In the input window 151b ', a plurality of soft keys 151c' displayed with at least one of letters, symbols, and numbers may be arranged. The soft keys 151c 'may be arranged in the form of a QWERTY key.

When the soft keys 151c 'are touched through the touch pad 135 (see FIG. 2B), characters, numbers, symbols corresponding to the touched soft keys are displayed on the output window 151a'. As described above, the touch input through the touch pad 135 is advantageous in that the soft key 151c 'can not be blocked by the finger when the touch is input, compared with the touch input through the display unit 151. [ In the case where the display unit 151 and the touch pad 135 are formed to be transparent, the fingers located on the rear side of the terminal body can be visually confirmed, thereby enabling a more accurate touch input.

The display unit 151 or the touch pad 135 may be configured to receive a touch input by scrolling, as well as the input method described in the above embodiments. The user can move a cursor or a pointer located on an object displayed on the display unit 151, for example, an icon or the like, by scrolling the display unit 151 or the touch pad 135. [ Further, when the finger is moved on the display portion 151 or the touch pad 135, the path along which the finger moves may be visually displayed on the display portion 151. [ This will be useful for editing the image displayed on the display unit 151. [

One function of the terminal may be executed in response to a case where the display unit 151 (touch screen) and the touch pad 135 are touched together within a predetermined time range. In the case of being touched together, there may be a case where the user clamps the terminal body using the thumb and index finger. The one function may be activation or deactivation of the display unit 151 or the touch pad 135, for example.

The proximity sensor 141 described with reference to Fig. 1 will be described in more detail with reference to Fig.

4 is a conceptual diagram for explaining the proximity depth of the proximity sensor.

As shown in FIG. 4, when a pointer such as a user's finger, a pen, or the like approaches the touch screen, the proximity sensor 141 disposed in or near the touch screen senses the proximity sensor and outputs a proximity signal.

The proximity sensor 141 may be configured to output different proximity signals according to the distance between the proximity-touched pointer and the touch screen (hereinafter referred to as "proximity depth").

In FIG. 4, for example, a cross-section of a touch screen having proximity sensors capable of sensing three proximity depths is illustrated. Of course, proximity sensors that detect less than three or more than four proximity depths are also possible.

Specifically, when the pointer is completely in contact with the touch screen (d0), it is recognized as a contact touch. If the pointer is located on the touch screen at a distance less than the distance d1, it is recognized as a proximity touch of the first proximity depth. If the pointer is located on the touch screen at a distance d1 or less and less than the distance d2, the pointer is recognized as a proximity touch of the second proximity depth. If the pointer is located on the touch screen at a distance d2 or more and less than the distance d3, it is recognized as a proximity touch of the third proximity depth. If the pointer is located at a distance d3 or more on the touch screen, it is recognized that the proximity touch is released.

Accordingly, the controller 180 can recognize the proximity touch as various input signals according to the proximity depth and proximity position of the pointer, and perform various operation control according to the various input signals.

5 is a conceptual diagram for explaining a control method for a touch operation in a form in which a pair of display units 155 and 156 are overlapped.

The terminal shown in this figure is a folder type terminal connected to a main body so that a folder portion is foldable. The first display unit 155 mounted on the folder unit may be of a light transmitting type or a transparent type such as TOLED or the second display unit 156 mounted on the main body may be a form that does not transmit light like an LCD. The first and second display units 155 and 156 may be configured as a touch screen capable of touch input, respectively.

For example, when a touch (a contact touch or a proximity-touch) to the first display unit or the TOLED 155 is detected, the control unit 180 determines whether the touch At least one of the images displayed in the TOLED 155 may be selected or run.

Hereinafter, with respect to the manner in which the information displayed on the other display unit or the LCD 156 is controlled when touching the TOLED 155 exposed to the outside in an overlapped form, a touch, a long touch, a long touch and drag ), And so on.

In the overlapped state (the mobile terminal is in a closed state), the TOLED 155 is arranged to overlap the lower side of the LCD 156. In this state, if a touch such as a long touch (for example, a touch that lasts for 2 seconds to 3 seconds) is detected in a manner different from the touch for controlling the image displayed on the TOLED 155 in advance, ) Causes at least one image of the image list displayed on the LCD 156 to be selected according to the sensed touch input. The result according to the execution of the selected image is displayed on the TOLED 155.

