EVALUATION OF HAND PRINTED CHARACTER RECOGNITION TECHNIQUES.
Abstract
Four experiments investigated the effects of logic, constraints, and feedback on the entry of data into a system by hand printing. The results of these experiments showed that automatic hand print recognition systems are well within the current state-of-the-art; that well devised constraints are readily learned, used, and retained, but that great care must be taken to make them as natural as possible; that visual feedback has only a small effect on speed and accuracy of initial entries but is vital to immediate editing and correction, and that adaptive and constrained systems appear to differ more in matters of convenience than in accuracy and economy. A system based on feature-analysis logic, with relatively restrictive but natural constraints, utilizing a data entry tablet and a CRT scope feedback is recommended. (Author)
