Description of the Related Art In recent years, some image forming apparatuses represented by multifunction peripherals (MFPs) include a touch panel, and a user can input an operation using the touch panel. Further, as an operation using the touch panel, a flick operation for sliding a finger on the touch panel is known. For example, Japanese Unexamined Patent Application Publication No. 2011-118629 describes a method for detecting a flick operation and a tap operation. The flick operation is an operation of sliding a finger on the touch panel, and has a sliding direction, speed and distance components. Therefore, the flick operation is convenient when used for scrolling the screen.

However, when flick operations are continuously input in order to scroll the screen in a certain direction, it is necessary to return the finger to the direction opposite to the scroll direction in order to input the next flick operation after inputting the flick operation. . In the process of returning the finger in the direction opposite to the scroll direction, the finger may accidentally touch the touch panel. In this case, a reverse flick operation is input in (a). In particular, MFPs are often provided with a touch panel on the upper surface of the MFP body, and there are many cases where the degree of freedom of changing the relative position between the touch panel and the user is small. For this reason, in the case where the flick operation is continuously input, the probability that an erroneous operation occurs may increase.

Clockwise, upward, rightward, downward, and leftward.

  The direction detection unit 65 is identified by the position information input first using position information input first from the touch panel 165 and position information input after that, for example, position information input last. The direction from the position to the position specified by the position information input last is calculated. The direction detection unit 65 determines any one of the upward direction, the right direction, the downward direction, and the left direction based on the calculated direction. Here, if the direction is indicated by an angle that rotates clockwise with respect to the upward direction, if the calculated direction is −45 degrees (315 degrees) or more and less than 45 degrees, it is upward 45 degrees or more and 135 degrees. If it is less than 135 degrees, it is determined in the right direction, if it is 135 degrees or more and less than 225 degrees, it is determined in the downward direction.

The speed detection unit 67 detects the speed using the position information input first from the touch panel 165 and the position information input thereafter, for example, the position information input last. It is specified by the time between the time when the first position information was input and the time when the last position information was input, the position specified by the first input position information, and the position information input last. The speed is calculated by calculating the distance to the position and dividing the distance by time.

  The distance detection unit 69 detects the distance of the flick operation based on the position information continuously input from the touch panel 165, and outputs the detected distance to the direction determination unit 53 and the flick operation reception unit 57. The distance detector 69 detects the distance using the position information input first from the touch panel 165 and the position information input last. The distance between the position specified by the position information input first and the position specified by the position information input last is calculated.

  The continuous update unit 73 updates the fixed direction with the direction input from the direction detection unit 65 when the direction different from the fixed direction is continuously input from the direction detection unit 65 when the fixed direction is determined. . Specifically, the continuous update unit 73 receives the direction of the flick operation to be processed from the direction detection unit 65 and the cancel signal from the erroneous operation detection unit 55. The continuous update unit 73 is input from the direction detection unit 65 when the direction of the flick operation to be processed input from the direction detection unit 65 immediately after the cancel signal is input from the erroneous operation detection unit 55 is different from the fixed direction. The fixed direction is updated with the direction of the flick operation to be processed. The cancel signal input from the erroneous operation detection unit 55 corresponds to the flick operation detected by the flick operation detection unit 51 immediately before the flick operation to be processed.

  In response to the flick operation detected by the flick operation detection unit 51 immediately before the flick operation to be processed, the continuous update unit 73 is input from the direction detection unit 65 when no cancel signal is input from the erroneous operation detection unit 55. If the direction of the flick operation to be processed is different from the fixed direction, the fixed direction is not updated. The continuous update unit 73 is input from the direction detection unit 65 immediately after the cancel signal is input from the erroneous operation detection unit 55 in response to the flick operation detected by the flick operation detection unit 51 immediately before the flick operation to be processed. If the direction of the flick operation to be processed is the same as the fixed direction, the fixed direction is not updated.

  When the fixed direction is determined, the operation amount update unit 75 determines that the operation amount of the flick operation to be processed is equal to or greater than the threshold value and the direction of the flick operation to be processed is different from the fixing method. Update the fixed direction with the direction of the action flick operation. The operation amount of the flick operation is the speed and distance of the flick operation.

  This will be described more specifically. The operation amount update unit 75 receives the direction of the flick operation to be processed from the direction detection unit 65, the speed of the flick operation to be processed from the speed detection unit 67, and the distance of the flick operation to be processed from the distance detection unit 69.

The distance comparison unit 79 receives the distance of the flick operation to be processed from the distance detection unit 69 and the distance threshold TL from the threshold change unit 61. The distance comparison unit 79 compares the distance of the flick operation to be processed with a distance threshold TL.

