  Next, a flow of a series of processes according to the present embodiment will be described using the flowchart shown in FIG. Each step of FIG. 3 to be described later is an operation executed by the CPU 101 of the information processing apparatus 100.

  First, in step S301, using the storage unit 201, the form application 210 installed in the information processing apparatus 100 is read from the flash memory 114, loaded into the RAM 103, and the form application is activated.

  In step S <b> 302, the storage unit 201 is used to accept selection of form data to be displayed by the started form application 210, the form data selected by the user is acquired from the flash memory 114, and is read into the form application 210. At this time, the form data to be read is the latest form data. Among the form data managed by the form data management table 600 in FIG. 6, the record having the form data name 602 selected by the user is specified. And the form data of the record with the newest creation date 603 among the specified records is read. In the present embodiment, the form data is version-managed by generation (version), and form data of past generations can also be displayed. Basically, in order to display the latest form data, in step S302, the latest form data is read by the processing described above.

  The form data management table 600 (see FIG. 6) includes a form ID 601, form data name 602, and creation date 603. The form ID 601 is identification information assigned uniquely for each form. A form data name 602 indicates the name of the form data. The creation date 603 indicates the date on which the form data was created. In the present embodiment, the created date is managed, but it may be an updated date. You may hold both. It should be noted that the items constituting the form data management table 600 may exist in addition to this as necessary.

  In step S <b> 303, the form data browsing screen 400 is displayed on the touch panel 110 using the display unit 202, and the form data read in step S <b> 302 is displayed in the form data display area 401 of the form data browsing screen 400.

  FIG. 4 is a diagram showing an example of the screen configuration of the form data browsing screen 400. The form data browsing screen 400 includes a form data display area 401. The form data read in step S302 is displayed in the form data display area 401. When a flick operation is accepted from the user in the form data display area 401, the pages constituting the form data are scrolled and other pages are displayed in the form data display area 401. In the present embodiment, description will be made assuming that scrolling is performed vertically, but other pages may be displayed by scrolling horizontally. Further, the form data browsing screen 400 includes various buttons. In particular, in this embodiment, an annotation button (stamp) 402, an annotation button (memo) 403, a generation change button 404, a setting button 405, and an end button 406 are provided. The operation when the pressing of each button is detected will be described later.

  In step S304, the touch operation detection unit 203 is used to determine whether a touch operation on the touch panel 110 has been detected. If it is determined that a touch operation has been detected, the process proceeds to step S305. If it is determined that the touch operation has not been detected, the process of step S304 is repeated, and the process waits until the touch operation is detected.

  In step S305, it is determined whether or not the setting button 405 has been pressed by the touch operation detected in step S304. When a tap operation is performed in an area where the setting button 405 of the touch panel 110 is displayed, it is determined that the setting button 405 has been pressed. If it is determined that the setting button 405 has been pressed, the process proceeds to step S306. If it is determined that the setting button 405 has not been pressed, the process proceeds to step S307.

  In step S306, the setting screen 500 is displayed on the touch panel 110 using the display unit 202, and the operation setting of the form application 210 is accepted.

  FIG. 5 is a diagram illustrating an example of the screen configuration of the setting screen 500. The setting screen 500 includes an annotation option selection field 501, a scroll mode selection field 502, and a deceleration mode option selection field 503. The annotation option selection field 501 includes a check box for selecting whether or not to display an annotation attached to a generation different from the generation of the form data being displayed in the form data display area 401. As described above, the form data is version-managed by generation (version), and basically the latest generation is displayed, but the past generation form data can also be displayed. Therefore, it is possible to select whether or not to display the annotation added to the other generation of form data with the check box in the currently displayed generation of form data.

  The scroll mode selection field 502 includes radio buttons for selecting what kind of scrolling should be performed when a flick operation is performed on the displayed form data page. When the normal mode is selected, scrolling is performed at a speed according to an instruction from the user regardless of whether the annotation is displayed. When the deceleration mode is selected, when the annotation is displayed, scrolling is performed at a speed slower than the speed according to the instruction from the user, and after the annotation passes, the speed is returned to the speed according to the instruction from the user.

  The deceleration mode option selection field 503 has a check box for selecting whether to decelerate when a stamp annotation is displayed, and a check box for selecting whether to decelerate when another generation annotation is displayed. With. Stamp annotations add secrets and seals to form data, and are often not annotations to be confirmed by the user. Therefore, it is possible to select whether to decelerate even when a stamp annotation is displayed by a check box. In addition, since annotations of a generation different from the currently displayed generation may not be related to the form data of the currently displayed generation, it is possible to select whether to slow down even when this is displayed. Yes.

