  In a personal computer, a mouse is frequently used as a device for inputting a cursor position on a screen of a display device. When the mouse is used on a desk, a flat area for physically moving the mouse, in other words, a mouse operable range is necessary. The mouse operable range often changes due to various causes such as a user spreading a document or the like on a desk.

  Even if the mouse operable range is changed, the relationship between the amount of mouse movement on the desk and the amount of cursor movement on the screen can be changed according to the degree of change of the mouse operable range. Absent. For this reason, an operation of lifting the mouse may occur in order to move the cursor on the screen to a target position. Such an operation is complicated for the user of the personal computer.

  Here, the relationship between the movement amount of the mouse and the movement amount of the cursor is referred to as “mouse movement ratio”. The mouse movement ratio itself can be set indirectly, for example, by the user manually setting the moving speed of the cursor via an operating system (OS) or a mouse driver.

  However, in this case, since the moving speed of the cursor is not changed according to the degree of change of the mouse operable range, the mouse movement ratio cannot be changed according to the degree of change of the mouse operable range. When the user wants to change the mouse movement ratio according to the degree of change of the mouse operable range, the user empirically predicts the appropriate cursor movement speed according to the degree of change of the mouse operable range. Need to be set. Such an operation is complicated for the user of the personal computer. Further, the moving speed of the cursor cannot be set independently for the horizontal direction and the vertical direction. Therefore, it is virtually impossible to follow the change of the mouse operable range.

  An object of the present invention is to provide an information processing apparatus capable of setting an input device movement ratio in accordance with a change in an input device operable range.

  The disclosed information processing apparatus includes an input device position calculation unit and an input device movement ratio setting unit. The input device position calculation unit calculates the position of the input device at the plurality of vertices based on the result of measuring the position of the input device at the plurality of vertices of the input device operable range that is the range in which the input device can operate. The input device movement ratio setting unit calculates the horizontal distance and the vertical distance of the input device operable range based on the calculation result in the input device position calculating unit, and the horizontal distance of the input device operable range. And on the screen of the display device according to the amount of movement of the input device and the movement of the input device, based on the distance in the vertical direction, the horizontal resolution and the vertical resolution of the screen of the display device, and the resolution of the input device. The input device movement ratio that determines the relationship with the amount of movement of the cursor that moves is calculated and set in the horizontal and vertical directions of the screen of the display device.

  According to the disclosed information processing device, the input device movement ratio can be changed in accordance with a change in the operable range of the input device connected to the information processing device.

  FIG. 1 is a diagram illustrating an example of an information processing apparatus. FIG. 2 is a diagram illustrating an example of a schematic appearance of the information processing apparatus.

  The information processing apparatus includes a personal computer (PC) 1, a mouse 2, and a display device 3. The personal computer 1 includes a receiving unit 11, a ratio processing unit 12, a mouse control unit 16, and a display control unit 17. The ratio processing unit 12 includes a mouse movement ratio setting unit 13, a mouse position calculation unit 14, and a mouse position measurement unit 15. The mouse movement ratio setting unit 13 includes a screen storage unit 131 and a ratio table storage unit 132. The mouse control unit 16 includes a mouse resolution storage unit 161 and a movement ratio storage unit 162. The display control unit 17 includes a screen resolution storage unit 171. The mouse 2 includes a transmission unit 21 and a position information notification trigger unit 22.

  As shown in FIG. 2, the personal computer 1 is provided in, for example, one housing 10. A mouse 2 and a display device 3 are provided outside the housing 10 independently of the housing 10 of the personal computer 1. For example, the personal computer 1 and the mouse 2 are wirelessly connected. The personal computer 1 and the mouse 2 may be connected by a connector. The personal computer 1 and the display device 3 are connected by, for example, a connector. The personal computer 1 and the display device 3 may be wirelessly connected.

  The mouse 2 is an input device and is a pointing device that inputs the position of the cursor on the screen of the display device 3. The personal computer 1 includes an input device such as a keyboard in addition to the mouse 2.

