Conception d'une interface tangible pour l'assemblage en CAO

摘要

In this paper we present an operational tangible user interface dedicated to the mechanical CAD (Computer Aided Design) parts assembly. This platform is mainly based on the handling of physical objects. In our application field we show that our physical objects lead to take into account assembly constraints from the beginning of the design phase and especially during the phase of CAD model manipulation. We show how the use of our platform leads the designer to have a physical perception of the assembly constraints during the "virtual" phase of design on computer.
