虚拟现实（VR）演示的使用正成为向大量观众传达信息和显示数据的越来越频繁的手段。VR演示对视觉、听觉和触觉信息的再现提出了很高的要求。VR演示中常见的情况是，一个演员在虚拟环境（VE）中行动，而一群人在VE中观察演员的行动，通常是从演员的角度出发。本文旨在研究参与者（参与者主动与虚拟现实互动）和观察者（参与者被动观察，参与者与虚拟现实互动）对虚拟现实呈现的评价。在一项实验中，16名演员和16名观察者要么在VE中表演，要么在VE中观察，并对演示的质量进行评级。结果显示，演员体验到更高的临场感和真实感，并且比观察者更享受VR体验。另一方面，观察者则认为外部事件比演员更容易分散他们的注意力。最后，演员们经历了更多的模拟病症状。然而，演员和观察者对音频质量的评分并没有差异。
The use of virtual reality (VR) presentations are becoming a more and more frequent means of communicating information and displaying data to large groups of viewers. VR presentations put heavy demands on reproduction of visual, aural, and tactile information. A common situation in VR presentations is that one actor acts in the virtual environment (VE), while a group of people observes the actors actions in the VE, often from the perspective of the actor. The current paper aims to study actors' (participants actively interacting with the VE) and observers' (participants passively observing; the actors' interaction with the VE) evaluations of the VR presentation. In an experiment, 16 actors and 16 observers either acted in or observed a VE and performed ratings of the quality of the presentation. The results showed that actors experienced higher presence and realism, and enjoyed the VR experience more than observers did. Observers, on the other hand, experienced that external events distracted their attention more than actors did. Finally, actors experienced more symptoms of simulation sickness. However, no differences between actors and observers were found for ratings of audio quality.
