Description

  The present invention relates to an information processing apparatus including an input detection unit capable of simultaneously detecting a touched position and a display unit.

  Conventionally, various input methods have been proposed in information processing apparatuses. As an input method performed by the user in the information processing apparatus, a method using key input or a method using a touch panel is known. These input operations are performed not only when entering text such as text, but also when selecting a function, or when authentication is performed by entering a PIN number during entry / exit or settlement. It's being used.

  For example, when a user performs authentication using a key, a method of performing a plurality of key inputs in addition to a method of performing key input one by one has been proposed (for example, see Patent Document 1). Since authentication is performed by operating a plurality of keys, it is possible to increase the security strength compared to inputting keys one by one.

JP 2008-152757 A

  In recent years, various apparatuses have been provided as input devices. Here, as a development of a conventional touch panel, there is a so-called system liquid crystal with a built-in optical sensor.

  Here, the system liquid crystal incorporating the optical sensor will be briefly described with reference to the drawings. First, an outline of the system liquid crystal D80 is shown in FIG. The system liquid crystal D80 realizes a display device function based on a display signal and an input device function based on a read signal. The system liquid crystal D80 is described in an enlarged manner in units of pixels, and is D82, and an optical sensor is built in each pixel (D90), and an operation (touch) from the user can be detected.

  FIG. 20 is a cross-sectional view of one pixel of the system liquid crystal. A protective plate D902, a glass plate D904, a color filter D906, an image sensor D908, a glass plate D910, and a backlight D912 are arranged from the upper surface of the system liquid crystal (the side touched by the user). In the color filter D906, red D906R, green D906G, and blue D906B are arranged as RGB colors, and an image sensor is arranged for each color.

  First, light is emitted from the display backlight D912. The irradiated light is reflected by the subject (user's finger D84) in contact with the display surface (protection plate D902) of the system liquid crystal. The reflected light is subjected to image processing by the image sensor D908. As a result, it is detected that the subject has touched (touched) the display surface (protection plate D902) of the system liquid crystal.

  Since image processing is performed by an image sensor installed for each pixel, it is possible to detect contact positions (coordinates) of a plurality of subjects. That is, a conventional touch panel (for example, a touch panel using a resistive film, a touch panel using a change in capacitance, a touch panel using electromagnetic induction, etc.) has a single location that can be detected as a touched position. The touch panel using the system liquid crystal described above can simultaneously detect a plurality of touched positions.

  Accordingly, when displaying a candidate item (candidate item) such as a displayed image, number, character, symbol, and the like using a touch panel using a system liquid crystal, the user is allowed to select a plurality of items. The usage method is considered.

  In this case, the displayed candidate item is displayed at an arbitrary position in the normal display area (system liquid crystal). However, among the displayed candidate items, there is a problem in that candidate items are not always displayed at positions where the candidate items to be selected by the user can be easily selected.

  For example, consider an authentication system in which a user selects from displayed images and authenticates that the user is a valid user. In this case, the user selects an image to be authenticated by touching. Here, the user selects a plurality of images for authentication, but depending on the display position of the images, there are cases where it is difficult to select (touch). Specifically, when the user touches the next item after touching with the index finger and the ring finger, the desired item is not always displayed within the reach of the remaining finger. Therefore, the user needs to cancel the touched state and select again.

  In addition, when selecting a menu, it cannot be said that a highly convenient system is provided. As an example, there is a system in which when a user selects a menu item in the parent hierarchy, a menu in the child hierarchy is expanded and displayed.

  However, the menu of the child hierarchy is not always displayed on one screen. Therefore, it is necessary to switch the display of the menu of the child hierarchy, but for that purpose, it is necessary to separately perform a scroll operation or the like, and it cannot be said that the information processing apparatus is easy to use.

  In view of the above-described problems, an object of the present invention is to provide an information processing apparatus that is highly convenient for the user by changing the display state of candidate items that are not selected when selecting an item. Is to provide.

