Research on collaborative interaction based on gesture and sketch in conceptual design

This work presents an interaction pattern based on gesture and sketch. It provides a natural and harmonious user interface for collaborative operation in conceptual design, which enhances the development and application of collaborative system. Based on user-centered design, this paper analyzes different conceptual design process and gives a collaborative design method based on gesture and sketch; it makes deep research on product information carrier based on sketch; citing the gesture operation, it provides the collaborative context-awareness and the description model; it discusses the sketch interaction design for synchronous edit and the bidirect constrain solution is put forward. This paper provides a convenient method of collaborative design to develop design efficiency and improve human-computer interaction.