  As shown in FIG. 2, the mouse 2 can operate without any trouble within the mouse operable range R. The mouse operable range R is a range in which the mouse 2 can operate. The mouse operable range R is, for example, a flat area on the desk D, and can be defined by a plurality of vertices, for example, four vertices. The four vertices are an upper left vertex (L, U), an upper right vertex (R, U), a lower right vertex (R, L), and a lower left vertex (L, L). The horizontal distance of the mouse operable range R is “X”, and the vertical distance of the mouse operable range R is “Y”.

  As will be described later, the mouse 2 inputs the position of the mouse 2 at the four vertices of the mouse operable range R to the ratio processing unit 12 at a predetermined timing.

  The display device 3 is a liquid crystal display device, for example, and displays various characters, figures, and the like on the screen. The display device 3 displays a cursor that moves on the screen of the display device 3 in response to the movement of the mouse 2, in other words, a mouse cursor. On the screen of the display device 3, as shown in FIG. 2, the horizontal resolution A and the vertical resolution B are unique values for each display device 3 and are determined in advance. The horizontal resolution A and the vertical resolution B are not fixed and may be changed.

  The mouse operable range R changes depending on the convenience of work on the user's desk D. Accordingly, the horizontal distance X and the vertical distance Y of the mouse operable range R change. The distance X is the maximum movement amount in the horizontal direction of the mouse 2 at that time, and the distance Y is the maximum movement amount Y in the vertical direction of the mouse 2 at that time. On the other hand, the horizontal resolution A and the vertical resolution B of the screen of the display device 3 are unique values and do not change. Therefore, as will be described later, in the ratio processing unit 12, the horizontal mouse movement ratio α ′ that defines the relationship between the distance X and the resolution A, and the vertical mouse movement ratio β that defines the relationship between the distance Y and the resolution B. 'And are changed independently. By defining the relationship between the distance and the resolution, the relationship between the movement amount of the mouse 2 and the movement amount of the cursor is determined. The mouse movement ratio α ′ in the horizontal direction and the mouse movement ratio β ′ in the vertical direction are collectively referred to as the movement ratio of the mouse 2.

  The ratio processing unit 12 is called from, for example, an OS (operating system) of the personal computer 1. The OS is a control unit that controls the entire personal computer 1 and is activated when the personal computer 1 is turned on. When the OS is activated when the power is turned on, the OS calls the ratio processing unit 12 to execute the movement ratio setting process of the mouse 2.

  Note that after the OS is activated, the ratio processing unit 12 may be called from, for example, the control panel of the personal computer 1 to change the movement ratio of the mouse 2. In addition, after the OS is activated, the ratio processing unit 12 may be called by a predetermined key input from a keyboard or the like to change the movement ratio of the mouse 2.

  When called from the OS, the ratio processing unit 12 causes the mouse movement ratio setting unit 13 to calculate the mouse movement ratio. Specifically, the mouse movement ratio setting unit 13 acquires the horizontal distance X and the vertical distance Y of the mouse operable range R, and the horizontal resolution A and the vertical resolution of the screen of the display device 3. B is acquired, and the resolution Z of the mouse 2 is acquired. Then, the mouse movement ratio setting unit 13 calculates the mouse movement ratio based on the acquired distance X and distance Y, the acquired resolution A and resolution B, and the acquired resolution Z.

  As described above, the mouse movement ratio is a value that defines the relationship between the movement amount of the mouse 2 and the movement amount of the cursor that moves on the screen of the display device 3 in accordance with the movement of the mouse 2. As described above, the mouse movement ratio is actually calculated for each of the horizontal direction and the vertical direction of the screen of the display device 3. The mouse movement ratio setting unit 13 stores the calculated mouse movement ratio in the mouse resolution storage unit 161 as described later. As a result, the mouse movement ratio is set in the mouse control unit 16.

  For example, the mouse movement ratio setting unit 13 acquires the resolution Z of the mouse 2 as follows.

  The acquisition of the distance X and the distance Y, the acquisition of the resolution A and the resolution B, and the acquisition of the resolution Z may be performed first. Here, for convenience of explanation, description will be made in the order of acquisition of resolution Z, acquisition of resolution A and resolution B, and acquisition of distance X and distance Y.

