  • Reduced keyboard text input system for the Japanese language
    Patent number: 6646573
    Abstract: A reduced keyboard system for the Japanese language which uses word-level disambiguation of entered keystroke sequences, and which enables the user to select the desired interpretation of an ambiguous input key sequence as kana, and then select the desired textual interpretation associated with the selected kana interpretation. The system uses a highly compressed database format which has several advantages in terms of reduced size and minimal processing requirements during operation. Also disclosed is a reduced keyboard system which uses sequences of two keystrokes to specify each syllable, including the syllables with palatalized vowels that are written with two kana each. Input sequences of keystrokes are interpreted as ordered pairs of keystrokes which select a character according to its position in a two-dimensional matrix. The first keystroke of each ordered pair specifies the row of the matrix in which the desired character appears, and the second keystroke of each pair specifies the column.