In view of the above-described problems, the information processing apparatus of the present invention

While a touch is detected by the input detection unit, an item selection unit (for example, the control unit 100 in FIG. 2; FIG. 5) that selects a selection item from the displayed candidate items based on the touched position. Steps S152 and S154),
When the selection item is selected by the item selection unit for a predetermined time or longer, the candidate item other than the selection item is selected until the next selection item is selected from the candidate items other than the selection item. A display change control unit (for example, the control unit 100 in FIG. 2; steps S156 and S158 in FIG. 5) that performs control to repeatedly change and display the candidate item at a position different from the display position ;
It is characterized by providing.

  The information processing apparatus according to the present invention includes a candidate image storage unit (for example, candidate image DB 142 in FIG. 2) that stores a plurality of images as the candidate items, and a correct image that stores a correct image from the candidate images. And the candidate item display control unit performs control to display a plurality of images stored in the candidate image storage unit (for example, the control of FIG. 2). Unit 100; step S158 in FIG. 5), the item selection unit selects one or a plurality of images from the displayed candidate images (for example, the control unit 100 in FIG. 2; FIG. Step S160 of FIG. 5, if the selected image matches the correct image stored in the correct image storage unit, an authentication unit that authenticates that the user is a valid user (for example, the authentication in FIG. 2). Control unit 110 Characterized by further comprising the step S166, S168) in FIG.

  In the information processing apparatus of the present invention, the authentication unit performs authentication when a touch detected in one selection item among the selection items selected by the item selection unit is released (for example, 2, the control unit 100 in FIG. 2; step S164 in FIG. 5).

The program of the present invention is connected to an input detection unit (for example, the input detection unit 154 in FIG. 2) capable of simultaneously detecting a touched position and a display unit (for example, the display unit 152 in FIG. 2). On the computer,
A candidate item display control function (for example, the control unit 100 in FIG. 2; step S150 in FIG. 5) for performing control for randomly generating and displaying a plurality of candidate items on the display unit;
While a touch is detected by the input detection unit, an item selection function for selecting one or a plurality of selection items from the displayed candidate items based on the touched position (for example, the control unit in FIG. 2) 100; Steps S152 and S154) of FIG.
When the selection item is selected for a predetermined time or more by the item selection function, the candidate item other than the selection item is selected until the next selection item is selected from the candidate items other than the selection item. A display change control function (for example, the control unit 100 in FIG. 2; steps S156 and S158 in FIG. 5) that performs control to repeatedly change and display the candidate item at a position different from the display position of the candidate item ;
It is characterized by realizing.

  According to the information processing apparatus of the present invention, a plurality of candidate items are displayed on the display unit, and based on the detected touch, a selection item is selected from the displayed candidate items and selected for a predetermined time or more. In this case (that is, when a touch is detected for a predetermined time or longer), candidate items other than the selected item are changed and displayed. Accordingly, since items other than the selected item change, it is possible to provide a highly convenient information processing apparatus that can be displayed at a position where it can be easily selected when the item is selected next time.

  In addition, images as a plurality of candidate items are displayed from the images stored in the candidate image storage unit, and one or a plurality of images are selected from the images. And about the image which is not selected, if predetermined time passes, it will change to a different image. If the selected item (image) matches the correct image, it is determined that the user has been authenticated as a valid user. Therefore, when authentication is performed using an image, even if the correct image is displayed at a location that is difficult to press when the user selects a plurality of candidates, the location of the image changes after a predetermined time has elapsed. Will be displayed at a position where it is easy to touch.

  Moreover, authentication will be performed when the touch detected in one selection item is cancelled | released among the selection items selected by the item selection part. Therefore, authentication can be performed only by the user releasing the touch, and a highly convenient information processing apparatus can be provided.

  Embodiments of the present invention will be described below with reference to the accompanying drawings for understanding of the present invention. In addition, the following embodiment is an example which actualized this invention, Comprising: It is not the thing of the character which limits the technical scope of this invention.

Embodiment
[1. First Embodiment]
First, the first embodiment will be described. 1st Embodiment demonstrates the case where this invention is applied about the authentication system which uses an image as an item selected when authenticating that a user is a valid user. That is, first, a candidate image is displayed as a candidate item. Then, the selected image is selected as a selection item from the candidate images. Hereinafter, it explains in detail using a drawing.

