Description

  The present invention relates to a mobile terminal device and a scroll control method for the mobile terminal device.

  In recent years, mobile terminal devices such as mobile phones having a browser function for browsing the Web and the like have become widespread, and users who use such mobile terminal devices are increasing. As a function for displaying a large amount of information on the screen of the display unit, for example, a scroll function is known.

  A mobile phone that reduces the burden of user key operations by providing an automatic scroll display function has been proposed (see, for example, Patent Document 1). Patent Document 1 describes that automatic scrolling is started and stopped by a user pressing a key.

  In addition, an information display device that realizes efficient information presentation with a simple operation in a limited display environment such as a portable device has been proposed (for example, see Patent Document 2). Patent Document 2 describes that the display movement speed is calculated based on an input from a cursor key or the like that accelerates the speed in the direction each time the button is pressed.

JP 2002-185599 A (paragraph 0018) JP 2000-172403 A (paragraph 0052)

  A mobile terminal device such as a mobile phone does not necessarily have a special input function such as pen input or scroll ring in view of the size and cost of the terminal casing. For example, there are many mobile terminal devices that include only keys for inputting numbers and characters and direction keys for indicating up, down, left, and right.

  In a mobile terminal device that does not have a special input function, in order to scroll the screen when only a part of information is displayed on the screen, for example, the user presses the direction key of the direction in which the user wants to move many times. Or, it is necessary to keep pressing the button to perform the same operation as when the button is continuously pressed. If the user only wants to browse information on the browser but the number of key inputs increases, the user cannot comfortably browse.

  Also, when scrolling using a direction key or the like, each time the direction key is pressed, the cursor changes to the next input text box or link in that direction, and the scroll is not smoothly performed. Therefore, each time the user presses the key, the user must check the screen, and it takes time to determine whether the information he wants to see is displayed.

  In a personal computer or the like, an auto scroll function can be used using a mouse. The auto-scroll function is a function that automatically scrolls in the direction even if the mouse is released when the direction in which the scroll is desired is designated. However, it is difficult to realize an auto scroll function in a portable terminal device that does not have a dedicated input function.

  Patent Document 1 describes that automatic scrolling is started and stopped by a user pressing a key. Japanese Patent Application Laid-Open No. H10-228561 describes that the display moving speed is accelerated each time the cursor key is pressed. However, in the methods described in Patent Documents 1 and 2, when auto-scrolling is performed at high speed, there is a possibility of passing a location where information that the user wants to see is displayed.

  Therefore, the present invention can realize an auto-scroll function even in a portable terminal device that does not have a dedicated input function, and can reduce the possibility of passing through a location where information that the user wants to see is displayed. It is an object of the present invention to provide a scroll control method for a terminal device and a mobile terminal device.

  A mobile terminal device according to the present invention is a mobile terminal device having an operation unit including a plurality of keys, and an auto scroll means for performing auto scroll according to a predetermined operation, and according to the number of times the predetermined key is pressed. Accelerating means for increasing the speed of the auto scroll, decelerating means for reducing the speed of the auto scroll according to the number of times the other predetermined key is pressed, and stopping the auto scroll according to the predetermined key operation. And a stop means.

  A scroll control method for a mobile terminal device according to the present invention is a scroll control method for a mobile terminal device including an operation unit including a plurality of keys, and includes an auto scroll step of performing auto scroll according to a predetermined operation, An acceleration step for increasing the auto scroll speed according to the number of times the key is pressed, a deceleration step for decreasing the auto scroll speed according to the number of times the other predetermined key is pressed, and a predetermined key operation And a stop step for stopping the auto scroll according to the above.

  According to the present invention, even a portable terminal device that does not have a dedicated input function can perform auto-scrolling at a speed desired by the user, and may pass a location where information that the user wants to see is displayed. There is an effect that can be reduced.

Embodiment 1. FIG.
A first embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram illustrating a configuration example of the mobile terminal device according to the first embodiment. The mobile terminal device 1 shown in FIG. 1 includes an auto scroll means 10, an acceleration means 11, a deceleration means 12, and a stop means 14. The mobile terminal device 1 includes an operation unit including a plurality of keys. The mobile terminal device 1 is, for example, a mobile phone, but the mobile terminal device 1 of the present embodiment and other embodiments includes an operation unit including a plurality of keys and a display unit that performs scroll display. It may be a mobile terminal device other than the mobile phone.

