  The operation unit 47 includes a display display 473, a touch panel 472, and operation keys 471.

  The display 473 is configured by a liquid crystal display (LCD) or an organic EL (Organic Light-Emitting Diode) display. The display 473 displays a setting menu and the like related to image formation based on control by the information processing unit 106 described later of the control unit 10.

  The operation keys 471 are, for example, a menu key for calling a menu, an arrow key for moving the focus of a GUI constituting the menu, a determination key for performing a confirmation operation on the GUI constituting the menu, a numerical key, and the like, and a display display 473. An operation for the setting menu displayed on the screen is received from the user.

  The touch panel 472 is a so-called resistive film type or capacitive type touch panel. The touch panel 472 is disposed on the front surface of the display display 473 as a contact detection unit, and detects contact by the user on the display screen of the display display 473 together with the contact position. When the touch panel 472 detects contact by the user, the touch panel 472 outputs a signal indicating the coordinate position of the contact point to a gesture detection unit 101 described later of the control unit 10.

  The control unit 10 further includes a gesture detection unit 101, a gesture operation storage unit 102, an operation error determination unit 103, a priority determination unit 104, a priority storage unit 105, and an information processing unit 106.

Alternatively, the control unit 10 may function as each unit by including a dedicated hardware circuit corresponding to each unit.

  The gesture detection unit 101 detects a predetermined gesture based on a touch input on the touch panel 472. Specifically, the gesture detection unit 101 receives a signal indicating the coordinate position of the contact point output from the touch panel 472, and identifies a predetermined gesture from the transition of the coordinate position.

  Examples of the predetermined gesture include “swipe operation”, “pinch operation”, “rotation operation”, “two-finger swipe operation”, and the like. The swipe operation is an operation of touching the touch panel 472 with one finger and moving the finger while the finger is placed on the touch panel 472. Gesture detection unit 101 detects a swipe operation when there is one contact point on touch panel 472 and the contact point is moving.

  The pinch operation is an operation of touching the touch panel 472 with two fingers and expanding or narrowing the sense of the two fingers while placing the finger on the touch panel 472. The gesture detection unit 101 performs a pinch operation when there are two contact points on the touch panel 472 and the coordinate position of the contact point is changing so that the interval between the two contact points is widened or narrowed. Is detected.

  The rotation operation is an operation of touching the touch panel 472 with two fingers and rotating the two fingers while placing the finger on the touch panel 472. Gesture detection unit 101 detects a rotation operation when there are two contact points on touch panel 472 and the coordinate position of the contact point is changed so that the two contact points rotate.

  The two-finger swipe operation is an operation of touching the touch panel 472 with two fingers and moving the two fingers in the same direction while placing the finger on the touch panel 472. Gesture detection unit 101 detects a two-finger swipe operation when there are two contact points on touch panel 472 and the coordinate position is changed so that the two contact points move approximately in parallel. .

  In addition, the gesture detection unit 101 counts the time (operation time) from when the gesture is detected until it is no longer detected. The gesture detection unit 101 stores the counted operation time in the gesture operation storage unit 102 in the control unit 10.

  The operation error determination unit 103 determines whether or not the gesture detected by the gesture detection unit 101 is due to a user operation error. If the operation time of the gesture stored in the gesture operation storage unit 102 is equal to or less than a predetermined time, the operation error determination unit 103 determines that the gesture is due to a user operation error. Further, if the operation time of the gesture stored in the gesture operation storage unit 102 is not less than a predetermined time, the operation error determination unit 103 determines that the gesture is not due to a user operation error.

  The priority determination unit 104 determines the priority of the gesture based on the determination result by the operation error determination unit 103. Each gesture has a predetermined value as an initial value of the priority, and the priority determination unit 104 increases or decreases the value of the gesture based on the determination result by the operation error determination unit 103. To decide. Specifically, the priority determination unit 104 performs a process of reducing the priority of a gesture that has been determined by the operation error determination unit 103 to be due to a user operation error. In addition, the priority determination unit 104 performs a process of increasing the priority of the gesture for the gesture determined by the operation error determination unit 103 as not due to a user operation error. The priority determination unit 104 stores the determined priority of the gesture in the priority storage unit 105 in the control unit 10.

  FIG. 3 is a diagram illustrating an example of the contents of the gesture priority 1051 stored in the priority storage unit 105. As shown in FIG. 3, the gesture priority 1051 indicates the gesture priority for each type of gesture.

