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.
An operating device for a computer or the like, comprising a support for a human hand provided with at least one button positioned such that it can be operated by the extremity of a finger, said device comprising a bearing surface and a bulbous part, shaped in accordance with the shape of the human hand, arranged thereon, said bulbous part comprising a surface for the palm of the hand for supporting the mid section of the hand (metacarpus)/wrist section (carpus) of the operator, a central surface for supporting the proximal phalanges of the fingers and a distal surface for supporting the medial phalanges and distal phalanges, wherein said distal surface is at an angle (α) of approximately 75° with said bearing surface.
