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

摘要

Text entry with short, incremental, partial word completions improves virtual keyboard efficiency; ergonomics are improved by far fewer, but far larger, more relevant keys, 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 and reduce errors, while providing the most ergonomic, minimalist interface possible at any moment, scaling to any size device. Keys display normal default characters but concatenated with supplemental predictive values, each representing 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; these longer more precise values provide look ahead spelling guidance, reducing misspellings.
