The method includes: capturing a line-of-sight direction; determining a change of an angle between a line of sight and a screen, and/or a change of a distance between a user and the screen according to the line-of-sight direction; and performing, according to the change of the angle and/or the change of the distance, a corresponding operation on content displayed on the screen. Corresponding to the foregoing method, the foregoing apparatus includes: a line-of-sight tracking unit, a processing unit, and an executing unit. In the present invention, an action of a user can be determined without depending on gravity sensing, and a corresponding operation can be performed on content displayed on a screen."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Human-machine interaction method and apparatus","description":"Embodiments of the present invention disclose a human-machine interaction method and apparatus.
