  In another aspect, the operation control method is an operation control method executed by an electronic device including a display unit, a detection unit that detects contact with the display unit, and a vibration unit that vibrates the detection unit. In the first state in which a predetermined process based on an operation by contact with the display unit is not performed, the detection unit detects the contact with the display unit, and the detection unit detects the contact with the detection unit. In the first state, the vibration unit vibrates the detection unit, and when the detection unit detects contact with a predetermined position on the display unit, the first unit causes the display unit to Switching to a second state in which a predetermined process based on an operation by contact is performed.

  In another aspect, an operation control program is provided in an electronic device including a display unit, a detection unit that detects contact with the display unit, and a vibration unit that vibrates the detection unit. In a first state in which a predetermined process based on the above is not performed, the detection unit detects a contact with the display unit, and the vibration unit vibrates the detection unit based on the contact detected by the detection unit. And in the first state, when the detection unit detects a contact with a predetermined position on the display unit, a predetermined process based on an operation by the contact with the display unit is performed from the first state.

  The RAM 11 is used as a storage area for temporarily storing instructions of a program executed by the control unit 10, data referred to by the control unit 10, calculation results of the control unit 10, and the like.

  Next, a function for causing the user to recognize the contact position will be described with reference to FIG. FIG. 3 is a diagram for explaining a function for causing a user to recognize a contact position.

  As shown in FIG. 3, the mobile phone terminal 1 in operation takes either the first state or the second state. The first state is a state for allowing the user to recognize the contact position, and the second state is a state for executing various processes (predetermined processes) in accordance with the user's contact operation. .

  In step S <b> 11 of FIG. 3, the mobile phone terminal 1 is in the first state with the standard screen displayed on the touch panel 2. The standard screen is a screen in a state waiting for various functions such as a call function and an e-mail function. In other words, the standard screen is a screen before switching to a screen corresponding to various functions provided by the mobile phone terminal 1. Note that the standard screen may be called a standby screen, an initial screen, a desktop screen, a home screen, or wallpaper, for example.

  In the first state, the supply of power to the display unit 2B of the touch panel 2 may be stopped and the display unit 2B may be turned off. However, even when the supply of power to the display unit 2B is stopped, the supply of power to the touch sensor 2A is continued, and the touch sensor 2A is kept in a state where the touch operation can be detected.

  The mobile phone terminal 1 displays a plurality of icons I1 on the standard screen. The icons I1 are image objects that are associated with specific functions, and are arranged at equal intervals. When the mobile phone terminal 1 is in the second state, when the touch operation in the display area of any icon I1 is detected by the touch panel 2, the mobile phone terminal 1 changes to the icon I1 in which the touch operation is detected. The corresponding function (predetermined process) is executed.

  On the other hand, when the mobile phone terminal 1 is in the first state, the icon I1 is used as a clue to make the user recognize the contact position. Specifically, when the mobile phone terminal 1 is in the first state, when the touch operation in the display area of any icon I1 is detected by the touch panel 2, the mobile phone terminal 1 The touch panel 2 is vibrated. The intensity and pattern of the vibration are changed according to the icon I1 in which the contact operation is detected. For this reason, the user can recognize to which icon I1 he / she performed the contact operation based on the intensity or pattern of vibration generated in response to the contact operation. In the first state, since predetermined processing based on an operation by contact is not performed, even if a contact operation on the icon I1 is detected, only a vibration is generated and a function corresponding to the icon I1 is not executed.

  Further, when the mobile phone terminal 1 is in the first state, the reference position B1 is set at a predetermined position on the touch panel 2. The user knows where the reference position B1 is on the touch panel 2 (for example, the center on the touch panel 2), and remembers in advance the relative position of each object such as the icon I1 viewed from the reference position B1. Yes. The mobile phone terminal 1 transitions to the second state when the touch panel 2 detects a position where the reference position B1 is set or a contact operation within the display area of the icon I1 including the reference position B1.

  That is, after finding the reference position B1 based on the vibration intensity and pattern, the user performs a contact operation on an arbitrary object based on a known relative position, and activates a function corresponding to the object. be able to.

  In the example shown in FIG. 3, the reference position B <b> 1 is provided near the center of the touch panel 2. Since the vicinity of the center is relatively close to any position on the touch panel 2, it is suitable as a position for setting a clue for performing a contact operation on an arbitrary position on the touch panel 2. Note that the position where the reference position B1 is set may be changed according to the designation of the user or the arrangement of objects such as buttons and icons for receiving input on the screen displayed in the first state.

