Abstract

This experiment investigated the effects of target word density (i.e., high, medium, and low) and Web page presentation style (i.e., no graphics, static graphics, and animated graphics) on search time and user preferences. Nine Web pages were developed reflecting all combinations of target word density, determined by the number of targets embedded within a 200-word text display, and presentation style. Sixteen undergraduate students from a Systems Analysis and Design class participated. The task required the selection, using the mouse, of the embedded target words in each of the nine Web pages. A full-factorial within-subjects design was used, and the order of presentation of the nine pages was randomly determined for each student. The results showed a significant effect of target density on search time. Search time on low-density pages was significantly briefer than on high-density pages, an outcome that validated the experimental protocol. No significant effect was found for page presentation style, and the interaction between target density and presentation style was not significant. Self-report data showed that static graphics pages and animated graphics pages were sometimes perceived differently in terms of usability and aesthetics, and both styles were perceived as visually appealing to users.
