Virtual reality in ergonomics by wearable devices: experiences from the automotive sector

Abstract

PurposePreventive ergonomics is essential to protecting the health and safety of workers as is recognizing human variability. The purpose of this paper is to describe a Unity-based application designed for three-dimensional postural analysis and visualizations using motion capture data. Integration with virtual reality (VR) technologies allows the user to be immersed in the simulated working environment without the need for a physical prototype. The proposed application aims to facilitate the application of ergonomic principles in workplace design and assessment for a proactive, participatory and inclusive approach to worker well-being.Design/methodology/approachThe authors developed an application that leverages motion capturing techniques and VR technologies and aims to support the analysts in the ergonomic assessment of physical prototypes as well as future workplaces. An innovative postural prediction module helps the analyst understanding what postures different users are likely to assume in the interaction with the workplace from a single data record.FindingsThe functionalities of the proposed application are illustrated on some case studies, presenting how different information is made available and can support workplace analysts and designers in an industrial context.Originality/valueThis paper provides insights into the experience and research carried out by an automotive company in the application of wearable sensors and VR to support a proactive and participatory approach to workplace ergonomics.
