OPERATING DEVICE FOR A COMPUTER

摘要

Operating device such as a mouse for operating a computer or the like. This device consists of a flat bearing surface on which a bulbous part has been arranged. This bulbous part consists of three (curved) surfaces, a surface for the palm of the hand for supporting the metacarpus/carpus, a central surface for supporting the proximal phalanges of the fingers and a distal surface for supporting the medial and distal phalanges. According to the present invention, the distal surface is made at an angle of approximately 75° with respect to the bearing surface. As a result of this angle there is optimum support for the fingers over the entire contour and it is possible to prevent RSI-like phenomena by preventing lifting movements of the fingers, which in the long term give rise to RSI-like phenomena.
