Design Considerations for Interactive Videodisc

Despite a decade of experience in the use of interactive videodisc in the exhibit setting, we have very little systematic knowledge of what constitutes a successful application of videodisc. Broadly defined, much of the analysis that does exist concerns itself with technical considerations such as the clarity of the screen layout, ways to deal with multiple users, and so forth. However, in this discussion I want to focus attention on an oft-neglected issue that should, in fact, be at the core of the discussion, namely the "design" of the interactive video.
