[First Embodiment]
Next, a first embodiment of the present invention will be described in detail with reference to the drawings. FIG. 2 is a block diagram showing the configuration of the information processing apparatus according to the first embodiment of the present invention.

  Referring to FIG. 2, an information processing apparatus 10 according to the present embodiment includes a CPU (Central Processing Unit) 11, a ROM (Read-Only Memory) 13, a RAM (Random Access Memory) 14, and a setting. A storage unit 15, a key input unit 16, a display control unit 17, a display unit 18, and a handwriting input device 19 are provided.

  The CPU 11 controls each unit of the information processing apparatus 10 connected via the bus 12. The CPU 11 analyzes and parameterizes the handwritten pattern input from the handwriting input device 19 according to the recognition / control program stored in the ROM 13, and performs a matching process with the handwritten pattern stored in the setting storage unit 15.

  The ROM 13 stores fixed data such as various control programs to be executed by the CPU 11. The RAM 14 stores data temporarily necessary for the CPU 11 to execute the program.

  The setting storage unit 15 stores setting information in which items to be hidden from the user are associated with handwritten patterns to be collated with the contents input from the handwriting input device 19. The setting information will be described later in detail with reference to FIG.

  The key input unit 16 is an input circuit that accepts key inputs from various keys.

  The display control unit 17 is a circuit for driving the display unit 18. The display unit 18 is a display device such as a liquid crystal panel or organic EL (electrofluorescence).

  The handwriting input device 19 is configured by an input device such as a touch panel or a digitizer that acquires coordinates by touching the surface with a stylus pen or a finger. In the present embodiment, the handwriting input device 19 will be described as a touch panel arranged so as to overlap the display unit 18.

  Here, the setting information stored in the setting storage unit 15 will be described. FIG. 3 is a configuration example of setting information stored in the setting storage unit 15. The items in FIG. 3 indicate items specified by the user. In the example of FIG. 3, album A and album B, which are folders storing photo data taken by the user, are designated.

  For example, since the “non-display” column is designated as ON as display control information for album A, album A is not displayed on the item list screen on which album A should be originally displayed. Album B is displayed as usual on the item list screen because the “non-display” column is designated as OFF.

  In the shortcut field of FIG. 3, whether or not to activate a shortcut to albums A and B when a handwritten pattern is input is designated ON or OFF. For example, when the information processing apparatus 10 according to the present embodiment is a mobile phone terminal, when the shortcut function is ON, album A or album B can be opened by inputting a handwritten pattern on the standby screen. It becomes possible.

  In the example of FIG. 3, an example in which folders such as album A and album B are specified has been described. However, for example, function items on a function selection screen (function menu screen) such as an Internet connection function and a camera function, Various setting items of the function may be designated. In this way, it is possible to hide specific function items and function setting items on the function selection screen.

  Further, in addition to the example of FIG. 3, it is possible to define an operation to be executed when a shortcut for each item is activated. For example, when a certain folder is selected, an option to open the folder or start an application program separately designated by the user and read data in the folder may be designated.

  Next, the operation of the present embodiment will be described in detail with reference to the flowcharts of FIGS.

[Handwritten pattern registration processing]
FIG. 4 is a flowchart for explaining the handwritten pattern registration process. The user of the information processing apparatus 10 selects an item to be hidden on an arbitrary item selection screen (step S201), and registers or changes a handwritten pattern to be registered as setting information, or sets various functions of setting information It is selected whether to change (step S202).

  When registration or change of a handwritten pattern is selected (Yes in step S202), the information processing apparatus 10 further determines whether to use an existing (registered) pattern or register a new pattern from the user. The selection is accepted (step S203).

  When a selection to newly register a pattern is made, the information processing apparatus 10 receives an input of a handwritten pattern from the handwriting input device 19 (step S204), analyzes and parameters the input handwritten pattern (step S205). . It is desirable that the operation on the handwriting input device 19 is performed by tracing on the touch panel so that it does not compete with existing processing such as touch. In addition to the methods described in Patent Documents 1 and 2, the parameter derivation algorithm can be freely selected.

  It should be noted that if the parameter obtained in step S205 is very similar to the parameter already registered, it is desirable that the specifications return an error. In that case, you may display the handwritten pattern determined with the said display part 18 being very similar.