  Here, a case is considered where the gesture detection unit 101 detects a pinch operation and a two-finger swipe operation by simultaneous touch input. At this time, the operation error determination unit 103 determines whether or not the pinch operation and the two-finger swipe operation are due to a user operation error. When it is determined that the two-finger swipe operation is due to a user's operation mistake, the priority determination unit 104 determines, for example, from the priority value “2” of the two-finger swipe indicated by the gesture priority 1051 to “ 1 ”is subtracted and the calculated value is stored in the priority storage unit 105. If it is not determined that the two-finger swipe operation is due to a user operation error, the priority determination unit 104 sets the priority value “2” of the two-finger swipe shown in the gesture priority 1051 to, for example, “1” is added, and the calculated value is stored in the priority storage unit 105.

  The information processing unit 106 performs predetermined information processing corresponding to the gesture detected by the gesture detection unit 101. For example, when the gesture detection unit 101 detects a pinch operation, the information processing unit 106 performs a process of enlarging or reducing the image displayed on the display display 473.

  The information processing unit 106 refers to the priority of the gesture stored in the priority storage unit 105 when the gesture detection unit 101 detects a plurality of gestures by the touch input at the same time. The information processing unit 106 performs information processing corresponding to the gesture when the priority of the gesture is equal to or higher than a predetermined value. When the priority of the gesture is smaller than a predetermined value, the information processing unit 106 does not execute the information processing corresponding to the gesture. Further, when the priorities of the plurality of gestures detected by the touch input at the same time are all lower than a predetermined value, the information processing unit 106 performs information processing corresponding to the gesture having the highest priority among them. Execute.

  The touch panel device according to the first embodiment of the present invention includes the display display 473, the touch panel 472, the gesture detection unit 101, the gesture operation storage unit 102, the operation error determination unit 103, the priority determination unit 104, and the priority storage unit. 105 and an information processing unit 106.

  Below, operation | movement of a touchscreen apparatus provided with said structure is demonstrated.

  FIG. 4 is a flowchart showing an operation flow of the touch panel device according to the first embodiment of the present invention.

  In the following, among the plurality of gestures detected by the simultaneous touch input, the gesture first detected by the gesture detection unit 101 is defined as a first gesture, and the gestures detected after the second are The description will be given as the second gesture.

  The operation of the touch panel device according to the first embodiment of the present invention includes: (1) a step group (steps S10 to S20) for detecting a gesture and performing information processing based on the detected gesture; It consists of a group of steps to be determined (steps S21 to S26).

  The gesture detection unit 101 of the touch panel device according to the first embodiment of the present invention first determines whether or not a first gesture has been detected (step S10).

  When gesture detection unit 101 detects the first gesture (YES in step S10), gesture detection unit 101 stores the operation time of the first gesture in gesture operation storage unit 102 (step S11).

  Thereafter, the information processing unit 106 executes information processing corresponding to the first gesture (step S12).

  The gesture detection unit 101 determines whether the second gesture is detected during the detection of the first gesture (step S13).

  If gesture detection unit 101 detects the second gesture during detection of the first gesture (YES in step S13), gesture detection unit 101 causes gesture operation storage unit 102 to store the operation time of the second gesture. (Step S14).

  The information processing unit 106 determines whether or not the priority of the first gesture stored in the priority storage unit 105 is greater than or equal to a predetermined value (step S15).

  When the priority of the first gesture is equal to or higher than a predetermined value (YES in step S15), information processing unit 106 executes information processing corresponding to the first gesture (step S16).

  If the priority of the first gesture is not equal to or higher than a predetermined value (NO in step S15), the information processing unit 106 does not execute the information processing corresponding to the first gesture and proceeds to the process of step S17.

  The information processing unit 106 determines whether or not the priority of the second gesture stored in the priority storage unit 105 is greater than or equal to a predetermined value (step S17).

  When the priority of the second gesture is equal to or higher than a predetermined value (YES in step S17), information processing unit 106 executes information processing corresponding to the second gesture (step S18).

  If the priority of the second gesture is not equal to or higher than a predetermined value (NO in step S17), information processing unit 106 does not execute the information processing corresponding to the second gesture, and proceeds to step S19.

  The information processing unit 106 determines whether or not the information processing corresponding to the first gesture or the second gesture has been executed after the process of step S15 (step S19).

