Abstract
The invention concerns a device for the one-handed input of coordinates of multi-axis coordinate systems and alphanumeric characters and control commands, the device being operable with one hand. The forearm does not participate in the movements and rests on a support. The device comprises a plurality of elongated keys having sensor surfaces which, when depressed, detect and evaluate the position of a fingertip as a coordinate. The device comprises a housing which detects and evaluates the ulnar pivot movement of the hand as a horizontal coordinate and the pronation of the hand and a translation in the direction of the arm as control signals. The device combines the input functions of a mouse and a keyboard.
