Description

  The present invention relates to a portable terminal device, a display control method, and a display control program, and more particularly to a portable terminal device that displays various functions and settings installed in a terminal in a hierarchical structure and selects and executes the menu.

  Recent mobile terminal devices, typified by mobile phones, are not limited to calling functions, but have advanced functions such as camera functions, music player functions, video playback functions, TV reception functions, and electronic payment functions. The number of actions that can be performed has increased significantly.

  When searching for a target function from an enormous variety of functions, it is difficult to display a list of each function and detailed setting items on a screen in a portable terminal device that can be mounted with a relatively small display. In addition, for example, a method in which all items are displayed in a vertical list and searched by scrolling up and down is also inefficient. Therefore, a conventional mobile terminal device generally has a hierarchical menu display in which various functions and settings are divided into a plurality of hierarchies such as major classification, middle classification, and minor classification, and target functions and settings are gradually narrowed down from the major classification. Has been adopted.

  For example, when correcting the time of the clock function of a mobile terminal device, select the “Setting” menu in the menu display of the large classification, then the “clock” menu in the middle classification below, and then the minor classification in the lower classification. The menu display is traced hierarchically, such as selecting the “date / time setting” menu.

  However, for example, as shown in FIG. 7, in the display on a small display, the screen display changes to (A) → (B) → (C) (or (C) → (B) → (A)), and only the menu item at the current hierarchical position is displayed. For this reason, it is difficult to visually grasp the current position in the hierarchical structure such as from which classification the current hierarchy has reached to the lower layer. In the display as described above, for example, when it is desired to redo function selection in the middle, it is difficult to determine how far back the hierarchy should be. Such a situation is becoming more and more serious as the number of functions and setting items of the mobile terminal device increases.

  On the other hand, the hierarchical menu display is generally performed by a television or a DVD (Digital Versatile Disk) player, and a large display is often used. In a large display, for example, as shown in FIG. 8, an upper layer menu is displayed on the left side of the screen, and as the screen moves to a lower layer, the screen display changes as (D) → (E). A display method of displaying the menu on the right side is generally adopted. With such a hierarchical menu display, the current position in the hierarchy (that is, the hierarchy related to the menu item displayed on the rightmost side) can be visually recognized easily.

  Various proposals have been made for portable terminal devices so that the hierarchical menu display can be visually recognized easily. For example, for the upper menu where the lower menu is displayed, the correlation is displayed, or if there are many levels, the upper menu is scrolled out of the screen as necessary, so that the operator can select the desired item. A GUI (Graphical User Interface) to be selected is proposed for a mobile terminal device (see, for example, Patent Document 1 and Patent Document 2). According to the portable terminal devices disclosed in Patent Document 1 and Patent Document 2, the hierarchical structure is devised and displayed on a small screen by displaying an enlarged view of the target portion or displaying the current position in the hierarchical menu. Can do.

  In addition, a mobile terminal device has also been proposed in which an image having a larger number of pixels than the small screen of the mobile terminal device is projected onto the outside of the mobile terminal device by a projector so that a high-quality image can be viewed (for example, (See Patent Document 3). According to the mobile terminal device disclosed in Patent Document 3, an image having a higher resolution than a small screen is projected to the outside, and only the image obtained by thinning out the image data is displayed on the screen of the mobile terminal device. You can check the details of the display.

  Further, between the mobile terminal device with a small display and the display device with a large display, while maintaining the same mutual data, a menu screen (GUI) corresponding to each display screen size is separately formed, There has also been proposed a portable terminal device that displays a screen so that an operator can easily grasp an intended function from the display of an icon or the like (see, for example, Patent Document 4). According to the mobile terminal device disclosed in Patent Literature 4, a display device having a large display and a mobile terminal device having a small display are synchronized, and detailed information that cannot be displayed on the mobile terminal device can be displayed on the display device. .

  However, since the sizes and resolutions of the display screens in Patent Documents 1 and 2 are not different from the conventional ones, compared with the large-screen and high-resolution displays such as the hierarchical display in the above-mentioned television and DVD player, the whole is still The screen display may be difficult to see, such as being unable to look down on the screen.

