ADELE : une architecture à base de tableau noir pour la simulation ergonomique

Abstract : The ergonomic evaluation of computer assisted design prototypes of systems like cars or trucks requires simulation tools, in order to assess the convenience of the product for its future users. 3D graphic mannequins are such simulation tools, which provides facilities for fit vision and reach tests. These tools prove to be very useful, however the use of the tools is in fact not easy at ail due to the large amount of expertise needed to manipulate them. Furthermore, the user must possess a great amount of expert knowledge to decide, on the basis of the mannequin posture, whether he has chosen a good implantation for the elements of the product, or not. We analyse the existing ergonomic simulation tools, then we propose a new approach, based on the automation of the mannequin handling and the add of ergonomic assessment tools. We propose a motor activity model (which provides a tool for the specification of the tasks to be simulated by the mannequin) and knowledge bases (for movement strategies and ergonomie diagnosis). The system is based on a bJackboard architecture which helps to model the control aspects (mannequin handling and production of an ergonomic diagnosis). The prototype of our system, ADELE, has three components : a graphical human model, MAN3D (developed at INRETS/LESCO), an object database (developed with GemStone DBMS) and a blackboard system (deveJoped with Atome, a LORIA-Nancy tool). A specific link between Atome and GemStone has been developed, which allows to implement a blackboard located in the object database.
