  By the way, in the conventional mechanical key device, there are unevenness, a click feeling and a stroke feeling, so there are few key press mistakes. On the other hand, since there is no click feeling on the touch panel, erroneous operations are likely to occur. Further, in a portable electronic device, since the display unit is small, the selection range for one selection item is narrow. Therefore, when the user operates with a finger, it is difficult to touch the selection range accurately, and thus an erroneous operation is likely to occur.

  SUMMARY An advantage of some aspects of the invention is that it provides an electronic device that can suppress erroneous operations when an item is selected using a touch panel.

  An electronic apparatus according to the present invention includes a display unit that displays a menu including a plurality of selection items, a touch panel that is disposed at a position that overlaps the selection items, and that detects a pressing position corresponding to the selection items, and the touch panel. Based on the detected pressing position, a selection item selected from the menu is determined, an execution unit that executes a predetermined process according to the selection item, and a history of the process executed by the execution unit When a combination of a selection item selected in error and a selection item correctly selected thereafter is detected from the storage unit to be stored and the processing history stored in the storage unit, the pressing position and the execution unit are detected. And a control unit that changes the correspondence relationship with the selection item determined by.

  Moreover, it is preferable that the said control part changes the said correspondence, when the said combination is detected more frequently than predetermined.

  Moreover, it is preferable that the said control part changes the display of the selection item in the said display part according to the said changed correspondence.

  Moreover, it is preferable that the said control part expands the area | region of the press position corresponding to the said selection item selected correctly.

  In addition, the control unit has enlarged the area of the pressing position corresponding to the correctly selected selection item based on the selection frequency for each selection item calculated from the processing history stored in the storage unit. Accordingly, it is preferable to determine a selection item for reducing the area of the pressed position.

  Moreover, it is preferable that the said control part replaces the area | region of the press position corresponding to the said selection item selected correctly, and the area | region of the press position corresponding to the said selection item selected accidentally.

  Moreover, it is preferable that the said control part detects the said combination based on the space | interval of the time when two selection items were each selected.

  ADVANTAGE OF THE INVENTION According to this invention, an erroneous operation can be suppressed at the time of the item selection by a touch panel.

[First Embodiment]
The first embodiment of the present invention will be described below.

  FIG. 1 is an external perspective view of a mobile phone 1 (electronic device) according to the present embodiment. FIG. 1 shows a so-called foldable mobile phone, but the mobile phone according to the present invention is not limited to this. For example, a sliding type in which one casing is slid in one direction from a state in which both casings are overlapped, or a rotary type in which one casing is rotated around an axis along the overlapping direction ( Turn type), or a type (straight type) in which the operation unit and the display unit are arranged in one housing and does not have a connecting unit.

  The mobile phone 1 includes an operation unit side body 2 and a display unit side body 3. The operation unit side body 2 includes a key input unit 11 and a microphone 12 to which a voice uttered by a user of the mobile phone 1 is input on the surface unit 10. The key input unit 11 includes a function setting operation button 13 for operating various functions such as various setting functions, a phone book function, and a mail function, and an input operation button 14 for inputting a telephone number and mail characters. And a determination operation button 15 for performing determination and scrolling in various operations.

  The display unit side body 3 includes a display unit 21 for displaying various types of information on the surface unit 20 and a receiver 22 for outputting the voice of the other party of the call. Furthermore, a touch panel 23 that can transmit an image displayed on the display unit 21 and receives an operation input by pressing is disposed on the surface unit 20 so as to overlap the display unit 21.

  Further, the upper end portion of the operation unit side body 2 and the lower end portion of the display unit side body 3 are connected via a hinge mechanism 4. In addition, the mobile phone 1 relatively rotates the operation unit side body 2 and the display unit side body 3 which are connected via the hinge mechanism 4, so that the operation unit side body 2 and the display unit side body 3 are rotated. The body 3 can be in an open state (open state), or the operation unit side body 2 and the display unit side body 3 can be folded (folded state).

  FIG. 2 is a block diagram showing functions of the mobile phone 1 according to the present embodiment. The mobile phone 1 includes a CPU 30 (execution unit, control unit), a memory 31 (storage unit), a display unit 21, and a touch panel 23. In FIG. 2, only functional blocks according to the description of the present embodiment are shown, and other functions that are naturally provided as a mobile phone, such as communication control and voice control, are omitted.

