2. Description of the Related Art Conventionally, in an information processing apparatus such as a personal computer, a display screen of the information processing apparatus includes:
A cursor or pointer for indicating a data input position, a data selection position, or the like on the display screen is displayed. The operation of moving the cursor or pointer is performed by a key operation of a cursor key provided on a keyboard or a mouse or a trackball. This is performed in response to a ball rotation operation.

That is, the cursor moves at a distance corresponding to the key operation time of the cursor key, and the pointer moves at a distance corresponding to the operation distance of the mouse or the like. The pointer is moved at a constant interval for each key sampling, and the pointer is moved at a constant interval for each predetermined amount of ball rotation by a mouse or the like.

Here, if the cursor moving distance at a certain interval accompanying the key sampling of the cursor key is set to be long, the cursor moving distance becomes long even with the same key operation time, and the cursor moves apparently at high speed. The operation can be performed, but in order to perform the high-speed operation for moving the cursor, the high-speed movement mode of the cursor must be set for exclusive use.

[0005] Further, if the pointer movement distance at a constant interval according to the ball rotation amount of the mouse or the like is set to be long, the pointer movement distance becomes longer even with the same ball rotation amount (mouse movement amount), and the apparent distance is increased. Although the pointer can be moved at high speed, the high-speed movement of the pointer must be performed after setting a dedicated pointer high-speed movement mode.

[0006]

Therefore, in the cursor movement function and the pointer movement function in the conventional information processing apparatus, if a high-speed movement operation is desired, the high-speed movement mode must be set in advance. In addition to the troublesome operation, there is a problem that real-time high-speed moving display cannot be performed.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-described problems, and does not require the operation and setting of the high-speed movement mode in advance. The purpose is to provide.

[0008]

That is, a display device according to the present invention is a display device for displaying a pointer on a display screen, comprising: movement instruction means for instructing the movement of the pointer; and movement of the pointer. When the movement of the pointer is instructed by the speed instructing means for instructing the speed and the movement instructing means, and when the moving speed of the pointer is instructed by the speed instructing means, the pointer is moved at the instructed speed. And a movement control means.

That is, in the display device according to the present invention, when the movement of the pointer is instructed by, for example, a mouse operation, and when the high-speed movement of the pointer is instructed by speed instructing means such as a high-speed key, the high-speed movement is performed. In response to the instruction, the pointer is moved at a longer interval than usual or at a shorter interval than usual with respect to the operation amount of the mouse, so that the pointer can be moved at a high speed over a longer distance than usual for a fixed amount of mouse operation. become.

Here, the setting contents of the cursor movement interval for the cursor movement operation will be described with reference to FIG. First, when the cursor keys 12a to 12d are operated, the cursor movement process is repeatedly performed at every key sampling at regular time intervals. The basic movement interval of the cursor corresponding to one key sampling is "high speed". If the key 12e and the "low speed" key 12f are not operated and the standard designation state is (T), the "high speed" key 12

Here, β = α / 2. FIG. 3 is a diagram showing a cursor movement display state accompanying the cursor movement processing in the personal computer. FIG. 3 (A) shows a cursor movement display state in a standard designation state, and FIG. 3 (B) shows a high speed designation state. It is a figure showing the cursor movement display state in a state.

It is determined that there is no operation of the "low speed" key 12f and the fine adjustment level of the slide switch 12g is detected (steps S1 → S2 → S3).
→ S4a).

In this case, the slide switch 12g is set to "medium" and its fine adjustment level is (β =
Since it is detected as ± 0), the cursor K on the display unit 17 is moved and displayed as indicated by an arrow X1 with the width of the cursor K itself as a standard movement interval (T) (step S5a).

As shown in FIG. 3B, with the slide switch 12g of the key input unit 12 set to "medium", the "high speed" key 12e is operated and the cursor key "↓" 12b is pressed. When operated, the "high speed" key 12e
Is determined as the high-speed designation state in which the operation is performed, and the fine adjustment level of the slide switch 12g is detected (step S).
1 → S2 → S4b).

