An eye movement data based online user state recognition method and device, the method comprising the following steps: gathering eye movement data when an online user watches a webpage, and pre-processing the eye movement data to acquire the pre-processed eye movement data (S1); performing feature extraction on the pre-processed eye movement data to acquire a plurality of eye movement feature parameters (S2); inputting a plurality of eye movement feature parameters of the online user to a preset state classifier to compare so as to recognize the current working state of the online user as a searching state or a browsing state (S3). The present invention recognizes two working states of online user, searching and browsing, and adopts an active sensing technology to extract two eye movement features as well as a classification method based on a support vector machine, and has a fast learning speed, a high classification accuracy, and a high recognition efficiency. |
