Abstract:
1. A method for entering text using a keypad comprising a number of keys fewer than the number of items in the text to be entered, comprising: (a) detecting the actuation of the keys of the keypad; (b) determining if the detected actuation was created by the actuation of one key or the substantially simultaneous actuation of multiple keys by using a stored clock signal to detect a delay for substantially simultaneous actuation of multiple adjacent keys or otherwise the actuation of one key, the act of determining being not executed if a result of an all keys released test is negative, and the act of determining being executed if the result of the all keys released test is positive, enabling a clock from which the stored clock signal originates; (c) if the detected key actuation was created by the actuation of one key chosen from a group of “1”, “2”, “3”, “4”, “5”, “6”, “7”, “8”, “9”, “*”, “0”, and “#”, entering the item associated with the one key that is respectively chosen from a group of “g”, “b”,“e”,“i”,“k”,“n”,“q ”,“u”, “x”, “s”, all caps mode, and backspace function; and (d) if the detected key actuation was created by the substantially simultaneous actuation of multiple keys chosen from a group of “1” and “2”, “2” and “3”, “4” and “5”, “5” and “6 ”, “7” and “8”, “8” and “9”, “*” and “0”, “0” and “#”, “1” and “4”, “2” and “5”, “3” and “6”, “4” and “7”, “5” and “8”, “6” and “9” associated with the multiple keys that is respectively chosen from a group of “a”, “d”, “j”, “m”, “t”,“w”,“z”, numerical mode, “h”,“c”,“f”,“p”,“l”,“o”,“r”,“v”, and “y”.
