Description

  The present invention relates to a coordinate input device capable of performing a click operation.

  In recent years, in various electronic devices such as a PC (personal computer), a mouse, a touch pad, a tablet, or the like has been put to practical use as a pointing device for moving a cursor on a screen. For example, the mouse is usually provided with a click key.

  Since the click key is provided on the mouse, the user using the mouse not only moves the cursor but also causes the electronic device to execute the program indicated by the icon by clicking the click key on the icon. Is possible. At this time, the electronic device considers that one input is made by one click. For example, in the case of a tablet, when the pen touches the tablet or is lightly pressed, the electronic device can execute the program indicated by the icon.

  Here, there are cases where one input is regarded as being made by one click and cases where it is regarded as being made by two clicks (double click). In the case of double-clicking, in order for this operation to be recognized by the electronic device, the user needs to click approximately the same position twice within a predetermined time.

  However, if the clicked position is not clicked twice within a certain time or if the first pressed position is shifted from the second pressed position, the electronic device does not recognize the double click, and one click is performed twice. It will be recognized that it was done. In particular, in a tablet or the like that is input using a pen, the pressing position is likely to shift.

  Therefore, Patent Documents 1 to 3 disclose techniques for making the electronic device easy to recognize double clicks.

  Specifically, in the technique of Patent Document 1, an allowable value between a time difference and a position shift when double-clicking is stored in advance, and the time difference between the first press and the second press and the shift of the press position are described above. Determine if it is within the tolerance. If it is determined that the value is within the allowable value, the first input coordinate value is output to the outside as the second input coordinate value. With this configuration, even a touch-type input panel that tends to cause a shift in the pressed position can easily recognize double-clicks.

  Further, in the technique of Patent Document 2, when a second press is performed within a predetermined time in the same data input area as the first press position, it is determined that a double click operation has been performed. Note that the second pressing position is not limited to the same data input area as the first pressing position, but is within a predetermined range in the X and Y axis directions from the data input area, or from the first pressing position. , And may be within a predetermined range in the Y-axis direction. With this configuration, even if the first input area is small, reliable and easy double-clicking is possible.

  Furthermore, the technique of Patent Document 2 has a function of causing the display unit to display a range determined to be double click. For this reason, it becomes possible to visually check the effective range of the double click, and the double click input can be performed more reliably and easily.

In the technique of Patent Document 3, the movement of the mouse is suppressed for a certain time after the first click of the mouse button. With this configuration, it is possible to reliably hold the mouse cursor on the target icon and reliably avoid or prevent the mouse cursor from being detached from the target icon before the second click operation.
Japanese Patent Laid-Open No. 9-325851 (released on December 16, 1997) Japanese Patent Laid-Open No. 10-143419 (published February 14, 1995) Japanese Patent Laid-Open No. 2001-5606 (released on January 12, 2001)

  However, in the techniques of Patent Documents 1 and 2, when the range of allowable values of time difference and positional deviation is exceeded, it is not recognized as a double click. That is, since the user needs to perform a double-click operation within the allowable value within a certain time, it becomes a device that is difficult for a user who is unfamiliar with the click operation.

  Further, in the technique of Patent Document 2, it is possible to display a range that can be pressed for the second time. However, since the range that can be pressed is limited, if the range is not sufficient for the user who performs the double-click operation, the device is also difficult to operate.

  Further, the techniques of Patent Documents 1 to 3 are techniques for facilitating a double click operation, and do not disclose a technique for causing the electronic device to easily recognize a single click operation. Note that the technique disclosed in Patent Document 3 suppresses the movement of the mouse after the first click, and does not suppress the movement during the first click.

  That is, in Patent Documents 1 to 3, the amount of movement during a single press using a finger, pen, or the like is detected at regular intervals. Therefore, when the amount of movement during one press is small and the click operation is completed within a certain time, the electronic device can be made to recognize this click operation as one click.

  However, when the amount of movement increases, the electronic device may not be able to recognize the click operation as a single click. In particular, in the case of a touch pad that can be pressed, it is difficult to recognize a click operation, and thus there is a high possibility that the amount of movement will increase. For this reason, the user must perform a click operation in consideration of not moving the finger. In addition, in the case of double-clicking, the click operation is further difficult to be recognized, so that the user uses considerable nerves.

  The present invention has been made in view of the above problems, and an object thereof is to provide a coordinate input device that allows a user to perform a click operation without being aware of the movement of a finger while the touch pad is being pressed. There is to do.

  In order to solve the above-described problem, a coordinate input device according to the present invention is a coordinate input device that integrally includes coordinate input means for inputting coordinates and a press input means for inputting a non-pressed state. When the pressing input means is in the non-pressed state, the coordinate input means determines a value indicating the amount of movement from the previously acquired coordinates as the output value, and when the pressing input means is in the pressed state. And an output value determining means for determining the output value to be 0 or a value in a range regarded as 0 in the receiving device, and a transmitting means for transmitting the output value determined by the output value determining means. It is characterized by.

  Further, in order to solve the above problems, the control method of the coordinate input device according to the present invention is a coordinate system integrally including coordinate input means for inputting coordinates and a press input means for inputting a non-pressed state. A method for controlling an input device, wherein when the pressing input unit is in a non-pressed state, a value indicating a movement amount from the previously acquired coordinate of the coordinate acquired this time by the coordinate input unit is determined as an output value, and When the pressing input means is in the pressed state, the output value is determined to be 0 or a value in a range that is considered to be 0 in the receiving device, and the output value determined by the output value determining means is transmitted. And a transmission step.

  According to the above configuration, since the coordinate input unit and the press input unit are integrally configured, the press input unit is pressed in conjunction with the press of the coordinate input unit. That is, the pressing input means for inputting the pressing non-pressing state shows the pressing non-pressing state of the coordinate input means. The output value determining means determines an output value to be transmitted to the transmitting means depending on whether the pressing input means is in the pressed state or not pressed. And a transmission means transmits the output value determined by the output value determination means to the apparatus by which a cursor is displayed, for example.

  Specifically, when the input means is in a non-pressed state, the output value determining means uses the value indicating the amount of movement from the previously acquired coordinates by the coordinate input means as the output value, and the press input means In the state, the output value is set to 0 or a value in a range considered as 0 in the receiving device.

  Here, the output value determining means determines not only a value of 0 but also a value in a range regarded as 0 in the receiving apparatus when the pressing input means is in the pressed state. This is because the range of the output value when the press input unit is in the pressed state may be a range in which the device receiving the output value, for example, the device on which the cursor is displayed can recognize the click or double click.

  As a result, the coordinate input device determines the output value to be 0 or a value in a range that is regarded as 0 in the receiving device when the press input unit is in the pressed state. The cursor position when the pressing is completed can be made the same. Therefore, the coordinate input device can cause the device on which the cursor is displayed, for example, to sufficiently recognize the user's click operation (including a double click operation). Then, the user can perform a click operation without being aware of the movement of the finger when the pressing input unit is in the pressed state.

