Sleep behavior assessment via smartwatch and stigmergic receptive fields

I mentioned this paper when it first came out a few years back. As we’ve put it before, stigmergic behaviour can be found from ants to economies. As someone with an overlapping interest in both stigmergy and sleep disorder, this technology seems very promising since it’s infinitely less intrusive than the clumsy and high-priced devices that are standardly employed to monitor sleep.
