Camera 3D positioning mixed reality-based interface to improve worker safety, ergonomics and productivity

This research develops a new mixed reality-based worker interface for industrial camera 3D positioning, which is intuitive and easy to manage, in order to enhance the worker safety, ergonomics and productivity. An experimental prototype to be used in the car body quality control is developed in the paper. The benefits and drawbacks of the proposed interface are discussed along the paper and sustained through several usability tests conducted with users familiar and not-familiar with mixed reality devices. Furthermore, the feasibility of the proposed approach is demonstrated by tests made in an industrial environment with skilled workers from Alfatec Sistemas company. (C) 2020 CIRP.