  In addition, the technique of Patent Document 3 aims to display menus in a hierarchical manner, because the thinned image is reduced and displayed on a small display, and thus the visibility of the display of the mobile terminal device is not improved. It was not a thing.

  Furthermore, in the technique of Patent Document 4, the display device to be connected needs to be a special device that can synchronize information with the mobile terminal device, and the display device and the mobile terminal device share data related to display. I had to leave. Further, the menu is not intended to be displayed hierarchically.

  Hereinafter, a mobile terminal device according to an embodiment of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a block diagram showing a schematic configuration of a mobile terminal device according to an embodiment of the present invention. The mobile terminal device 100 mainly includes a key input device 10, a hierarchical information / setting information storage unit 20, a small screen hierarchical control unit 31, a small screen display control unit 32, a display 40, a key input mode switching device 51, a key input. It includes a converter 52, a key input mode display device 53, a large screen hierarchy control unit 61, a large screen display control unit 62, a communication control unit 70, a projector 80, and the like.

  The key input device 10 performs key input using various button keys or the like provided on the mobile terminal device 100. That is, the key input device 10 receives an input. The hierarchy information / setting information storage unit 20 has functions and settings of the mobile terminal device 100 displayed on a display 40, a projector 80, and a display connected (wireless connection or wired connection) via the communication control unit 70, which will be described later. The setting information related to the item, the hierarchical information related to the hierarchical menu display, and the like are stored. In the hierarchical menu display, various menu items are displayed hierarchically. Note that all the information related to the hierarchical menu display is centrally recorded in the hierarchical information / setting information storage unit 20, whether it is a screen display in the mobile terminal device 100 or an external screen display. In the present embodiment, the menu items include not only setting menu items but also items that can be displayed hierarchically, such as phone book items and scheduler items.

  The small screen hierarchy control unit 31 is a control unit that generates a layout related to a hierarchical menu display to be displayed on the display 40 with reference to the hierarchy information and setting information in the hierarchy information / setting information storage unit 20. The small screen display control unit 32 performs display control related to the hierarchical menu display displayed on the display 40 based on the layout generated by the small screen hierarchy control unit 31.

  The display 40 is a small (small screen) display device such as a liquid crystal display installed in the mobile terminal device 100, and performs menu display related to functions and settings.

  The key input mode switching device 51 determines that the key input from the key input device 10 is a small screen, that is, an input corresponding to the display on the display 40 of the mobile terminal device 100 (first input), or a projector 80 described later. Or a switch or button for selecting or switching the key input mode to determine whether the input corresponds to the display projected on the screen or the display on the large-screen display connected via the communication control unit 70 (second input). is there. That is, the key input mode switching device 51 has a function as an input mode setting unit for setting the key input mode.

  For example, when the small screen input mode as the first input mode is selected, the relationship between the key input and the display operation corresponding to the case where the menu operation of the function or setting is performed while viewing the display on the display 40 is constructed. On the other hand, when the large screen input mode as the second input mode is selected, the relationship between the key input and the display operation corresponding to the menu operation for the function or setting while viewing the projection image of the projector 80 or the screen display of the external display. Is built. A specific display operation will be described later. Note that the switch of the key input mode switching device 51 may be formed in a part of the key input device 10 of the mobile terminal device 100. Hereinafter, the display on the display 40 is also referred to as a small screen display, and the display on the projector 80 or an external display is also referred to as a large screen display.

  The key input converter 52 converts the key input input from the key input device 10 into an input for a small screen as a first input or an input for a large screen as a second input. For example, when hierarchical information or setting information is displayed on a large screen such as the projector 80 in a state where the small screen input mode is selected, the key input is converted into an input for the large screen. On the other hand, when hierarchical information and setting information are displayed on a small screen such as the display 40 in a state where the large screen input mode is selected, the key input is converted into an input for a small screen.

  Even if the key to be pressed is the same, the display operation differs between the case where the input is for small screen operation and the case where the input is for large screen operation. In order to realize this display operation, input conversion is performed as necessary based on a table indicating the correspondence between the type of key pressed and the display operation. This table is shown in FIG. 4 described later, and is stored in the hierarchy information / setting information storage unit 20. Specific operations at the time of key input will be described later.

