ASSOCIATING STROKES WITH CONTENT

摘要

A method and apparatus for associating strokes with content are described. In one embodiment, an apparatus comprises: a memory to store contexts for a plurality of strokes, wherein each context represents an association between at least one stroke and a portion of image data previously displayed; and a matching module coupled to the memory to: receive an indication of a new stroke to be associated a first image and a first context, determine if the portion the first context is the same as, overlaps or is independent of the contexts stored in the memory, and update the memory to include the new stroke by adding the new stroke to one of the contexts stored in the memory or storing the new stroke with the first context independent of the contexts already stored in the memory.

1. An apparatus for use with a display surface that displays content and allows strokes to be written over the content on the display surface, the apparatus comprising:
a memory to store contexts for a plurality of strokes, wherein each context represents an association between at least one stroke and a portion of image data previously displayed; a matching module coupled to the memory to:
receive an indication of a new stroke to be associated a first image and a first context,determine if the portion the first context is the same as, overlaps or is independent of the contexts stored in the memory, andupdate the memory to include the new stroke by adding the new stroke to one of the contexts stored in the memory or storing the new stroke with the first context independent of the contexts already stored in the memory.
