Abstract
To relax the graphical constraints on the precision of the handwriting that is required for accurate computerized interpretation of handwritten text, the text that is to be interpreted is written in accordance with this invention using symbols that are exceptionally well separated from each other graphically. These symbols preferably define an orthographic alphabet to reduce the time and effort that is required to learn to write text with them at an acceptably high rate. Furthermore, to accommodate "eyes-free" writing of text and the writing of text in spatially constrained text entry fields, the symbols advantageously are defined by unistrokes (as used herein, a "unistroke" is a single, unbroken stroke).
