Abstract
An apparatus and method for inputting a hand-generated character into a computer. A user draws a character using a drawing apparatus. As the user draws, movement of the apparatus and characteristics of such movement are detected. The apparatus generates a code for the character being drawn as a time dependent sequence of signals by comparing the characteristics of the movement as the character is drawn with a predetermined set of characteristics, with each signal corresponding to the predetermined characteristic closest to the actual characteristic detected at each successive step of movement. The apparatus provides visual feedback to the user by displaying in sequence each component of a character that is being drawn positionally independently of the movement of the drawing apparatus.
