Description

  The present invention relates to an information processing apparatus and a program for performing action determination of an operation related to a slide and an operation related to a select.

  In recent years, many information processing apparatuses equipped with a touch panel, such as mobile phones and car navigation devices, have become widespread. When the user performs an operation on the touch panel, these devices recognize and execute a command corresponding to the type of operation.

  The types of operations that the user can perform on the touch panel can be broadly divided into operations related to the selection of pressing icons on the screen (select operation), and slides that move up, down, left and right with the finger on the screen. There are two types of operations (slide system operations).

  Here, in the information processing apparatus, the operation position on the touch panel is detected in a unit as small as a dot unit with respect to the operation performed by the user on the touch panel. For this reason, even if the user intends to perform a select-type operation, if the user unconsciously moves the finger on the touch panel even when the finger is released from the touch panel, the operation is Is mistakenly recognized as a slide system operation.

  In order to cope with such a problem, Patent Literature 1 detects a touched (pressed) point and an untouched (released) point in an operation performed on the touch panel, and a moving distance during the operation. A method for determining the type of operation according to the method is described (see Patent Document 1).

JP 2009-151691 A JP 2009-244967 A

  By the way, in a slide system operation such as flick operation that quickly moves on the touch panel, the user unconsciously lifts the finger on the touch panel immediately before moving the finger on the touch panel ( Or the pressing force may be weakened). In particular, in the case of a resistive touch panel, it is not recognized that the finger is touching the touch panel unless there is an appropriate pressure, so even if the touch is lightened, it is recognized that the finger has left the touch panel. In the method described in Patent Document 1, it is determined whether the operation is a select-type operation or a slide-type operation based on a moving distance from when it is touched to when it is untouched. When it is recognized that the user has left, since the moving distance up to that point is small, it is recognized that the select operation has been performed. For example, when a flick operation is performed on a certain icon, if the finger is removed from the touch panel immediately before the finger is moved as described above, it is recognized that the select operation has been performed on the icon.

  In Patent Document 2, when a touch panel is touched (pressed) when performing a select operation, an area for calculating an average value of detection positions is set around the touched position, and is untouched (released). Even if the position is outside the area, a method is described in which the deviation of the operation position can be suppressed by determining the calculated average value as the final position. Is a method for determining an operation position, and does not prevent a slide system operation from being erroneously determined as a select system operation.

  The present invention is intended to solve the above-described problem, and suppresses erroneous determination of an operation related to a slide and an operation related to a selection performed on a touch panel, and realizes an operation requested by a user more faithfully. An object of the present invention is to provide an information processing apparatus and a program that can be used.

  The operation display unit 30 includes a display unit 31 and an operation unit 32. Among these, the operation unit 32 includes a switch unit 33 such as a start button and a touch panel unit 34. The display unit 31 is composed of a liquid crystal display (LCD) and the like, and has a function of displaying various operation screens, setting screens, and the like.

  The touch panel unit 34 is provided on the screen of the display unit 31. The touch panel unit 34 detects a coordinate position on the touch panel unit 34 where the screen is pressed with a touch pen or a finger. In the present embodiment, the touch panel unit 34 is a resistive film type touch panel, and detects a position pressed with a pressing force of a certain level or more. The CPU 11 determines whether the operation related to the pressing is a flick operation or a selection operation from the time-series change of the pressing force detected by the touch panel unit 34 and the change of the coordinates of the pressing position.

  The information processing apparatus 10 displays a plurality of icons or the like in a display area within the screen of the display unit 31, and the touch panel unit 34 performs an operation for selecting the icon or an operation for the displayed page itself (advancing the page). Etc.) from the user. For example, when performing copying or the like, settings such as monochrome / color selection and paper selection are accepted by operating the icon. At this time, the icons that are not displayed on the screen can be selected by the user by advancing or returning the page. The operation can be performed with a pen, a finger, and the like, but will be described as an operation with a finger hereinafter.

