Abstract:
1. A character recognition method, comprising: using a processor to perform the following method; queuing continuous path data made by traversing edges and diagonals and into corners within a confining geometric shape constraining an input device to less than the input device's total area; searching the queued continuous path data to generate a sequence of corner hits, where a corner hit corresponds to a corner defined by said geometric shape; identifying a character based on said sequence of corner hits independently of the remainder of the continuous path data; wherein each of said sequences of corner hits defines a single stroke, and wherein each single stroke is representative of one of a letter, number, punctuation or mode; and identifying a letter character as being upper case when said stroke representative of said character ends in a common predetermined corner and lower case when said stroke does not end in said common predetermined corner.
