Розумна система моніторингу робочого стану користувача на основі комп'ютерного зору (anti-fatigue system)

Abstract

The paper presents the design and implementation of an intelligent realtime user fatigue monitoring system based on computer vision. The system uses a standard webcam and an ultrasonic distance sensor to track two key ergonomic parameters: eye blink frequency as an indicator of cognitive fatigue, and the distance between the user and the monitor as a posture quality metric. When critical thresholds are exceeded – indicating drowsiness or incorrect posture – the system triggers a visual alert by changing the color of a desk LED strip connected via a microcontroller. The proposed solution is low-cost, non-intrusive, and suitable for integration into home or office workstations to reduce the risk of occupational fatigue-related health disorders
