Soli is supposedly very accurate for minute movements and is very small and low-powered allowing it to be embedded in a phone, but this kind of tech has existed for a while. The Leap Motion comes in a really small, embeddable package and works over USB and can track hand movements quite accurately. It's been around for 10 years and was recently acquired by a haptics company. It's never managed to go mainstream or find any real applications outside of niche gaming.

Application #1: Personalized real world interactions, aka 24/7 tracking of real world behavior, putting online tracking to shame. Motion detection is one of those technologies where malicious use outweighs positive use by such a large margin that it deserves an outright ban.

Google is always afraid that someone else would overtake them as the #1 global aggregator of user behavior. They always acted swiftly to be on the forefront of new user tracking technologies, with more or less success. From Analytics to Doubleclick to Android to Maps To Plus. Sometimes they even tell themselves they are the good guys. I just wish they'd sometime realize the proper good guy behavior is to prevent the genie being released out of the bottle, not rush to be the ones releasing / acquiring the first / largest one.

Yesterday I bought a six-pack without touching anything besides (regrettably) the door handle of the cooler and the six-pack itself. Paid by waving my Apple Watch over the POS machine.

It occurs to me that I like the model of carrying my own universal physical interface around with me more than I like sharing a domain- and location-specific one with other people.
