Computer Support for Conceptional Design

In this paper, requirements with respect to computer support for early design phases in product development are discussed. Here, support for quick engineering sketches and note taking plays an important role. As an approach to a solution, the architecture of the system GRIPSS, a Graphical Idea Processing and Sketching System, developed at the Computer Science Institute of Stuttgart University, is introduced. Then the sketching editor of this system is described in more detail. In particular the methods used for the interpretation of the hand drawn input are presented and characterised. Eventually, some prospects for further developments are given.
