Abstract:

This study reports on the usability test of three weight loss websites. In addition, eye tracking patterns were observed for initial exposure to each site home page. Results indicate that participants were able to search the Atkins diet site more efficiently than the Jenny Craig website or Weight Watchers website and preferred this site overall. Analysis of eye-tracking data suggests users first fixate on graphics and large text even when looking for specific information. Interface issues contributing to overall satisfaction and preference are discussed.
