A light sensor responsive to illumination falling on the projection surface measures illumination levels over a predefined image plane associated with the light sensor, producing a projected image signal. A structured light source projects a structured light within the volume of space and a structured light sensor records reflected structured light from objects occupying the volume of space producing a structured light signal. A correlation processor receptive of the projected image signal and said structured light signal and adapted to compute a hybrid signal indicative of the position of an object within said space and from which other information about the object may be extracted."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Hand and object tracking in three-dimensional space","description":"A hybrid system which detects and tracks objects in three-dimensional space using a light source disposed in spaced relation to a projection surface, defining a volume of space illuminated by said lig","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9720511","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.
