In the embodiment, an example in which the present invention is applied to a mobile phone will be described, but the present invention can also be applied to an information processing terminal such as a PDA or a PC other than the mobile phone.

  First, the external configuration of the mobile phone according to the present embodiment will be described with reference to FIG.

  The mobile phone according to the present embodiment includes a display unit 13, a key input operation unit 14, and a pointing operation unit 15. The pointing operation unit 15 includes a pointing device 16 that can instruct selection of items displayed on the display unit 13 and scrolling of the screen displayed on the display unit 13 when the user presses and rotates. ing.

  Next, the internal configuration of the mobile phone according to the present embodiment will be described with reference to FIG.

  The mobile phone according to the present embodiment includes an antenna 17, a high-frequency circuit unit 18 connected to the antenna 17, and a CPU 11 as a control unit for various functions. A display unit 13, a memory unit 12, a key operation input unit 14, a pointing operation unit 15, and an audio circuit unit 19 are connected to the CPU 11. The pointing operation unit 15 outputs a voltage signal corresponding to the pressing force, the pressing position, and the pressing direction to the CPU 11 by the operation of the pointing device 16 by the user. The CPU 11 includes an AD conversion circuit 22 and can read a voltage signal from the pointing operation unit 15. The CPU 11 controls each unit according to a control program stored in the memory unit 12. A speaker 20 and a receiver 21 are connected to the audio circuit unit 19.

  Next, an example of movement when the pointing device 16 included in the pointing operation unit 15 is operated will be described with reference to FIGS. In the figure, a circle indicates the position of the pointing device 16. The pointing operation unit 15 generates a signal indicating a movement destination two-dimensional coordinate component (X, Y) based on the movement of the pointing device 16. Note that the pointing device 16 returns to the origin (0, 0) after the user operates the pointing device 16. Further, the radius that the pointing device 16 can move is within the circumference of the maximum radius Rmax.

  Next, an operation for starting or stopping the scrolling mode using the pointing device 16 will be described with reference to FIG.

  First, the CPU 11 waits for an operation of the pointing device 16 by the pointing operation unit 15. When the pointing device 16 is operated, the CPU 11 receives a signal from the pointing operation unit 15, reads out from the memory unit 12 a control program related to a pointing mode for executing a function corresponding to the signal, and executes the control program (step S601). . A typical example of the pointing mode is an operation with a neuropointer mounted on a NEC mobile phone. When the control program related to the pointing mode is executed, the pointing operation unit 15 generates a two-dimensional coordinate component (X, Y) of the movement destination of the pointing device 16 at regular time intervals. When the CPU 11 determines that the position (X, Y) generated by the pointing operation unit 15 is outside the circumference of the reference radius Ra, the CPU 11 registers the position (X, Y) as the reference position (Xa, Ya). . The registration of the reference position (Xa, Ya) is performed by registering the position vector (Xa, Ya) of the reference position with the origin (0, 0) as the base point and the position of the pointing device 16 with the origin (0, 0) as the base point. The absolute value of the angle θ formed with the vector (X, Y) is held until it becomes larger than the reference angle θa.

  When the pointing device 16 is operated and a control program related to the pointing mode is executed, a pointer icon is displayed on the display unit 13. The pointer icon moves in the display unit 13 in a direction and speed according to the position vector (X, Y) of the movement destination of the pointing device 16, and the user can operate the cellular phone by a selection operation using the pointer icon. It becomes.

  Next, a flag L indicating whether the position (X, Y) of the moved pointing device 16 is inside or outside the circumference of the reference radius Ra is reset to L = 0 (step S602). . Next, it is determined by (X * X + Y * Y> Ra * Ra) whether or not the position (X, Y) of the pointing device 16 is outside the circumference of the reference radius Ra (step S603). Then, as shown in FIG. 3, when the position (X, Y) of the pointing device 16 is outside the circumference of the reference radius Ra (step S603 / YES), it is determined whether or not the flag L = 0 (step S603 / YES). Step S604).

