由于当今移动设备的广泛使用，跟踪技术正在成为一种负担得起的商品。然而，由于漂移、延迟和抖动等问题，商用硬件中可用的所有跟踪技术都容易出错。目前对人类对静态跟踪误差感知的理解是有限的。这些关于人类感知的信息可能有助于设计跟踪系统，用于在商用硬件上显示AR和VR场景。在这篇文章中，我们介绍了一项关于人类对跟踪系统中静态方位误差的感知的研究结果，使用了两种利用手持取景器的不同设置：经典增强场景和间接增强场景。通过按场景和局部方位轴对静态定向误差进行分类，可以对用户在系统中登记定向误差的能力有新的见解。我们的结果表明，与间接AR场景相比，用户对经典AR场景中的错误有更多的感知。对于这两种情况，用户记录的侧滚方向误差不同于俯仰和偏航方向误差，并且俯仰和偏航感知高度依赖于情景。然而，AR场景中定位误差的用户表现排名是意想不到的。
Tracking technologies are becoming an affordable commodity due to the wide use in mobile devices today. However, all tracking technologies available in commodity hardware is error prone due to problems such as drift, latency and jitter. The current understanding of human perception of static tracking errors is limited. This information about human perception might be useful in designing tracking systems for the display of AR and VR scenarios on commodity hardware. In this paper we present the findings of a study on the human perception of static orientation errors in a tracking system, using two different setups leveraging a handheld viewfinder: a classical augmented scenario and an indirect augmented one. By categorizing static orientation errors by scenario and local orientation axis, new insights into the users' ability to register orientational errors in the system are found. Our results show that users are much more aware of errors in classical AR scenarios in comparison to indirect AR scenarios. For both scenarios, the users registered roll orientation errors differently from both pitch and yaw orientation errors, and pitch and yaw perception is highly dependent on the scenario. However, the users performance ranking for orientational errors in AR scenarios was unexpected.
