[A study on visual search and selection of pull-down menu].
OBJECTIVE
To explore the characteristics of user's visual search and selection through interaction with pull-down menus.


METHODS
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.


RESULTS
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.


CONCLUSIONS
The results of this experiment support the hypothesis that the pull-down menu was characteristic of serial, self-terminated and top-down.
