Description

  The present invention relates to an information processing apparatus and method, a program, and a recording medium, and more particularly, to an information processing apparatus and method, a program, and a recording medium that improve user convenience and allow a desired processing result to be obtained quickly and accurately. .

  When setting or changing the layout of an image to be displayed in a word processor program, a spreadsheet program, or the like, the user inputs a predetermined numerical value in a dialog box 1 as shown in FIG. change. At this time, on the display screen of the computer on which the dialog box 1 is displayed, clicking the button 11 or 12 arranged on the right side of the dialog box 1 with the mouse causes the numerical value to be counted up or down. The display is controlled.

  However, when creating a drawing using a CAD (Computer Aided Design) device, etc., as shown in FIG. 2, a desired numerical value is entered in each of the dialog boxes 21, 22, 23,. In many cases, a numerical value to be input is a numerical value having a large number of digits. For this reason, the user selects the buttons 31, 32, 33,... Arranged on the right side of the dialog boxes 21, 22, 23,. Must be clicked until the desired value is reached, and a cumbersome operation is required.

  Therefore, in CAD, in order to facilitate the input of such numerical values, a control method is used in which the numerical value is counted up or down by rotating the center wheel which is a disk provided between the buttons of the mouse. It is done. In such a case, the user does not need to click the buttons 31, 32, 33,..., The mouse pointer is set to the dialog boxes 21, 22, 23,. The numerical values in the dialog boxes 21, 22, 23,... Can be counted up or down by simply rotating them, but at this time, how much the numerical value is relative to the rotation amount (rotation angle) of the center wheel. It is important to count up or down. Here, the center wheel of the mouse is normally configured to change the rotation angle by, for example, 20 degrees as a unit of rotation amount. Hereinafter, the unit of the stepwise rotation amount of the center wheel is referred to as “notch”.

  In such a case, for example, if the count-up or count-down amount per notch of the center wheel of the mouse is set large, the numerical value can be greatly counted up or down with a small amount of rotation, so that a quick operation is possible. On the other hand, the operation of finely adjusting the numerical value becomes difficult. Also, if the count-up or count-down amount per notch of the center wheel is set small, the amount of numerical values counted up or down can be reduced even with the same rotation amount, so that fine adjustment of the numerical value becomes easy. On the other hand, in order to display a desired numerical value, it is necessary to rotate the center wheel many times, and a quick operation cannot be performed.

Therefore, a technique has been proposed in which the amount of rotation of the center wheel is detected and a scroll (count up or count down) amount corresponding to the amount of rotation is set (see, for example, Patent Document 1).
JP 2003-029925 A

Correspondingly, it is possible to control the input numerical value to be counted up or down based on the count up amount or count down amount set by the setting means.

  Embodiments of the present invention will be described below with reference to the drawings. FIG. 3 is a block diagram showing an embodiment of the information processing apparatus 100 to which the present invention is applied. This information processing apparatus is configured as a personal computer, for example. The main body 121 is a computer having a CPU (Central Processing Unit) and the like, and a detailed configuration thereof will be described later with reference to FIG. The display 122 connected to the main body 121 is configured by an LCD (Liquid Crystal display) or the like, and displays an image based on a signal output from the main body 121. In addition, the main body 121 includes a keyboard 123 used for inputting predetermined numerical values or characters, and a mouse used for moving a cursor, a pointer, and the like to predetermined portions in an image (screen) displayed on the display. 124 is connected.

Alternatively, characters or numerical values are input using the mouse 124, and the screen displayed on the display 122 is enlarged, reduced, or scrolled.

  FIG. 4 is a block diagram illustrating a detailed configuration example of the mouse 124. The mouse 124 is a pointing device that controls display of a pointer, a cursor, and the like on the display 122 in response to a user operation. In this example, the mouse 124 is centered between the left click button 142 and the right click button 143 of the mouse 124. A wheel 141 is provided. The center wheel 141 is configured in a disk shape, for example, and is configured to be rotated in the direction of the arrow 151 or the direction of the arrow 152 in a state where the rotation shaft is fixed to the mouse 124 body. The configuration of the center wheel 141 is not limited to this, and may be provided on the mouse and configured to be moved in the vertical direction (or left and right) by the user.

