Abstract: Force resolving system and method which are particularly suitable for use in the analysis of handwriting and the verification of signatures. A platen is coupled to a plurality of force transducers in such manner that only forces acting along mutually perpendicular axes are applied to the transducers. In one disclosed embodiment, each of the transducers has a film of piezoelectric material and a pressure plate which bears against the film, and forces are applied to the transducers by balls in rolling engagement with the pressure plates. In another disclosed embodiment, the forces are applied to the transducers by flexure elements connected between the platen and the pressure plates. The balls and flexure elements transfer forces acting in a directions perpendicular to the film and permit relative movement of the platen and the transducers in directions parallel to the film.