  Furthermore, the coordinate input device according to the present invention may make the time interval for acquiring the coordinate input by the user by the coordinate input means longer than that in the non-pressed state when the press input means is in the pressed state. .

  Thereby, since the coordinate input device makes the time interval for acquiring the coordinate input by the user longer than in the non-pressed state, the output value determining unit is compared with the case of acquiring the coordinate input in the non-pressed state. In addition, the time during which processing in the transmission unit is stopped becomes longer. Accordingly, since the coordinate input device does not need to supply power to the output value determination unit and the transmission unit while the coordinate input device is stopped, the power consumption of the coordinate input device can be suppressed.

  As described above, the coordinate input device according to the present invention uses, as an output value, a value indicating the amount of movement from the previously acquired coordinates of the coordinates acquired this time by the coordinate input means when the press input means is in a non-pressed state. In addition, when the pressing input unit is in the pressed state, the output value is determined by the output value determining unit and the output value determining unit that determines the output value to be 0 or a value in a range regarded as 0 in the receiving device. And a transmission means for transmitting the output value.

  Further, the control method of the coordinate input device according to the present invention provides, as an output value, a value indicating a movement amount from the previously acquired coordinate of the coordinate acquired this time by the coordinate input unit when the pressed input unit is in a non-pressed state. And the output value determining step for determining the output value to be 0 or a value in the range considered to be 0 in the receiving device when the press input means is in the pressed state, and the output value determining means And a transmission step of transmitting the output value.

  Therefore, according to the configuration of the present invention, for example, the device on which the cursor is displayed can sufficiently recognize the user's click operation (including the double click operation), and the user can press the pressing input unit. Even so, there is an effect that the click operation can be performed without being aware of the movement of the finger.

Embodiment 1
An embodiment of the present invention will be described below with reference to FIGS.

[Outline of transmission / reception system example]
First, the outline of the present invention will be described with reference to FIG. FIG. 2 is an explanatory diagram showing an example of an outline of the transmission / reception system 1 of the present invention. As shown in FIG. 2, the transmission / reception system 1 includes a remote controller (coordinate input device) 2, a display device 3, and a PC main body 4. In the transmission / reception system 1, the remote controller 2 and the PC main body 4 perform transmission / reception with an RF (radio frequency) signal. In the transmission / reception system 1, the PC body 4 and the display device 3 are connected.

  The PC body 4 outputs the processing content based on the data transmitted from the remote controller 2 to the display device 3. The PC body 4 is provided with an RF transmission / reception unit 4a. Since the remote controller 2 is also provided with an RF transmission / reception unit (transmission means) 8 described later, for example, data from the remote controller 2 can be received.

  The display device 3 includes a display unit 3a, and displays contents based on the data transmitted from the PC main body 4 on the display unit 3a. For example, an icon, a cursor, and the like are displayed on the display unit 3a.

  The display device 3 may not only display the contents of data transmitted from the PC main body 4, but may have a TV function. In this case, the display device 3 can watch TV broadcast while operating the PC, and the remote controller 2 may directly control the display device 3.

  As shown in FIG. 2, the remote controller 2 includes a touch pad (coordinate input means) 5 and function keys 6 on the upper surface (the surface on the side on which the user of the remote controller 2 operates). In addition, the remote controller 2 includes an RF transmission / reception unit 8 on the surface facing the display device 3 when the normal remote controller 2 is operated.

  The touch pad 5 detects which position on the touch pad 5 is touched when a finger touches the surface (the surface exposed to the outside of the remote controller 2). Examples of the touch pad 5 include a capacitance type touch panel or a resistive touch panel. Here, the capacitive touch pad detects that the amount of internal charges changes when the finger touches the surface of the touch pad 5, thereby detecting the movement of the finger on the touch pad 5. Also, the resistive film type touch pad is a method in which a conductive thin film is pasted on the surface of the touch pad 5 and a film attached to the surface at a slight interval to detect whether or not electricity has passed through the thin film. To do.

  As described above, the remote controller 2 can perform coordinate input by touching the touch pad 5 with a finger, so that the PC main body 4 performs processing such as moving the cursor displayed on the display unit 3a of the display device 3, for example. Can be executed.

  As shown in FIG. 3, a push SW (switch) 7 is provided below the touch pad 5 (inside the remote controller 2). The touch pad 5 is movable in the direction of a push SW (press input means) 7, and the push SW 7 is pressed in conjunction with the touch pad 5 being pressed. That is, when the touch pad 5 is pressed, the push SW 7 is pressed. When the touch pad 5 is not pressed, the push SW 7 is not pressed. The pressing state of the push SW 7 is detected as pressing information A by an input key detection unit 22 described later.

  FIG. 3 is a diagram showing a schematic configuration of a cross section of the remote controller 2. FIG. 3A shows a state of the push SW 7 when the touch pad 5 is touched, and FIG. The state of the push SW 7 when the touch pad 5 is pressed is shown.

  As described above, in the remote controller 2, the user can perform coordinate input by placing a finger on the touch pad 5 and moving it, and can perform a click operation by pressing the touch pad 5.

  A function key 6 shown in FIG. 2 is for transmitting a specific operation command to the PC main body 4 when pressed by a user operating the remote controller 2. Examples of the operation command include an operation command for performing power on / off switching, a click operation, a drag operation, and the like of the PC main body 4. In addition, when the display device 3 has a TV function, switching of each channel such as TV broadcasting, switching of power on / off of the display device 3, switching of a PC screen and a TV screen, or setting of a timer, image quality, etc. The operation command for performing etc. is mentioned.

  Further, when receiving a transmission signal transmitted from a transmission signal generation unit (transmission means) 25 described later, the RF transmission / reception unit 8 converts this signal into an RF signal pattern and transmits it to the PC main body 4. Note that, when receiving an RF signal pattern from the PC main body 4, the RF transmission / reception unit 8 converts the RF signal pattern into a signal that can be processed by the remote controller 2.

  As shown in FIG. 4, the PC main body 4 includes an RF transmission / reception unit 4 a, a control unit 41, and a storage unit 42. FIG. 4 is a block diagram showing a schematic configuration of the PC main body 4.

  The control unit 41 processes the content of data transmitted from the remote controller 2 and transmits the processing result to the display device 3. For example, the control unit 41 determines the operation of the cursor by receiving a signal transmitted from the remote controller 2 and including a later-described output value and pressing information A. And the control part 41 displays a cursor on the display part 3a of the display apparatus 3 based on this determination.

