We have explored innovative research such as enhancing public safety, healthcare, and workplace ergonomics through fatigue analysis, VR rehabilitation, and AI posture monitoring systems.
Results
Evaluating Camera Viewpoint Control in Telemanipulation: Performance, Workload, Visual Attention, and Usability
This study evaluates five camera setups in telemanipulation (fixed, autonomous/manual dynamic) for a cube-stacking task. Multi-camera systems improved success but increased cognitive load and visual demand. Autonomous dynamic cameras reduced strain, enhanced efficiency, and usability. Mixed-effects models revealed coverage-effort trade-offs, emphasizing 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 the fatigue among Hong Kong's franchised bus drivers, aiming to enhance road safety and driver well-being. It uses wearable devices, computer vision techniques, and questionnaires to analyze the impact of work schedules and sleep patterns on fatigue. The study identifies 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 providing real-time feedback through vibrations and lights. The system serves as 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 discomfort. Results support VR as a promising tool for post-stroke rehabilitation, warranting further large-scale research.
