A head movement estimator estimates the motion of the head of the user based on a relative position of the reflected light of the second light source with respect to the reflected light of the first light source in the video acquired by the video acquirer."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Video analysis device, video analysis method, and point-of-gaze display system","description":"A video acquirer acquires video obtained by imaging, by an imaging element that moves in association with motion of a head of a user, an area including reflected light of each of light beams irradiate","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9727130","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.
