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.
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 generally without changing the position of the user's hands on the device. 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.

6. The method of Claim 5, further comprising detecting as at least a portion of the predetermined input a press-and-hold actuation of the particular input member.
7. The method of Claim 5, further comprising detecting as an input of the at least a first new linguistic element at least one of a navigational input and a selection input with respect to a linguistic element of the set of the linguistic elements.
8. The method of Claim 1 wherein the memory has stored therein a map file comprising an assignment of each linguistic element to a corresponding input member, at least some of the linguistic elements in the map file being in the alphabet, further comprising detecting as an input of the at least a first new linguistic element an input of a linguistic element from the map file that is not in the alphabet.
9. The method of Claim 1 wherein the number of objects further comprises a number of frequency objects, at least some of the language objects each being associated with an associated frequency object, and further comprising:
generating a result by, for each prefix object of at least a portion of the number of prefix objects, identifying a language object corresponding with the prefix object, obtaining an associated frequency object associated with the identified language object and having a frequency value, and associating the frequency value with the prefix object;
and outputting as a first output at least some of the prefix objects of the result organized in descending order of frequency value.
generating a result by, for each prefix object of at least a portion of the number of prefix objects, identifying a language object corresponding with the prefix object, obtaining an associated frequency object associated with the identified language object and having a frequency value, and associating the frequency value with the prefix object;
and outputting as a first output at least some of the prefix objects of the result organized in descending order of frequency value.
10. The method of Claim 9, further comprising:
determining that a language object corresponding with the at least one of the prefix objects could not be identified; and outputting as an artificial variant the at least one of the prefix objects at a location of relatively lower priority than the first output.
determining that a language object corresponding with the at least one of the prefix objects could not be identified; and outputting as an artificial variant the at least one of the prefix objects at a location of relatively lower priority than the first output.
