A Study on Line of Sight Detection Using Color Contact Lenses

摘要

In this paper, we propose a method of LOS detection using color contact lenses, which are relatively unobtrusive from the user's perspective, together with image processing. Taking the principle that movement of contact lenses is equivalent to changes in line of sight, we detected the position of the eyeball and the orientation of the lens on two axes using image processing, and transformed these values into line of sight values. We actually produced the color contact lens we designed for this study, and conducted line of sight detection experiments employing human subject.
