Abstract

Pre-existing researches [Salamin et al. 2006] showed that Third-Person Perspective (3PP) enhances user navigation in 3D virtual environments by reducing proprio-perception issues. Nevertheless, this approach has shown drawbacks related to occlusions and adaptation time. The perspective proposed in this paper - our Improved Third-Person Perspective (i-3PP) - does allow the user to see through his/her body in order to fix 3PP limitations like occlusions. As gamers prefer using 3PP for moving actions and the First-Person Perspective (1PP) for fine operations, we verify if this behavior is extensible to simulations in augmented and virtual reality. Finally we check if the i-3PP would be preferred to the other perspectives for any action.
