Description

  The present invention relates to a portable electronic device having a rotary dial part.

  The functions of portable electronic devices are not only capable of communicating and calling, but also can be viewed on television and radio, and are multifunctional. Here, in the portable electronic device, when other functions such as a television are not selected, a standby screen for communication / call is displayed as a top screen, and a predetermined operation is performed from the standby screen. The screen shifts to a menu selection screen for selecting another function, and the user can select another function by performing a predetermined operation on the selection menu screen. However, since a selection menu composed of a number of items is displayed on the menu selection screen, for example, such a menu selection screen feels resistance in use for a user who is unfamiliar with the operation.

  By the way, some digital cameras perform menu selection using a rotary dial. A menu for assisting shooting work such as a movie function (function for recording a moving image) and a continuous shooting function (a function for performing a plurality of still image shootings in a short time) is assigned to the rotary dial so as to be selectable (for example, , See Patent Document 1).

  Such a rotary dial is provided with an index (icon) corresponding to the function to be activated. However, when the number of functions increases, there is a problem that icons become smaller and visibility deteriorates.

In addition, in a digital camera, a technique has been proposed in which a menu assigned to a dial is displayed on a display unit in conjunction with a dial rotation operation (see, for example, Patent Document 2).

The imaging unit 17 and a light emitting unit 18 that outputs a constant amount of light are provided.

  Here, operations and functions of the rotary dial unit 41 will be described. As shown in FIG. 4, the rotary dial unit 41 is moved along a rotation axis X of the hinge mechanism 4 by a user's finger in a predetermined direction (a direction in FIG. 4 (first direction orthogonal to the rotation axis of the hinge mechanism 4). Direction) and b direction (second direction orthogonal to the rotation axis of the hinge mechanism 4)). The rotary dial unit 41 is not limited to the configuration shown in FIG. 4, and may be any configuration that can be rotated by a user's operation, and is predetermined along an axis in a direction orthogonal to the rotation axis (hinge axis) X. The structure etc. which rotate freely to a direction may be sufficient.

  In addition, the rotary dial unit 41 is provided with a plurality of indicators (corresponding to indicators and icons) I at predetermined intervals in the rotation direction. For example, as shown in FIG. 5, the index I is drawn with an image that is easy to understand for the user to be an index when selecting an application.

  Here, the operation of the rotary dial unit 41 by the user will be briefly described. The user rotates the index I corresponding to the desired application to the selected position (mark) S using the index I as a clue. The mobile phone 1 activates an application corresponding to the index I that is stationary next to the selected position S (mark). In this way, the rotary dial unit 41 enables menu selection that exhibits various functions by operating a physical rotary dial.

  Further, for example, as shown in FIG. 5, the rotary dial unit 41 is rotated by 45 ° in the a direction (315 ° in the b direction) with reference to the time of no operation (neutral (N)) by the user's rotation operation. Thus, the camera function of the imaging unit 17 is activated, and the mail function is activated by being rotated 90 ° in the a direction (270 ° in the b direction). Further, the rotation dial unit 41 is rotated 135 ° in the a direction (225 ° in the b direction) with reference to the time when there is no operation ((N)), so that the calendar function is activated, and 180 ° ( The tool menu (a menu for performing various settings relating to sound output and the like in the mobile phone 1) is activated by being rotated 180 degrees in the direction b. In addition, the rotary dial unit 41 is rotated 225 ° (135 ° in the b direction) in the a direction with reference to the time of no operation ((N)), whereby the TV function is activated, and the 270 ° ( The notepad function is activated by rotating 90 degrees in the b direction, and the address book is activated by rotating 315 degrees in the a direction (45 degrees in the b direction).

  In addition, the menu allocated according to the rotation angle of the rotary dial part 41 mentioned above is an example, Comprising: It is not limited to this. For example, a configuration in which a menu frequently used by the user himself / herself can be registered, or a desired Web address is registered, and the Web browser is selected by the rotary dial unit 41 is selected. May be configured so that the web page of the web address can be browsed. Also, the number of menus is not limited to the number (seven) described above.

