Abstract : The document describes a program for recognizing hand-printed information in real time, which provides on-line computer users with a means of inputting two-dimensional information as simply as writing with pen and paper. The program operates under the Time-Sharing System on the Q-32 computer at SDC, and uses a RAND Tablet for input and a CRT display (rear-projected on the tablet for output). Each user of the program builds a unique character dictionary, based on samples of his own input characters. For each user, the program currently recognizes about 100 different characters, which are chosen from a larger alphabet by the individual user. The document describes how the recognition program interfaces with the Time-Sharing System; what functions the program performs in recognizing hand-drawn input; and how the character dictionary is constructed and tested. The report concludes by suggesting that the character recognizer will realize its greatest potential by being applied to problems that require free-form (rather than linear keyboard) input. (Author)
