Abstract
We propose a wearable line-of-sight detection system that utilizes micro-fabricated transparent optical sensors on eyeglasses. These sensors can detect the difference of reflection light intensity between white of eye and pupil. Up until now, we successfully have detected line-of-sight which based on 4 directions (up, down, right, left) and blink by using the practical application of our system. Our system showed experimentally that the error is as small as 1.5° in rotational angle of the eyeball. In order to develop practical application for our device, we improved our system to detect more precise eye's condition: open eye, blink, close eye. Finally, we devised an algorithm which process the information in these 3 conditions into eye state.