  When the flag L = 0 (step S604 / YES), the position (X, Y) of the pointing device 16 at that time is registered as the reference position (Xa, Ya) (step S605). Further, the flag L is set to L = 1 (step S606). The reference position (Xa, Ya) is a position when the moving destination of the pointing device 16 goes out of the circumference of the reference radius Ra. On the other hand, when the flag L = 1 (step S604 / NO), the reference position (Xa, Ya) is not changed.

  Next, the position vector (Xa, Ya) of the reference position with the origin (0, 0) as the base point and the position vector (X, Y) of the position of the pointing device 16 with the origin (0, 0) as the base point The formed angle θ (movement angle) is calculated (step S607). Then, it is determined whether or not the calculated absolute value of the movement angle θ is larger than the reference angle θa (step S608). When the movement angle θ is larger than the reference angle θa (| θ |> θa) (step S608 / YES), the process shifts to the scrolling mode (step S609). Specifically, for example, as shown in FIG. 4, the pointing device 16 moves while maintaining a distance from the origin Ra or more, and the scrolling mode is started when the movement angle θ exceeds the reference angle θa. .

  In the scrolling mode, the pointer icon is erased from the display unit 13, and the angular velocity ω by the movement of the position vector indicating the position of the pointing device 16 with respect to the origin (0, 0) is calculated at regular intervals. Each function is operated by calculating the feed amount in proportion to the angular velocity ω. For example, as shown in FIG. 5, when the pointing device 16 is moved from the position (X1, Y1) to the position (X2, Y2), the position vector (X1, Y1) with the origin (0, 0) as the base point And an angular velocity ω that is a temporal change amount of an angle formed by the position vector (X2, Y2). When the angular velocity ω is calculated, the CPU 11 calculates and operates a feed amount proportional to the angular velocity ω in each function. The CPU 11 calculates the angular velocity ω at regular intervals, calculates a feed amount proportional to the angular velocity ω, and executes the scrolling mode by repeating the operation according to the feed amount. As an operation example of a function that operates using the angular velocity ω, for example, in the case of a browser function, scrolling of lines in proportion to the angular velocity ω is performed on a page that is long in the vertical direction. In the case of a player function for reproducing multimedia or the like, fast forward and rewind are performed in an amount proportional to the angular velocity ω. In the camera function, the zoom magnification is changed in proportion to the angular velocity ω.

  In the above description, the position vector (Xa, Ya) of the reference position with the origin (0, 0) as the base point and the position vector (X of the position of the pointing device 16 with the origin (0, 0) as the base point. , Y), whether or not the scrolling mode is started / stopped is determined by determining whether or not the absolute value of the angle θ formed by Y, Y) is larger than the reference angle θa. Further, when the scrolling mode is activated, each function is operated using an angular velocity ω obtained by moving a position vector indicating the position of the pointing device 16 with the origin (0, 0) as a base point. However, it is also possible to control the activation of the scrolling mode and the operation of each function based on the amount of movement of the pointing device 16 (for example, the locus from the reference position, the linear distance between the reference position and the current position, etc.). For example, as shown in FIG. 7, the moving distance from the position (X1, Y1) to the position (X2, Y2) is calculated, and it is determined whether or not the moving distance l is larger than a preset reference distance la. To determine whether to start / stop the scrolling mode. When the moving distance l is larger than the reference distance la, the scrolling mode is activated, and each function can be operated using the moving distance for every fixed time by the movement of the pointing device 16. Further, as shown in FIG. 8, the linear distance between the position (X1, Y1) and the position (X2, Y2) is calculated, and it is determined whether or not the linear distance l is larger than a preset reference distance la. Determine whether to start / stop the scrolling mode. When the linear distance l is greater than the reference distance la, the scrolling mode is activated, and the linear distance between the position (X1, Y1) and the position (X2, Y2) at regular intervals that changes as the pointing device 16 moves. It is also possible to operate each function using.

