  Hereinafter, embodiments of the present invention will be described with reference to the drawings. The configuration of the following embodiment is an exemplification, and the present invention is not limited to the configuration of the embodiment.

<First Embodiment>
In the first embodiment, a mobile terminal equipped with a touch panel display detects the sliding movement of a finger on the touch panel instructing the moving direction of the display screen upon input of an instruction from the user, and the amount of movement based on the sliding movement The vector is acquired, and the origin of the display screen is moved by the moving amount vector. By moving the display screen of the mobile terminal by the amount of movement vector, for example, when holding the mobile terminal with one hand, the icon that was outside the finger reachable range moves into the finger reachable range, The operation can be continued without changing the terminal, and the operability of the portable terminal is improved.

  The mobile terminal is, for example, a smartphone, a mobile phone terminal provided with a touch panel display, a music playback device provided with a touch panel display, a tablet terminal provided with a touch panel display, a game machine provided with a touch panel, or the like. The first embodiment will be described assuming that the mobile terminal is a smartphone. A portable terminal is an example of an “information processing apparatus”.

  FIG. 1 is a diagram illustrating an example of an appearance of the mobile terminal 1 according to the first embodiment. The mobile terminal 1 includes a touch panel display 2 on the front surface and a mode change button 3 on the left side surface as viewed in the figure. The mode change button 3 is a button that triggers the start of a mode in which the origin of the display screen can be moved by being pressed.

  When the mobile terminal 1 is held with the right hand, the mode change button 3 is arranged at a position where it can be kept pressed down for a predetermined time with at least one of the index finger, middle finger, ring finger, and little finger of the right hand. For example, the mode change button 3 is installed in the vicinity of the midpoint of the left side surface in the longitudinal direction as viewed in the figure of the mobile terminal 1. The mode change button 3 is an example of an “input button”.

In the touch panel display 2, a touch panel is disposed on the front surface of the display, and the display and the touch panel appear to be integrated with each other in appearance. Each of the display and the touch panel has a coordinate system. The display coordinate system is a coordinate system of the display screen, and has an X axis and a Y axis. The coordinate system of the touch panel is a position input coordinate system, and has an X axis and a Y axis. In the first embodiment, it is assumed that the origin of the display screen coordinate system and the position input coordinate system is movable. Hereinafter, the coordinate system of the display is referred to as a front screen coordinate system. The coordinate system of the touch panel is referred to as a position input coordinate system.

  The information processing apparatus 1 holds an association between the position input coordinate system and the display screen coordinate system. In the first embodiment, a third coordinate system is used as the reference coordinate system in addition to the position input coordinate system and the display screen coordinate system. Correspondence between the position input coordinate system and the display screen coordinate system is performed by the reference coordinate system. The origin of the reference coordinate system is fixed. For example, the top left apex of the touch panel display 2 is set as the origin, the short direction of the touch panel display 2 is set as the X axis, and the long direction is set as the Y axis. In the figure, the right direction is the + X direction and the left direction is the -X direction. In the figure, the downward direction is the + Y direction, and the upward direction is the -Y direction. In the initial state, the position input coordinate system and the display screen coordinate system match the reference coordinate system and the origin, the X axis, and the Y axis. However, the association between the position input coordinate system and the display screen coordinate system is not limited to using the third coordinate system. For example, when the origin of the position input coordinate system is fixed, the position input coordinate system is It may be used as a reference coordinate system.

  In the first embodiment, the process of moving the origin of the display screen coordinate system is performed as follows, for example. First, for example, when the portable terminal 1 is held by one hand with the right hand, the user presses the mode change button 3 with at least one of the index finger, middle finger, ring finger, and little finger of the right hand. Thereby, the process of moving the origin of the display screen coordinate system is started. While the mode change button 3 is pressed, the user slides the right thumb on the touch panel display 2 in the direction in which the user wants to move the screen. When this slide movement is detected, the mobile terminal 1 moves the origin of the display screen in the slide movement direction, and the display screen moves in the slide movement direction. If the movement of the display screen is as desired, the user lifts his finger from the mode change button 3 (pushing up), thereby ending the process of moving the origin of the display screen coordinate system. Thereafter, when the mode change button 3 is pressed and pushed up again, the origin of the display screen coordinate system is reset, and the display screen returns to the original position.