  These check boxes and radio buttons can be switched ON / OFF by a tap operation from the user. When the user performs a tap operation on the setting button 504, the information processing apparatus 100 detects pressing of the setting button 504, and registers information selected by each check box / radio button in the setting table 610 in FIG.

  The setting table 610 (see FIG. 6) includes an annotation option 611, a scroll mode 612, a deceleration mode option A613, and a deceleration mode option B614. The annotation option 611 stores information selected in the annotation option selection field 501. When the annotation attached to another generation is not displayed in the form data display area 401 (when the check box is OFF), “0” is stored, and the annotation attached to another generation is stored in the form data display area 401. When displayed (when the check box is ON), “1” is stored.

  In the scroll mode 612, information selected in the scroll mode selection field 502 is stored. “0” is stored when the normal mode is selected, and “1” is stored when the deceleration mode is selected.

  The deceleration mode option A613 stores a selection status of a check box for selecting whether to decelerate when a stamp annotation is displayed, which is included in the deceleration mode option selection field 503. Even if a stamp annotation is displayed, “0” is stored if the speed does not decelerate (check box is OFF), and “1” is stored if the speed is decelerated when the stamp annotation is displayed (check box is ON). .

  The deceleration mode option B 614 stores a selection status of a check box for selecting whether to decelerate when an annotation of another generation included in the deceleration mode option selection field 503 is displayed. Even if another generation of annotation is displayed, “0” is stored if it does not decelerate (check box is OFF), and “1” if it is decelerated (check box is ON) when another generation of annotation is displayed. Is stored.

  In this manner, the operation setting of the form application 210 is accepted in step S306, and the operation setting is registered in the setting table 610. When registration is completed, the process returns to step S304.

  Returning to the description of FIG. In step S307, it is determined whether the annotation button (stamp) 402 or the annotation button (memo) 403 is pressed by the touch operation detected in step S304. When the tap operation is performed in the area where the annotation button (stamp) 402 or the annotation button (memo) 403 of the touch panel 110 is displayed, it is determined that the annotation button (stamp) 402 or the annotation button (memo) 403 is pressed. To do. If it is determined that the annotation button (stamp) 402 or the annotation button (memo) 403 is pressed, the process proceeds to step S308. If it is determined that the annotation button (stamp) 402 or the annotation button (memo) 403 has not been pressed, the process proceeds to step S309.

  In step S308, a process of adding an annotation to the page of form data displayed in the form data display area 401 is executed. Details of the annotation assignment process are shown in FIG. When the annotation assignment process is completed, the process returns to step S304.

  In step S309, it is determined whether or not the generation change button 404 has been pressed by the touch operation detected in step S304. When the tap operation is performed in the area where the generation change button 404 of the touch panel 110 is displayed, it is determined that the generation change button 404 is pressed. If it is determined that the generation change button 404 has been pressed, the process proceeds to step S310. If it is determined that the generation change button 404 has not been pressed, the process proceeds to step S311.

  In step S310, in response to pressing of the generation change button 404, a generation selection field 701 (see FIG. 7) is displayed on the touch panel 110 in the form data browsing screen 400, and selection of a generation to be displayed in the form data display area 401 is accepted. When the user performs a tap operation on the generation to be displayed, the information processing apparatus 100 detects this, reads the form data of the tapped generation, and displays it in the form data display area 401. A case where form data of one generation past is selected is shown in a form data browsing screen 400 at the bottom of FIG. It can be seen that the upper right version of the form data display area 401 is outdated. In this way, it is possible to switch to a different generation. It is also possible to add annotations to the generation form data displayed in step S310. When the process of step S310 is completed, the process returns to step S304.

  In step S311, it is determined whether or not an instruction to scroll the page of form data has been given by the touch operation detected in step S304. When the flick operation is performed in the vertical direction in the form data display area 401 of the touch panel 110, it is determined that the scroll of the form data page is instructed. If it is determined that scrolling of the form data page is instructed, the process proceeds to step S312. If it is determined that scrolling of the page of form data is not instructed, the process proceeds to step S313.

  In step S312, a process of scrolling the page of form data displayed in the form data display area 401 is executed. Details of the scroll processing are shown in FIG. When the scroll process is completed, the process returns to step S304.

  In step S313, it is determined whether or not the end button 406 has been pressed by the touch operation detected in step S304. When the tap operation is performed in the area where the end button 406 of the touch panel 110 is displayed, it is determined that the end button 406 is pressed. If it is determined that the end button 406 has been pressed, the process proceeds to step S314. If it is determined that the end button 406 has not been pressed, the process returns to step S304.