  In the scrolling mode, the CPU 11 determines whether or not the position (X, Y) of the pointing device 16 generated in the pointing operation unit 15 is within the circumference of the reference radius Rs (shown in FIG. 5) (X * X + Y * Y <Rs * Rs) is monitored (step S610). When the position (X, Y) of the pointing device 16 is maintained at a position outside the circumference of the reference radius Rs (step S610 / NO), the CPU 11 continues the scrolling mode. On the other hand, when the position (X, Y) of the pointing device 16 falls within the reference radius Rs (step S610 / YES), it is determined whether the pointing device 16 has returned to the origin (0, 0) and stopped. (Step S611). Here, the reference radius Rs used as the reference for ending the scrolling mode is made smaller than the reference radius Ra used as the reference for starting the scrolling mode. This is to facilitate the maintenance of the crawling mode.

  When the pointing device 16 has returned to the origin (0, 0) and stopped (step S611 / YES), the CPU 11 ends the control program related to the pointing mode and ends the operation of the pointing operation unit 15. On the other hand, when the pointing device 16 has not returned to the origin (0, 0) (step S611 / NO), the control program related to the pointing mode is continuously started and an operation by the pointing device 16 is accepted.

  According to the above-described configuration, the angular velocity is calculated from the circular motion of the pointing device, and the feed motion (scrolling mode) proportional to the angular velocity is performed in each function, so that the fine feed amount / scroll amount using the pointing device. Can be adjusted.

  Further, a reference radius Ra for determining the transition to the standby state waiting for the execution of the scrolling mode, a reference radius Rs for determining the end of the standby state waiting for the execution of the scrolling mode, and a reference angle for determining the execution of the scrolling mode θa is set as a threshold value, and it operates as a pointing mode in an initial state, the position of the pointing device moves outside the circumference of the reference radius Ra, and the pointing device is a reference angle from the position with respect to the origin (0, 0). When it moves more than θa, it shifts to the scrolling mode. When the position of the pointing device moves within the circumference of the reference radius Rs, the scrolling mode ends and the user returns to the pointing mode, so that the user can operate the pointing device. Both modes can be used easily and each mode The mobile phone can be operated in a mode suitable for the usage scene without being conscious of the switch to.

  Next, the configuration and operation of a mobile phone according to another embodiment will be described. In the above-described embodiment, an example using a joystick-type pointing device is used, but a configuration using a touch panel, a track pad, and a track ball may be used instead. In that case, when the center of the touch panel is set as the origin, the maximum radius Rmax is added to the reference threshold value, and the touched position moves outside the circumference of the reference radius Ra and within a circumference of the maximum radius Rmax by a circle more than the reference angle θa. When the mode is changed to the scrolling mode and the point position moves within the circumference of the reference radius Rs or outside the circumference of the maximum radius Rmax, or when the touch operation is finished, the scrolling mode is finished.

  FIG. 9 shows an external view of the mobile phone according to the present embodiment. The mobile phone according to the present embodiment includes a key input operation unit 14 and a touch panel operation unit 23. The touch panel operation unit 23 operates as a display unit, and has a touch panel function that allows a user to instruct selection of a displayed item and scroll the displayed screen by tracing the panel.

  FIG. 10 shows an internal configuration of the mobile phone according to the present embodiment. The mobile phone according to the present embodiment includes an antenna 17, a high-frequency circuit unit 18 connected to the antenna 17, and a CPU 11 as a control unit for various functions. The CPU 11 is connected to the memory unit 12, the key operation input unit 14, the touch panel operation unit 23, and the audio circuit unit 19. The touch panel operation unit 23 operates as a display unit and outputs a voltage signal corresponding to the contact position to the CPU 11 by a contact operation by the user. Further, the CPU 11 includes an AD conversion circuit 22 and can read a voltage signal from the touch panel operation unit 23. The CPU 11 controls each unit according to a control program stored in the memory unit 12. A speaker 20 and a receiver 21 are connected to the audio circuit unit 19.

  Next, an example of movement when the touch panel operation unit 23 is touched will be described with reference to FIGS. In the figure, a circle indicates a position touched by the user. The touch panel operation unit 23 generates a signal indicating the destination two-dimensional coordinate component (X, Y) based on the movement of the position touched by the user. Further, the user can operate the mobile phone wherever the touch panel operation unit 23 is touched.

