ABSTRACT:
An improved peripheral device for a computer includes a miniature motion-sensing mechanism which is placed in a pen-shaped body to allow computer input to be accomplished by a user in the familiar form of a pen or pencil. The mechanism include a rolling ball supported at six points by support shafts whose movement in response to ball motion is converted into signals indicative of the direction and magnitude of the movement of the device.