  The key input mode display device 53 displays the current key input mode selected by the key input mode switching device 51. The key input mode display device 53 may be configured to share the display 40.

  The large-screen hierarchical control unit 61 refers to the hierarchical information and setting information in the hierarchical information / setting information storage unit 20 and relates to the hierarchical display of the menu displayed by the display or projector 80 connected via the communication control unit 70. It is a control part which produces | generates a layout. The large screen display control unit 62 performs display control related to the hierarchical menu display displayed on the external display or the projector 80 based on the layout generated by the large screen hierarchical control unit 61.

  Note that the small screen display control unit 32 and the large screen display control unit 62 both perform control for displaying a cursor. The cursor position displayed on the small screen and the cursor position displayed on the large screen are controlled to have a corresponding positional relationship.

  The communication control unit 70 transmits information related to the layout generated by the hierarchical control unit 61 for large screens and control information of the large screen display control unit 62 related to display of the layouts to an external display device (not shown). To do. On the screen of the external display device to be connected, the same display content as the menu displayed on the display 40 of the mobile terminal device 100 is included, but menu display is performed with a different layout. This makes it easy to grasp the current position in the hierarchical structure.

  The projector 80 is, for example, a small projector that is detachably attached to the portable terminal device 100, and the hierarchical menu display based on the layout generated by the large-screen hierarchical control unit 61 by the display control of the large-screen display control unit 62. I do. On the external wall or screen, the menu is displayed with the same hierarchy as the menu displayed on the display 40 of the mobile terminal device 100, but with a different layout, that is, a display method in which the current position in the hierarchical structure is easy to understand. Is called.

  In the above configuration, the key input device 10 functions as an input unit that receives an input. An external display (not shown) or the projector 80 connected via the communication control unit 70 has a function as a second display device. The large screen hierarchy control unit 61 and the large screen display control unit 62 have a function as a second display control unit that causes the second display device to display menu items of a plurality of layers. The display 40 has a function as a first display device. The small screen hierarchy control unit 31 and the small screen display control unit 32 display the menu items on the first display device, and further select any one of the menu items of the plurality of layers displayed on the second display device. It has a function as a first display control unit for displaying menu items in one layer.

  FIG. 2 is a conceptual diagram for explaining an outline of menu display of the mobile terminal device 100. As shown in FIG. 2, in the mobile terminal device 100, menu display for each layer is performed on the display 40 of the mobile terminal device 100 (small screen display), and at the same time, an external connected to the mobile terminal device 100 The menu can be displayed on the display screen of the projector or the projector 80 in a format that makes it easy to grasp the current position in the hierarchical structure. Moreover, the external display or projector 80 does not need to have special information or display specifications separately. Therefore, a general-purpose display device or projector can be used.

  Further, as will be described later, the operator of the mobile terminal device 100 performs an operation related to selection and setting of a function with the key input device 10 of the mobile terminal device 100 while watching the display on the external display or the projector 80. Can do. The screen display on the external device is also generated based on the same information stored in the hierarchical information / setting information storage unit 20 as the screen display on the display 40. In addition, since update of hierarchy information and setting information is centrally managed by the hierarchy information / setting information storage unit 20, both the small screen display and the large screen display can always be displayed based on the latest values at the same time.

  Next, the operation of the mobile terminal device 100 will be described.

  FIG. 3 is a flowchart showing the procedure of the menu display operation of the mobile terminal device 100. First, when detecting a key input from the key input device 10 (step S10), the key input converter 52 confirms the key input mode of the key input mode switching device 51 (step S11). The key input mode is classified into a small screen operation mode in which the same key input is recognized as a key input corresponding to a small screen display, and a large screen operation mode in which the same key input is recognized as a key input corresponding to a large screen.

  Subsequently, the key input converter 52 converts the detected key input into a key input for small screen operation and a key input for large screen operation according to the selected key input mode (step S12).

  Here, FIG. 4 is a diagram conceptually showing a key input conversion table held by the key input converter 52. The key input conversion table is stored in the hierarchy information / setting information storage unit 20.

