<p>An approach to keyboard development is described which integrates ergonomic modification with the psychological resistance to changing existing, familiar keyboard designs. Accordingly, ways are described to more properly fit the natural positions of the fingertips in the typing position with the geometric relationships between keys. In addition, a correspondence is drawn between the relative positions of the base of the fingers (28) where they meet the hand, the relationship between the base of the fingers (28) and the wrist (38), and the natural orientation of the fingertips of a typist. This is supported by a theory concerning the way the human brain may track the positions of the fingers and hands. As well, the creation of logical groups are detailed which allow more ergonomic adjustment of the keys, yet preserve the existing geometry of an original keyboard. In particular, these ergonomic modifications are applied to the standard geometry of the 'Qwerty' or 'Dvorak' keyboard, though application to other types of keyboards is also described.</p> |