[1.1 Device configuration]
First, an overview of the information processing apparatus 1 to which the present invention is applied will be described. In the present embodiment, a case where the present invention is applied to a mobile phone as an example of the information processing apparatus 1 will be described. For example, FIG. 1A shows a case where the display screen of the mobile phone is displayed vertically, and FIG. 1B shows an example where the display screen is displayed horizontally. FIG. 2 shows a functional configuration of the information processing apparatus 1. In the information processing apparatus 1, an authentication control unit 110, a display data control unit 120, a storage unit 140, and a system liquid crystal 150 are connected to the control unit 100 via a bus. A display position control unit 130 is connected to the display data control unit 120.

  The control unit 100 is a functional unit for controlling the operation of the information processing apparatus 1 and includes a control circuit necessary for the information processing apparatus 1 such as a CPU. The control unit 100 implements various processes by reading and executing various programs stored in the storage unit 140.

  The authentication control unit 110 determines whether or not the user is a valid user by determining whether or not an image selected by the user matches an image stored in a correct image DB 144 described later. It is a functional unit for performing authentication control for authentication. The information processing apparatus executes various processes according to the authentication result. For example, when the information processing apparatus 1 is used for entrance / exit control, entry / exit is permitted when authentication is performed correctly. Further, when the information processing apparatus 1 is used in the payment process, the payment process is executed when the authentication is correctly performed.

  The display data control unit 120 is a functional unit that controls data to be displayed on a system liquid crystal 150 (display unit 152), which will be described later, based on an instruction from the control unit 100. The display data control unit displays an image to be displayed on the control unit 100 and displays it at a display position based on the display position control unit 130.

  The display position control unit 130 is a functional unit that determines the display position of an image to be displayed (for example, a candidate image) and controls the display data control unit 120. The content of the display signal output from the display data control unit 120 to the display unit 152 is specifically controlled. Then, the display data control unit 120 outputs to the display unit 152 based on the control signal input from the display position control unit 130.

  The storage unit 140 is a functional unit that stores various data and programs for the information processing apparatus 1 to operate. The control unit 100 implements various functions by reading and executing the program stored in the storage unit 140.

  Here, the storage unit 140 stores a candidate image DB 142, a correct image DB 144, a correct registration program 146, and an authentication program 148.

  As shown in FIG. 3A, the candidate image DB 142 is a DB that stores images (candidate images) to be displayed as candidates to be selected at the time of authentication. In this embodiment, the candidate image is stored in the JPEG format as an example, but it is needless to say that other image formats may be used.

  The correct image DB 144 is a DB in which a correct image for authentication is registered by the user. As shown in FIG. 3B, correct images are registered in the correct image DB 144. This correct image is selected from candidate images stored in the candidate image DB 142.

  The system liquid crystal 150 is a display device that includes a display unit 152 and an input detection unit 154. Although the detailed operation has been described above, the display unit 152 is configured by a liquid crystal display, for example, and displays various types of information based on the display control signal of the display data control unit 120. The input detection unit 154 includes a touch panel that can simultaneously detect a plurality of touch positions, and detects the coordinates of the location touched by the user.

[1.2 Process flow]
Next, the flow of processing in this embodiment will be described. First, correct registration processing for registering a correct image will be described with reference to FIG. Here, the correct answer registration process is a process realized by the control unit 100 reading and executing the correct answer registration program 146 stored in the storage unit 140.

  First, candidate images are read out from the candidate image DB 142 to create and display an image list (step S100). Here, the correct image that is the correct answer is selected by the user (step S102). Note that the number of correct images selected here may be one or more.

  When an image is selected and an operation for registration as a correct image is performed (step S104; Yes), the correct image is registered in the correct image DB 144 (step S106).

  Next, the authentication process will be described with reference to FIG. Here, the authentication process is a process realized by the control unit 100 reading and executing the authentication program 148 stored in the storage unit 140.

  First, the control unit 100 randomly creates a list of candidate images from the candidate image DB 142 and displays the list (step S150). Here, the number of candidate images to be displayed is a predetermined number, a number set by the user, or a number determined in consideration of the display area of the display unit 152. But it ’s okay. In the present embodiment, it is assumed that nine candidate images are displayed.

  When one of the candidate images is selected by the user (step S152; Yes), the selected image is temporarily stored as a selected image (step S154). Here, as a method of selecting a candidate image, the input detection unit 154 detects a touch, and determines which candidate image is selected based on the detected position.

