Abstract: Eye-movement is an external manifestation of human psychology and cognitive status.Most previous research focus on how eye-movementis affected by the outside information representations or users' inside states,the interaction effects of appeals of Web information to users' tasks andits impacts to users' eye-movement patterns were seldomly studied.Eye-tracking technology was applied to investigate how the appeals of Web information interact to users' tasks and impacts on eye-movement patterns;emotional appeal and rational appeal were adopted to describe information,and participants were assigned preference and matching tasks in the experiment.The results showed that there were different eye-movement patterns between participants on preference task and on matching task;meanwhile,these differences were impacted by the appeals of the information being watched.The results suggest that,participants' eye-movement patterns are not only restricted tothe inside tasks,but also affected by outside information appeal strategies.Onthe premise of fully considering this interaction effect,it is reasonable to utilize eye-movement data for user classification.

Key words: appeal strategies, users&apos, tasks, eye-movement pattern, user classification