  The center wheel 141 is operated to perform screen enlargement, reduction, scrolling, and count-up (or count-down) of numerical values input to a predetermined input area according to an application executed by the information processing apparatus 100. The mouse 124 outputs a predetermined signal (command) to the main body 121 as the center wheel 141 rotates. For example, when the user moves (rotates) the center hole 141 with a finger in the direction of the arrow 151, a signal for controlling the screen to scroll upward (the upper side of the screen is displayed) is output. When it is rotated in the direction of the arrow 152, a control signal is output so that the screen is scrolled downward (the lower side of the screen is displayed).

  FIG. 5 is a block diagram illustrating a configuration example of the main body 121. In the figure, a CPU (Central Processing Unit) 201 executes various processes according to a program stored in a ROM (Read Only Memory) 202 or a program loaded from a storage unit 208 to a RAM (Random Access Memory) 203. To do. The RAM 203 also appropriately stores data necessary for the CPU 201 to execute various processes.

  The CPU 201, the ROM 202, and the RAM 203 are connected to each other via the bus 204. An input / output interface 205 is also connected to the bus 204.

  The input / output interface 205 includes an input unit 206 including the keyboard 123 and mouse 124 described above, an output unit 207 including the display 122 and speakers described above, a storage unit 208 including a hard disk, a modem, a terminal adapter, and the like. A communicator 209 is connected.

  The communication unit 209 performs communication processing with other devices via a network such as the Internet. The storage unit 208 appropriately stores programs such as application software, data generated by processing executed by the programs, and the like.

  A drive 210 is also connected to the input / output interface 205 as necessary. For example, a removable medium 211 is mounted on the drive 210 as a recording medium on which the program of the present invention is recorded, and read from them. A computer program is installed in the storage unit 208 as necessary.

  FIG. 6 is a block diagram illustrating a functional configuration example of the CPU 201 that executes the mouse input control program. An operating system 223 is installed in the information processing apparatus 100, and the operating system 223 includes a mouse input control program 231. In addition, an application program 221 is installed on the operating system 223, and a mouse interface unit 222 that controls input / output (exchange) of information between the mouse input control program 231 and the application program 221 is installed in the application program 221. It is included.

  The mouse input control program 231 includes an input control unit 232 and an operation speed detection unit 233. The input control unit 232 receives information (signals) input by the user using the mouse 124 and outputs the information (signal) to the mouse interface unit 222. When the center wheel 141 is moved (for example, rotated), the operation speed detection unit 233 operates based on a command from the input control unit 232 (in this case, the rotation speed). Is output to the input control unit 232.

  Next, a numerical value input process for inputting a numerical value using the mouse 124 in the application executed by the information processing apparatus 100 will be described with reference to a flowchart of FIG. Through this process, a predetermined command may be input to the application program being executed, or a numerical value may be input.

  In step S <b> 1, the mouse interface unit 222 specifies a numerical input location (variable) where a numerical value is input by operating the mouse 124, and outputs information on the specified position to the input control unit 232.

  At this time, for example, the dialog box 251 shown in FIG. 8 is specified as a numerical value input location. In other words, by specifying the dialog box 251, the variable to which the value is set is specified by the operation of the dialog box 251.

  The dialog box 251 is a dialog box in which a numerical value for specifying the item “height” is input in an application such as CAD, and in this case, a numerical value “2570” is input. For example, the user specifies the dialog box 251 as a numerical value input location by operating the mouse 124 to match the position of the pointer displayed on the display 122 with the position of the dialog box 251. Then, as will be described later, by operating the center wheel 141, the numerical value of the dialog box 251 can be counted up (incremented) or counted down (decremented).

