Abstract

ObjectiveWe conducted two experiments to understand the effects of computationally diminishing reality on performance, awareness of the environment, and subjective workload.BackgroundAdvances in extended reality (XR) technologies make it possible to alter or remove auditory and visual distractions from an environment. Though distractions are known to harm performance, there is no work examining the effects of removal via XR.MethodAcross two samples, STEM graduate students and Johnson Space Center employees, the effects of reducing distraction during a novel, demanding assembly task via a form of XR (diminished reality) were compared to a full distraction control condition, studied in a virtual reality (VR) environment. In one condition, participants experienced universal attenuation of distractions. In a second condition, attenuation was context-aware: only nontask objects were made less visible and only unimportant off-task audio was eliminated.ResultsBoth experiments found subjective workload could be lowered via a Diminished reality (DR) aid. The STEM graduate student sample showed a benefit of a DR aid for performance and environment awareness; however, the sample of professionals from Johnson Space Center showed no performance differences with the DR aids. There were mixed results regarding awareness of the location of objects and events outside of the assembly task.ConclusionDR aids can have effects similar to those seen in studies that removed distractions entirely. More work is needed to understand the match between distraction removal design and task.ApplicationThese findings contribute to the development of a class of XR aids: Diminished Reality.

认知辅助设计使用减少现实支持选择性注意力通过减少分心。

目的：我们进行了两个实验，以了解计算递减现实感对性能、环境意识和主观工作量的影响。扩展现实（XR）技术的进步使得改变或消除环境中的听觉和视觉干扰成为可能。虽然外界都知道分心会影响工作表现，但目前还没有研究通过XR检测分心的影响。方法在两个样本中，STEM研究生和约翰逊航天中心的员工，通过XR（减少现实）的形式来减少在一个新颖的、要求苛刻的组装任务中的注意力分散的效果，与在虚拟现实（VR）环境中研究的完全注意力分散控制条件进行比较。在一种情况下，参与者普遍感受到干扰的减弱。在第二种情况下，衰减是上下文感知的：只有非任务对象不那么明显，只有不重要的非任务音频被消除。结果两项实验均发现，虚拟现实辅助可以降低主观工作量。STEM研究生样本显示DR辅助设备在绩效和环境意识方面的好处；然而，来自约翰逊航天中心的专业人员的样本显示，使用DR辅助设备后，他们的表现没有差异。对于组装任务之外的对象和事件位置的感知，结果好坏参半。结论：dr辅助工具的效果与研究中完全消除干扰的效果相似。我们需要做更多的工作来理解分散注意力设计和任务之间的匹配。这些发现有助于开发一类XR辅助工具：减少现实。

期刊介绍： Human Factors: The Journal of the Human Factors and Ergonomics Society publishes peer-reviewed scientific studies in human factors/ergonomics that present theoretical and practical advances concerning the relationship between people and technologies, tools, environments, and systems. Papers published in Human Factors leverage fundamental knowledge of human capabilities and limitations – and the basic understanding of cognitive, physical, behavioral, physiological, social, developmental, affective, and motivational aspects of human performance – to yield design principles; enhance training, selection, and communication; and ultimately improve human-system interfaces and sociotechnical systems that lead to safer and more effective outcomes.
