Abstract

This paper presents a framework of sketch editing environment for conceptual design process based on context. It analyzes the characteristics of design process and presents sketch description model for sketch based interface. Furthermore, it discusses the context fusion methodologies and algorithms to infer design context to understand designers' intent and communicate with designers intuitively. The context mainly is related to user, environment, and machine. A sample application is given to conduct the process planning drawings by sketching, exploring and modifying their ideas interactively, with immediate and continuous visual feedback. In the paper, we aims to study designing a sketch based interface enabling both computer and designer aware of underlying design contexts and providing intelligent operations.