In this case, the slide switch 12g is set to "medium" and its fine adjustment level is (β =
Since it is detected as ± 0), the cursor K on the display unit 17 is moved and displayed as indicated by an arrow X2, for example, as a movement interval (T + α) three times the width of the cursor K (step S5b).

Further, for example, with the slide switch 12g of the key input unit 12 set to "medium", the "low speed" key 12f is operated and the cursor key "↓" 12b
Is operated, it is determined that a low-speed designation state exists in which the "low-speed" key 12f is operated, and the fine adjustment level of the slide switch 12g is detected (steps S1, S2, S3, and S).
4c).

In this case, the slide switch 12g is set to "medium" and its fine adjustment level is (β =
Since it is detected as ± 0), the cursor K on the display unit 17 is moved and displayed, for example, at a movement interval (T-α) of １ ／ of the width of the cursor K (step S5c).

In any of the standard designation state, the high-speed designation state, and the low-speed designation state of the cursor moving speed,
When the slide switch 12g is set closer to “high” or “low” than the “middle” position, the fine adjustment level ± β is detected according to the set position of the slide switch 12g, and the standard designation is made. Is (T ± β), and the cursor movement interval for high-speed designation is (T ± β).
+ Α ± β), and the cursor movement interval when the low speed is specified is (T
−α ± β).

Therefore, according to the cursor movement display on the personal computer having the above configuration, when the cursor keys 12a to 12d are operated while the "high-speed" key 12e is operated, the cursor movement interval for each key sampling becomes the standard interval (T). The cursor is set to a predetermined distance longer (T + α) and the cursor is moved and displayed at a high speed.
While operating the key 12f, the cursor keys 12a to 12d
Is operated, the cursor movement interval for each key sampling is set to a predetermined distance shorter (T-α) than the standard interval (T), and the cursor is moved and displayed at a low speed. The moving speed of the display cursor can be changed.

Further, by operating the slide switch 12g, it is possible to finely adjust the standard, high-speed, and low-speed cursor movement speeds. In the cursor movement process of the above-described embodiment, the interval at which the cursor K moves for each key sampling of the cursor keys 12a to 12d is set to (+) in the case of high-speed designation based on the standard interval (T).
α), when the low speed is designated, the cursor K is changed to (−α) to move and display the cursor K on the display screen at a high speed or a low speed. However, the moving interval of the cursor K is fixed, and the cursor keys 12a to 12d are set. By setting the time interval (timing) for moving the cursor K in response to the operation of the cursor K to be short in the case of high-speed designation and long in the case of low-speed designation, the cursor K can be set to a high or low speed in the same manner as described above. The display may be moved.

Here, the setting contents of the pointer moving distance for the mouse moving operation will be described with reference to FIG. First, when the mouse 13 is moved, the pointer is repeatedly moved every fixed amount of rotation of the ball that rotates with the movement of the mouse 13. The pointer corresponds to one fixed rotation sampling of the mouse ball. The basic one moving distance interval is (T) in the standard designation state in which the "high speed" key 12e and the "low speed" key 12f are not operated, and (T + α) in the high speed designation state in which the "high speed" key 12e is operated. And moves in a shorter distance than the standard when the "low speed" key 12f is operated in the low-speed designation state (T-α).

When the slide switch 12g is set to "high" or "low" in the standard designation state, the pointer movement distance for each of the quantitative rotation samplings is (T + β) or (T-β). When the slide switch 12g is set to “high” or “low” in the high-speed designation state, (T + α + β) or (T + α−β = T + β), and in the low-speed designation state, the slide switch 12g becomes “high”. If it is set to “” or “low”, then (T−α + β = T−β) or (T−α−β).

Here, β = α / 2. 5A and 5B are diagrams showing a pointer movement display state accompanying the pointer movement processing in the personal computer. FIG. 5A shows a pointer movement display state in a standard designation state, and FIG. 5B shows a high-speed designation state. It is a figure showing the pointer movement display state in a state.