  The storage unit 42 stores data and programs used by the control unit 41. For example, when the user performs a double-click operation in which the touch pad 5 is pressed twice in succession, the storage unit 42 stores the amount of movement of the cursor during the click and the double-click so that the control unit 41 can determine this operation. The allowable value and the click time interval allowable value when double-clicking are stored. And the control part 41 can determine whether the operation is a double click, when a user presses down the touchpad 5 twice by referring these values. The allowable range of time recognized as a double click by the PC main body 4 is defined by the time from the start of the first press to the start of the second press, for example.

[Remote control configuration]
Next, a more detailed configuration of the remote controller 2 will be described with reference to FIG. FIG. 1 is a block diagram showing a schematic configuration of the remote controller 2. As shown in the figure, the remote controller 2 includes a touch pad 5, a function key 6, a push SW 7, an RF transmitter / receiver 8, an input coordinate detector 21, an input key detector 22, an input key state determiner 23, an output value determiner (output). Value determination means) 24, a transmission signal generation unit 25, an input coordinate storage unit 26, and a touchpad state storage unit 27. Note that the description of the touch pad 5, the function key 6, the push SW 7, and the RF transmitting / receiving unit 8 described above is omitted.

  The input coordinate detection unit 21 detects a detection result on the touch pad 5 (a result of detecting which position on the touch pad 5 is touched), and input coordinates (x coordinate and y coordinate) from the detection result. Is calculated. The x coordinate calculated at this time is Xin, and the Y coordinate is Yin.

  The input coordinate detection unit 21 transmits the input coordinates (Xin, Yin) to the input coordinate storage unit 26, substitutes the input coordinates (Xin, Yin) for the input coordinates (Xpre, Ypre), and the input coordinate storage unit. 26 is stored. The input coordinate detection unit 21 does not perform this substitution operation when the input coordinates (Xin, Yin) are relative coordinates.

  Here, the input coordinate storage unit 26 stores a movement amount (0, 0). The movement amount (0, 0) may be set within a range in which the PC body 4 can recognize a click or a double click. That is, the movement amount stored in the input coordinate storage unit 26 may not be (0, 0), but may be a range that is regarded as (0, 0) in the PC body 4.

  The input key detection unit 22 detects whether or not the function key 6 and the push SW 7 are pressed, that is, information indicating the pressed state of the function key 6 and the push SW 7 (press information A). Then, the input key detection unit 22 transmits this press information A to the input key state determination unit 23.

  The input key state determination unit 23 determines whether the push SW 7 and each function key 6 are pressed, that is, which of the push SW 7 and each function key 6 is pressed based on the pressing information A transmitted from the input key detection unit 22. Determine. Further, the input key state determination unit 23 determines whether or not the push SW 7 is pressed, that is, whether or not the touch pad 5 is pressed in the determination on the pressing information A, and the pressed state of the touch pad 5 is used as a determination signal. It transmits to the output value determination part 24.

  Further, the input key state determination unit 23 determines whether the previous pressing state TCpre of the touch pad 5 (that is, the push SW 7) stored in the touch pad state storage unit 27 is on or off, and also determines the determination result. The signal is transmitted to the output value determination unit 24 as a signal. The input key state determination unit 23 turns on the pressed state TCpre stored in the touch pad state storage unit 27 using the pressed state of the touch pad 5 in the pressed information A transmitted from the input key detection unit 22. Or rewrite off.

  Further, the input key state determination unit 23 transmits the pressing information A transmitted from the input key detection unit 22 to the transmission signal generation unit 25.

  When the output value determining unit 24 detects the input coordinates (Xin, Yin) and the input coordinates (Xpre, Ypre), it calculates the movement amount (Xin-Xpre, Yin-Ypre) by subtracting these two input coordinates. To do. The output value determining unit 24 only detects the input coordinates (Xin, Yin) when the input coordinates (Xin, Yin) are relative coordinates. This is because the relative coordinates indicate the movement amount.

  When the output value determination unit 24 receives the determination signal from the input key state determination unit 23, the output value determination unit 24 determines the movement amount (Xin-Xpre, Yin-Ypre) and the movement amount (0, 0) based on the determination signal. Decide which output value to use. Then, the output value determination unit 24 transmits this output value to the transmission signal generation unit 25. When the input coordinates (Xin, Yin) are relative coordinates, the output value determination unit 24 determines which movement amount of the relative coordinates (Xin, Yin) and the relative coordinates (0, 0) is the output value. decide.

  The transmission signal generation unit 25 transmits the pressing information A received from the input key state determination unit 23 and the input coordinate data received from the output value determination unit 24 to the RF transmission / reception unit 8 as a transmission signal. The PC body 4 can control the operation of the cursor by the RF transceiver unit 8 converting the transmission signal into an RF signal and transmitting it to the PC body 4.

[Pointing operation processing on the remote control]
Next, the flow of processing in the remote controller 2 will be described. FIG. 5 is a flowchart showing the flow of the pointing operation process in the remote controller 2.

  First, when there is some change in the touch pad 5, the touch pad 5 detects which position on the touch pad 5 is touched. That is, the pointing process is started. At this time, the transmission signal generation unit 25 inquires of the input coordinate detection unit 21 about the current input coordinate (S1). The input coordinate detection unit 21 detects a detection result on the touch pad 5 (a result of detecting which position on the touch pad 5 is touched), and calculates an input coordinate from the detection result. The x coordinate calculated at this time is Xin, and the Y coordinate is Yin.

  Then, the input coordinate detection unit 21 transmits the input coordinates (Xin, Yin) to the input coordinate storage unit 26, and the input coordinates (Xin, Yin) transmitted from the input coordinate detection unit 21 are the previously detected input coordinates (Xin, Yin). Substituting into Xpre, Ypre) and storing it in the input coordinate storage unit 26 (S2). Thereafter, the input coordinate detection unit 21 further detects the current input coordinates (Xin, Yin) on the touch pad 5 (S3).

  At this time, when the output value determination unit 24 detects the input coordinates (Xin, Yin) from the input coordinate detection unit 21 and also detects the input coordinates (Xpre, Ypre) from the input coordinate storage unit 26, these two input coordinates Is subtracted to calculate the movement amount (Xin−Xpre, Yin−Ypre).

  Next, the input key state determination unit 23 inquires of the input key detection unit 22 about the pressing information A (S4). The pressing information A is information indicating whether or not the function key 6 and the push SW 7 are pressed. When receiving an inquiry about the pressing information A, the input key detecting unit 22 detects information (pressing information A) indicating whether or not the function key 6 and the push SW 7 are pressed. Then, the input key detection unit 22 transmits this press information A to the input key state determination unit 23.

  The input key state determination unit 23 determines whether or not the pressing information A means no input, that is, whether or not the pressing information A indicates that the function key 6 or the push SW 7 is pressed (S5).

  When the pressing information A means no input (does not indicate pressing of the function key 6 or the push SW 7) (YES in S5), the current pressing state of the touch pad 5 is not pressed (off). Is shown. At this time, the input key state determination unit 23 determines whether or not the previous pressing state (TCpre) of the touch pad 5 is pressed (S6).

