Immersive virtual environments (VEs) provideparticipants with computer-generated environments filledwith virtual objects to assist in learning, training, andpracticing dangerous and/or expensive tasks. But forcertain tasks, does having every object being virtualinhibit the interactivity? Further, does the virtual object'svisual fidelity affect performance? Overall VEeffectiveness may be reduced if users spend most of theirtime and cognitive capacity learning how to interact andadapting to interacting with a purely virtual environment.We investigated how handling real objects and howself-avatar visual fidelity affects performance on a spatialcognitive task in an immersive VE. We comparedparticipants' performance on a block arrangement task inboth a real-space environment and several virtual andhybrid environments. The results showed thatmanipulating real objects in a VE brings taskperformance closer to that of real space, compared tomanipulating virtual objects.
