A movement trajectory of a user's eye is tracked based on an eye-tracking procedure, so as to calculate reading time of a gazing part of an electronic document when it is detected that sight of an eye leaves the gazing part, or when it is detected that the eye keeps gazing the electronic document and reading of the gazing part is finished. And the reading time is recorded to a storage space corresponding to the gazing part."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for recording reading behavior","description":"A method and an apparatus for recording reading behavior are provided.