  If the information processing corresponding to the first gesture or the second gesture has not been executed after the processing of step S15 (NO in step S19), the information processing unit 106 determines the priority of the first gesture and the second The information processing corresponding to the gesture having a higher priority is executed (step S20).

  The above steps S10 to S20 are a group of steps for detecting a gesture and performing information processing based on the detected gesture.

  After the process of step S19 or step S20, a gesture priority determination process (steps S21 to S26) is performed. First, the operation error determination unit 103 determines whether or not the first gesture is due to a user operation error (step S21). If the operation time of the first gesture stored in the gesture operation storage unit 102 is equal to or less than a predetermined time, the operation error determination unit 103 determines that the first gesture is due to a user operation error. If the operation time of the first gesture stored in the gesture operation storage unit 102 is not less than or equal to a predetermined time, the operation error determination unit 103 determines that the first gesture is not due to a user operation error.

  When it is determined that the first gesture is due to a user operation error (YES in step S21), the priority determination unit 104 lowers the priority of the first gesture stored in the priority storage unit 105 ( Step S22).

  When it is determined that the first gesture is not due to a user operation error (NO in step S21), the priority determination unit 104 increases the priority of the second gesture stored in the priority storage unit 105. (Step S23).

  Subsequently, the operation error determination unit 103 determines whether or not the second gesture is due to a user operation error (step S24).

  When it is determined that the second gesture is due to a user operation error (YES in step S24), the priority determination unit 104 lowers the priority of the second gesture stored in the priority storage unit 105 ( Step S25).

  When it is determined that the second gesture is not due to a user operation error (NO in step S24), the priority determination unit 104 increases the priority of the second gesture stored in the priority storage unit 105. (Step S26).

  The above is the description of the operation of the touch panel device according to the first embodiment of the present invention.

  The touch panel device according to the first embodiment of the present invention includes a display 473, a touch panel 472, a gesture detection unit 101, an operation error determination unit 103, a priority determination unit 104, and an information processing unit 106. . The gesture detection unit 101 detects a predetermined gesture based on a touch input on the touch panel 472. The operation error determination unit 103 determines whether or not the gesture detected by the gesture detection unit 101 is due to a user operation error. The priority determination unit 104 determines the priority of the gesture based on the determination result by the operation error determination unit 103. When the gesture detection unit 101 detects a plurality of gestures by touch input at the same time, the information processing unit 106 determines a gesture to be accepted based on the priority, and performs information processing that is determined in advance corresponding to the determined gesture Execute.

  According to the touch panel device according to the first embodiment of the present invention, it is determined whether or not the detected gesture is due to a user's operation error, and information processing corresponding to the gesture is performed based on the priority determined by the determination. Since it is determined whether or not to execute, it is possible to prevent information processing unintended by the user from being executed based on a user's operation mistake.

  In addition, when the gesture detection unit 101 detects a plurality of types of gestures by simultaneous touch input, the information processing unit 106 accepts a gesture having a priority higher than a predetermined value. As a result, the touch panel device according to the first exemplary embodiment of the present invention executes information processing that is not intended by the user even when the gesture detection unit 101 detects a plurality of types of gestures by simultaneous touch input. Can be suppressed.

  Further, the operation error determination unit 103 determines that a gesture whose operation time stored in the gesture operation storage unit 102 is a predetermined time or less among a plurality of gestures detected by the gesture detection unit 101 is due to a user operation error. judge. Thereby, the touch panel device according to the first embodiment of the present invention can specify a gesture that is highly likely to be a gesture based on a user's operation mistake.

<Embodiment 2>
The touch panel device according to the second embodiment is different from the touch panel device according to the first embodiment in that the determination target by the operation error determination unit 103 is the second gesture.

  For example, when the gesture detection unit 101 detects a rotation operation while detecting a pinch operation, the operation error determination unit 103 determines whether or not the operation error is due to a user operation error with respect to the rotation operation that is the second gesture. Determine. On the other hand, the operation error determination unit 103 does not determine whether or not the pinch operation that is the first gesture is due to a user operation error.

  In a touch panel device that can detect two or more contacts, the gesture detection unit 101 may detect a plurality of gestures by simultaneous touch input. There may be a case where a gesture due to a user's operation error is present in a plurality of gestures detected by the touch input at the same time. For example, when the user wants to enlarge an image displayed on the display display 473, the user performs an operation of widening the interval between two fingers placed on the display display 473. If the rotation is not performed, the gesture detection unit 101 detects the rotation operation simultaneously with the pinch operation. As a result, an image that has been subjected to a rotation process that is not intended by the user is displayed on the display 473. Thus, the possibility that the second gesture is due to a user's operation error is higher than the possibility that the first gesture is due to a user's operation error.

