Abstract

Feeling body ownership over a fake body image in video games or virtual environments may enhance the immersion and feeling of presence in them. In these situation, the sharpness of the image may influence the induction of the body-ownership illusion. In this study, we investigated the effect of blurring the image on the rubber hand illusion experience under seven levels of blur intensity. The results showed that blurring the image within the limits of hand recognizability may induce stronger body ownership of the fake hand but may not influence agency. This indicates that body ownership of a body image can be controlled by the sharpness of the presented image.