  The operation amount update unit 75 is a case where the direction of the flick operation to be processed is different from the fixed direction, and the speed comparison unit 77 determines that the speed of the flick operation to be processed is equal to or higher than the speed threshold value TS. Alternatively, if the distance comparison unit 79 determines that the distance of the flick operation to be processed is equal to or greater than the distance threshold TL, the fixed direction is updated with the direction of the flick operation for processing.

  When the fixed direction is determined by the determination unit 71 before determination, and when the fixed direction is updated by the continuous update unit 73 or the operation amount update unit 75, the direction determination unit 53 erroneously operates the determined or updated fixed direction. Output to the detection unit 55.

The image displayed by display control unit 59 includes an image of data output when MFP 100 executes an application program in addition to an image of data stored in ROM 113 or HDD 115. The data stored in advance in the ROM 113 or the HDD 115 includes an address book or image data. Application programs executed by MFP 100 include, for example, a browsing program for browsing a Web page.

  In response to the input of the flick operation from the flick operation receiving unit 57, the display control unit 59 scrolls the displayed image according to the flick operation. The image is scrolled in the direction of the flick operation at a speed corresponding to the speed of the flick operation. If the flick operation speed is high, the scroll speed is increased. If the flick operation speed is slow, the scroll speed is decreased.

  The display control unit 59 outputs the scroll direction of the image displayed on the display unit 161 to the threshold value changing unit 61. The scroll direction is determined with respect to the display surface of the display unit 161 and includes the longitudinal direction of the display surface of the display unit 161 and the short direction of the display surface.

  The threshold value changing unit 61 sets the speed threshold value TS for the flick operation speed and the distance threshold value TL for the flick operation distance with respect to the scroll direction input from the display control unit 59. The value is determined in advance. Here, as a predetermined value corresponding to the speed threshold value TS, the value when the scroll direction is the longitudinal direction is the first speed threshold value TSL, and when the scroll direction is the short direction, The value is the second speed threshold value TSS. The first speed threshold value TSL is larger than the second speed threshold value TSS. Further, as a predetermined value corresponding to the distance threshold value TL, the value when the scroll direction is the longitudinal direction is set as the first distance threshold value TLL, and the value when the scroll direction is the short direction. Is the second distance threshold TLS. The first distance threshold value TLL is larger than the second distance threshold value TLS. In many cases, the flick operation in the longitudinal direction of the display surface is input faster and longer than the flick operation in the short direction, and conversely, the flick operation in the short direction of the display surface is performed in the longitudinal direction. This is because it is difficult to input a long flick operation earlier than a flick operation.

  The notification unit 63 notifies the user that the reverse flick operation is determined to be an erroneous operation in response to the input of the cancel signal from the erroneous operation detection unit 55. Specifically, the notification unit 63 outputs an error display instruction to the display control unit 59 and causes the display unit 161 to display an image indicating that an erroneous operation has been input. The image indicating that an erroneous operation has been input may be an image of an error message such as “Caution: Flicked in the reverse direction” or an image of an arrow indicating the reverse direction. In addition, the brightness of all or part of the image displayed on the display unit 161 may be temporarily changed, or the color of all or part of the image displayed on the display unit 161 may be temporarily changed. You may let them. Further, the notification unit 63 may generate a sound such as a buzzer sound instead of or in addition to displaying an image indicating that an erroneous operation has been input on the display control unit 59.

  FIG. 5 is a flowchart illustrating an example of the flow of display control processing. The display control process is a process executed by CPU 111 when CPU 111 provided in MFP 100 executes a flick operation reception program stored in ROM 113, HDD 115, or CD-ROM 118. Referring to FIG. 5, CPU 111 displays a screen on display unit 161. The screen displayed on the display unit 161 includes an image of data instructed by the user. Here, a case where a screen for displaying an address book is displayed on the display unit 161 will be described as an example. In the next step S02, “0” is set in the variable C in order to initialize the variable C. The variable C is a variable for counting the number of flick operations that are determined to be erroneous operations. In the next step S03, the scroll direction is detected. The scroll direction is determined by the display surface of the display unit 161 and the screen displayed on the display unit 161 in step S01. When the screen displayed on the display unit 161 is displayed so as to be scrollable in the longitudinal direction of the display surface, the scroll direction is the longitudinal direction. When the screen displayed on the display unit 161 is displayed so as to be scrollable in the short direction of the display surface, the scroll direction is the short direction.

  In the next step S04, the process is branched depending on the scroll direction detected in step S03. If the scroll direction is the long direction, the process proceeds to step S05. If the scroll direction is the short direction, the process proceeds to step S06.