  The CPU 30 controls the entire mobile phone 1, and performs predetermined control on the display unit 21, the touch panel 23, the memory 31, and the like, for example. Further, the CPU 30 receives operation inputs from the key input unit 11 (FIG. 1), the touch panel 23, and the like, and executes various processes. Then, the CPU 30 controls the memory 31 to read various programs and data and write data when executing processing.

  The memory 31 includes, for example, a working memory and is used for arithmetic processing by the CPU 30. In addition to various control programs executed by the CPU 30, for example, an operation history table (FIG. 4) described later and an erroneous operation occurrence history table (FIG. 5), which are referred to and updated during processing of the program, are stored. . Note that the memory 31 may also serve as a removable external memory.

  The display unit 21 performs predetermined image processing according to the control of the CPU 30. Then, the processed image data is stored in the frame memory and output to the screen at a predetermined timing. In the present embodiment, the display unit 21 displays a menu including a plurality of selection items adjacent to each other.

  The touch panel 23 is a sensor that detects a position touched (pressed) by a user's finger or the like. CPU30 receives the detection result by the touch panel 23, and performs various processes by making the detection result into various operation inputs. Note that the touch panel 23 can use an existing sensor such as a capacitance method or a resistance film method.

  Hereinafter, details of processing contents performed by the CPU 30 in accordance with an operation input to the touch panel 23 will be described.

  FIG. 3 is a diagram illustrating menu display on the display unit 21 according to the present embodiment and selection ranges on the touch panel 23 corresponding to a plurality of selection items constituting the menu.

  The display unit 21 displays a menu in which icons for starting nine types of applications (applications A to I) are arranged. And the area | region (selection range) of the press position in the touch panel 23 corresponding to each icon of this menu is set.

  FIG. 4 is a diagram showing an operation history table stored in the memory 31 according to the present embodiment. In the operation history table, the contents of the operation input from the user are stored in association with the operation time. In the example of FIG. 4, for example, the application A is activated by operating the touch panel 23 at time T <b> 1, and a cancel operation for ending the application A is performed at time T <b> 2. Subsequently, the application B is activated by the operation of the touch panel 23 at time T3, and the operation 1 and the operation 2 are continued.

  Here, the CPU 30 refers to the operation history table (FIG. 4) and calculates a time interval between two application activations (for example, times T1 and T3) sandwiching a cancel operation (for example, time T2). When the time interval (T3-T1) is equal to or less than the predetermined threshold Tm, it is determined that the operation at time T1 is an erroneous operation and the operation at time T3 is a correct operation. Note that instead of the cancel operation, the same determination may be made by comparing the time interval between two application activations across the end operation for terminating the activation of the application A and the threshold value Tm.

  FIG. 5 is a diagram illustrating an erroneous operation occurrence history table stored in the memory 31 according to the present embodiment. In the erroneous operation occurrence history table, combinations of erroneous operations detected by the CPU 30 and correct operations are stored together with the number of occurrences. For example, in the example of FIG. 5, the number of occurrences of a combination of the application A and the correct operation is the application B (when the activation of the application A is canceled and the application B is activated immediately) is C1.

  Although the operation history table (FIG. 4) and the erroneous operation occurrence history table (FIG. 5) are both stored in the memory 31, they are not limited to this. The operation history table (FIG. 4) may be stored in a volatile storage device because it is sufficient that an operation history within a predetermined time until the present time is stored after the mobile phone 1 is activated. On the other hand, the erroneous operation occurrence history table (FIG. 5) is stored in a nonvolatile storage device because it is necessary to learn the user operation by storing the cumulative number of occurrences from the past.

  FIG. 6 is a diagram illustrating a state in which the correspondence relationship between the selection range and the menu icon on the touch panel 23 according to the present embodiment is changed.

  When the number of occurrences C1 (erroneous operation: app A, correct operation: app B) in the erroneous operation occurrence history table (FIG. 5) exceeds a predetermined number, the CPU 30 expands the selection range of the app B on the touch panel 23, and Reduce the selection. Thereby, it can suppress that a user starts the application A mistakenly with starting of the application B, and the improvement of operativity can be anticipated.

  FIG. 7 is a flowchart showing processing of the CPU 30 according to the present embodiment. This process is executed in response to a user operation input.

