In this article, we report the differences in eye movement between experts and novices in “Mind Map,” a graphical note-taking method. Using a total of six different mind maps, we examine how subjects' eye movements followed the basic structure of each Mind Map stimulus. Each subject was asked to comprehend the content of the mind maps on a display. By using an eye-tracker built into the display, we were able to obtain both subjects’ gaze information and eye-movements without restraining their natural observing behavior. Our findings indicate that while novices observe the mind map on a branch-to-branch basis, as if they were following the note-taking process itself, experts first browse key information located around the central image of the note, then move onto more de tailed content. That is, while novice Mind Mappers thoroughly scan entire branches attached to a trunk, and then shift their attention to the next trunk, experienced Mind Mappers first browse the trunk, possibly to obtain a general idea of what the mind map is about, then shift their attention to detailed branches. This appears as though they were spontaneously building their own table-of-contents.
