Research
We have explored innovative research such as enhancing public safety, healthcare, and workplace ergonomics through fatigue analysis, VR rehabilitation, and AI posture monitoring systems.
Evaluating Camera Viewpoint Control in Telemanipulation: Performance, Workload, Visual Attention, and Usability
This study evaluates five camera setups in telemanipulation (fixed, autonomous, and manual dynamic) for a cube-stacking task. Multi-camera systems improved success rates but increased cognitive load and visual demands. Autonomous dynamic cameras reduced strain, enhanced efficiency, and improved usability. Mixed-effects models revealed coverage-effort trade-offs, emphasizing the importance of adaptive automation for optimizing performance and operator well-being in robotic surgery and remote maintenance.
Effect of Fatigue on Hong Kong’s Franchised Bus Captains
This research studied fatigue among Hong Kong's franchised bus drivers, aiming to enhance road safety and driver well-being. It used wearable devices, computer vision techniques, and questionnaires to analyze the impact of work schedules and sleep patterns on fatigue. The study identified patterns and correlations, leading to recommendations for improved work schedules, rest periods, and fatigue-monitoring systems, ultimately promoting a safer and healthier public transit environment.
Work Posture Monitoring and Feedback Research
This research project developed a cost-effective system to monitor and improve seated work postures, reducing posture-related injuries. It includes a monitoring platform using RGB cameras and AI to classify postures by risk levels based on RULA criteria, and an intelligent vest that provides real-time feedback through vibrations and lights. The system serves as both a personal and professional tool for enhancing workplace health and safety.
Immersive Virtual Reality-based Exercise System for Poststroke Upper Limb Motor Rehabilitation
The study showed that the immersive VR-based exercise system effectively improved upper limb function and quality of life for stroke patients, with significant gains in shoulder abduction AROM. Patients reported positive perceptions, though some faced challenges with VR device handling and experienced discomfort. The results support VR as a promising tool for post-stroke rehabilitation, warranting further large-scale research.
