The head-mounted display device has a second image inputting unit that acquires a binocular image of a wearer. The head-mounted display device is configured so that a control unit determines, from the binocular image of the wearer acquired by the second image inputting unit, that the wearer is awake when both eyes are closed for no longer than a predetermined period of time and that the wearer is asleep when both eyes are closed for a predetermined period of time or longer, and the display unit displays the external world image acquired by the first image inputting unit when the wearer wakes from sleep."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Head-mounted display device","description":"A video transmissive head-mounted display device capable of avoiding danger to a user when worn by the user has an external world image acquired by a first image inputting unit, and the external world","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11971550","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.
