summary |
From the early steps of sketching to final engineering, a frequent and very important activity in designing objects is to perform graphical and spatial simulations to solve the constraints on the objects which are being designed. But when we analyse work situations involving the use of CAD systems, it is today an acknowledged fact that these tools are not helpful to perform these types of simulations. While knowledge modeling based on form feature concepts already offers some possibilities for attaching behaviour to objects, the simulation activity requires in addition a `real time' and `intelligent' management of the interactions between the 3D virtual objects and the CAD user. Our general purpose is to study how future CAD systems could be improved to achieve the simulation steps of object design. In this context we present some issues concerning the cooperation between a model of reactive 3D objects and a multimodal X Window kernel. We have developed a prototype of a system where objects with reactive behaviour can be built, and with which the user can interact with a combination of graphical actions and vocal commands. This prototype is used to evaluate the feasability and the usefulness of the integration of such techniques in futur applications that would be used by object designers in a real working context. We describe the current state of this system and the planned improvements. |
