SurfaceWare

Abstract

Microsoft Surface is distinguished among commercial multi-touch systems by its ability to interact with tagged objects. In this work, we examine a new class of tagged objects where the tag is dynamic---it changes in response to some sensed variable. As an example, a drinking glass is described which can sense when a refill should be offered. The glass is completely passive, containing no electronic components or moving parts, and works with an unmodified Microsoft Surface.
