SYSTEMS AND METHODS FOR DIGITAL PEN STROKE CORRECTION
First Claim
1. A method for correcting digital pen strokes, the method comprising:
- accessing a stroke collection file comprising data corresponding to a plurality of pen strokes written on a paper form using a digital pen;
determining a first set of coordinates in the stroke collection file corresponding to a removal stroke, the removal stroke written on the paper form so as to identify a corresponding mistake stroke written on the paper form;
determining a second set of coordinates in the stroke collection file corresponding to the mistake stroke; and
removing the first set of coordinates and the second set of coordinates from the stroke collection file.

Abstract
Systems and methods are provided for correcting digital pen strokes written on a paper form using a digital pen. In one embodiment, a stroke collection file includes sets of coordinates corresponding to respective pen strokes written on the paper form including a mistake stroke that a user of the pen desires to correct and a removal stroke written through the mistake stroke using the digital pen. In one embodiment, the removal stroke includes a horizontal zigzag pattern having at least one horizontal extend further to the left and further to the right of the mistake stroke. In one embodiment, coordinates corresponding to the mistake stroke and the removal stroke are deleted from the stroke collection file. The stroke collection file may also include coordinates for a third pen stroke intended to replace the mistake stroke. One embodiment includes rendering an image of the paper form and the third pen stroke.

8. A system for modifying digital pen strokes, the system comprising:
-
a digital pen configured to write pen strokes on a paper form and to store corresponding stroke coordinates in a stroke collection file; and a processor configured to; determine a first set of coordinates in the stroke collection file corresponding to a first pen stroke, the first pen stroke written on the paper form so as to identify a corresponding second pen stroke written on the paper form, the second pen stroke being written before the first pen stroke; determine a second set of coordinates in the stroke collection file corresponding to the second pen stroke; and remove the first set of coordinates and the second set of coordinates from the stroke collection file. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)
