Skin is the plane of contact between people and things. Traditionally, the skins of objects are passive and static. They were simply dead outer surfaces. However, recent advances in technology have made them more active and dynamic.
Shade Pixel [video] is an interactive display that uses small depressions in its surface instead of a light source. It can be used as an ambient display for its peripherality; non-luminescent nature and simple appearance. The main difference from other displays is that Shade Pixel is applicable to the surfaces of everyday products or to the environment as an interactive skin.
