Claim:
1. A method for recording reading behaviour, comprising: performing a correction procedure before an eye tracking procedure is executed, wherein the correction procedure comprises sequentially receiving a plurality of correction images, obtaining a reference correction parameter according to two bright spot positions in an eye area of each of the correction images, and generating a coordinate transformation matrix according to the correction images; displaying an electronic document on a display unit, wherein the electronic document comprises a plurality of parts; capturing an image sequence of a user through an image capturing unit; executing the eye-tracking procedure on the image sequence to track a movement trajectory of an eye of the user, wherein the step of tracking the movement trajectory of the eye of the user comprises: detecting whether a sight of the eye leaves a gazing part when it is detected that the eye gazes the gazing part of the parts; calculating a reading time of the gazing part when it is detected that the sight of the eye leaves the gazing part, wherein the reading time is a time required for the sight moving from a position where the sight starts to gaze the gazing part to a position where the sight leaves the gazing part; calculating the reading time of the gazing part when it is detected that the eye keeps gazing the electronic document and reading of the gazing part is finished; and recording the reading time to a storage space corresponding to the gazing part.
