ABSTRACT:
This invention provides novel keyboards comprising keys disposed such that they minimize the distance a finger typically must travel to effect a keystroke and the force that is applied to effect a keystroke. Accordingly the keyboards require less arm and finger movement to and thereby reduce the likelihood of an operator developing a repetitive stress injury (RSI). In one embodiment the keyboards comprise a plurality of keys disposed such that the alphanumeric keys form a continuous key array defining a key array surface having at least two concave regions wherein a plurality of keys present irregular and/or non-rectilinear striking faces.
