ABSTRACT:
An optical data entry and display system for decoding handwritten symbols into a data processing code is disclosed. The system comprises a television monitor for displaying decoded and otherwise derived symbols as well as for displaying a sequence of light spots on which a symbol may be traced by means of a light pen. The positions of the light spots comprising the trace are used in a comparison with a set of stored values defining the predetermined symbols to decode the trace.
