Collaborative Augmented Digital Twin: A Novel Open-Source Augmented Reality Solution for Training and Maintenance Processes in the Shipyard of the Future

Large companies use a lot of resources on workshop operator training and industrial machinery maintenance since the lack this practice or its poor implementation increases cost risks operating handling sensitive and/or hazardous machinery. Industrial Augmented Reality (IAR), major technology in Industry 4.0 paradigm that may enhance worker performance, minimize hazards improve manufacturing processes, could be beneficial situation. This paper presents an IAR solution allows for visualizing interacting with digital twin critical system. Specifically, augmented cooler was developed. The proposed system provides dynamic way to perform full-size model actual equipment provide step-by-step guidance so processes can performed more safely efficiently. also several users devices at same time, creating new type collaborative interaction by viewing place state. Performance tests many simultaneous have been conducted, response latency being measured as number connected grows. Furthermore, suggested has thoroughly tested real-world environment.
