Remarks on hands-free manipulation using bio-potential signals

This paper proposes a nonverbal interface system using bio-potential signals, such as EOG and EMG, measured by a brain-computer interface and investigates its possibility of application to control of a hands-free manipulation system. A simple gesture recognition algorithm is presented to estimate the user´s intentions/thoughts from the EOG and EMG signals. To evaluate the feasibility and the characteristics of the nonverbal interface system, moving control experiments in 3D virtual space are carried out and the effectiveness of the proposed interface system is confirmed.
