Shadow reaching: a new perspective on interaction for large displays

Shoemaker, G., Tang, A., and Booth, K. (2007). Shadow reaching: a new perspective on interaction for large displays. In UIST '07: Proceedings of the 20th annual ACM symposium on User interface software and technology, 53--56.

Abstract

We introduce Shadow Reaching, an interaction technique that makes use of a perspective projection applied to a shadow representation of a user. The technique was designed to facilitate manipulation over large distances and enhance understanding in collaborative settings. We describe three prototype implementations that illustrate the technique, examining the advantages of using shadows as an interaction metaphor to support single users and groups of collaborating users. Using these prototypes as a design probe, we discuss how the three components of the technique (sensing, modeling, and rendering) can be accomplished with real (physical) or computed (virtual) shadows, and the benefits and drawbacks of each approach.
