Abstract
A method and apparatus for text entry are provided. The method provides a keypad comprising four directional keys and a center selection key, and assigns a set of letters to each of the four directional keys. A representation of the set of letters assigned to each of the four directional keys is provided. A sequence of selected directional keys is received in accordance with a user input, and in accordance with the selected directional keys, the set of letters assigned to each of the selected directional keys are selectively passed to a parsing algorithm. The parsing algorithm determines a user intended text input based upon the passed sequence of letter groupings.

10. A text entry apparatus, comprising:
-
a keypad comprising four directional keys, a center selection key and a menu selection key; and wherein actuation of the menu selection key allows for selection of the type of character to be entered by a user; wherein upon selection of text entry in accordance with the menu selection key, a set of letters are assigned to each of the four directional keys, and actuation of any of the four directional keys passes all of the letters assigned thereto to a parsing algorithm for determining a user intended text input based upon a received sequence of directional keys; wherein upon selection of numbers in accordance with the menu selection key, a set of numbers are assigned to each of the four directional keys; wherein upon selection of symbols in accordance with the menu selection key, a set of symbols are assigned to each of the four directional keys. - View Dependent Claims (11, 12, 13, 14, 15, 16)
