allow the user to additionally edit a home screen profile corresponding to the category ‘at work.’

[0115] FIG. 10 illustrates a diagram of a screen displayed on the display module 151 when the setting of the display attributes of the search widget 225 is complete. Referring to FIG. 10, the widget selection area 220 may be displayed back at the bottom of the display module 151 when the setting of the display attributes of the search widget 225 is complete. A number of widgets displayed in the widget selection area 220 may be added to the ‘edit’ window 250. If one of the widgets displayed in the widget selection area 220, e.g., a traffic information widget 226, is selected, a screen shown in FIG. 11 may be displayed on the display module 151.

[0116] FIG. 11 illustrates a diagram of a screen displayed on the display module 151 when the traffic information widget 226 is selected. Referring to FIG. 11, the controller 180 may display the traffic information widget 226 below the search widget 225, which is a widget selected previously to the traffic information widget 226, may be displayed as a program execution window.

[0117] The traffic information widget 226 may be displayed at a position where it is dragged and dropped. The traffic information widget 226 may display real-time traffic information acquired from a traffic information server (not shown) by the wireless internet module 115 on the display module 151. The display attributes of the traffic information widget 226 may be set using the same method used to set the display attributes of the search widget 225. The user may change the display position of the traffic information widget 226 simply by dragging and dropping the traffic information widget 226, as shown in FIG. 12.

[0118] The present invention can be realized as code that can be read by a processor (such as a mobile station modem (MSM)) included in a mobile terminal and that can be written on a computer-readable recording medium. The computer-readable recording medium may be any type of recording device in which data is stored in a computer-readable manner. Examples of the computer-readable recording medium include a ROM, a RAM, a CD-ROM, a magnetic tape, a floppy disc, an optical data storage, and a carrier wave (e.g., data transmission through the internet). The computer-readable recording medium can be distributed over a plurality of computer systems connected to a network so that computer-readable code is written thereto and executed therefrom in a decentralized manner. Functional programs, code, and code segments needed for realizing the present invention can be easily construed by one of ordinary skill in the art.

[0119] As described above, according to the present invention, it is possible to provide a user with different widget screens in different locations at different times. In addition, there is no need for a user to manually add or delete a widget to or from a home screen in consideration of the circumstances of a mobile terminal providing a single home screen.

[0120] While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention as defined by the following claims.
