Abstract: A handheld electronic device includes a reduced QWERTY keyboard and is enabled with disambiguation software. The device provides output in the form of a default output and a number of variants. The output is based largely upon the frequency, i.e., the likelihood that a user intended a particular output, but various features of the device provide additional variants that are not based solely on frequency and rather are provided by various logic structures resident on the device. The device enables editing during text entry and also provides a learning function that allows the disambiguation function to adapt to provide a customized experience for the user. The disambiguation function can be selectively disabled and an alternate keystroke interpretation system provided.

Abstract: A system provides multilanguage text input in a handheld electronic device. The system includes one or more applications implemented in the handheld electronic device. The applications include a text input application requiring access to language data usable thereby. One or more language databases contain language data from a plurality of different languages usable by at least one of the applications including the text input application. An interface provides the applications with access to at least some of the different languages of the language data of the one or more language databases, in order that the applications including the text input application receive the different languages.

Abstract: A method is for input of text symbols into an electronic device having a reduced keyboard. The reduced keyboard has keys representing a plurality of characters. The method includes receiving character inputs from the reduced keyboard and identifying symbol variants based on the received character inputs. A list of symbol variants is displayed. An input symbol from the list of symbol variants is selected, wherein the input symbol is a Korean Hangul syllable. At least one Chinese Hanzi syllable is designated, to correspond to at least one Korean Hangul syllable. The Korean Hangul syllable is replaced with a Chinese Hanzi syllable.

Abstract: An improved method of learning character segments from received text enables facilitated text input on an improved handheld electronic device. In receiving text on the handheld electronic device, the characters of the text are converted into the inputs with which the characters correspond. Then, segments and other objects are analyzed to generate a proposed character interpretation of the series of inputs. Responsive to detecting that at least a portion of the character interpretation differs from a corresponding portion of the received text, a character learning string comprising the differing characters of the received text are stored as a candidate. In response to receiving additional text on the handheld electronic device, the characters of the additional text are converted into the inputs with which the characters correspond. Then, segments and other objects are analyzed to generate another proposed character interpretation of the series of additional inputs.

Abstract: An improved handheld electronic device includes a keypad in the form of a reduced QWERTY keyboard and is enabled with disambiguation software. As a user enters keystrokes, the device provides output in the form of a default output and a number of variants from which a user can choose. The output is based largely upon the frequency, i.e., the likelihood that a user intended a particular output, but various features of the device provide additional variants that are not based solely on frequency and rather are provided by various logic structures resident on the device. The device enables editing during text entry, and when initiating an activity session on a word such as during editing, the display outputs variants of the entire word being edited, rather than providing as variants only those parts of a word that are being edited.

Abstract: A handheld electronic device includes a reduced QWERTY keyboard and is enabled with disambiguation software that is operable to disambiguate compound text input. The device is able to assemble language objects in the memory to generate compound language solutions. The device is able to analyze the combinations of language objects in light of N-gram data stored on the device to avoid proposing low-probability compound language solutions.

Abstract: A handheld electronic device includes a reduced QWERTY keyboard and is enabled with disambiguation software that is operable to disambiguate text input. In addition to identifying and outputting representations of language objects that are stored in the memory and that correspond with a text input, the device is able in certain circumstances of erroneous input to provide proposed corrected output.

Abstract: Systems and methods for input of text symbols into an electronic device comprising a reduced keyboard having keys representing a plurality of characters are disclosed. Possible symbol variants are identified based on character inputs received from the reduced keyboard. Each identified symbol variant is grouped into one of a plurality of groups of symbol variants, each group having an associated priority, according to a type of the symbol variant. Within at least one of the groups, the symbol variants are ranked in decreasing order of frequencies of use of the symbol variants. A list of symbol variants comprising the plurality of groups of symbol variants in order of decreasing priority is then displayed, and an input symbol is selected from the list of symbol variants. The symbol variants of the at least one of the groups of symbol variants are thereby sorted by both priority and frequency of use.

The output is based largely upon frequency of use, but some variants are provided by various logic structures resident on the device. The device enables editing during text entry and also provides a learning function that allows the disambiguation function to adapt. The disambiguation function can be selectively disabled and an alternate keystroke interpretation system provided. Additionally, the device can facilitate the selection of variants by displaying a graphic of a special <NEXT> key of the keypad that enables a user to progressively select variants. If a field into which text is being entered is determined to be a special input field, a disambiguated result can be sought first from a predetermined data source.

Abstract: An improved method of transliterating non-Latin input within an e-mail address field to the Latin equivalent. A routine in a handheld device is structured to detect a triggering event that indicates an e-mail address is being input into an e-mail address field. Following the triggering event, both prior and subsequent input is transliterated to Latin characters as these characters are required by Internet protocols. The transliteration routine may also be utilized to search an e-mail address book wherein names are recorded using both Latin and non-Latin characters.

Abstract: An improved mobile electronic device enables the inputting of text in one alphabet, Traditional Chinese in the present example, by transliteration of inputs in another alphabet, BoPoMoFo in the present example. Since some of the inputs can be ambiguous, transliteration of an ambiguous input is delayed until a detection of a finalization event, thus avoiding the outputting of unnecessary transliteration results, and thus advantageously avoiding a distraction to the user.

Abstract: A handheld device includes a plurality of input members, a first set of which each have a Roman character assigned thereto, a least some of which have a first non-Roman and a second non-Roman character assigned thereto. In response to an actuation of a first one of the input members, a first one of the non-Roman characters that is assigned to the first one of the input members is displayed. Based on one or more rules which govern permissible character sequences in the subject language, the display of a second one of the non-Roman characters in response to an actuation of a second one of the input members having the second one of the non-Roman characters assigned thereto immediately following the actuation of said first one of the input members is prevented.

Abstract: A handheld device includes a plurality of input members, a first set of which each have a Roman character assigned thereto, a least some of which have a first non-Roman, second non-Roman character, and third non-Roman characters assigned thereto. The device is switchable between first and second modes. In the first mode, each Roman character may be input in response to actuation of the input member to which it is assigned, and in the second mode, each first non-Roman character may be input in response to a first type of actuation of the input member to which it is assigned, each second non-Roman character may input in response to a second type of actuation of the input member to which it is assigned, and each third non-Roman character may be input in response to a third type of actuation of the input member to which it is assigned.
