| Summary: | Workplace safety training is the cornerstone of workplace safety and accident prevention. In the case of frequently rotating employees, such as in the laboratories of higher education institutions, where students are required to perform tasks as part of their education, a considerable amount of effort for workplace safety training is demanded from the supervising instructors. Accordingly, the use of self-guided workplace safety training may lead to significant savings in the workload for instructors. In this evaluation study, we investigated to what extent an augmented reality (AR) app is deemed suitable for workplace safety training. The prototypical augmented reality (AR) app is based on an AR platform that performs tracking based on visual Simultaneous Localization and Mapping (vSLAM, Google Tango). The workplace safety training was carried out for two common stations and two devices in a workshop of an environmental engineering laboratory at a higher education institution. A total of 12 participants took part in the mixed-method study. Standardized questionnaires were used to assess usability, cognitive load and the learner prerequisites of motivation and emotion. Qualitative results were collected through subsequent semi-structured interviews. The app was able to achieve good usability, and the values for cognitive load can be classified as conducive to learning, as can the values for the learning prerequisites of motivation and emotion. The interviews provided insights into strengths, but also into potential improvements to the app. The study proved that using vSLAM-based AR apps for workplace safety training is a viable approach. However, for further efforts to establish AR-app-based workplace safety training, these insights need to be ported to a new AR platform, as the platform used has since been discontinued. |
