  • Patent number: 7706616
    Abstract: A word pattern recognition system based on a virtual keyboard layout combines handwriting recognition with a virtual, graphical, or on-screen keyboard to provide a text input method with relative ease of use. The system allows the user to input text quickly with little or no visual attention from the user. The system supports a very large vocabulary of gesture templates in a lexicon, including practically all words needed for a particular user. In addition, the system utilizes various techniques and methods to achieve reliable recognition of a very large gesture vocabulary. Further, the system provides feedback and display methods to help the user effectively use and learn shorthand gestures for words. Word patterns are recognized independent of gesture scale and location. The present system uses language rules to recognize and connect suffixes with a preceding word, allowing users to break complex words into easily remembered segments.

  • Patent number: 7487461
    Abstract: A command pattern recognition system based on a virtual keyboard layout combines pattern recognition with a virtual, graphical, or on-screen keyboard to provide a command control method with relative ease of use. The system allows the user conveniently issue commands on pen-based computing or communication devices. The system supports a very large set of commands, including practically all commands needed for any application. By utilizing shortcut definitions it can work with any existing software without any modification. In addition, the system utilizes various techniques to achieve reliable recognition of a very large gesture vocabulary. Further, the system provides feedback and display methods to help the user effectively use and learn command gestures for commands.

  • Publication number: 20080270896
    Abstract: A system, method and computer-readable medium that previews words and commands recognized by a continuous stroke recognizer based on input into a virtual keyboard layout is presented. The system and method allows a user to see the word that will be recognized or output before the user commits the continuous stroke input to the system. Further, after recognition and output, the system presents the recognized output word and the closest word candidates in a correction display integrated with the virtual keyboard layout. Among other things, the user is provided with options to change the current output word by selecting another word candidate on the correction display, and to delete the current output word by selecting the representation of the current output word on the correction display.

  • Publication number: 20070094024
    Abstract: A word pattern recognition system improves text input entered via a shorthand-on-keyboard interface. A core lexicon comprises commonly used words in a language; an extended lexicon comprises words not included in the core lexicon. The system only directly outputs words from the core lexicon. Candidate words from the extended lexicon can be outputted and simultaneously admitted to the core lexicon upon user selection. A concatenation module enables a user to input parts of a long word separately. A compound word module combines two common shorter words whose concatenation forms a long word.
