Put your pointer fingers and thumbs together so they form a rectangle.

Now go “click!”

You just took a picture.

Can you imagine it? That’s what it will be like to take a picture with the Ubi-Camera, now being developed by a group of researchers at the Institute of Advanced Media Arts and Sciences, a university in Japan.

The Ubi-Camera is a tiny rectangular box that fits over your thumb.

For the viewfinder (the thing you would normally look through on a camera to see what you want to take a picture of) you simply form a rectangle with your fingers and thumbs.

To take a picture, you press down on the box. Click! You’ve taken a photo—without a “camera.”