FIG. 6 is a diagram showing a pointer movement display state in a low speed designation state accompanying the pointer movement processing in the personal computer. First, as shown in FIG. 5A, the slide switch 12g of the key input unit 12
When the mouse 13 is moved at the distance L1 while the mouse is set to “medium”, it is determined that the “high” key 12 e and the “low” key 12 f are not operated as a standard designated state, and the fine adjustment level of the slide switch 12 g is changed. It is detected (steps A1->A2->A3-> A4a).

In this case, the slide switch 12g is set to "middle" and its fine adjustment level is (β =
± 0), the pointer P on the display unit 17 is
For example, 1/2 of the width of the pointer P is sequentially moved and displayed as a standard moving distance (T) as shown by an arrow X1.
It moves between the distances P1 and P2 (step A5a).

As shown in FIG. 5B, while the slide switch 12g of the key input unit 12 is set to "medium", the "high speed" key 12e is operated, and the mouse 13 is moved to the distance L2 (< When the moving operation is performed in <L1), it is determined that a high-speed designation state exists in which the “high-speed” key 12e is operated, and the fine adjustment level of the slide switch 12g is detected (step A1 → A2 → A4b).

In this case, the slide switch 12g is set to "medium" and its fine adjustment level is (β =
± 0), the pointer P on the display unit 17 is
For example, three times the width of the pointer P is displayed as a moving distance (T + α) as shown by an arrow X1, and the pointer P moves between the same distances P1 and P2 (step A5b).

That is, in this high-speed designated state, the pointer P can be moved over a long distance even if the amount of movement of the mouse 13 is smaller than in the standard designated state. If pointer P
Will be able to move at high speed.

As shown in FIG. 6, the key input unit 12
With the slide switch 12g set to "medium", the "low speed" key 12f is operated and the mouse 13
Is moved by the distance L1, it is determined that a low-speed designation state exists in which the "low-speed" key 12f is operated, and the fine adjustment level of the slide switch 12g is detected (step A1 →
A2 → A3 → A4c).

In this case, the slide switch 12g is set to "medium" and its fine adjustment level is (β =
± 0), the pointer P on the display unit 17 is
For example, 1/4 of the width of the pointer P is defined as the moving distance (T-α).
Are sequentially displayed as indicated by an arrow X2, and the distance P
1 to P3 (<< P1 to P2) (step A
5c).

That is, in this low-speed designated state, even if the moving operation amount of the mouse 13 is the same as in the standard designated state,
Since the pointer P can be moved in a short distance,
When viewed from the same mouse operation state, the pointer P can be moved at a low speed.

In any of the standard, high-speed, and low-speed designated states of the pointer moving speed,
When the slide switch 12g is set closer to “high” or “low” than the “middle” position, the fine adjustment level ± β is detected according to the set position of the slide switch 12g, and the standard designation is made. Is (T ± β), and the pointer movement distance in the case of high-speed designation is (T
+ Α ± β), and the pointer movement distance when the low speed is specified is (T
−α ± β).

Therefore, according to the pointer movement display on the personal computer having the above configuration, when the mouse 13 is moved while operating the "high-speed" key 12e,
The pointer movement distance for each quantitative rotation sampling of the mouse ball is longer than the standard distance (T) by a predetermined distance (T + α)
When the mouse 13 is moved while the "low speed" key 12f is operated, the pointer movement distance for each constant rotation sampling of the mouse ball becomes a predetermined distance from the standard distance (T). Distance short (T
−α) and the pointer is moved at a low speed and displayed, so that the moving speed of the display pointer can be easily changed at an arbitrary timing in the moving operation of the mouse 13.

Further, by operating the slide switch 12g, it is possible to finely adjust the standard, high-speed, and low-speed pointer movement speeds. In the pointer movement process of the embodiment, the distance that the pointer P moves for each constant rotation sampling of the mouse ball is set to a standard distance (T). When designated, it is changed as (-α) to move and display the pointer P on the display screen at high speed or low speed. However, the unit movement distance of the pointer P is fixed, and the fixed rotation sampling value of the mouse ball is Alternatively, the pointer P may be moved at a high speed or a low speed in the same manner as described above by setting a small value when the high speed is specified and a large value when the low speed is specified. The mouse 13 for instructing the movement of the pointer P may be a trackball.
