Abstract:
With the spread of Head-Mounted Displays (HMDs), various simulations have been conducted using Mixed Reality (MR) environments that merge virtual objects in a physical space. Our Three-Dimensional (3D) perception may change as opportunities to have more virtual 3D experiences in such an environment increase. The relationship between differences in depth perception and changes in 3D gaze behavior would be of interest, but such detailed analysis is yet to be conducted. In this study, we developed an Optical See-Through Head-Mounted Display (OST-HMD) and experimentally evaluated the effect of an MR environment on 3D gaze measurement. Our experiments showed that the relative size of the 3D visual targets and the surrounding depth cues had no effect on the accuracy of the 3D gaze. However, it is important to consider the building of a polynomial for projecting the 3D gaze, and there is room for improvement in the polynomial. We have successfully measured the scanpath of 3D gaze on a visual target approaching from 200 cm. This result suggests that our OST-HMD can measure 3D gaze in the personal space, defined by Cutting (1997) as a space up to 1.5 m from the viewer.
