Abstract
This paper presents the latest results on a wearable line-of-sight (LOS) detection system using transparent optical sensors on eyeglasses. A successful LOS detection system that enables a plenty of promising applications must cause the user least stress to acquire effective information. The proposed system herein detects the position and movement of eyes by the sensors and does not require an external camera facing eyes, which alleviates both mental and physical stress on the subject. Dye sensitized photovoltaic cells were micro-fabricated and used as the transparent sensors. Fabricated photovoltaic cells were characterized and an algorithm to acquire the position and movement of the pupil was developed. The system successfully detected the center of the pupil with errors of ±3.0º and then deduced the LOS.
