Head-worn displays (HWDs) have been studied extensively in healthcare and industrial contexts over the past years. In this survey paper, we analyse the use of HWDs that do not occlude the view of the environment in those two domains. In addition, we explore researchers' approaches to the design of HWD applications. Across four databases we found 351 papers that describe HWD applications in healthcare or industrial contexts. All located papers were systematically categorized and a subset of 96 unique and influential papers was selected to be included in this survey paper. The paper offers three main contributions. First, we describe seven distinct groups of HWD use cases. Second, we show that papers seldom report that design principles, previous research, or user input have informed the design of HWD applications. Third, we illustrate similarities and key differences between HWD research in the healthcare and industrial domains and show that research in each domain has considerable relevance for the other. Based on the results of our analysis, we summarize recommendations for the design of HWD applications, and outline promising future research directions.

在过去的几年里，头戴式显示器 (HWD) 在医疗保健和工业环境中得到了广泛的研究。在这篇调查论文中，我们分析了在这两个领域中不遮挡环境视图的 HWD 的使用。此外，我们探索研究人员设计 HWD 应用程序的方法。在四个数据库中，我们找到了 351 篇描述医疗保健或工业环境中 HWD 应用的论文。所有找到的论文都被系统地分类，并选择了 96 篇独特且有影响力的论文作为调查论文的子集。该论文提供了三个主要贡献。首先，我们描述了七组不同的 HWD 用例。其次，我们表明，论文很少报告设计原则、先前的研究或用户输入已经为 HWD 应用程序的设计提供了信息。第三，我们说明了医疗保健和工业领域 HWD 研究之间的相似之处和主要差异，并表明每个领域的研究与另一个领域都有相当大的相关性。根据我们的分析结果，我们总结了对 HWD 应用程序设计的建议，并概述了有希望的未来研究方向。
