OBJECTIVE: To explore the characteristics of user's visual search and selection through interaction with pull-down menus. METHOD: The visual search time and selection time of interaction were recorded by eye tracking system, when 14 participants were performing the task of pull-down menu selection, with different menu length, type of menu item and position of target item. RESULT: It was found that selection time was influenced jointly by menu length, type of menu item and target location, while visual search time was only influenced by target location. CONCLUSION: The results of this experiment support the hypothesis that the pull-down menu was characteristic of serial, self-terminated and top-down.
