The screen can be continuously switched between these two states so quickly that the change is imperceptible to the human eye. It is then possible to project back the image perceived as stable on the display surface, when the screen is in fact transparent for half the time. Clear periods can be used to project a second different image across the screen over objects on the surface. At the same time, a camera mounted behind the screen can see in the environment. We explore some of the possibilities offered by this type of screen technology, allowing interactions of surface computing to extend beyond the screen.
