Abstract: A reduced keyboard disambiguating system for the Korean language using word-level disambiguation to resolve ambiguities in keystrokes. A plurality of letters are assigned to each of a plurality of data keys, so that keystrokes on these keys are ambiguous. A user may enter a keystroke sequence wherein each keystroke corresponds to the entry of one letter of a word. Because individual keystrokes are ambiguous, the keystroke sequence can potentially match more than one word with the same number of letters. The keystroke sequence is processed by matching the input keystroke sequence to corresponding stored words or other interpretations. The 14 consonant jamos of the Korean alphabet are assigned to the data keys in their standard alphabetical sequence. The 10 vowel jamos are likewise assigned to the same set of data keys in their standard alphabetical sequence, such that a majority of the data keys are assigned both one or more consonant jamos and one or more vowel jamos.

Abstract: A reduced keyboard disambiguating computer. The keyboard has twelve keys, nine of them labeled with numerous letters and other symbols, and those nine plus one more are labeled each with one of the ten digits. Textual entry keystrokes are ambiguous. The user strikes a delimiting "select" key at the end of each word, delimiting a keystroke sequence which could match any of many words with the same number of letters. The keystroke sequence is processed with a complete dictionary, and words which match the sequence of keystrokes are presented to the user in order of decreasing frequency of use. The user selects the desired word. The letters are assigned to the keys in a non-sequential order which reduces chances of ambiguities. The same "select" key is pressed to select the desired word, and spacing between words and punctuation is automatically computed. For words which are not in the dictionary, two keystrokes are entered to specify each letter.