  Next, an operation of starting or stopping the scrolling mode using the touch panel operation unit 23 will be described with reference to FIG.

  First, the CPU 11 waits for a touch operation by the user to the touch panel operation unit 23. When contact with the touch panel operation unit 23 is detected, the CPU 11 receives a signal from the touch panel operation unit 23, reads a control program related to the touch panel mode for executing a function corresponding to the signal from the memory unit 12, and executes it. (Step S1401).

  When the touch panel operation unit 23 is operated and a control program related to the touch panel mode is executed, the user can operate the mobile phone by a selection operation by a touch operation on the touch panel operation unit 23 or the like. When the control program related to the pointing mode is executed, the pointing operation unit 15 generates a two-dimensional coordinate component (X, Y) of the movement destination of the pointing device 16 at regular time intervals. When the CPU 11 determines that the position (X, Y) generated by the pointing operation unit 15 is outside the circumference of the reference radius Ra, the CPU 11 registers the position (X, Y) as the reference position (Xa, Ya). . The registration of the reference position (Xa, Ya) is performed by registering the position vector (Xa, Ya) of the reference position with the origin (0, 0) as the base point and the position of the pointing device 16 with the origin (0, 0) as the base point. The absolute value of the angle θ formed with the vector (X, Y) is held until it becomes larger than the reference angle θa.

  Next, a flag L indicating whether the contact position (X, Y) of the user is inside or outside the circumference of the reference radius Ra is reset to L = 0 (step S1402). Next, the contact position (X, Y) is outside the circumference of the reference radius Ra (X * X + Y * Y> Ra * Ra) and within the circumference of the maximum radius Rmax (X * X + Y * Y <Rmax) * Rmax) is determined (step S1403). As shown in FIG. 11, when the contact position (X, Y) is outside the circumference of the reference radius Ra and within the circumference of the maximum radius Rmax (step S1403 / YES), whether or not the flag L = 0 is set. Is determined (step S1404).

  When the flag L = 0 (step S1404 / YES), the contact position (X, Y) at that time is registered as the reference position (Xa, Ya) (step S1405). Further, the flag L is set to L = 1 (step S1406). The reference position (Xa, Ya) is a position when the moving destination of the contact position goes outside from the circumference of the reference radius Ra. On the other hand, when the flag L = 1 (step S1404 / NO), the reference position (Xa, Ya) is not changed.

  Next, the angle θ formed by the position vector (Xa, Ya) of the reference position with the origin (0, 0) as the base point and the position vector (X, Y) of the contact position with the origin (0, 0) as the base point (Moving angle) is calculated (step S1407). Then, it is determined whether or not the calculated absolute value of the movement angle θ is larger than the reference angle θa (step S1408). When the movement angle θ is larger than the reference angle θa (| θ |> θa) (step S1408 / YES), the process shifts to the scrolling mode (step S1409). Specifically, for example, as shown in FIG. 12, the scrolling mode is started when the contact position moves with the distance from the origin maintained at Ra or more and the movement angle θ exceeds the reference angle θa.

  In the scrolling mode, the angular velocity ω by the movement of the position vector indicating the contact position with the origin (0, 0) as the base point is calculated at regular intervals, and the feed amount is calculated in proportion to the calculated angular velocity ω. Activate each function. For example, as shown in FIG. 13, when the contact position is moved from the reference position (X1, Y1) to the position (X2, Y2), the position vector (X1, Y1) with the origin (0, 0) as the base point And an angular velocity ω that is a temporal change amount of an angle formed by the position vector (X2, Y2). When the angular velocity ω is calculated, the CPU 11 calculates and operates a feed amount proportional to the angular velocity ω in each function. The CPU 11 calculates the angular velocity ω at regular intervals, calculates a feed amount proportional to the angular velocity ω, and executes the scrolling mode by repeating the operation according to the feed amount. As an operation example of a function that operates using the angular velocity ω, for example, in the case of a browser function, scrolling of lines in proportion to the angular velocity ω is performed on a page that is long in the vertical direction. In the case of a player function for reproducing multimedia or the like, fast forward and rewind are performed in an amount proportional to the angular velocity ω. In the camera function, the zoom magnification is changed in proportion to the angular velocity ω.