  The resolution Z of the mouse 2 is held by, for example, the mouse resolution storage unit 161 by the mouse control unit 16. The mouse control unit 16 is, for example, a part that controls the mouse of the OS, in other words, a mouse driver and controls the mouse 2. The mouse resolution storage unit 161 is a storage area used by the mouse control unit 16 in a storage area used by the OS. The resolution Z of the mouse 2 is determined according to the mouse 2 and is not changed, and is represented by cpi (character per inch), for example.

  For example, the mouse movement ratio setting unit 13 sends an acquisition request for the resolution Z of the mouse 2 to the mouse control unit 16. When the mouse control unit 16 receives an acquisition request for the resolution Z of the mouse 2, the mouse control unit 16 reads the resolution Z of the mouse 2 from the mouse resolution storage unit 161 and sends the read resolution Z of the mouse 2 to the mouse movement ratio setting unit 13. Thereby, the mouse movement ratio setting unit 13 acquires the resolution Z of the mouse 2 from the mouse control unit 16 and holds it.

  Next, the mouse movement ratio setting unit 13 acquires the horizontal resolution A and the vertical resolution B of the screen of the display device 3 as follows, for example.

  The screen resolution of the display device 3 is held in the screen resolution storage unit 171 by the display control unit 17, for example. The display control unit 17 is a part that controls display on the display device 3 of the OS, for example, and controls the display device 3. The screen resolution storage unit 171 is a storage area used by the display control unit 17 in a storage area used by the OS. The resolution of the screen is determined according to the display device 3 and is not changed, and is represented by, for example, dpi (dot per inch). As described above, the screen resolution of the display device 3 actually includes the horizontal resolution A of the screen and the vertical resolution B of the screen.

  For example, the mouse movement ratio setting unit 13 sends a screen resolution acquisition request to the display control unit 17. Upon receiving the screen resolution acquisition request, the display control unit 17 reads the screen resolutions A and B from the screen resolution storage unit 171, and sends the read screen resolutions A and B to the mouse movement ratio setting unit 13. Accordingly, the mouse movement ratio setting unit 13 acquires the screen resolution of the display device 3 from the display control unit 17 and holds it.

  Next, the mouse movement ratio setting unit 13 acquires the horizontal distance X and the vertical distance Y of the mouse operable range R as follows, for example.

  For each of the four vertices of the mouse operable range R, the mouse movement ratio setting unit 13 displays four input confirmation screens instructing the input of the position of the mouse 2 at each vertex. The four input confirmation screens are displayed in a predetermined order. For example, as four input confirmation screens, an upper left vertex input confirmation screen, an upper right vertex input confirmation screen, a lower right vertex input confirmation screen, and a lower left vertex input confirmation screen are displayed in this order. Note that the display order of the four input confirmation screens is not limited to this order, and may be another order.

  The upper left vertex input confirmation screen is a screen for instructing input of the upper left vertex (L, U) shown in FIG. The upper right vertex input confirmation screen is a screen for instructing input of the upper right vertex (R, U) shown in FIG. The lower right vertex input confirmation screen is a screen for instructing input of the lower right vertex (R, L) shown in FIG. The lower left vertex input confirmation screen is a screen for instructing input of the lower left vertex (L, L) shown in FIG.

  When the mouse movement ratio setting unit 13 is determined in advance, for example, when the ratio processing unit 12 is called from the OS, four input confirmation screens are displayed accordingly. Specifically, the mouse movement ratio setting unit 13 is called from the ratio processing unit 12 called from the OS, and reads each of the four input confirmation screens from the screen storage unit 131 in a predetermined order as described above. The display control unit 17 is requested to display each of the read screens. When requested to display a screen from the mouse movement ratio setting unit 13, the display control unit 17 displays the requested screen on the display device 3.

  Note that the mouse movement ratio setting unit 13 actually sets screens other than the four input confirmation screens in a predetermined order from the screen storage unit 131 in a predetermined order, as will be described later with reference to FIG. The data is read out and displayed on the display device 3 by the display control unit 17.

  When there is a predetermined input during the display of each of the four input confirmation screens, the mouse movement ratio setting unit 13 determines the position of the mouse 2 at that time according to the predetermined input. taking measurement. Then, the mouse position calculation unit 14 calculates the position of the mouse 2 at the four vertices based on the result of measuring the position of the mouse 2 at the four vertices of the mouse operable range R.

