Abstract
Visuospatial functions play a crucial role in human
cognition, which has elicited over years a great deal of research
focusing on their assessment, training and restoration. Interestingly,
although our visuospatial capacities allow us to understand
and infer relationships of 3D objects in space, these 3D aspects
of visuospatial processing are profoundly neglected in laboratory
tests, and instead, 2D designs are commonly used. Aiming to
increase the ecological validity of such tests, we propose an
experiment to evaluate the capacity of a 3D virtual space to
stimulate cognitive functions. The experiment involves cognitive
testing, EEG measurements, and cognitively stimulating tasks in
an immersive 3D virtual environment rendered by a unique CAVE
system. This paper focuses primarily on two game prototypes that
will serve as the virtual environment and describes a natural
movement control using the Myo armband, incorporated into
one of the games. We also briefly discuss cognitive testing design
using the selected brain electrophysiological variables measured
on human subjects before and after the virtual reality game use,
in order to assess the potential effect of the game.
