A Mixed Reality system for the ergonomic assessment of industrial workstations

The use of modeling and ergonomic analysis software is a widespread practice in the industrial sector to effectively improve the operator's well-being and operating comfort within the workplace. In this context, the paper proposes a Mixed Reality system for the ergonomic assessment of industrial workstations. Specifically, the proposed system integrates motion capture tools, a head-mounted display device, and ergonomic analysis software to simulate and analyse the operations to be carried out within a virtual workplace where some physical components, with which the operator interact, are prototyped through 3D printing technology in order to make the simulation as realistic as possible. The proposed Mixed Reality system in fact increases the realism of the simulation and improves the effectiveness of the ergonomics analysis thanks to the haptic feedback that the user perceives when manipulating the physical objects.
