Abstract

A text input device (10) and a method of data entry for entering text in a language (e.g. Zhuyin phonetic Chinese), in which a character is representable as a first symbol selected from a first subset of symbols and a second symbol selected from a second subset of symbols, where the first and second subsets are mutually exclusive. A first key on which is displayed a first subset of symbols is activated (e.g. any one of keys 1-6). A candidate first symbol is displayed in response to the step of activating the first key. A second key is activated on which is displayed a second subset of symbols (e.g. any one of keys 7-0). The candidate first symbol is fixed and a candidate second symbol is displayed in response to activating the second key. A third key can be activated (e.g. any one of keys 7-0), on which is displayed a further subset of symbols, whereupon the candidate second symbol is fixed.
