This paper presents a summary of usability work done at the Usability Laboratory at University of Nebraska in the last few years. The main objective of the first study was to compare the efficiency and effectiveness between user testing and heuristic analysis in evaluating four different commercial websites. The results showed that both user testing and heuristic analysis addressed very different usability problems and both methods are equally efficient and effective. In the second study, the primary purpose was to compare the performance between remote usability testing and traditional usability testing. The results indicate that remote usability testing is no different from traditional usability testing. The third study attempted to look at cultural differences in web usability. The results indicated that cultural dimensions have significant effects on user's web preferences. The primary objective of final study was to determine if user's surfing behavior could be predicted through their cognitive style. Results show that cognitive span scores are not strong enough to form association rule with individual difference clusters of web surfing behavior. The results are discussed with respect to all perspectives of Web.
