This research investigates the use of virtual reality technology to improve the interaction between design engineers and their virtual prototypes during the product development process. For this, two experiments were issued to elaborate on how the factors of point-of-view and assembly rotation a ect the users three-dimensional understanding of their virtual prototype. Then, the best practices found from these experiments were incorporated into an open web platform for viewing virtual prototypes with smartphones in virtual reality. The virtual reality technology used in this work focused on the incorporation of head mounted displays to achieve a virtual experience at a lower cost than traditional CAVE systems and while being e cient with available space. The results show point of view freedom of the user inside the virtual environment signi cantly improves their ability to identify errors inside a virtual prototype when compared to having their point-of-view xed.
