Résumé

Production process is progressively shifting away from fully automated towards hybrid alternatives. Technology-assisted manual labor in manufacturing, more specifically low-volume processes, promises increased job productivity and is expected to support the workers. This study aims to gain a better understanding of the impacts on productivity, quality and ergonomics/human factors, when smart glasses are introduced in a hybrid system. 10 recruited participants were asked to do four complex assemblies each with 15 repetitions using manual and air ratchets with and without smart glasses. The data was collected through cameras, an eye-tracker, time measuring, NASA-TLX for task workload and quality control with documented pictures of each finished assembly. Results show that completion time was shorter with the smart glasses and, with assembly repetition, participants skipped reading some instructions. Globally, the weighted and unweighted NASA-TLX were high for the physical and effort indicators. Participants’ individual scores however show important differences. All participants made assembly errors, whether bracket alignment or loose bolts. The tools used (manual and air ratchet) had an impact on quality. This paper presents preliminary results. More refined analysis of this study’s data is needed to better comprehend how to integrate conventional, automated, and intelligent technology like smart glasses.
