Document Type and Number:
WIPO Patent Application WO2004003721
Kind Code:

Abstract:
In entering text into an electronic device with a keypad having a number of keys, each key represents a plurality of characters. A character is entered by the corresponding key and selected among the plurality of characters by pressing the key a number of times corresponding to the character. To each key is attached, in addition to the plurality of characters, a further, ambiguous character representing any one of the plurality of characters. A key sequence is activated such that an ambiguous characters sequence comprising at least one ambiguous character is generated. Possible non-ambiguous character sequences corresponding to the ambiguous character sequence are generated and compared with a vocabulary stored in a memory and comprising character sequences representing words occurring in a given language. Those possible character sequences that match character sequences in said vocabulary are pre-selected. One of the pre-selected character sequences is selected and enterd into the device.
