The hierarchy of possible choices includes sequences of n possible choices presented within sequences of n operating modes having n predetermined archetypical formats each having at least one fixed characteristic. The interface layer includes an orientation signal generator for generating orientation signals, sensible by the user and uniquely associated with the archetypical formats. Generation of each orientation signal coincides with presentation of its associated archetypical format, to orient the user within the hierarchy."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Interface layer and operating system facilitating use, including by blind and visually-impaired users, of touch-screen-controlled consumer electronic devices","description":"A computerized system for facilitating eye-free use, e.g. by the blind, of an electronic device, the system comprising an interface layer including a hierarchy of operating modes presenting a portion ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9829978","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.
