  The header database 7 stores information regarding the list 21. In the first embodiment, information on artists included in a playlist for music playback is stored.

  The display unit 8 displays information processed by the screen display processing unit 5. Specifically, the characters recognized by the handwritten character recognition unit 3, the slide bar 20, the list 21, the selection button 22, and the like are displayed. That is, the display unit 8 displays the index sequence and the list under the processing (control) of the slide bar / list display processing unit 42 (index sequence / list display control unit). Moreover, it has the function to receive the input by a user's touch.

  Next, the operation of the information processing apparatus 1 will be described.

  FIG. 3 is a flowchart illustrating an example of the operation of the information processing apparatus 1.

  In step S <b> 101, the input coordinate acquisition unit 2 determines whether coordinate information on the screen when the user touches the screen of the display unit 8 has been acquired. If it is determined that the coordinate information has been acquired, the process proceeds to step S102. On the other hand, if it is determined that the coordinate information has not been acquired, the process of step S101 is repeated until the coordinate information is acquired.

  In step S102, the control unit 4 determines whether or not the time until the coordinate information is acquired is within the base point determination timer.

  Here, the base point determination timer is the time until the coordinate information is acquired again after the input coordinate acquisition unit 2 acquires the coordinate information in step S101 (the time until the user touches again after releasing the finger from the screen). , And is used to determine whether or not to display the slide bar 20 on the display unit 8 with the point indicated by the user touching the screen as a base point. The base point determination timer is set in step S107 and step S118 described later.

  If it is determined that it is not within the base point determination timer, the process proceeds to step S103. On the other hand, if it is determined that it is within the base point determination timer, the process proceeds to step S113.

  In the first step S102 after the operation of the information processing apparatus 1 is started, the base point determination timer is not set. Therefore, it is determined that it is not within the base point determination timer, and the process proceeds to step S103.

  In step S103, the control unit 4 cancels the setting of the base point determination timer.

  In step S <b> 104, the handwritten character recognizing unit 3 performs a process of recognizing a character handwritten by the user via the screen of the display unit 8 based on the coordinate information acquired by the input coordinate acquiring unit 2.

  Specifically, the handwritten character recognition unit 3 performs character recognition processing by combining newly acquired coordinate information with already stored coordinate information. Here, the already stored coordinate information refers to the coordinate information stored in step S109. The newly acquired coordinate information refers to the latest coordinate information acquired in step S101.

  In step S105, the handwritten character recognition unit 3 determines whether or not the handwritten character input by the user has been recognized. If it is determined that the handwritten character is not recognized, the process proceeds to step S106. On the other hand, if it is determined that the handwritten character is recognized, the process proceeds to step S111.

  In step S106, the handwritten character recognizing unit 3 determines whether or not a time limit is set for the time for performing the handwritten character recognition process. Here, the time limit refers to a threshold of time for the handwritten character recognition unit 3 to perform handwritten character recognition processing in step S105.

  If it is determined that the time limit is not set, the process proceeds to step S107. On the other hand, if it is determined that the time limit is set, the process proceeds to step S108.

  In step S107, the handwritten character recognition unit 3 sets the time limit and stores the coordinate information acquired in step S101.

  In step S108, the handwritten character recognition unit 3 determines whether or not the time required for the handwritten character recognition process is within the time limit. If it is determined that the time is within the time limit, the process proceeds to step S109. On the other hand, if it is determined that it is not within the time limit, the process proceeds to step S110.

  In step S109, the handwritten character recognition unit 3 stores the coordinate information acquired in step S101.

  In step S110, the handwritten character recognition unit 3 deletes the stored coordinate information and cancels the time limit setting.

  If it is determined in step S105 that the handwritten character has been recognized, in step S111, the display information storage processing unit 43 stores the character recognized by the handwritten character recognition unit 3 in the display information storage unit 6. I do. That is, the character recognized by the handwritten character recognition unit 3 is stored in the display information storage unit 6.

  In step S112, the control unit 4 sets a base point determination timer.

  If it is determined in step S102 that the time is within the base point determination timer, in step S113, the control unit 4 cancels the setting of the base point determination timer.

  In step S114, the slide bar / list creation processing unit 41 acquires the characters stored in step S111 or step S118 from the display information storage unit 6. In the first step S114 after starting the operation of the information processing apparatus 1, the character stored in step S111 is acquired from the display information storage unit 6.

  In step S <b> 115, the slide bar / list creation processing unit 41 creates the slide bar 20 and the list 21 based on the characters acquired from the display information storage unit 6.

  Specifically, the slide bar list creation processing unit 41 creates the slide bar 20 including the characters acquired from the display information storage unit 6, and the artist list 21 using the characters acquired from the display information storage unit 6 as initials 21. Is obtained from the heading database 7 and created.

  In step S <b> 116, the slide bar / list display processing unit 42 performs processing to display the slide bar 20 on the display unit 8 based on the indication point where the user touches the screen. That is, the slide bar / list display processing unit 42 (index string / list display control unit) instructs the display unit 8 based on information recognized by the handwritten character recognition unit 3 (input information recognition unit). Control is performed so that the index string is displayed in one direction with the designated point as a base point. In addition, processing is performed so that a list 21 of at least one artist corresponding to a portion specified by the user in the slide bar 20 (using the character selected by the user as an initial) is displayed on the display unit 8.