FIG. 2 is a diagram illustrating an example of a hardware configuration of the mobile terminal 1. The mobile terminal 1 includes a CPU (Central Processing Unit) 101, a storage unit 102, a touch panel 103, a display 104, a wireless unit 105, an audio input / output unit 106, a speaker 107, a microphone 108, and an antenna 110.

  The storage unit 102 includes a ROM (Read Only Memory) 102a and a RAM (Random Access Memory) 102b. The RAM 102b includes both volatile and nonvolatile ones. The ROM 102a stores a display screen origin movement program. The display screen origin moving program is started by pressing the mode change button 3, detects the sliding movement of the finger on the touch panel 103 indicating the screen moving direction, and moves the display screen coordinate system of the display 104 in the direction of the sliding movement. This is a program for moving the origin. The display screen origin movement program may be stored in the nonvolatile RAM 102b. In addition, a program such as an OS (Operation System) is also stored in the ROM 102b or the nonvolatile RAM 102a.

  The touch panel 103 is one of position input devices, and is arranged on the surface of the display 104, and outputs the coordinates of the finger touch position in the position input coordinate system to the CPU 101. Hereinafter, the coordinates of the touch position on the touch panel 103 are referred to as touch coordinates. The touch panel 103 is a capacitive type in the first embodiment. However, it is not limited to this. For example, the touch panel 103 may be a resistance film method, a surface acoustic wave method, an infrared method, an electromagnetic induction method, or the like.

  The display 104 is, for example, a liquid crystal display (LCD). The display 104 displays screen data according to a signal input from the CPU 101. The display instruction from the CPU 101 is an instruction in the display screen coordinate system, and the display 104 performs display processing in the display screen coordinate system. In addition, the touch panel display 2 in FIG. 1 represents that the display 104 and the touch panel 103 are seen integrally from the external appearance. Hereinafter, the touch panel display 2 may be simply referred to as the touch panel 2. In the description of the external appearance, the touch panel 2 may be used separately from the touch panel 103 in the description of the internal processing.

  The wireless unit 105 is connected to the antenna 110, converts a wireless signal received through the antenna 110 into an electrical signal and outputs the electrical signal to the CPU 101, or converts an electrical signal input from the CPU 101 into a wireless signal and transmits the antenna. 110 to transmit. The wireless unit 105 is, for example, an electronic circuit corresponding to one or more of a third generation mobile communication system, a second generation mobile communication system, and LTE (Long Term Evolution).

  The audio input / output unit 106 is connected to a speaker 107 as an audio output device and a microphone 108 as an audio input device. The audio input / output unit 106 converts an audio signal input from the microphone 108 into an electric signal and outputs the electric signal to the CPU 101, or converts an electric signal input from the CPU 101 into an audio signal and outputs the audio signal to the speaker 107. To do.

  Note that the hardware configuration of the mobile terminal 1 is not limited to that shown in FIG. 2, and can be appropriately changed such as addition, replacement, and deletion. For example, the mobile terminal 1 may include an infrared communication unit, an IC card communication unit, and the like in addition to the configuration shown in FIG. The mobile terminal 1 is an example of an “information processing apparatus” in the aspect.

  FIG. 3 is a diagram illustrating an example of functional blocks of the mobile terminal 1. The portable terminal 1 includes a control unit 11, a position input unit 12, a display processing unit 13, a button operation detection unit 14, and an origin holding unit 15 as functional blocks. For example, the control unit 11 and the origin holding unit 15 are realized by the CPU 101 executing a display screen origin moving program stored in the ROM 102a or the RAM 102b. Further, the position input unit 12, the display processing unit 13, and the button operation detection unit 14 are realized by drivers of the touch panel 103, the display 104, and the mode change button 3, respectively. However, the present invention is not limited to this, and these functional blocks may be realized by hardware such as an FPGA.

  For example, when the position input unit 12 scans the sensor at a predetermined cycle and detects a change in capacitance due to a finger touching the touch panel 103 or the like, the position input unit 12 acquires the coordinate of the capacitance change and notifies the control unit 11 of the coordinate. The coordinates notified by the position input unit 12 are coordinates in the position input coordinate system. The predetermined period is, for example, 10 milliseconds to 100 milliseconds.

