Description

  The present invention relates to a display processing method on a display unit of a mobile communication terminal device, and a mobile communication terminal device using the display processing method.

  Conventionally, mobile communication terminal devices such as mobile phone devices have been widely used. In recent years, mobile communication terminal devices can perform various functions by executing programs stored in an internal storage unit, including communication functions such as a call function, an e-mail communication function, and a browser function. It can be done.

  In order to select and execute a program in such a mobile communication terminal device, a method of selecting an icon such as a deployable executable file or a document file displayed on the display unit is generally used as in the case of a personal computer or the like. (Hereinafter referred to as “conventional example”). In this method, icons such as executable files and document files that can be developed are first displayed on the display unit. Subsequently, when the user operates an input device such as a mouse and selects an icon of the file to be expanded, the file is instructed to be expanded. Then, the program corresponding to the expansion of the file instructed to be expanded is executed.

  The technique of the conventional example described above is an excellent technique from the viewpoint that an execution command specifying a program name can be performed more easily than when text is input by operating a stroke device such as a keyboard. However, the technology of the conventional example is a technology that matches a display unit having a sufficiently large display surface and a personal computer or the like to which a keyboard and a mouse can be connected as standard.

  When only a small display surface can be used as in a mobile communication terminal device such as a mobile phone device, only a part of the executable executable file or document file can display an icon that allows the file type to be visually recognized. For this reason, when the icon of the file to be expanded does not exist in the currently displayed display content, it is necessary to switch the display content. Such switching of the display contents is performed by operating a small key in the operation input unit provided in the mobile communication terminal device, but it is a burden on the user to operate the small key many times in some cases. It was.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a display processing method capable of easily switching display contents on a display unit in a mobile communication terminal device.

  Another object of the present invention is to provide a mobile communication terminal device that can easily switch display contents on a display unit.

  From a first aspect, the present invention is a display processing method used in a mobile communication terminal device, the posture angle detecting step for detecting the posture angle of the mobile communication terminal device; and the detection in the posture angle detecting step A posture angle change determining step of determining whether or not the value of the posture angle thus determined has changed from the inside of the predetermined posture angle range to the outside of the predetermined posture angle range; and the determination result in the posture angle determining step is positive A first display switching step of discretely switching display contents on the display unit of the mobile communication terminal device corresponding to the direction of change of the attitude angle.

  Here, “the posture angle value is inside the predetermined posture angle range” means that, for example, when the predetermined posture angle range is −10 ° to 10 °, the posture angle value is θ. Sometimes, it means a case where −10 ° ≦ θ ≦ 10 ° is satisfied. Further, “the posture angle value is outside the predetermined posture angle range” means that, for example, when the predetermined posture angle range is −10 ° to 10 °, the posture angle value is θ. And θ <−10 ° or θ> 10 °. In this specification, the terms “inside of the posture angle range” and “outside of the posture angle range” are used in this sense.

  Also, “discretely switching display contents” means, for example, when switching the display related to the arranged icons, the displayed icons are switched in the arrangement order, but the display position of the icons changes continuously. Instead, the display content is switched in such a manner that the display position of the icon is switched to the position where another icon was displayed. In this specification, the term “discrete switching of display contents” is used in this sense.

  In this display processing method, the attitude angle of the mobile communication terminal device is detected in the attitude angle detection step. Subsequently, in the posture angle change determining step, it is determined whether or not the posture angle value detected in the posture angle detecting step has changed from the inside to the outside of the predetermined posture angle range. Here, the predetermined posture angle range is determined by experiment and experience from the viewpoint of operability. The predetermined attitude angle range may be fixedly set in advance or may be set by the user.

Corresponding to a direction from the inside of the predetermined posture angle range to the outside of the predetermined posture angle range when the determination result in the out of predetermined range continuation determining step is affirmative And a second display switching step of discretely switching display contents on the display unit.

  In this case, in the out-of-predetermined range continuation determining step, it is determined whether or not the state in which the posture angle value exists outside the predetermined posture angle range continues for a predetermined time. If the determination result is affirmative, in the second display switching step, the display content on the display unit is discretely associated with the direction from the inside of the predetermined posture angle range to the outside of the predetermined posture angle range. Can be switched. For this reason, the display content can be continuously switched by making the posture angle value continuously exist outside the predetermined posture angle range.