  The predetermined input is, for example, “triple click” of the mouse 2. The predetermined input may be other than a triple click, and may be a special operation of the mouse 2. In FIG. 1, the triple click of the mouse 2 is illustrated as “switch input”.

  For example, when the mouse 2 is triple clicked during the period when the upper left vertex input confirmation screen is displayed on the display device 3, the mouse movement ratio setting unit 13 measures the position of the mouse 2 at that time. The position of the mouse 2 acquired at this time is the position of the top left vertex (L, U). In addition, when the mouse 2 is triple clicked during the display period of the upper left vertex input confirmation screen, the mouse movement ratio setting unit 13 displays the next screen, in other words, the upper right vertex input confirmation screen.

  When the mouse 2 is triple-clicked during the display period of the upper right vertex input confirmation screen, the position of the upper right vertex (R, U) is measured, and the next lower right vertex input confirmation screen is displayed. When the mouse 2 is triple-clicked during the display period of the lower right vertex input confirmation screen, the position of the lower right vertex (R, L) is measured, and the next lower left vertex input confirmation screen is displayed. When the mouse 2 is triple-clicked during the display period of the lower left vertex input confirmation screen, the position of the lower left vertex (L, L) is measured.

  FIG. 3 is an explanatory diagram of obtaining the position of the mouse.

  For example, when the left button is triple-clicked, the mouse 2 transmits a trigger signal to the receiving unit 11 by radio. The trigger signal is a signal indicating that the mouse 2 has been triple-clicked, and serves as a trigger for acquiring the position of the mouse 2.

  Specifically, the location information notification trigger unit 22 checks whether or not the left button has been triple clicked, and if the left button has been triple clicked, forms a signal indicating that the left button has been triple clicked. Then, the data is sent to the transmission unit 21. The transmission unit 21 forms a trigger signal based on the signal indicating that the received left button has been triple-clicked, and transmits the trigger signal to the reception unit 11 of the personal computer 1. The transmission unit 21 includes a transmitter, for example, and transmits various signals to the personal computer 1.

  The receiving unit 11 includes, for example, a receiver, and receives various signals transmitted from the mouse 2. The receiving unit 11 is provided, for example, on one side surface of the casing 10 of the personal computer 1 so as to easily receive a signal from the mouse 2. The receiving unit 11 sends the received signal to the mouse control unit 16. Note that the receiving unit 11 may be provided on one side surface of the housing 10 of the personal computer 1.

  When the mouse control unit 16 receives a signal from the receiving unit 11, the mouse control unit 16 determines the type of the received signal. If the received signal is a trigger signal, the mouse control unit 16 notifies the mouse movement ratio setting unit 13 that the trigger signal has been received. When receiving the notification of the trigger signal reception, the mouse movement ratio setting unit 13 acquires the position of the mouse 2 and causes the display control unit 17 to display the next input confirmation screen as described above.

  Specifically, the mouse movement ratio setting unit 13 requests the mouse position calculation unit 14 to acquire the position of the mouse 2 when receiving notification of reception of the trigger signal. When the mouse position calculation unit 14 is requested to acquire the position of the mouse 2, the mouse position calculation unit 14 transmits a command to instruct the mouse position measurement unit 15 to measure the position of the mouse 2, in other words, a sensor operation command. When receiving the sensor operation command, the mouse position measurement unit 15 measures the position of the mouse 2 at the time of reception each time the sensor operation command is received.

  For example, as the mouse position measuring unit 15, two sensors 151 and 152 are provided as shown in FIG. The sensors 151 and 152 are provided on the side surface of the housing 10 of the personal computer 1 and the side surface on which the receiving unit 11 is provided. Specifically, the sensors 151 and 152 are provided on the side surface where the receiving unit 11 is provided, at an upper portion thereof, separated by a predetermined distance. At this time, a line segment connecting the two sensors 151 and 152 is made parallel to the bottom surface of the housing 10 of the personal computer 1. Thereby, as will be described later, the position of the mouse 2 can be acquired according to the principle of binocular stereoscopic vision. The sensors 151 and 152 may be provided on the side where the receiving unit 11 is provided in a range where the position of the mouse 2 can be acquired by triangulation as described later.

