This paper presents the results of two cognitive load studies comparing three augmented reality display technologies: spatial augmented reality, the optical see-through Microsoft HoloLens, and the video see-through Samsung Gear VR. In particular, the two experiments focused on isolating the cognitive load cost of receiving instructions for a button-pressing procedural task. The studies employed a self-assessment cognitive load methodology, as well as an additional dual-task cognitive load methodology. The results showed that spatial augmented reality led to increased performance and reduced cognitive load. Additionally, it was discovered that a limited field of view can introduce increased cognitive load requirements. The findings suggest that some of the inherent restrictions of head-mounted displays materialize as increased user cognitive load.
本文介绍了两项认知负荷研究的结果，这些研究比较了三种增强现实显示技术：空间增强现实、光学透视式微软 HoloLens 和视频透视式三星 Gear VR。特别是，这两项实验专注于分离接受按钮按压程序性任务说明的认知负荷成本。这些研究采用了自我评估认知负荷方法，以及额外的双重任务认知负荷方法。结果表明，空间增强现实可提高性能并降低认知负荷。此外，还发现有限的视野会增加认知负荷要求。研究结果表明，头戴式显示器的一些固有限制会导致用户认知负荷增加。
