Annotation detection and anchoring on ink notes

摘要

Systems and methods for detecting annotation digital ink strokes and further associating annotation digital ink strokes with word digital ink strokes are presented. Ink strokes are captured on a writing surface and then classified as words or annotations. Annotations are then anchored to corresponding words. When words are relocated or edited on the writing surface, the anchored annotations are also relocated and may even be reshaped according to the changes in the anchored words.

主权项

1. A computer-implemented method comprising:
receiving digital ink strokes; classifying at least some of the digital ink strokes as word digital ink strokes; classifying at least some of the digital ink strokes as annotation digital ink strokes; anchoring the annotation digital ink strokes to the word digital ink strokes to represent annotated words; and breaking the annotation digital ink strokes into two separate annotations responsive to receiving a command to delete a portion of the annotated words that are between other portions of the annotated words, each of the two separate annotations maintaining an associated previously anchored portion of the annotation digital ink strokes associated with annotated words that were not deleted.