  In step S05, the first speed threshold value TSL is set as the speed threshold value TS for the flick operation speed, and the first distance threshold value is set as the distance threshold value TL for the flick operation distance. A value TLL is set, and the process proceeds to step S07. On the other hand, in step S06, the second speed threshold value TSS is set to the speed threshold value TS for the flick operation speed, and the second distance threshold value TL is set to the distance threshold value TL for the flick operation distance. A threshold value TLS is set, and the process proceeds to step S07. In many cases, the flick operation in the longitudinal direction of the display surface is input faster and longer than the flick operation in the short direction, and conversely, the flick operation in the short direction of the display surface is performed in the longitudinal direction. This is because it is difficult to input a long flick operation earlier than a flick operation.

  In step S07, it is determined whether a flick operation has been detected. If a flick operation is detected, the process proceeds to step S08; otherwise, the process proceeds to step S17. In step S17, it is determined whether an end operation has been accepted. Of the hard keys included in the hard key unit 167 included in the operation unit 163, when a hard key to which an end instruction is assigned in advance is pressed by the user, the end operation is accepted. If an end operation has been accepted, the process ends. If not, the process returns to step S07.

  In step S08, it is determined whether the value of timer T is greater than or equal to threshold value TH. The timer T measures the interval between flick operations that are continuously input. If the value of timer T is equal to or greater than threshold value TH, the process proceeds to step S09; otherwise, the process proceeds to step S12. In step S12, timer T is started and the process proceeds to step S13. If step S08 is executed first after the display control process is started, the process proceeds to step S09.

  In step S09, the fixing direction is reset, and the process proceeds to step S10. The fixed direction reset is set in a state where the fixed direction is not set. When the timer T is equal to or greater than the threshold value TH, it is determined that the flick operation is not continuously input, and the fixed direction is reset. Then, the timer T is started (step S10), the variable C is set to “0” (step S11), and the process proceeds to step S13.

  In step S13, an erroneous operation determination process is executed, and the process proceeds to step S14. Although details of the erroneous operation determination process will be described later, it is a process for determining whether or not the flick operation detected in step S07 is an erroneous operation. When it is determined that the flick operation is not an erroneous operation, it is determined that the flick operation detected in step S07 is accepted. If it is determined that the operation is erroneous, the flick operation detected in step S07 is determined to be invalid. In step S14, the process branches depending on the determination result of the erroneous operation determination process. If the determination result indicates that the flick operation is accepted, the process proceeds to step S15. If the determination result indicates that the flick operation is invalidated, the process proceeds to step S16.

  In step S15, a scroll process is executed, and the process returns to step S07. Since the scroll process is well known, detailed description will not be repeated. However, the screen displayed on the display unit 161, here the screen displaying the address book, is displayed in the direction of the flick operation detected in step S07. Scroll at a speed corresponding to.

  On the other hand, in step S16, an erroneous operation is notified and the process returns to step S07. Specifically, an image indicating that an erroneous operation has been input is displayed on the display unit 161.

  FIG. 6 is a flowchart illustrating an example of the flow of erroneous operation determination processing. The erroneous operation determination process is a process executed in step S13 of FIG. In a stage before the erroneous operation determination process is executed in step S13 of FIG. 5, a flick operation is detected in step S07. In the operation determination process, the flick operation detected in step S07 is processed.

  Referring to FIG. 6, CPU 111 determines whether or not a fixed direction is set (step S21). If the fixed direction is set, the process proceeds to step S22; otherwise, step S22 is skipped and the process proceeds to step S24. In step S22, it is determined whether the speed of the flick operation to be processed is equal to or greater than the speed threshold value TS. If the speed of the flick operation is greater than or equal to speed threshold value TS, the process proceeds to step S24; otherwise, the process proceeds to step S23.

  In step S23, it is determined whether the distance of the flick operation to be processed is equal to or greater than the distance threshold TL. If the flick operation distance is equal to or greater than distance threshold TL, the process proceeds to step S24; otherwise, the process proceeds to step S25. In step S24, the direction of the processing-target flick operation is set to a fixed direction, and the process proceeds to step S29.

  When the process proceeds to step S25, the fixed direction is set, and the flick operation speed is less than the speed threshold TS and the flick operation distance is less than the distance threshold TL. It is. In step S25, it is determined whether or not the direction of the flick operation to be processed is the same as the fixed direction. If the direction of the flick operation to be processed is the same as the fixed direction, the process proceeds to step S29; otherwise, the process proceeds to step S26.

  In step S26, the value of variable C is incremented by “1”, and the process proceeds to step S27. In step S27, it is determined whether or not the value of variable C is equal to “2”. If the value of variable C is equal to “2”, the process proceeds to step S28; otherwise, the process proceeds to step S31. In step S31, the flick operation to be processed is set to be invalid, and the process returns to the display control process.

  In step S28, the direction of the flick operation to be processed is set to a fixed direction, and the process proceeds to step S29.