  Here, there are three types of operations that the information processing apparatus 10 accepts from the user: a select operation, a flick operation, and a drag operation. The select operation is an operation of pressing a predetermined coordinate on the touch panel unit 34 and releasing the finger with little movement. The flick operation is an operation of pressing a predetermined coordinate on the touch panel unit 34 and quickly paying it in any direction, up, down, left, or right. Note that the finger is released from the touch panel unit 34 at the end of the paying operation. The drag operation is an operation of pressing a predetermined coordinate on the touch panel unit 34, slowly moving the finger up and down, left and right as it is, and releasing the finger from the touch panel unit 34 after the movement of the finger is stopped.

  In addition, when the user performs a flick operation or a drag operation, the CPU 11 recognizes that the press on the touch panel unit 34 is weakened just before the finger is moved and the user's finger is released. Even if the operation is to be performed, a function is provided for determining that the operation is not a select operation but a flick operation or a drag operation according to the user's request.

  FIG. 2 shows how the user performs a flick operation on the selection screen 40 being displayed on the touch panel unit 34. The selection screen 40 has a setting content display 41 in the center, a home screen transition icon 42 in the upper left, a status display field 43 in the upper center, a page number display 44 in the upper right, and four selection icons 45 (45A, 45B in the lower part). , 45C, 45D) are displayed side by side. The user can select items such as the home screen transition icon 42 and the selection icon 45 (45A, 45B, 45C, 45D) by the selection operation.

  The selection icons 45 (45A, 45B, 45C, 45D) include a large number of selection icons 45 in addition to the four selection icons 45 currently displayed. It cannot be displayed. Therefore, when a flick operation or a drag operation in the left or right direction (X-axis direction on the touch panel unit 34) is received from the user with respect to the selection icon 45 displayed on the display unit 31, the selection icon 45 is displayed. The column is moved in the direction of the flick operation or drag operation, and the selection icon 45 that has not been displayed is displayed.

  The page number display 44 indicates that the currently displayed page is the second of the three pages. The page is the entire screen displayed on the display unit, and the currently displayed page is a setting screen related to copying. The contents of other pages include a setting screen related to facsimile communication, a setting screen related to a box, and a setting screen related to e-mail. The touch panel 34 is displayed on the first page when the user performs a flick operation from left to right on the margin on the selection screen 40, and on the third page when the user performs a flick operation from right to left. Switch the page to be used.

  In FIG. 2, the user presses the portion where the selection icon 45 </ b> C is displayed for the purpose of displaying the selection icon 45 that is not currently displayed, and the finger that is pressed as it is on the X axis on the touch panel unit 34. Flick operation to pay quickly in the direction. However, it is assumed that the user weakens the pressing force on the touch panel unit 34 immediately before moving the finger, and thus the CPU 11 recognizes that the user's finger is separated from the touch panel unit 34 (Case 1). And).

  FIG. 3 shows a flicking time pressing force graph 50 representing the relationship between the pressing force applied to the touch panel unit 34 and time when the flick operation of the case 1 is performed. A threshold value of the pressing force recognized by the touch panel unit 34 when the user touches the touch panel unit 34 is set as a pressing threshold value 51. The portion of the flicking pressing force graph 50 in a state where the touch panel unit 34 recognizes that the user is touching the touch panel (a state in which the pressing force exceeds the pressing threshold 51) is displayed and recognized by a solid line. The portion in the absence state (the state where the pressing force is below the pressing threshold value 51) is indicated by a broken line.

  4 shows the finger position on the X coordinate (the horizontal coordinate on the touch panel unit 34, see FIG. 2) and the time when performing the flick operation of the case 1 as in the flicking pressure graph 50 of FIG. A flick movement graph 60 showing the relationship is shown. Note that the state where the touch panel unit 34 recognizes that the user is touching the touch panel (the state where the pressing force exceeds the pressing threshold value 51) is indicated by a solid line, and the state where the user does not recognize (the pressing force is pressed). The portion in the state of being below the threshold value 51 is indicated by a broken line.

  With reference to FIGS. 3 and 4, the operation state when performing the flick operation is divided into three stages (S1, S2, S3), and the pressing in each state and the change of the position on the X coordinate will be described. When the pressing force falls below the pressing threshold value 51 and becomes the pressing threshold value 51 or more, the pressing event (touch operation) is set, and when the pressing force exceeds the pressing threshold value 51 and becomes the pressing threshold value 51 or less. Release event (release action). The touch panel unit 34 recognizes that the user has started pressing the touch panel unit 34 when a press event occurs, and recognizes that the user's finger has left the touch panel unit 34 when a release event occurs.

