Design and Implementation of a Non Contact Back Posture Monitoring System

Abstract

This thesis presents the design and development of a posture monitoring system, using a capacitive touch sensor and a time-of-flight distance sensor integrated with a microcontroller. The system detects user posture based on proximity or near contact and distance measurements, then provides real-time feedback through visual and auditory alerts when incorrect posture is maintained for a specified duration. An embedded hardware prototype model is the outcome of this study, which represents a greater vision of a compact and more powerful system.
