Abstract
A keyboard unit with several ergonomically arranged keys, the keyboard unit consisting partly of a knob having an upper surface suitably shaped for the support of the inside hollow palm of the guiding hand, the knob having a frontal surface with a row of keys ergonomically operational by the fingers of the hand, and on an inside surface a minimum of one key to be actuated by the thumb, the knob being mobile in two coordinate directions, that is, in the longitudinal direction of the arm and perpendicular to it, covering an entire area of input positions, giving the final choice to the finger selection of the proper key for the intended input.
