Our previous studies have proposed active self-touch in which experimental participants can voluntarily touch a fake/virtual body as well as their own body by using a robotic master-salve system when experimentally manipulating sense of body ownership. This paper introduces a novel experimental platform that can control temperature displayed to the real and fake bodies by means of thermal displays in active self touch. Using the experimental platform, we aim at revealing whether the sense of body temperature is essential for human body perception and how much temperature difference between the real and fake/virtual bodies is acceptable to consider the fake/virtual body as our own body. In the present study, the basic characteristics and performances of the developed platform were evaluated and the applicability to manipulate the sense of body ownership was verified by conducting a simple cognitive neuroscientific experiment.
