We present the results from a qualitative and quantitative user study comparing fishtank virtual-reality (VR) and CAVE displays. The results of the qualitative study show that users preferred the fishtank VR display to the CAVE system for our scientific visualization application because of perceived higher resolution, brightness and crispness of imagery, and comfort of use. The results of the quantitative study show that users performed an abstract visual search task significantly more quickly and more accurately on the fishtank VR display system than in the CAVE. The same study also showed that visual context had no significant effect on task performance for either of the platforms. We suggest that fishtank VR displays are more effective than CAVEs for applications in which the task occurs outside the user's reference frame, the user views and manipulates the virtual world from the outside in, and the size of the virtual object that the user interacts with is smaller than the user's body and fits into the fishtank VR display. The results of both studies support this proposition.
我们展示了一项定性和定量用户研究的结果，该研究比较了鱼缸式虚拟现实（VR）和CAVE显示器。定性研究结果表明，在我们的科学可视化应用中，由于用户认为鱼缸式VR显示器的图像分辨率、亮度和清晰度更高，且使用更舒适，因此用户更喜欢鱼缸式VR显示器而非CAVE系统。定量研究结果表明，与在CAVE中相比，用户在鱼缸式VR显示系统上执行抽象视觉搜索任务的速度明显更快，准确性更高。同一研究还表明，视觉上下文对这两个平台的任务性能均无显著影响。我们建议，对于任务发生在用户参考框架之外、用户从外部向内查看和操作虚拟世界、且用户与之交互的虚拟对象的大小小于用户身体并适合鱼缸式VR显示器的应用，鱼缸式VR显示器比CAVE更有效。两项研究的结果均支持这一观点。