  The display processing unit 13 generates a display screen of the display 104 and outputs the generated display screen to the display 104 for display. The display processing unit 13 performs control in the display screen coordinate system. The button operation detection unit 14 detects pressing and raising of the mode change button and notifies the control unit 11 of it.

  The origin holding unit 15 stores the origin of the position input coordinate system and the display screen coordinate system. In the first embodiment, since the reference coordinate system is used, the origin of the position input coordinate system and the display screen coordinate system is indicated by the coordinates of the reference coordinate system. The origin holding unit 15 is generated, for example, in the storage area of the RAM 102b.

  Upon receiving notification of pressing of the mode change button 3 from the button operation detection unit 14, the control unit 11 thereafter records the finger touch coordinates input from the position input unit 12 and detects slide movement. The sliding movement indicates that the finger moves on the touch panel 103 while being in contact with the touch, and is detected by moving touch coordinates that are continuously input from the position input unit 12 at a sensor scanning interval by a predetermined distance or more. Further, the slide movement input after the mode change button 3 is pressed indicates the moving direction of the display screen. The control unit 11 obtains a movement amount vector of the origin of the display screen coordinate system from the slide movement vector and the slide movement start coordinates, and moves the origin of the display screen coordinates by the movement amount vector. Details of the calculation of the movement amount vector will be described later with reference to FIG.

  FIG. 4 is a diagram illustrating an example of area division of the touch panel 103. In the example shown in FIG. 4, the touch panel 2 is divided into three regions in the short direction. Area A is an area above the touch panel. Area B is an area in the middle of the touch panel. Area C is an area below the touch panel. The range of each area is set in advance and stored in the storage area of the RAM 102b of the portable terminal 1.

It is predicted that the position at which the user holds the mobile terminal 1 with one hand will be lower as the start coordinates of the slide movement are lower with the areas A, B, and C. As the position where the portable terminal 1 is held by one hand becomes lower, the reachable range of the thumb of the hand holding the one hand to the area above the touch panel 2 (for example, the area A) becomes narrower. In addition, operation objects such as icons are often arranged in order from the upper part of the screen, and when holding the lower part of the mobile terminal 1 with one hand, it may be impossible to touch the icon or the like located at the upper part of the screen.

  Therefore, when the slide movement is in the lower direction of the screen (+ Y-axis direction), the control unit 11 displays the amount of movement in the + Y-axis direction as the area including the start coordinate of the slide movement is lower. Determine the movement vector of the origin of the screen coordinate system. Hereinafter, the start coordinates of the slide movement are referred to as touch start coordinates.

  More specifically, it is as follows. The touch start coordinates are (XS, YS), and one of the coordinates in the slide is (XT, YT). The touch start coordinates (XS, YS) and one of the coordinates in the slide (XT, YT) are both coordinates in the position input coordinate system. The control unit 11 obtains a slide movement vector (XT-XS, YT-YS). When YT−YS> 0, that is, when the slide movement is in the + Y direction, the control unit 11 determines whether the touch start coordinate (XS, YS) is within the display screen coordinate system. Determine the movement vector of the origin.

  When the touch start coordinates (XS, YS) are in the area A, the control unit 11 obtains, for example, a movement amount vector as (dx, dy) = (XT−XS, YT−YS). When the touch start coordinates (XS, YS) are within the region B, the control unit 11 obtains, for example, the movement amount vector (dx, dy) = (XT−XS, (YT−YS) × 2). When the touch start coordinates (XS, YS) are within the region C, the control unit 11 obtains, for example, the movement amount vector (dx, dy) = (XT−XS, (YT−YS) × 3).

  The control unit 11 adds the movement amount vector (dx, dy) to the origin (XD0, YD0) of the display screen coordinate system to move the origin of the display screen coordinate system. The origin of the display coordinate system after the movement is (XD0, YD0) = (XD0 + dx, YD0 + dy). However, in the first embodiment, it is assumed that the display screen coordinate system, the position input coordinate system, and the reference coordinate system have the same scale. When the scales of these coordinate systems are different from each other, the control unit 11 converts the movement amount vector obtained by the position input coordinate system into the scale of the display screen coordinate system and then adds it to the origin of the display screen coordinate system. To do.

