Input guessing systems, methods, and computer program products

摘要

Provided are systems for acceleration of text input for electronic devices, such as efficient and user-friendly input guessing systems for mobile phones. An input guessing system disambiguates user input to decrease the number of required key strokes for entry of desired input. An input guessing system uses one or more of optimal selection of a candidate word and position of the cursor within or after the candidate word based on minimization of expectation of the total weighted number of input events for all words, advanced disambiguating of input events, reduced ambiguity of a group containing a letter in a current position of the cursor, smart processing of word endings, advanced delimiting of words using an OK key, automatic addition of spaces, simple error correction, the ability to generate words with embedded special accented characters by typing the key associated with the unaccented version of the letter, and the ability to automatically disambiguate among multiple punctuation characters assigned to a single key based on the context of the keystroke to accelerate and simplify user input.