  When the process proceeds to step S29, the fixed direction is not set, or the fixed direction is set, and the speed of the flick operation to be processed is equal to or higher than the speed threshold TS. Alternatively, the distance of the flick operation to be processed is equal to or larger than the distance threshold TL, or the direction of the flick operation to be processed is the same as the fixed direction. In step S29, variable C is set to “0”, and the process proceeds to step S30. In step S30, the setting is made to accept the flick operation to be processed, and the process returns to the display control process.

  For this reason, if the direction of the flick operation continuously input during the time less than the threshold value TH is different, the flick operation input later is invalidated in step S31, so the flick operation is continuously performed in the same direction. When inputting an operation, a flick operation that is detected when the touch panel 165 is accidentally touched when the finger or the stylus pen is returned is invalidated. For this reason, it is possible to facilitate an operation of inputting flick operations continuously in the same direction.

  In addition, when flick operations are continuously input in the reverse direction after continuous flick operations are input in the same direction, the first flick operation in the reverse direction is invalidated, but the second flick operation in the reverse direction is invalidated. Accepted. In addition, since the reverse direction is set as the fixed direction, a flick operation that is subsequently input in the fixed direction (reverse direction) is accepted. For this reason, it is possible to facilitate the operation of changing the direction of the flick operation to the reverse direction after inputting the flick operation continuously in the same direction. In addition, when the flick operation in the reverse direction is continuously received three times or more, the flick operation in the approximate direction may be received. In this case, what is necessary is just to set the threshold value compared with the variable C in step S27 to 3 or more.

  Furthermore, after inputting flick operation continuously in the same direction, when inputting flick operation at a speed equal to or higher than the threshold value TS for speed in the reverse direction, or exceeding the threshold value TL for distance in the reverse direction When a flick operation with a distance of is input, a reverse flick operation is accepted. For this reason, it is possible to facilitate the operation of changing the direction of the flick operation to the reverse direction after inputting the flick operation continuously in the same direction.

  As described above, MFP 100 according to the present embodiment functions as an image forming apparatus, determines a fixed direction based on the direction of the flick operation, and the direction of the flick operation to be processed that is detected after the fixed direction is determined. If is different from the fixed direction, the flick operation to be processed is invalidated. For this reason, when the flick operation in the same direction is continuously input, it is possible to determine that the flick operation in the opposite direction is an erroneous operation, and it is possible to facilitate the flick operation to input continuously in the same direction.

  In addition, when the fixed direction is determined, the processed flick operation detected immediately before the processing target flick operation is invalidated, and the direction of the processing target flick operation is the fixing method. If they are different, the fixed direction is updated with the direction of the flick operation to be processed. For this reason, since the fixed direction is updated when the flick operation in a direction different from the fixed direction is continued, the user can easily input the flick operation in the reverse direction and the reverse flick operation in an easy operation. You can switch to operation.

  Further, if the fixed direction is determined, and the speed of the flick operation to be processed is equal to or higher than the speed threshold TS, and the direction of the flick operation to be processed is different from the fixed method, the processing Update the fixed direction with the direction of the action flick operation. For this reason, it is possible to switch to a reverse flick operation by a simple operation of inputting a flick operation different from the fixed direction when the speed is equal to or higher than the speed threshold value TS.

  Further, if the fixed direction is determined, and the distance of the flick operation to be processed is greater than or equal to the distance threshold TL, and the direction of the flick operation to be processed is different from the fixing method, the processing Update the fixed direction with the direction of the action flick operation. For this reason, it is possible to switch to a reverse flick operation by a simple operation of inputting a flick operation different from the fixed direction when the distance is equal to or greater than the distance threshold TL.

  Further, the threshold value TS for the speed and the threshold value for the distance are displayed when the screen is displayed on the display unit 161 so as to be scrollable in the longitudinal direction and when it is displayed so as to be scrollable in the short direction. Since the values TL are different, it is possible to improve the accuracy of detecting an operation for switching to a reverse flick operation.

  Further, when the flick operation is invalidated, the user is notified by text, image, or sound, so that the user can know that the flick operation has been invalidated.

  In addition, the touch panel 165 and the MFP 100 are provided on the top surface of the main body, and it is possible to easily perform a continuous input flick operation on an apparatus with a small degree of freedom in changing the relative position between the user's hand position and the touch panel 165 position. can do.

  In the above-described embodiment, the MFP 100 has been described as an example of the image forming apparatus. However, the image forming apparatus may be a printer, a facsimile, or the like as long as the apparatus can accept a flick operation. Further, the present invention is understood as a flick operation reception method for causing MFP 100 to execute the display control processing shown in FIGS. 5 and 6 and a flick operation reception program for causing CPU 111 of MFP 100 to execute the flick operation reception method. Needless to say, you can.

  The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
