Mobile end-user devices, such as the new version of the “Apple Watch”, have a drawback: their small screen size makes them difficult to use. Computer scientists have now developed an alternative, which they call “DeformWear”. A tiny switch, no larger than the head of a pin, is built into a ring for example, and worn on the body. It can be moved in all directions, pressed, pinched, and pushed toward the right, left, up, and down.
