我们探索开发一种实验性增强现实应用程序，为在现场执行维护和维修任务的专业机械师带来好处。我们开发了一个原型，支持军事机械师在装甲车炮塔内执行日常维护任务，并通过用户研究对其进行了评估。我们的原型使用跟踪式头戴式显示器，通过文本、标签、箭头和动画序列增强机械师的自然视野，旨在促进任务理解、定位和执行。一项受试者内对照用户研究检查了专业军事机械师使用我们的系统在现场条件下完成 18 项常见任务。这些任务包括安装和拆卸紧固件、指示灯以及连接电缆，所有这些都在装甲运兵车炮塔的狭窄内部进行。增强现实条件根据两个基线条件进行了测试：相同的头戴式显示器提供未跟踪的文本和图形，以及代表当前实践中使用的基于笔记本电脑的文档的改进版本的固定平板显示器。增强现实条件允许机械师比使用任一基线更快地定位任务，并且在某些情况下，导致整体头部运动减少。一项定性调查显示，机械师发现增强现实条件直观且满足测试的任务序列。
We explore the development of an experimental augmented reality application that provides benefits to professional mechanics performing maintenance and repair tasks in a field setting. We developed a prototype that supports military mechanics conducting routine maintenance tasks inside an armored vehicle turret, and evaluated it with a user study. Our prototype uses a tracked headworn display to augment a mechanic's natural view with text, labels, arrows, and animated sequences designed to facilitate task comprehension, localization, and execution. A within-subject controlled user study examined professional military mechanics using our system to complete 18 common tasks under field conditions. These tasks included installing and removing fasteners and indicator lights, and connecting cables, all within the cramped interior of an armored personnel carrier turret. An augmented reality condition was tested against two baseline conditions: the same headworn display providing untracked text and graphics and a fixed flat panel display representing an improved version of the laptop-based documentation currently employed in practice. The augmented reality condition allowed mechanics to locate tasks more quickly than when using either baseline, and in some instances, resulted in less overall head movement. A qualitative survey showed that mechanics found the augmented reality condition intuitive and satisfying for the tested sequence of tasks.
