POINTING DEVICE AND CURSOR-MOVING SWITCH

摘要

A pointing device which can be operated by a disabled person with a declined muscular strength, even when the person lies in a bed, to move a cursor and make a click separately not only by one hand but also by a body portion having a motor function with a light touch without any complex movement and large motion, and which does not need any operation area. The device comprises a flat cursor-moving switch for moving a cursor, a ring-shaped clicking switch for making a right click and a left click, a cloth sheet which is detachably attached to the rear of the cursor-moving switch if necessary and spread on the place where the cursor-moving switch is operated to enable the installation of the cursor-moving switch on a place other than a flat surface, a controller which measures the direction and distance of the movement of the cursor made by the operation of the cursor-moving switch, detects the click made by the operation of the clicking switch, and transmits the data thereon, and cables and connectors with which the controller, the switches and a personal computer are connected to each other. The cursor-moving switch has a structure in which the operation button is returned to the center automatically when not used.
