VIRTUAL KEYBOARD TEXT ENTRY METHOD OPTIMIZED FOR THUMB TYPING, USING PARTIAL WORD COMPLETION KEY ENTRY VALUES

摘要

Virtual keyboards become efficient and ergonomic by typing with small, incremental partial word completions, using fewest but largest possible keys, presented in highly condensed layouts, retaining familiar structural patterns of standard keyboards like QWERTY, and utilizing curved thumb typing formats. The keyboard continuously adjusts numbers of keys, key sizes, predictive values and layouts, to minimize keystrokes, reduce errors, and maximize potential words entered, while providing the most ergonomic, minimalist interface possible at any moment, scaling to any size device. Keys display normal default characters concatenated with supplemental predictive characters, forming incremental partial word completions; each represents the longest common building block shortcut of likely intended words derivable from a key's default value. The most relevant keys can generate larger numbers of highly predicted words; the more relevant, the larger the key. Only the most relevant keys are displayed, in stripped down, but familiar layouts, allowing only valid text entry options.
