Manipulation of human bodily self-consciousness using haptic interface and its application

The major contribution of this study is to allow new approaches for the manipulation of bodily self-consciousness, which is one of the recent hottest topics in cognitive neuroscience, by applying robotics/haptics technology. In particular, a new stimulation method termed as active self-touch that allowed experimental participants to synchronously or asynchronously touch a virtual body and their own body by using a robotic master-slave system was proposed and implemented in Full Body Illusion (FBI) paradigm as well as Rubber Hand Illusion (RHI) paradigm. The new stimulation method with force display function enabled us to examine and discuss how action (the sense of agency) or force sensation affected the sense of body ownership. Also, we could obtain new findings about the human bodily self-consciousness and future possibility for cognitive neuroscience studies.