  The area division of the touch panel 2 is not limited to the example shown in FIG. 4, but can be arbitrarily set by the designer of the display screen origin moving program.

  In the first embodiment, when the slide movement after pressing the mode change button 3 is in the −Y axis direction, the control unit 11 sets the movement amount vector to (dx) regardless of the touch start coordinate area. , Dy) = (XT−XS, YT−YS). However, the present invention is not limited to this, and when the slide movement is in the −Y-axis direction, the movement amount vector is determined so that the movement amount in the −Y-axis direction increases as the touch start coordinate is in the upper region. May be. This is because, when the slide movement is in the upward direction on the screen (−Y-axis direction), the reachable range of the finger with respect to the lower area becomes narrower as the touch start coordinates are in the upper area. That is, the control unit 11 may increase the amount of movement of the display screen in the slide movement direction as the reachable range of the finger in the direction opposite to the slide movement direction is narrower.

  FIG. 5 is a diagram illustrating an example of the hierarchical structure of the software group of the mobile terminal 1. In the application layer, applications that are actually operated by the user are classified. In the framework layer, software for managing the flow from the start to the end of the application is classified. The driver layer is a collection of drivers for each hardware. The driver layer includes a driver for the touch panel 103 and a driver for the mode change button 3.

  A display screen origin movement program corresponding to the control unit 11 is implemented in, for example, a driver layer. As a result, the display screen origin moving program can be started by pressing the mode change button 3 while any application is running without changing the processing of the application or the like.

(Process flow)
6A and 6B are examples of a flowchart of the origin movement process of the display screen coordinate system. The flowcharts shown in FIGS. 6A and 6B are started by detecting pressing of the mode change button 3. The pressing of the mode change button 3 is detected by the button operation detection unit 14 and notified to the control unit 11.

  In OP1, the control unit 11 initializes the origin of the display screen coordinate system and the position input coordinate system. In the first embodiment, since the third coordinate system having a fixed origin is used as the reference coordinate system, the origin (XD0, YD0) of the display screen coordinate system = the origin (XI0, YI0) of the position input coordinate system. = The origin (0, 0) of the reference coordinate system. Next, the process proceeds to OP2.

  In OP2, whether or not a touch on the touch panel 103 is detected is determined. If a touch on the touch panel 103 is detected (OP2: YES), the process proceeds to OP3. If no touch is detected on the touch panel 103 (OP2: NO), the process proceeds to OP9. Touch detection on the touch panel 103 is determined by inputting touch coordinates from the position input unit 12 to the control unit 11 within a predetermined time from detection of pressing of the mode change button 3. The predetermined time is, for example, less than 1 second.

  In OP3, the control unit 11 stores the touch coordinates detected in OP2 in the storage area (memory or buffer, not shown) of the RAM 102b as touch start coordinates (XS, YS). Next, the process proceeds to OP4.

In OP4, it is determined whether or not slide movement on the touch panel 103 has been detected. If slide movement is detected (OP4: YES), the process proceeds to OP5. If slide movement is not detected (OP4: NO), the process proceeds to OP9. Detection of slide movement
This is detected when the touch coordinates continuously input from the position input unit 12 to the control unit 11 at the scan interval of the touch panel 103 are moved by a predetermined distance or more.

  In OP5, the control unit 11 stores in the memory the touch coordinates during the slide movement input from the position input unit 12. Next, the process proceeds to OP6. Note that the touch coordinates stored in OP5 are, for example, the latest touch coordinates at the predetermined timing when the control unit 11 performs the next OP6 processing among the touch coordinates input from the position input unit 12 at the scan interval of the touch panel 103. Coordinates. However, it is not limited to this. For example, any touch coordinate input within a predetermined timing interval may be used.

  In OP6, the control unit 11 calculates the movement amount vector (dx, dy) of the origin of the display screen coordinate system. A flowchart for calculating the movement amount vector will be described later with reference to FIG. Next, the process proceeds to OP7.

