In this report, we propose the bi-state operating controller for the electric wheelchair using the information on the motion of operator's head as the one proposal for the diversification of controller device of electric wheelchair. The proposed controller employs two information on the driving direction and one extra information on the decision making. The formers are based on the motion of operator's head,' the bending motion for forth, and the rotating motion for right and left. And the later is based on the biting motion for the decision making. This extra signal is detected by the change of optical rubber fiber sensor and makes the whole control system safer than the ordinary controller using the motion of head. All of signals are changed into the binary signals comparing with a threshold level to improve the reliability of controller. Much lower threshold level results the erroneous behavior because of the higher sensitivity, and much higher one lets the operators move their head large. We proposed the designing methodology of the threshold level with analyzing the behavior of head movement The knowledge and view on the proposed system is discussed.
