We are developing tangible imaging systems 1-4 that enable natural interaction with virtual objects. Tangible imaging systems are based on consumer mobile devices that incorporate electronic displays, graphics hardware, accelerometers, gyroscopes, and digital cameras, in laptop or tablet-shaped form-factors. Custom software allows the orientation of a device and the position of the observer to be tracked in real-time. Using this information, realistic images of threedimensional objects with

Tangible imaging systems thus allow virtual objects to be observed and manipulated as naturally as real ones with the added benefit that object properties can be modified under user control. In this paper we describe four tangible imaging systems we have developed: the tangiBook -our first implementation on a laptop computer; tangiView -a more refined implementation on a tablet device; tangiPaint -a tangible digital painting application; and phantoView -an application that takes the tangible imaging concept into stereoscopic 3D.