・ S1 in FIG. 3 and FIG. 4 <A state in which the pressed finger is stopped>
First, the user starts touching (pressing) the touch panel unit 34. When the pressing force starts to rise and exceeds the pressing threshold value 51, the first press event (press event 1) occurs. Eventually, the increase in pressing force stops (see FIG. 3). Thereafter, immediately before the user moves the finger, the pressing force on the touch panel unit 34 is weakened. In S1, since the finger is in a stopped state, the flick movement graph 60 does not change on the X coordinate (see FIG. 4).

・ S2 in FIG. 3 and FIG.
When the weakened pressing force falls below the pressing threshold value 51, an initial release event (referred to as release event 1) occurs. Thereafter, the movement of the finger is started, and the pressing force rises again and exceeds the pressing threshold value 51, whereby a second press event (referred to as press event 2; see FIG. 3) occurs. In S2, the position on the X coordinate starts to move in accordance with the start of finger movement (see FIG. 4).

S3 in FIGS. 3 and 4 <A state where the finger is moving on the touch panel unit 34>
The pressing force when the finger is moving on the touch panel unit 34 is stable in a state where the pressing threshold value 51 is exceeded. Since the operation is a flick operation, the pressing force gradually decreases at the end of the operation, and the pressing force becomes 0 when the finger is released from the touch panel unit 34 (see FIG. 3). A second release event (release event 2) occurs when the pressing force falls below the pressing threshold 51. In S3, the position on the X coordinate moves with the movement of the finger (see FIG. 4). When the finger is removed from the touch panel unit 34, the graph is interrupted and ends.

  FIG. 5 shows a state where the user performs a drag operation on the selection screen 40 displayed on the touch panel unit 34. Similar to FIG. 2, the selection screen 40 has a setting content display 41 in the center, a home screen transition icon 42 in the upper left, a status display field 43 in the upper center, a page number display 44 in the upper right, and four selection icons 45 in the lower part. (45A, 45B, 45C, 45D) are displayed side by side.

  In FIG. 5, for the purpose of displaying the selection icon 45 that is not currently displayed, the user presses the portion where the selection icon 45 </ b> C is displayed, and the finger that is pressing is directly on the touch panel unit 34. A drag operation is performed by a series of actions of slowly moving in the X-axis direction. However, the user weakens the pressing force on the touch panel unit 34 immediately before moving the finger, and the CPU 11 recognizes that the user's finger has moved away from the touch panel unit 34. (Case 2).

  FIG. 6 shows a drag pressure graph 52 representing the relationship between the pressure applied to the touch panel unit 34 and time when the case 2 drag operation is performed. In the dragging pressure graph 52, the portion of the state where the touch panel unit 34 recognizes that the user is touching the touch panel (the state where the pressing force exceeds the pressing threshold 51) is displayed and recognized by a solid line. The portion in the absence state (the state where the pressing force is below the pressing threshold value 51) is indicated by a broken line.

  FIG. 7 shows the position of the finger on the X coordinate (the horizontal coordinate on the touch panel unit 34, see FIG. 5) and the time when performing the drag operation of the case 2 as in the drag pressure graph 52 in FIG. A drag movement graph 61 representing the relationship is shown. Note that the state where the touch panel unit 34 recognizes that the user is touching the touch panel (the state where the pressing force exceeds the pressing threshold value 51) is indicated by a solid line, and the state where the user does not recognize (the pressing force is pressed). The portion in the state of being below the threshold value 51 is indicated by a broken line.

  With reference to FIGS. 6 and 7, the operation state when performing the drag operation is divided into three stages (S1, S2, S3), and the pressing force and the change of the position on the X coordinate in each state will be described. .

-S1 in FIG. 6, FIG. 7 <The state where the pressed finger is stopped>
First, the user starts touching (pressing) the touch panel unit 34. When the pressing force starts to rise and exceeds the pressing threshold value 51, the first press event (press event 1) occurs. Eventually, the increase in pressing force stops (see FIG. 6). Thereafter, immediately before the user moves the finger, the pressing force on the touch panel unit 34 is weakened. In S1, since the finger is in a stopped state, the movement graph 61 during drag does not change on the X coordinate (see FIG. 7).

