Abstract: An improved method of learning character segments during text input enables facilitated text input on an improved handheld electronic device. In response to a series of inputs, segments and other objects are analyzed to generate a proposed character interpretation of the series of inputs. Responsive to detecting a replacement of a character of the character interpretation with another character, a character learning string comprising the another character and a number of additional characters of the character interpretation are stored as a candidate. In response to another series of inputs, another proposed character interpretation is generated. Responsive to detecting another replacement of a character of the another character interpretation with a different character, another character learning string comprising the different character and a number of characters of the another character interpretation are compared with the stored candidate.

Abstract: A method for input of text symbols into an electronic device having a reduced keyboard is disclosed. The reduced keyboard has keys representing a plurality of characters. The method comprises receiving character inputs from the reduced keyboard. The method also comprises identifying symbol variants based on the received character inputs. The method further comprises displaying a list of symbol variants. The method further comprises receiving a symbol selected from the list of symbol variants. The symbol is a syllable in a first language. The method further comprises identifying syllable variants in a second language corresponding to the syllable in the first language. The method further comprises receiving an input syllable selected from the syllable variants in the second language.

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 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 provides a learning function which facilitates providing proposed corrected output by the device in certain circumstances of erroneous input.

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 generate compound language solutions by employing different groupings of data sources to generate different portions of the compound language solutions.

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 prioritize compound language solutions according to various criteria.

During text entry, a user is able to delimit a language entry session, such the entering of a word, by actuating a multiple-axis input device or another input device.

Abstract: An improved handheld electronic device and associated method employing an improved spell checking routine enable proposed spelling corrections having a close logical proximity to an active input to be output at a position of preference for easy selection by the user. By way of example, a base character and the various accented forms thereof can be said to have a logical proximity to one another that is closer than their logical proximity to any character having a different base character, whether additionally having a diacritical element or not.

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 prioritize compound language solutions according to various criteria, including the degree of completeness of the text components of a compound language solution.

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 includes a number of non-alphabetic characters that are assigned to keys and that can be accessed directly by the text disambiguation software without the need to active a non-alphabetic input routine or to additionally actuate and <SHIFT> key or an <ALT> key, for instance.

Abstract: A method for enabling input into a handheld electronic device having at least three selectable languages available thereon includes detecting a predetermined input a number of times and switching a selected language between one of the three selectable languages and another of the three selectable languages wherein the another language is an immediately preceding selected language.

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: A method includes receiving a character in response to a touch on a touch-sensitive display, adding the character to a character string, identifying, from stored data, objects that at least partially match the character string, and determining a next character of at least one of the objects identified, yielding a set of next characters.

Abstract: A handheld electronic device includes a reduced QWERTY keyboard and is enabled with disambiguation software that is operable to disambiguate text input. In response to an ambiguous editing input at a location preceding at least a portion of an output word, the software performs one disambiguation operation with respect to the editing input and another disambiguation operation with respect to the editing input in combination with the at least portion of the output word. The results are output in order of decreasing frequency value, with the results of the one disambiguation operation having the portion of the output word appended thereto.

Abstract: A device is provided for executing a method for providing context based predictive text entry. The device has a processor and a keyboard, a display screen, and a storage device connected to the processor. The method comprises receiving an input from the keyboard, the input comprising a character of a string; gathering relevant contextual data based on the input; retrieving any relevant stored data from the storage device based on the input; generating at least one context based prediction based on the received input, the contextual data, and any relevant stored data; displaying at least one option for completing the string on the display screen based on the at least one prediction; and completing the string if one of the options displayed on the display screen is selected by way of a further input.
