Abstract
Digitizing apparatus comprises an array of Hall effect elements. The array includes conditioning circuitry and scanning circuitry for sensing the conditions of all Hall effect elements and determining which elements have been actuated by a user manipulated magnetic actuator. The apparatus inputs digital signals into a computer, the signals indicating relative positions of actuated Hall effect elements.
