Means for inputting characters or commands into a computer
First Claim
1. Means for inputting a hand generated character into a digital device comprising means for drawing a character, means for detecting characteristics of movements in drawing a character to produce a code for the character as a time dependent sequence of signals, by comparing each characteristic as the character is drawn with a predetermined set of characteristics, each signal corresponding to the predetermined characteristic closest to the actual characteristic detected at each successive step of movement, and visual feedback means, wherein a component of a character is displayed with each successive signal in the sequence for the character being hand generated positionally independently of the drawing means.

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.
