考虑到人类的空间定位和导航能力，用于支持屏幕外目标定位的可视化不可避免地影响依赖于两个框架的视觉空间处理。到目前为止，它还没有被证明的参考框架，自我中心或离心，有助于最有效的观点指导在头戴式增强现实环境。这可能是合理的，缺乏客观评估的分配注意力和心理工作量的指导方法所要求的。本文提出了一个用户研究调查自我中心和离心的观点指导视觉注意力和心理负荷的影响。在定位任务的同时，参与者必须使用oddball范式完成一个分散注意力的任务。在任务完成期间，测量心率变异性以确定生理应激水平。心理负荷的客观评估是由使用NASA TLX的主观评级补充的。结果表明，以自我为中心的观点指导导致最有效的目标提示方面的定位速度更快，更高的精度和更慢的自我报告的工作量。此外，自我中心的目标提示导致生理压力略有下降，使更快地识别同时发生的事件，虽然视觉注意力似乎是隐蔽的方向。
Considering human capability for spatial orientation and navigation, the visualization used to support the localization of off-screen targets inevitably influences the visual-spatial processing that relies on two frameworks. So far it is not proven which frame of reference, egocentric or exocentric, contributes most to efficient viewpoint guidance in a head-mounted Augmented Reality environment. This could be justified by the lack of objectively assessing the allocation of attention and mental workload demanded by the guidance method. This paper presents a user study investigating the effect of egocentric and exocentric viewpoint guidance on visual attention and mental workload. In parallel to a localization task, participants had to complete a divided attention task using the oddball paradigm. During task fulfilment, the heart rate variability was measured to determine the physiological stress level. The objective assessment of mental workload was supplemented by subjective ratings using the NASA TLX. The results show that egocentric viewpoint guidance leads to most efficient target cueing in terms of faster localization, higher accuracy and slower self-reported workload. In addition, egocentric target cueing causes a slight decrease in physiological stress and enables faster recognition of simultaneous events, although visual attention seemed to be covertly oriented.