  In addition, the user can directly activate various functions assigned to the rotary dial unit 41 under certain conditions by directly operating the rotary dial unit 41, via the main menu as in the past. This makes it possible to easily start a desired application.

  In the present invention, as shown in FIG. 6, when the mobile phone 1 is in the open state, the rotary dial unit 41 is rotated when the rotary dial unit 41 is operated to select a predetermined application. It has a function to animate and display on the display 21 schematically. By having such a function, the operation of the rotary dial unit 41 can be assisted by the display on the display 21, so that the operability for the user can be improved. In FIG. 6, the index I of the rotary dial unit 41 currently on the selected position S (mark) is displayed on the display 21 so as to be larger than the indices before and after that. Moreover, in Y in FIG. 6, only the rotary dial part 41 is taken out and enlarged.

  Here, a configuration for realizing the above-described function will be described. As shown in FIG. 7, the mobile phone 1 includes a display 21 that displays predetermined information, a sub-display 23 that displays predetermined information, a rotary dial unit 41 that is rotated by a user operation, an external terminal, A communication unit 60 that performs communication, a processing unit 70 that performs predetermined processing, a rechargeable battery 80 having a predetermined capacity, a power supply voltage supplied from the rechargeable battery 80 is converted into a predetermined voltage, and the converted voltage is communicated A power supply circuit unit 90 that supplies power to the unit 60, the processing unit 70, and the like, and a storage unit 100 having a table 110.

  The communication unit 60 includes a main antenna 61 that communicates with an external device using a predetermined use frequency band, and a communication processing unit 62 that performs signal processing such as modulation processing or demodulation processing.

  The main antenna 61 communicates with an external device (base station) in a predetermined use frequency band (for example, 800 MHz). In the present embodiment, the predetermined use frequency band is 800 MHz, but other frequency bands may be used. Further, the main antenna 61 may have a so-called dual band compatible type that can support a second use frequency band (for example, 2 GHz) in addition to a predetermined use frequency band. You may be comprised by the multiple band corresponding | compatible type | mold which can respond | correspond to the use frequency band or more.

  The communication processing unit 62 demodulates the signal received by the main antenna 61 and supplies the processed signal to the processing unit 70. On the other hand, the communication processing unit 62 modulates the signal supplied from the processing unit 70 and passes through the main antenna 61. To the external device (base station).

  The power supply circuit unit 90 transforms the power supply voltage supplied from the rechargeable battery 80 to a predetermined voltage value, and supplies the power supply voltage after the transformation to the communication unit 60, the processing unit 70, and the like.

  The storage unit 100 stores a large number of programs executed by the processing unit 70, parameters, various tables, and the like. Specifically, the storage unit 100 operates a large number of application programs that are activated, terminated, interrupted, and the like by the control unit 73 described later, parameters used in the plurality of applications, and a plurality of application programs. An OS (Operating System) program or the like is stored. Furthermore, a table 110 is stored that indicates the correspondence between the applications to be activated (see FIG. 5) and the correspondence between the display objects to be displayed with respect to the rotation state detected by the rotation detection unit 71. Further, the storage unit 100 updates and stores the current position of the rotary dial under the control of the control unit 73. That is, if a reference position is set as a default value in the storage unit 100, it is possible to grasp how many adjacent positions from the reference position the current rotary dial unit 41 is stationary by referring to the storage unit 100. be able to.

  The plurality of application programs include application programs for each application that the mobile phone 1 has such as a reference application, a television, a camera, and mail.

  As illustrated in FIG. 8, the processing unit 70 includes a rotation detection unit 71, a display object selection unit 72, and a control unit 73.

  The rotation detection unit 71 detects a distance from a reference position to each index as a rotation amount when the rotary dial unit 41 is rotated.

  The display object selection unit 72 refers to the table 110 of the storage unit 100, specifies an application corresponding to the rotation amount detected by the rotation detection unit 71, and selects a display object corresponding to the specified application.

