An examination on eye-gaze input using a bubble cursor in AR

Abstract

In recent years, research on augmented reality (AR) has been active, and eye gaze input has attracted attention as one of the input methods in AR. One problem with gaze input is that it is difficult to input when the target is small or crowded. In response to this problem, the bubble cursor facilitates eye gaze input by changing the size of the circular cursor according to the distance to the nearest target. In addition, by using the distance from the eyeball to the point where the lines of sight of both eyes intersect, called the convergence distance, it is believed that the user's gazing point can be accurately determined without relying on collision determination with virtual objects. In this study, we use the convergence distance to determine the gazing point in an AR environment and consider the bubble cursor centered on the gazing point.
