The method includes the steps of: acquiring a two-dimensional detected light intensity distribution caused by the pointing object acting on the three-dimensional interaction display; obtaining two light-shading intensity maximum values according to the two-dimensional detected light intensity distribution; and determining a one-dimensional positional information of the pointing object on a distance direction of the pointing object relative to the three-dimensional interaction display by use of the positional distance between the two light-shading intensity maximum values."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method of determining pointing object position for three-dimensional interactive system","description":"An exemplary method of determining a pointing object position for three-dimensional interactive system, adapted for an interaction between a pointing object and a three-dimensional interaction display","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8531458","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.
