A handheld electronic device includes a reduced QWERTY keyboard and is enabled with disambiguation software that is operable to disambiguate text input. The device is structured to identify and output representations of language objects that are stored in the memory and that correspond with a text input. The device is additionally structured to identify and output representations of language objects that are stored in the memory and that correspond with a known spelling substitution particular to a language active on the handheld electronic device.

Handheld electronic device and method for disambiguation of text input and providing spelling substitution

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 to generate artificial variants in certain circumstances. Each artificial variant is compared with N-gram data on the handheld electronic device and is suppressed from being output if the artificial variant is determined to have a low probability of being the input intended by a user.

A handheld electronic device includes a reduced QWERTY keyboard and is enabled with a disambiguation routine 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 to perform a spell check routine during input of a text entry. The spell check routine subjects a text entry to a sequentially ordered series of spell-check algorithms and ceases subjecting the text entry to further spell-check algorithms upon identification of a predetermined quantity of spell-check language objects.

Handheld electronic device and method for performing optimized spell checking during text entry by providing a sequentially ordered series of spell-check algorithms

A handheld electronic device includes a reduced QWERTY keyboard and is enabled with a disambiguation routine 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 to perform a spell check routine during input of a text entry and to learn and automatically correct mistakes typically made by the particular user.

Handheld electronic device and method for performing spell checking during text entry and for providing a spell-check learning feature

A handheld electronic device includes a reduced QWERTY keyboard and is enabled with disambiguation software and prediction software. In response to an ambiguous input, the system provides one or more disambiguated interpretations of the ambiguous input. In some circumstances, the system can additionally provide one or more completions, i.e., predictions of future characters. However, in other circumstances the outputting of completions of an ambiguous input can be suppressed in order to avoid distracting the user and to provide more meaningful results to the user.

Handheld electronic device and associated method providing disambiguation of an ambiguous input and selectively providing prediction of future characters

A handheld electronic device includes a reduced QWERTY keyboard and disambiguation software. The device provides output in the form of a default output and variants. The output is based largely upon the likelihood that a user intended a particular output, but the device also provides additional variants that are not based solely on likelihood and are provided by various logic structures on the device. The device enables editing during text entry and a learning function that allows the disambiguation function to adapt for a customized experience. The disambiguation function can be disabled to provide alternate keystroke interpretation. Additionally, the device can facilitate variant selection by displaying a &#x3c;NEXT&#x3e; key to enable variant selection without changing hand position. If an input field into which text is being entered is determined to be special, a disambiguated result can be sought from a predetermined data source prior to other data sources.

Handheld electronic device with text disambiguation allowing dynamic expansion of input key associations

A mobile electronic device includes a touch sensitive display and enables text input to be provided in either a reduced keyboard ambiguous text input mode or in a full keyboard unambiguous text input mode and advantageously enables uncommitted text entered in the ambiguous input mode to be automatically committed when switching into the unambiguous input mode. An improved method employs the mobile electronic device.

A handheld electronic device includes a reduced QWERTY keyboard and is enabled with disambiguation software and prediction software. During editing of an object, the object can be ambiguous, and the system provides one or more disambiguated interpretations of the ambiguous object. In some circumstances, the system can additionally provide one or more completions, i.e., predictions of future characters. However, in other circumstances the outputting of completions of an ambiguous object can be suppressed in order to avoid distracting the user and to provide more meaningful results to the user.

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.

Handheld electronic device and method for dual-mode disambiguation of text input

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.

Handheld electronic device and associated method enabling text input in a language employing non-roman characters

An improved handheld electronic device and associated method provide an advanced editing feature and an improved learning feature that are provided in a disambiguation environment. The advanced editing feature advantageously enables a new word that has been incorrectly disambiguated by a disambiguation routine to be readily corrected by the user without requiring the incorrectly disambiguated word to be deleted and retyped. Rather, the advanced editing feature enables the incorrectly disambiguated characters to be replaced with opposite characters on the same keys, and such changes can be accomplished merely through the use of inputs to a track ball. The newly edited word can then be learned by a learning database. The improved learning function advantageously favors words that are learned using the advanced editing feature over words that have been learned in other fashions.

A method for enabling generation of text on a handheld electronic device which has a plurality of input members, at least some of which have a number of linguistic elements assigned thereto, and a memory having language objects stored therein. The method comprises enabling detection of a number of input member actuations corresponding with an ambiguous input, making at least one of a determination that the number of actuations exceeds a first threshold and a determination that a quantity of predicted language objects corresponding with the ambiguous input is less than a second threshold, generating prefix objects corresponding with the ambiguous input and predicted language objects corresponding with the ambiguous input, each predicted language object comprising a prefix object portion and a completion portion, and providing at a text input location an output comprising a prefix object and a completion portion of a first predicted language object.

Word completion in a handheld electronic device

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 email address book wherein names are recorded using both Latin and non-Latin characters.
