A foundation for intelligent multimodal drawing and sketching programs

Abstract

Computers should be able to assist an engineer or designer at all stages of design without chasing the engineer away or frustrating her. In order for this to occur, the computer needs to be able to understand what the engineer is doing and provide unobtrusive help. Furthermore the engineer needs to be able to interact with the computer in a natural manner. To support this design methodology I implement a foundation on which a programmer can make such applications. I provide two illustrative applications which demonstrate the foundation's power.