The long touch may also be used to selectively move a desired one of the entities displayed on the LCD 156 to the TOLED 155 (without performing any action thereto). That is, when a user selects one area of the TOLED 155 corresponding to a specific entity of the LCD 156 In the case of a long touch, the control unit 180 moves the corresponding object to the TOLED 155 to be displayed. The entity displayed on the TOLED 155 may also be displayed on the LCD 156 by a predetermined touch input to the TOLED 155, for example, flicking, swirling, and the like. In this figure, the menu No. 2 displayed on the LCD 156 is displayed on the TOLED 155.

If another input, for example, a drag, is detected in addition to the long touch, the control unit 180 is a function related to the image selected by the long touch. For example, a preview screen for the image is displayed on the TOLED 155, As shown in FIG. In this drawing, a case where a preview (male photograph) is performed on the menu No. 2 (image file) is illustrated.

The control unit 180 displays a selection cursor (or a selection bar) of the LCD 156 in the state that the preview screen is being output, while dragging toward another image is further performed on the TOLED 155 while maintaining the long touch And displays the image selected by the selection cursor on a preview screen (female photograph). Thereafter, when the touch (long touch and drag) ends, the controller 180 displays the first image selected by the long touch.

When the slide (the operation of the proximity touch corresponding to the drag) is detected together with the long proximity touch (the proximity touch continuing for at least 2 seconds to 3 seconds) to the TOLED 155 .

When a touch operation other than those described above is detected, the controller 180 can operate in the same manner as a general touch control method.

The control method for the touch operation in the overlapped form can be applied to a terminal having a single display. In addition, the present invention can be applied to a terminal different from a folder type having a dual display.

Hereinafter, embodiments related to a control method that can be implemented in the terminal configured as above will be described with reference to the accompanying drawings. The following embodiments can be used alone or in combination with each other. In addition, the embodiments described below may be used in combination with the above-described user interface (UI).

Hereinafter, a control method of a terminal according to the present invention will be described.

6 is a flowchart of an example of a method of controlling a terminal according to the present invention.

In the present embodiment, it is assumed that a multitasking key (or a concurrent work key) is inputted in an arbitrary operating state. As the multitasking key is input, the terminal may enter a multitasking mode.

The arbitrary operation state may be a standby state in which no menu (or function) is executed, a state in which the menu list is invoked, a state in which an arbitrary menu has already been executed in the menu list .

Also, the multitasking key may be a hardware key attached to one side of a body of the terminal, or may be a software key displayed on the screen. In addition, the multitasking key may be input in the form of a user's command or command without a specific shape. For example, it is possible to instruct multitasking using a user's voice command, proximity touch, gesture, operation such as rotation or shaking of the terminal through the user input unit 130. [

Hereinafter, in the present embodiment, it is assumed that a multitasking key is input using a hardware key or a software key.

When the multitasking key is input as described above (S101), the controller 180 displays a menu (or function) list capable of multitasking on the display module 151 (S102).

The menu list may display at least a menu (or function) capable of multitasking according to a preset option. Alternatively, information indicating whether multitasking is enabled or not can be displayed. A more specific display method of the menu list will be described with reference to other drawings.

As described above, information relating to multitasking can be additionally displayed in the menu list (S103), and the user can select a menu (or a function) to be multitasking by referring to the information displayed additionally.

The user can simultaneously select at least one menu (or function) in the menu list or select one menu at a time (S104). Accordingly, the controller 180 multitask the selected menus (S105).

Hereinafter, a method of controlling a terminal according to the present invention will be described with reference to the accompanying drawings.

FIGS. 7A to 7C are diagrams illustrating menu lists displayed according to a state when a multitasking key is input. FIG.

In particular, FIG. 7A is an exemplary view illustrating a menu list displayed when a multitasking key is input in a standby state in which no menu is executed, and FIG. 7B is a view illustrating a menu list displayed when multitasking FIG. 8 is a view illustrating a menu list displayed when a key is input. FIG. FIG. 7C is an example of a screen for displaying a list of menu items already being executed.

