Abstract

We describe a method to classify online sleep/wake states of humans based on cardiorespiratory signals for wearable applications. The method is designed to be embedded in a portable microcontroller device and to cope with the resulting tight power and weight restrictions. The method uses a Fast Fourier Transform for feature extraction and an adaptive feed-forward artificial neural network as a classifier. Results show that when the network is trained on a single user, it can correctly classify on average 95.4% of unseen data from the same user. The accuracy of the method in multi-user conditions is lower, but still comparable to actigraphy methods.
