CHAPITRE D'OUVRAGE (CO)
Résumé / Abstract
We describe an application of artificial intelligence techniques in the field of computer aided workplace design, especially for vehicles. The idea is to provide designers with ergonomic knowledge. During the design process, they first built a cad model, on the basis of technical constraints. Then they try to take into account ergonomic considerations in order to ensure the usability of the product. For that they commonly use graphical models of the man. Our starting point was one of these models, called man3d, developped at inrets/lesco with classical computer science techniques. As an articulated figure, with joint limits, it allows the user to obtain a good human representation and to simulate simple gestures. But the user has no way to control the realism of his simulation. The first objective of the project was to complete the model, in order to improve the realism of postures and gestures, especially by taking into account the environmental characteristics. The second objective was to add a final diagnosis to the simulation. We describe here our solution, the adele system, based on a multi-agent system with a blackboard architecture, connected to an object-oriented database. The multi-agent system generator atome is used to develop adele.
