A virtual image light generating unit has a function of generating a plurality of virtual image lights independent of each other and a virtual-image-light transmitting and projecting unit that has a function of transmitting and projecting the virtual image light to left and right eyes of the user through substantially the same optical path to allow a prescribed virtual image video to be visually recognized at a prescribed position within the visual field of the user. Additionally, a virtual-image visual recognition distance control unit that has a function of performing variable control of a visual recognition distance of a virtual image."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Virtual image display device and head mounted display using same","description":"A virtual image display device has a function of projecting a prescribed virtual image video within a visual field of a user and detects an actual visual recognition distance from the user to an objec","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11297304","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.
