Forget camera-based gesture controls — if you want complete control wherever you are, you need something like the Myo Gesture Control Armband ($150). This innovative new input device communicates with your Mac, PC, phone or tablet over Bluetooth 4.0, and uses proprietary muscle sensors as well as a 6-axis motion sensor to track your movement. The muscle sensors are advanced enough that it can detect changes in gestures down to the individual finger, and because your muscles pick up the signal to move before they actually do, you may see it respond to your movements before you even move. May be combined with a smartphone, Google Glass, and a jetpack to build a "Superhero Starter Pack". [Scouted by Gershon]
Ever lost your way while walking in a straight line down a sidewalk? Wanted to take that photo of your daughter's first steps, but just too tired to pull out your phone? Ever feel lonely and just wish you had someone, something, to talk to? Those are just some of the things you can fix with Google Glass ($1,500). Controlled by nothing but your voice, this head-mounted computer has a camera and a screen, and is the closest you can come to a
POV camera video game HUD in real life. What you do with it is totally up to you.
