增强现实（AR）通常是通过智能手机或平板电脑等移动设备体验的。在真实环境中定位虚拟目标的准确性对于导航和训练等任务非常重要。在本文中，我们通过移动设备的AR平台测试了用户对室内和室外环境中呈现的虚拟物体的距离感知（10-40米）。此外，我们通过移动设备测试了用户对真实物体距离的感知，作为基线比较。虽然真实目标和虚拟目标的40米距离被同样低估，但在较近的距离上，虚拟目标被判断为比真实目标更远。环境背景对观看条件和距离估计都没有影响。我们讨论了我们的发现对需要精确距离感知的移动增强现实应用的影响。
Augmented reality (AR) is commonly experienced through a mobile device such as a smartphone or tablet. Accuracy in locating virtual targets in real environments can be important for tasks such as navigation and training. In this paper, we tested users’ perception of distances (10-40m) to virtual objects presented in both indoor and outdoor environments through an AR platform for a mobile device. In addition, we tested users’ perception of distances to real objects through the mobile device as a baseline comparison. Although the 40m distance was underestimated similarly for both real and virtual targets, the virtual target was judged to be farther than the real target at the closer distances. There was no effect of environmental context on either viewing condition or distance estimation. We discuss the implications of our findings for mobile augmented reality applications that require precise distance perception.
