Human centered and concurring product design is based on the collaboration between mechanical engineers, human factor experts and industrial designers. This collaboration is often difficult and can be eased through the use of intermediary objects such as Virtual Reality (VR). Nevertheless, even though VR is widely used in the industry, it suffers from a lack of acceptance by product designers. In the context of this research work, we suggest to use VR in the form of immersive multidisciplinary convergence support tools. These tools are developed in accordance with an anthropocentered approach, as a function of each specific product design project’s needs. In order to optimize development times, we propose a dedicated immersive software design methodology : the ASAP methodology (As Soon As Possible). A first experiment, aiming to demonstrate the feasibility of the ASAP methodology and the effectiveness of the implemented immersive tools, has been conducted in the context of industrial product design projects. A second experiment, involving more than 50 participants, has been conducted in the context of educational product design projects and led to the development of 12 immersivetools. It demonstrated quantitatively the contribution of immersive tools to the perceived effectiveness of interdisciplinary convergence phases and the contribution of the ASAP methodology on the acceptation of VR by product designers. This research work describes a first approach that could, according to us, allow abetter integration of VR within product design processes.
