| Popis: | 107 Virtual Reality (VR) technologies have been applied to various domains, e.g., games, simulation, teleoperations, product design, training, and education. In these applications, spatial perception is important especially when the users need to estimate distance accurately, like driving training. However, there exists an issue of distance compression in VR, i.e., people perceive a distance nearer in a virtual world than that in the real world. The VR applications would benefit from our perception of distance in the VR being as close as possible to that in the physical world. Many factors of distance compression have been discussed, but they could just partially explain the phenomenon. Moreover, most of the existing solutions approach this problem from the visual aspect and suffer from some drawbacks such as image distortion, needing individual pretest, or needing a real room replicating a virtual environment. In this study, we propose a method to compensate distance perception in VR by increasing reverberation time (RT). Our findings reveal that participants can associate longer RTs with farther distances in the range of 1 to 10 meters. Furthermore, distance compensation by reverberation affects participants more in near distance range (than the far range) and with short RT (than with long RT). Reverberation can potentially be used as an effective means to compensate distance compression in VR. |
