Real-time data analysis and 3D representation for postural assessment in manufacturing processes

Industry 4.0 passes through the concept of smart factories, bringing into the in-dustrial context a new vision of production lines and workflows, which can now be designed considering ergonomics and thus the interaction among operators, machines, and tools, in accordance with human-centered design principles. Virtu-al simulations help in reproducing such interactions and in foreseeing solutions to improve the working conditions before installing tools and equipment. In addi-tion, motion capture techniques have proven capable to guarantee the reproduc-tion of human motion with sufficient accuracy. The present work aims at the de-velopment of an integrated tool for ergonomics risk assessment index calculation, using motion capture in 3D environments. With this purpose, starting from mo-tion capture acquisitions, an engine for postural angle calculation, in accordance with international standards, and a Unity-based application have been specifically designed and validated. The work is part of the IM.PR.ES.S.E.D. (IMmersive PRocESs ergonomicS by wEarable Devices) project.
