ABSTRACT
Web sites need fast and effective navigation systems. An eye tracking laboratory study with n = 120 participants was conducted to compare the influence of different navigation designs (vertical versus dynamic menus) and task complexity (simple versus complex navigation tasks) on user performance, navigation strategy, and subjective preference. With vertical menus, users needed less eye fixations, were faster and more successful. We conclude that, firstly, vertical menus fit better to perception and cognition than dynamic menus, where the navigation items are hidden and must be accessed by an additional mouse click. Secondly, navigation systems should be extended with different kinds of navigation items adapted to the complexity of the users’ navigation tasks, because users tend to switch their navigation strategy when confronted with complex tasks.

ABSTRACT
In this study, effectiveness, efficiency and user satisfaction of different menu designs were investigated. 24 graduate students voluntarily participated to the study. The results indicate that horizontal menus are more effective than vertical menus in terms of selecting sub menu items, overall task completion time is not related to menu design, horizontal overlapping menu design is the most effective one in terms of preventing user errors. Lastly, user satisfaction doesn't vary according to menu designs.
