Abstract
An ergonomic mouse is described. A computer mouse may include a position tracking engine and a housing to encapsulate the position tracking engine. The housing may have a bottom portion with a substantially flat surface and an aperture for the position tracking engine. The housing may also have a top portion having a convex portion with a convex curved surface and a first concave portion with a first concave curved surface to receive a human thumb. The first concave portion may have an orientation relative to the bottom portion to cause a substantially neutral wrist deviation when a user grips the top portion.
Claims20
A computer mouse, comprising:
- a position tracking engine;
- and
- a housing to encapsulate said position tracking engine, said housing having a bottom portion with a substantially flat surface and an aperture for said position tracking engine, and a top portion having a convex portion with a convex curved surface and a first concave portion with a first concave curved surface to receive a human thumb, said first concave portion having a substantially horizontal orientation relative to said bottom portion to cause a substantially neutral wrist deviation when a user grips said top portion.
An input device, comprising:
- a position tracking engine;
- and
- a housing to surround said position tracking engine, said housing having a top portion and a bottom portion, said bottom portion having an aperture for said position tracking engine, said top portion having a convex portion with a convex curved surface to fit an average human hand in a relaxed state, and a thumb scoop formed to receive a human thumb, said thumb scoop positioned to cause a substantially neutral wrist deviation when a user grips said housing with said human hand.
A human interface device, comprising:
- a position tracking engine;
- and
- a housing to house said position tracking engine, said housing having a top portion and a bottom portion, said bottom portion having a substantially flat surface and an aperture for said position tracking engine, said top portion having a convex portion with a convex curved surface to fit a human hand, and a concave portion with a concave curved surface to receive a human thumb, said concave portion having a substantially horizontal orientation relative to said bottom portion to reduce wrist deviation to less than eight degrees deviation when a user grips said top portion with said human hand.
