Mouse With Geodesic Ball

Disclosed is a mouse type analog input device for a computer. Mouse input devices generally have a small spherical tracking ball to convey position information. Disclosed is a geodesic mouse ball.

The geodesic ball has "n" flat sides (like a soccer ball) providing for discrete readings from the mouse rather than continuous. The ball provides a tactile click (detent) so that the user is sure the ball is moving. This tactile feedback is particularly useful for a blind person. If the blind user knew that each click corresponds to one line on the screen, or each click corresponded to 1% of the screen height or width, the blind user would be able to use a mouse with an appropriate program.

The drawing shows a geodesic mouse unit with a top cover 1 with the standard buttons, a base 2, and a geodesic mouse ball 3 (enlarged slightly for diagrammatic purposes). The ball diameter is typically about 1 cm.

Note that two balls could be used, one a geodesic ball for tactile feedback and the other a traditional spherical ball for position sensing. Also note that a user with a physical handicap such as multiple sclerosis may desire a discrete mouse. If the user's hand shakes, a normal mouse is not useable. With the geodesic mouse, there is less wiggling of the mouse controlled cursor-- particularly when attempting to hold the mouse still.

An infrared communications link with the computer unit can be used with the geodesic mouse to eliminate the customary...
