Text input device and method
First Claim
1. A method of data entry for entering text in a language wherein 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, the method comprising:
- activating a first key on which is displayed a first subset of symbols;
displaying a candidate first symbol in response to the step of activating the first key;
activating a second key on which is displayed a second subset of symbols; and
fixing the candidate first symbol and displaying a candidate second symbol in response to the step of activating the second key.

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.

7. A keypad for entering text in a language wherein a character is representable as a first symbol selected from a first set of symbols and a second symbol selected from a second set of symbols, where the first and second sets are mutually exclusive, the keypad comprising:
-
a first set of keys each having marked thereon a plurality of symbols from the first set of symbols; a second set of keys each having marked thereon a plurality of symbols from the second set of symbols; means for activating the first key on which is displayed the first set of symbols; a display for displaying a candidate first symbol in response to the step of activating the first key; means for activating a second key on which is displayed the second set of symbols; and means for fixing the candidate first symbol and displaying a candidate second symbol in response to the step of activating the second key.

-
activating a key of a first set of keys; displaying a candidate first symbol in response to the step of activating a key of the first set of keys; activating a key of a second set of keys; and entering the candidate first symbol and displaying a candidate second symbol in response to the step of activating a key of the second set of keys. - View Dependent Claims (9, 10)

11. A data entry device for entering text in a language wherein a character comprises a first symbol selected from a first set of symbols and a second symbol selected from a second set of symbols, where the first and second sets are mutually exclusive, comprising:
-
a keypad having a first set of keys with the first set of symbols marked thereon and a second set of keys with the second set of symbols marked thereon, where keys of the first and second sets have multiple symbols marked thereon; a display; and a processing device coupled to the keypad and the display operable to cause symbols to be displayed on the display in response to activation of the keys, the processing device causing the display to display a candidate first symbol in response to the activation of the first key, the processing device further fixing the candidate first symbol and causing the display to display a candidate second symbol in response to the activation of the second key. - View Dependent Claims (13, 14)

12. A data entry device for entering text in a language wherein a character comprises a first symbol selected from a first set of symbols and a second symbol selected from a second set of symbols, where the first and second sets are mutually exclusive, comprising:
-
a keypad having a first set of keys with the first set of symbols marked thereon and a second set of keys with the second set of symbols marked thereon, where keys of the first and second sets have multiple symbols marked thereon; a display; and a processing device coupled to the keypad and the display, the processing device operable to cause symbols to be displayed on the display in response to activation of the keys, the processing device having instructions and data stored therein which cause it to change a symbol in the display upon repeated activations of a key and fix a symbol of the first set of symbols in the display upon activation of a key of the second set of keys.