  As the sensors 151 and 152, for example, a CCD camera is used. In this case, the sensors 151 and 152 acquire two images of the mouse 2 viewed from the two sensors 151 and 152 in response to a sensor operation command based on the trigger signal from the mouse 2. Therefore, the measurement in this case is a passive measurement. The sensors 151 and 152, in other words, the mouse position measuring unit 15 sends the two acquired images to the mouse position calculating unit 14.

  The mouse position calculation unit 14 acquires the position of the mouse 2 as shown in FIG. 4 using a triangulation method according to the principle of binocular stereoscopic vision or binocular parallax based on the two received images. To do.

  FIG. 4 is an explanatory diagram of obtaining the position of the mouse.

For example, in FIG. 4, the point O _R of the right is the position of the sensor 151, a point O _L of the left is the position of the sensor 152, "P" is the position of the mouse 2. Distance sensor 151 and 152, in other words, the distance between the right point _{O R} and the left of point _{O L} is predetermined, it is "2a". The focal points f of the lenses of the cameras 151 and 152 are predetermined and have the same value. Incidentally, one of the right point O _R or the left point O _L is used as the origin of coordinates.

In this case, as shown in FIG. 4, the mouse 2 position P is the 2-dimensional image in the focus f of the lens of the camera is the right sensor 151, exists at a position P _R. Further, as shown in FIG. 4, the mouse 2 position P is the 2-dimensional image in the focus f of the lens of the camera is the left sensor 152, exists at a position P _L. Therefore, as shown in FIG. 4, the mouse position calculation unit 14 calculates the point P where the mouse 2 exists from two planes, in other words, from the two-dimensional coordinates projected on the two-dimensional image at the focal point f of the lens. The three-dimensional coordinates of the mouse 2 are obtained. In other words, the mouse position calculation unit 14, the coordinates of the coordinate and the sensor 152 of the sensor 151, based on the coordinates of the coordinates and the position P _L position P _R, according to a triangular measuring method using binocular stereopsis, mouse 2 Is calculated. Thereby, the position of the mouse 2 at each of the four vertices of the mouse operable range R is obtained by calculation.

  As the sensors 151 and 152, for example, ultrasonic sensors may be used. In this case, the sensors 151 and 152 irradiate the mouse 2 with ultrasonic waves from the two sensors 151 and 152 in response to a sensor operation command based on the trigger signal from the mouse 2 and receive the reflected waves. Thereby, the time from the output of the ultrasonic wave to the reception of the reflected wave, in other words, the distance to the mouse 2 can be obtained. Therefore, the measurement in this case is an active measurement. Based on the two distances from the sensors 151 and 152 to the mouse 2, the position of the mouse 2 can be known.

  Thereafter, the mouse movement ratio setting unit 13 calculates the horizontal distance X based on the positions of the mouse 2 at both horizontal ends of the mouse operable range R, and also calculates the vertical distance Y as the mouse operable range. Calculation is based on the position of the mouse 2 at both ends of R in the vertical direction.

  Here, the mouse operable range R is easily restricted each time the user spreads a document or the like on the desk D, for example. Accordingly, the mouse operable range R may not be strictly determined. Furthermore, the mouse operable range R formed by the acquired four vertices does not have to be rectangular, and the sides need not be parallel.

  Therefore, the mouse movement ratio setting unit 13 does not verify whether the mouse operable range R is rectangular although the screen of the display device 3 is rectangular. In other words, in the mouse operable range R shown in FIG. 2, it is not verified whether the upper side and the lower side are parallel, the left side and the right side are parallel, or whether the upper side and the lower side are perpendicular to the left side and the right side.

  Specifically, the mouse movement ratio setting unit 13, for example, the distance between the upper left vertex (L, U) and the upper right vertex (R, U), or the lower left vertex (L, L) and the right The distance X in the horizontal direction is calculated by calculating the distance between the lower vertex (R, L). In addition, the mouse movement ratio setting unit 13 may be, for example, a distance between an upper right vertex (R, U) and a lower right vertex (R, L), or an upper left vertex (L, U) and a lower left vertex. The vertical distance Y is calculated by calculating the distance to (L, L). Therefore, the mouse movement ratio setting unit 13 calculates the distance X and the distance Y using the acquired position of the mouse 2 at each of the four vertices as it is. The mouse movement ratio setting unit 13 holds the calculated distance X and distance Y.