  On the other hand, when it is selected in step S203 that an existing (registered) pattern is to be used, the information processing apparatus 10 displays a list of handwritten patterns prepared in advance as templates and templates that the outline user has already registered. To make the user select (step S206).

  As described above, when the input or selection of the handwritten pattern is completed, the information processing apparatus 10 requests and accepts a predetermined pattern confirmation operation from the user (step S207).

  When the pattern determination operation is performed, the information processing apparatus 10 receives from the user the setting of ON / OFF of the non-display function illustrated in FIG. 3 and ON / OFF of the shortcut function (steps S208 and S209).

  Finally, the information processing apparatus 10 stores the input / setting changed contents as setting information (step S210).

[Handwriting pattern input acceptance processing]
FIG. 5 is a flowchart for explaining input acceptance processing for a handwritten pattern registered as described above. When the user inputs a handwritten pattern via the handwriting input device 19, the information processing apparatus 10 reads the input handwritten pattern (step S301), and performs analysis and parameterization as in step S205 of FIG. (Step S302).

  Subsequently, the information processing apparatus 10 collates the parameter generated from the input pattern with the parameter of the handwritten pattern (registered pattern) stored in the setting storage unit 15 (step S303). If the input pattern does not match any handwritten pattern stored in the setting storage unit 15, the information processing apparatus 10 ends the process (step S306).

  On the other hand, when the input pattern matches the handwritten pattern stored in the setting storage unit 15, the information processing apparatus 10 checks whether the shortcut function of the item corresponding to the matching pattern is set to ON. (Step S304).

  As a result of the confirmation, if the shortcut function of the item that matches the input handwritten pattern is not set to ON, the information processing apparatus 10 changes the non-display function column (FIG. 3) of the item from ON to OFF, or Update from OFF to ON (step S305). Thereby, the item corresponding to the handwritten pattern input by the user is switched to display or non-display.

  On the other hand, when the shortcut function of the item that matches the input handwritten pattern is set to ON, the information processing apparatus 10 refers to the link destination column (FIG. 3) of the item and activates the shortcut of the corresponding item. Is performed (step S307). Thereby, the shortcut corresponding to the item corresponding to the handwritten pattern input by the user is activated. For example, when the item corresponding to the handwritten pattern input by the user is a folder, the contents of the corresponding folder are displayed directly from the standby screen or the desktop screen. For example, when the item corresponding to the handwritten pattern input by the user is a specific function item, the program corresponding to the function item is executed, and the function desired by the user can be immediately used.

  As described above, according to the present embodiment, it is possible to control the display state of an arbitrary item by inputting a handwritten pattern.

[Second Embodiment]
Next, a second embodiment of the present invention will be described in detail with reference to the drawings. In this embodiment, instead of displaying / hiding items in the first embodiment described above, the availability of items is controlled using usage control information. Since the configuration and the registration process of the handwritten pattern are the same as those in the first embodiment, the following description will focus on differences from the first embodiment.

  FIG. 6 is a configuration example of setting information stored in the setting storage unit 15 of the information processing apparatus 10 according to the present embodiment. The difference from the setting information of FIG. 3 is that usage control information is set instead of display control information.

  For example, since the “lock” column is OFF for album A, an authentication operation is not required when selecting the item A on the item list screen and browsing its contents. On the other hand, for the album B, since the “lock” column is designated as ON, an authentication operation is required when selecting and browsing the contents on the item list screen. In the present embodiment, the data input at the time of authentication requests handwritten data designated in the handwritten pattern field. In addition, a password or various biometric data may be used.

  FIG. 7 is a flowchart for explaining the handwritten pattern registration process in the present embodiment. The difference from the flowchart of FIG. 4 is that the lock function ON / OFF setting is accepted in step S208a. Other operations are the same as those in the first embodiment described above, and thus the description thereof is omitted.

  As described above, according to the present embodiment, the displayed item is locked instead of being hidden, and thereafter, the use of the item corresponding to the handwritten pattern is locked or unlocked by inputting the handwritten pattern. It becomes possible.

[Third Embodiment]
Next, a third embodiment of the present invention will be described in detail with reference to the drawings. In the present embodiment, a predetermined input mode switching operation is requested before collation processing with a handwritten pattern registered as setting information in the first and second embodiments described above. Since the other configuration and the handwriting pattern registration process are the same as those in the first and second embodiments, the following description will focus on differences from the first and second embodiments.

