Presence and the sense of embodiment are essential concepts for the experience of our self and virtual bodies, but there is little quantitative evidence for a relation between these, and this relation becomes more complicated when there are real and virtual bodies in augmented reality (AR). We investigate the experience of body ownership, agency, self-location and self-presence in AR where users can see their real body and a virtual body from behind. Active arm movement congruency and virtual anthropomorphism are varied. We found significant effects of movement congruency but not anthropomorphism, a strong correlation between self-presence and body ownership, and a moderate correlation between self-presence and agency and self-location.
