Abstract
This paper describes a gesture input interface using combination of head and eye movement. We develop a headphone device that can perform simultaneous measurement of the head and eye movement. The head motion is detected by an accelerometer and gyro sensor, and the eye movement, by a bio-potential amplifier as electro-oculogram (EOG). A major problem of such an interface is Midas touch problem, that some gesture motion becomes artifact and causes an unintended input. In order to reduce the influence of motion artifacts and solve the Midas touch problem, we perform experiments to evaluate daily motion such as "reading a book" in sitting on a chair. In addition, the motion, "gazing a target with head movement", is tested as a gesture movement. The present experimental results show that the eye movement in the yaw direction gives a large signal. It is caused by vestiburo ocular reflex (VOR) is frequently observed in the yaw direction during the gesture motion.