  FIG. 8 is a flowchart for explaining the handwritten pattern input acceptance process in the present embodiment. The biggest difference from the flowchart of FIG. 5 is that, through steps S401 to S403, it is determined whether or not the input handwritten pattern matches a preset input mode switching pattern. When a mode switching pattern is input, the processing after step S301 corresponding to steps S301 to S307 in FIG. 4 is executed.

  As described above, according to the present embodiment, a simple analysis process is performed in the operation mode waiting for input of the input mode switching pattern, and a more accurate analysis process is performed in the input mode of the handwritten pattern. This analysis process can be divided into a plurality of stages. This makes it possible to deal with complicated pattern input by, for example, determining the speed and rhythm when inputting a pattern, the writing order of a handwritten pattern that is not a single stroke, the finger used during pattern drawing, etc. become.

[Concrete example]
Next, a specific example of screen transition when the configuration of the first embodiment is adopted will be described in detail with reference to FIGS.

  FIG. 9 is a screen transition diagram for explaining the specific operation of the first exemplary embodiment of the present invention. FIG. 9A is a diagram illustrating a state in which the user is displaying a folder list in the camera folder.

  For example, when the folder “Party with friends” is set to OFF as shown in FIG. 10, the determination is made with the cursor placed on the folder “Party with friends” as shown in FIG. When the key is pressed, the captured images stored in the folder can be viewed as shown in FIG.

  On the other hand, when the folder “party with friends” is set to ON as shown in FIG. 11, the folder “party with friends” is hidden as shown in FIG. 9B. When the user inputs a handwritten pattern (gesture) for opening the folder “party with friends” as shown in FIG. 9D, the photographed image stored in the folder is viewed as shown in FIG. 9C. It becomes possible to do.

  In addition, as shown in FIG. 12, when the shortcut function is set to ON, the user can perform handwriting for opening the folder “party with friends” from an arbitrary screen such as a standby screen (see FIG. 9E). When a pattern (gesture) is input, it is possible to browse the captured images stored in the folder as shown in FIG.

  As described above, according to the present embodiment, it is possible to activate a target function in one step by registering a handwritten pattern.

  Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and further modifications, substitutions, and adjustments may be made without departing from the basic technical idea of the present invention. Can be added. For example, the present invention can be generally applied to an information processing apparatus in which a handwritten input device such as a mobile phone terminal, a PDA, a PC (personal computer), various embedded devices, and an in-vehicle terminal can be mounted or connected. At this time, the handwriting input device does not need to be disposed or preferentially connected to the apparatus main body, and for example, a handwritten pattern may be input by a remote controller.

  Further, in the above-described embodiment, it has been described that display / non-display and lock / unlock can be switched by inputting a handwritten pattern. For example, an item that is not displayed is returned to the display state. Depending on the case and the case where the displayed item is not displayed, the requested operation content may be changed. For example, in addition to the input of a handwritten pattern, input of a personal identification number and various biometric data may be requested.

  In the above-described embodiment, the type of item is not limited. For example, the requested operation content may be changed according to the type of item. For example, a handwritten handwritten pattern is used to change the display / non-display of a folder, and the change of display / non-display of a specific function item is more complicated as described in the third embodiment. A simple handwritten pattern may be used.

  In the above-described embodiment, an example of selecting a folder or a function of the information processing apparatus 10 has been described. However, in addition, when receiving selection of an arbitrary item from a large number of item groups having a hierarchical configuration. Can also be applied.

  Further, for example, display / non-display and lock / unlock may be set in a superimposed manner for each item. In this way, when a certain item is used, a two-stage operation such as non-display OFF and unlocking is requested, and it becomes possible to operate more safely.

  In addition, the handwritten pattern is not limited to the handwritten pattern itself exemplified in the above embodiment, and a similar pattern is selected and set from the patterns as shown in FIG. 13 based on the input handwritten pattern. It is good also as what registers with information and performs collation and determination. Further, not only the one-stroke writing pattern shown in FIG. 13 but also a pattern having two or more strokes as shown in FIG. 14 may be used.

  Furthermore, when matching a handwritten pattern with a registered pattern, it is not simply determined whether the shapes match or not. As shown in FIG. 15, the determination may be made based on whether or not the locus (writing order) when the handwritten pattern is input matches.