  Alternatively, for example, a numerical value input location may be input on a display screen as shown in FIG. FIG. 9 is a diagram illustrating an example of a screen displayed when the button 252 arranged on the right side of the dialog box 251 in FIG. 8 is clicked by the left click button 142 of the mouse 124, for example. In this example, a dialog box in which a numerical value is input is divided into five boxes for each numerical digit, and are designated as boxes 254-1 to 254-5.

  In this case, numerical values “0”, “2”, “5”, “7”, “0” are entered in the boxes 254-1 to 254-5, respectively, and the item “ In a numerical value box 255 for designating “height”, a numerical value “2570 (mm)” is displayed.

  For example, the user operates the mouse 124 to adjust the position of the pointer to one of the boxes 254-1 to 254-5, thereby setting any one of the boxes 254-1 to 254-5 as a numerical value input location. Identify. Then, as will be described later, by operating the center wheel 141, the numerical values in the dialog boxes 254-1 to 254-5 can be counted up or down. For example, when the box 254-2 is specified as the input position, by rotating the center wheel 141 in the direction of the arrow 151, only the numerical value of the box 254-2 is changed to “3”, “4”, “ 5 ”,... Can be counted up.

  Note that when the button 253 representing accepting direct input of a numerical value is clicked (turned on), numerical values in the boxes 254-1 to 254-5 are input by rotating the center wheel 141. The input is not controlled so that the input of the numerical value is received, but the numerical value is directly input by the keyboard 123 or the like, so that the input of the numerical value is received.

  Returning to FIG. 7, after the process of step S <b> 1, the process proceeds to step S <b> 2, and the operation speed detection unit 233 detects the operation speed (rotation speed in this case) of the center wheel 141. Perform detection processing.

  Here, the details of the center wheel rotation speed detection process in step S2 of FIG. 7 will be described with reference to the flowchart of FIG. In step S21, the operation speed detection unit 233 determines whether or not the first notch of the center wheel 141 has been detected (whether or not the center wheel 141 has been rotated by one notch), and until it is determined that it has been detected. stand by. In addition, in order to detect the rotation degree (angle) of the center wheel 141, the drive mechanism (for example, the rotation axis of the center wheel 141) of the center wheel 141 has a notch, for example, cut every 20 degrees. When the center wheel 141 is rotated by one notch or indentation, the rotation of one notch is detected. That is, here, the notch is used as a unit representing the stepwise rotation amount of the center wheel 141.

  If it is determined in step S21 that the first notch of the center wheel 141 has been detected, the process proceeds to step S22, and the operation speed detection unit 233 stores the time t1 at this time. Note that, for the time t1, time information output from, for example, a timer built in the information processing apparatus 100 is acquired and stored.

  Specifically, the time t1, which is the current time, is acquired and stored. Alternatively, the timer may be reset, and the time t1, which is the reset time, may be acquired and stored.

  After the process of step S22, in step S23, the operation speed detector 233 determines whether a predetermined number (for example, 3) of notches has been detected, and waits until it is determined that the predetermined notches have been detected. To do.

  If it is determined in step S23 that a predetermined number of notches have been detected, the process proceeds to step S24, and the operation speed detection unit 233 stores the time t2 at this time.

  In step S25, the operation speed detector 233 calculates time T = t2-t1, and in step S26, calculates the rotation speed (= number of notches / T). Time t1 is the time when the first notch is detected, and time t2 is the time when a predetermined number (eg, 3) of notches are detected after time t1. Therefore, the time T (= t2-t1) is the time required for the center wheel 141 to rotate by 3 notches, and the rotation speed of the center wheel 141 is calculated by dividing the number of notches (3) by the time T. Is done.

  Further, the rotational speed (operation speed) of the center wheel 141 may be calculated by another method. FIG. 11 is a flowchart for explaining another example of the center wheel rotation speed detection process.

  That is, in step S41, the operation speed detection unit 233 starts a timer. Here, for example, the operation speed detection unit 233 detects the elapse of a predetermined time (for example, 3 seconds) by acquiring time information output from another timer built in the information processing apparatus 100 or the like. Is a timer owned by

  In step S42, the operation speed detection unit 233 initializes the variable N representing the rotation amount (the number of notches) of the center wheel 141 by setting a value 0.

