영문 초록

  Those who suffer from ALS disease show impairments in motor functionality that often impedes communicating actions such as uttering voice and pushing buttons. In order to support their communication, this paper presents two kinds of input devices based on vision. A distinct advantage of these devices is that it could be installed without respect to the bed of the patient. This means the devices do not interfere with the nursing care. The first device is applicable to the switching action generated by slight movements of the user"s body, like lips, fingers, or eyes. This device is suitable for ALS patients with serious physical disability. The second device is developed for ALS patients who have ability to move his head intentionally. The head movement is measured by an original compact vision system, and converted into the mouse motion on the computer screed. This device enables fast input operations. Both these devices have been applied to ALS patients, and their effectiveness has been verified.
