Bye Kinect: Hello Gmail Motion!
Kinect is innovative and created a step change in gaming. But that's gaming. Now, Google have again leapfrogged the competition by making motion the way to control not only gaming, but to improve everyday productivity too, in gmail. And no expensive camera is needed. Similar to the technology used in YouTube Symphony experiment (follow experiment link), the new gmail motion only requires a standard web cam!
This blog post, btw, was created with similar technology, with slight movement over the keyboard only.
