An ergonomic keyboard as shown in FIG. 3 A for use with a stationary palm wherein the keys ( 15 ) of the keyboard are actuated only by motion of the joints in the digits. The keyboard may have a thumb region ( 20 ), a palm rest region ( 8 ) and a hypothenar rest region which are discrete parts and are adjustable relative to one another along a longitudinal axis. Some keys may be actuated by the back surface of the digits. The keyboard may be on an upper portion ( 2 ) which is mounted on a base ( 1 ) such that three dimensional rotational adjustment is possible between the upper portion and base. The position of the keyboard relative to a user may be adjusted. The spacing of the keys on the keyboard may be spaced at different intervals and have different forces for actuation.
