According to the technical solutions of the embodiments of this application, an encoded pattern is decoded by overlaying a decoding template to an encoded pattern in at least one eye fundus of a user, so that a specific user can conveniently and intuitively see information hidden in the encoded pattern directly on the spot."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"System, device, and method for information exchange","description":"The application discloses an information exchange method and an information exchange system, the method including: overlaying at least one decoding template onto an encoded pattern in at least one eye","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9836857","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.
