Abstract

See full text

Obtaining data for signature recognition or data entry are relatively expensive because the apparatus used at each entry point is fairly complex. The present invention employs a relatively inexpensive pen which may be a ball pen with a transparent ball, an ink reservoir, a light sensitive device and an analyzing circuit. Either the circuit or apparatus coupled to the pen is arranged to analyze, on a temporal basis, light received by the light sensitive device which has been modulated as the pen is used to write on closely lined paper. Alternatively, the pen may contain storage and transmit data for external analysis. The analysis can be used, for example, in signature verification or data entry. Other forms of inexpensive devices for obtaining data using pens writing on lined paper are described.
