The mobile compute device determines a physical location of a light source relative to the mobile compute device based on the second image and identifies a first and second corneal reflection in an eye of the user captured in the first image. The mobile compute device determines, based on the physical location, a first correspondence between the first corneal reflection and the light source and a second correspondence between the second corneal reflection and an image displayed on a display of the mobile compute device. Further, the mobile compute device performs gaze tracking based on the first correspondence and the second correspondence."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Analysis of ambient light for gaze tracking","description":"Technologies for gaze tracking by ambient light include a mobile compute device to capture a first image of a user of the mobile compute device by a first camera and a second image of a real-world env","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9785234","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.
