Abstract
A layout for a keypad is provided that has a highly regular arrangement of alphabetic characters for ease of use thereof and a highly efficient distribution of the characters to minimize the instances where multiple words are formed from a given sequence of key inputs. The keypad layout is for the Chinese phonetic Bopomofo alphabet. The keypad layout utilizes a top-down approach to provide the desired regularity so that commonly known sets of the characters appear in an assigned column therefor but not in other columns. Further, the character groups have their sets distributed amongst the key columns in a balanced fashion to minimize ambiguity in character input. Where a separate navigation key is not available, an alternative nine-key layout utilizing the above principles is disclosed.
