Intelligent Ergonomic Chair with AI-Driven Posture Analysis and Correction with Real-Time Feedback

2026 Moratuwa Engineering Research Conference (MERCon)

This publication presents an intelligent ergonomic chair that reduces musculoskeletal risks from prolonged sitting by combining pressure sensing, deep learning posture recognition, automated pneumatic correction, and generative AI guidance in a unified IoT platform. A 10-channel FSR array and ESP32 capture seated pressure data, while an MLP model classifies eight postures with 99.5% accuracy on unseen participants. Sustained poor posture triggers a closed-loop pneumatic lumbar mechanism to improve spinal alignment automatically. A real-time dashboard integrated with Google Gemini provides personalized ergonomic recommendations. A 30-participant usability study demonstrated an 82.0% reduction in sustained poor posture (p < 0.001).
