The LG Rolly keyboard will get launched this September in the US. and later to rest of the world, official demonstration video shared below.

From cellphones to cars, glasses to watches - everything is getting smarter so why not a "Smart-Keyboard"? Well we do have one now - The research division at Microsoft has came up with something innovative which should make those tiring hands travel to grab mouse a thing of past, the motion-sensing keyboard lets users perform gesture based tasks like scrolling, zooming etc. by hovering over the keyboard just like a touchscreen. The Type-Hover-Swipe Keyboard utilizes a grid of hidden infrared motion sensors beneath keyboard keys, letting users perform hand gestures in a more natural position. The technology is fast and precise enough to recognize advanced commands like mimicking a steering wheel with your hands when playing a racing game as also demonstrated in the video shared below.
