我们报告了一系列的实验进行调查的影响，旅游技术的信息收集和认知在复杂的虚拟环境。在第一个实验中，参与者使用真实的行走或两种虚拟旅行技术之一来按照自己的节奏完成一个无分支的多级3D迷宫。在第二个实验中，我们构建了一个带有分支路径的真实迷宫，并模拟了一个相同的虚拟环境。参与者使用真实的行走或虚拟旅行技术在预定的时间内探索真实的或虚拟迷宫。我们的实验结果表明，对于需要大量转弯的复杂环境，如果应用程序的目标涉及基于虚拟世界中提供的信息进行学习或推理，则虚拟旅行是真实的步行的可接受替代品。然而，对于需要快速、高效的导航或与真实世界行为非常相似的旅行的应用，真实的步行比常见的基于地图的虚拟旅行技术具有优势。
We report a series of experiments conducted to investigate the effects of travel technique on information gathering and cognition in complex virtual environments. In the first experiment, participants completed a non-branching multilevel 3D maze at their own pace using either real walking or one of two virtual travel techniques. In the second experiment, we constructed a real-world maze with branching pathways and modeled an identical virtual environment. Participants explored either the real or virtual maze for a predetermined amount of time using real walking or a virtual travel technique. Our results across experiments suggest that for complex environments requiring a large number of turns, virtual travel is an acceptable substitute for real walking if the goal of the application involves learning or reasoning based on information presented in the virtual world. However, for applications that require fast, efficient navigation or travel that closely resembles real-world behavior, real walking has advantages over common joystick-based virtual travel techniques.
