Abstract

A system and method are provided for editing handwritten data using a pen enabled computing device having a writing surface and a writing stylus selectively communicable with the writing surface. The method includes detecting the position and movement of the writing stylus with respect to the writing surface to form a handwritten input, and defining a bounding box encompassing at least a portion of each stroke of the handwritten input. In addition, the method includes storing the handwritten input and the bounding box encompassing at least a portion of each stroke thereof. The handwritten input may be edited to add textual data to the handwritten input, insert textual data between strokes encompassed by adjacent bounding boxes, delete at least one stroke encompassed by a bounding box, and/or replace at least one stroke encompassed by a bounding box with alternate textual data.

Claims

1. A method for editing handwritten data using a pen enabled computing device having a writing surface and a writing stylus selectively communicable with the writing surface, said method comprising:

detecting the position and movement of the writing stylus with respect to the writing surface to form a handwritten input;

defining a bounding box encompassing at least a portion of each stroke of the handwritten input;

storing the handwritten input and the bounding box encompassing at least a portion of each stroke thereof; and

editing the handwritten input to at least one of add textual data to the handwritten input, insert textual data between strokes encompassed by adjacent bounding boxes, delete at least one stroke encompassed by a bounding box, and replace at least one stroke encompassed by a bounding box with alternate textual data.

2. A method according to claim 1 wherein detecting the position and movement of the writing stylus comprises sampling the motion of the writing stylus with respect to the writing surface so as to form a coordinate representation of each stroke of the handwritten input.

3. A method according to claim 2 wherein editing the handwritten input comprises receiving an indication from a user of the handwritten input to be edited and receiving textual input from a keyboard to form the textual data with which the handwritten input is edited.

4. A method according to claim 3 wherein editing further comprises altering the coordinate representation of at least some strokes of the handwritten input in order to alter spacing of at least one stroke encompassed by a bounding box so as to at least one of insert the textual input between strokes encompassed by adjacent bounding boxes and replace a stroke encompassed by a bounding box containing handwritten input with the textual input.

5. A system for editing handwritten data comprising:

a pen enabled computing device having a memory element, a writing surface, and a writing stylus selectively communicable with the writing surface; and

a computer program product executing within said pen enabled computing device and cooperating therewith for;

detecting the position and movement of the writing stylus with respect to the writing surface to form a handwritten input;

defining a bounding box encompassing at least a portion of each stroke of the handwritten input;

storing the handwritten input and the bounding box encompassing at least a portion of each stroke thereof; and

editing the handwritten input to at least one of add textual data to the handwritten input, insert data between strokes encompassed by adjacent bounding boxes, delete at least one stroke encompassed by a bounding box, and replace at least one stroke encompassed by a bounding box with alternate textual data.

6. A system according to claim 5 wherein said computer program product samples the motion of the writing stylus with respect to the writing surface so as to form a coordinate representation of each stroke of the handwritten input.

7. A system according to claim 6 wherein said pen enabled computing device and said computer program product cooperate for receiving an indication from a user of the handwritten input to be edited and also for receiving textual input from a keyboard to form the data with which the handwritten input is edited.

8. A system according to claim 7 wherein said computer program product edits the handwritten input by altering the coordinate representation of at least some strokes of the handwritten input in order to alter spacing of at least one stroke encompassed by a bounding box so as to at least one of insert the textual input between strokes encompassed by adjacent bounding boxes and replace a stroke encompassed by a bounding box containing handwritten input with the textual input.
