Comparison in Depth Perception between Virtual Reality and Augmented Reality Systems

The virtual reality (VR) and augmented reality (AR) applications have been widely used in a variety of fields; one of the key requirements in a VR or AR system is to understand how users perceive depth in the virtual environment and augmented reality. This paper conducts an experiment to compare users' performance of depth perception in VR and AR system using an optical see-through head-mounted display (HMD). The result shows that the accuracy of depth estimation in AR is higher than in VR. Besides, the matching error increases as the distance becomes farther.
