Designing a Virtual Reality Training Apprenticeship for Cold Spray Advanced Manufacturing

TL;DR

A VR Training Apprenticeship (VRTA) tailored for cold spray is presented, carefully designed to teach novices step-by-step this particular advanced manufacturing process, to assess its effectiveness and the challenges of considering VR training for advanced manufacturing.

Abstract

Apprenticeship and training programs in advanced manufacturing frequently encounter safety and accessibility concerns due to using heavy machinery. Virtual Reality (VR) training addresses such constraints while maintaining the spatial and procedural learning requirements of such training. However, designing effective VR training is challenging because advanced manufacturing processes are complex and require experts to train novices for a long time. This paper presents a VR Training Apprenticeship (VRTA) tailored for cold spray, which we carefully designed to teach novices step-by-step this particular advanced manufacturing process. To assess its effectiveness, we conducted an exploratory study ($n = 22$). We evaluated user experience (UX) measures in the form of quantitative scales, users' qualitative insights, and task performance with real-world machinery after the VR training. We discuss how the VRTA design contributed to the effectiveness and the challenges of considering VR training for advanced manufacturing.