Here, selection of candidate images will be described with reference to FIG. As shown in FIG.
Image A <(x1, y1)-(x2, y2)>
Image B <(x3, y1)-(x4, y2)>
Image C <(x1, y3) − (x2, y4)>
Image D <(x3, y3)-(x4, y4)>
Is displayed.

  For example, it is assumed that two touches of point M and point N are simultaneously detected by the input detection unit 154 and are represented by coordinates M (Xm, Ym) and coordinates N (Xn, Yn), respectively. When the coordinates of the point M are in the position of x1 <Xm <x2, y1 <Ym <y2, the point M is in the area of the image A displayed in the range of (x1, y1)-(x2, y2). Therefore, the item selection unit determines that the image A has been selected. The coordinates of the area corresponding to each display image in this case are stored in the display position control unit 130. Similarly, when the coordinates of the point N are in the positions of x1 <Xn <x2 and y1 <Yn <y2, the point selection unit determines that the image A has been selected because the point N is also in the area of the image A. In this case, two touches of point M and point N have been detected, but the image selected by the item selection unit is only image A (FIG. 6B).

  However, when the coordinates of the point N are in the positions of x3 <Xn <x4 and y3 <Yn <y4, the point N is an area of the image D displayed in the range of (x3, y3)-(x4, y4). Therefore, the control unit 100 determines that the image D is selected. In this case, touches at two points M and N are detected, and images A and D are selected. Thus, even when a plurality of touches are detected simultaneously, only the image A is selected as the former, and a plurality of images A and D are selected as the latter (FIG. 6C).

  Note that if the detected coordinates are out of any image area, the image is not selected. For example, when the coordinates of the point N are in the positions of x2 <Xn <x3 and y3 <Yn <y4, no image is selected by the point N, and only the image selected by the point M becomes the selected image (FIG. 6). (D)).

  Then, the selected image is stored as a selected image. Note that a decorative display indicating that an image has been selected (for example, the selected image is reversed, displayed in a frame, or blinked) may be performed.

  When the selected image is selected, that is, in a state where the candidate image is continuously touched (touch is continuously detected) (step S156; Yes), the selection is performed. A list of candidate images other than images is recreated and displayed again (step S158). In this embodiment, the list is recreated when a predetermined time has passed regardless of the selected selected image. However, when the selected selected image is a specific image set in advance. The list may be recreated, but a process may be added in which the list is not recreated for other images. Conversely, the processing may be such that the list is not recreated when the selected selected image is a specific image set in advance, and the list is recreated when the selected image is another image. Further, in the above description, whether or not to recreate the list is determined using the image as a key, but this may be a selected position instead of the image.

  For example, when nine images are displayed from the candidate images, and one selected image is selected, eight candidate images other than the selected image are read again from the candidate image DB 142, and a list display is performed. Recreate and display.

  Note that the currently displayed candidate image and the redisplayed candidate image may be different images, or such a restriction may not be provided. In addition, a restriction may be provided so that the same image is not displayed at the same position during redisplay. With respect to these display methods, it is possible to increase the security strength by increasing the restrictions, and it is possible to improve convenience by reducing the restrictions.

  Subsequently, it is determined whether or not the next image is selected from the next candidate images (step S160). When the next image is selected (step S160; Yes), the next selected image is also stored as a selected image (step S162).

  Here, it is determined whether image authentication has been executed by the user (step S164). If the user performs an operation for performing image authentication, the process proceeds to step S166 (step S164; Yes → step S166). If an operation for performing image authentication is not performed, the process starts from step S156. Are repeatedly executed (step S164; No-> step S156).

  Here, various methods are conceivable as operations for performing image authentication. For example, it is determined that the selection state of the selected image has been released as a trigger for performing image authentication (that is, whether or not the input detection unit 154 continues to be touched (when touching with a user's finger) For example, whether or not there is a distant finger), or when the authentication button is selected by the user as a trigger for performing image authentication.

  When performing image authentication, it is determined whether or not the currently selected image matches the correct image registered in the correct image DB 144 (step S166). Here, if the selected image matches the correct image, it is determined that the authentication is successful (step S166; Yes → step S168). On the other hand, if the selected image does not match the correct image, it is determined that the authentication has failed (step S166; No → step S170).

