4. Leap Motion

Multi-touch desktop is a (miserably) failed product due to the fact that hands could get very tired with prolonged use, but Leap Motion wants to challenge this dark area again with a more advanced idea. It lets you control the desktop with fingers, but without touching the screen.

It’s not your typical motion sensor, as Leap Motion allows you to scroll the web page, zoom in the map and photos, sign documentss and even play a first person shooter game with only hand and finger movements. The smooth reaction is the most crucial key point here. More importantly, you can own this future with just $70, a price of a premium PS3 game title!
If this device could completely work with Oculus Rift to simulate a real-time gaming experience, gaming is going to get a major make-over.
