Abstract
The Viscous Display explores the exchange of social information through transient public interfaces. Shaped by principles of 'underground public art', the Viscous Display is conceived as a novel mobile communication medium, where messages can be shared in public spaces. Inspired by biological learning systems; the Viscous Display learns sensorial information that form along traces of a participant's touch and maps this information onto a flexible display. Because it is made up of inexpensive materials, the Viscous Display is also a disposable artifact that may be collected in public spaces. It combines multi-modal sensing, learning algorithms, and a pliable silicone display.
