当环境尺度（大小和距离）被准确感知时，中介环境的效用会增加。我们提出了使用感知的启示-判断的行动能力-作为一种客观的方式来评估空间感知的增强现实（AR）环境。目前的研究将这种方法在虚拟现实（VR）中的应用扩展到了AR。我们测试了两个基于运动的启示任务。在第一个实验中，观察者判断他们是否可以通过以不同宽度和距离呈现的虚拟光圈，并且还判断到光圈的距离。在第二个实验中，观察者判断他们是否能跨过地面上的一个虚拟缺口。在这两个实验中，虚拟物体都是在真实的实验室环境中用HoloLens显示的。我们表明，通过和感知距离的光圈是类似的AR在真实的世界中测量的启示，但在AR的跨越间隙的判断被低估。跨两个示能表示的这些差异可由虚拟对象的不同空间特性（在地面上相对于延伸离开地面）引起。
The utility of mediated environments increases when environmental scale (size and distance) is perceived accurately. We present the use of perceived affordances---judgments of action capabilities---as an objective way to assess space perception in an augmented reality (AR) environment. The current study extends the previous use of this methodology in virtual reality (VR) to AR. We tested two locomotion-based affordance tasks. In the first experiment, observers judged whether they could pass through a virtual aperture presented at different widths and distances, and also judged the distance to the aperture. In the second experiment, observers judged whether they could step over a virtual gap on the ground. In both experiments, the virtual objects were displayed with the HoloLens in a real laboratory environment. We demonstrate that affordances for passing through and perceived distance to the aperture are similar in AR to those measured in the real world, but that judgments of gap-crossing in AR were underestimated. These differences across two affordances may result from the different spatial characteristics of the virtual objects (on the ground versus extending off the ground).
