In this study, we examine influence of difference in estimation method of point of gaze on evaluation of transparency during watching see-through vision. There are the two methods of estimating point of gaze, which are the method that uses the midpoint of the line segment that shows the shortest distance between the two lines of sight in three-dimensional space or the method of estimating it from intersection of two lines of sight on the two-dimensional plane. We compared these methods. As the result, there are significant differences in estimation error of convergence distance and there is relatively small variance in the three-dimensional point-of-gaze estimation methods. This result suggests that the three-dimensional point-of-gaze estimation method is more effective in evaluating transparency.
