Master’s Thesis Defense at the College of Computer Science and Mathematics – Department of Computer Science for the student (Mohammed Nabeel Islam Hamed).

It was discussed in the Discussion Hall at the College of Computer Science and Mathematics, University of Mosul, on Thursday, 3 / 9 / 2026.

Master’s Thesis entitled:   ” Real-Time Augmented Reality Sustainable Maintenance Support for Industrial Equipment “   By the student   ” Mohammed Nabeel Islam Hamed “     Supervised by:    Prof. Dr. Dhuha Basheer Abdullah Albazaz and Asst. Prof. Dr. Zeena Nabil Jamil

The thesis addressed the design and development of a fully offline, multimodal augmented reality system that guides non-technical operators in real time through complex mechanical maintenance in high-noise industrial environments, in line with Industry 5.0 and sustainability principles.

The study discussed the challenges of conventional industrial maintenance: the cognitive load of interpreting two-dimensional diagrams, relating them to the actual equipment and tracking the procedural sequence; the operator’s hands being occupied; voice-control accuracy degrading in noise; and existing systems’ reliance on connectivity.

The thesis aimed to build an integrated framework combining markerless recognition via Vuforia Model Target, a Level 1 interactive digital model with an exploded 3D view, and offline voice control through Vosk supported by a novel Sound Pressure Level adaptation algorithm sustaining usable accuracy across 50-90 dB, validated through a controlled between-subjects experiment with twenty non-technical participants.

This thesis contributes to the following Sustainable Development Goals: –

1. Goal (9): Industry, Innovation and Infrastructure, through developing an innovative maintenance-support framework that runs on commodity hardware without specialised infrastructure.
2. Goal (12): Responsible Consumption and Production, through a 51.4% reduction in execution errors and the consequent reduction in material waste from damaged components.
3. Goal (8): Decent Work and Economic Growth, through a 55% reduction in operator cognitive workload and a 30.11% reduction in task completion time.