  Here, in the touchpad state storage unit 27, when the previous pressing state (TCpre) of the touchpad 5 is pressed, the pressing state “TCpre = ON” is stored and pressed. If not, the pressed state “TCpre = off” is stored. The input key state determination unit 23 reads a TC on signal from the touch pad state storage unit 27 when the key is pressed and a TC off signal when the key is not pressed. Thereby, the input key state determination unit 23 determines whether the pressed state TCpre is on or off.

  When TCpre = off (NO in S6), the input key state determination unit 23 indicates a state where both the current pressing state and the pressing state TCpre of the touch pad are not pressed. Is transmitted to the output value determination unit 24. At this time, the input key state determination unit 23 transmits the function key 6 and push-down information A (current press state) on the push SW 7 to the transmission signal generation unit 25.

  When receiving the determination signal (TC off signal), the output value determining unit 24 determines the movement amount (Xin−Xpre, Yin−Ypre) calculated by the output value determining unit 24 as an output value. Then, the output value determination unit 24 transmits this output value to the transmission signal generation unit 25.

  The transmission signal generation unit 25 transmits the pressing information A received from the input key state determination unit 23 and the output value received from the output value determination unit 24 to the RF transmission / reception unit 8 as a transmission signal.

  Here, paying attention to the pressed state of the touch pad 5 (pressed state of the push SW 7), the pressed state of the touch pad 5 is transmitted using a left click signal that is a signal indicating the pressed state of the left click key. The determination signal received by the output value determination unit 24 from the input key state determination unit 23 is a TC off signal. Therefore, the transmission signal generation unit 25 transmits the left click signal (off signal) and the output value indicating the movement amount (Xin-Xpre, Yin-Ypre) to the RF transmission / reception unit 8 as a transmission signal. Then, the RF transceiver 8 converts this transmission signal into an RF signal and transmits it to the PC main body 4 (S7).

  Thereafter, the input coordinate detection unit 21 determines that Xin = Xpre and Yin based on the input coordinates (Xin, Yin) and the input coordinates (Xpre, Ypre) stored in the input coordinate detection unit 21 and the input coordinate storage unit 26. It is determined whether or not Ypre (S8). If YES in S8, the pointing process is terminated, and if NO, the process returns to S2.

  Further, when the pressing information A does not mean no input (indicating that the function key 6 or the push SW 7 is pressed) (NO in S5), the input key state determination unit 23 indicates that the pressing information A is the touch pad 5 It is determined whether or not pressing is indicated (S9).

  When the pressing information A indicates that the touch pad 5 is pressed (YES in S9), when the input key state determination unit 23 determines that the current pressing state of the touch pad 5 is on, a TC on signal is used as a determination signal. Is transmitted to the output value determination unit 24.

  When receiving the determination signal (TC on signal), the output value determination unit 24 determines the movement amount (0, 0) stored in the input coordinate storage unit 26 as an output value. Then, this output value is transmitted to the transmission signal generator 25. At this time, the input key state determination unit 23 rewrites the pressed state TCpre stored in the touchpad state storage unit 27 to ON. Then, the transmission signal generation unit 25 transmits the pressing information A received from the input key state determination unit 23 and the output value received from the output value determination unit 24 to the RF transmission / reception unit 8 as a transmission signal.

  Here, paying attention to the pressed state of the touch pad 5 (pressed state of the push SW 7), the determination signal received by the output value determination unit 24 from the input key state determination unit 23 is a TC-on signal, and thus the transmission signal generation unit 25. Transmits the left click signal (ON signal) and the output value indicating the movement amount (0, 0) to the RF transceiver 8 as a transmission signal. Then, the RF transceiver 8 converts this transmission signal into an RF signal and transmits it to the PC body 4 (S10). Thereafter, the process returns to S2.

  If TCpre = ON (YES in S6), the current pressing state of the touch pad 5 is OFF, but the previous pressing state TCpre of the touch pad 5 indicates ON. The determination unit 23 transmits a TC ON signal as a determination signal to the output value determination unit 24. At this time, the input key state determination unit 23 transmits the function key 6 and push-down information A (current press state) on the push SW 7 to the transmission signal generation unit 25.

  When receiving the determination signal (TC on signal), the output value determination unit 24 determines the movement amount (0, 0) stored in the input coordinate storage unit 26 as an output value. Then, this output value is transmitted to the transmission signal generator 25. At this time, the input key state determination unit 23 rewrites the pressed state TCpre stored in the touchpad state storage unit 27 to off.

  The transmission signal generation unit 25 transmits the pressing information A received from the input key state determination unit 23 and the output value received from the output value determination unit 24 to the RF transmission / reception unit 8 as a transmission signal.

  Here, paying attention to the pressed state of the touch pad 5 (pressed state of the push SW 7), the determination signal received by the output value determination unit 24 from the input key state determination unit 23 is a TC off signal, and thus the transmission signal generation unit 25. Transmits the left click signal (off signal) and the output value indicating the movement amount (0, 0) to the RF transceiver 8 as a transmission signal. Then, the RF transceiver 8 converts this transmission signal into an RF signal and transmits it to the PC main body 4 (S11). Thereafter, the process returns to S8.

  In the process of S11, the output value determination unit 24 determines the left click signal (off signal) and the movement amount (0, 0) as output values. As a result, an off signal is output as the left click signal to the PC main body 4, so that the PC main body 4 can recognize that the touch pad 5 has been pressed as the touch pad 5 is pressed. Further, even after the touch pad 5 is completely pressed, the movement amount (0, 0) is output as an output value to the PC main body 4, so that it is possible to suppress positional deviation when the user performs a double-click operation. .

  If the pressing information A does not indicate that the touch pad 5 is pressed (NO in S9), the input key state determination unit 23 determines that the previous pressing state TCpre of the touch pad 5 is off (S13).

  Next, when the pressing information A indicates the pressing of the left click key (YES in S13), the input key state determination unit 23 determines that the pressing state of the left click key is on, and LC is turned on as a determination signal. The signal is transmitted to the output value determining unit 24.

  When receiving the determination signal (LC ON signal), the output value determination unit 24 determines the movement amount (Xin−Xpre, Yin−Ypre) calculated by the output value determination unit 24 as an output value. Then, this output value is transmitted to the transmission signal generator 25.

  The transmission signal generation unit 25 transmits the pressing information A received from the input key state determination unit 23 and the output value received from the output value determination unit 24 to the RF transmission / reception unit 8 as a transmission signal. Then, the RF transceiver 8 converts this transmission signal into an RF signal and transmits it to the PC body 4 (S14). Thereafter, the process returns to S2.

  If the pressed information A does not indicate that the left click key is pressed (NO in S13), for example, the process enters when the right click key or the like is pressed (S15). This process is arbitrarily determined. Then, when the process of S15 ends, the process returns to S2.

