Improving educational computer exhibits at radiologic meetings by modifying computer environment: results of an observational study.

An observational study of educational computer exhibits (ECEs) at the 86th Scientific Assembly and Annual Meeting of the Radiological Society of North America in 2000 was performed to determine the frequency with which the ECEs were in working order. At any given time, an average of 10% of the 71 exhibits were found to be inoperable, and, although some exhibits were functioning 100% of the time, others were not functioning up to 55% of the time. These observations underscore the importance of careful design when creating a computer-based exhibit for a meeting. Downtime of ECEs at meetings is the result of both intentional and unintentional user actions. Given that traditional poster presentations are "working" 100% of the time, modifications made to the environment of an exhibit computer to reduce downtime would be beneficial. Several relatively easy computer configuration steps can be taken that will likely improve the amount of time that an exhibit is functional. Electronic exhibits allow a more interactive experience for users and, with some assistance, will continue to be an effective educational tool.
