Feature-Gestures Modeling of Sketch in Conceptual Design

The concept of feature gesture is given and feature gesture base is set up.The modeling process based on feature gesture is described.Furthermore‚the constraint capture‚solution algorithm and the context-awareness are discussed.By comparing the method with traditional mode‚we can see that feature gestures are convenient and efficient for modeling.The method can make the interactive interface more natural and more intuitive‚and simplify designing process‚allowing designers to express design intention fluently.By the way of user-centered design‚this method can improve human-computer interaction in designing process.
