Abstract:
A method for selecting a keyword in a handwriting recording device having an electronic inking stylus and a digitizing tablet associated therewith, wherein the device records stroke data representing handwritten strokes concurrently produced on a writing medium placed over the digitizing tablet using the electronic inking stylus, the method comprising the steps of:invoking a keyword selection mode, wherein the keyword selection mode allows a user to designate one or more recorded strokes as a reference keyword;accepting as input, handwritten bounding strokes;defining a bounding region as the area contained within the handwritten bounding strokes; anddetermining keyword membership of a recorded stroke based on a relation between the recorded stroke and the defined bounding region,wherein the step of determining keyword membership includes the steps of:determining each stroke which is entirely contained and partially contained in the bounding region;for each partially contained stroke, calculating a percentage of the stroke contained within the bounding region;comparing each calculated percentage to a prespecified threshold; andselecting as keyword members the strokes that are determined to be entirely contained within the bounding region and the partially contained strokes having a calculated percentage which exceeds the prespecified threshold.
