This paper adresses the issue of properly designing a digital mockup (DMU) to be used in an experiment comparing simulated assembly tasks in both real and virtual environments. Motivations and specifications relative to the experiment are reported, and the design process of the DMU is described and illustrated. Recommendations are proposed with a particular focus on specificities relative to the use of a DMU as a support for both manufacturing and virtual reality-3D visualisation and interaction. A subjective evaluation of Real (RE), Virtual (VE), and Virtual with Force Feedback (VEF) environments is provided. Results indicate a real sensory and difficulty gap between RE and VEF, whereas a smaller difference was observed between RE and VE. In further improvements of scale-1 (where the objects in VE have the same size as in the real environment), colocalized simulation using haptic devices are warranted to fill in this gap. Results also highlight the impact of cognition and sensory feedback on user's feeling and presence sensation. Applications of such numerical designs are presented in the last section, especially focusing on collaborative design sessions. Virtual Reality based evaluation of newly designed workstations will be a way in the future to improve design and user learning processes.

The aim of this paper is to evaluate two new operating design modes and their collaborative metaphors enabling two actors, a design engineer and an end-user, to work jointly in a collaborative virtual environment for workstation design. The two operating design modes that correspond to two different design paradigms include : direct design mode (the design engineer manipulates objects while the end-user specifies their activity constraints) and supervised design mode (the end-user manipulates objects while the design engineer specifies their process constraints). The corresponding collaborative metaphors enable the two actors to manipulate objects while one (the design engineer) can express process constraints and the other (the end-user) can express activity constraints. The usability evaluation of the modes and metaphors consisted in placing a workstation design element on a digital workstation mock-up where a trade-off was to be found between process constraints and activity constraints. The results show that if we consider the completion time as the most important criterion to achieve, the direct design mode must be favoured. Otherwise, if the activity constraints are predominant, the supervised design mode must be favoured. In any case, the addition of an ergonomist's point of view is supported and warranted in order to enhance the effectiveness of the system.