S2 in FIG. 6 and FIG. 7 <Starting movement of finger pressing>
When the weakened pressing force falls below the pressing threshold value 51, an initial release event (referred to as release event 1) occurs. Thereafter, the movement of the finger is started, and the pressing force rises again and exceeds the pressing threshold value 51 to generate a second press event (referred to as press event 2; see FIG. 6). In S2, the position on the X coordinate starts to move in accordance with the start of finger movement (see FIG. 7).

S3 in FIG. 6 and FIG.
The pressing force when the finger is moving on the touch panel unit 34 is stable in a state where the pressing threshold value 51 is exceeded. Since the operation is a drag operation, when the movement is finished, the finger is stopped and then released from the touch panel unit 34. The pressing force is stable until the movement is completed. When the finger is removed from the touch panel unit 34, the pressing force becomes zero (see FIG. 6). A second release event (release event 2) occurs when the pressing force falls below the pressing threshold 51. In S3, the position on the X coordinate moves in accordance with the movement of the finger, and the position on the X coordinate also stops in accordance with the end of the movement of the finger (see FIG. 7). When the finger is removed from the touch panel unit 34, the graph is interrupted and ends.

  FIG. 8 shows a state where the user performs a selection operation on the selection screen 40 being displayed on the touch panel unit 34. Similar to FIGS. 2 and 5, the selection screen 40 has a setting content display 41 in the center, a home screen transition icon 42 in the upper left, a status display column 43 in the upper center, a page number display 44 in the upper right, and four in the lower part. Selection icons 45 (45A, 45B, 45C, 45D) are displayed side by side.

  FIG. 8 illustrates a selection operation in which the user presses the selection icon 45C with a finger and releases the finger in that position for the purpose of setting the content of the selection icon 45C with respect to the currently displayed selection icon 45C. It shows how it is going. However, here, it is assumed that the user's finger has moved slightly just before leaving the touch panel unit 34 (referred to as case 3).

  FIG. 9 shows a pressing pressure graph 53 at the time of selection indicating the relationship between the pressing force applied to the touch panel unit 34 and time when performing the selection operation of the case 3. Of the pressing pressure graph 53 at the time of selection, the portion of the state where the touch panel unit 34 recognizes that the user is touching the touch panel (the state where the pressing force exceeds the pressing threshold 51) is displayed and recognized by a solid line. The portion in the absence state (the state where the pressing force is below the pressing threshold value 51) is indicated by a broken line.

  FIG. 10 shows the position of the finger on the X coordinate (the horizontal coordinate on the touch panel unit 34, see FIG. 5) and the time when performing the selection operation of the case 3 in the same manner as the selection pressing force graph 53 of FIG. A selection movement graph 62 showing the relationship is shown. Note that the state where the touch panel unit 34 recognizes that the user is touching the touch panel (the state where the pressing force exceeds the pressing threshold value 51) is indicated by a solid line, and the state where the user does not recognize (the pressing force is pressed). The portion in the state of being below the threshold value 51 is indicated by a broken line.

  With reference to FIGS. 9 and 10, the pressing force and the change in the position on the X coordinate in the operation state (S1) when performing the selection operation will be described.

S1 in FIG. 9 and FIG. 10 <A state where the pressed finger is stopped>
First, the user starts touching (pressing) the touch panel unit 34. When the pressing force starts to rise and exceeds the pressing threshold value 51, the first press event (press event 1) occurs. Eventually, the increase in pressing force stops (see FIG. 9). Thereafter, the user starts to release the finger from the touch panel unit 34. At this time, the finger slightly moves on the touch panel unit 34 (see FIG. 10). When the finger is released from the touch panel unit 34, the pressing force becomes zero (see FIG. 9). The first release event (release event 1) occurs when the pressing force falls below the pressing threshold 51. When the user starts to release his / her finger from the touch panel unit 34, the position on the X coordinate moves by the amount that the finger has moved on the touch panel unit 34 (see FIG. 10). Note that the time from the occurrence of the press event 1 to the occurrence of the release event 1 is defined as the pressing time in the select operation in case 3.

