Further, when browsing long documents that are often scrolled, it is possible to browse all documents with a minimum of input operations.

  Hereinafter, the present invention will be specifically described with reference to the drawings.

  In the present embodiment, a case will be described in which a portable terminal having a touch panel browses an amount of data that does not fit in the information display area of the touch panel using a stylus pen (hereinafter, “pen”).

  FIG. 1 is a block diagram showing a configuration of a mobile terminal to which an automatic scroll control device according to an embodiment of the present invention is applied.

  The portable terminal 100 includes an input unit 1 having a touch panel pressure sensing unit (not shown), a CPU 2 that controls processing of the entire terminal, a display unit 3 such as an LCD, a ROM 4a that stores a control program for the terminal, and a working memory. A RAM 4b that plays the role of, a storage unit 4c that reads and writes data and programs by inserting an external memory, a communication control unit 5 that wirelessly communicates with an external terminal, and a bus 6 that connects these components to each other I have.

  FIG. 2 is a block diagram illustrating a partial functional configuration of the mobile terminal 100. The same components as those in FIG. 1 are denoted by the same reference numerals.

  The input unit 1 includes a scroll operation input area 11 and refers to a pressure-sensitive unit of a touch panel here. The scroll operation input area 11 recognizes the user's operation and detects the presence or absence of contact on the touch panel and the single contact position where the contact occurred.

  The scroll control unit 22 performs scroll processing of the information display area based on information from the automatic scroll control unit 21 and instructs the display control unit 23 to display the scroll processing result. In the present embodiment, the automatic scroll control unit 21 and the scroll control unit 22 are composed of the CPU 2 in the portable terminal 100 and the ROM 4a for storing the control program, and the display control unit 23 is composed of the CPU 2 and the ROM 4a for storing the control program.

  In the conventional scroll control, information such as coordinate values from the scroll operation input area 11 is transmitted to the scroll control unit 22, but in this embodiment, the automatic operation is automatically performed between the scroll operation input area 11 and the scroll control unit 22. A scroll control unit 21 is newly provided. The automatic scroll control unit 21 monitors the input operation in the scroll operation input area 11 and notifies the scroll control unit 22 of information for scrolling based on the monitoring result.

  The automatic scroll control unit 21 monitors the presence or absence of contact on the touch panel on the scroll operation input area and the contact position of one contact point, and instructs the scroll control unit 22 to control scrolling and automatic scrolling.

  The automatic scroll controller 21 is roughly divided into an automatic scroll start process, an automatic scroll feed process, and an automatic scroll stop condition determination process.

  The display unit 3 includes an information display area 31 and a scroll bar display area 32. A part of data such as text and images is displayed in the information display area 31.

  The storage unit 4 in FIG. 2 is a storage device used by the three control units of the automatic scroll control unit 21, the scroll control unit 22, and the display control unit 23, and corresponds to the RAM 4b in FIG.

  FIG. 3 is a diagram illustrating a specific configuration of the display unit 3. As shown in FIG. 3, a knob 33 is displayed on the scroll bar display area 32.

  As a general operation of the scroll bar, the screen in the information display area 31 is scrolled by one line by tapping the arrows at both ends in the scroll bar display area 32 with a pen, and the area between the arrows excluding the knob 33 is tapped. Scrolls the screen by one screen. Each time the user scrolls, the knob 33 moves to an approximate position in the entire document in the displayed portion. Further, by dragging the knob 33, the knob 33 is moved, and the screen is scrolled corresponding to the moved position to display a part of the document.

  FIG. 4 is a flowchart showing an automatic scroll start process executed by the automatic scroll control unit 21.

  In this process, the automatic scrolling is started by performing an operation of flipping the knob 33. Therefore, in the automatic scroll start process, it is monitored that the user performs an operation of repelling the knob 33 from the input operation on the scroll operation input area 11.

  As the automatic scroll start process, first, the position of the knob 33 is acquired from the scroll control unit 22 (step S1). This is used to determine whether the pen is in contact with the knob 33.

