ABSTRACT:
An ergometrically improved keyboard data input device particularly suited for computers includes a housing adapted to underlie the palm of the hand of an operator in a relaxed, natural, concave position; so that the fingertips of each finger extend substantially vertically downward through an aperture in the top of the housing. Data input keys are mounted on a data input key support member located inside the housing, beneath the aperture. The keys are arranged in groups of data input keys in three dimensional patterns at each of the fingertip positions of the hand of the operator. The device includes a provision for raising and lowering the key support member within the housing, relative to the aperture. Actuators also independently move the opposite ends of the key support member back and forth within the housing, relative to the aperture, to adjust the locations of the groups of keys relative to the portion underlying the palm of the hand of a user to compensate for hands of different sizes.
