Described is a computer-implemented system and method that detects and differentiates scratch-out gestures from other electronic ink, e.g., entered via a pen. The system and method compare boundary-based criteria to differentiate, which eliminates the need to have a specially-shaped scratch-out pattern, instead allowing a wide variety of scratch-out styles to be detected. Criteria includes boundary-based evaluations such as whether the potential scratch-out gesture intersects previously recognized words or characters, whether the scratch-out gesture has a width that is at least a threshold percentage of the width of a word or character bounding box, whether the electronic ink extends beyond the midpoint of the bounding box, and whether at least some portion of the scratch-out gesture is above a baseline of the word or character. Scratch-out gestures entered in freeform input writing areas and boxed input writing areas are supported. |
