第二十届中国虚拟现实大会 (ChinaVR 2020)

Interactive techniques in Virtual Reality (VR) is rapidly developing in the recent years. However, the consistency of the interaction activities in VR and real-world remains a subject to be further studied. In this work, we study the consistency of casting action between VR and real-world. In our experiments, we let participants cast a ball to a walking human virtual agent, which is driven by a motion capture system in the virtual environment. By comparing to the casting accuracy in real-world, we observe that the participants' performance under various of the experimental configurations is consistently reduced in VR. We also found that the moving 'speed' factor of the casting target barely affected the accuracy in VR, which was different in the real-world environment. This study will provide an important experimental reference to develop future VR systems based on casting actions.