  The horizontal distance X is defined as the distance between the upper left vertex (L, U) and the upper right vertex (R, U), the lower left vertex (L, L), and the lower right vertex (R, L). ) May be calculated based on the average of the distance between the two, or the shorter of the two may be used. The same applies to the distance Y in the vertical direction.

  Furthermore, as described above, the mouse operable range R does not have to be strictly defined. For example, the mouse operable range R is divided into the above-mentioned four vertices, the upper left vertex (L, U) and the upper right vertex (R). , U), the lower right vertex (R, L), and the lower left vertex (L, L). In this case, as can be seen from FIG. 2, the distance X and the distance Y can be calculated from the three vertices. Note that the remaining one vertex among the four vertices may be complemented based on the three.

  Further, the mouse operable range R may be determined by any two vertices that are diagonally located at the four vertices described above. In this case, as can be seen from FIG. 2, the distance X and the distance Y can be calculated based on the two vertices by complementing the remaining one of the four vertices.

  Further, as described above, the mouse operable range R does not have to be rectangular. For example, the mouse operable range R may be determined as a polygon having five or more vertices. In this case, the maximum rectangle inscribed in the polygon or the smallest rectangle inscribed in the polygon can be obtained, and the distance X and the distance Y can be calculated from the obtained rectangle.

  Furthermore, in any of the above cases, as shown in FIG. 8 described later, an input screen for each vertex may be displayed to the user.

  Next, the mouse movement ratio setting unit 13 calculates the mouse movement ratio as follows.

  The mouse movement ratio setting unit 13 refers to the ratio table 152 ′ using the resolution Z of the mouse 2. Thereby, the mouse movement ratio setting unit 13 acquires the reference horizontal movement ratio α and the reference vertical movement ratio β corresponding to the resolution Z of the mouse 2 from the ratio table 152 ′.

  FIG. 5 shows an example of the ratio table 152 '.

  The ratio table 152 ′ stores horizontal and vertical reference ratios, specifically, a reference horizontal movement ratio α and a reference vertical movement ratio β for each resolution Z of the mouse 2. The reference horizontal movement ratio α is a distance that the cursor moves in the horizontal direction in accordance with the movement of the mouse 2 by a unit distance in the horizontal direction. Therefore, the reference horizontal movement ratio α is a value that is uniquely determined based on the resolution Z of the mouse 2 and the horizontal resolution A of the display device 3. The reference vertical movement ratio β is a distance that the cursor moves in the vertical direction in response to the mouse 2 being moved in the vertical direction by a unit distance. Accordingly, the reference vertical movement ratio β is a value that is uniquely determined based on the resolution Z of the mouse 2 and the vertical resolution B of the display device 3.

  Accordingly, the reference horizontal movement ratio α is calculated in advance based on the resolution Z of the mouse 2 and the horizontal resolution A of the display device 3 and stored in the ratio table 152 ′ of the ratio table storage unit 132. The reference vertical movement ratio β is calculated based on the resolution Z of the mouse 2 and the vertical resolution B of the display device 3 and is stored in the ratio table 152 ′ of the ratio table storage unit 132.

  Thereafter, the mouse movement ratio setting unit 13 determines the horizontal distance X and the vertical distance Y, the screen resolutions A and B of the display device 3, the acquired reference horizontal movement ratio α and the reference vertical movement ratio β. Is used to calculate the mouse movement ratio.

  Specifically, the mouse movement ratio setting unit 13 calculates the horizontal movement ratio α ′ using the horizontal distance X, the horizontal resolution A of the screen of the display device 3, and the reference horizontal movement ratio α. For example, the horizontal movement ratio α ′ is calculated by α ′ = (A / X) × α. In addition, the mouse movement ratio setting unit 13 calculates the vertical movement ratio β ′ using the vertical distance Y, the vertical resolution B of the screen of the display device 3, and the reference vertical movement ratio β. For example, the vertical movement ratio β ′ is calculated by β ′ = (B / Y) × β.

