This study aims at comparing a Google Glass-based instructional application with a printed manual in mobile phone disassembly tasks. Thirty participants (15 males and 15 females) were recruited to perform tasks via three types of instructional methods (Google Glass-based augmented reality, Google Glass-based video, and a printed manual). The objective measures of performance (task completion time, error counts), and the subjective measures (NASA-Task Load Index, system usability scale) were considered. Additionally, visual fatigue was assessed by critical flicker fusion frequency and near point accommodation. According to the findings, although the printed manual method produced better results regarding mental workload and system usability, the augmented reality method improved error reduction and efficiency. Furthermore, the participants indicated that the displayed animations were helpful in locating the exact work-pieces. The augmented reality method is believed to be a potential alternative to printed manuals in mobile disassembly tasks.
本研究旨在比较基于 Google Glass 的教学应用程序与手机拆卸任务中的印刷手册。招募了 30 名参与者（15 名男性和 15 名女性），通过三种教学方法（基于 Google Glass 的增强现实、基于 Google Glass 的视频和印刷手册）完成任务。考虑了客观的绩效指标（任务完成时间、错误计数）和主观的绩效指标（NASA 任务负荷指数、系统可用性量表）。此外，通过临界闪烁融合频率和近点调节来评估视觉疲劳。根据研究结果，虽然印刷手册方法在心理工作量和系统可用性方面产生了更好的结果，但增强现实方法提高了错误减少和效率。此外，参与者表示，显示的动画有助于找到确切的工作部件。增强现实方法有望成为移动拆卸任务中印刷手册的一种替代方法。
