When learning a motor skill it is helpful to get corrective feedback from an instructor. This will support the learner to execute the movement correctly. With modern technology, it is possible to provide this feedback via mixed reality. In most cases, this involves visual cues to help the user understand the corrective feedback. We analyzed recent research approaches utilizing visual cues for feedback in mixed reality. The scope of this article is visual feedback for motor skill learning, which involves physical therapy, exercise, rehabilitation etc. While some of the surveyed literature discusses therapeutic effects of the training, this article focuses on visualization techniques. We categorized the literature from a visualization standpoint, including visual cues, technology and characteristics of the feedback. This provided insights into how visual feedback in mixed reality is applied in the literature and how different aspects of the feedback are related. The insights obtained can help to better adjust future feedback systems to the target group and their needs. This article also provides a deeper understanding of the characteristics of the visual cues in general and promotes future, more detailed research on this topic.
在学习运动技能时，从教练那里获得纠正反馈是很有帮助的。这将支持学习者正确执行动作。随着现代技术的发展，通过混合现实提供这种反馈成为可能。在大多数情况下，这涉及到视觉提示，以帮助用户理解纠正反馈。我们分析了最近利用混合现实中的视觉提示进行反馈的研究方法。本文的范围是运动技能学习的视觉反馈，涉及物理治疗、运动、康复等。虽然一些调查文献讨论了训练的治疗效果，但本文侧重于可视化技术。我们从可视化的角度对文献进行了分类，包括视觉提示、技术和反馈的特征。这使我们深入了解了混合现实中的视觉反馈在文献中的应用方式，以及反馈的不同方面是如何相关的。获得的见解有助于更好地根据目标群体及其需求调整未来的反馈系统。本文还深入了解了视觉提示的特征，并促进了该主题的未来更详细的研究。