As shown in FIG. 7A, when a multitasking key is input in a standby state, all the multitaskable menu items 310 are displayed, and any menu item 320 set to the default is automatically selected .

For example, it is assumed that the menu items include a telephone related menu, a message related menu, an Internet related menu, a video related menu, a music related menu, and a TV related menu. At this time, if the telephone related menu is set to the default among the menu items, the menu list is displayed with the telephone related menu item selected when the multitasking key is input in the standby state.

Accordingly, when the user inputs a confirmation key (or execution key) in a state in which the default menu item is selected, the default menu item (e.g., telephone related menu item) is immediately executed. You can also use the navigation keys to select other menu items and run them.

Here, the default menu item can be set automatically and can be changed by the user. For example, menu items with the highest frequency of users performing multitasking may be automatically set as default menu items. In addition, the user can directly change the default menu item to another menu item. The automatic selection and manual selection of the default menu items can be set through configuration options (not shown).

Here, the confirmation key for executing the selected menu item, or the navigation keys for selecting a menu item in the menu list may be input in the form of a user's instruction or command. As described above, the key input method (a key input method using a user's instruction or command such as voice without displaying a special key shape) can be applied without any special mention in all embodiments below.

On the other hand, although not shown in the drawings, the menu list may be displayed in one direction such as horizontal or vertical, and may be displayed in a lattice-array format.

In addition, the menu list may be displayed in an overlay manner on an execution screen displayed before the multitasking key is input. The transparency of the execution screen or the menu list may be adjusted for the display of the overlay method. That is, the execution screen can be displayed more transparently and the menu list can be displayed more clearly.

The menu items selected from the menu list may be highlighted and displayed rather than the unselected menu items. For example, a menu item selected from the menu list may be displayed with a size larger than a non-selected menu item. In addition, the menu items selected in the menu list may be displayed in color, and the unselected menu items may be displayed in black and white. In addition, menu items selected from the menu list can be displayed by applying a highlight.

As shown in FIG. 7B, when a multitasking key is input in an operating state in which at least one menu is already being executed, a menu item 330 for displaying all menu items already being executed can be additionally displayed have. For example, it is assumed that the menu items include a telephone related menu, a message related menu, an Internet related menu, a video related menu, a music related menu, a TV related menu, (Menu related to the Internet, music related menu) is already executed, a menu item 330 for displaying the menu items (e.g., the Internet related menu, the music related menu) being executed can be additionally displayed.

When the user selects and executes the menu item 330 that displays the list of menu items already executed as described above, the control unit 180 displays a list 340 of already-executed menu items 340 Can be displayed. For example, if three menus (e.g., an electronic dictionary menu, a timetable menu, an alarm menu) have already been executed, the three menus are displayed.

When at least two or more menus (or functions) are multitasked as described above, the controller 180 displays an indicator indicating the multitasking state and the number of the multitasked menu items in addition to one side of the screen May be displayed.

Information indicating the indicator and the number of multitasking can be simultaneously displayed by one icon 350. At this time, an animation function such as flickering may be applied to the indicator. In addition, when the indicator display area is reduced by the newly displayed icon 350 as described above, the size or shape of the indicator that has been displayed can be automatically changed to a smaller size or shape.

Meanwhile, in the embodiment of the present invention, multitasking can be performed for the same menu (or function). Accordingly, when displaying the list of menu items that have already been executed, the same menu items may be displayed a plurality of times, or the same number of the same menu items being multitasked may be additionally displayed. Embodiments of a display method for multitasking the same menu (or function) will be described later with reference to other drawings.

Hereinafter, a method of displaying the menu list will be described.

In particular, a method of displaying a multitaskable menu list will be described with reference to Figs. 8A to 8D.

As described above, when the multitasking key is input, the control unit 180 displays a multitaskable menu list.

However, among the menu items, there are menu items that can not be executed simultaneously. For example, you can not launch a video-related menu while a music-related menu has already been executed. Or, you can not launch the TV related menu while the video related menu has already been executed. This is because the two menus (or functions) use the same output (eg, sound output module). Alternatively, there may be a menu that can not be mutually multitasked depending on the mechanical or circuit characteristics of the terminal.