  FIG. 11 shows the flow of processing (flow 1) for determining the type of operation when an operation on the touch panel unit 34 is received.

  This process is started when a press event is detected. The information processing apparatus 10 monitors the occurrence of a release event (step S101; No), and recognizes the release event (step S101; Yes), that is, changes from a state where the pressing force exceeds the pressing threshold value 51 to a state where it falls below. Then, it progresses to step S102.

  In step S102, it is checked whether or not the distance moved from the recognition of the press event immediately before the release event recognized in step S101 to the recognition of the release event is greater than or equal to the first threshold value. The movement distance may be the distance between the coordinates where the press event occurred and the coordinates where the release event occurred, or the length of the trajectory where the finger moved on the touch panel unit 34 from the press event to the release event.

  If the movement distance is equal to or greater than the first threshold (step S102; Yes), the process proceeds to step S103, and it is checked whether or not the finger acceleration immediately before the release event occurs is equal to or greater than the third threshold. If the acceleration is equal to or greater than the third threshold (step S103; Yes), the user's operation related to the release event is determined as a flick operation, a process corresponding to the flick operation is performed (step S105), and the process is terminated. If the acceleration is less than the third threshold (step S103; No), it is determined that the user operation related to the release event is a drag operation, a process corresponding to the drag operation is performed (step S104), and the process is terminated.

  If the movement distance is less than the first threshold value in step S102 (step S102; No), the time from recognition of the press event immediately before the release event recognized in step S101 to recognition of the release event ( (Pressing time) is checked (step S106). If the pressing time is equal to or greater than the second threshold (step S106; Yes), the user operation related to the release event is determined as a select operation, a process corresponding to the select operation is performed (step S107), and the process is terminated. If the pressing time is less than the second threshold (step S106; No), the process is terminated as it is. The pressing time to be compared with the second threshold may be equal to or longer than the second threshold retroactively from the time when the release event occurs. The time from the previous press event to the release event is necessarily measured and compared with the second threshold. It does not have to be.

  When the flick operation of case 1 described in FIG. 3 and FIG. 4 is applied to the flow 1 of FIG. 11, the movement distance from the press event 1 to the release event 1 (S1) is shorter than the first threshold (step S102; No) and the pressing time is also shorter than the second threshold (step S106; No), and therefore, it is determined that it does not correspond to any of the selection operation, the flick operation, and the drag operation and is ignored. In the operation (S3) from the press event 2 to the release event 2, the movement distance is not less than the first threshold (step S102; Yes), and the acceleration of the finger immediately before the release event occurs is not less than the third threshold (step S103; Yes). Therefore, it is determined as a flick operation.

  When the drag operation of case 2 described in FIG. 6 and FIG. 7 is applied to the flow 1 of FIG. 11, the movement distance from the press event 1 to the release event 1 (S1) is shorter than the first threshold (step S102; No) and the pressing time is also shorter than the second threshold (step S106; No), and therefore, it is determined that it does not correspond to any of the selection operation, the flick operation, and the drag operation and is ignored. As for the operation (S3) from the press event 2 to the release event 2, the movement distance is not less than the first threshold (step S102; Yes), and the acceleration of the finger immediately before the release event occurs is less than the third threshold (step S103; No). Therefore, it is determined as a drag operation.

  When the select operation of case 3 described in FIGS. 9 and 10 is applied to the flow 1 of FIG. 11, the operation (S1) from the press event 1 to the release event 1 has a movement distance less than the first threshold (step S102; No) and the pressing time is equal to or greater than the second threshold (step S106; Yes), it is determined that the selection operation has been performed.

  Note that the first, second, and third threshold values can be appropriately set by the user. The first threshold value may be set to a distance for one icon, for example. The second threshold may be set to a time (for example, about 1 second) during which it can be determined that the operation is a select operation. The third threshold value may be set as appropriate within a range in which a flick operation and a drag operation can be distinguished.

