UWB-PostureGuard: A Privacy-Preserving RF Sensing System for Continuous Ergonomic Sitting Posture Monitoring

UWB-PostureGuard is an ergonomic posture monitoring technology that continuously detects sitting posture without cameras or wearable devices, while preserving user privacy. The technology is designed for real-time use in everyday desk and seated work environments, providing posture awareness and enabling timely feedback when sustained or potentially harmful sitting positions occur. Because posture monitoring is achieved without video capture, the system supports privacy-preserving deployment in offices, education settings, and care environments where camera-based monitoring may be unacceptable. The contactless approach also avoids the comfort and compliance challenges associated with wearable posture trackers, supporting consistent long-term use.

Background: 
Prolonged sitting with poor posture is a critical ergonomic health problem that can contribute to musculoskeletal discomfort and strain, especially for individuals who spend long periods at desks for work or study. Current posture monitoring solutions typically use camera-based systems or wearable sensors. Camera-based solutions can raise privacy concerns and may be affected by lighting, occlusion, and environmental clutter while wearable solutions can be uncomfortable, require sustained user compliance, and may not be practical for continuous daily monitoring. UWB-PostureGuard addresses these limitations by enabling posture monitoring without cameras and on-body devices. This positioning improves deployability in privacy-sensitive environments and supports more practical, continuous monitoring under typical indoor conditions.

Applications: 

• Workplace ergonomics and occupational health 
• Education environments (universities, libraries, computer labs)
• Healthcare and rehabilitation monitoring (clinics, assisted living, long-term care)
• Digital health and preventive wellness programs
• Ergonomics-enabled smart workspace products and platforms 

Advantages: 

• Privacy-preserving monitoring without camera-based imaging
• Contactless operation without wearables, improving comfort and long-term usability
• Continuous, real-time posture monitoring suitable for extended sitting periods
• Reduced sensitivity to lighting conditions relative to vision-based approaches
• Improved practicality in everyday environments where occlusion and clutter are common
• Supports scalable deployment for organizational ergonomics programs and routine monitoring