  For example, when the large screen operation mode is selected, pressing the “right key” corresponds to a movement operation to a lower layer. As shown in FIG. 4, this operation is equivalent to pressing the “decision key” in the operation on the small screen, that is, the screen of the display 40. In other words, pressing the “right key” in the large screen operation mode is recognized as the “right key” as it is as an input for large screen operation, and is converted to the “decision key” as an input for small screen operation. Is recognized. That is, in the large screen operation mode, the key input converter 52 converts the right key into a determination key that is an example of information as the first input when the display control of the small screen is performed. Therefore, when the “right key” is pressed in the large screen operation mode, the display operation corresponding to the pressing of the “decision key” intended for the same operation can be executed even on the small screen (on the screen of the display 40). .

  On the other hand, even when the small screen operation mode is selected, the input for small screen operation is recognized as it is without input conversion, and the input for large screen operation is recognized after being input converted. For example, pressing the “decision key” in the small screen operation mode is recognized as the “decision key” as it is as the input for the small screen operation, and is converted to the “right key” as the input for the large screen operation. Is recognized. That is, the key input converter 52 converts the determination key into a right key which is an example of information as the second input when the display control of the large screen is performed in the small screen operation mode.

  4 is an example of a key for instructing to move to a lower layer. A clear (CLR) key as an input for small screen operation is an example of a key for instructing movement to an upper layer. The up and down keys as inputs for small screen operation are examples of keys for moving the cursor position. The right key as an input for operating the large screen is an example of a direction key in the same direction as the direction of the lower layer viewed from the upper layer on the large screen. The left key as an input for operating the large screen is an example of a direction key in the same direction as the direction of the upper layer viewed from the lower layer on the large screen. The up / down key as an input for operating the large screen is an example of a direction key in a direction orthogonal to the direction connecting the upper layer side and the lower layer side.

  Subsequently, on the basis of the key input converted into the input for the large screen operation and the input for the small screen operation as necessary by the key input converter 52, the hierarchy control unit 31 for the small screen and the hierarchy for the large screen The control unit 61 refers to the hierarchical information / setting information storage unit 20 (step S13 and step S14), and executes an operation corresponding to each key input (that is, layout generation related to hierarchical menu display) (step S15). And step S16).

  Subsequently, the generated layout information is sent to the small screen display control unit 32 and the large screen display control unit 62. The small screen display control unit 32 is on the display 40, and the large screen display control unit 62 is on the communication control unit 70. Menu display is performed on the external display or the projection surface of the projector 80 connected via the (step S17 and step S18).

  Next, specific display examples of the small screen and the large screen will be described.

  FIG. 5 is a diagram schematically showing a menu display operation when the right arrow key (right key) is pressed in the large screen operation mode. In the example shown in FIG. 5, the right arrow key is a direction key in the same direction as the direction of the lower layer side viewed from the upper layer side on the large screen. As described above, since the pressing of the “right arrow key” is an operation for moving to a lower hierarchy (lower layer), the hierarchy control unit 61 for large screens uses the current display layout (a) to generate hierarchy information / setting information. With reference to the storage unit 20, a display layout (b) including the next lower hierarchy is generated. The large screen display control unit 62 then displays the menu of the display layout (b) on the external large display or projector 80.

  On the other hand, pressing the “right arrow key” is converted into pressing the “decision key” as a key input for small screen operation by the key input converter 52. Accordingly, the small-screen hierarchy control unit 31 refers to the hierarchy information / setting information storage unit 20 based on the current display layout (c) and generates a display layout (d) of the next lower hierarchy. Then, the small screen display control unit 32 displays the menu of the display layout (d) on the display 40.

  In the table shown in FIG. 4, in the small screen operation mode, pressing the “decision key” corresponds to two operations of “move to lower layer” and “select item”. Then, since the position of the cursor in the current display layout (c) is not in the lowest layer of the menu but in the middle of the menu, the small screen layer control unit 31 determines that “move to lower layer”.

  As shown in FIG. 5, in the large screen display, it can be visually seen that the right layer is a lower layer. That is, the current cursor position in the hierarchical structure can be easily grasped. Therefore, it is possible to easily transition to the next higher level or the next lower level. Moreover, the operator can perform a menu operation from the key input device 10 of the mobile terminal device 100 while visually recognizing the large screen display. On the other hand, since the menu operation corresponding to the large screen display is simultaneously reflected in the small screen display, even if the key input mode is changed midway, the operation performed so far can be taken over.