  In OP7, the control unit 11 adds the calculated movement amount vector to the origin of the display screen coordinate system. The origin (XD0, YD0) = (XD0, YD0) + (dx, dy) = (XD0 + dx, YD0 + dy) of the display screen coordinate system. Next, the process proceeds to OP8.

  In OP8, the control unit 11 notifies the display processing unit 13 of the origin of the display screen coordinate system after the movement, and the display processing unit 13 updates the display screen according to the origin. Next, the process proceeds to OP9.

  In OP9, it is determined whether or not the mode change button 3 has been pushed up. The push-up of the mode change button 3 is detected by the button operation detection unit 14 and notified to the control unit 11. When the push-up of the mode change button 3 is detected (OP9: YES), the process proceeds to OP10. When the push-up of the mode change button 3 is not detected (OP9: NO), the process returns to OP3, and while the slide movement is detected, the process of OP3-OP8 is executed and displayed according to the slide movement of the user's finger. The screen moves.

  In OP10, the control unit 11 updates the origin (XI0, YI0) of the position input coordinate system held in the origin holding unit 15 to the origin (XD0, YD0) of the display screen coordinate system. When the process of OP10 is completed, the process illustrated in FIG. 6B ends.

After the mode change button 3 is pressed, slide movement is detected (OP4: YES), and when the origin of the display screen coordinate system is moved (OP5-OP7), the origin of the position input coordinate system is also moved. Become. After the origin of the display screen coordinate system is moved, the touch panel 103 can be operated in the same manner as before the origin of the display screen coordinate system is moved.

  When the origin movement of the display screen coordinate system is reset by depressing and pushing the mode change button 3 after the origin movement of the display screen coordinate system, the following processing is performed. First, when the mode change button 3 is pressed, the flowchart of FIG. 6A is started. In OP1, the origins of the display screen coordinate system and the position input coordinate system are initialized. Next, in OP2, the process proceeds to OP9 without detecting a touch, and in OP9, the push of the mode change button is detected, and the origin (0 of the display screen coordinate system and the position input coordinate system initialized in OP10). , 0) is saved.

  FIG. 7 is an example of a flowchart of the calculation processing of the movement amount vector of the origin of the display screen coordinate system. The flowchart shown in FIG. 7 corresponds to the process of OP6 in FIG. 6A.

In OP61, it is determined whether or not the detected slide movement direction is a downward movement of the screen. More specifically, the control unit 11 determines whether or not YT−YS> 0.
If the detected slide movement direction is a downward movement on the screen (OP61: YES), the process proceeds to OP62. If the detected slide movement direction is not a downward movement of the screen (OP61: NO), the process proceeds to OP64. Note that the slide movement direction that is not the downward movement of the screen is, for example, the upward movement of the screen.

  In OP62, the control unit 11 determines whether or not the touch start coordinates (XS, YS) are within the region C. If the touch start coordinates (XS, YS) are within the region C (OP62: YES), the process proceeds to OP66. In OP66, the control unit 11 obtains the movement amount vector (dx, dy) = (XT−XS, (YT−YS) × 3). Thereafter, the process proceeds to OP7 in FIG. 6B. If the touch start coordinates (XS, YS) are not within the region C (OP62: NO), the process proceeds to OP63.

  In OP63, the control unit 11 determines whether or not the touch start coordinates (XS, YS) are within the region B. If the touch start coordinates (XS, YS) are within the region B (OP63: YES), the process proceeds to OP65. In OP65, the control unit 11 calculates a movement amount vector (dx, dy) = (XT−XS, (YT−YS) × 2). Thereafter, the process proceeds to OP7 in FIG. 6B.

  If the touch start coordinates (XS, YS) are not in the area C or the area B (OP63: NO), that is, if the touch start coordinates (XS, YS) are in the area A, the process is OP64. Proceed to In OP64, the control unit 11 obtains a movement amount vector (dx, dy) = (XT−XS, YT−YS). Thereafter, the process proceeds to OP7 in FIG. 6B.

  As described above, when the slide movement after pressing the mode change button 3 is in the downward direction on the screen, the magnitude of the movement amount vector is determined by the area where the touch start coordinates are located. When the slide movement after the mode change button 3 is pressed is in the upward direction on the screen, a movement amount vector having the same magnitude as the slide movement vector is calculated.

