Abstract

Computer-Based training (CBT) is a widely used strategy in interactive learning and skills training to provide the trainee with information while in training. Extended Reality (XR) is a set of technologies used in the fourth industrial revolution for this purpose. However, an important XR limitation is the cognitive overload in trainees due to continuous changes in attention. The effects of the changes in attention on cognitive load have been studied in environments such as printed material and desktop PC's. However, such effects are not yet fully known on XR platforms. This study's aim was to identify strategies to reduce the changes in attention in instructional/educational materials, which use extended reality to present information to trainees. The presented information can guide the use of combined strategies to reduce the cognitive overload generated by XR display platforms. Therefore, an extensive literature review was carried out. From a set of 1946 articles, 53 studies were selected. The selected studies evaluated the cognitive load in instructional materials that used XR as a visualization platform. The results showed three strategy groups: those associated with the spatial integration of information, those associated with the use of visual features and those associated with the content segmentation. Effects of this strategies in the user performance and user cognitive load are discussed.

摘要

基于计算机的培训(CBT)是交互式学习和技能培训中广泛使用的一种策略,用于在培训过程中为学员提供信息。扩展现实(XR)是第四次工业革命中为此目的而使用的一组技术。然而,XR的一个重要局限性是由于注意力的不断变化,学员会出现认知过载。在印刷材料和台式电脑等环境中,已经研究了注意力变化对认知负荷的影响。然而,在XR平台上,这种影响尚未完全明确。本研究的目的是确定减少教学/教育材料中注意力变化的策略,这些材料使用扩展现实向学员呈现信息。所呈现的信息可以指导使用组合策略来减少XR显示平台产生的认知过载。因此,进行了广泛的文献综述。从1946篇文章中,选出了53项研究。所选研究评估了将XR用作可视化平台的教学材料中的认知负荷。结果显示了三个策略组:与信息空间整合相关的策略、与视觉特征使用相关的策略以及与内容分割相关的策略。讨论了这些策略对用户表现和用户认知负荷的影响。