  Next, it is determined whether or not the pen is in contact with the knob 33 (step S2). In step S2, step S6 and step S10, which will be described later, processing is determined using the presence or absence of pen contact and the coordinate value of the pen. The information on these pens is acquired from the scroll operation input area 11 and is information obtained by the scroll control unit 22 in the past. However, in this embodiment, the automatic scroll control unit 21 serves as a filter, and scroll Before the pen information is sent to the control unit 22, the operation of repelling the knob 33 is monitored.

  In the automatic scroll start process, the input operation other than the repelling operation is the same scrolling operation as in the prior art, and the input operation is directly performed in step S3, step S4, step S9, and step S13 as described below. 22 is notified (transferred).

  If the result of the determination in step S2 is that the pen is not in contact with the touch panel or is in contact but not on the knob 33, the scroll controller 22 is notified of the presence or absence of contact and the coordinate value of the contact point (step S3), returning to step S1. Therefore, the scroll control unit 22 is directly notified of the input state of the scroll operation input area 11 until the pen touches the knob 33 that is the starting point for the operation of flipping the knob 33. That is, the operation is the same as that of the conventional scroll control until an operation of repelling the knob 33 is detected. At this time, when there is no need to notify the scroll control unit 22 such as a state where there is no contact with the touch panel, the scroll control unit 22 is not notified.

  When the pen touches the knob 33, the contact and the coordinate value of the contact point are sent to the scroll control unit 22 (step S4). At this time, it cannot be determined whether the subsequent input operation is a drag operation of the knob 33 or a repelling operation. Therefore, at this point, the fact that the drag operation has been started is sent to the scroll control unit 22 and the coordinate value of the contact point. From the next step S5, the process is to determine whether or not the pen has repelled the knob 33.

  Here, the feature of the operation of repelling will be described using brush writing as an example.

  Considering a series of operations such as contact between the pen and the touch panel, movement of the pen while touching, and separation of the pen from the touch panel when the operation is performed with the pen on the touch panel, the operation was performed with the pen on the touch panel. The operation at the time is the same as the operation when the drag operation is performed. However, it is generally considered rare for a user to perform a drag operation by a repelling action, and here, the repelling operation is considered separately from the drag operation.

  FIG. 5 is a diagram illustrating an example in which “Harai” and “Tame” are performed by brush writing.

  When the drag operation is applied to the operation “stop”, the operation of repelling has characteristics similar to the operation of “hari”. “Tome” brings the brush into contact with the paper, moves in contact with the paper, stops, and then removes the brush from the paper. In contrast, "Harai" moves the brush away from the paper. Therefore, if the interval between the time when the brush “moves” on the paper and the time when the brush “moves” from the paper is compared between the two, “Hara” is extremely short.

  In this embodiment, a repelling operation is recognized using this feature. In general, it is unlikely that you will perform a drag operation with the intention of pausing and releasing it from the touch panel, as in the case of “Tome” in brush writing. Since it is extremely short compared to the drag operation, the repelling operation and the drag operation can be recognized separately.

  Since the boundary of the time interval for recognizing repelling depends on the performance of a device such as a touch panel and individual differences, in this embodiment, a threshold value for separating a repelling operation and a dragging operation is provided, and the storage unit 4 stores the threshold value The threshold storage area 41 is provided. A storage area of the storage unit 4 is shown in FIG. In addition, the storage unit 4 includes two storage areas for automatic scroll start processing. One is a movement time storage area 42 for storing the time every time the pen in contact with the touch panel moves. This is for obtaining a time interval until the pen leaves the movement. Next, there is a coordinate value storage area 43 for storing the coordinate value of the contact point when the pen moves in order to calculate the speed when the pen is repelled. A dotted line in FIG. 6 represents a division for each process, a storage area straddling the dotted line represents a storage area shared by the processes in these two areas, and only the process is within the dotted line. This is the storage area to be used.

  Based on the above, the processing after step S5 in FIG. 4 will be described.

  First, the coordinate value of the contact point at which the pen touches the touch panel is stored in the coordinate value storage area 43 (step S5). This is to determine whether the pen has moved in the next step S6.

  In step S6, the previously stored coordinate value is compared with the coordinate value stored in the coordinate value storage area 43 in step S5 to determine whether or not the pen has moved.

