Force-feedback input device
First Claim
1. A force-feedback input device comprising:
- display means for displaying a cursor and a plurality of buttons;
input means comprising an operating portion, a detecting portion for detecting an amount of movement of the operating portion, and an actuator for providing a required external force to the operating portion; and
control means for controlling the display of the cursor based on an operational amount signal from the detecting portion and for controlling driving of the actuator so as to provide an attractive force to the operating portion based on a positional relationship between the cursor and the buttons;
wherein the control means controls driving of the actuator based on a positional relationship between the cursor and a borderline between a first attractive area and a second attractive area appearing in vicinities of adjacent first and second buttons.

Abstract
In a force-feedback input device, when the cursor moves on a line parallel to a line between a center of a first button and a center of a second button, an area is determined between a first position, which corresponds to the center of the first button, and a second position, which corresponds to the center of the second button, such that the area extends a distance W on both sides of a mid-point between the first and second positions. In this area, the first and second external-force generation portions are controlled so that a scalar value |F| of an attractive force exerted on an operating portion is decreased according to the equation |F|=d/W·|F| as the cursor moves closer to the mid-point, where d is a distance between the cursor and the mid-point.
