Wireless sensor network based wearable smart shirt for ubiquitous health and activity monitoring
Young-Dong Lee,Wan-Young Chung +1 more
TL;DR: The smart shirt which measures electrocardiogram (ECG) and acceleration signals for continuous and real time health monitoring is designed and developed and the adaptive filtering method to cancel artifact noise from conductive fabric electrodes in a shirt is also designed and tested.
Journal ArticleDOI
Driver fatigue and drowsiness monitoring system with embedded electrocardiogram sensor on steering wheel
TL;DR: Real time driver health condition monitoring system with drowsiness alertness was proposed and the driver's health condition such as the normal, fatigued and drowsy states was analysed by evaluating the heart rate variability in the time and frequency domains.
Journal ArticleDOI
Detection of Driver Drowsiness Using Wavelet Analysis of Heart Rate Variability and a Support Vector Machine Classifier
Gang Li,Wan-Young Chung +1 more
TL;DR: The aim of this study is to classify alert and drowsy driving events using the wavelet transform of HRV signals over short time periods and to compare the classification performance of this method with the conventional method that uses fast Fourier transform (FFT)-based features.
Journal ArticleDOI
Driver Alertness Monitoring Using Fusion of Facial Features and Bio-Signals
Boon-Giin Lee,Wan-Young Chung +1 more
TL;DR: The manifold testing of the system demonstrates the practical use of multiple features, particularly with discrete methods, and their fusion enables a more authentic and ample fatigue detection.
Journal ArticleDOI
Smartwatch-Based Wearable EEG System for Driver Drowsiness Detection
TL;DR: A support vector machine-based posterior probabilistic model (SVMPPM) aimed at transforming the drowsiness level to any value of 0~1 instead of discrete labels is proposed, indicating that the combination of the proposed SVMPPM, the EEG headband, and the wrist-worn smart device constitutes an effective, simple, and inexpensive wearable solution for DDD.
