The aim of the present study is to propose the use of P300 event-related potentials as control signals in a Virtual Reality Interface. Visual stimuli, consisting of four arrows, were randomly presented in peripheral positions of a virtual environment. Users were instructed to recognize only the stimulus related to the preferred wheelchair movement direction. Our preliminary study evaluates different visual elicitation paradigms drawn from the P300 Virtual Reality Interface. © 2007 IEEE.

Abstract
The aim of the present study is to propose the use of P300 event-related potentials as control signals in a Virtual Reality Interface. Visual stimuli, consisting of four arrows, were randomly presented in peripheral positions of a virtual environment. Users were instructed to recognize only the stimulus related to the preferred wheelchair movement direction. Our preliminary study evaluates different visual elicitation paradigms drawn from the P300 Virtual Reality Interface. © 2007 IEEE.File in questo prodotto:
