“Body Ownership Transfer”, a phenomenon where the operator feels like the robot is part of their own body, is known to occur when a human tele-operate an android. We have shown that even a stronger sense of ownership transfer arises when a robot is operated by Brain Machine Interface (BMI), a system operated by the user’s brain wave. Furthermore, we have found that by biasing the feedback from the robot during BMI-Android operation, it facilitates the control of the operator’s brain wave. This notion is expected to become a new method for the Neurofeedback, and contribute greatly in improving the performance of BMI.
