Abstract: An ergonomic computer mouse has support surfaces that are adjustable in two directions. The mouse includes a pivot mechanism that couples an upper and lower portion of the mouse housing together. The pivot mechanism may allow a user to adjust the upper and lower housing portions in pitch and roll directions with respect to one another.

Abstract: An ergonomic computer mouse has support surfaces that are adjustable in two directions and that distribute the mechanical pressure points afforded by the mouse to the metacarpal region. The mouse has a housing with a proximal metacarpal support and a distal metacarpal support on its upper surface that are separated by a midsection. In use, the proximal end of the user's metacarpal hand region rests on the proximal metacarpal support, the distal end of the user's metacarpal hand region rests on the distal metacarpal support, and the remainder of the user's metacarpal hand region between their proximal and distal ends span the midsection. The mouse may further include a pivot mechanism that couples an upper and lower portion of the mouse housing together. The pivot mechanism may allow a user to adjust the upper and lower housing portions in pitch and roll directions with respect to one another.