  The portable terminal device 1 includes a microcomputer including a CPU that operates according to a program. The microcomputer activates an auto scroll mode in accordance with a predetermined operation so that auto scrolling is possible. Auto scrolling means that the display content on the screen of the display unit is automatically scrolled.

  The auto scroll means 10 performs auto scroll according to a predetermined operation in the auto scroll mode state (a state in which the auto scroll mode is activated). The auto scroll means 10 performs auto scroll at the speed set by the acceleration means 11 and the speed reduction means 12.

  The acceleration means 11 increases the speed of auto scrolling performed by the auto scroll means 10 according to the number of times the key is pressed when a predetermined key of the keys on the operation unit is pressed. Note that the auto scroll means 10 sets the auto scroll speed at the start of auto scroll to a predetermined speed (default value).

  When a predetermined key (a key different from the predetermined key related to the acceleration unit 11) is pressed, the deceleration unit 12 determines the speed of the auto scroll performed by the auto scroll unit 10 according to the number of times the key is pressed. Reduce. The stop means 14 stops the auto scroll according to a predetermined key operation.

  Next, the operation of the first embodiment will be described with reference to FIG. FIG. 2 is a flowchart illustrating an example of processing of the mobile terminal device according to the first embodiment. The first embodiment will be described on the assumption that the auto scroll mode is activated.

  In the state in which the auto scroll mode is activated, the auto scroll means 10 starts auto scroll according to a predetermined operation (step S100). Here, the auto scroll means 10 sets the auto scroll speed to a predetermined speed.

  When a predetermined key is pressed, the acceleration means 11 increases the auto scroll speed to a predetermined speed corresponding to the number of times the key is pressed (step S200). The auto scroll means 10 then performs auto scroll at a speed increased by the acceleration means 11.

  When the predetermined key is pressed, the deceleration means 12 reduces the auto scroll speed to a predetermined speed corresponding to the number of times the key is pressed (step S300). Thereafter, the auto scroll means 10 performs auto scroll at the speed reduced by the speed reduction means 12. The stop means 14 stops the auto scroll when a predetermined key operation is performed (step S400).

  As described above, according to the first embodiment, auto scrolling can be performed at a speed desired by the user. In addition, since the auto scroll speed is reduced, the target information can be easily determined. Therefore, since it becomes easy to stop auto scrolling at a desired position, there is an effect that target information can be easily displayed.

Embodiment 2. FIG.
Next, a second embodiment of the present invention will be described with reference to the drawings. FIG. 3 is a block diagram illustrating a configuration example of the mobile terminal device according to the second embodiment.

  The mobile terminal device 1 shown in FIG. 3 includes an auto scroll means 10, an acceleration means 11, a deceleration means 12, an auto scroll mode activation means 21, and an auto scroll mode end means 22. In the second embodiment, a case where the mobile terminal device 1 includes a determination key and up / down / left / right direction keys will be described as an example. In addition, about the structure part similar to the portable terminal device 1 in 1st Embodiment, the code | symbol same as FIG. 1 is attached | subjected and description is abbreviate | omitted.

  The auto scroll mode starting means 21 starts the auto scroll mode according to a predetermined operation. For example, the auto scroll mode activation means 21 activates the auto scroll mode when a predetermined key is pressed a predetermined number of times during a predetermined period. “A predetermined key is pressed a predetermined number of times in a predetermined period” is an operation in which the enter key is pressed twice in a short period of time, such as 0.5 seconds. Is like double-clicking. The auto scroll mode starting means 21 displays a cursor indicating that the auto scroll mode has been entered on the screen when starting the auto scroll mode.

  The auto scroll mode end means 22 ends the auto scroll mode in response to a predetermined operation. For example, the auto scroll mode end means 22 ends the auto scroll mode when a predetermined key is pressed a predetermined number of times. The auto scroll mode end means 22 deletes the cursor indicating that the auto scroll mode has been entered from the screen when the auto scroll mode is ended.

  In the second embodiment, the acceleration means 11 sets the speed of the auto scroll to a speed one step higher when a predetermined key is pressed once. Further, the deceleration means 12 sets the auto scroll speed to a one-step slower speed when another predetermined key is pressed once.

  Next, the operation of the second embodiment will be described with reference to FIG. First, processing for starting the auto scroll mode will be described. FIG. 4 is a flowchart showing an example of processing in which the auto scroll mode starting means 21 starts the auto scroll mode. In the second embodiment, a case where the auto scroll mode is activated when the browser is activated will be described as an example.

