Abstract
There is disclosed a method for entering ideographic characters from a keypad of a mobile communications device such as a mobile phone. Each of the keys in the keypad of the mobile communications device corresponds to a character pattern or structure. On selection by user of one of these patterns, the device presents the user with a selection of possibilities for a first component of the selected pattern. Assuming that the pattern includes more than one component then, on selection by the user of one of the possibilities for the first component, the user is presented with a series of possibilities for a second component, and so on until the character has been composed from the relevant components. Since the pattern of a desired character can be determined relatively unambiguously, it is relatively easy for the user to enter the character correctly.