(Screen transition example)
8A, 8B, and 8C are diagrams illustrating display screen examples of the mobile terminal 1 before and after the origin movement process of the display screen coordinate system. 8A, FIG. 8B, and FIG. 8C all show a display screen before the origin screen moving process of the display screen coordinate system on the upper side and a display screen after the origin moving process of the display screen coordinate system on the lower side.

  FIG. 8A is a diagram illustrating a display screen example of the portable terminal 1 before and after the origin movement process of the display screen coordinate system when the area A has touch start coordinates. When the touch start coordinates are present in the area A, it is determined that the mobile terminal 1 is held up one hand, and the movement amount vector at the origin of the display screen coordinate system is the same as the slide movement vector. That is, when viewed from the user, the display screen moves following the slide movement of the thumb.

  FIG. 8B is a diagram illustrating a display screen example of the portable terminal 1 before and after the origin movement process of the display screen coordinate system when the region B has touch start coordinates. If there is a touch start coordinate in the area B, it is determined that the middle of the mobile terminal 1 is held by one hand, and the Y component of the movement amount vector at the origin of the display screen coordinate system is twice the slide movement vector. Become. That is, when viewed from the user, the display screen moves twice as much as the sliding movement of the thumb.

FIG. 8C is a diagram illustrating a display screen example of the portable terminal 1 before and after the origin movement process of the display screen coordinate system when the region C has the touch start coordinates. If there is a touch start coordinate in the area C, it is determined that the user is holding the lower part of the mobile terminal 1 and the movement amount vector at the origin of the display screen coordinate system is three times the slide movement vector. That is, when viewed from the user, the display screen moves three times as much as the thumb slide movement.

  For example, in FIG. 8C, the user holds the lower part of the portable terminal 1 with one hand, and the icon located at the upper left of the screen is out of reach of the thumb. When the user presses the mode change button 3 and slides the thumb of the right hand downward, the display screen moves to the lower right, and the icon located at the upper left of the screen comes within the reach of the thumb of the right hand. . Thereby, the user can continue the operation on the touch panel 103 without holding the mobile terminal 1.

  Therefore, from FIG. 8A to FIG. 8C, the area of the start position of the downward slide movement is such that the smaller the reachable range of the finger in the upward direction of the screen, the larger the amount of downward movement of the screen. It can be in the reachable range of the finger.

<Operational effects of the first embodiment>
In the first embodiment, when the mobile terminal 1 detects a slide movement on the touch panel 103 when the mode change button 3 is pressed, the mobile terminal 1 moves the origin of the display screen coordinate system in the direction of the slide movement, and displays the display screen. Move. Accordingly, when the user holds the mobile terminal 1 with one hand, the user can continue the operation input to the touch panel 103 without holding the mobile terminal 1 or switching to the two-hand operation. Even when a larger touch panel is provided, the operability is improved. In addition, since the display screen moves in the direction of finger slide movement, the operation is intuitive and easy for the user to understand.

  Further, since the area of the start position of the slide movement after pressing the mode change button 3 is upper, middle, and lower, the magnitude of the movement amount vector of the origin of the display screen coordinate system is determined, so that the stress is further increased. Therefore, the operation target can be moved to the reachable range of the finger.

  Moreover, the display screen origin movement program can be executed in all applications and screens executed in the portable terminal 1 without being changed by being mounted in the driver layer.

  In the first embodiment, when the slide movement is in the downward direction on the screen, the movement amount of the Y component at the origin of the display screen coordinate system is changed. However, the present invention is not limited to this. For example, the slide movement is in the upward direction on the screen. Also in this case, the movement amount of the Y component at the origin of the display screen coordinate system may be changed. When the slide movement is in the upward direction on the screen, for example, the higher the slide start position is, the larger the movement amount of the origin of the display screen coordinate system in the upward direction is determined.

  Moreover, in 1st Embodiment, the portable terminal 1 is provided with the mode change button 3, and when the mode change button 3 is pressed, a display screen origin movement program starts. Instead of the mode change button 3, for example, the display screen origin movement program may be activated in response to an operation on an icon that is constantly displayed on the display.
