Augmented Reality (AR) systems have been shown to positively affect mental workload and task performance across a broad range of application contexts. Despite the interest in mental workload and the increasing number of studies evaluating AR use, an attempt has yet to be made to identify the relationship between the effects of AR on mental workload and task performance. This paper seeks to address this gap in AR technology literature. With a better understanding how AR affects mental workload and task performance, researchers and developers can design more effective AR systems. 34 articles investigating the effects of the use of AR systems were selected for the review. A positive correlation was found between effects on mental workload and effects on task performance: if the effect on mental workload is positive, then the effects on task performance are more likely to be positive as well, and vice versa. Effectiveness of AR systems were shown to be influenced by the type of AR display device used, relevance and timeliness of content, information presentation, user characteristics and task characteristics. Additionally, the paper addresses the use of the concept of mental workload and limitations in current literature.
增强现实（AR）系统已被证明在广泛的应用场景中对心理负荷和任务绩效有积极影响。尽管人们对心理负荷很感兴趣，且评估AR使用情况的研究数量不断增加，但尚未有人尝试确定AR对心理负荷和任务绩效的影响之间的关系。本文旨在填补AR技术文献中的这一空白。通过更好地理解AR如何影响心理负荷和任务绩效，研究人员和开发人员可以设计出更有效的AR系统。本综述选取了34篇研究AR系统使用效果的文章。研究发现，对心理负荷的影响与对任务绩效的影响之间存在正相关关系：如果对心理负荷的影响是积极的，那么对任务绩效的影响也更有可能是积极的，反之亦然。研究表明，AR系统的有效性受所使用的AR显示设备类型、内容的相关性和及时性、信息呈现方式、用户特征以及任务特征的影响。此外，本文还讨论了心理负荷概念的使用以及当前文献中的局限性。