  In step S43, the operation speed detection unit 233 determines whether rotation (one notch) of the center wheel 141 has been detected, and waits until it is determined that it has been detected. If it is determined in step S43 that the rotation (one notch) of the center wheel 141 has been detected, the process proceeds to step S44, and the operation speed detection unit 233 increments the value of the variable N by one.

  In step S45, the operation speed detection unit 233 (the timer thereof) determines whether or not the predetermined time T has elapsed. If it is determined that the predetermined time T has not yet elapsed, the process returns to step S43. The subsequent processing is repeatedly executed. As a result, the number of notches detected until the time T elapses is updated as the value of the variable N.

  When it is determined in step S45 that the predetermined time T has elapsed, the operation speed detection unit 233 calculates the rotation speed (= N / T) in step S46.

  In this way, the amount of rotation of the center wheel 141 per unit time, that is, the rotation speed (operation speed) of the center wheel 141 is detected (calculated).

  Returning to FIG. 7, in step S3, the input control unit 232 sets a count-up amount (or count-down amount) per notch corresponding to the rotational speed of the center wheel 141 detected in the process of step S2. At this time, the count-up amount (or count-down amount) per notch of the rotation amount of the center wheel 141 is used as a parameter of a command for controlling the count-up (or count-down) of the numerical value output by rotating the center wheel 141. Is set. Then, the set count-up amount (or count-down amount) per notch is output to the mouse interface unit 222.

  The count-up amount per notch is set in advance as shown in the graph of FIG. 12, for example. In this example, the count-up amount (vertical axis) set with respect to the rotation speed (horizontal axis) of the center wheel 141 is indicated by a line graph. As shown in the figure, when the rotation speed of the center wheel 141 is 1 (notch / second) or less, the count-up amount (or count-down amount) per notch of the rotation amount of the center wheel 141 is set to 1. . Further, when the rotation speed of the center wheel 141 exceeds 1 (notch / second) and is 2 (notch / second) or less, the count-up amount (or count-down amount) per notch of the rotation amount of the center wheel 141 is 2. When the rotation speed of the center wheel 141 is set to exceed 2 (notch / second) and equal to or less than 3 (notch / second), the count-up amount (or count-down amount) per notch of the rotation amount of the center wheel 141 is 3 Set to

  That is, when the center wheel 141 is rotated slowly, the count-up amount of the input numerical value is set to be smaller than the rotation amount of the center wheel 141, and when the center wheel 141 is quickly rotated, the center wheel The count-up amount of the input numerical value is set to be larger than the rotation amount of 141.

  In this example, the count-up amount (vertical axis) set with respect to the rotational speed (horizontal axis) of the center wheel 141 is shown by a line graph, but the rotational speed (horizontal axis) of the center wheel 141 is On the other hand, the count-up amount (vertical axis) that is set may be changed in more detail so as to be indicated by a straight line. In this case, the count-up amount set with respect to the rotation speed of the center wheel 141 is a straight line that rises to the right in the figure, and the slope of the straight line is preset as the count-up amount per notch. As described above, by gradually changing the count-up amount corresponding to the rotation speed of the center wheel 141, the optimum count-up amount for the user is automatically set every time the center wheel 141 is operated.

  Of course, the count-up amount (vertical axis) set for the rotational speed (horizontal axis) of the center wheel 141 may be indicated by a curve such as an exponential function.

  After the process of step S3, the process proceeds to step S4, and the mouse interface unit 222 determines that the center wheel 141 is based on the numerical value input location detected in step S1 and the count-up amount (or count-down amount) set in step S3. In accordance with this rotation, the numerical value input in the box 254-2 (or dialog box 251) is counted up (or counted down).

