Identification of Single Vector Gesture Stroke

Abstract

The gesture strokes are often applied to send out the manipulation commands in the free-hand sketching systems. The paper has proposed a method to identify the gesture commands from a single vector stroke. The features from the stroke and the thresholds are combined organically through a lot of testing to identify a set of gesture commands, which have been applied into an automotive 3D sketching system, AutoSketch, and gave a good performance in the real-time sketching.
