ABSTRACT:
An ambidextrous upright computer mouse includes a relatively upright finger engaging side on one side, and a thumb engaging side on an opposite side. Two sets of buttons are positioned at opposite ends of the finger engaging side. The mouse is symmetrical about a vertical transverse medial plane. When the finger engaging side is on the right side, the mouse can be grasped by a right hand. When the mouse is rotated so that the finger engaging side is on the left side, it can be grasped by the left hand. There is always a set of buttons at the forward end of the mouse, regardless of its orientation. Only one set of buttons is enabled at any time. The sets of buttons are alternately enabled and disabled by moving a selector switch. Ambidexterity is provided without compromising feel and comfort for either hand.