  In step S5, the input control unit determines whether or not a predetermined time has elapsed. If it is determined that the predetermined time has not yet elapsed, the process returns to step S4. On the other hand, if it is determined that the predetermined time has elapsed, the process returns to step S2, and the rotational speed of the center wheel 141 is newly detected. The subsequent processing is repeatedly executed.

  In this way, the numerical value is counted up or down in accordance with the rotation speed (operation speed) of the center wheel 141. In this way, for example, when the user wants to quickly count up the numerical value input in the box 254-2 in FIG. 9 (or the dialog box 251 in FIG. 8), the pointer of the mouse 124 is moved to the box 254. -2 (or dialog box 251), the center wheel 141 is quickly rotated in the direction of arrow 151 to quickly count up the numerical value input in box 254-2 (or dialog box 251), It is possible to immediately count up to a desired numerical value or a numerical value close to the desired numerical value.

  For example, when the numerical value in the box 254-2 (or dialog box 251) is already a numerical value close to a desired numerical value, the user moves the pointer of the mouse 124 to the box 254-2 (or dialog box 251). By rotating the center wheel 141 slowly in the direction of the arrow 151, the numerical value input to the box 254-2 (or the dialog box 251) can be slowly counted up, and the numerical value can be finely adjusted.

  Next, a drawing enlargement / reduction process for enlarging or reducing the drawing using the center wheel 141 of the mouse 124 in an application such as CAD will be described with reference to the flowchart of FIG. This processing is automatically executed when the drawing is enlarged or reduced using the mouse 124 in association with execution of an application such as CAD.

  In step S <b> 71, the mouse interface unit 222 detects the center position of the portion to be enlarged or reduced in the screen displayed on the display 122 and outputs the detected position to the input control unit 232.

  For example, when a drawing as shown in FIG. 14 is displayed on the display 122 and the user enlarges the drawing, the user operates the mouse 124 to specify the position of the pointer in the drawing, and the pointer The position 301 specified by is detected as the center position. Thereafter, when the center wheel 141 is rotated in the direction of the arrow 151, for example, a signal (command) for controlling the enlargement of the screen is output. When the position 301 is detected, the position 301 is automatically moved to the center of the screen displayed on the display 122 by the CAD function, and then the user is surrounded by a frame 302 around the position 301. It is assumed that the range to be displayed is operated to be enlarged and displayed on the display 122.

  After the process of step S71, the process proceeds to step S72, and the operation speed detection unit 233 executes a center wheel rotation speed detection process for detecting the operation speed of the center wheel 141 (in this case, the rotation speed). Since this process is the same as the process described above with reference to FIG. 10 or FIG. 11, a detailed description is omitted, but the rotational speed (operation speed) of the center wheel 141 is thereby detected.

  In step S73, the input control unit 232 sets an enlargement rate (or reduction rate) per notch corresponding to the rotation speed of the center wheel 141 detected in the process of step S72. In the process of step S3 in FIG. 7, the count-up amount (or count-down amount) per notch of the rotation amount of the center wheel 141 is set. In this case, the center wheel 141 as shown in FIG. 15 is rotated. As a parameter of a command for controlling the enlargement (or reduction) of the screen output by this, the enlargement rate (or reduction rate) per notch of the rotation amount of the center wheel 141 is set. Then, the set enlargement rate (or reduction rate) per notch is output to the mouse interface unit 222.

  In the example of FIG. 15, the enlargement ratio (vertical axis) set with respect to the rotation speed (horizontal axis) of the center wheel is shown by a line graph. As shown in the figure, when the rotation speed of the center wheel 141 is 1 (notch / second) or less, the enlargement rate (or reduction rate) per notch of the rotation amount of the center wheel 141 is set to 10%. . When the rotation speed of the center wheel 141 exceeds 1 (notch / second) and is 2 (notch / second) or less, the enlargement ratio (or reduction ratio) per notch of the rotation amount of the center wheel 141 is 20%. When the rotation speed of the center wheel 141 is set to exceed 2 (notch / second) and equal to or less than 3 (notch / second), the enlargement rate (or reduction rate) per notch of the rotation amount of the center wheel 141 is 30%. Set to

  That is, when the center wheel 141 is slowly rotated, the screen enlargement ratio is set to be smaller than the rotation amount of the center wheel 141. When the center wheel 141 is quickly rotated, the rotation amount of the center wheel 141 is set. On the other hand, the enlargement ratio of the screen is set to be large.