  In the above description, the position vector (Xa, Ya) of the reference position with the origin (0, 0) as the base point and the position vector (X, Y) of the contact position with the origin (0, 0) as the base point. The starting / stopping of the scrolling mode is determined by determining whether or not the absolute value of the angle θ formed by is larger than the reference angle θa. Furthermore, when starting the scrolling mode, each function was operated using the angular velocity ω by the movement of the position vector indicating the contact position with the origin (0, 0) as the base point. However, it is also possible to control the activation of the scrolling mode and the operation of each function based on the movement amount of the contact position (for example, the locus from the reference position, the linear distance between the reference position and the current position, etc.). For example, as shown in FIG. 15, the movement distance from the reference position (X1, Y1) to the position (X2, Y2) is calculated, and whether or not the movement distance l is larger than a preset reference distance la. Based on the determination, the start / stop of the scrolling mode is determined. When the movement distance l is larger than the reference distance la, the scrolling mode is activated, and each function can be operated using the movement distance at regular intervals by the movement of the contact position. Further, as shown in FIG. 16, a straight line distance between the reference position (X1, Y1) and the position (X2, Y2) is calculated, and it is determined whether or not the straight line distance l is larger than a preset reference distance la. To determine whether to start / stop the scrolling mode. When the straight line distance l is larger than the reference distance la, the scrolling mode is activated, and the straight line distance between the position (X1, Y1) and the position (X2, Y2) at regular intervals that changes due to the movement of the contact position is calculated. It is also possible to operate each function by using it.

  In the scrolling mode, the CPU 11 determines that the contact position (X, Y) generated in the touch panel operation unit 23 is within the circumference of the reference radius Rs (shown in FIG. 13) (X * X + Y * Y <Rs * Rs). ) Or outside the circumference (X * X + Y * Y> Rmax * Rmax) where the contact position (X, Y) is the maximum radius Rmax is monitored (step S1410). When the contact position (X, Y) remains at a position outside the circumference of the reference radius Rs and within the circumference of the maximum radius Rmax (step S1410 / NO), the CPU 11 continues the scrolling mode. On the other hand, when the contact position (X, Y) falls within the reference radius Rs or when the contact position (X, Y) falls outside the maximum radius Rmax (step S1410 / YES), it is determined whether or not there is a contact position. Judgment is made (step S1411). Here, the reference radius Rs used as the reference for ending the scrolling mode is made smaller than the reference radius Ra used as the reference for starting the scrolling mode. This is to facilitate the maintenance of the crawling mode.

  When there is no contact position (step S1411 / YES), CPU11 complete | finishes the control program which concerns on a touchscreen mode, and complete | finishes operation of the touchscreen operation part 23. FIG. On the other hand, if there is a contact position (step S1411 / NO), the control program related to the touch panel mode is continuously started and an operation by the touch panel operation unit 23 is accepted.

  According to the above-described configuration, the angular velocity is calculated from the circular motion on the touch panel, and the feed operation (scrolling mode) proportional to the angular velocity is performed in each function, so that the fine feed amount / scroll amount using the touch panel. Can be adjusted.

  Further, a reference radius Ra for determining the transition to the standby state waiting for the execution of the scrolling mode, a reference radius Rs for determining the end of the standby state waiting for the execution of the scrolling mode, and a reference angle for determining the execution of the scrolling mode θa is set as a threshold value, and it operates as a touch panel mode in the initial state, the contact position moves outside the circumference of the reference radius Ra and within the circumference of the maximum radius Rmax, and the contact position is based on the origin (0, 0). When the position moves from the position to the reference angle θa or more, the mode shifts to the scrolling mode. When the contact position moves within the circumference of the reference radius Rs or outside the circumference of the maximum radius Rmax, the scrolling mode is terminated, and the touch panel By returning to the mode, the user can easily use both modes by touch operation and is aware of switching to each mode. Thus, the mobile phone can be operated in a mode suitable for the usage scene.
