 I'm Ellis Hamburger with The Verge. At CES 2014, everybody seems to be trying to find the best way to track your body, your hands and even your eyeballs. But up to now this technology has been pretty useless aside from the Xbox Kinect. But I saw some pretty cool stuff today that might just make it into your next smartphone or tablet. First I checked out Tobii, an insanely accurate eye tracking technology that pinpoints where you're looking down to the centimeter. In eye asteroids, anywhere you look becomes victim to a missile strike. I felt like God summoning hellfire with every glance. Tobii also lets you zoom in on maps using your eyes and even lets you change the radio station in the car without taking your eyes off the road. But that feature isn't quite ready for production yet. I also checked out Soft Kinetic, a crazy Oculus Rift Xbox Kinect hybrid setup that lets you view a virtual world in 3D but also manipulate objects inside it. You can't feel the blocks you're stacking of course, but I felt one step closer to being inside a holodeck for the first time. Cameras and sensors are battery killers though, so Elliptic Labs developed ultrasonic technology so your phone and tablet can pinpoint your location using only sound waves. You can gesture to switch songs, scroll through articles, whack mobsters and answer phone calls, even if your hand is inches away from your phone or tablet. Most gesture based interfaces are still a pipe dream, but Intel hopes to change that with Reelsense. A new Kinect-like sensor that it plans to ship in tons of computers this year. The company's initial demos let you tug on psychedelic harp strings, play virtual piano and screw around with a digital electric guitar. We haven't quite achieved the brilliant gestural interfaces Tom Cruise manipulates in Minority Report, but we're getting closer. After slicing up melons in Fruit Ninja with only my eyes, I knew these guys were on to something. So make sure to keep your eyes and hands inside the ride.
