Design Recommendations for HMD-based Assembly Training Tasks

In the last few years, head-mounted displays (HMDs) received a growing amount of attention by the scientific community, especially in the industrial domain. Due to its possibility to work hands-free while providing the user with necessary augmented information, HMDs can enhance the quality and efficiency of assembly and maintenance tasks. Offering tailored information requires knowledge about how to design and present augmented reality (AR) content. However, design guidelines especially for assembly training tasks as well as usability evaluations are very limited. In this paper, we want to overcome this limitation by introducing an application as well as 10 design recommendations for HMD-based assembly training tasks. Furthermore, we execute a user study with15 participants using an engine assembly training task to evaluate the software usability and present results from the system usability scale (SUS) questionnaire, the AttrakDiff as well as the NASA task load index (NASA-TLX) questionnaire.