  For this reason, the operation error determination unit 103 of the touch panel device according to the second exemplary embodiment determines whether or not the second gesture that is more likely to be a user operation error is due to a user operation error. The first gesture with a low possibility of user's operation mistake is not determined whether or not it is due to the user's operation mistake.

  In the touch panel device according to the second embodiment, the information processing unit 106 determines whether to execute information processing corresponding to the second gesture with reference to the priority of the second gesture. This is different from the touch panel device according to the first embodiment. The information processing unit 106 of the touch panel device according to the second embodiment refers to the priority of the first gesture and does not perform a process of determining whether or not to perform the information processing corresponding to the first gesture.

  Specifically, when the gesture detection unit 101 detects a plurality of gestures by simultaneous touch input, the information processing unit 106 sets the priority of the second gesture stored in the priority storage unit 105. refer. When the second gesture is greater than or equal to a predetermined value, the information processing unit 106 executes information processing corresponding to the second gesture in addition to information processing corresponding to the first gesture. When the second gesture is smaller than a predetermined value, the information processing unit 106 does not execute the information processing corresponding to the second gesture, and executes only the information processing corresponding to the first gesture.

  Next, the operation of the touch panel device according to the second exemplary embodiment will be described. FIG. 5 is a flowchart showing an operation flow of the touch panel device according to the second exemplary embodiment of the present invention. Note that description of the same processing as the processing shown in the flowchart of FIG. 4 is omitted.

  After the gesture detection unit 101 stores the operation time of the second gesture in the gesture operation storage unit 102 (step S <b> 34), the information processing unit 106 stores the second gesture stored in the priority storage unit 105. It is determined whether or not the priority is equal to or higher than a predetermined value (step S35).

  When the priority of the second gesture is not equal to or higher than a predetermined value (NO in step S35), the information processing unit 106 does not execute the information processing corresponding to the second gesture and corresponds to the first gesture. Only information processing is executed (step S36).

  When the priority of the second gesture is equal to or higher than a predetermined value (YES in step S35), information processing unit 106 executes information processing corresponding to the first gesture and the second gesture (step S37). ).

  After the process of step S36 or step S37, the priority determination process of the gesture (steps S38 to S40) is performed. The operation error determination unit 103 determines whether or not the second gesture is due to a user operation error (step S38). If the operation time of the second gesture stored in the gesture operation storage unit 102 is less than or equal to a predetermined time, the operation error determination unit 103 determines that the second gesture is due to a user operation error. If the operation time of the second gesture stored in the gesture operation storage unit 102 is not less than or equal to a predetermined time, the operation error determination unit 103 determines that the second gesture is not due to a user operation error.

  When it is determined that the second gesture is due to a user operation error (YES in step S38), the priority determination unit 104 lowers the priority of the second gesture stored in the priority storage unit 105 ( Step S39).

  When it is determined that the second gesture is not due to a user operation error (NO in step S38), the priority determination unit 104 increases the priority of the second gesture stored in the priority storage unit 105. (Step S40).

  As described above, in the touch panel device according to the second exemplary embodiment, the operation error determination unit 103 is first by the gesture detection unit 101 among the plurality of gestures detected by the gesture detection unit 101 by the touch input at the same time. It is determined whether or not the second gesture excluding the detected first gesture is due to a user operation error. Thereby, the touch panel device according to the second exemplary embodiment of the present invention can determine whether or not the second gesture that may cause the user's operation error is due to the user's operation error. .

  In addition, information processing corresponding to only the first gesture detected first among the plurality of gestures detected by the touch input at the same time is performed, and the second gesture excluding the first gesture is supported. By preventing the information processing from being performed, the information processing corresponding to the second gesture that may cause the user's operation mistake is not performed, and the information processing that is not intended by the user is prevented from being performed. Can be considered. However, in the control of performing information processing corresponding to only the first detected first gesture as described above, even when the user wants to enlarge and rotate the image at the same time, The operation will not be possible.

  On the other hand, in the touch panel device according to the second embodiment, after determining whether or not the second gesture that may cause the user's operation error is due to the user's operation error, It is determined whether or not to perform information processing corresponding to the gesture.