  In this example, the enlargement ratio (vertical axis) set with respect to the rotational speed (horizontal axis) of the center wheel 141 is shown by a line graph, but the rotational speed (horizontal axis) of the center wheel 141 is shown. The enlargement ratio (vertical axis) set in this way may be changed in more detail and shown as a straight line. In this case, the enlargement ratio set with respect to the rotation speed of the center wheel 141 is a straight line rising to the right in the figure, and the inclination of the straight line is preset as the enlargement ratio per notch. As described above, by gradually changing the enlargement ratio corresponding to the rotation speed of the center wheel 141, the optimum enlargement ratio for the user is automatically set every time the center wheel 141 is operated.

  Of course, the enlargement ratio (vertical axis) set for the rotational speed (horizontal axis) of the center wheel 141 may be represented by a curve such as an exponential function.

  After the processing of step S73, the process proceeds to step S74, and the mouse interface unit 222 rotates the center wheel 141 based on the center position detected in step S71 and the enlargement ratio (or reduction ratio) set in step S73. The screen is enlarged (or reduced) according to.

  In step S75, the input control unit 232 determines whether or not a predetermined time has elapsed. If it is determined that the predetermined time has not elapsed, the process returns to step S74. On the other hand, if it is determined that the predetermined time has elapsed, the process returns to step S72, and the rotational speed of the center wheel 141 is newly detected. The subsequent processing is repeatedly executed.

  In this manner, the screen (the drawing displayed on the display 122) is enlarged or reduced in accordance with the rotation speed (operation speed) of the center wheel 141. In this way, for example, when the user wants to quickly enlarge the portion surrounded by the frame 302 in FIG. 14, the pointer of the mouse 124 is aligned with the position 301 and the center wheel 141 is moved in the direction of the arrow 151. By rotating quickly, the portion surrounded by the frame 302 can be quickly enlarged.

  FIG. 16 is a diagram illustrating an example of a screen displayed on the display 122 at this time. In the figure, a position 301 is located at the center of the screen, and the portion surrounded by a frame 302 is enlarged until it is substantially equal to the size of the screen.

  After enlarging the screen to this state, the user slowly rotates the center wheel 141 in the direction of the arrow 151 to slowly enlarge the screen displayed on the display 122 and fine-adjust the frame 302. The screen can be enlarged until it is equal to the screen size.

  Next, with reference to a flowchart of FIG. 17, a scroll process for scrolling the drawing using the center wheel 141 of the mouse 124 in the application executed by the information processing apparatus 100 will be described. This process may be automatically executed when the drawing is scrolled using the mouse 124 with the execution of the application program, for example.

  In step S <b> 101, the mouse interface unit 222 detects the scroll start position in the screen displayed on the display 122 and outputs the detected position to the input control unit 232.

  For example, when an application such as a spreadsheet program is being executed, a screen as shown in FIG. 18 is displayed on the display 122, and the user operates the mouse 124 to point to any position in this screen. This position (the position of the table on the screen) is detected as the scroll start position. In the figure, a table created using an application such as a spreadsheet program is displayed on the screen. The number of rows (serial number) is displayed at the left end of the table. In this example, the 4902th to 4926th rows of the table are displayed.

  In this state, for example, when the center wheel 141 is rotated in the direction of the arrow 152, a signal (command) for controlling the screen to be scrolled downward in the figure is output, and the position displayed on the screen is the lower side in the figure. Move in the direction. That is, the screen disappears from the screen in order from the 4902th line of the table, and is scrolled to be displayed on the screen in order from the 4927th line of the table. Conversely, when the center wheel 141 is rotated in the direction of the arrow 151, the table scrolls upward in the figure.

