No clunky wearables? No chest strap on the treadmill? Heart rate and respiration? Monitors everyone in the house simultaneously 24/7 on a cheap rpi? I hope this doesn't take years to come to market because this seems incredibly useful.

Whole-home gesture recognition sounds really cool! Has anyone actually got this running?

IDK what the error rate of gestural recognition with Wifi is. FWIU the market for e.g. the Magic Leap gestural peripheral just wasn't there. That paper says 2013.
