A plurality of direction keys for determining a shifting direction of an object within an OSD image are provided beneath a surface of a touch pad (110) and are arranged to perform corresponding functions of the touch pad (110). The controller (101) includes a touch pad (110) having a predetermined touch pattern; a coordinate recognition unit (120) for recognizing coordinate values corresponding to a touch trajectory executed with respect to the touch pad (110); a key signal input unit (130), having a plurality of key input buttons, for generating a key signal according to a user selection of at least one of the key input buttons, the plurality of key input buttons disposed beneath the touch pad (110) and arranged according to the predetermined pattern; a system controller (140) for calculating values of at least one of a direction, speed, and distance of the touch trajectory using the recognized coordinate values and for outputting a command signal based on the calculated values and the key signal; and a key code generator (150) for generating a key code corresponding to the command signal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method of generating key code in coordinate recognition device and video device controller using the same","description":"A controller (101) and method for generating a key code enable key code generation by a single instance of manipulation of the controller (101) by a user, obviating repetitive keypad manipulation and ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8525803","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.
