Automatic Estimation Method of Relative Positions between a PC Screen and Optical Systems for Gaze Detection using Reflections of Light Sources on Small Spherical Surface

Abstract

In our gaze detection system, the relative positions between a PC screen and optical systems for gaze detection are required for accurate detection. In the present study, we proposed an automatic estimation method for determining the relative positions using the reflection images of the light sources on small spherical surface, which are attached both to the frame of the PC screen and to the optical systems.
