摘要

For the human being, communication ability is essential for everyone. In the field of rehabilitation patients suffered by intractable diseases such as ALS(Amyotrophic Lateral Sclerosis) or Spine cord injury which can cause the damage of body's nerve cell and further result in the loss of the many functions. In order to make the communication ability possible for patients, some input devices have been commercialized. But input devices for patients under bed-ridden condition need special consideration. Directions of the patient are changed every two hours for the prevention of the bedsore. Therefore, input device should be designed to cope with this situation. Readjustment od the sensor is unfavorable. In this paper two kind of input device are proposed. A feature of these prototyped device are mounted on the face with compact body.
