Abstract: | Enterprise software pages, routinely used to conduct a variety of business-relevant tasks, must be clear and nonconfusing to experienced end users. A study was conducted to consider the impact of several page design factors (background gradient, font, and font size) on perceived ratings of page clarity, completion time, emotional valence (EV) from video, and several eye-tracking parameters. Twenty professional managers each completed 25 tasks on enterprise web pages designed with specific combinations of these factors. Highly rated pages had Tahoma and Larger fonts, compared to Calibri and Smaller fonts. The Gradient background did not influence ratings but did increase the search area and completion time. Although EV was not a sensitive measure across tasks, it was influenced by font differences in the first few seconds of page presentation. Overall, the use of background gradient was not supported, but both Tahoma and Larger fonts were supported for these enterprise pages. |
