This former highly experimental wearable tech is becoming more mainstream — but not without controversy. Google Glass, the computer for your face, is trying to make mobile computing hands-free. A simple utter of "OK Glass" will turn the smart eyewear on, and a tap will allow you to scroll through headlines, get directions, and take photos through a tiny screen above your eye.
These days, it's not so much novel as it is a debate starter for issues of personal privacy (Is that thing on?! Are you recording me right now?) and the pervasiveness of tech in our everyday lives. It is, however, the farthest any non-wristbound wearable tech has gone in terms of recognition.
Crazy scale: 4 (Won't wear it till it's cute. Listening, Warby Parker?)