  Next, the mouse movement ratio setting unit 13 sets the mouse movement ratio as follows.

  The mouse movement ratio setting unit 13 sends the calculated horizontal movement ratio α ′ and vertical movement ratio β ′ to the mouse control unit 16. The mouse control unit 16 stores the received horizontal movement ratio α ′ and vertical movement ratio β ′ in the movement ratio storage unit 162. Thereby, the mouse movement ratio used by the mouse control unit 16 is obtained in the movement ratio storage unit 162.

  For example, when the personal computer 1 is used, the user moves the mouse 2 within the mouse operable range R on the desk D. The mouse 2 transmits a movement signal indicating a relative movement amount in the horizontal direction and the vertical direction to the reception unit 11 at a predetermined time interval. The receiving unit 11 sends the received movement signal to the mouse control unit 16. Thereby, the mouse control unit 16 knows the relative movement amount of the mouse 2 in the horizontal direction and the vertical direction.

  Then, the mouse control unit 16 calculates the movement amount of the cursor on the screen of the display device 3 based on the movement amount of the mouse 2 and the mouse movement ratio. For example, the mouse control unit 16 reads the horizontal movement ratio α ′ from the movement ratio storage unit 162, and calculates the horizontal movement amount of the cursor by multiplying the horizontal movement amount of the mouse 2 and the horizontal movement ratio α ′. calculate. Further, the mouse control unit 16 reads the vertical movement ratio β ′ from the movement ratio storage unit 162, and calculates the vertical movement amount of the cursor by multiplying the vertical movement amount β ′ by the vertical movement ratio β ′ of the mouse 2. calculate. The mouse control unit 16 sends the calculated cursor movement amount to the display control unit 17.

  The display control unit 17 moves the cursor on the screen of the display device 3 based on the received movement amount of the cursor. Thereby, even if the mouse operable range R changes, the cursor can be moved anywhere on the screen of the display device 3 without lifting the mouse 2, and the mouse 2 can be operated intuitively. it can.

Is acquired, and the acquired position information of the lower right vertex (R, L) is held.

  Thereafter, the mouse movement ratio setting unit 13 reads the lower left vertex input confirmation screen from the screen storage unit 131 and requests the display control unit 17 to display it. In response to this, the display control unit 17 displays the requested lower left vertex input confirmation screen on the display device 3 (step S17). FIG. 8E shows an example of the upper right vertex input confirmation screen.

  The user of the personal computer 1 viewing the lower left vertex input confirmation screen presses the trigger switch of the mouse 2 at the lower left vertex (L, L) of the mouse operable range R (step S18). When the trigger switch of the mouse 2 is pressed while the lower left vertex input confirmation screen is displayed, the mouse movement ratio setting unit 13 causes the mouse position measurement unit 15 to display the position of the lower left vertex (L, L) of the mouse operable range R. Information is acquired, and the acquired position information of the lower left vertex (L, L) is held.

  Next, the mouse movement ratio setting unit 13 determines whether or not the position information of the four vertices of the mouse operable range R has been input (step S19). When the position information of the four vertices is not input (No at Step S19), the mouse movement ratio setting unit 13 repeats Step S11.

  When the position information of the four vertices is input (Yes in step S19), the mouse movement ratio setting unit 13 determines the horizontal distance X of the mouse operable range R based on the position information of the four vertices, The distance Y in the vertical direction is acquired (step S110), and the acquired distance X in the horizontal direction and distance Y in the vertical direction are held.

  Next, as shown in FIG. 9, the mouse movement ratio setting unit 13 executes a movement ratio setting process for the mouse 2 (step S111). When the mouse movement ratio setting unit 13 finishes the mouse 2 movement ratio setting process, the mouse movement ratio setting unit 13 reads an end screen of the mouse 2 movement ratio setting process from the screen storage unit 131 and requests the display control unit 17 to display it. In response to this, the display control unit 17 displays the requested end screen on the display device 3 (step S112). FIG. 8F shows an example of the end screen.
