THREE-COORDINATE GRAPHICAL INFORMATION HANDLER BUILT AROUND SINGLE-COORDINATE TRANSDUCERS Russian patent published in 2001 - IPC

FIELD: computer peripheral devices; data input devices. SUBSTANCE: handler has at least three single-coordinate displacement transducers each recording linear displacement relative to reference surface. Rotational and translational components of handler movement within its coordinate system or within coordinate system related to reference surface are computed by machine program or by handler-servicing controller using readings of single-coordinate displacement transducers. Handler provides for introducing additional angular coordinate for turning relative to reference surface. EFFECT: simplified design of handler. 2 cl, 3 dwg
