The first set and second set of keys are arranged to correspond with positions of a set of twelve hours on a clock face and the first set, second set, and third set are concentric with respect to a center, where the ratio of the radii of the first bounding circle, second bounding circle, and third bounding circle is substantially square root of seven, two, and one so that each of the plurality of key areas have substantially of equal area. Each of the at least twenty-eight alphanumeric keys has an indicia surface for being comfortably pressed by a finger."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Clock face keyboard","description":"A compact alphanumeric keyboard providing the clock face familiarity for ease of learning and ease of use, with at least twenty eight alphanumeric keys, where the keys are arranged in a first set of t","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8459885","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.