  As described above, when the input key state determination unit 23 determines that the current pressing state of the touch pad 5 is on (the touch pad 5 is pressed), the output value determination unit 24 inputs The movement amount (0, 0) stored in the coordinate storage unit 26 is transmitted to the transmission signal generation unit 25 as an output value. Even when the current pressing state of the touch pad 5 is off, the output value determination unit 24 also includes the input coordinate storage unit when the pressing state TCpre stored in the touch pad state storage unit 27 is on. The amount of movement (0, 0) stored in 26 is transmitted to the transmission signal generator 25 as an output value.

  Therefore, while the touch pad 5 is pressed, even if the finger moves on the touch pad 5, the movement amount (0, 0) is transmitted to the PC body 4 as an output value. Therefore, the cursor displayed on the display unit 3a does not move. As a result, the PC main body 4 can sufficiently recognize a click operation (including a double click operation). That is, the user can perform a click operation without being aware of the movement of the finger while pressing the touch pad.

[Flow of click operations]
Next, the touch pad pressing state in the processing flow in the remote controller 2 will be described. FIG. 6 is a flowchart showing the flow of a click operation by pressing the touch pad.

  First, when there is some change in the touch pad 5, the touch pad 5 detects that a finger touches the touch pad 5 (S21). That is, the pointing process is started (S22).

  The input coordinate detection unit 21 detects whether or not there is a coordinate input in a state where the touch pad 5 is not pressed (S23). When the input coordinate detection unit 21 detects a coordinate input (YES in S23), the remote controller 2 performs the process of S7 shown in FIG. That is, the remote controller 2 transmits an output value indicating the movement amount (Xin−Xpre, Yin−Ypre) to the PC main body 4. If the input coordinate detection unit 21 does not detect a coordinate input (NO in S23), the process proceeds to S24.

  Next, when the touch pad 5 is pressed (S24), the remote controller 2 performs the process of S10 shown in FIG. That is, the remote controller 2 transmits an output value indicating the movement amount (0, 0) to the PC main body 4. Then, this process is repeated while the touch pad is pressed (S25).

  When the pressing of the touch pad 5 is completed (S26), the remote controller 2 performs the process shown in S11 shown in FIG. That is, even when the pressing of the touch pad 5 is completed, the remote controller 2 transmits an output value indicating the movement amount (0, 0) to the PC body 4.

  That is, the output value indicating the movement amount (0, 0) is continuously transmitted to the PC body 4 from when the touch pad 5 is pressed until the pressing is completed. For this reason, the PC main body 4 does not move the cursor while the touch pad 5 is being pressed, so that it is possible to reliably recognize the click operation by the user. That is, the user can perform a click operation without being aware of the movement of the finger while pressing the touch pad.

  Next, a case where a double click operation is performed will be described. FIG. 7 is a flowchart showing a flow of a click operation (ie, a double click operation) when the touch pad is pressed twice.

  The processes in S31 to S36 shown in FIG. 7 are the same as the processes in S21 to S26 shown in FIG.

  When the pressing of the touch pad 5 is completed in S36, if the input coordinates (Xin, Yin) and (Xpre, Ypre) indicate different coordinates, the input coordinate detection unit 21 has a coordinate input as in S33. Is detected (S37). When the input coordinate detection unit 21 detects a coordinate input (YES in S37), the remote controller 2 performs the process of S7 shown in FIG. That is, the remote controller 2 transmits an output value indicating the movement amount (Xin−Xpre, Yin−Ypre) to the PC main body 4. If the input coordinate detection unit 21 does not detect a coordinate input (NO in S37), the process proceeds to S38.

  On the other hand, when the input coordinates (Xin, Yin) and (Xpre, Ypre) indicate the same coordinates, the input coordinate detection unit 21 determines that there is no coordinate input, and ends the pointing operation process ( S38).

  If there is any change in the touch pad 5 again, the touch pad 5 detects that a finger touches the touch pad 5 (S39). That is, the pointing process is started (S40). Thereafter, in S41, the same processing as S33 is performed, and when the touch pad 5 is pressed again, the processing of S10 shown in FIG. 5 is performed as in S34 (S42).

  Here, the control unit 41 of the PC main body 4 is, for example, the time from the first pressing to the second pressing (for example, from the pressing of the touch pad 5 in S34 until the touch pad 5 is pressed again in S42. Time) and the movement amount of the cursor in the meantime are compared with the aforementioned movement amount allowable value and click time interval allowable value stored in the storage unit 42. When both the time and the movement amount are equal to or less than the allowable value, it is recognized as a double click operation. Thereafter, the processing in S43 and S44 is the same as the processing in S35 and S36. Then, the remote control 2 ends the pointing operation process (S45).

  Therefore, the first click of the double click operation is performed in the processes in S34 to S36, and the second click of the double click operation is performed in the processes in S42 to S44. In each of the first and second click operations, the output value indicating the movement amount (0, 0) is continuously transmitted to the PC body 4 from when the touch pad 5 is pressed until the pressing is completed. For this reason, the PC main body 4 does not move the cursor while the touch pad 5 is being pressed, so that the click operation by the user can be reliably recognized. That is, the user can easily perform a double-click operation.

[Relationship between touchpad pressing state and cursor movement]
Here, the relationship between the state of the touch pad when the click operation is performed and the operation of the cursor displayed on the display unit 3a of the display device 3 will be described with reference to FIG.

  First, when the user's finger touches the touch pad 5 and presses the touch pad 5, the push SW 7 is pressed in conjunction. Thereby, a click operation is started. When a click operation is performed using the touch pad 5, there is a possibility that the shaking of the finger increases while the touch pad 5 is being pressed. That is, the movement amount data detected on the touch pad 5 increases in both the x and y directions.

  However, in the remote controller 2 according to the present embodiment, the output value determination unit 24 determines which of the movement amount (Xin-Xpre, Yin-Ypre) and the movement amount (0, 0) is the output value. . The output value determination unit 24 determines the movement amount (0, 0) stored in the input coordinate storage unit 26 as an output value while the touch pad 5 is pressed, and transmits the output value to the transmission signal generation unit 25.

  Therefore, the PC main body 4 can sufficiently recognize the user's click operation by receiving the data that does not move the cursor (the output value indicating the movement amount (0, 0)).

  On the other hand, until the click operation is once completed and the click operation (double click operation) is started again (from the click completion to the start of double click), the amount of finger movement is the PC body in both the x and y directions. 4 is small enough to be recognized as a double-click operation. In addition, regarding the time interval between the click operation (first click operation) and the double click operation (second click operation), the PC body 4 determines that the second click operation is the start of the double click operation. Small.