  In step S <b> 12 illustrated in FIG. 3, the user performs a contact operation at a position P <b> 1 on the touch panel 2. The position P1 is included in the display area of the icon I1 displayed on the upper right of the touch panel 2. For this reason, when the touch panel 2 detects the touch operation at the position P1, the mobile phone terminal 1 vibrates the vibration unit 4 with the intensity and pattern corresponding to the icon I1 including the position P1. The correspondence between the object such as the icon I1 and the intensity and pattern of the vibration is defined in the vibration definition data 9D.

  FIG. 4 is a diagram illustrating an example of the vibration definition data 9D. The vibration definition data 9D shown in FIG. 4 has items of display position, intensity, and pattern, and data is registered for each object. The display position is a position where the object is displayed. The strength is the strength of vibration corresponding to the object, and the larger the value, the stronger the strength. The pattern is a vibration pattern corresponding to the object, and a combination of a black circle indicating that vibration is generated for a certain period and a white circle indicating that generation of vibration for a certain period is suppressed is set.

  In the vibration definition data 9D shown in FIG. 4, at least one of the intensity and the pattern is different for each object. In this way, by setting the vibration definition data 9D, the user can identify the object that is the target of the contact operation based on the vibration intensity and pattern. The vibration definition data 9D may be set in advance or may be set individually by the user.

  FIG. 5 is a diagram illustrating another example of the vibration definition data 9D. The vibration definition data 9D shown in FIG. 5 has items of distance, intensity, and pattern from the reference position, and data is registered for each distance from the reference position. The distance from the reference position is a value indicating the distance of the object from the reference position B1. The distance from the reference position is 0 when the reference position B1 exists in the display area of the object, and becomes a larger value as the object is farther from the reference position B1. The intensity is the intensity of vibration corresponding to the object. The pattern is a vibration pattern corresponding to the object.

  The vibration definition data 9D shown in FIG. 5 is set such that the farther the object is from the reference position B1, the weaker the vibration intensity and the shorter the vibration time in one pattern. In this way, by changing the vibration intensity and pattern according to a certain rule in accordance with the distance from the reference position B1, the user does not have to remember the vibration intensity and pattern corresponding to each object. The position B1 can be found.

  In step S13, the user roughly searches the reference position B1 based on the vibration intensity and pattern of the touch panel 2, and performs a contact operation at a position P2 in the vicinity of the reference position B1. The position P2 is included in the display area of the icon I1 displayed at the center of the touch panel 2, and the reference position B1 exists in the same display area. As described above, when the touch panel 2 detects a contact operation in the same display area as the reference position B1, the mobile phone terminal 1 vibrates the vibration unit 4 with the intensity and pattern corresponding to the icon I1 displayed in the area. Then, the process proceeds to the second state as step S14.

  At this time, the user can know that he / she performed the touch operation on the icon I1 including the reference position B1 and that the mobile phone terminal 1 has transitioned to the second state. Further, the user does not visually check where each icon I1 is arranged based on the knowledge about the relative position between the reference position B1 and each icon I1 and the intensity and pattern of the detected vibration. Can be estimated almost exactly.

  In addition, it is preferable to make the intensity | strength and pattern of the vibration to generate | occur | produce clearly differ from another scene so that a user can recognize a state transition reliably from the 1st state to the 2nd state. Further, in order to enable the user to reliably recognize the state transition, other notification means such as a notification sound output from the speaker 7 may be used in combination.

  In step S <b> 15 shown in FIG. 3, the user performs a contact operation at a position P <b> 3 on the touch panel 2. The position P3 is included in the display area of the icon I1 displayed on the upper right side of the touch panel 2 similarly to the position P1. Since the mobile phone terminal 1 has transitioned to the second state, when the touch panel 2 detects a touch operation at the position P3, the mobile phone terminal 1 executes a function associated with the icon I1 including the position P3. At this time, the mobile phone terminal 1 causes the vibration unit 4 to vibrate to indicate that the function has been executed. The intensity and pattern of vibration at this time may be the same as or different from the case where the contact operation at the position P3 is detected in the first state.

