An MR Remote Collaborative Platform Based on 3D CAD Models for Training in Industry

In this paper, we describe a new Mixed Reality (MR) remote collaborative platform making use of 3D CAD models for training in the manufacturing industry. It enables a remote expert in Virtual Reality (VR) to train a local worker in a physical assembly task. For the local site, we use Spatial Augmented Reality (SAR) to enable the local worker see virtual cues without wearing any AR devices, leaving their user hands free to easily manipulate the physical parts. For the remote expert, we construct a 3D virtual environment using virtual replicas of the physical parts. We also report on the results of a usability study of the prototype.
