Length perception in virtual reality environment

Today simulation platforms in Virtual Reality Environment (VRE) play a very important role during the initial design phase of products throughout the Product Life-Cycle (PLC). However, current simulation platforms do not offer the necessary information and versatility required for a complete perception process in simulation and evaluation. This paper deals with a new method for measuring the influence of Virtual Reality on the perceived length of an object (e.g. a bar). The method is based on the assessment of the length of a part by the subject, with two sources of visual information. The first one is the screen of the VRE where the movements are displayed, with different coefficients Ceb=(object length displayed on the screen)/(length of the arm’s movement). The other source is a set of two crossed meters (measuring tapes) situated on the wall behind the subject. The method is validated by a set of experimental tests performed in a Virtual Reality Environment. The results show that subjects are more likely influenced by the movement of the arm rather than the length of the arm displayed on the screen. Moreover, the length’s perception of subjects is modified when moving direction changes (horizontal or vertical) or when putting/placing a meter (measuring tape) in the subject’s field of view. The horizontal bar or the meter (measuring tape) leads them to choose lengths closer to what they are seeing on the screen, than when the bar is vertical or without meter. The proposed method provides the feasibility to integrate the visual perception into length evaluation via VRE when performing disassembly operation simulations for instance.