  Similarly, FIG. 6 is a diagram schematically showing a menu display operation when the enter key is pressed in the small screen operation mode. As described above, pressing the “decision key” is two operations, “move to lower hierarchy” and “select item”, but “move to lower hierarchy” from the current display layout (e). Since it is determined that there is, the small-screen hierarchy control unit 31 refers to the hierarchy information / setting information storage unit 20 based on the current display layout (e), and displays the display layout (f) of the next lower hierarchy. Generate. Then, the small screen display control unit 32 displays the menu of the display layout (f) on the display 40.

  On the other hand, pressing of the “decision key” is converted into pressing of the “right arrow key” as a key input for large screen operation by the key input converter 52. Accordingly, the large-screen hierarchy control unit 61 refers to the hierarchy information / setting information storage unit 20 based on the current display layout (g), and generates a display layout (h) including the next lower hierarchy. The large screen display control unit 62 then displays the menu of the display layout (h) on the external display or projector 80.

  As shown in FIG. 6, in the large screen display, it can be visually seen that the layer on the right side is the lower layer. That is, the current cursor position in the hierarchical structure can be easily grasped. Therefore, it is possible to easily transition to the next higher level or the next lower level.

  Further, as shown in FIG. 6, in the mobile terminal device 100, only the hierarchy including the current cursor position is displayed on the small screen, and the large screen can be simultaneously displayed. By using the large screen display, it is possible to easily grasp the current cursor position in the hierarchical structure while performing a menu operation for the small screen display. Therefore, it is possible to easily transition to the next higher level or the next lower level. Since the menu operation corresponding to the small screen display is simultaneously reflected in the large screen display, even if the key input mode is changed in the middle, the operation performed so far can be taken over as it is.

  In the above embodiment, at least the large screen display may be performed, and the setting for omitting the small screen display may be performed.

  Moreover, in said embodiment, in order to switch key input mode, it assumed having the input object changeover switch, a button, etc. as the key input mode switching device 51. FIG.

You may judge. The mobile terminal device 100 may include a viewpoint detection device (not shown), and the key input converter 52 may switch between the small screen operation mode and the large screen operation mode according to the viewpoint detected by the viewpoint detection device.

  That is, the mobile terminal device 100 may include an input unit having a numeric keypad and a direction key instead of the key input device 10. Then, the small screen display control unit 32 (an example of the first display control unit) displays menu items on the display 40 (an example of the first display device) based on the input from the numeric keypad, and displays the large screen. The control unit 62 (an example of a second display control unit) displays a plurality of menu items on the projector 80 or the like (second display device) based on an input from the direction key. According to this configuration, the input target can be easily switched without performing an operation that is necessary for the key input mode switching device 51 (for example, the input target switching button).

  In addition, the mobile terminal device 100 may include an input unit having a numeric keypad and a touchpad instead of the key input device 10. Then, the small screen display control unit 32 (first display control unit) displays menu items on the display 40 (first display device) based on the input from the numeric keypad, and the large screen display control unit 62. The (second display control unit) displays a plurality of menu items on the projector 80 or the like (second display device) based on the input from the touch pad. According to this configuration, the input target can be easily switched without performing an operation like the key input mode switching device 51 (for example, the input target switching button).

  As described above, according to the mobile terminal device 100 in the embodiment of the present invention, in addition to the menu display (small screen display) on the display 40 of the mobile terminal device 100, the structure of the hierarchy is detailed using the large screen display. Therefore, the operator can visually grasp the hierarchical structure of the menu. In addition, the large screen display menu can be directly operated from the key input device 10 of the mobile terminal device 100. Furthermore, since the small screen display and the large screen display are processed in the portable terminal device 100 based on the same hierarchical information / setting information, a special means for simultaneously performing the small screen display and the large screen display is provided. do not need. Therefore, any means (a projector or an external large display) may be used for the large screen display, and the portable terminal device 100 that is excellent in versatility and capable of displaying the large screen can be manufactured at low cost.

  The present invention is useful for a portable terminal device or the like that can easily grasp the entire hierarchical structure without having to perform a synchronization process using a special device.
