By identifying a location where the lines of sight of the users of the mobile communication terminals are concentrated, it is possible to identify an installation location where high advertising effectiveness can be achieved. Moreover, since only acquisition of the position information of the mobile communication terminals is needed, it is possible to efficiently identify an installation location of an advertisement, etc. Therefore, it is possible to efficiently identify an installation location of an advertisement or a billboard where high advertising effectiveness can be achieved."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Location identifying method and location identifying device","description":"In a location identifying method, the sight of users of mobile communication terminals is estimated by calculating directions of the users based on position information of the mobile communication ter","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8509820","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.
