Systems and methods for word identification that use button press type error analysis

摘要

Systems, devices and methods are disclosed for error correction in text input systems that use time-dependent button presses. A frequent error type in time-based text input is errors due to inaccurately timed button presses. The result of mistimed button presses is errant button press types within a button press type sequence. An error correction algorithm identifies possible alternative button press type sequences based on the number of button presses in the sequence. The algorithm converts the alternative button press type sequences to alternative character sequences using the received button press value sequence. The algorithm compares the alternative character sequences and the presumed word with a library of known words to determine the word most likely intended by a user.