  For example, it is assumed that the function associated with the icon I1 including the position P3 is a function for displaying a list of received mails. In this case, the cellular phone terminal 1 displays the received mail list screen on the touch panel 2 in accordance with the contact operation at the position P3 as in step S16.

  Thus, the cellular phone terminal 1 takes the first state in addition to the second state in which the function associated with the object is activated in response to the contact operation on the object displayed on the touch panel 2. Let the user recognize the contact position of the contact operation. That is, the mobile phone terminal 1 is configured so that the user can easily activate a desired function by recognizing the contact position.

  Note that the icon I1 including the reference position B1 is treated as a special region for the transition from the first state to the second state in the first state, but in the second state, It is handled in the same manner as the icon I1. That is, in the second state, the icon I1 including the reference position B1 is used as an area for starting the associated function. Further, the mobile phone terminal 1 generates vibration only for the contact operation with respect to the icon I1 including the reference position B1 among the icons I1 displayed on the touch panel, and with respect to the contact operation with respect to other icons I1. Thus, vibrations may not be generated.

  Next, a control processing procedure executed by the mobile phone terminal 1 in the first state and the second state will be described with reference to FIGS. 6 and 7. FIG. 6 is a flowchart showing a processing procedure of contact operation control in the first state. FIG. 7 is a flowchart showing a processing procedure of contact operation control in the second state. The processing procedure shown in FIGS. 6 and 7 is realized by the control unit 10 executing the operation control program 9C.

  As shown in FIG. 6, when the mobile phone terminal 1 is in the first state, the control unit 10 determines whether a touch operation on the display unit 2B has been detected as step S101. When the contact operation is not detected (No at Step S101), the control unit 10 re-executes the determination at Step S101.

  When a contact operation is detected (step S101, Yes), the control part 10 determines whether the position where the contact operation was performed is in the display area of objects, such as an icon, as step S102. When the position where the contact operation is performed is not within the display area of the object (No at Step S102), the control unit 10 re-executes Step S101 and the subsequent steps.

  When the position where the contact operation is performed is within the display area of the object (step S102, Yes), the control unit 10 acquires the vibration intensity and pattern corresponding to the object from the vibration definition data 9D as step S103. . In step S104, the control unit 10 causes the vibration unit 4 to vibrate the touch sensor 2A with the acquired intensity and pattern.

  Subsequently, in step S105, the control unit 10 determines whether or not the reference position B1 is within the display area of the object on which the contact operation has been performed. When there is no reference position B1 (No at Step S105), the control unit 10 re-executes Step S101 and the subsequent steps. On the other hand, when there exists reference position B1 (step S105, Yes), the control part 10 switches the mobile telephone terminal 1 to a 2nd state as step S106.

  As shown in FIG. 7, when the mobile phone terminal 1 is in the second state, the control unit 10 determines whether a touch operation on the display unit 2B has been detected as step S201. When a contact operation is detected (step S201, Yes), the control part 10 determines whether the position where the contact operation was performed is in the display area of objects, such as an icon, as step S202. When the position where the contact operation is performed is not within the display area of the object (No at Step S202), the control unit 10 re-executes Step S201 and the subsequent steps.

  When the position where the contact operation is performed is within the display area of the object (step S202, Yes), the control unit 10 acquires the vibration intensity and pattern corresponding to the object from the vibration definition data 9D as step S203. . Then, in step S204, the control unit 10 causes the vibration unit 4 to vibrate the touch sensor 2A with the acquired intensity and pattern. Further, the control unit 10 activates a function associated with the object in step S205. And the control part 10 performs again after step S201.

  When the contact operation is not detected in step S201 (step S201, No), the control unit 10 determines whether or not the state transition to the first state is performed as step S206. The state transition to the first state is performed, for example, when a contact operation is not detected for a predetermined period or more, or when a predetermined operation is detected by the input unit 3. When the state transition is not performed (No at Step S206), the control unit 10 re-executes Step S201 and the subsequent steps. On the other hand, when the state transition is performed (Yes in Step S206), the control unit 10 switches the mobile phone terminal 1 to the first state as Step S207.

  As described above, the cellular phone terminal 1 according to the present embodiment is configured to vibrate the touch panel 2 with the strength and pattern according to the contact position when the contact operation is received in the first state. The user can be made to recognize the contact position.

