Brain activity underlying third person and first person perspective training in virtual environments

Over the years, different approaches have been explored to build effective learning methods in virtual reality but the design of effective 3D manipulation techniques still remains an important research problem. To this end, it is important to quantify behavioral and brain mechanisms underlying the geometrical mappings of the body with the environment and external objects, both within the virtual environments (VE), the real world and relative to each other. The successful mapping of such interactions entails the study of fundamental components of these interactions, such as the origin of the visuo-spatial perspective (1PP, 3PP) and how they contribute to the user's performance in the virtual environments. Here, we report data using a novel set-up exposing participants - during free navigation - with a scene view from either 3PP or the habitual first-person perspective (1PP).
