A pillow type computer input device is proposed. The interface is designed to move computer\ncursor as the user expect by using his or her head movement. A supporting and care devices\naround the bed often becomes barriers for the care and assist task for the patient. The proposed\npillow type interface is designed not to disturb the care and assist tasks. The head movement of\nthe user is estimated by the four pressure sensors under the pillow. In order to improve the user friendliness\nof the interface, the pillow is mounted on the sliding mechanism. Due to these pressure\nsensors, rotating head movement around the neck and nodding movement of the head can be\nmeasured quantitatively. Considering the head movement, the computer cursor is moved by using\nthe original algorithm.
