The proper cursor moving speed at the coordinate position can optionally be varied based the displacement amount, so that operation is easily performed.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information processing apparatus with a joystick in which a cursor operation for pointing arbitrary coordinates on a display device is naturally performed at the operator's will.

[0002]

2. Description of the Related Art In a conventional information processing apparatus with a joystick, a lever is rotated in a positive direction and a negative direction about a neutral position, so that the X-axis and Y from the neutral position to the position where the lever is operated. A displacement amount corresponding to the coordinate value of the axis is defined in the ROM as a basic table shown in FIG. The cursor on the display device operates based on the displacement of the basic table corresponding to the operation position of the joystick.

[0003]

In the conventional information processing apparatus with a joystick as described above, as shown in FIG.
If the integer value is increased because the basic table indicated by is simply multiplied by an integer, the cursor moves as the position where the lever is operated moves away from the neutral position, that is, as the coordinate values X and Y increase. Because the moving speed of is too fast, the cursor cannot be moved minutely.

[0004]

SUMMARY OF THE INVENTION The present invention is intended to solve these problems and is provided on a display device in accordance with a lever operation which is rotated in a positive direction and a negative direction around a predetermined neutral position. In the information processing device with a joystick for moving the cursor, the coordinate values X and Y indicating the position where the lever is operated are read, and the lever is operated from the neutral position from the coordinate values X and Y. (EN) An information processing device with a joystick in which a displacement amount to a position is obtained and a cursor moving speed can be arbitrarily changed according to the displacement amount at the read coordinate position.

[0005]

From the neutral position where the X and Y coordinate addresses are zero, the X and Y coordinate addresses that indicate the coordinate values of the lever that is rotated in all directions in the positive direction and / or the negative direction are read, and the coordinate values are read. The amount of displacement up to the neutral position is calculated, and the appropriate cursor movement speed at that coordinate position can be arbitrarily changed based on the amount of displacement, so that the operator can move the cursor naturally and at will. Can be seen.

Since the table of FIG. 3 corresponds to the shaded area obtained by dividing the coordinates of FIG. 2 into four, there are four such tables for each coordinate section, and the movement values in the X-axis direction and the Y-axis direction are neutral. It is relatively divided into four stages from the position (0, 0). FIG. 4 shows the relative movement value in the X-axis direction and the Y-axis based on the relative movement value in the X-axis direction and the Y-axis direction set in FIG.
The relative movement value in the axial direction is squared, and the sum thereof is squared to obtain the distance from the neutral position (0, 0) in the diagonal direction at the coordinate position of each of the X-axis and Y-axis positions. Has become. The table in FIG. 6 corresponds to the angle θ of the operation unit 18 when the diagonal distance obtained in FIG. 4 is rotated from the neutral position, so that the cursor speed changeover switch 17 corresponding to the angle θ is used. The cursor movement speed is defined for each of the three modes. At the cursor movement speed at the position defined as "1" in the table, it takes, for example, 26 seconds until the cursor moves from one end of the screen of the display device 25 to the other. The higher the value, the faster the cursor moving speed. In that case, at the cursor movement speed at the position defined as "4", it takes 26/4 seconds until the cursor (not shown) moves from one end of the screen of the display device 25 to the other. In the table of FIG. 7, if the cursor is moved only in the X-axis direction or only in the Y-axis direction, the value of the cursor movement speed defined in the table of FIG. 6 is set. In the "low speed" mode, when the cursor moves only in the X-axis direction, the Y-axis value is "0".
Is defined, and the value of the X-axis is “1”, “2”, “4”, “6” based on the angle θ defined in the table of FIG.
Is set. X when moving the cursor only in the Y-axis direction
The value of the axis is defined as “0”, and the value of the Y axis is defined as “1”, “2”, based on the angle θ defined in the table of FIG.
“4” and “6” are set. The values of X and Y at the diagonal position are calculated and obtained based on the flowchart of FIG. However, the calculation result is the first decimal point.
Rounded to the nearest place. Below, "medium speed", "high speed"
The mode is obtained by the same method. Figure 8
The table is set so that the cursor can be moved more finely based on the values in the table of FIG.

The operation will be described with reference to FIGS. 1 to 9. In FIG. 1, a first ROM 11 shown in FIGS.
The tables shown in FIGS. 8 to 8 and the programs created based on the flowcharts shown in FIGS. 5 and 9 are stored. The operation unit 18 of the joystick 13 is defined as a neutral state when it is in a vertical state as shown in FIG. 1, an X-axis direction when the operation direction moves to the left and right, and a Y-axis direction when it moves from the front to the back. ing. When an operation is performed while inclining the operation portion 18 of the joystick 13 in order to move the cursor displayed on the display device 25 to a desired position, the program created based on the flowchart of FIG. Actions are performed. The X-axis and Y-axis coordinate values corresponding to the tilt angle of the joystick 13 are read (step 1), and the contents are stored in the first RAM 12. Next, the state of the cursor speed changeover switch 17, which can set the cursor moving speed to three kinds of speeds such as "low speed", "medium speed", and "high speed", is read (step 2), and the state is the first. Stored in the RAM 12. Whether the switch state is "low speed" is compared (step 3), and if the mode is the "low speed" mode, the "low speed" column shown in FIG. 7 is referred to (step 7). Next, it is compared whether or not the switch state is "medium speed" (step 4), and if it is the "medium speed" mode, the "medium speed" column shown in FIG. 7 is referred to (step 6). . For modes other than the above, refer to the "high speed" column shown in FIG. 7 (step 5). Further, referring to the table of FIG. 7 based on the X-axis and Y-axis coordinate values stored in the RAM 12, the cursor movement speed values corresponding to the X-axis and Y-axis coordinate values obtained from the table. The cursor moving speed is determined by referring to the table of FIG.

For example, when the cursor speed changeover switch 17 is in the "medium speed" mode, the operating portion 18 has an angle θ of 12 to 18 degrees in the X-axis direction and an angle θ of 18 to 24 in the Y-axis direction.
Assuming that the joystick 13 is tilted from the neutral position, the "medium speed" mode is referred to in the table of FIG. 7, the moving speed of the X-axis cursor is "10", and the moving speed of the Y-axis cursor is "14" is selected as the moving speed, the moving data is sent to the main body 20 via the serial interface 19 shown in FIG. 1 (step 8), and the main body 20 moves the cursor based on the notification information from the remote controller 10. Is done. The locus along which the cursor moves based on the table of FIG. 7 is shown in FIG. 10. In this case, however, the cursor is relatively fast moving in the oblique direction. Therefore, FIG. 8 shows a table in which correction is performed to reduce the moving speed of the cursor by about 10% in the ± 45 ° direction and ± 135 ° direction, and the trajectory of the cursor movement based on this table is As shown in FIG. 11, it can be seen that a smooth trajectory is drawn.

When the joystick 13 starts to be tilted from the neutral position in this way, the cursor speed gradually accelerates according to the tilt, and when the cursor approaches the desired position, the joystick 13 tries to return to the neutral position. Due to the force, the cursor speed becomes slower according to the inclination. Therefore, an information processing device with a joystick that is easy to use can be provided.

As described above, according to the present invention, the coordinate value of the joystick and the displacement amount to the neutral position are calculated, and the appropriate cursor movement speed at the coordinate position can be arbitrarily changed based on the displacement amount. Even when the operator wants to move the cursor to a desired position, the cursor performs a natural operation as the operator desires.
