For each time instance, a position of a center of corneal curvature is estimated using an image captured at that time instance, a position of a pupil center is estimated using an image captured at that time instance, and a line is determined through the estimated corneal curvature center position and the estimated pupil center position. A first estimated position of a center of the eye is computed based on the lines determined for time instances in a first time period. A second estimated position of the center of the eye is computed based on the lines determined for time instances in a second time period. Relocation of the head-mounted device relative to a user's head is detected based on the first and second estimated positions of the eye center."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Detecting relocation of a head-mounted device","description":"Images of an eye are captured at respective time instances by a camera of a head-mounted device.
