Interactive spatial chirography device

摘要

Disclosed herein is chirography system including a chirography stylus fitted with an ultrasonic transducer tip and a font frame reader employing sensors at reference points of a font coordinate system. The system may be provided with a symbol recognition module adapted to identify symbol path traces of the stylus as the stylus traces the path guided by a cue card for a handwritten symbol. The system may also include an output for affirming successful recognition of a spatial chirography symbol by audibly expressing the identified symbol when the recognition succeeds and/or audibly prompting for another attempt when the recognition procedure fails. The system may employ one of physical and electronic cue cards including symbols adapted to be traced during a learning session.