  As a trigger for the operation for performing image authentication in step S164, for example, when the selected image and the correct image match, authentication may be automatically performed. The operation flow in this case is shown in FIG.

  That is, without executing step S164, it is determined in step S166 whether the currently selected image matches the correct image. If the selected image matches the correct image, it is determined that the authentication is successful (step S166; Yes → step S168). If the selected image does not match, the process is repeatedly executed from step S156. As a result, the user can execute the authentication process without being aware of the operation “execute authentication”.

[1.3 Example of operation]
Subsequently, an operation example of the present embodiment will be described. FIG. 8 is a diagram for explaining an example of the display screen W100 displayed on the system liquid crystal 150. FIG.

  On the display screen W100, nine candidate images are read from the candidate image DB 142 and displayed in a list (step S150 in FIG. 5). If the correct image used for authentication is not displayed, the user selects one arbitrary image (step S152; Yes → step S154). In this figure, the image M100 is selected (touched) by the user F100 as the selected image. In this case, the image M100 is touched with the user's index finger.

  When a predetermined time elapses in the state of FIG. 8 (step S156; Yes), candidate images other than the selected image M100 are updated and displayed (step S158). FIG. 9 is an example of a display screen W102 when a candidate image other than the image M100 is updated and displayed. Here, the user F102 further selects an image M102 that is a correct image (step S160; Yes → step S162). Here, the image M100 is selected with the user's index finger, and the image M102 is selected with the user's ring finger.

  When a predetermined time elapses in the state of FIG. 9, candidate images other than the selected image M100 and image M102 are updated and displayed (step S158). FIG. 10 is an example of a display screen W104 when an image other than the image M100 and the image M102 is updated and displayed. Here, an image M104 that is a correct image is displayed on the display screen W104. Here, the user tries to select the image M104. However, since it is difficult to select the image at the current display position, the user waits until a predetermined time elapses.

  When a predetermined time elapses in the state of FIG. 10, candidate images other than the selected image M100 and image M102 are updated and displayed (step S156; Yes → step S156). FIG. 11 is an example of a display screen W106 when candidate images other than the images M100 and M102 are updated and displayed. On the display screen W106, the image M104 is displayed at a location that can be easily selected by the user F106. Therefore, the user F106 further selects an image M106 that is a correct image (step S160; Yes → step S162). Here, the image M100 is selected by the user's index finger, the image M102 is selected by the user's ring finger, and the image M104 is selected by the user's middle finger.

  Since all the correct images have been selected in the state of FIG. 11, the user cancels the selected state of the image M100 that is not the correct image (step S164; Yes). FIG. 12 is a diagram illustrating an example of the display screen W108 when the selection state of the image M100 in FIG. 11 is cancelled.

  Since the selected state of the image is released, the authentication control unit 110 collates the currently selected image with the correct image DB 144 (step S166). If the selected image matches the correct image, it is determined that the authentication has been successful (step S166; Yes → step S168).

  As described above, according to the present embodiment, when a user selects a plurality of images (items), the display position and contents of an image other than the selected image change every time a predetermined time elapses. It will be. As a result, when the user selects an image (item), the user can select an image naturally without pressing it, and a highly convenient authentication system can be realized.

  In addition, about embodiment mentioned above, although the example using an image as a candidate item was demonstrated, for example, by displaying other items, such as a number, a character, a figure, a symbol, a photograph, and a color, and selecting from the item concerned Of course, authentication may be performed.

  In the above-described embodiment, the list of candidate images is re-created at a timing when a predetermined time has elapsed. However, the images may be changed at other timings. For example, in step S160, a list of candidate images other than the selected image may be re-created at the timing when the next image is selected, and the user can arbitrarily instruct to re-create the list of candidate images. You may give by timing.

  In the above-described embodiment, when recreating a list of candidate images, it has been described as being read from the candidate image DB 142 and displayed. However, for example, the types of images once displayed as a list of candidate images are left as they are. The position may be changed. In this case, since the displayed image does not change, an effect that the user can select fewer steps can be expected.

  Further, in addition to the above-described embodiment, for example, when a predetermined time has elapsed with respect to the position of the image and the image to be displayed, a new candidate image is read from the candidate image DB 142 and a list of candidate images is displayed. And when an image is selected, you may perform control of moving only the position of the displayed candidate image. As described above, various methods for displaying a list of candidate images are conceivable.

