Abstract
A drawing assistance system enhances a sketch drawn by a user in an electrical document on a computer system by collecting stroke data from one or more strokes of a sketch as a user draws the sketch. The stroke data includes time-based information and features of each stroke. The strokes are handled based on the time-based information, and analysed based on the strokes handled based on the time-based information. The sketch is enhanced based on results of the analysis.
