ABSTRACT:
A keyboard which integrates ergonomic modifications, but which overcomes the psychological resistance to changing existing, familiar designs. The positions of the keys are determined with reference to the natural positions of the fingertips in the typing position and the geometric relationships between keys. The keyboard layout is based upon consideration of the relative positions of the bases of the fingers and where they meet the hand, the relationship between the bases of the fingers and the wrist, and the natural orientation of the fingertips. The creation of groups of keys allows ergonomic adjustment of the keys, while preserving much of the geometry of a standard keyboard. In particular, these ergonomic modifications are applied to the standard geometry of the "Qwerty" or "Dvorak" keyboard.
