An ergonomic keyboard input device for use with a coupled electronic system, such as a computer. The device includes a keyboard which is organized with an array of actuation keys that are disposed generally to complement the splayed underside architecture of a user's hand. A two-handed implementation is disclosed wherein each array includes, for each finger in a hand, an associable cluster of input keys which are placed in such a manner that they enable key actuation via only slight, gestural, relatively closing motion of a portion of a confronting finger, and for the thumb in each hand, an associable cluster of keys disposed generally over three mutually intersecting, and somewhat orthogonal, surfaces that enable thumb/key actuation via mixed lateral, and slight endo, translation of the thumb generally within a cone of motion whose apex resides adjacent the base of the thumb.