  At this time, since the touch pad 5 is not pressed, the output value determination unit 24 determines the movement amount (Xin−Xpre, Yin−Ypre) calculated by the output value determination unit 24 as an output value. It transmits to the transmission signal generation part 25. Therefore, the PC main body 4 moves the cursor by a movement amount corresponding to the movement amount of the finger on the touch pad 5 from the completion of the click to the start of the double click.

  Note that the relationship between the pressed state of the touch pad and the operation of the cursor from the start of the double click to the completion of the double click is the same as the above relationship from the start of the click to the completion of the click, and the description thereof is omitted. Even in the second click operation, the PC body 4 does not move the cursor while the touch pad 5 is being pressed, so that the user can reliably recognize the click operation. That is, the user can easily perform a double-click operation.

[Modification]
Although the touchpad that can be pressed has been described in the present embodiment, the present invention is not limited to this. That is, for example, any pointing device that can perform a click operation, such as a tablet, a mouse, a trackball, or a stick-type pointing device, is applicable.

  Here, in the remote controller 2 according to the present embodiment, the input coordinate detection unit 21 detects the detection result on the touch pad as absolute coordinates. That is, the detection result on the touch pad 5 is detected as absolute coordinates. This is not limited to the touch pad 5, and for example, the detection result in the tablet is also detected as absolute coordinates.

  On the other hand, in the case of a trackball, a stick-type pointing device, or the like, the input coordinate detection unit 21 detects the detection results of these devices as relative coordinates. Here, the pointing process when the input coordinate detection unit 21 detects relative coordinates will be described.

  FIG. 9 is a flowchart showing the flow of the pointing process when the pointing device is used. The pointing device from which the relative coordinates are detected is hereinafter referred to as a coordinate input unit (coordinate input means). The touch pad state storage unit 27 stores a pressed state of the coordinate input unit, that is, a pressed state (SCpre) of the push SW (press input means), instead of the pressed state (TCpre) of the touch pad.

  First, when there is some change in the coordinate input unit, the pointing process is started. The input key state determination unit 23 determines that the pressed state SCpre is off when the push SW is previously pressed (SCpre) in the coordinate input unit, that is, when the push SW has not been pressed before this detection. S51).

  Next, the transmission signal generation unit 25 inquires of the input coordinate detection unit 21 about the current input coordinates (S52). In response to this inquiry, the input coordinate detection unit 21 detects the detection result in the coordinate input unit, and calculates the input coordinate from the detection result. Since the input coordinates (Xin, Yin) detected at this time are relative coordinates (Xin, Yin), Xin represents the x-direction movement amount, and Yin represents the y-direction movement amount.

  Thereafter, the input key state determination unit 23 inquires of the input key detection unit 22 about the pressing information A (S53). The pressing information A is information indicating whether or not the function key 6 and the push SW of the coordinate input unit are pressed. When receiving an inquiry about the pressing information A, the input key detecting unit 22 detects information (pressing information A) indicating whether or not the function key 6 and the push SW are pressed. Then, the input key detection unit 22 transmits this press information A to the input key state determination unit 23.

  As in S5 of FIG. 5, the input key state determination unit 23 determines whether or not the pressing information A indicates no input, that is, whether or not the pressing information A indicates that the function key 6 or the push SW is pressed. Determination is made (S54).

  When the pressing information A means no input (does not indicate pressing of the function key 6 or the push SW) (YES in S54), the current pressing state of the push SW is not pressed (off). Show. At this time, the input key state determination unit 23 determines whether or not the previous pressing state (SCpre) of the push SW has been pressed (S55).

  Here, as in the case of the touch pad 5, the touch pad state storage unit 27 indicates that the previous pressing state (SCpre) of the coordinate input unit has been pressed, and the pressing state “SCpre = ON”. Is stored, and when not pressed, the pressed state “SCpre = off” is stored. The input key state determination unit 23 reads the SC on signal from the touch pad state storage unit 27 when the key is pressed and the SC off signal when the key is not pressed. Thereby, the input key state determination unit 23 determines the pressed state SCpre.

  When SCpre = off (NO in S55), the input key state determination unit 23 indicates that the current push state and the push state SCpre of the push SW are not pressed. Is transmitted to the output value determination unit 24. At this time, the input key state determination unit 23 transmits the function key 6 and push SW pressing information A (current pressing state) to the transmission signal generation unit 25.

  Upon receiving this determination signal (SC off signal), the output value determination unit 24 detects the relative coordinates (Xin, Yin) as the movement amount (Xin, Yin) and determines the movement amount (Xin, Yin) as the output value. To do. Then, this output value is transmitted to the transmission signal generator 25.

  The transmission signal generation unit 25 transmits the pressing information A received from the input key state determination unit 23 and the output value received from the output value determination unit 24 to the RF transmission / reception unit 8 as a transmission signal.

  Here, focusing on the pressing state of the push SW of the coordinate input unit, the pressing state of the push SW uses a left click signal that is a signal indicating the pressing state of the left click key, as in the case where the touch pad 5 is pressed. Sent. The determination signal received by the output value determination unit 24 from the input key state determination unit 23 is an SC off signal. Therefore, the transmission signal generation unit 25 transmits the left click signal (off signal) and the output value indicating the movement amount (Xin, Yin) to the RF transmission / reception unit 8 as a transmission signal. Then, the RF transceiver 8 converts this transmission signal into an RF signal and transmits it to the PC body 4 (S56).

  Thereafter, the input coordinate detection unit 21 determines whether or not the relative coordinates (Xin, Yin) = (0, 0) (S57). If YES in S57, the pointing process is terminated. If NO, the process returns to S52.

  Further, when the pressing information A does not mean no input (indicating that the function key 6 or the push SW is pressed) (NO in S54), the input key state determination unit 23 determines that the pressing information A is the coordinate input unit. It is determined whether or not a push, that is, push push is indicated (S58).

  When the pressing information A indicates that the push SW is pressed (YES in S58), when the input key state determination unit 23 determines that the current pressing state of the push SW is on, it outputs an SC on signal as a determination signal. It transmits to the value determination part 24.

  When receiving the determination signal (SC on signal), the output value determining unit 24 determines the movement amount (0, 0) stored in the input coordinate storage unit 26 as an output value. Then, this output value is transmitted to the transmission signal generator 25. At this time, the input key state determination unit 23 rewrites the pressed state SCpre stored in the touchpad state storage unit 27 to ON. Then, the transmission signal generation unit 25 transmits the pressing information A received from the input key state determination unit 23 and the output value received from the output value determination unit 24 to the RF transmission / reception unit 8 as a transmission signal.

  Here, paying attention to the pressed state of the push SW, since the determination signal received by the output value determination unit 24 from the input key state determination unit 23 is an SC on signal, the transmission signal generation unit 25 generates a left click signal (on signal). ) And an output value indicating the amount of movement (0, 0) are transmitted to the RF transceiver 8 as transmission signals. Then, the RF transceiver 8 converts this transmission signal into an RF signal and transmits it to the PC main body 4 (S59). Thereafter, the process returns to S52.

