  • Patent number: 7175438
    Abstract: A method of interpreting keypad input includes identifying a first letter of a target word from activation of an initial key, identifying a set of possible intermediate letters of the target word in response to non-activating traversal of associated keys of the keypad following activation of the initial key, identifying a last letter of the target word from activation of a final key following the non-activating traversal, and then determining the target word based upon the identified first, intermediate and last letters. The method is particularly useful in key input devices sensitive to non-activating finger position above the keys.
