Extended reality technologies improve collaboration in remote maintenance operations, reducing errors and completion time significantly.
Sintesi
The study explores the use of extended reality (XR) technologies to enhance collaboration during remote maintenance operations. By utilizing mixed reality (MR) and virtual reality (VR) setups, a shared Digital Model of a heat exchanger is used to facilitate tracking and displaying specific information for operators and experts. The research demonstrates substantial improvements in collaborative inspection efficiency, leading to reduced completion times and error frequencies.
The content discusses the impact of Industry 4.0 technologies like Digital Twins (DT) and XR on industrial performance, focusing on maintenance procedures in the Architecture, Engineering, and Construction (AEC) sector. Data from building information models (BIM) is utilized to create BIM-based DTs that centralize equipment data for predictive maintenance. XR devices provide contextual information for remote experts during collaborations, enhancing communication through visual aids like annotations, gaze sharing, gestures, and avatars.
A user study compared the efficiency of XR solutions with standard audio-video collaboration methods. Results showed significant enhancements in completion time and error reduction when using XR technologies. The study involved tasks related to manipulating valves in a heat exchanger system under different conditions: Tablet with audio-video calls versus HMD with MR client interactions.
The findings indicate that XR technologies offer tangible benefits by improving performance efficiency and reducing errors during collaborative maintenance operations remotely.
