ABSTRACT:
A system is provided for recording writing performed on a surface. The system includes a stylus having a housing and a writing element; two or more detectors which may be permanently or removably affixed to a writing surface; and a processing unit. The stylus and detectors are used in combination to detect the position of the stylus on the writing surface relative to the detectors based on a time of flight of a ranging medium propagated between the stylus and detectors. The relative position of the stylus is determined at multiple times during which the stylus is being employed in order to record the writing on the surface.
