Demonstrating the Electronic Cocktail Napkin: a paper-like interface for early design
    ACM Conference on Human Factors in Computing (CHI ‘96) Conference Companion, pp. 5-6. 1996
    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.