  In step S1, the CPU 30 determines whether or not the operation input by the user is an application cancel operation. If this determination is YES, the process proceeds to step S2, and if the determination is NO, the process proceeds to step S5.

  In step S2, the CPU 30 determines whether or not a time (for example, T2-T1 in FIG. 4) from the application activation performed immediately before the cancel operation to the cancel operation is within a predetermined threshold Tn. . If this determination is YES, it indicates that the application has been canceled within a short period of time, and the process proceeds to step S3. On the other hand, if this determination is NO, it indicates that the application has been intended to start, and the process moves to step S11.

  In step S3, the CPU 30 turns on a cancel operation flag indicating that the cancel operation has been performed immediately after the application is started.

  In step S4, the CPU 30 stores the application activation immediately before the cancel operation (for example, the application A activation at time T1 in FIG. 4) as an erroneous operation candidate.

  In step S5, the CPU 30 determines whether or not the operation input by the user is an application activation operation. If this determination is YES, the process proceeds to step S6. If the determination is NO, the process proceeds to step S11 because the input is not related to the erroneous operation determination.

  In step S6, the CPU 30 determines whether or not the cancel operation flag is turned on in step S3. If this determination is YES, since the application activation operation has been performed immediately after the cancel operation, the process proceeds to step S7. On the other hand, if the determination is NO, it is not immediately after the cancel operation, and the process proceeds to step S11.

  In step S7, the CPU 30 determines the time (for example, T3-T1 in FIG. 4) from the erroneous operation candidate (app A) stored in step S4 until the application (for example, app B in FIG. 4) is activated in step S5. Is within a predetermined threshold Tm. When this determination is YES, since the application is switched to a different application with a cancel operation in a short time, the process proceeds to step S8. On the other hand, if this determination is NO, it is not application switching due to an erroneous operation, and the process moves to step S11.

  In step S8, the CPU 30 determines that the two application activations with the cancel operation sandwiched by the erroneous operation are switched, and the application before cancellation (application A) is erroneously operated and the application after cancellation (application B) is determined as the normal operation. Then, registration into the erroneous operation occurrence history table (FIG. 5) or update of the number of occurrences is performed.

  In step S9, the CPU 30 determines whether or not the number of occurrences stored in the erroneous operation occurrence history table (FIG. 5) exceeds a specified number. If this determination is YES, it is determined that erroneous operations frequently occur, and the process proceeds to step S10. On the other hand, if this determination is NO, it is determined that the frequency is low, and the routine goes to Step S11.

  In step S10, the CPU 30 changes the menu configuration in order to suppress erroneous operations determined to occur frequently in step S9. That is, as illustrated in FIG. 6, the CPU 30 reduces the selection range of the erroneous operation (application A) on the touch panel 23 and expands the selection range of the correct operation (application B).

  In step S11, the CPU 30 updates the operation history table (FIG. 4) based on the user operation input and time.

  According to the present embodiment, it is possible to reduce an erroneous operation at the time of item selection by the touch panel by expanding the selection range of the correct operation. In addition, since the menu configuration is changed when an erroneous operation is detected at a frequency more than a predetermined frequency, it is possible to suppress deterioration in usability due to a change in the menu configuration due to a slight erroneous operation or erroneous detection. Furthermore, the detection accuracy of an erroneous operation is improved by using the time interval for starting the application as a determination condition.

[Second Embodiment]
Hereinafter, a second embodiment of the present invention will be described. In the present embodiment, the process of changing the menu configuration (step S10 in FIG. 7) in the first embodiment is different, and the CPU 30 changes the icon display on the display unit 21 in accordance with the change of the selection range on the touch panel 23. .

  FIG. 8 is a diagram showing how the selection range on the touch panel 23 and the menu icon display are changed when an erroneous operation icon and a correct operation icon are adjacent to each other in the present embodiment.

  When the number of occurrences C1 (erroneous operation: app A, correct operation: app B) in the erroneous operation occurrence history table (FIG. 5) exceeds a predetermined number, the CPU 30 expands the selection range of the app B on the touch panel 23, and Reduce the selection. Furthermore, the CPU 30 enlarges the icon of the app B and makes the icon of the app A smaller in the menu display on the display unit 21. Thereby, the menu display and the selection range on the touch panel 23 are matched.