  Next, the screen display processing unit 5 performs processing for displaying the slide bar 20 and the list 21 processed by the slide bar / list display processing unit 42 on the display unit 8. That is, the slide bar 20 and the list 21 are displayed on the display unit 8.

  In step S117, the enlargement processing unit 44 enlarges and displays the character selected by the user on the slide bar 20 displayed on the display unit 8. Specifically, the character selected by the user is enlarged and displayed as the selection button 22.

  In step S <b> 118, the display information storage processing unit 43 performs a process for storing the character selected by the user on the slide bar 20 in the display information storage unit 6. That is, the character selected by the user on the slide bar 20 is stored in the display information storage unit 6.

  In step S119, the control unit 4 determines whether or not the user has stopped touching the screen.

  When the user interrupts the touch on the screen, the process proceeds to step S120. In this case, for example, it is determined that the user has lifted his / her finger or the like from the screen, or the position touched by the user has moved outward from the screen edge.

  On the other hand, when the user has not interrupted the touch on the screen, the process proceeds to step S121. In this case, it is determined that the user is performing an operation (scroll operation) for sliding the slide bar 20 to display another list 21. Here, the term “slide” refers to an operation of moving while the user touches the screen (without interrupting the touch).

  In step S120, the control unit 4 sets a base point determination timer.

  In step S <b> 121, the input coordinate acquisition unit 2 acquires coordinate information on the screen when the user touches the screen of the display unit 8.

  By performing the above operation, the user can select a specific artist from the playlist for music reproduction.

  In particular, when the user interrupts the designation of the slide bar 20 (index column) displayed on the display unit 8 in step S119, the display information storage unit 6 (storage unit) displays the information of the location designated immediately before the interruption. Remember. Next, the slide bar / list display processing unit 42, when the designation is resumed within a predetermined time after the user interrupts the designation, in one direction based on the indication point designated again by the user, Control is performed so that the slide bar 20 including the location stored in the display information storage unit 6 is displayed on the display unit 8.

  Next, user operations corresponding to the operations shown in FIG. 3 will be described with reference to FIGS.

  First, basic user operations will be described with reference to FIGS.

  First, as shown in FIG. 4, the user manually inputs an initial letter of a specific artist name in an arbitrary area on the screen of the display unit 8.

  Next, as shown in FIG. 5, the user touches an arbitrary location on the screen of the display unit 8 within a predetermined time (within the base point determination timer).

  As a result, as shown in FIG. 6, the slide bar 20 including the characters input by handwriting is displayed on the display unit 8 in one direction based on the indication point touched by the user. In the first embodiment, the base point is an instruction point touched by the user, and the one direction is a vertical direction including the base point. At this time, characters input by handwriting are enlarged and displayed as selection buttons 22 at the instruction points touched by the user.

  In addition, a list 21 of artists whose initial characters are handwritten characters is displayed. That is, a list 21 of at least one artist corresponding to a portion (character) designated by the user in the slide bar 20 is displayed.

  Next, as shown in FIG. 7, when the user slides on the slide bar 20, the character selected by the user on the slide bar 20 is enlarged and displayed as the selection button 22 in accordance with the slide. At the same time, according to the slide, an artist list 21 with the character selected by the user as an initial is displayed.

  Next, an operation in which the user temporarily stops touching the screen and then touches the screen again will be described with reference to FIGS. As described above, as described above, a case where the user releases a finger or the like from the screen, or a case where the position touched by the user is likely to come out from the edge of the screen can be considered.

  FIG. 8 shows a case where the user slides on the slide bar 20 and reaches the screen end of the display unit 8.

  Next, as shown in FIG. 9, the user lifts his / her finger from the screen (interrupts touching the screen). At this time, the character (here, “g” shown in FIG. 8) selected immediately before the user lifts his / her finger from the screen is stored in the display information storage unit 6.

  Next, as shown in FIG. 10, the user touches an arbitrary location on the screen within a predetermined time (within the base point determination timer).

  As a result, as shown in FIG. 11, the slide bar 20 including the character selected immediately before the user lifts his / her finger from the screen stored in the display information storage unit 6 is based on the indication point touched by the user. Is displayed on the display unit 8. At this time, at the indication point touched by the user, the character selected immediately before the user releases the finger from the screen is enlarged and displayed as the selection button 22.

  From the above, according to the first embodiment, the user can select a specific artist from a playlist for music reproduction. That is, it is possible to improve the operability when searching for an arbitrary list and specifying one piece of information. Specifically, even a small screen such as a car navigation device or a smartphone can be reliably and easily operated without the user feeling stressed. In particular, since the slide bar can be displayed at an arbitrary position by the user without being displayed at the fixed position, an operation for specifying the position of the slide bar by the user's vision becomes unnecessary, and the operation time is shortened. This is particularly effective when a quick operation by the user is required, such as a car navigation device.

