Demonstrating the electronic cocktail napkin: a paper-like interface for early design

Abstract

We demonstrate the Electronic Cocktail Napkin, a pen based interface for conceptual design. The project goal is to support design by recognizing, interpreting, and managing drawings, and to serve as an interface for knowledge-based critiquing, simulation, and information retrieval. We demonstrate the Napkin’s facilities for end-user programmable recognition and interpretation, drawing management, and multi-user collaboration. We show applications of the Napkin: (1) indexing visual databases and (2) a front end to a local area network design program.