  When the rotary dial unit 41 is rotated, the control unit 73 replaces the predetermined standby screen with the display object selected by the display object selection unit 72 according to the movement of the indicator that changes due to the rotation. (Display 21).

  In the present embodiment, the rotation detection unit 71 detects the amount of change in the angle of the rotary dial unit 41 as the amount of rotation. However, the present invention is not limited to this, and if the change according to the rotation of the rotary dial unit 41 can be detected. For example, a change in resistivity or the like may be detected as the rotation amount.

  With this configuration, in the present invention, as the rotary dial unit 41 rotates, the state of the rotation can be enlarged and displayed on the display 21, so that the operability by the rotary dial unit 41 is improved. Can do.

  Further, as shown in FIG. 9, the processing unit 70 activates a rotation detection unit 71 that detects that the rotary dial unit 41 is rotated and an application corresponding to the rotation state detected by the rotation detection unit 71. The control part 73 which controls to may be sufficient. Further, when the rotary dial unit 41 is rotated, the control unit 73 displays at least a display object corresponding to the index selected by the rotary dial unit 41 on the display 21 in conjunction with the rotation of the rotary dial unit 41. .

  By being configured in this way, in the present invention, for example, when the user's finger is entirely applied to the rotary dial unit 41, the index attached to the rotary dial unit 41 is hidden, Although it is difficult to select an index corresponding to a desired application, a display object corresponding to the index is displayed on the display 21 in conjunction with the movement of the rotary dial unit 41, so that visual assistance is performed. Therefore, it is easy to select an index corresponding to a desired application, and user operability can be improved.

  Further, in the configuration shown in FIG. 9, the control unit 73 has at least an index selected by the rotary dial unit 41 in a range where the rotary dial unit 41 is exposed to the outside when the rotary dial unit 41 is rotated. It is preferable to display the display objects corresponding to the indices arranged before and after the display on the display 21 in conjunction with the rotation of the rotary dial unit 41.

  With this configuration, in the present invention, an external image of the rotary dial unit 41 that is actually reflected in the user's vision is typically displayed on the display 21. Therefore, the present invention does not give the user a sense of incongruity in the operation.

  Further, the rotary dial portion 41 is rotatably attached to the same axis as the hinge axis of the hinge mechanism 4. The control unit 73 moves the display object displayed on the display unit in a direction perpendicular to the hinge axis in conjunction with the rotation of the rotary dial unit 41, that is, attached to the rotary dial unit 41. The index I is controlled to move in the same direction as the direction of rotation.

  With this configuration, in the present invention, the rotation direction of the rotary dial unit 41 and the scroll direction of the display object displayed on the display 21 are synchronized, so that the user does not feel uncomfortable in the operation.

  Finally, display control according to the present invention will be described focusing on processing by the control unit 73. When the main power supply of the mobile phone 1 is turned on, the control unit 73 first starts an OS program.

  And the control part 73 starts a reference | standard application program under management of OS program, and displays a standby screen on the display 21 based on a reference | standard application program.

  Thereafter, the control unit 73 determines the occurrence of rotation of the rotary dial unit 41 by monitoring the rotation detection unit 71. When the rotation detection unit 71 determines that rotation has occurred, the control unit 73 first confirms the currently selected position of the rotary dial unit 41 stored and updated in the storage unit 100. Further, the display object selection unit 72 refers to the table 110 and specifies a display object corresponding to the current position. The control unit 73 displays the specified display object on the display 21 instead of the standby screen. Further, the control unit 73 then receives the rotation data from the rotation detection unit 71, regards it as a change from the stored current position based on the rotation direction and the amount of movement thereof, and determines the table 110 according to the rotation operation. The display object to be displayed next is specified by the display object selection unit 72, and the specified display object is displayed on the display 21. Further, every time the detection position of the rotary dial unit 41 changes, the control unit 73 updates the storage of the storage unit 100 with the changed position as the current position.

