1. A method for input ideographic characters comprising the steps of:
- (a) entering an input sequence into a user input device;
wherein said user input device comprises;
a plurality of input means, each of said input means being associated with a plurality of strokes or phonetic characters, and an input sequence being generated each time when an input is selected by said user input device;
data consisting of a plurality of input sequences and, associated with each input sequence, an input method specific database containing a plurality of input sequences and, associated with each input sequence, a set of phonetic sequences whose spellings correspond to the input sequence or a set of strokes sequences corresponding to the input sequence; and
an ideographic database containing a set of ideographic character sequences, wherein each ideographic character contains an ideographic index, a plurality of stroke indices to corresponding stroke sequences and a plurality of phonetic indices to corresponding phonetic sequences;
(b) comparing the input sequence with said input method specific database and finding indices to matching strokes entries or phonetic entries and said matching stroke entries or phonetic entries;
(c) converting said matching indices to stroke entries or phonetic entries to matching ideographic indices;
(d) retrieving matching ideographic character sequences from said ideographic database by said matching ideographic indices; and
(e) optionally displaying one or more of said matched ideographic character sequences.

Abstract
A system and method for inputting Chinese characters using phonetic-based or stroke-based input method in a reduced keyboard is disclosed. By introducing common indices to ideographic characters, the system allows the ideographic characters to be shared among different type of input methods such as phonetic-based input method and stroke-based input method. The system matches input sequences to input method specific indices such as phonetic or stroke indices. These input method specific indices are then converted into indices to ideographic characters, which is then used to retrieve ideographic characters.