  In the processing shown in FIG. 11, when a finger is released from the touch panel unit 34 (when a release event occurs), from the press event (touching the touch panel unit 34) immediately before the release event until the release event occurs. From the movement distance, the pressing time, and the acceleration immediately before the release, it is determined whether the operation related to the release event is a select operation, a flick operation, a drag operation or an operation to be ignored. As a result, when a flick operation, a drag operation, or the like is performed, an erroneous determination is suppressed even when an operation is performed in which it is recognized that the finger is momentarily separated from the touch panel unit 34 immediately before the finger is moved. The operation desired by the user can be recognized more faithfully.

  In addition, when a plurality of users share the information processing apparatus 10, since each user has a different touch or moving operation (pressing force, moving distance, pressing time, etc.), each operation is determined by one element. Although it is difficult to carry out from (for example, only the movement distance), in the determination method shown in FIG. 11, two or more elements (here, the movement distance until the release event occurs, the pressing time, the acceleration immediately before the release) ), The erroneous determination can be suppressed even if there is a defect for each user.

  FIG. 12 shows a second processing flow (flow 2) for preventing an erroneous determination with respect to an operation in which it is recognized that the finger is separated for a moment.

  This process is started when a press event is recognized. First, the information processing apparatus 10 monitors the occurrence of a release event (step S201; No), and recognizes the release event (step S201; Yes), that is, a state where the pressing force is lower than the state where the pressing threshold value 51 is exceeded. If changed, the process proceeds to step S202.

  In step S202, it is monitored whether or not a new press event is received within a predetermined time after the previous release event has occurred. If no new press event has occurred within the predetermined time (step S202). ; No), it progresses to step S203. When a new press event is received within a predetermined time (step S202; Yes), the process is terminated as it is. For example, the predetermined time may be appropriately set to about 0.2 seconds. When the process is terminated due to the occurrence of a new press event, the process is started again from step S201 by this press event.

  In step S203, it is checked whether the moving distance from the recognition of the press event immediately before the release event recognized in step S201 to the recognition of the release event is equal to or greater than the first threshold value. When the movement distance is less than the first threshold (step S203; No), the user's operation related to the release event recognized in step S201 is determined as a selection operation, and a process corresponding to the selection operation is performed (step S207). The process is terminated.

  When the moving distance is equal to or greater than the first threshold (step S203; Yes), the process proceeds to step S204, and it is checked whether the acceleration immediately before the release event recognized in step S201 is equal to or greater than the third threshold. If the acceleration is equal to or greater than the third threshold (step S204; Yes), it is determined that the user operation related to the release event is a flick operation, a process corresponding to the flick operation is performed (step S206), and the process is terminated. If the acceleration is less than the third threshold (step S204; No), it is determined that the user operation related to the release event is a drag operation, a process corresponding to the drag operation is performed (step S205), and the process is terminated.

  When the flick operation of case 1 described in FIGS. 3 and 4 is applied to the flow 2 of FIG. 12, the operation from the press event 1 to the release event 1 (S1) is the time from the release event 1 to the next press event 2. Is short (FIG. 12, step S202; Yes), it is ignored as it does not correspond to any of the select operation, flick operation, and drag operation. The operation from the press event 2 to the release event 2 (S3) is performed when there is no new press event immediately after the release event 2 (step S202; No), and the moving distance is equal to or greater than the first threshold (step S203; Yes). Since the acceleration of the finger immediately before the occurrence of the event is equal to or greater than the third threshold (step S204; Yes), it is determined that the flick operation is performed.

  When the drag operation of case 2 described in FIGS. 6 and 7 is applied to the flow 2 of FIG. 12, the operation from the press event 1 to the next release event 1 (S1) is the time from the release event 1 to the press event 2. Is short (FIG. 12, step S202; Yes), it is ignored as it does not correspond to any of the select operation, flick operation, and drag operation. The operation from the press event 2 to the release event 2 (S3) is performed when there is no new press event immediately after the release event 2 (step S202; No), and the moving distance is equal to or greater than the first threshold (step S203; Yes). Since the acceleration of the finger immediately before the event occurs is less than the third threshold (step S204; No), it is determined as a drag operation.

  When the select operation in case 3 described in FIGS. 9 and 10 is applied to the flow 2 in FIG. 12, the operation from the press event 1 to the release event 1 (S1) has no new press event immediately after the release event 1. (Step S202; No), since the moving distance is less than the first threshold (Step S203; No), it is determined to be a select operation.

