Perception of Symmetry of Actual and Modulated Self-Avatar Gait Movements During Treadmill Walking

In virtual reality, it is possible to simulate one's visual self-representation by mapping one's body movements to those of an avatar. Accepting the virtual body as part of one's own body creates an ownership illusion. This study aimed to assess the perception threshold between a subject's actual gait movements and those of their modulated self-avatar during treadmill walking. Preliminary results on two subjects suggest that healthy subjects can detect the mismatch, but differences may exist between subjects.
