Severely handicapped uses ECS (environmental control system) to control electrical appliances such as TV, motored bed, curtain, air conditioner in everyday life. The input of the usual ECS is typically ON/OFF by some switches to control the equipment. However, such ECS can not be used for the machines which need real-time analogue input, such as an electrically-powered wheel chair. The paper, thus proposes a new input method for ECS to enable the real-time analogue interface. The method uses an expiration pressure sensor as an analogue input device. Comparison of performances between manually operated control stick and the expiration pressure sensor is shown. Then effectiveness of the proposed input method is discussed.
