Design and validation of a low-cost vehicle driver monitoring device

Abstract

This paper presents the design and experimental validation of a novel low-cost, wearable device for continuous monitoring of the motion and physiological state of vehicle drivers. The system strategically integrates Inertial Measurement Units (IMUs) on the driver’s head, neck, and torso to accurately capture body dynamics while driving. It also incorporates physiological sensors to capture electrocardiography (ECG) and body temperature signals, providing objective indicators of the driver’s physical and emotional state. The device’s architecture enables real-time data processing, which is essential for early detection of risky behaviors such as distracted or aggressive driving. Validation of the device was conducted through an experimental protocol in a controlled urban driving environment, evaluating common maneuvers such as straight-line driving, braking, roundabouts, and lane changes. The results obtained demonstrate the feasibility of the device to characterize significant changes in posture and physiological parameters, demonstrating its potential application as a low-cost tool for driver monitoring in Advanced Driver Assistance Systems (ADAS), accident prevention campaigns, and epidemiological studies of driving behavior.
