Authors may submit video papers on the same topics as traditional papers. This submission category provides a unique opportunity for many new kinds of submissions. For example, processes and techniques can be shown directly.
Empirical studies can show how the experiment was really run.
Long-term studies can show how people change their usage patterns over time. Descriptions of systems can show how users solve problems. Video papers will be published in the CHI 99 Video Proceedings, which will be distributed to all conference attendees and available for purchase from ACM after the conference. They are accompanied by a four-page textual paper in the CHI 99 Conference Proceedings. Thus, video papers provide the same exposure and long-term access as traditional textual papers.
