Pointing device
First Claim
1. A pointing device comprising:
- a flat cursor-moving switch for moving a cursor;
a cloth sheet which is attached to the rear of the cursor-moving switch and spread on a place where a lying operator'"'"'s hand or finger is laid on to install the cursor-moving switch to be operated on a rugged, irregular or non flat surface;
a band-shaped clicking switch provided at the band with an electrode for making a right click and a left click and provided at overlapping portion of the band with a detachable fastening member adjustable in size according to the size of wearing portion;
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 to a personal computer; and
cables and connectors with which the controller, the switches and the personal computer are connected to each other, wherein cursor-moving switch has a structure in which an operation button is automatically returned to the center position when the cursor-moving switch is not in use.

Abstract
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.