<Embodiment 3>
The touch panel device according to the third exemplary embodiment is different from the touch panel device according to the second exemplary embodiment in the priority content determined by the priority determining unit 104.

  The priority determination unit 104 of the touch panel device according to the third exemplary embodiment determines the priority of the second gesture detected during the detection of the first gesture for each type of the first gesture. The priority determination unit 104 stores the determined priority of the gesture in the priority storage unit 105 in the control unit 10.

  FIG. 6 is a diagram illustrating an example of the contents of the gesture priority 1052 stored in the priority storage unit 105 of the touch panel device according to the third embodiment. As illustrated in FIG. 6, the gesture priority level 1052 indicates second gesture priority levels 1053 to 1056 for each type of the first gesture. As shown in FIG. 7A, the priority 1053 indicates each priority of the second gesture (pinch operation, rotation operation, two-finger swipe operation) when the first gesture is a swipe operation. ing. Further, as shown in FIG. 7B, the priority 1054 includes each priority of the second gesture (swipe operation, rotation operation, two-finger swipe operation) when the first gesture is a pinch operation. It is remembered.

  Here, consider a case where the gesture detection unit 101 detects a pinch operation (first gesture) and a two-finger swipe operation (second gesture) by simultaneous touch input. At this time, the operation error determination unit 103 determines whether or not the two-finger swipe operation as the second gesture is due to a user operation error. When it is determined that the two-finger swipe operation is due to a user's operation error, the priority determination unit 104 determines the priority of the two-finger swipe shown in the priority 1054 when the first gesture is the pinch operation For example, “1” is subtracted from the value “−7” (see FIG. 6B), and the calculated value is stored in the priority storage unit 105. If it is not determined that the two-finger swipe operation is due to a user operation error, the priority determination unit 104 determines the priority of the two-finger swipe shown in the priority 1054 when the first gesture is a pinch operation. For example, “1” is added to the degree value “−7”, and the calculated value is stored in the priority storage unit 105.

  FIG. 8 is a flowchart of an operation flow of the touch panel device according to the third embodiment. The description of the same processing as the processing shown in the flowcharts of FIGS. 4 and 5 is omitted.

  In the third embodiment, when it is determined that the second gesture is caused by a user's operation error (YES in step S58), priority determination unit 104 stores the first gesture stored in priority storage unit 105. The priority of the second gesture with respect to is lowered (step S59).

  When it is determined that the second gesture is not due to a user's operation error (NO in step S58), the priority determination unit 104 performs the second gesture for the first gesture stored in the priority storage unit 105. Is increased (step S60).

  In the third embodiment, the information processing unit 106 refers to the priority of the second gesture with respect to the first gesture stored in the priority storage unit 105, and the priority of the second gesture is determined in advance. It is determined whether or not the value is equal to or greater than a predetermined value (step S55).

  Whether or not the second gesture is due to a user's operation error depends on the type of the first gesture. For example, when the first gesture is a pinch operation and the second gesture is a rotation operation, the rotation operation is relatively likely to be a user operation error. This is because the pinch operation and the rotation operation are relatively similar, and the user may input unintentionally.

  On the other hand, according to the touch panel device according to the third embodiment, the priority determination unit 104 prioritizes the second gesture detected during the detection of the first gesture for each type of the first gesture. Determine the degree. For this reason, the touch panel device according to the modified example 1 can further suppress execution of information processing that is not intended by the user based on an operation error of the user.

  The present invention is not limited to the configuration of the above embodiment, and various modifications can be made.

<Modification>
In the above embodiment, the information processing unit 106 determines whether or not to execute the information processing corresponding to the second gesture by comparing the priority of the second gesture with a predetermined value. However, the present invention is not necessarily limited to this case.

  The information processing unit 106 may determine whether to perform information processing corresponding to the second gesture by comparing the priority of the first gesture and the priority of the second gesture. That is, in this modification, the priority of the first gesture is used as a predetermined value that determines whether or not to perform information processing corresponding to the second gesture.

  The information processing unit 106 executes information processing corresponding to the first gesture and the second gesture when the priority of the second gesture is equal to or higher than the priority of the first gesture. In addition, when the priority of the second gesture is lower than the priority of the first gesture, the information processing unit 106 does not execute the information processing corresponding to the second gesture and does not perform the information processing corresponding to the first gesture. Perform processing only.
