Ubiquitous computing is fostering an explosion of physical artifacts that are coupled to digital information – so-called Spimes. We introduce a tangible workbench that allows for the placement of hyperlinks within physical models to couple physical artifacts with located interactive digital media. A computer vision system allows users to model three-dimensional objects and environments in real-time using physical materials and to place hyperlinks in specific areas using laser pointer gestures. We present a working system for real-time physical/digital exhibit design, and propose the means for expanding the system to assist Design for the Environment strategies in product design. Author Keywords Spime, Tangible User Interface, Virtual Environments, Gestural Interfaces, Product Design, Interior Design, Exhibit Design, Design for the Environment. ACM Classification Keywords H5.m. Information interfaces and presentation (e.g., HCI): Tangible User Interfaces.
