Microsoft's motion-sensing keyboard lets you skip the touchscreen
As convenient as touchscreens and air gesture controls can be on a PC, it's not very comfortable to keep raising your hands just to handle basic tasks. You might not have to subject your arms to that kind of strain if Microsoft's experimental Type-Hover-Swipe keyboard ever reaches shelves, though. The peripheral hides a grid of infrared motion sensors between the keys, letting you perform hand gestures in a more natural position. While the technology is very low-resolution (there's just 64 pixels of data), it's both fast and precise enough to recognize more advanced commands. Among other tricks, you can mimic a steering wheel with your hands when playing a racing game.
