A Virtual Reality Approach for Assisting Sustainable Human-Centered Ergonomic Design: The ErgoVR tool

Industry 4.0 is characterized by great potential for innovation impacting the operator's role, increasingly engaged in smart activities of a decision-making nature. In such a working scenario, operators' working conditions can be effectively improved by applying a user-centered collaborative design approach. To this end, we developed a Virtual Reality-based multiplayer tool exploiting low-cost body tracking technology to evaluate ergonomic postural risk. The tool allows evaluating both in real-time and off-line the ergonomic postural risk according to the Rapid Upper Limb Assessment metrics. By applying this approach, a twofold advantage can be achieved. On the one hand, ergonomic experts can have an immersive three-dimensional visualization of postures even in off-line observations. On the other hand, it is possible to evaluate the ergonomics of workstations in the design phase by having the operator work on virtual mock-ups of workstations, thus allowing a sustainable approach to user-centered collaborative design.
