Reviving a Tangible Interface Affording 3D Spatial Interaction
Tangible interfaces offer natural means of human computer interaction and have already been shown to simplify existing computerized applications and offer solutions for tasks that were considered to be "Out of the scope" of human-computer interaction. The authors are currently perusing new applications for 3D geometry defining tangible interfaces. In this paper the attempt to provide the reader with introduction to the underling paradigms and research in this emerging domain. They describe in detail a tangible interface, the Segal Model, created by John Frazer and his colleagues 20 years ago. They detail the technical efforts in reviving this tangible interface and updating its communication and operating techniques.
