Have you ever framed a photo with your hands? You know, make a rectangle with your hands in front of you as if they were a viewfinder…

Well many of us have and a team of researchers in Japan are taking that concept and have built a working prototype camera, the Ubi-Camera, that will actually snap a photo from just the positioning of your hands.

You zoom in by moving your hands closer to your face. You snap the image by depressing a shutter on the actual lens device attached to your thumb. Check out this cool video from the team at Japan’s Institute of Advanced Media Arts and Sciences.