  Note that the user can set the first and third threshold values and the predetermined time as the determination criterion in step S202 as appropriate. The first threshold value may be set to a distance for one icon, for example. The third threshold value may be set as appropriate within a range in which a flick operation and a drag operation can be distinguished. The predetermined time may be appropriately set to, for example, 0.2 seconds within a range in which the operation related to the release event and the operation related to the press event immediately after the release event can be determined as a series of operations.

  In the processing shown in FIG. 12, when a release event occurs, whether or not a new press event has occurred within a predetermined time immediately after the release event, and until the release event occurs from the press event immediately before the release event. Whether the operation related to the release event is a select operation, a flick operation, a drag operation, or an operation to be ignored. As a result, when a flick operation, a drag operation, or the like is performed, an erroneous determination is suppressed even when an operation is performed in which it is recognized that the finger is momentarily separated from the touch panel unit 34 immediately before the finger is moved. The operation desired by the user can be recognized more faithfully.

  The embodiment of the present invention has been described with reference to the drawings. However, the specific configuration is not limited to that shown in the embodiment, and there are changes and additions within the scope of the present invention. Are also included in the present invention.

  In the embodiment of the present invention, there are three types of operations performed by the user: a select operation, a drag operation, and a flick operation, but the present invention is not limited to this. For example, there may be operations such as pinch out and pinch in.

  In the embodiment of the present invention, the first, second, and third threshold values (see FIGS. 11 and 12) and the predetermined time until a new press event (see FIG. 12) are set appropriately by the user. The information processing apparatus 10 accepts the user's select operation, flick operation, drag operation, and the like a plurality of times on a trial basis, and the information processing apparatus 10 based on the time from the press event to the release event related to the operation and the actually measured moving distance. A value that is optimal for the user may be determined. By determining the threshold value for determining the type of operation from the actual measurement value related to the user's operation, it is possible to suppress erroneous determination of each operation under optimum conditions and to recognize the operation desired by the user more faithfully.

  FIG. 13 shows an example of the operation determination learning mode screen 70 displayed on the display unit 31 (touch panel unit 34). On the operation determination learning mode screen 70, an instruction to perform a predetermined operation a predetermined number of times is displayed above the target button 71 with respect to the target button 71 displayed in the center of the screen. Specifically, the user performs a selection operation, a flick operation, and a drag operation on the target button 71 ten times in the order in which they are displayed on the display unit 31, and the information processing apparatus 10 Changes in the coordinates of the pressed position on the touch panel are recorded in time series.

  For the first threshold, the minimum moving distance (or average distance) in the case of flick operation and drag operation and the longest moving distance (or average distance) in the case of select operation are obtained, and the longest moving distance (or average distance) of the select operation is obtained. ) And the minimum moving distance (or average distance) of the flick operation and drag operation, a first threshold value is set.

  As for the second threshold value, an average time (or the longest time) until the pressing force temporarily decreases and becomes less than the pressing threshold value 51 after the start of the operation in the flick operation and the drag operation is obtained, and the average pressing time in the select operation The second threshold is set between (or the minimum time).

  As for the third threshold value, in the flick operation, the minimum value (or average value) of the acceleration of the finger immediately before the release event occurs is obtained, and that value is set as the third threshold value.

  The predetermined time in the flow 2 is the time from when the pressing force temporarily decreases after the operation starts in the flick operation and the drag operation to become less than the pressing threshold value 51 until the pressing force increases again and becomes the pressing threshold value 51 or more. The average time or the longest time is set as the predetermined time.

  The first, second, and third threshold values and the predetermined time until a new press event may be set for each user. In that case, a user ID or the like is registered in advance, a user in use is identified by login authentication, and a threshold value registered in association with the user ID of the user being authenticated is employed.

  Although the information processing apparatus 10 itself has been described as an example in the embodiment of the present invention, a program that causes the information processing apparatus 10 to operate as in the embodiment may be used. Further, the information processing apparatus 10 is not limited to an image forming apparatus, and may be another apparatus such as a measuring machine or a scanner.
