MrSeb writes "It seems Minority Report-style computer interfaces might arrive a whole lot sooner than we expected: A new USB device, called The Leap, creates an 8-cubic-feet bubble of 'interaction space,' which detects your hand gestures down to an accuracy of 0.01 millimeters — about 200 times more accurate than 'existing touch-free products and technologies,' such as your smartphone's touchscreen or Microsoft Kinect. Unfortunately Leap Motion (the company behind the Leap) is being very tight-lipped about the technology being used, but it's probably some kind of infrared LIDAR (radar, but using light), or perhaps a high-resolution version of Kinect (which only uses a 640x480 camera). It's available to pre-order for $70 — and developers can register for a free device + SDK."
Today's scientific question is: What in the world is electricity?
And where does it go after it leaves the toaster?