When the user executes a second menu item (e.g., a TV related menu) that can not be simultaneously executed while the arbitrary first menu item (e.g., moving image related menu) is being executed as described above, A guidance message indicating that the second menu item (e.g., TV related menu) is not to be executed, or a guidance message asking whether to stop the execution of the first menu item (e.g., a moving image related menu).

Accordingly, the user must cancel the display of the guidance message and then select another second menu item. However, a method of causing the user to select another second menu item after the guide message for the second menu item that can not be simultaneously executed is already output, can be troublesome to the user.

Accordingly, in the present invention, when displaying the menu list, information indicating whether or not multitasking is enabled is displayed together to improve user convenience.

Hereinafter, embodiments of a method of displaying a menu list indicating whether or not the multitasking is possible will be described.

8A is a diagram illustrating a screen for displaying only menu items that can be multitasked in a terminal according to the present invention.

When a multitasking key is input in a state where any same menu is already being executed, the controller 180 can display only the first menu item that is already being executed and the menu items that can be multitasked. For example, when the music-related menu is already executed, if the multitaskable menu is the telephone-related menu 360 and the message-related menu 370, only the two menus can be displayed.

At this time, information on the mutually multitaskable menu items or information on mutually non-multitaskable menu items may be stored in the memory 160 in advance.

The mutually multitaskable menu items may include the same menu (or function). For example, if the message-related menu is a multitaskable menu, the message-related menu item may be displayed in the menu list even though the message-related menu has already been executed.

At this time, the number of times that the same menu can be further multitasked can be set in advance. Accordingly, even if the menu is already executed, the same menu that can be multitaskable can be additionally displayed if the number of times is within the multitaskable number of times.

Further, the message related menu item may further display information (e.g., an indicator) indicating that the same menu is already executed. 8B, when three message related menus have already been executed, the message related menu item 370 includes information 380 indicating that the number of message related menu items already executed is three May be displayed.

FIG. 8C is a diagram illustrating a screen for displaying whether the multitasking is enabled or disabled in the terminal according to the present invention.

When a multitasking key is input as described above, if a menu item (e.g., a music-related menu) is already being executed, the control unit 180 can simultaneously perform (multi-tasking) Menu items (e.g., telephone related menus, message related menus) 390 may be displayed in an active state, and menu items 400 that are not operable with the currently executed menu items may be displayed in an inactive state.

The activation state and the inactive state can be expressed in a transparent or clear state of the menu item. For example, the menu items in the active state can be displayed more clearly and the menu items in the inactive state can be displayed in a relatively more transparent manner.

In addition, the activation state and the inactive state can be represented using the icon shape of the menu item. For example, as shown in FIG. 8D, a menu item in an active state is displayed in a form of a normal icon, and a menu item in an inactive state is displayed in a shape An icon 410 of a type including an image (or text) may be displayed.

Further, a color (for example, red or gray) indicating that the icon can not be used may be additionally applied to the icon.

As described above, since menu items (= menu items that can be multitasked) and menu items that can not be simultaneously operated (= menu items that can not be multitasked) are displayed separately, the user can recognize the menu items that can not be simultaneously operated, There is convenience.

However, even if the menu item is in the deactivated state as described above, selection is not impossible at all. That is, when the user selects a disabled menu item, the control unit 180 stops execution of the previously executed menu item (first menu item), and instead executes the newly selected menu item (second menu item) .

At this time, the control unit 180 may output a guidance message asking whether to stop execution of the first menu item which has been executed before. Accordingly, the user can suspend the execution of the first menu item in response to the inquiry message and execute the second menu item.

In other words, by displaying the non-multitaskable menu items in advance as described above, the user can execute the second menu item only when he or she wishes to execute the second menu item instead of the first menu item.

FIGS. 9A and 9B are views showing display screens of menu items already being executed when the same menu is multitasked. FIG.

As described above, when the multitasking key is input while at least one or more menus are already being executed, a menu item for displaying menu items already executed is additionally displayed in the menu list. When the user selects and executes the further displayed menu item, the control unit 180 displays a list of menu items already being executed. At this time, the number of all the menu items being multitasked is displayed on one side of the screen, and when there are the same menu items being multitasked, the number of the menu items may be displayed.