  Further, in the display processing method of the present invention, the predetermined posture angle range is obtained by setting a rotation angle from the initial posture around at least one of the display vertical axis and the display horizontal axis in the reference posture of the mobile communication terminal device to a predetermined value. The following ranges can be adopted.

  Here, the reference posture can be a posture in which the display surface of the display unit is horizontal. Prior to the posture angle detection step, an initial posture detection step of detecting an initial posture of the mobile communication terminal device may be further provided, and the reference posture may be set as the initial posture.

  In the display processing method of the present invention, the display content may include at least one expandable file symbol virtually arranged along at least one of the display vertical direction and the display horizontal direction. In this case, the screen contents for selecting the expandable file can be switched by a simple operation of changing the attitude of the mobile communication terminal device.

  Here, in the display of the display content, a plurality of the expandable files are displayed, and the expandable files that can be specified for expansion in the expandable files can be highlighted. In this case, a desired expandable file can be expanded very easily.

  According to a second aspect of the present invention, a display unit having a display unit; a posture angle detection unit that detects a posture angle; and a value of a posture angle detected by the posture angle detection unit is within a predetermined posture angle range. Posture angle change determination means for determining whether or not the position has changed from the inside to the outside of the predetermined posture angle range; and when the result of determination by the posture angle determination means is affirmative, Correspondingly, a mobile communication terminal device comprising: display control means for discretely switching display contents on the display unit.

  In this mobile communication terminal device, the posture angle detection means detects the posture angle of the mobile communication terminal device. Subsequently, the posture angle change determining means determines whether or not the value of the posture angle detected by the posture angle detecting means has changed from the inside to the outside of the predetermined posture angle range. If the result of the determination by the posture angle change determination means is affirmative, the display switching means switches the display contents on the display unit in a discrete manner corresponding to the change direction of the posture angle.

  That is, the mobile communication terminal device of the present invention can switch the display content of the display unit using the display processing method of the present invention described above. Therefore, according to the mobile communication terminal device of the present invention, it is possible to easily switch the display content on the display unit.

  In the mobile communication terminal device of the present invention, it is determined whether or not the state in which the posture angle value detected by the posture angle detecting means is outside the predetermined posture angle range continues for a predetermined time. And further including a continuation determination unit outside the predetermined range, and the display control unit, when the determination result in the continuation determination unit outside the predetermined range is affirmative, from the inside of the predetermined posture angle range to the predetermined posture angle range. The display content on the display unit can be switched discretely corresponding to the direction toward the outside.

  In this case, the out-of-predetermined range continuation determining means determines whether or not the state in which the posture angle value exists outside the predetermined posture angle range continues for a predetermined time. If the determination result is affirmative, the display switching means discretely switches the display content on the display unit in a direction from the inside of the predetermined posture angle range to the outside of the predetermined posture angle range. For this reason, the display content can be continuously switched by making the posture angle value continuously exist outside the predetermined posture angle range.

[Operation]
Next, the file viewer application 32 in the mobile phone device 10 configured as described above will be described mainly focusing on display control on the display unit 13.

  When the file viewer application 32 is activated, as shown in FIG. 6, the file viewer application 32 first performs posture angle measurement setting in step S11. Such setting is performed by the display control unit 35 sending a measurement data collection start command and a collection data condition to the measurement data collection processing unit 31.

  The measurement data collection processing unit 31 that has received the measurement start command sends an operation start command to the sensor unit 25. As a result, the operation of the sensor unit 25 is started, and the operation of periodically sending the measurement raw data to the control unit 21 is started. Thereafter, in the control unit 21, the measurement data collection processing unit 31 receives the measurement raw data, performs offset correction and gain correction, and then starts an operation of storing the measurement data satisfying the collection data condition in the temporary storage area 24T. .

