Аннотация:Various studies have proved that the consistency of information within modalities would affect Presence Effect in virtual environments (Slater, 2003). We investigated the subject’s respond to a mismatch between visual and proprioception information while perceiving a self-avatar. The CAVE virtual reality system and the embodiment technology were used to create interaction with a self-avatar. The experiment consisted of two parts. In the first part the participants were asked to carry out body movements that were exactly copied by their own avatar displayed in front of them. The exercises should be repeated a number of times for 3 minutes to persuade the participants of being embodied in their own avatar. In the second part the participants could perceive the discrepancy between their own body movements and movements of the avatar. The physiological reactions (summary EMG activities) were recorded during the performance to measure the degree of interaction between the participant and her/his own avatar. The results showed that EMG activities were significantly higher while perceiving a mismatch between visual and proprioception information. Our data may be used to improve the measure of Presence Effect in virtual environments.
