Method and apparatus for reducing repetitive motion injuries in a computer user

摘要

A pointing device is provided for use with a computer, including a tracking device adapted to generate a signal for use by a processor in moving a pointer on screen, and a selecting device adapted generate a selection signal for use by the processor to determine operations to execute. The tracking device and the selecting device are respectively incorporated into at least two distinct apparatuses that are separately operable by different and multiple user body parts. In exemplary embodiments of the invention, the improved pointing device may be operated at least in part by, for example, several of a user's fingers, by a foot, or by a user's eyes. The pointing device thus distributes conventional mouse functions in a way that allows them to be executed by multiple body parts, thereby reducing repeated stress to any single user appendage.
