Abstract
Zooming interfaces hold the promise of helping users navigate through a large information space. This study investigates the effect of animating the motion from one object to another when following hyperlinks. The hypothesis is that smoothly animated motion will improve the user’s performance by providing navigation cues that would help the user maintain a sense of location in the information space. This report describes an experiment that evaluates this premise by measuring task performance time, the total number of hyperlinks followed to perform a task, and the retention of information after task completion.
