摘要：与真实的世界相比，在增强现实（AR）中观察物体时，视觉感知距离是否不同？有什么不同？这些问题在理论上很有趣，答案对于许多基于平板电脑和手机的AR应用程序的开发非常重要，包括移动的AR导航系统。本文介绍了一个彻底的文献综述距离判断实验协议，并从知觉心理学的几个领域的结果。除了真实的和虚拟对象的距离判断之外，本节还讨论了先前在测量虚拟图片空间的几何形状方面的工作，并考虑了这项工作如何与平板电脑AR相关。然后，本文介绍了两个实验的结果。在每个实验中，观察者在基于平板电脑的AR和真实的世界中，在室内走廊和室外场地环境中平分15米和30米的自我中心距离。在AR中，观察者将与虚拟人的距离一分为二，而在真实的世界中，他们将与真实的人的距离一分为二。这是第一个报告的研究，直接比较了平板电脑AR系统中真实的和虚拟物体的距离判断。研究发现：（1）在AR中，观察者在15 m处扩大了中点间距，但在30 m处压缩了中点间距。(2)观察者在真实的世界中是准确的。(3)环境设置走廊或开放领域没有影响。(4)图片感知文献对于理解如何在基于平板电脑的AR中判断距离非常重要。总的来说，这些发现表明了AR应用程序开发人员在移动的，特别是基于平板电脑的AR中应该预期的深度失真。
ABSTRACT Does visually perceived distance differ when objects are viewed in augmented reality (AR), as opposed to the real world? What are the differences? These questions are theoretically interesting, and the answers are important for the development of many tablet- and phone-based AR applications, including mobile AR navigation systems. This article presents a thorough literature review of distance judgment experimental protocols, and results from several areas of perceptual psychology. In addition to distance judgments of real and virtual objects, this section also discusses previous work in measuring the geometry of virtual picture space and considers how this work might be relevant to tablet AR. Then, the article presents the results of two experiments. In each experiment, observers bisected egocentric distances of 15 and 30 m in tablet-based AR and in the real world, in both indoor corridor and outdoor field environments. In AR, observers bisected the distances to virtual humans, while in the real world, they bisected the distances to real humans. This is the first reported research that directly compares distance judgments of real and virtual objects in a tablet AR system. Four key findings were: (1) In AR, observers expanded midpoint intervals at 15 m, but compressed midpoints at 30 m. (2) Observers were accurate in the real world. (3) The environmental setting—corridor or open field—had no effect. (4) The picture perception literature is important in understanding how distances are likely judged in tablet-based AR. Taken together, these findings suggest the depth distortions that AR application developers should expect with mobile and especially tablet-based AR.