  In step S314, the form data displayed in the form data display area 401 is closed, and the form application started in step S301 is ended. The above is the flow of a series of processes in the present embodiment.

  Next, details of the annotation assignment process will be described with reference to the flowchart of FIG. Each step in FIG. 8 described later is an operation executed by the CPU 101 of the information processing apparatus 100.

  In step S 801, the position (coordinates) to which the annotation is added is specified using the annotation adding unit 211. When a tap operation on the page displayed in the form data display area 401 is detected after detecting the pressing of the annotation button (stamp) 402 or the annotation button (memo) 403, the coordinates in the page corresponding to the tapped position are detected. Is set as a position to which an annotation is added.

  In step S802, the annotation assignment unit 211 is used to identify the type (attribute) of the annotation to be assigned. As described above, there are two types of annotations, stamp and memo, in this embodiment. The type of annotation can be specified depending on which one of the annotation button (stamp) 402 or the annotation button (memo) 403 is pressed.

  In step S803, using the storage unit 201, the annotation table 620 is updated using the information specified in steps S801 and S802. An example of the table configuration of the annotation table 620 is shown in FIG.

  The annotation table 620 includes an annotation ID 621, a form ID 622, a page number 623, an arrangement position 624, a type 625, a character string 626, and a creation date 627. The annotation ID 621 stores unique identification information for each annotation that is issued each time an annotation is added. The form ID 622 stores the form ID 601 of the form data with the annotation. The page number 623 stores the page number of the form data with an annotation. The arrangement position 624 stores coordinates (upper left coordinates, lower right coordinates) with annotations. The type 625 stores the type of attached annotation. The character string 626 stores a character string input when the annotation type 625 is a memo. The creation date and time 627 stores the date and time for which the annotation is given. In the present embodiment, the creation date / time is used, but the update date / time may be used.

  In step S <b> 804, using the display unit 202, the annotation added to the form data page is displayed in the form data display area 401.

  In step S805, it is determined whether or not the type of annotation assigned is “memo”. If the record type 625 added in step S803 is “memo”, it is determined that the assigned annotation type is “memo”. If it is determined that the assigned annotation type is “memo”, the process proceeds to step S806. If it is determined that the type of annotation provided is not “memo”, that is, “stamp”, the annotation addition processing is terminated and the processing is returned to the caller.

  In step S806, an input of a character string for the annotation of the attached memo is accepted. By displaying a software keyboard on the touch panel 110 and accepting a tap operation from the user, a character string to be displayed in the annotation of the memo is acquired.

  In step S807, the character string acquired in step S806 is stored in the character string 626 of the record added in step S803. In step S808, the character string stored in character string 626 in step S807 is displayed in the annotation of the attached memo.

  FIG. 9 shows an example when annotation is added to the form data page. In FIG. 9, the form data whose form ID 601 is “REP003” is displayed on the form data browsing screen 400. The upper form data browsing screen 400 displays the second page, and the lower form data browsing screen 400 displays the third page. As shown in the annotation table 620 of FIG. 6, a memo annotation is assigned to the second page of the form data. This is displayed in the form as shown at 901. On the other hand, a stamp annotation is given to the third page of the form data. This is displayed in the form as shown at 902. Further, when the past generation of the third page of the form data is given a memo annotation, and the setting screen 500 is set to display the annotation given to another generation (annotation option 611 is set). In the case of “1”), this annotation is displayed. This is displayed in a form as shown in 903. The annotations of other generations are displayed so as to be distinguishable from the annotations of the currently displayed generation. For example, as shown in FIG. 9, the annotation is made translucent, and the date and time (creation date and time 627) at which the annotation was added is also displayed. In this way, annotation is added and displayed.

  Next, details of the scroll processing will be described with reference to the flowchart shown in FIG. Each step in FIG. 10 described later is an operation executed by the CPU 101 of the information processing apparatus 100.

  In step S1001, the scroll speed calculation unit 212 is used to specify the scroll speed of each page of the form data displayed in the form data display area 401 in accordance with the flick operation detected in step S304. The scroll speed specified here is the speed immediately after scrolling. Since the method for calculating the scroll speed uses the prior art, the description thereof is omitted. Basically, if the speed of the flick operation is high, the scroll speed is also increased accordingly.