  In addition, about embodiment mentioned above, although the example which authenticates by canceling | releases a selection image was demonstrated, for example, an authentication button is displayed on the same display part as another image, and authentication is performed by selecting it. It is also good. Further, the authentication button may be arranged on the front surface, side surface, back surface, etc. of the terminal instead of being displayed on the display unit, and authentication may be performed by pressing the button. In particular, when it is arranged on the side surface / back surface, it is difficult for a third party to visually recognize that the selection screen and the authentication button are pressed simultaneously.

  Moreover, although the example of authentication was demonstrated in embodiment mentioned above, you may use for selection of a menu, input of a number etc., for example. That is, the scope of application of the present invention is that an information processing apparatus capable of detecting a plurality of touched positions at the same time, when an item displayed on the information processing apparatus is being pressed, Any object whose display is updated may be used.

[2. Second Embodiment]
Next, the second embodiment will be described. In the second embodiment, a case where a menu item is selected as an item selected by the user will be described as an example. That is, first, the menu item of the first hierarchy is displayed as the item of the parent hierarchy. Then, according to the selected first hierarchy, menu items of the second hierarchy that are child hierarchy items are displayed. Hereinafter, it explains in detail using a drawing.

[2.1 Device configuration]
FIG. 13 shows the configuration of the information processing apparatus 2 to which the present invention is applied. The information processing apparatus 2 includes a control unit 100, a menu control unit 210, a display data control unit 120, a display position control unit 130, a storage unit 240, and a system liquid crystal 150 (the display unit 152 and the input detection unit 154). It is configured with. In addition, the same code | symbol is attached | subjected about the same component demonstrated in 1st Embodiment, and the description is abbreviate | omitted.

  The menu control unit 210 is a control unit that controls switching of menus to be displayed, update instructions, and the like. Control is performed to read out necessary menu items from a menu list 242 to be described later and display a menu screen.

  The storage unit 240 is a functional unit that stores various data and programs for the information processing apparatus 2 to operate. The control unit 100 implements various functions by reading and executing the program stored in the storage unit 240. Here, the storage unit 240 stores a menu list 242 and a menu display program 244.

  The menu list 242 is a list that stores menu items (for example, “Web”) in the information processing apparatus 2 in association with item numbers (for example, “A”). Here, “A”, “B”, “C”, “D”, and the like indicate menus in the first layer (parent layer). In addition, menus of the second hierarchy (child hierarchy) corresponding to the first hierarchy (parent hierarchy) are also stored. For example, “B-1” is a menu of a child hierarchy having “B” as a parent hierarchy.

[2.2 Process flow]
Subsequently, a menu display process which is a process in the second embodiment will be described with reference to FIG. The menu display process is a process realized by the control unit 100 reading and executing the menu display program 244 stored in the storage unit 240.

  First, the display data control unit 120 displays the first layer menu (step S200). Then, a menu item is selected from the displayed first hierarchy (step S202).

  When the menu item is selected by the user (step S202; Yes), a lower menu (second layer) of the selected menu item is displayed (step S204). Here, when the selection of the menu item of the first layer is canceled, the process is executed again from Step S200, and the menu display of the first layer is returned (Step S206; Yes → Step S200).

  When a predetermined time has passed without the menu item of the second layer being selected in the state where the menu of the second layer is displayed (Step S206; No → Step S208; No → Step S210; Yes), The display of the menu item in the second hierarchy is updated (step S212).

  On the other hand, when the menu item of the second hierarchy is selected in the state where the menu of the second hierarchy is displayed, the selected function is executed (Step S206; No → Step S208; Yes → Step S214).

[2.3 Example of operation]
Subsequently, an operation example in the second embodiment will be described with reference to the drawings.

  FIG. 16 is a diagram showing an example of a display screen W200 that displays the first hierarchy (parent hierarchy). On the display screen W200, a menu item K200 in the first hierarchy is displayed (step S200 in FIG. 15). Here, the user F200 touches the menu item K202 “B Mail” to select it (step S202; Yes). As a method of touching by the user F200, for example, the user F200 may touch with a hand (finger) or may touch with a stylus.

