Virtual reality shows to be of use in several domains of manufacturing as a complementary tool to CAD/CAM environment. Design review is one of the very first application of VR in product design, but assembly/disassembly studies are also existing though they require some more specific work. But it can also be useful beyond the scope of common CAD software such as ergonomic studies. We will show an example from the RNTL PERF-RV project where we study the ergonomics of a car dashboard and more specifically of a push-button. We will discuss the issues raised by studying ergonomics thanks to Virtual Reality and force-feedback systems which are both hardware and software.
