This paper reports on the findings of a study about perception in virtual contexts, conducted with 111 persons from 4 countries. Perception constitutes one of the key cognitive learning process. In this study, we aimed at assessing whether items displayed in a VR360 video context were more rapidly perceived compared to a VR 3D environment. Results showed that for the considered sample, items displayed were more rapidly perceived in a VR 3D environment than a VR 360 video environment. Women were slower than men, but with a shorter perception gap for the VR 360 video than the VR 3D. The elder the people, the less performing the perception becomes, both in 360 and in VR 3D, but more efficient in VR 3D than in 360. These results will help design visual environments adapted to virtualized experiential learning simulations.
