  • Alphanumeric data entry apparatus and method using multicharacter keys of a keypad
    Patent number: 8296484
    Abstract: A method and apparatus for predicting the desired alphanumeric character of a depressed multi-character key of a reduced-key keypad based upon the previous selection of characters. Rule trees defining the prediction associated with a depressed key based upon the previous selection of characters are dynamically built upon use to readily function with all language styles and vocabularies. Moreover, the rule trees are weighted to increase the probability of predicting the desired character and to be quickly adaptable to different users having different language styles or vocabularies.
