The screen can be continuously toggled between these two states so quickly that the switching is imperceptible to the human eye. It is then possible to rear-project what is perceived as a stable image onto the display surface, when the screen is in fact transparent for half the time. The clear periods may be used to project a second, different image through the display onto objects held above the surface. At the same time, a camera mounted behind the screen can see out into the en-vironment. We explore some of the possibilities this type of screen technology affords, allowing surface computing interactions to extend \u201ebeyond the display\u201f. We present a single self-contained system that combines these off-screen interactions with more typical multi-touch and tangible surface interactions. We describe the technical challenges in realizing our system, with the aim of allowing others to experiment with these new forms of interactive surfaces.<\/p>\n<\/div>\n<p><!-- .asset-content --><\/p>\n","protected":false},"excerpt":{"rendered":"<p>We introduce a new type of interactive surface technology based on a switchable projection screen which can be made diffuse or clear under electronic control.
