The effect of lip and arm synchronization on embodiment: A pilot study

We are interested the effect of lip and arm synchronization on body ownership in VR (the illusion that the users own a virtual body). Participants were invited to give a presentation in an HMD, while seeing in a virtual mirror a gender-matched avatar who copied their arm and lip movements in sync and a-sync conditions. We measure participants' reaction with questionnaires administrated verbally after their presentation while immersed in VR. The result suggested an interaction effect of arm and lip, showing reports of higher level of embodiment with the congruent as compared to the incongruent conditions. Further study is needed to confirm if the same interaction effect can be captured with objective measurements.
