Perception of complex trajectories in Virtual Reality

We proposed a virtual reality-based experimental design for studying the human ability to intercept spinning balls deflected by the Magnus effect, like it happens in some soccer freekicks. We focused on a tight perception-action coupling. Contrary to the former studies where subjects answered only pseudo-verbally, results showed performance differences between experienced and novice groups, supporting that expertise likely appears when perception is coupled to action.

Depth perception in Virtual Reality

Using several VR-based experimental setups, we addressed human depth perception in the peripersonal space (ie. at distances reachable by hands). Our results suggest that the richness of surrounding virtual environments affects the estimation of egocentric distances to near objects (25-65 cm). Moreover, vergence cue alone (by excluding object size cue) leads to inter-individual differences in depth judgement.
