A system and method for tracking a moving object very accurately at short ranges in general, and a handwriting input device such as a pen in particular. The method is based on measuring times of arrival of ultrashort RF pulses transmitted by the pen to an array of receivers. Dealing with the ultrashort events is done by 'strobing' the pen position. To achieve the necessary resolution, on the order of 0.25 mm, the times of arrival of the pulses are determined by sampling the pulses digitally and fitting appropriate mathematical functions to the samples pulses. The time jitter is averages over many sweeps, and a dedicated receiver is used for synchronization.

Method and system for digitizing handwriting

Handwriting recognition apparatus including handwriting input apparatus employing at least two different sensing techniques to sense handwriting and symbol identification apparatus receiving an output of the handwriting input apparatus for providing an output indication of symbols represented by the handwriting.
