Abstract
A man-machine interface using EMG and EOG bio-potential signals for controlling one-axial positioning system is developed. Relationship between chewing force and EMG signal has linearity. EOG signal is in proportion to acceleration of eye movement. EMG signal is used for on-off switching and time integration of EOG signal with dead band is used for servo motor input signal. Experimental results of operation show that beginner is not easy to operate the one-axial positioning system with a servomotor. However, after training the operator can control the servomotor system by using the man-machine interface. This system is easy to extend more complex systems such as multi-degree of freedom robots.
