Leap motion-control

I’m really looking forward to more “XBOX kinect like” products coming our way in the next few years.

I’m also curious about interactions with no sensory feedback. I learnt to type on a physical (desktop/mobile) keyboard and it always felt very easy and comfortable. When I moved to typing on a sheet of glass, it felt a bit weird but I quickly got used to it. Now, it feels almost as easy as a physical keyboard. Would we learn typing on air with similar ease?
