Body ownership can be modulated through illusory visual–tactile integrations or observing mirror reflections of motor actions. We aimed to develop a method to perceive one's own invisible body in shape and action through real-time visual motions of the hands and feet contingent with observers' actions and to evaluate its effect on perception. We found that participants rated perception of their own invisible body between the hands and feet significantly higher in the vision–action contingent than in the independent condition.