  If SCpre = on (YES in S55), the current push state of the push SW is off, but the previous push state SCpre of the push SW indicates that it is on. The SC on signal is transmitted to the output value determination unit 24 as a determination signal. At this time, the input key state determination unit 23 transmits the function key 6 and push SW pressing information A (current pressing state) to the transmission signal generation unit 25.

  When receiving the determination signal (SC on signal), the output value determining unit 24 determines the movement amount (0, 0) stored in the input coordinate storage unit 26 as an output value. Then, this output value is transmitted to the transmission signal generator 25. At this time, the input key state determination unit 23 rewrites the pressed state SCpre stored in the touchpad state storage unit 27 to off.

  The transmission signal generation unit 25 transmits the pressing information A received from the input key state determination unit 23 and the output value received from the output value determination unit 24 to the RF transmission / reception unit 8 as a transmission signal. At this time, the transmission signal generation unit 25 transmits the left click signal (off signal) and the output value indicating the movement amount (0, 0) to the RF transmission / reception unit 8 as a transmission signal. Then, the RF transceiver 8 converts this transmission signal into an RF signal and transmits it to the PC main body 4 (S60). Thereafter, the process returns to S57.

  When the pressing information A does not indicate that the push SW is pressed (NO in S58), the input key state determination unit 23 determines that the push SW pressing state SCpre is off (S62). Subsequent processes S62 to S64 are the same processes as S13 to S15 shown in FIG.

  As described above, regardless of whether the pointing device is a touch device that detects absolute coordinates, such as the touch pad 5, or is a pointing device that detects relative coordinates, such as a trackball, the output value determining unit 24 The movement amount (0, 0) stored in the coordinate storage unit 26 is determined as an output value and transmitted to the transmission signal generation unit 25. Then, the transmission signal generation unit 25 transmits a transmission signal including the pressing information A and the output value to the PC main body 4 via the RF transmission / reception unit 8.

  That is, regardless of the pointing device, while the user is performing a click operation, the PC main body 4 is moved by a movement amount (0, 0) so that the PC main body 4 does not move the cursor displayed on the display unit 3a. ). As a result, the PC body 4 can sufficiently recognize the user's click operation. That is, when the user presses a pointing device such as a touch pad, a click operation can be performed without being aware of finger movement.

  In the remote controller 2 according to the present embodiment, the left click signal is used for the pressed state of the touch pad 5, but the present invention is not limited to this, and a unique signal different from the left click signal may be used. . This is effective, for example, when the remote control 2 does not have a left click key.

  In this case, the PC main body 4 can operate various applications using the unique signal depending on the setting of the PC main body 4 by providing a dedicated driver capable of receiving the unique signal.

[Embodiment 2]
Another embodiment of the present invention will be described with reference to FIGS. 10 to 11 as follows. In addition, about the member which has the same function as Embodiment 1, the same code | symbol is attached and the description is abbreviate | omitted.

  In the remote controller 2 according to the first embodiment, when the touch pad 5 is pressed, the output value determination unit 24 determines the movement amount (0, 0) stored in the input coordinate storage unit 26 as an output value. Then, the transmission signal generation unit 25 transmits the output value and the pressing information A as a transmission signal to the PC main body 4 via the RF transmission / reception unit 8. Thereafter, the input coordinate detection unit 21 performs the process of S2 shown in FIG. That is, in the first embodiment, the process immediately proceeds from S10 to S2 shown in FIG.

  On the other hand, in the remote control (coordinate input device) according to the second embodiment, a standby time is provided during processing while the touch pad 5 is pressed. That is, in this remote control, the processing is temporarily stopped between the processing of S10 to S2 shown in FIG.

[Remote control configuration]
A schematic configuration of the remote control according to the second embodiment will be described. The remote control according to the second embodiment includes a timer (not shown). When the transmission signal is transmitted from the transmission signal generation unit 25 to the PC main body 4 via the RF transmission / reception unit 8, the timer starts measuring time and transmits a timing start signal to the output value determination unit 24. In addition, a standby time is set in advance for this timer, and after waiting for this standby time from the start of timing, the timer transmits a timing end signal for notifying the end of timing to the output value determining unit 24.

  When the output value determination unit 24 receives the time measurement start signal from the timer, the output value determination unit 24 transmits a function stop signal to the input coordinate detection unit 21. When receiving the function stop signal, the input coordinate detection unit 21 stops the detection of the detection result on the touch pad 5 and the operation of assigning the input coordinates (Xin, Yin) to the input coordinates (Xpre, Ypre). Further, the output value determination unit 24 determines the movement amount (0, 0) from the input coordinate storage unit 26 as an output value, and stops transmitting to the transmission signal generation unit 25.

  On the other hand, when the output value determination unit 24 receives the time measurement end signal from the timer, the output value determination unit 24 transmits a function stop release signal to the input coordinate detection unit 21. When the input coordinate detection unit 21 receives the function stop release signal, the input coordinate detection unit 21 restarts the detection of the detection result on the touch pad 5 and the above substitution operation. The output value determination unit 24 starts determining and transmitting an output value indicating the movement amount (0, 0).

[Pointing operation processing on the remote control]
Next, the flow of processing in the remote controller according to the second embodiment will be described. FIG. 10 is a flowchart illustrating the flow of the pointing operation process in the remote controller according to the second embodiment. Note that the processing of S71 to S78 shown in FIG. 10 is the same as the processing of S1 to S8 shown in FIG.

  When the pressing information A does not mean no input (indicating that the function key 6 or the push SW 7 is pressed) (NO in S75), the input key state determination unit 23 indicates that the pressing information A indicates that the touch pad 5 is pressed. It is determined whether or not it is shown (S79).

  When the pressing information A indicates that the touch pad 5 is pressed (YES in S79), if the input key state determination unit 23 determines that the current pressing state of the touch pad 5 is on, a TC on signal is used as a determination signal. Is transmitted to the output value determination unit 24. Note that the process of S80 is the same as S10 shown in FIG.

  In S80, when a transmission signal is transmitted from the transmission signal generation unit 25 to the PC main body 4 via the RF transmission / reception unit 8, the timer starts measuring time. At this time, a timing start signal is transmitted to the output value determination unit 24. When a time corresponding to a standby time preset in the timer (here, 1 second) elapses, the timer ends timing and transmits a timing end signal to the output value determination unit 24. That is, after 1 second has elapsed since the transmission signal is transmitted from the transmission signal generation unit 25 to the PC main body 4 via the RF transmission / reception unit 8, the process returns to S72, and the remote control enters the standby state for 1 second. (S81). In the present embodiment, the standby time set in advance for the timer is 1 second, but is not limited to this.

