Abstract
A method of producing an adaptive partial ink layer for a pen based computing device is described. The adaptive partial ink layer is used to form an ink trail, which follows the input pen as it moves in contact with a touch screen. This allows the user to view the input while it is being made, which allows the input to be improved through the visual observation. A three-cell block is formed to permit single character input from the pen and then the block is extended in the direction of a cursive input to accommodate a word or phrase. Whereas, a common direction for the cursive input is from left to right, any direction emanating from the three cell block can be used if the interpreter of the pen passed computing device is set up to allow such an input.
