A position of a second center point of the cornea is determined using the first vector and a position of the feature point detected from the second face image. A second vector is determined using the position of the second center point of the cornea and a position of a center point of a pupil. The gaze of the user is tracked by using the second vector. An apparatus for tracking a gaze is also disclosed."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for tracking gaze","description":"A method for tracking a gaze includes determining a position of a first center point of a cornea by using at least two lighting reflection points detected from an eyeball area of a first face image of","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9830512","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