  In the state of FIG. 16, the screen that is transitioned when the menu item K202 is selected is the display screen W210 of FIG. On display screen W210, menu item K210 in the first layer (parent layer) is selected by user F210. Here, in the first hierarchy (parent hierarchy), the menu item K212 that is not selected is displayed lightly.

  In the center of the screen, a menu item K214 in the second hierarchy (child hierarchy) associated with the selected menu item K212 is displayed (step S204). Here, the menu of the second layer corresponding to the menu item K210 “B Mail” has 12 menu items with reference to the menu list 242 shown in FIG. However, only seven menu items can be displayed on the display screen W210. Accordingly, the menu items having the item numbers “B-1” to “B-7” are displayed on the W210, and the menu items “B-8” to “B-12” are not displayed.

  In the state of FIG. 17, the screen that transitions when the selection state of the menu item K210 has elapsed for a predetermined time is the display screen W220 of FIG. Since the predetermined time has elapsed, the menu control unit 210 updates the menu display of the second hierarchy (step S210; Yes → step S212). That is, “B-12” not displayed on the display screen W210 is displayed, and “B-7” is not displayed instead.

  As described above, the display of the menu item K220 in the second hierarchy is updated and displayed every time a predetermined time elapses while the menu item K210 remains selected.

  Various methods can be considered as a method for updating the display of the menu. For example, when the selected state has elapsed on the display screen W210 of FIG. 17, the menu items “B-8” to “B-12” that are not displayed may be switched and displayed. Further, by displaying “B-1” and “B-2” in succession from “B-8” to “B-12”, the menu items in the second layer may be displayed in succession. good.

  Further, the menu control unit 210 may provide a visual effect when switching and displaying the second layer menu display. For example, when switching the display of the menu item of the second hierarchy, the user can perform an intuitive operation by providing an effect of rotating the menu item K210 of the first hierarchy.

  In the present embodiment, the menu list is stored and the menu display is performed based on the menu list. However, the present invention is not limited to the method described above. That is, it may be described as a menu selection process directly in the program (process).

  Further, for convenience of explanation, the menu hierarchy has been described as two levels, a first hierarchy (parent hierarchy) and a second hierarchy (child hierarchy), but it is needless to say that three or more hierarchies may be used.

  As described above, according to the present embodiment, even when all the menu items cannot be displayed on the display screen, the display of the menu items can be switched depending on the state of the user's touch. Therefore, the user can display the menu with a simpler operation, and can easily select the desired menu.

  That is, for example, the candidate item display control unit in the information processing apparatus performs control to display, as candidate items, items in the parent hierarchy among the items in the hierarchical structure (for example, the control unit 100 in FIG. 13; step S200 in FIG. 15). ), In the item selection unit, based on the touch detected by the input detection unit, the parent hierarchy item selection unit (for example, the control unit 100 in FIG. 13; step S202 in FIG. 15) selects the item in the displayed parent hierarchy. ), And a child hierarchy display control unit (for example, the control unit 100 in FIG. 13; step S204 in FIG. 15) that performs control to display items of child hierarchies that can be selected from the parent hierarchy selected by the parent hierarchy item selection unit. ), And as the display change control unit, when the item selection unit has been selected for a predetermined time or more, control to change and display the item of the child hierarchy Uco hierarchical display change controller (e.g., controller 100 in FIG. 13; step S210, S212 of FIG. 15) may include.

  Further, in the child hierarchy display change control unit in the information processing apparatus, control is performed so that the items of the child hierarchy not displayed on the display unit are displayed (for example, the control unit 100 in FIG. 13; step S212 in FIG. 15). It can also be.

  Accordingly, the parent hierarchy item is displayed on the display unit, and the parent hierarchy item is selected based on the touch, and the child hierarchy item is displayed according to the selected parent hierarchy. When the selection is made for a predetermined time or longer (that is, when a touch is detected for a predetermined time or more), the display of the child hierarchy item is changed. Accordingly, by selecting the parent hierarchy by touch, the display of the child hierarchy items is changed, and it is possible to provide a highly convenient information processing apparatus.

  In addition, when changing the display of the child hierarchy items, it is possible to perform control so that the child hierarchy items that are not displayed on the display unit are displayed.
