If you're using a standard mouse or a trackpad, there's a good chance you've got a finger or two going to waste, and really, what's the point of having all of those digits if you're not going to put them to work? Japan's Double Research & Development Co. is showing off the Amenbo, a new input device that doesn't waste a single finger. Each gets its own pad with a mouse sensor, all connected to a single base with a flexible material that allows for movement. The device can detect pressure and motion of the fingers, and is ideal for interfacing with things like 3D CAD data, which usually requires two hands. It's also apparently great for use with robot hands and getting androids to flash the metal sign. Video of the device after the break.
