ELECTRONIC KEYBOARD SYSTEM AND METHOD FOR REPRODUCING SELECTED SYMBOLIC LANGUAGE CHARACTERS Abstract of the Disclosure A method and apparatus for electronic typing of symbolic language texts is disclosed. A twelve-key keyboard utilizing a modified four-corner identifier system permits construction of a first shape identifier code utilizing indicia which represent the shape of a character to be reproduced. Alternatively, a phonetic identifier code uti- lizing a phonetic alphabet can be constructed to represent the character. The identifier code is used to select one or more characters stored in a data processing system memory, each character selected by the shape identifier code having the same four-corner identifier indicia, and each character selected by the phonetic identifier code having the same phonetic spelling. Only a limited number of characters can be uniquely identified by either the four-corner system or the phonetic spelling system; for the remainder of the characters, a single set of indicia or a single phonetically spelled word can represent two or more characters, and thus ambiguities exist in the selection process. If the word to be typed comprises a single character, means are provided for manually disambiguating the characters selected by the indicia code. If the word consists of two syllables, means are provided automatically to disambiguate the word in ac- cordance with known character pairings. If more than one such pairing exists for a given identifier code, additional means are provided for manually disambiguating the pairs. Means are provided for storing and/or displaying the unique character or character pair which results from the selection process.
