The present invention is an improved computer mouse for inputting cursor commands into a computer of the type having a flat base with a tracking means for use on a flat work surface and switches operable with the fingers of the user. The improved computer mouse comprises a housing having a flat base, a vertical rear wall at a right angle to said flat base, a top and front surface disposed between the front edge of the base and the upper edge of the rear wall. The base having a front to rear dimension less than the height of the rear wall, so that the mouse is readily tiltable rearwardly. Also provided is a means for disabling the mouse when so tilted. The top and front surface being so disposed and elevated such that the user's hand is positioned above the work surface: (i) so that his/her fingers drape over the mouse touching the work surface or slightly thereabove, and (ii) so that the user's wrist is straight or substantially straight whereby repetitive or prolonged use of the mouse will lessen the likelihood of developing carpal tunnel syndrome, tendonitis or a related condition.
