    Abstract: Languages based in whole or in part on ideographic characters such as Chinese, Japanese, and Korean, are often are entered in a computerized text-entry system in a two-phase process. In the first phase, symbols from a first pre-conversion set are entered, then in the second phase, these pre-conversion symbols are converted into a second set of post-conversion symbols. This invention teaches a method and apparatus for the automatic conversion of pre-conversion symbols into post-conversion symbols without requiring an explicit conversion signal to be input by the user. It accomplishes this goal though the design of trigger sequences of keystrokes which are substantially functionally equivalent to an explicit conversion signal input by the user. An apparatus constructed according to the trigger sequence method is particularly well adapted for use on reduced keyboards, and in conjunction with predictive text-entry methods. Explicit constructions are shown for Chinese, Japanese, and Korean.

  • Patent number: 8032357
    Abstract: A keypad is used to enter complex characters using a phonetic input method editor (IME). The user may enter complex characters by combining consonants, vowels, mid-vowels and tones by selecting keys on a the keypad instead of using a full size keyboard. Instead of a one-to-one mapping between the symbols and keys on a full size keyboard, multiple symbols are assigned to single keys on the keypad. For example, on a keypad having ten keys an average of four phonetic symbols are mapped to each of the ten keys on the keypad. The phonetic symbols are applied to the keypad in layers. For example, the symbols may be may be mapped to a consonant layer; a middle vowels+vowels layer; a vowels layer and a tone layer. Phonetic symbols with similar readings may also be mapped to the same key.

  • Patent number: 7719521
    Abstract: A text input mechanism is provided especially for non-keyboard input devices for inputting text for languages that include large numbers of characters and that are not based on the Roman alphabets. Reading symbols of a language are presented to the user for selection. Reading symbols can be phonetic symbols for composing a pronunciation for a character in the language. Reading symbols can also be sub-characters that make up characters in the language. Upon a user specifying one or more reading symbols for a character, all characters in the language that match the specified reading symbols are dynamically identified and displayed to the user. The user can select the desired character from the displayed characters. The selected character is then entered into a computing system.

  • Patent number: 7595742
    Abstract: A diacritic chording system uses a single standard keyboard layout to generate diacritical characters used, for example, by Latin-based languages or languages based on a Roman character set, providing a universal keyboard The key combination required to select a diacritic is consistent, independent of the language the user is typing. The diacritic chording system uses chording to obtain characters modified by diacritics, i.e., diacritical characters. The key combinations in the diacritic chord are chosen in such a way to aid memorization by positional association of the keys or by logic association of the keys within the diacritic chord. The use of a combination of positional association and logical association eliminates conflicts in mapping diacritics for different languages. The diacritic chording system also provides a screen overlay as a mnemonic to illustrate which diacritic chords provide the desired diacritical character.

    Abstract: A Japanese Hiragana input character string of “a-i” is displayed while a single Japanese Hiragana character of “ti” is displayed as a display character for representing a “ta” row key assigned with a “ta” row character group of “ta”, “ti”, “tu”, “te”, and “to”. When a user then appoints the “ta” row key, “ti” is added to the tail end of the input character string to newly form the input character string of “a-i-ti” containing three characters. When each of “ka” and “ki” does not effectively follow “a-i-ti” in tree structure index data, a display character for a “ka” row key assigned with “ka”, “ki”, “ku”, “ke”, “ko” is switched into “ku” while skipping “ka” and “ki”. Further, when “tu” does not effectively follow “a-i-ti” in the index data, a display character for the “ta” row key is switched from “ti” into “te” while skipping “tu”.
