Abstract
My study compares local and real-time usability testing with remote and non-real-time testing of a Web site. Both local and remote tests use a Web-based usability testing but the former tests allow local and reat-time observation, the latter tests allow users to participate from their normal work locations using their normal, unmodified browser. Results indicate that both the local and remote tests capture similar information about usability. The graph’s shape of success rate, the percentage of task that users complete correctly, is similar. That of the time each task requires is also similar. The success rate is inversely proportional to the required time in some degree but the relation depends on the task.
