An improvement for computer mouse device includes a housing which has a bottom surface, a top surface, a first side surface, a second side surface, at least one button and a tracking device. A fillister shape is formed on the top surface and capable of accommodating at least one human figure, so that user's index finger may be rested on the fillister shape to move the mouse around for controlling curser motion and has the index finger tip drop vertically downward to press the button for selecting and excuting computer commands. The mouse is thus much more ergonomically designed and shaped to reduce muscle and nerve stress from undue jesture for fingers, palm and wrist. User may operate the mouse for a long period of time of reduced traditional stress and fatiuge or other harmful effect.