  In step S <b> 1002, the scroll control instruction unit 213 is used to obtain a deceleration when each page of the form data displayed in the form data display area 401 is scrolled. The scroll in the present invention is inertial scroll. Therefore, once scrolling is performed, scrolling does not stop unless the user performs a touch operation. Therefore, in step S1002, the deceleration is acquired, and using this, the scroll is gradually decelerated, and finally the scroll is stopped. The deceleration may be stored in advance in the storage unit 201 or may be calculated using a conventional technique.

  In step S1003, it is determined whether or not the scroll mode 612 of the setting table 610 is “0”. That is, it is determined whether or not the normal mode is selected in the scroll mode selection field 502 of the setting screen 500. If it is determined that the scroll mode 612 is “0”, the process proceeds to step S1004. If it is determined that the scroll mode 612 is not “0”, that is, the scroll mode 612 is “1”, the process proceeds to step S1006.

  In step S1004, each page of the form data is scrolled using the scroll speed and deceleration acquired in steps S1001 and S1002. FIG. 11 shows a graph showing a change in scroll speed when scrolling in the normal mode. In the graph of FIG. 11, the vertical axis represents speed and the horizontal axis represents time. The scroll speed acquired in step S1001 is the speed at the time of scroll start 1101. From here, the scroll speed is gradually reduced according to the deceleration acquired in step S1002. In FIG. 11, the scroll speed starts to decrease from the time of deceleration start 1102 and is continuously decreased until the scroll end 1103. Since the scroll speed becomes “0” at the end of the scrolling 1103, the scrolling is finished (stopped). The scroll control instructing unit 213 issues an instruction to the scroll control unit 204 so as to perform such scrolling, thereby controlling the scrolling. Further, when the process returns from step S1005 described later, the current scroll is continued using the scroll speed and the deceleration acquired in steps S1001 and S1002 instead of restarting the scroll. To do.

  In step S1005, it is determined whether or not the scrolling is finished. More specifically, when the scroll end time 1103 is reached, or when a touch operation on the scrolling form data browsing screen 400 is received from the user, the scrolling is finished when there are no more pages to be scrolled. Is determined. If it is determined that the scrolling has ended, the scrolling process is terminated and the process returns to the caller. If it is not determined that the scrolling has ended, the process returns to step S1004 and the scrolling continues until it is determined that the scrolling has ended.

  On the other hand, when it is determined in step S1003 that the scroll mode 612 is not “0” (when it is determined that the mode is the deceleration mode), in step S1006, similarly to step S1004, the scroll speed acquired in steps S1001 and S1002 is determined. Each page of the form data is scrolled using the deceleration. Also, when processing returns from step S1008, step S1009, and step S1015, which will be described later, the scroll speed and deceleration acquired in steps S1001 and S1002 are used instead of restarting the scroll. Continue the current scroll.

  In step S1007, it is determined whether or not the annotation added to the page of the form data being scrolled is displayed on the display unit 202 by scrolling in step S1006. That is, it is determined whether the annotation has appeared in the form data display area 401 by scrolling. If it is determined that the annotation is displayed, the process proceeds to step S1009. If it is determined that no annotation is displayed, the process proceeds to step S1008.

  In step S1008, similarly to step S1005, it is determined whether or not the scrolling has ended. If it is determined that the scrolling has ended, the scrolling process is terminated and the process returns to the caller. If it is determined that scrolling has not ended, the process returns to step 1006. That is, if no annotation is displayed, steps S1009 to S1015 described later are not executed even in the deceleration mode.

  In step S1009, it is determined whether or not the annotation displayed by scrolling is a target annotation for reducing the scroll speed. More specifically, it is as follows. When both the deceleration mode option A613 and the deceleration mode option B614 are “0”, any annotation is displayed as an annotation to be decelerated if the annotation is displayed. When the annotation option 611 is “0”, the annotations of other generations are not displayed, and thus are not targeted for deceleration.

  When the deceleration mode option A 613 is “1”, when the displayed annotation type 625 is “stamp”, it is not targeted for deceleration. In the present embodiment, when the displayed annotation type 625 is “memo”, the object is to be decelerated. When the deceleration mode option B 614 is “1”, when the displayed annotation is an annotation of another generation, it is not targeted for deceleration. That is, only the annotation of the currently displayed generation is targeted for deceleration. In this way, the annotation to be decelerated is determined according to the setting (condition) made on the setting screen 500.

  If it is determined that the annotation displayed by scrolling is an annotation to be reduced in scrolling speed, the process proceeds to step S1010. If it is determined that the annotation displayed by scrolling is not an annotation to be reduced in scrolling speed, the process returns to step S1006.