  That is, the output value determination unit 24 transmits a function stop signal to the input coordinate detection unit 21 when receiving the timing start signal. Thereby, the input coordinate detection unit 21 stops the detection of the detection result on the touch pad 5 and the operation of substituting the input coordinates (Xin, Yin) into the input coordinates (Xpre, Ypre). That is, while the timer is counting, the process does not shift to S72. The output value determining unit 24 stops determining and transmitting the output value indicating the movement amount (0, 0) while the timer is counting.

  And the output value determination part 24 will transmit a function stop cancellation | release signal to the input coordinate detection part 21, if a clocking end signal is received from a timer after 1 second. Thereby, the input coordinate detection unit 21 resumes the detection of the detection result on the touch pad 5 and the above substitution operation. That is, at this point, the process proceeds to S72. The output value determination unit 24 starts determining and transmitting an output value indicating the movement amount (0, 0).

  The transmission signal generation unit 25 does not generate a transmission signal because no output is transmitted from the output value determination unit 24 while the timer is counting. Therefore, during this time, the transmission signal is not transmitted to the PC main body 4 via the RF transmission / reception unit 8.

  Thereby, while the timer is counting, the remote control according to the second embodiment determines and transmits the output value indicating the movement amount (0, 0) in the output value determination unit 24, and touches the input coordinate detection unit 21. The detection of the detection result at the pad 5 and the substitution operation at the input coordinate detection unit 21 are stopped. Further, during this time, in the remote control according to the second embodiment, the process of transmitting the transmission signal of the transmission signal generation unit 25 and the RF signal of the RF transmission / reception unit 8 is stopped.

  Accordingly, since each process is stopped while the timer is counting, the power supply to the input coordinate detection unit 21, the output value determination unit 24, the transmission signal generation unit 25, and the RF transmission / reception unit 8 is turned off. be able to. That is, the power consumption of the entire remote control can be suppressed.

  When the input key detecting unit 22 detects a notification that there is some input change in the standby state for 1 second in S81 (when new pressing information A is detected), the standby state for 1 second is canceled. Then, the process proceeds to S72. Also, the standby time is set to 1 second because the input key detection unit 22 cannot detect new press information A and the input key detection unit 22 is 1 second even when the standby state is not released. This is to make it possible to detect the pressed information A within a new time. Thereby, the detection mistake of the pressing information A by the input key detection part 22 in the standby state in S81 can be suppressed.

  Also, the standby time is provided in S81 so that when the function key 6 or the touch pad 5 is completely pressed, the PC body 4 reliably recognizes that the press has been completed. That is, to prevent the PC body 4 from continuously recognizing that the touch pad 5 is in the pressed state even though the function key 6 or the touch pad 5 has been pressed.

  Furthermore, even when the standby time is not set, that is, when the standby state is maintained, when the input key detection unit 22 detects a notification that there is some input change (new pressing information A is detected) In the case), the standby state is canceled. If the input key detection unit 22 cannot detect new pressing information A and the standby state is not released, when the user presses the touch pad 5 or the function key 6 again, the process proceeds to S72.

  As a result, when the standby time is not set, the above-described processes are stopped while the touch pad 5 is being pressed, so that the power consumption of the entire remote control can be further suppressed.

  In addition, since the process of S83-S86 which transfers to the case of NO by S79 is the same process as S12-S15 shown in FIG. 5, the description is abbreviate | omitted.

  Although the pointing device that detects absolute coordinates has been described here, the present invention is not limited to this, and the present invention can also be applied to a pointing device that detects relative coordinates.

[Relationship between touchpad pressing state and cursor movement]
Here, the relationship between the state of the touch pad when the click operation is performed and the operation of the cursor displayed on the display unit 3a of the display device 3 will be described with reference to FIG.

  First, when the user's finger touches the touch pad 5 and presses the touch pad 5, the push SW 7 is pressed in conjunction. Thereby, a click operation is started. When a click operation is performed using the touch pad 5, there is a possibility that the shaking of the finger increases while the touch pad 5 is being pressed. That is, the movement amount data detected on the touch pad 5 increases in both the x and y directions.

  However, in the remote control according to the present embodiment, the output value determination unit 24 determines which of the movement amount (Xin-Xpre, Yin-Ypre) and the movement amount (0, 0) is the output value every second. is doing. The output value determination unit 24 determines the movement amount (0, 0) stored in the input coordinate storage unit 26 as an output value every second while the touch pad 5 is pressed, and a transmission signal generation unit 25. That is, in S81 shown in FIG. 10, while the remote control is in the standby state for 1 second, the output value indicating the movement amount (0, 0) is not transmitted.

  Accordingly, since each process is stopped while the timer is counting, the power supply to the input coordinate detection unit 21, the output value determination unit 24, the transmission signal generation unit 25, and the RF transmission / reception unit 8 is turned off. be able to. That is, the power consumption of the entire remote control can be suppressed.

  Even if each process is stopped while the timer is counting, the PC body 4 receives data that does not move the cursor (an output value indicating the movement amount (0, 0)). This makes it possible to fully recognize the user's click operation.

  On the other hand, until the click operation is once completed and the click operation (double click operation) is started again (from the click completion to the start of double click), the amount of finger movement is the PC body in both the x and y directions. 4 is small enough to be recognized as a double-click operation. The time interval between the click operation (first click operation) and the double click operation (second click operation) is such that the PC body 4 can determine that the second click operation is the start of the double click operation. small.

  At this time, since the touch pad 5 is not pressed, the output value determination unit 24 determines the movement amount (Xin−Xpre, Yin−Ypre) calculated by the output value determination unit 24 as an output value. It transmits to the transmission signal generation part 25. Therefore, the PC main body 4 moves the cursor by a movement amount corresponding to the movement amount of the finger on the touch pad 5 from the completion of the click to the start of the double click.

  Note that the relationship between the pressed state of the touch pad and the operation of the cursor from the start of the double click to the completion of the double click is the same as the above relationship from the start of the click to the completion of the click, and the description thereof is omitted.

  Even in the second click operation, since each process is stopped while the timer is counting, the input coordinate detection unit 21, the output value determination unit 24, the transmission signal generation unit 25, and the RF transmission / reception unit 8 are stopped. The power supply can be turned off. That is, the power consumption of the entire remote control can be suppressed. Since the PC main body 4 does not move the cursor while the touch pad 5 is pressed, the click operation by the user can be reliably recognized. That is, the user can easily perform a double-click operation.

  Here, in the first and second embodiments, the case where the touchpad that can be pressed is mounted on the remote control has been described. However, the present invention is not limited to this. That is, for example, a pointing device such as a touch pad that can be clicked may be mounted on a notebook PC or the like. When the pointing device is mounted on a notebook PC or the like, the input key state determination unit 23, the output value determination unit 24, and the transmission signal generation unit 25 are physically separated from the control unit of the notebook PC. It does not have to be. That is, the configuration may be such that the input coordinate data detected by the control unit of the notebook PC is determined.
