ABSTRACT:
There is provided an apparatus for supporting one's limbs, preferably one's arms, while at a work station which may be a computer keyboard. The apparatus includes a pair of rollers mounted on an axle. The rollers are especially adapted to support the forearms and will rotate as well as move in axial directions. The rollers are maintained at a predetermined distance from the work station and are adjustable in the horizontal and vertical directions. A sensor is mounted on the axle and is periodically contacted by the rollers to provide information to the computer. By various methods of sensing roller movement, the rollers may generate data for computer or machine control as well as support the arms in various tasks.