  In addition, the aspect of this invention shown by said embodiment can be arbitrarily changed in the range which does not deviate from the summary of this invention. For example, in the above embodiment, an example in which the present invention is applied to an electronic device having the touch panel 2 as a display unit has been described. However, the present invention is applicable to an electronic device in which the display unit 2B and the touch sensor 2A are not superimposed. It can also be applied. In this case, the present invention is used to make the user recognize at which position on the touch sensor 2A the contact operation is performed.

  In the above embodiment, the control unit 10 activates the function associated with the object when the position where the contact operation is performed is within the display area of the object in the second state. The invention vibrates the touch panel 2 with the intensity and pattern of vibration corresponding to the object in the first state when the position where the contact operation is performed is within the display area of the object in the first state. And a function associated with the object may be activated.

  The reference position of the present invention may be the center position of the touch panel 2 (touch sensor 2A).

  In the above embodiment, the standard screen is displayed on the touch panel 2 in the first state. However, the screen displayed in the first state is not limited to the standard screen. When a screen other than the standard screen is displayed on the touch panel 2 in the first state, when a touch operation on an object such as a button to which some function is assigned is detected, vibration is generated according to the object. That's fine. Further, the intensity and pattern of vibration may be set for each screen.

  For example, when a virtual keyboard is displayed on the touch panel 2 in the first state, vibration may be generated in accordance with the button when a touch operation on each button on the virtual keyboard is detected. An example in which a virtual keyboard is displayed will be described with reference to FIGS. 10 and 11.

  FIG. 10 is a diagram illustrating an example in which the virtual keyboard 21 having the QWERTY layout is displayed on the touch panel 2. As described above, when the QWERTY virtual keyboard 21 is displayed, in the first state, buttons corresponding to characters such as “A” and “B” and buttons corresponding to function keys such as “BS” are displayed. When a contact operation is detected, vibration may be generated according to the button. When the QWERTY virtual keyboard 21 is displayed, the reference position B2 is provided in the display area of the button corresponding to “F”, and the reference position B3 is provided in the display area of the button corresponding to “J”. Thus, it is preferable to provide a reference position in the button display area corresponding to the home position of the index finger. By providing the reference position within the display area of the button corresponding to the home position of the index finger, it becomes easier to grasp the positions of the other buttons after shifting to the second state. In this case, when it is determined that the contact operation is simultaneously performed at the position in the display area of the button corresponding to “F” and the position in the display area of the button corresponding to “J”, the second state is set. You may migrate.

  FIG. 11 is a diagram showing an example in which a virtual keyboard 22 having a numeric keypad layout is displayed on the touch panel 2. As described above, when the virtual keyboard 22 with the numeric keypad is displayed, in the first state, buttons corresponding to numbers such as “1” and “2” and buttons corresponding to function keys such as “BS”. When a contact operation is detected, vibration may be generated according to the button. When the virtual keyboard 22 with the numeric keypad is displayed, it is preferable to provide the reference position B4 in the display area of the button corresponding to “5” arranged in the center among the buttons corresponding to the numbers. By providing the reference position B4 in the display area of the button arranged at the center like the button corresponding to “5”, it becomes easy to grasp the positions of the other buttons after shifting to the second state. 10 and 11, for convenience of illustration, the reference positions B2, B3, and B4 are not located in the center of the button display area, but these reference positions are located in the center of the button display area. Is preferred.

  In the above embodiment, the vibration intensity and pattern are changed for each object in the first state, but the distance from the contact position to the reference position regardless of which region the contact position is included in. The intensity and pattern of vibration may be changed according to the direction. In this case, when a contact operation is detected within a predetermined distance from the reference position, the state may be changed to the second state.

  Moreover, when the pressing force (pressing) of the contact operation with respect to the touch panel 2 can be detected by disposing a piezoelectric element, a strain gauge sensor, or the like on the touch panel 2 (the touch panel 2 (detecting unit) detects the pressing force). If the contact operation is detected in the first state, vibration is not generated if the pressing force of the contact operation (data value such as voltage value and resistance value based on the press) is smaller than a threshold value. It is good. The operation in this case will be described with reference to FIG. FIG. 8 is a flowchart showing a modification of the processing procedure of the contact operation control in the first state.

  As shown in FIG. 8, when the mobile phone terminal 1 is in the first state, the control unit 10 determines whether a touch operation on the display unit 2B has been detected as step S301. When the contact operation is not detected (No at Step S301), the control unit 10 re-executes the determination at Step S301.

