虹彩輪郭の楕円近似を用いた非接触視線検出法の研究(機械力学,計測,自動制御)

Human interfaces are a necessary technology in this information-oriented society, and comfortable operation for the user is desired. It is thought that line-of-sight (LOS) detection technology will allow significant advances in this field. In this study, we developed a non-contact LOS detection method using the ellipse fitted to the iris edge. This method does not require the user to wear markers or other devices, and requires less equipment than other systems. Using image processing, the feature points of face and the ellipse fitted to the iris edge are extracted. The detected data of the feature points are transformed into the LOS. Evaluative experiments were conducted using a dummy head and a plastic model of an eye, and with human subjects. We obtained the degree of precision needed for practical application, and demonstrated the workability of our LOS detection algorithm.
