Abstract:
Recently, Head-Mounted Displays (HMDs) have become popular, making it easier to experience Mixed Reality (MR) environments that fuse real and virtual space. With the ability of MR to locate virtual Three-Dimensional (3D) objects in the real space, our 3D perception may also change as this type of 3D experience increases. While there have been studies that measure 3D gaze in either virtual or real space, no studies have discussed how the MR affects 3D gaze. In this study, we developed a See-Through Head-Mounted Display (ST-HMD) to analyze the effect of MR environment on 3D gaze measurement. We conducted experiments in two different physical environments: a room with and without depth cues. Our results showed that there was no significant difference in the measured 3D gaze between rooms with and without depth cues. Experiments of tracking the gaze of a visual target moving from back to front showed that the scanpath of the 3D gaze followed the trajectory of the target's movement.
