Abstract:
1. A method for selecting an intended word entered using a reduced keypad, where each of one or more keys of the reduced keypad is mapped to a plurality of letters, the method comprising: for an entered key input indicative of pressing one or more keys in the reduced keypad using a single-tap approach in which one of the keys mapped to a plurality of letters is pressed only once for each letter such that each key press is mapped to only one letter, determining one or more sequences of letters as the intended word based on a score for each of the one or more sequences of letters; and presenting the one or more sequences of letters as the intended word, where a user selects the intended word from the one or more sequences of letters, without resorting to a multiple-tap approach in which one of the keys mapped to a plurality of letters is pressed at least once for each letter, such that a number of times one of the keys is pressed indicates only one letter, and where the user can indicate, without resorting to the multiple-tap approach, an accepted one or more initial letters of the intended word from the one or more sequences of letters, the one or more initial letters having less letters than the intended word, to cause redetermination of the one or more sequences of letters presented as the intended word as a function of the accepted one or more initial letters.
