角膜反射像の間隔による注視点奥行き推定と注釈提示

抄録

When a lot of information are presented using AR annotation, a user may not obtain information efficiently. Display of selected annotations around gaze point would increase visibility of annotations by reducing the amount of information. However, when gazing far area, depth error of gaze point estimation becomes highly larger than horizontal and vertical errors. In this study, a method that estimates the gaze point by calibrating depth with the distance of Purkinje images was proposed. The result of the experiments showed a significant decrease of estimation error and suggested possibility of improvement of visibility with the proposed estimation method in comparison to the traditional one.