  Next, a case where a plurality of display objects are displayed on the display 21 instead of only one will be described. As described above, when the rotation dial unit 41 rotates, the display object selection unit 72 refers to the storage unit 100 to identify the display object corresponding to the current position, and before and after the identified display object. The display objects to be registered are also specified (note that the registration order of the display objects in the table 110 needs to coincide with the correspondence with the index I of the rotary dial). When the display object is specified, the control unit 73 displays the specified display object on the display 21. Then, the control unit 73 changes the display object extracted from the table 110 in the direction corresponding to the rotation direction of the rotary dial unit 41, and changes and displays the front and rear display objects each time.

  In this case, it is preferable to display on the display all the indicators I of the rotary dial portion 41 that can be seen from the gaps in the housing. For example, in FIG. 6, due to the structure, three indicators I, “mail” and “camera” can be seen before and after the “address book”. In such a case, the control unit 73 can specify the index “address book” that is stationary at the selected position (mark) S when the current position is retrieved from the storage unit 100. Then, the control unit 73 searches the table 110 for display objects corresponding to the “address book” and display objects registered before and after the display object. As described above, since it is registered on the table 110 in association with the arrangement order of the index I, “mail” and “camera” are extracted before and after the “address book” as the display object. By the way, if it is a structure in which five indicators I can be seen, it can be realized by further searching and specifying display objects before and after and displaying them.

  Then, as these displays, the control unit 73 displays the index display object “address book” stationary at the selected position (mark) S in the center, and displays the display objects “mail” and “camera” before and after. Are displayed at the top and bottom of the “address book” display object, next to the “address book”. By doing in this way, it will be displayed on the display 21 with a sense of perspective by approximating the appearance of the index on the rotary dial unit 41, and a more intuitive operation can be supported.

  Note that the display object is preferably arranged in a direction orthogonal to the hinge axis. That is, the display object is arranged in a direction that coincides with the rotation direction of the rotary dial portion 41 that rotates about an axis that substantially coincides with the hinge axis, so that intuition can also be improved.

  Thereafter, the control unit 73 specifies whether the rotation direction of the rotary dial unit 41 is “mail” or “camera”, searches the table 110 for display objects before and after the specified display object, The display on the display 21 is updated with the animation. With such a display update method (first display update method), it is possible to perform a display with very good response.

  Alternatively, as another display update method (second display update method), the control unit 73 acquires the rotation amount of the rotary dial unit 41, specifies the display object to be finally displayed, and then displays the display object. The display objects corresponding to the passing indicator may be scroll-displayed sequentially. In this case, the display follows the display a little later than the operation of the rotary dial unit 41. However, it is possible to avoid frequently updating the display until the final display is specified. The processing burden on the control unit 73 can be reduced.

  After displaying these on the display 21, the control unit 73 determines whether or not a state in which the rotational position does not vary continues for a predetermined time. Or the control part 73 monitors the input of determination operation. When these occur, the control unit 73 specifies an application corresponding to the display object displayed in the center at this time by using the table 110, ends the reference application, and executes the specified application. At this time, the control unit 73 controls the display 21 to display a screen based on an application to be newly activated instead of the screen for displaying the display object.

  On the other hand, the control unit 73 continues to monitor the operation of the end call key (on-hook key) included in the input operation button 14. When an end key (on-hook key) is operated, the control unit 73 terminates the application being executed under the management of the OS program and then starts the reference application program again. Then, the control unit 73 shifts the display from the screen of the activated application to the standby screen.

  In this way, according to the present invention, the user can surely confirm (recognize) the type of application specified each time rotation occurs, even if it is a small rotary dial, and easy operation by intuition is easy. Can be done.

  In the above-described embodiment, a mobile phone is illustrated as an example of the mobile electronic device. However, the mobile electronic device of the present invention is not limited to the mobile phone, and may be a PDA (Personal Digital Assistant), an electronic dictionary, or the like. Even other portable electronic devices can be applied.
