Eye-screen distance monitoring for computer use
Caillin Eastwood‐Sutherland, Timothy J. Gale · 2011
The extended period many people now spend looking at computer screens is thought to affect eyesight over the long term. In this paper we are concerned with developing and initial evaluation of a wireless camera-based tracking system providing quantitative assessment of computer screen interaction. The system utilizes a stereo camera system and wireless XBee based infrared markers and enables unobtrusive monitoring. Preliminary results indicate that the system is an excellent method of monitoring eye-screen distance. This type of system will enable future studies of eye-screen distance for computer users.