  If the pen is moving in step S6, the coordinate value of the contact point after the movement is stored in the coordinate value storage area 43 (step S7). This is stored in order to determine whether the pen has moved again and to calculate the speed when the pen is repelled.

  Next, the time at the start of movement is stored in the movement time storage area 42 in milliseconds (step S8). This is stored in order to determine whether or not the pen is repelled and to calculate the speed when the pen is repelled. Then, the scroll control unit 22 is notified of the movement and the coordinate value of the contact point (step S9). This is to notify that the drag of the knob 33 is being performed because the pen is still in contact with the touch panel and moved in that state. Therefore, in this step S9, the display unit 3 is in a state of being scrolled by dragging the knob 33.

  If the pen is not moving in step S6, or after the process of step S9, it is determined whether the pen is away from the touch panel (step S10).

  If the result of determination in step S10 is that the pen is not separated from the touch panel, the process returns to step S6. That is, steps S6 to S10 are repeated until the pen leaves the touch panel. As a result of the determination in step S6, the coordinate value storage area 43 always stores the coordinates of the contact point that has moved last. Note that not only the coordinates of the contact point that has moved last, but also the coordinates of the contact point that has been moved several times before may be stored. The movement time storage area 42 stores the last movement time. Note that not only the time of the last movement but also the movement times up to several times before may be stored.

  If the result of the determination in step S10 is that the pen is away from the touch panel, the time when the pen is removed from the touch panel is stored in the movement time storage area 42 (step S11), and the knob 33 is flicked with the pen. Whether or not (step S12). Whether or not the operation is a repelling operation is determined as follows.

  First, the difference between the time when the pen has moved away from the touch panel and the time when the pen moved last is stored in the movement time storage area 42 and compared with the threshold value in the threshold storage area. If the time interval is smaller than the threshold value, it is determined that the operation is a repelling operation, and the automatic scroll feed process is started (step S13).

  When the automatic scroll feed process is executed, the repelling speed is stored and used in the automatic scroll feed process. The repelling speed is calculated from the moment when the pen leaves and the coordinates of the contact point can be obtained accurately, and from the stored last time the contact point moved and the coordinates of the contact point. Also, if the time when the pen leaves and the coordinates of the contact point cannot be obtained accurately, the difference between the coordinate of the contact point moved last and the coordinate of the contact point at the previous movement is It is good also as the speed which repelled the value divided by the difference of the time of the last movement. Further, if the repelling speed calculated by the above method or the like is less than a predetermined value, it is determined that the drag operation is performed, and if it is equal to or greater than the predetermined value, it is determined that the operation is a repelling operation.

  Further, the scroll control unit 22 is not notified that the pen has been removed at the time of the process of step S13. Therefore, since the scroll control unit 22 recognizes that the pen is dragging on the knob 33, in the automatic scroll feed process described later, the scroll control unit 22 is informed that the pen is moving while contacting, Scrolling is performed on the display unit 3.

  As a result of the determination in step S12, when the knob 33 is not an operation of repelling with a pen, that is, when it is a drag operation, or after entering the automatic scroll feed process by the flip operation, the stop condition is satisfied and the end of the automatic scroll feed process is completed. When the determination is made, the scroll control unit 22 is notified of the absence of contact between the pen and the touch panel and the coordinate value of the last contact point (step S14), and the process returns to step S1. Thereby, the scroll control unit 22 determines that the scrolling by dragging the knob 33 is finished.

  FIG. 7 is a flowchart showing an automatic scroll feed process executed by the automatic scroll control unit 21.

  The automatic scroll feed process is executed when the automatic scroll start process detects an operation of repelling the knob, receives the notification of execution, and transfers the repelled speed.

  As illustrated in FIG. 6, the storage unit 4 includes a scroll speed storage area 44 that stores a speed for automatic scrolling and a display amount of data to be scrolled by one scroll (hereinafter referred to as “scroll”). A scroll feed amount storage area 45 for storing the “feed amount”), a scroll time interval storage area 46 for storing the time interval for executing the scroll, and a time storage area 47 for storing the time at which the scroll is executed. .

