You know that scene in Minority Report where all the digital billboards are watching Tom Cruise and serving him custom ads? From 2002, it seemed like something way off in the future but here we are in 2017 and companies like Visage Technologies have some very robust Face Tracking & Analysis software at the ready. Do yourself a favor and check out this tracking demo. It's HTML5 and is able to pinpoint all major points of the face and the conveyed emotions that go along with it. I've got a fairly burly beard at the moment and that didn't seem to slow it down one bit.

The knee jerk reaction is to feel like this is leading to an intrusive future... and maybe it is... but it's undeniably interesting to think about the applications of tech like this, for good or bad. Either way, it's also fun to see a bunch of dots on your noggin and make some silly faces.