  In step S1010, the number of annotations determined to be decelerated among the displayed annotations is counted. The more annotations there are, the more time is required for the user to confirm the annotations. Therefore, in step S1010, the annotations to be decelerated are counted, and the scroll speed is controlled according to the number.

  In step S1011, the scroll speed calculation unit 212 is used to calculate a scroll speed for allowing the user to check the annotation. For example, the time for the user to confirm one annotation is determined in advance, and the total time to be confirmed is calculated using the displayed number of annotations to be decelerated and the corresponding time, and the annotation to be decelerated for the total time is calculated. Is controlled so as to be displayed in the form data display area 401. By doing so, when there is an annotation to be decelerated, the user can confirm the annotation by reducing the scroll speed to a slower scroll speed than the scroll speed calculated in step S1101.

  In step S1012, the current scroll speed is temporarily stored in the RAM 103. Since the current scroll speed changes with the passage of time, the scroll speed is acquired from the scroll control unit 204 and stored in the RAM 103.

  In step S1013, the scroll speed calculated in step S1011 is decreased to scroll each page of the form data. When controlling the scroll speed, the scroll speed is controlled by issuing an instruction from the scroll control instruction section 213 to the scroll control section 204, as in step S1004. In addition, it is desirable not to use the deceleration acquired in step S1002 in this scroll. That is, it is preferable to scroll at a constant reduced speed. Thereby, it is possible to prevent the scrolling from being stopped due to the annotation being displayed.

  In step S1014, it is determined whether or not the displayed annotation to be decelerated has moved out of the form data display area 401 (display has ended) after decelerating and scrolling in step S1013. If it is determined that the displayed annotation to be decelerated is out of the form data display area 401, the process proceeds to step S1015. If it is determined that the displayed annotation to be decelerated is not outside the form data display area 401, the process returns to step S1013 to continue scrolling at the reduced scroll speed.

  In step S1015, the original scroll speed temporarily stored in step S1012 is acquired from the RAM 103. Then, the process is returned to step S1006, and each page of the form data is scrolled using the scroll speed and the deceleration obtained in steps S1001 and S1002. In particular, when scrolling is started, control is performed so that scrolling is resumed at the scroll speed acquired in step S1015. By doing so, scrolling can be resumed at the scroll speed before the deceleration in step S1013.

  FIG. 12 is a diagram illustrating a case where the form data whose form ID 601 is “REP003” is scrolled. In the scroll of FIG. 12, since the annotation option 611 is “0”, annotations of other generations are not displayed. The scroll mode 612 is “1”, the deceleration mode option A613 is “1”, and the deceleration mode option B614 is “1”. A graph showing the change in the scroll speed is the graph of FIG. The scroll speed control when the annotation to be decelerated is displayed will be described with reference to FIGS. 12 and 13.

  First, the scroll speed is calculated according to the flick operation from the user, and set as the scroll speed at the time of the scroll start 1301 in FIG. The form data browsing screen 400 at this time is as indicated at 1200. Since there is no annotation at this point, scrolling is started as in the normal mode.

  Then, when the form data browsing screen 400 is in a state as indicated by 1210 by scrolling, the annotation of the memo to be decelerated is displayed, so that the scrolling speed is reduced. This is the point in time when annotation display starts 1302. It turns out that it is decelerating from the original speed. While the annotation is being displayed (1220 in FIG. 12), scrolling is performed at a reduced constant speed, as indicated by 1303 during annotation display. That is, the annotation is scrolled at such a speed that the user can confirm it. When the passage of the annotation ends (1230 in FIG. 12), as shown in the annotation display end 1304, the speed is returned to the speed at the start of the annotation display 1302, and scrolling is performed while gradually decelerating using the deceleration. In other words, the scrolling speed is temporarily reduced to confirm the annotation, but when the annotation display is finished, the scrolling can be continued by returning to the original scrolling speed.

  In this embodiment, when the passing of the annotation is completed, the scrolling is continued by returning to the scrolling speed before the annotation is displayed. However, as shown in FIG. You may continue scrolling at speed. In the case of FIG. 13, even after deceleration by annotation display, the same deceleration as before deceleration is used, so that there is a problem that the scrolling distance increases if there is an annotation. Therefore, as shown in FIG. 14, the problem of FIG. 13 is solved by controlling the scroll at a different speed only while the annotation is displayed, based on the scroll speed when the annotation is not displayed. .

  As described above, according to the present embodiment, even when scrolling a page constituting the form data, there is an effect that the annotation attached to the page can be confirmed while continuing scrolling.