  In addition, the characters selected by the user are enlarged and displayed, thereby facilitating character recognition.

  In the above description, the slide bar as the letter picker and the list corresponding to the slide bar have been described. However, the present invention is not limited to the letter picker.

  For example, as shown in FIG. 12, a pagination can be used as the slide bar 23.

  Specifically, after the user inputs a number (here, “13”) by hand, and touches an arbitrary place on the screen, the slide bar 23 is displayed in one direction with the touch position as a base point. In the first embodiment, the base point is an instruction point touched by the user, and the one direction is the left-right direction including the base point. At this time, the number input by handwriting is enlarged and displayed as the selection button 25 at the indication point touched by the user.

  In addition, pages corresponding to numbers input by handwriting are displayed as a list 24. That is, the page (list 24) corresponding to the location (number) designated by the user in the slide bar 23 is displayed.

  When the user slides on the slide bar 23, the number selected by the user on the slide bar 23 is enlarged and displayed as the selection button 22 in accordance with the slide. At the same time, a page corresponding to the number selected by the user is displayed according to the slide. In the first embodiment, a page that is one selection element is displayed as a list 24.

  From the above, even if the letter picker in the first embodiment is replaced with pagination, the same effect as in the first embodiment can be obtained. That is, the number input by the user is information that serves as a clue for selection when selecting one page from an aggregate of a plurality of pages (selection elements).

<Embodiment 2>
First, the configuration of the information processing apparatus according to the second embodiment of the present invention will be described.

  The second embodiment is characterized by voice input instead of the handwriting input in the first embodiment.

  In the second embodiment, a case where a specific artist is selected from a playlist for music playback will be described as an example.

  FIG. 13 is a diagram illustrating an example of the configuration of the information processing apparatus 1 according to the second embodiment.

  As illustrated in FIG. 13, the information processing apparatus 1 includes an input voice acquisition unit 9 and a voice recognition unit 10, and the input voice acquisition unit 9 is connected to a microphone 11.

  In step S205, the control unit 4 sets a base point determination timer.

  In step S206, the input coordinate acquisition unit 2 determines whether or not coordinate information on the screen when the user touches the screen of the display unit 8 has been acquired. If it is determined that the coordinate information has been acquired, the process proceeds to step S207. On the other hand, if it is determined that the coordinate information has not been acquired, the process of step S206 is repeated until the coordinate information is acquired.

  In step S207, the control unit 4 determines whether it is within the base point determination timer.

  Here, the base point determination timer is the time until the input coordinate acquisition unit 2 acquires the coordinate information in step S206 after the voice recognition unit 10 recognizes the voice in step S204, or the input coordinate acquisition unit 2 in step S206. Indicates the threshold value of the time until the coordinate information is acquired again after acquiring the coordinate information (the time until the user touches again after releasing the finger from the screen). This is used to determine whether or not to display the slide bar 20 on the display unit 8. The base point determination timer is set in step S205 and step S216 (described later).

  When it is determined that it is not within the base point determination timer, the process proceeds to step S209. On the other hand, if it is determined that it is within the base point determination timer, the process proceeds to step S208.

  In step S208, the control unit 4 cancels the setting of the base point determination timer.

  In step S209, the control unit 4 cancels the setting of the base point determination timer.

  In step S210, the slide bar / list creation processing unit 41 acquires the characters stored in step S204 or step S214 from the display information storage unit 6. In the first step S210 after the operation of the information processing apparatus 1 is started, the character stored in step S204 is acquired from the display information storage unit 6.

  In step S211, the slide bar / list creation processing unit 41 creates the slide bar 20 and the list 21 based on the characters acquired from the display information storage unit 6.

  Specifically, the slide bar list creation processing unit 41 creates the slide bar 20 including the characters acquired from the display information storage unit 6, and the artist list 21 using the characters acquired from the display information storage unit 6 as initials 21. Is obtained from the header database 7 (see FIG. 2).

  In step S <b> 212, the slide bar / list display processing unit 42 performs processing to display the slide bar 20 on the display unit 8 based on the indication point where the user touches the screen. In addition, processing is performed so that a list 21 of at least one artist corresponding to a portion specified by the user in the slide bar 20 (using the character selected by the user as an initial) is displayed on the display unit 8.

  Next, the screen display processing unit 5 performs processing for displaying the slide bar 20 and the list 21 processed by the slide bar / list display processing unit 42 on the display unit 8. That is, the slide bar 20 and the list 21 are displayed on the display unit 8.

  In step S <b> 213, the enlargement processing unit 44 enlarges and displays the character selected by the user on the slide bar 20 displayed on the display unit 8. Specifically, the character selected by the user is enlarged and displayed as the selection button 22.

  In step S <b> 214, the display information storage processing unit 43 performs processing for storing the character selected by the user on the slide bar 20 in the display information storage unit 6. That is, the character selected by the user on the slide bar 20 is stored in the display information storage unit 6.

  In step S215, the control unit 4 determines whether the user has interrupted touching the screen.