  After the process of step S101, the process proceeds to step S102, and the operation speed detection unit 233 executes a center wheel rotation speed detection process for detecting the operation speed of the center wheel 141 (in this case, the rotation speed). Since this process is the same as the process described above with reference to FIG. 10 or FIG. 11, a detailed description is omitted, but the rotational speed (operation speed) of the center wheel 141 is thereby detected.

  In step S103, the input control unit 232 sets a scroll amount per notch corresponding to the rotation speed of the center wheel 141 detected in the process of step S102. In the process of step S3 in FIG. 7, the count-up amount (or count-down amount) per notch of the rotation amount of the center wheel 141 is set. In this case, the center wheel 141 as shown in FIG. 19 is rotated. As a parameter of the command for controlling the scrolling of the screen that is output, the scroll amount per notch of the rotation amount of the center wheel 141 is set. Then, the set scroll amount per notch is output to the mouse interface unit 222.

  In the example of FIG. 19, the scroll amount (vertical axis) set with respect to the rotation speed (horizontal axis) of the center wheel is shown by a line graph. As shown in the figure, when the rotation speed of the center wheel 141 is 1 (notch / second) or less, the scroll amount per notch of the rotation amount of the center wheel 141 is set to one line. Further, when the rotation speed of the center wheel 141 exceeds 1 (notch / second) and is 2 (notch / second) or less, the scroll amount per notch of the rotation of the center wheel 141 is set to 2 lines. When the rotation speed of 141 exceeds 2 (notch / second) and is 3 (notch / second) or less, the scroll amount per notch of the rotation amount of the center wheel 141 is set to 3 rows.

  That is, when the center wheel 141 is slowly rotated, the screen scroll amount is set to be smaller than the rotation amount of the center wheel 141. When the center wheel 141 is quickly rotated, the rotation amount of the center wheel 141 is set. On the other hand, the screen scroll amount is set to be large.

  In this example, the scroll amount (vertical axis) set with respect to the rotational speed (horizontal axis) of the center wheel 141 is indicated by a line graph, but with respect to the rotational speed (horizontal axis) of the center wheel 141. The scroll amount (vertical axis) set in this way may be changed in more detail and shown as a straight line. In this case, the scroll amount set with respect to the rotation speed of the center wheel 141 is a straight line rising to the right in the figure, and the inclination of the straight line is preset as the scroll amount per notch. As described above, by gradually changing the scroll amount in accordance with the rotation speed of the center wheel 141, an optimum enlargement factor for the user is automatically set every time the center wheel 141 is operated.

  Of course, the scroll amount (vertical axis) set for the rotational speed (horizontal axis) of the center wheel 141 may be indicated by a curve such as an exponential function.

  After the process of step S103, the process proceeds to step S104, and the mouse interface unit 222 adjusts the rotation of the center wheel 141 based on the scroll start position detected in step S101 and the scroll amount set in step S103. Scroll the screen.

  In step S105, the input control unit 232 determines whether or not a predetermined time has elapsed. If it is determined that the predetermined time has not elapsed, the process returns to step S104. On the other hand, if it is determined that the predetermined time has elapsed, the process returns to step S102, and the rotational speed of the center wheel 141 is newly detected. The subsequent processing is repeatedly executed.

  In this way, the screen (displayed on the display 122 and the table) is scrolled in accordance with the rotation speed (operation speed) of the center wheel 141. In this way, for example, when it is desired to quickly display a desired row, the table can be quickly scrolled to the vicinity of the desired row by quickly rotating the center wheel 141 in the direction of the arrow 151 or 152. it can.

  In addition, when a portion close to a desired row is already displayed in the table, the user slowly scrolls the table by slowly rotating the center wheel 141 in the direction of the arrow 151 or 152, and the desired row is displayed. Can be reliably displayed at a desired position on the screen.

  It does not matter whether the above-described series of processing is realized by hardware or software. When the above-described series of processing is executed by software, a program constituting the software is installed from a recording medium such as a network or the removable medium 211.
