Abstract: Combining the flexibility and ease of use of paper and pencil with the processing power of the computer, computer aided sketching design(CASD) technology specially suits for conceptual design and can help designer write down design ideas rapidly. For many years it has been one of the key issues on which many specialists and scholars have research. Based on application domains of sketching technology, the present situation of CASD is introduced. From four aspects of CASD, that is user interface design, low level sketch process, high level sketch interpretation, 3D sketching modeling, research method of some key technologies of CASD are analyzed. The development tendency of CASD is predicted.

Key words: Conceptual design, Sketching design, Gesture, Recognition
