Description:


    Recently, spatial augmented reality regained popularity in media arts and in the field of tangible, embedded interaction [Holman and Vertegaal 2008], by using 3D objects as information displays. The advantage of projected graphics is obvious: it allows for updatable appearance of 3D objects without refabrication. However, in many everyday objects such as fashion and shoes, projector technology is not feasible due to power and tracking requirements, and the need for a darkened environment. Users cannot take the objects outside the calibrated projector setup.

    We introduce a novel concept of a stateful projector display that uses bi-stable color changing inks. We augment non-planar and complex painted surfaces by projecting high resolution imagery that persist. Similar to e-ink, graphics last without requiring additional power and are rewritable.