  The auto scroll mode activation means 21 determines whether or not the browser is activated (step S10). If it is determined that the browser is activated (YES), the process proceeds to step S20. If it is determined that the browser is not activated (NO), the process is terminated.

  In step S20, the auto scroll mode starting means 21 determines whether or not a predetermined key has been pressed a predetermined number of times within a predetermined short period. For example, the auto scroll mode starting means 21 determines whether or not the enter key is pressed twice in a short time.

  If it is determined in step S20 that the button has been pressed (YES), the auto scroll mode starting means 21 proceeds to step S30 and starts the auto scroll mode. If it is determined that the button has not been pressed (NO), the auto scroll mode starting means 21 ends the process.

  Next, processing when the auto scroll mode is activated will be described. FIG. 5 is a flowchart illustrating an example of processing in the auto scroll mode of the mobile terminal device according to the second embodiment.

  When the auto scroll mode is started, the auto scroll mode starting means 21 displays a cursor indicating that the auto scroll mode has been entered on the screen. The auto scroll means 10 starts auto scroll in the upward direction or the right direction (step S101).

  The acceleration unit 11 determines whether or not the up key has been pressed (step S201). If it is determined that the button has been pressed (YES), the acceleration means 11 sets the upward auto scroll speed to a one-step higher speed, and the auto scroll means 10 performs auto scroll at the set speed (step S202). If it is determined that the button has not been pressed (NO), the process proceeds to step S301.

  In step S301, the deceleration unit 12 determines whether or not the down key is pressed. If it is determined that the button has been pressed (YES), the deceleration means 12 sets the upward scroll speed to a one-step slower speed, and the auto-scroll means 10 performs auto-scrolling at the set speed (step S302). If it is determined that the button has not been pressed (NO), the process proceeds to step S311.

  In step S311, the deceleration unit 12 determines whether or not the left key has been pressed. If it is determined that the button has been pressed (YES), the deceleration unit 12 sets the scrolling speed in the right direction to a one-step slower speed, and the autoscrolling unit 10 performs autoscrolling at the set speed (step S312). If it is determined that the button has not been pressed (NO), the process proceeds to step S211.

  In step S211, the acceleration unit 11 determines whether or not the right key is pressed. If it is determined that the button has been pressed (YES), the acceleration means 11 sets the scrolling speed in the right direction to a speed one step higher, and the autoscrolling means 10 performs autoscrolling at the set speed (step S212). If it is determined that the button has not been pressed (NO), the process proceeds to step S501. After the processes of steps S202, S212, S302, and S312, the process proceeds to step S501.

  The auto scroll mode end means 22 ends the auto scroll mode when a predetermined key is pressed a predetermined number of times. For example, the auto-scroll mode ending unit 22 determines whether or not the enter key has been pressed twice in a short period (step S501).

  If it is determined in step S501 that the button has been pressed (YES), the process proceeds to step S502. In step S502, the auto scroll means 10 stops scrolling, and the auto scroll mode end means 22 deletes the cursor indicating that the auto scroll mode has been entered from the screen, and ends the auto scroll mode (step S503).

  If it is determined in step S501 that the button has not been pressed (NO), the auto-scroll mode activation means 21 proceeds to step S201 and executes the process again.

  The process of step S100 in the first embodiment includes the process of step S101 in the second embodiment, and the process of step S200 in the first embodiment is the same as steps S201, S202, and The processing of S211 and S212 is included. Further, the process of step S300 in the first embodiment includes the processes of steps S301, S302, S311, and S312 in the second embodiment.

  In the second embodiment, the case where the mobile terminal device 1 includes the determination key and the up / down / left / right direction keys has been described as an example. However, the mobile terminal device 1 includes the determination key and the up / down / left / right direction keys. For example, a numeric key (for example, 2, 4, 6, 8) arranged in a cross shape may be used instead of the direction key, and a numeric key indicating the number 5 may be used instead of the decision key. .

  As described above, according to the second embodiment, even in a mobile terminal device that does not have a dedicated input function such as pen input or scroll ring, the auto scroll mode is started or ended only by key input. Therefore, a more comfortable user interface can be provided.

Embodiment 3. FIG.
Next, a third embodiment of the present invention will be described with reference to the drawings. FIG. 6 is a block diagram illustrating a configuration example of the mobile terminal device according to the third embodiment.

