Abstract

A keyboard for a computer is used with the hands of a user disposed substantially in a prehensile position with the thumb opposed to the fingers in a grasping position. The keyboard includes a first slanting keyboard surface for locating keys to be activated by a user's left hand adjacent and sloping downwardly away from a second slanting keyboard surface for locating keys to be activated by a user's right hand. The first and second keyboard surfaces are joined at a peaked central edge forming a V-shape which slopes downwardly toward a user and laterally away from the user. Twelve numbered function keys are positioned in a circular array toward an outward end of the first keyboard surface. A keypad for locating numeric keys is positioned toward an outward end of the second keyboard surface. A cursor control unit on a front surface of the keyboard, below the space bar, is used for controlling the movement of a cursor and is operated by the thumb of the user in a direction transverse to the direction of operation of the keys. The space bar may also be operated in the transverse direction or at a selected angle. Ulnar abducted deviation and hand-pronation are reduced by using the keyboard, thus reducing the incidence of carpal tunnel syndrome.
