Abstract
Abstract An ergonomic computer mouse includes an upright, primary finger-supporting surface for supporting all of the fingers of an upright hand in straight positions and in an upright stack. It also includes an opposite thumb-supporting surface for supporting the thumb. A hand holding the ergonomic computer mouse will be in a naturally upright and relaxed position, without requiring twisting of the hand, wrist, or forearm. As a result, fatigue, discomfort, and pain are minimized or eliminated even after a long period of continuous use.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
174 words
An ergonomic computer mouse for translation over a horizontal stationary surface, comprising: a generally horizontal bottom surface for stably and translatably positioning said mouse over said stationary surface; a housing attached on top of said bottom surface, said housing having a forward end, a rear end, and opposite sides extending continuously between said forward end and said rear end; one of said sides being a generally vertical finger-supporting surface for supporting the fingers of a generally upright hand in a generally vertical stack, so that the little finger is at the bottom thereof and the index finger is at the top thereof, said finger-supporting surface being generally elongated in a horizontal direction for supporting the fingers in generally straight positions; and another one of said sides being a thumb-supporting surface for supporting the thumb of said hand, so that said mouse is securely gripped between the thumb and the fingers, and is easily maneuvered by flexing the straight fingers and the thumb, and the hand is in a relaxed, untwisted, and naturally upright position.
Claim 2
Dependent Claim