  As for the contents of the automatic scroll feed processing, first, the scroll speed is calculated from the repelled speed (step S21). Here, the scrolling speed is used as it is as the scrolling speed, but the scrolling speed may be determined linearly or nonlinearly with the flipping speed as a reference value. The scroll speed can also be accelerated or decelerated over time. The calculated or determined scroll speed is stored in the scroll speed storage area 44.

  Then, the time interval for executing scrolling is calculated based on the scroll feed amount stored in advance in the scroll feed amount storage area 45 and the scroll speed calculated or determined in step S21 (step S22). In the present embodiment, the time interval for executing scrolling is calculated by scroll feed amount / scroll speed. The calculated time interval is stored in the scroll time interval storage area 46.

  Next, the coordinate value at which the pen is in contact with the touch panel is acquired from the coordinate value storage area 43 used in the previous automatic scroll start process. That the coordinate value plus the scroll feed amount in the scroll feed amount storage area 45 is stored in the coordinate value storage area 43 as a new pen position, and the scroll controller 22 has moved the pen to the new coordinate value Is notified (step S23).

  Although the pen is actually separated from the touch panel during the automatic scroll feed process, the scroll control unit 22 is still in contact with the scroll control unit 22 because it has not been notified to the scroll control unit 22 in the automatic scroll start process. It is recognized that Therefore, the scroll control unit 22 scrolls the display unit 3 as if the knob 33 was dragged.

  And the present time is memorize | stored in the time memory area 47 as time which performed scroll (step S24). This is used later to determine whether the time interval for scroll execution has elapsed.

  From here, step S25 to step S28 are repeated until the time interval of scroll execution elapses.

  First, in automatic scroll stop condition determination processing (step S25), which will be described later, it is determined whether to stop or continue automatic scroll (step S26). If there is an instruction to stop, automatic scroll is terminated (step S27). .

  If an instruction to continue automatic scrolling is given in the previous step S25, the time at which scrolling is executed is acquired from the time storage area 47, and the current time is stored in the scroll time interval storage area 46 for executing scrolling. It is determined whether minutes have passed (step S28). If the scroll execution time interval has not elapsed, the process returns to step S25, and automatic scroll stop condition determination processing is performed. On the other hand, if the time interval for executing the scroll has elapsed, the process returns to step S23 and the scroll is executed again. When the scroll speed is accelerated or decelerated over time, it is possible to return to step S21 and recalculate the scroll speed.

  From the above, by repeating steps S23 to S28, the scroll control unit 22 is instructed to scroll at regular intervals, and automatic scrolling is performed. When the automatic scroll stop condition is satisfied, the process returns to the automatic scroll start process in step S13 of FIG. 4, and the scroll control unit 22 is notified that the pen has been removed in step S14. The scrolling by dragging also ends.

  FIG. 8 is a flowchart showing an automatic scroll stop condition determination process executed by the automatic scroll control unit 21.

  In the present embodiment, the automatic scrolling is stopped using the tapping of the knob 33 as a stop condition. In addition, play is provided on the top and bottom or left and right of the knob 33 when it is difficult to tap the knob 33 accurately, such as when scrolling at high speed.

  First, it is determined whether or not the pen is in contact with the touch panel (step S31). If the pen is not in contact with the touch panel, the stop condition is not satisfied, and an instruction to continue automatic scrolling is returned to the automatic scroll feed process that is the caller of the process (step S32).

  Next, if the pen is in contact with the touch panel, the position and range of the scroll bar and the position and range of the knob 33 are acquired from the scroll control unit 22 (step S33).

  Then, it is determined whether or not the knob 33 is located at the end of the scroll bar, that is, whether or not the knob 33 cannot be scrolled any more (step S34). If the knob 33 is in a position where it cannot be scrolled any more, an instruction to stop automatic scrolling is returned to the automatic scroll feeding process which is the caller of the process (step S35).

  On the other hand, if the knob 33 is in a position where it can be scrolled, the scroll speed is acquired from the scroll speed storage area 44, and the amount of play applied to the knob 33 is set (step S36). Here, the play shown in FIG. 9 was set. The play shape is a rectangle, and the value obtained by multiplying a certain value by the speed value is the vertical length of the play rectangle so that the play increases in proportion to the speed.

