Tangible Augmented Reality

This paper advocates a new metaphor for designing threedimensional Augmented Reality (AR) applications, Tangible Augmented Reality (Tangible AR). Tangible AR interfaces combine the enhanced display possibilities of AR with the intuitive manipulation and interaction of physical objects or Tangible User Interfaces. We define what Tangible AR interfaces are, present some design guidelines and prototype interfaces based on these guidelines. Experiences with these interfaces show that the Tangible AR metaphor supports seamless interaction between the real and virtual worlds, and provides a range of natural interactions that are difficult to find in other AR interfaces.