  When a contact operation is detected (step S301, Yes), the control part 10 determines whether the position where the contact operation was performed is in the display area of objects, such as an icon, as step S302. When the position where the contact operation is performed is not within the display area of the object (No at Step S302), the control unit 10 re-executes Step S301 and the subsequent steps.

  When the position where the contact operation is performed is within the display area of the object (step S302, Yes), the control unit 10 determines whether the pressing force of the contact operation is equal to or greater than a threshold value as step S303. When the pressing force of the contact operation is not equal to or greater than the threshold value (No at Step S303), the control unit 10 re-executes Step S301 and the subsequent steps.

  When the pressing force of the contact operation is equal to or greater than the threshold (Yes at Step S303), the control unit 10 acquires the vibration intensity and pattern corresponding to the object from the vibration definition data 9D as Step S304. Then, in step S305, the control unit 10 causes the vibration unit 4 to vibrate the touch sensor 2A with the acquired intensity and pattern.

  Subsequently, in step S306, the control unit 10 determines whether or not the reference position B1 is within the display area of the object on which the contact operation has been performed. When there is no reference position B1 (No at Step S306), the control unit 10 re-executes Step S301 and the subsequent steps. On the other hand, when there exists reference position B1 (step S306, Yes), the control part 10 switches the mobile telephone terminal 1 to a 2nd state as step S307.

  Thus, by applying the pressing force of the contact operation to the condition, the mobile phone terminal 1 can be prevented from transitioning from the first state to the second state due to an unexpected contact.

  Further, in the second state, the user may activate the function corresponding to the contact position after confirming where the contact position is. The operation in this case will be described with reference to FIG. FIG. 9 is a flowchart showing a modification of the processing procedure of the contact operation control in the second state.

  As shown in FIG. 9, when the mobile phone terminal 1 is in the second state, the control unit 10 determines whether a touch operation on the display unit 2B has been detected as step S401. When a contact operation is detected (step S401, Yes), the control part 10 determines whether the position where the contact operation was performed is in the display area of objects, such as an icon, as step S402. When the position where the contact operation is performed is not within the object display area (No at Step S402), the control unit 10 re-executes Step S401 and the subsequent steps.

  When the position where the contact operation is performed is within the display area of the object (step S402, Yes), the control unit 10 determines whether the detected contact operation is the first operation as step S403. Here, the first operation is an operation performed to confirm the contact position. The first operation is, for example, a single tap operation in which a tap operation is performed only once within a predetermined time.

  When the detected contact operation is the first operation (step S403, Yes), the control unit 10 acquires the vibration intensity and pattern corresponding to the object including the contact position from the vibration definition data 9D as step S404. . In step S405, the control unit 10 causes the vibration unit 4 to vibrate the touch sensor 2A with the acquired intensity and pattern. Then, the control unit 10 re-executes Step S401 and the subsequent steps.

  When the detected contact operation is not the first operation (No at Step S403), the control unit 10 determines whether the detected contact operation is the second operation as Step S406. Here, the second operation is an operation performed to activate a function corresponding to the contact position. The second operation is, for example, a double tap operation in which the tap operation is performed twice within a predetermined time.

  When the detected contact operation is the second operation (step S406, Yes), the control unit 10 activates a function associated with the object including the contact position as step S407. Then, the control unit 10 re-executes Step S401 and the subsequent steps. When the detected contact operation is not the second operation (step S406, No), the control unit 10 re-executes step S401 and subsequent steps without activating any function.

  When the contact operation is not detected in step S401 (step S401, No), the control unit 10 determines whether or not the state transition to the first state is performed as step S408. When the state transition is not performed (No at Step S408), the control unit 10 re-executes Step S401 and the subsequent steps. On the other hand, when the state transition is performed (step S408, Yes), the control unit 10 switches the mobile phone terminal 1 to the first state as step S409.

  In this way, by distinguishing between the operation that generates vibration in the second state and the operation that activates the function, the user can confirm the contact position before activating the function. Malfunctions are less likely to occur. The combination of the first operation and the first operation in the above description is an example. For example, the first operation is a long tap (long press) operation in which a finger is brought into contact with the touch panel 2 for a certain period of time. The second operation may be a single tap operation. In addition, the first operation may be an operation of bringing a finger into contact with the touch panel 2, and the second operation may be an operation of pressing the touch panel with a pressing force equal to or greater than a predetermined threshold.
