Characters printed by hand on an economical input device are recognized immediately after their completion by a computer software. A total of 86 characters, viz. Japanese Katakana characters, 10 numerals, and some symbols are recognized by the scheme. A character pattern is analyzed and approximated by pieces of lines called segment. The data on segments are stored in a data structure, a bi-directionally linked linear list. Features are extracted from the list and by the existence of specific features,the input pattern is identified by a decision tree. A demonstration was carried out from a remote terminal (about 10 kilometers away from the computer) which was connected to the computer via commercial telephone lines. There was no serious problem of noises caused by a long distance transmission. This real time character recognition scheme was also applied to a man-machine communication system called CRIARS which recognizes hand-printed characters and responds in synthesized speech.
