The control section identifies feature points for each component that exist in a series of acceleration data, generates feature point data for each component which includes the plurality of feature points as inputted character data, and collates it with basic character data."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Character recognition device and recording medium","description":"A character recognition device which recognizes an operation for writing a character performed by a housing including an acceleration sensor while being moved in a spatial plane based on a measurement","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8538156","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.
