Abstract: This research examines the effects of network delays, document type, and various user characteristics on the perceived usability of distributed documents on the Internet. Six experimental conditions were analyzed: text only documents and documents including text and graphics at three levels of delay. Usability was assessed by analyzing responses to questions about ease of locating information, information organization, information quality, and navigation problems. The results showed significant interactions of network delay and document type on subjects' perceptions of quality, organization, navigation, and several additional factors that are important to organizations providing information on the Internet. Both the number of hours subjects reported spending using the Internet and subjects' self-reported command of the English language were significantly correlated with perceptions of various aspects of the Internet sites examined. While our results indicate that Internet users may prefer highly graphical Web sites, it appears that they are unwilling to tolerate substantial delays, preferring plain text documents as delays increase. Suggestions for future research are provided.
