ABSTRACT:
An apparatus for collecting information directly at a point on a surface comprises the combination of a stylus with means for sensing force along at least one axis in a surface at a point on the surface and a position sensing platen or pad with means for sensing a true position along at least one axis on the surface at the point in question. Collected information is processed to obtain figures of merit. Features extraction or rubbery correlation in five dimensions may be employed to obtain suitable figures of merit for objective evaluation.