  The mobile terminal device 1 shown in FIG. 6 includes an auto scroll means 10, an acceleration means 11, a speed reduction means 12, an automatic speed reduction means 13, a stop means 14, an auto scroll mode activation means 21, and an auto scroll mode end means. 22. In the third embodiment, a case where the mobile terminal device 1 includes a determination key and up / down / left / right direction keys will be described as an example. In addition, about the structure part similar to the portable terminal device 1 in 2nd Embodiment, the code | symbol same as FIG. 3 is attached | subjected and description is abbreviate | omitted.

  The automatic deceleration means 13 decelerates the speed of auto scroll when a predetermined time corresponding to the number of times a predetermined key is pressed has elapsed. The automatic deceleration means 13 sets a “timer” according to the pressed key, and decelerates the scroll speed when a time-out occurs.

  The “timer” is included in the microcomputer. For example, data corresponding to 10 seconds is set in the “timer”. When the “timer” is activated, it notifies the CPU that it has timed out when the time set by the CPU at the time of activation elapses.

  The stop means 14 stops the auto scroll according to a predetermined key operation.

  Next, the operation of the third embodiment will be described with reference to FIG. FIG. 7 is a flowchart illustrating an example of processing in the auto scroll mode of the mobile terminal device according to the third embodiment. In addition, about the process similar to the process in 2nd Embodiment, the code | symbol same as FIG. 5 is attached | subjected and description is abbreviate | omitted.

  In step S202, the acceleration means 11 sets the speed of the upward auto scroll to a speed that is one step faster, and the auto scroll means 10 performs auto scroll at the set speed. Next, the automatic deceleration means 13 restarts the timer (step S401). For example, if the timer is not started, the automatic deceleration means 13 decreases the timer setting value to 30 seconds, and if the timer is already started, the automatic deceleration means 13 decreases the timer setting value by 10 seconds. If the timer has not yet been started, the process of step S401 is strictly a process of starting the timer.

  In step S302, the deceleration means 12 sets the upward scroll speed to a one-step slower speed, and the auto scroll means 10 performs auto scrolling at the set speed. Next, the automatic deceleration means 13 stops the timer (step S402).

  In step S312, the speed reduction means 12 sets the scrolling speed in the right direction to a one-step slower speed, and the auto scroll means 10 performs auto scrolling at the set speed. Next, the automatic deceleration means 13 stops the timer (step S403).

  In step S212, the acceleration means 11 sets the scrolling speed in the right direction to a speed one step higher, and the autoscroll means 10 performs autoscrolling at the set speed. Next, the automatic deceleration means 13 restarts the timer (step S404). For example, if the timer is not started, the automatic deceleration means 13 decreases the timer setting value to 30 seconds, and if the timer is already started, the automatic deceleration means 13 decreases the timer setting value by 10 seconds. If the timer has not yet been started, the process of step S404 is strictly a process of starting the timer.

  After the processes in steps S401, S402, S403, and S404, the process proceeds to step S405.

  In step S405, the automatic deceleration means 13 determines whether or not the timer is operating. If it is determined that it is operating (YES), it is determined in step S406 whether or not the timer has timed out. If it is determined that the timer has timed out (YES), the automatic deceleration means 13 decelerates the scroll speed (step S407). Thereafter, the auto scroll means 10 performs auto scroll at the speed reduced by the automatic speed reducing means 13.

  If it is determined in step S405 that the timer is not operating (NO), if it is determined in step S406 that the timer has not timed out (NO), and after the process of step S407, the process proceeds to step S501.

  If it is determined in step S501 that a predetermined key operation has been performed, the stopping unit 14 stops auto-scrolling (step S601), and proceeds to step S502. That is, the auto scroll means 10 stops auto scroll according to an instruction from the stop means 14. The predetermined operation is, for example, an operation of pressing the enter key twice in a short time.

  Note that the automatic deceleration means 13 may decelerate the auto scroll speed step by step when decelerating the scroll speed. In the above description, the timer is stopped when the speed reducing unit 12 reduces the speed of the auto scroll (see steps S402 and S403), but the same processing as the processing in steps S401 and S404 may be performed.

  As described above, according to the third embodiment, the speed of auto-scrolling is automatically reduced, so that the possibility that the user wants to see the information displayed is reduced. be able to. In addition, as the scroll speed is increased, the time from when the timer is started until the process of automatically decelerating the scroll speed changes (shortens), so the user is caused by the increase in the scroll speed. Is less likely to pass the location where the information that the user wants to see is displayed.