  The rectangles obtained as described above are arranged at both ends of the knob 33, and it is used as a virtual knob range to determine whether or not the pen is in that range, that is, whether the pen is in contact with the virtual knob. It discriminate | determines (step S37). Here, since the play rectangle is not displayed, the appearance of the knob does not change. However, the size of the knob 33 may be increased within the range including play depending on the scroll speed of the display unit 3.

  If the pen is in contact with the range of the knob including the play, an instruction to stop the automatic scroll is returned to the automatic scroll feed process that is the caller of the process (step S38). On the other hand, if the pen is not in contact with the range of the knob including play, an instruction to continue automatic scrolling is returned to the automatic scroll feed process that is the caller of the process (step S39).

  As described above in detail, according to the present embodiment, the scroll process is continuously performed according to the scroll input operation in the scroll operation input area 11, and the display unit 3 is based on the result of the scroll process. Since the scroll-processed screen is displayed on the screen, it is possible to provide an interface that can easily meet the user's request without changing the appearance of the scroll bar. Further, when browsing long documents that are often scrolled, it is possible to browse all documents with a minimum of input operations.

  Further, the automatic scroll control unit 21 monitors the length of the input operation time in the scroll operation input area 11 and when detecting that the knob 33 on the scroll bar display area 32 is repelled (step S12), the automatic scroll feed is performed. The process is executed (step S13), that is, the scroll control unit 22 is controlled so as to continue the scroll process. Therefore, since the knob 33 moves like an object having inertia, the user can perform an intuitive operation. Automatic scrolling can be controlled.

  Further, the automatic scroll control unit 21 calculates the speed of the input operation from the amount of change in the input operation position in the scroll operation input area 11 and the length of the input operation time (step S21), and the calculated speed of the input operation is calculated. The scroll controller 22 is controlled so that the corresponding scroll process is executed (steps S21 to S28). Specifically, the automatic scroll control unit 21 calculates the speed of the input operation from the amount of change in the input operation position in the scroll operation input area 11 and the length of the input operation time (step S21), and the calculated input operation A time interval for executing the scrolling is calculated based on the scrolling speed corresponding to the speed and the predetermined scrolling amount (step S22), and the scroll controller 22 is controlled based on the time interval for executing the scrolling (step S23). Thus, automatic scrolling according to the speed of the input operation is executed, and an interface that can easily respond to the user's request can be provided without changing the appearance of the scroll bar.

  Further, when the automatic scroll control unit 21 causes the scroll control unit 22 to continue the scroll process, the automatic scroll control unit 21 monitors the input operation position in the scroll operation input area 11 and the input operation position is scrolled. When it is detected that the knob 33 in the bar display area 32 has been touched (step S37), the scroll controller 22 is controlled to stop the scroll process (step S38). That is, since the automatic scrolling is stopped by tapping the knob 33, the user can control the automatic scrolling with an intuitive operation. Since the same control is executed even when the input operation position in the scroll operation input area 11 is within the play range of the knob 33, the user can control the automatic scrolling with an intuitive operation. Further, since the knob 33 is provided with play according to the speed of automatic scrolling or the knob 33 is enlarged, it is possible to provide an interface that can easily meet the user's request even when the knob is moving at high speed. it can.

  In the above embodiment, the scroll operation input area 11 is the pressure-sensitive part of the touch panel. However, the touch panel normally covers the entire display screen, and the right or lower band-like portion of the display screen is the scroll operation input area. There are many cases. However, the scroll operation input area 11 may be arranged at an arbitrary position on the touch panel. Further, the scroll operation input area 11 may be moved by a user operation.

  In addition, an object of the present invention is to supply a storage medium storing software program codes for realizing the functions of the embodiments to a system or apparatus, and a computer (or CPU, MPU, etc.) of the system or apparatus as a storage medium. This can also be achieved by reading and executing the stored program code.

  In this case, the program code itself read from the storage medium realizes the functions of the above-described embodiments, and the program code and the storage medium storing the program code constitute the present invention.
