ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to an operating apparatus for moving an object to be controlled in accordance with an inputting operation applied to an input member by the operator.
The present application is based on Japanese Patent Application No. Hei. 10-66400, which is incorporated herein by reference.
2. Description of the Related Art
FIG. 11
shows a note-type personal computer, and by moving a stick-like pointer P, mounted on a keyboard, right, left, back and forth, a cursor C on a screen can be moved right, left, back and forth. As shown in
FIG. 12
, four strain gauges SG for detecting the direction and magnitude of an operating load, applied to the pointer P, are mounted on a proximal portion of the pointer P, and are circumferentially spaced 90° from one another, and the cursor C is moved in the direction of the operating load, detected by the strain gauges SG, at a speed proportional to the magnitude of this operating load.
If a control gain is increased in order to rapidly move the cursor C to a target position on the screen, the cursor C often overshoots the target position to thereby cause the hunting unless the pointer P is carefully operated. If the control gain is decreased in order to avoid this, there is encountered a problem that the speed of movement of the cursor C is lowered, so that it takes a longer time for the cursor to reach the target position.
SUMMARY OF THE INVENTION
With the above problem in view, it is an object of this invention to provide an operating apparatus for moving an object to be controlled in accordance with an inputting operation applied to an input member by the operator, in which the object to be controlled is rapidly moved to a target position by operating an input means, and is stopped there.
According to the invention, there is provided an operating apparatus for moving an object to be controlled in accordance with an inputting operation applied to an input member by the operator, wherein, while the inputting operation by the operator continues, the object to be controlled is stopped for a predetermined period t
2
at the time when a predetermined time period t
1
elapses after the start of the inputting operation.
In this construction, even if the operator does not stop the inputting operation, the object to be controlled is once stopped automatically after this object moves for the predetermined time period t
1
, and therefore even if a control gain is set to a large value so as to rapidly move the object to be controlled, or even if the operator effects the inputting operation roughly, the object to be controlled can be easily moved toward the target position, and can be properly stopped there without overshooting.
In the above, a speed of movement of the object to be controlled increases in accordance with the increase of an amount of the inputting operation by the operator.
In this construction, the speed of movement of the object to be controlled increases and decreases in accordance with the increase and decrease of the amount of the inputting operation by the operator, and therefore if the inputting operation amount is increased so as to much move the object to be controlled, the object to be controlled is moved a large distance at high speed, and then is once stopped, and in contrast, if the inputting operation amount is decreased so as to move the object to be controlled a little, the object to be controlled is moved a small distance at low speed, and then is once stopped. Thus, the intention of the operator can be reflected in the movement of the object to be controlled.
The movement speed of the object to be controlled does not always need to be proportional to the amount of the inputting operation by the operator, but may need only to increase in accordance with the increase of the amount of the inputting operation by the operator.
Further, in the above invention, if the inputting operation by the operator is still continued upon lapse of the predetermined period t
2
, the movement of the object to be controlled is resumed.
In this construction, if the operator wishes to further move the once-stopped object to be controlled, the movement of the object to be controlled can be resumed merely by continuing or maintaining the so far-effected inputting operation without the need for starting a fresh inputting operation, and therefore the operating burden on the operator will not increase.
Still further, the predetermined period t
2
decreases in accordance with the increase of the amount of the inputting operation by the operator.
In this construction, if the operator wishes to further move the once-stopped object to be controlled, the time period of stop of the object to be controlled can be reduced by increasing the inputting operation amount, and therefore if the operator wishes to move the object to be controlled rapidly, the time period of stop can be reduced, thereby suppressing the operator's feeling of difference to a minimum. In the case where the object to be controlled is a steering member of a moving body, the object to be controlled can be moved rapidly in accordance with the operator's emergency.
The predetermined period t
2
does not always need to be inversely proportional to the amount of the inputting operation by the operator, but may need only to decrease in accordance with the increase of the amount of the inputting operation by the operator.
Still further, the object to be controlled is a steering member of a moving body, and the predetermined time period t
1
decreases in accordance with the increase of a speed of movement of the moving body.
In this construction, the time period of movement of the steering member of the moving body decreases in accordance with the increase of the speed of movement of the moving body, and therefore the movement distance of the steering member is decreased when the moving body moves at high speed, thereby preventing the path of movement of the moving body from becoming unstable.
Features and advantages of the invention will be evident from the following detailed description of the preferred embodiments described in conjunction with the attached drawings.
