A handheld electronic device 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. Additionally, the device can facilitate the selection of variants by displaying a graphic of a special &#x3c;NEXT&#x3e; key of the keypad that enables a user to progressively select variants generally without changing the position of the user's hands on the device.

Systems, methods, and software can be used to disambiguate an input into a handheld electronic device. In some aspect, one computer-implemented method includes detecting an ambiguous input including one or more selections of one or more input keys; generating one or more prefix objects corresponding with the ambiguous input; generating an output set including at least some of the one or more prefix objects, wherein each of the at least some of the one or more prefix objects is associated with an identified corresponding word object; determining, using a processor, a quantity of prefix objects in the output set is fewer than a predetermined quantity, and, based on the determination, adding as an orphan prefix object to the output set an additional prefix object of the one or more of prefix objects for which a corresponding word object was not identified; and outputting the output set.

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. If a set of characters in the another character learning string match characters in the candidate, the set of characters are stored as a segment.

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. During text entry, a user is able to delimit a language entry session, such as the entering of a word, by actuating a multiple-axis input device or another input device. The user can also reinitiate the language entry session by actuating a linguistic input member at a location abutting the delimited word.

A handheld electronic device is provided with a function of text disambiguation. The device detects an ambiguous input including a number of selections of a number of keys, and displays a plurality of outputs for a duration of time based on an elapsed time between the number of selections of the number of keys. Each of the plurality of outputs corresponds to the ambiguous input. At least one of the plurality of outputs is an orphan prefix corresponding to the ambiguous input.

An improved method of learning a context of a segment of 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 segment of the character interpretation with another segment, a combination object comprising the another segment and a preceding object is stored. In response to another series of inputs, the combination object can be employed by a processing algorithm to ascertain a preference for the another segment in the context of the preceding object of the combination object.

In view of the foregoing, 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. The device also provides a learning function that allows the disambiguation function to adapt to provide a customized experience for the user. In certain predefined circumstances, 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 &#x3c;NEXT&#x3e; key of the keypad that enables a user to progressively select variants generally without changing the position of the user's hands on the device.

A method of disambiguating an input into a handheld electronic device storing a plurality of objects includes a plurality of word objects is described. The method may include detecting an ambiguous input, outputting a number of first character permutations of the ambiguous input that each correspond to one of the word objects, and determining that the first character permutations are fewer in quantity than a predetermined number. The method may further include outputting a number of second character permutations of the ambiguous input that each correspond to an artificial variant.

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 prior to seeking results from other data sources on the device.

A handheld electronic device includes a reduced QWERTY keyboard and is enabled with disambiguation software. The device provides a default output based upon a frequency and variants that are not based solely on frequency. The device enables editing during text entry and also provides a learning function that allows the disambiguation software to adapt to provide a customized experience for the user. The disambiguation function can be selectively disabled.

Methods, handheld electronic devices, and computer-readable media for disambiguating an input into a handheld electronic device, are disclosed. The method includes, for example, detecting an ambiguous input including one or more selections of one or more input characters, generating one or more prefix objects corresponding with the ambiguous input, generating an output set comprising at least some of the one or more prefix objects, each of the at least some of the one or more prefix objects associated with an identified corresponding word object, determining the quantity of prefix objects in the output set is fewer than a predetermined quantity, and, based on the determination, adding as an orphan prefix object to the output set at a position corresponding with a relatively low frequency an additional prefix object of the one or more of prefix objects for which a corresponding word object was not identified, and outputting the output set.
