Sleep behavior assessment via smartwatch and stigmergic receptive fields

This from Personal and Ubiquitous Computing. Stigmergy is finding ever more practical application.

In this paper, we present an automatic tool for monitoring sleep behavior that uses a commercially available smartwatch, in order to sample heart rate and wrist inertial data, and a novel detection technique based on stigmergic receptive fields (SRFs). The SRF transforms an input time series into a stigmergic trail and provides a (dis-)similarity measure against another signal trail.
