Tangibly Simple, Architecturally Complex: Evaluating a Tangible Presentation Aid

Abstract

In this paper, we describe an evaluation of the Palette, a presentation tool that was reported at CHI ’99. The Palette allows presenters to quickly access digital presentations using physical cards that have unique barcodes printed on them. The Palette has been in use in our lab for over three years, and has been released as a product in Japan. Our evaluation consists of an analysis of usage logs, an expert walkthrough review, and observations and interviews with users, non-users and the system administrator. The findings reveal benefits and drawbacks of the technology, and offers design ideas for further work on tangible tools of this kind.