When the user selects the same menu that is being multitasked, the controller 180 can display the detailed menu list as shown in FIG. 9A. For example, assuming that the same multitasking menu is a memo-related menu and three memo-related menus are already multitasked, three memo-related menu items 420 as a detailed menu list of memo-related items Is displayed.

The detailed menu list may be displayed in a text form or an icon form according to an upper menu list display method.

Alternatively, as shown in FIG. 9B, an execution screen of each submenu item may be displayed in the form of each window. For example, while the memo-related menu is already being executed, the same memo-related menu can be additionally executed. At this time, a separate window 431 - 433 may be generated and the execution screen may be displayed each time the memo related menu is further executed.

Each menu window of the same type that is multitasked as described above can be internally divided using a depth. For example, assuming that the depth of the first created window is 1 (Depth = 1), the depth of the next generated window can be continuously increased to 2 or 3 (Depth = 2, Depth = 3).

Since the depth of each window is information for internally dividing the depth of each window, the depth of each window does not necessarily have to be displayed externally. However, information that can distinguish each window (e.g., the title of the window, the window number, the border color of the window, etc.) can be displayed on one side of the window in consideration of the convenience of the user.

10A and 10B are diagrams for explaining a method of further multitasking the same menu through a separate window.

As shown in FIG. 10A, the same menu 440 already being executed can be additionally selected and executed in the menu list. Each time the same menu 440 is further executed, a new window having a different depth is automatically generated.

Then, the execution screen of the same menu to be executed further can be displayed through the newly created window. At this time, the number of times that the same menu can be further multitasked can be set in advance. That is, the depth of the window in which the same menu can be further multitasked can be set in advance.

Also, as shown in FIG. 10B, a window creation menu (e.g., New) 450 may be provided on one side (e.g., upper side) of each window. Each time the window creation menu is executed, new windows 461 and 462 having different depths can be generated. However, you can not create a new window at the same depth in the same menu. That is, in the same menu, windows having different depths are created.

Then, an execution screen of a newly executed menu (e.g., message 2) can be displayed through the newly created window 452. The window creation menu 450 is automatically created when the same menu is additionally multitaskable. Therefore, if the depth of the multitaskable window is set in advance, the window creation menu 450 is not created in the window created after the depth.

Also, the window creation menu (e.g., New) may be displayed separately.

The separately generated window creation menu may operate with the same function as the multitasking key. For example, when the window creation menu is input, multitaskable menus are displayed, and when one of the menus is executed, a new window is created and the execution screen of the menu can be displayed on the window.

At this time, as shown in FIGS. 10A and 10B, the same menu (or function) numbers 451 and 452 that are multitasked can be displayed on one side of each window.

Hereinafter, a method of selecting one of the above menus when multitasking is performed will be described.

FIGS. 11A and 11B are views illustrating a screen for selecting one of the same multitasking menus.

As described above, if at least one menu has already been executed, a list of the menus that have been executed can be displayed. Then, one of the menus can be selected from the list of menus, and an execution screen of the menu can be displayed.

That is, when the same menus are being multitasked as described above, as shown in FIG. 11A, among the submenus of the same kind already executed in the submenu list 420 of the same type being multitasked One 421 can be selected and the execution screen 422 can be displayed.

Alternatively, when the same menus being multitasked as shown in FIG. 11B are displayed through each of the windows 431 - 433, the touches, the navigation keys, or the above- One can selectively activate one 432.

At this time, the activated window is displayed so as to be displayed in an upper layer of another window which is not activated, and can be displayed more clearly.

Also, although not shown in the drawing, when a menu is additionally executed, a window of a previously executed menu is automatically deactivated and a window of a newly executed menu can be automatically activated.

Further, according to an embodiment of the present invention, the above-described method can be implemented as a code that can be read by a processor on a medium on which the program is recorded. Examples of the medium that can be read by the processor include ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage, etc., and may be implemented in the form of a carrier wave (e.g., transmission over the Internet) .

The mobile terminal described above can be applied to not only the configuration and method of the embodiments described above but also all or some of the embodiments may be selectively combined so that various modifications may be made to the embodiments It is possible.