  Next, in step S12, the display control unit 35 causes the display unit 13 to display an initial image. In this initial image, the file FS3, which is defined as the initial display file in the file arrangement information, is arranged at the center in the X direction, and the file FS4 adjacent to the file FS3 in the + X direction in the file arrangement information is on the + X direction side. The symbols of the respective files are displayed at the same time in such a manner that the files FS2 arranged and adjacent in the −X direction in the file arrangement information are arranged on the −X direction side. In the initial image, the initial display file that displays the initial display file FS3 in a large size is highlighted. An example of such an initial image is shown in FIG.

  Next, in step S <b> 13, the display control unit 35 determines whether or not the enter key is pressed on the operation unit 12. If the result of this determination is affirmative, the display control unit 35 ends the process. As a result, the execution of the file viewer application 32 ends. Thereafter, the highlighted file is expanded.

  If the result of the determination in step S13 is negative, the process proceeds to step S14. In step S <b> 14, the display control unit 35 sends a measurement data request specifying the notification data condition to the measurement data collection processing unit 31.

The measurement data collection processing unit 31 that has received the measurement data request reports measurement data that satisfies the notification data condition to the file viewer application 32. In the file viewer application 32, the posture change detection unit 33 and the change continuation detection unit 34 receive measurement data reported from the measurement data collection processing unit 31. Then, the posture change detection unit 33 detects a transition from the non-rotation state to the right rotation state and a transition from the non-rotation state to the left rotation state based on the reported measurement data. Further, the change continuation detecting unit 34 detects the transition to the continuation of the time T _{0 in} the right rotation state and the continuation of the time T _{0 in} the left rotation state by using the time measurement result by the timer 29. The detection results by the posture change detection unit 33 and the change continuation detection unit 34 are reported to the display control unit 35.

  Next, in step S15, the display control unit 35 performs display switching processing. In this display switching process, as shown in FIG. 8, first, in step S21, the display control unit 35 determines whether or not a transition from the non-rotation state to the right rotation state is reported from the posture change detection unit 33. To do.

  If the result of the determination in step S21 is affirmative, the process proceeds to step S26. In step S26, the display control unit 35 highlights a file that is adjacent to the currently highlighted file in the −X direction in the file arrangement information at the display position of the highlighted file in the currently displayed image. Switch to the displayed image display. Accordingly, the highlighted file is not highlighted on the + X direction side of the new highlighted file, and a file adjacent to the new highlighted file in the −X direction in the file arrangement information is new. The highlight file is not highlighted on the −X direction side. An image display example thus switched from the display example of FIG. 7 is shown in FIG.

If the determination result in step S21 is negative, the process proceeds to step S22. In step S22, whether it has been reported that from the change continuation detecting section 34 is continued clockwise rotation state a predetermined time T ₀ or more is determined.

  If the determination result in step S22 is affirmative, the process proceeds to step S26. Then, the display control unit 35 executes the process in step S26 described above.

  If the result of the determination in step S22 is negative, the process proceeds to step S23. In step S23, the display control unit 35 determines whether or not the transition from the non-rotation state to the left rotation state is reported from the posture change detection unit 33.

  If the result of the determination in step S23 is affirmative, the process proceeds to step S25. In step S25, the display control unit 35 highlights a file adjacent to the currently highlighted file in the + X direction in the file layout information at the display position of the highlighted file in the currently displayed image. Switch to the displayed image. Accordingly, the highlighted file is not highlighted on the −X direction side of the new highlighted file, and a file adjacent to the new highlighted file in the + X direction in the file arrangement information is newly added. The highlighted file is not highlighted on the + X direction side. An image display example thus switched from the display example of FIG. 7 is shown in FIG.

If the result of the determination in step S23 is negative, the process proceeds to step S24. In step S24, whether it has been reported that from the change continuation detecting section 34 and continued counterclockwise rotation state a predetermined time T ₀ or more is determined.

  If the result of the determination in step S24 is affirmative, the process proceeds to step S25. Then, the display control unit 35 executes the process in step S25 described above.

  If the result of the determination in step S24 is negative, the process of step S15 ends without performing display switching. Moreover, also when the process of step S25 or step 26 is complete | finished, the process of step S15 is complete | finished. Then, the process proceeds to step S13 in FIG. Thereafter, the processes in steps S13 to S15 described above are repeated until the result of the determination in step S13 becomes affirmative.
