Input mode selector on a mobile device

摘要

A table stores a list of possible character input modes comprising modes for selecting characters from a non-alpha numeric character set and alpha numeric character set. A selector selects a new character input mode different from the identified one of the modes listed in the table, in response to a mode change command input by a user by operating a character key (108). Independent claims are also included for the following: (1) current character input mode changing method; (2) mobile device; (3) computer readable medium recording current character input mode changing program; and (4) computer system.
