This paper describes ways that computers currently are used (and misused) in museums as interpretive support devices and the potential role computers can play in museums to improve the quality of visitor attention, involvement, and learning. Where and when computers can productively serve interpretive functions are discussed. However, it is pointed out that computers are not always cost-effective. Printed text with imbedded questions, interactive labels, and other nonelectronic methods often serve these functions as well or better than computers. References for follow-up study are included.