  FIG. 9 is a diagram showing how the selection range on the touch panel 23 and the menu icon display are changed in the present embodiment.

  When the number of occurrences C3 (erroneous operation: app A, correct operation: app I) in the erroneous operation occurrence history table (FIG. 5) exceeds a predetermined number, the CPU 30 selects the app A selection range and the app I selection range on the touch panel 23. And replace. Further, the CPU 30 switches the display of the icon of the application A and the icon of the application I in the menu display on the display unit 21. Thereby, the menu display and the selection range on the touch panel 23 are matched.

  According to this embodiment, since the selection range of the touch panel 23 and the menu display match, it is possible to prevent confusion due to a difference in appearance and reaction area. In addition, there is a possibility that pressing errors between selection items that are not adjacent to each other can be reduced.

[Third Embodiment]
Hereinafter, a third embodiment of the present invention will be described. In the present embodiment, the process of changing the menu configuration (step S10 in FIG. 7) in the first embodiment is different. In addition to the operation history table (FIG. 4) and the erroneous operation occurrence history table (FIG. 5), the memory 31 stores an activation number table. Then, the CPU 30 adjusts the selection range on the touch panel 23 based on the frequency of application activation.

  FIG. 10 is a diagram showing a startup number table stored in the memory 31 according to the present embodiment. The activation count table stores the activation count for each application type (applications A to I). The number of activations may be the number of integrations from the start of use or the number of times in a predetermined period up to the present.

  FIG. 11 is a diagram showing how the selection range and menu icon display on the touch panel 23 according to the present embodiment are changed.

  When the number of occurrences C1 (erroneous operation: app A, correct operation: app B) in the erroneous operation occurrence history table (FIG. 5) exceeds a predetermined number, the CPU 30 expands the selection range of the app B on the touch panel 23. At this time, the CPU 30 refers to the activation count table (FIG. 10) and acquires the activation count of the applications (application A and application C) adjacent to the application B. In the example of FIG. 10, since the number of activations of the application C is smaller than that of the application A, the selection range for the application C is reduced so that the activation of the application A is not difficult.

  Here, the number of activations of application A is larger than that of application B and application C. Therefore, as shown in FIG. 11, the CPU 30 may expand the selection range of the application A in order to prevent the selection error of the application A.

  In the present embodiment, in a combination of an erroneous operation (app A) and a correct operation (app B), for example, as shown in FIG. 11, the boundary of the selection range may not be adjusted in a direction (approaching app A) to suppress the erroneous operation. is there. Therefore, it is preferable to change the icon display of the application on the display unit 21 according to the selection range on the touch panel 23. As a result, the icon display and the selection range of the application (application B) that is likely to cause an erroneous operation are increased, and the selection operation is facilitated.

  According to the present embodiment, since the selection range on the touch panel 23 is adjusted based on the frequency of application activation, it is possible to suppress erroneous operations and maintain operability.

  As mentioned above, although embodiment of this invention was described, this invention is not restricted to embodiment mentioned above. The effects described in the embodiments of the present invention are only the most preferable effects resulting from the present invention, and the effects of the present invention are limited to those described in the embodiments of the present invention. is not.

  For example, the CPU 30 can further prompt the user to perform a correct operation as described below by detecting a combination of an erroneous operation and a correct operation.

  FIG. 12 is a diagram illustrating a state in which an erroneous operation is led to a correct operation. If the application A is activated but a cancel operation is performed immediately (for example, within a predetermined time), the CPU 30 determines that the application A is an erroneous operation.

  Here, the CPU 30 refers to the erroneous operation occurrence history table (FIG. 5), and when the number of occurrences C1 related to the combination of “erroneous operation: app A, correct operation: app B” is large, it leads to the correct operation app B. Light up the B icon. Further, the CPU 30 may not accept selection of another icon. Then, when a certain time elapses, the CPU 30 returns to the initial state.

  Thereby, the user can select a correct application correctly. In addition, even if it is not an erroneous operation determined by the CPU 30, an arbitrary operation input can be performed after a certain time.

  In the above embodiment, the mobile phone 1 has been described as an example of the electronic device, but the present invention is not limited to this. For example, the present invention can be applied to various electronic devices such as a PHS (Personal Handyphone System), a PDA (Personal Digital Assistant), a portable navigation device, and a PC (Personal Computer).
