Abstract

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, with the output from the spell check routine being visually integrated into the output from the disambiguation routine.

Claims

1-14. -14. (canceled)

15. A method for enabling input on a handheld electronic device having a display, the method comprising:

detecting a plurality of input key selections as an initial portion of an ambiguous input;

outputting at a first location on the display the initial portion of an ambiguous input;

identifying a plurality of prefix objects corresponding to the initial portion of the ambiguous input, each of the plurality of prefix objects associated with an initial portion of a language object being a proposed textual interpretation of the ambiguous input;

outputting at a second location on the display the plurality of prefix objects; and

upon selection of a prefix object, outputting at the first location on the display the prefix object, wherein the outputted prefix object differs from the initial portion of the ambiguous input.

16. The method of claim 15, wherein the plurality of prefix objects is outputted in responsive to a preceding input member actuation, and a second plurality of prefix objects is outputted in responsive to a current input member actuation, wherein the second plurality of prefix objects includes at least one prefix object associated with the previously selected prefix object.

17. The method of claim 15, wherein the number of letters in the prefix object equal to the number of letters in the initial portion of the ambiguous input.

18. The method of claim 15, further comprising detecting as the ambiguous input a misspelled input, and wherein the plurality of prefix objects includes an object being a proposed spelling correction.

19. The method of claim 18, further comprising outputting an indication that the object is a proposed spelling correction.

20. The method of claim 19, wherein the indication that the object is a proposed spelling correction includes a visual indication.

21. The method of claim 15, wherein the language object retrieved from an address database.

22. The method of claim 15, wherein the language object retrieved from a speed-text database.

23. The method of claim 15, wherein the plurality of prefix objects are presented based on relative probabilities of the corresponding language objects.

24. The method of claim 15, wherein the outputted prefix object having an arrangement of the linguistic elements other than the arrangement of the linguistic elements of the initial portion of the ambiguous input.

32. The handheld electronic device of claim 24, wherein the language object retrieved from a speed-text database.

25. A handheld electronic device, comprising:

an input apparatus;

a display;

at least one processor configured to;

detect a plurality of input key selections as an initial portion of an ambiguous input;

cause outputting at a first location on the display the initial portion of an ambiguous input;

identify a plurality of prefix objects corresponding to the initial portion of the ambiguous input, each of the plurality of prefix objects being an initial portion of a language object associated with a proposed textual interpretation of the ambiguous input;

cause outputting at a second location on the display the plurality of prefix objects; and

upon selection of a prefix object, cause outputting at the first location on the display the prefix object, wherein the prefix object differs from the initial portion of the ambiguous input.

26. The handheld electronic device of claim 25, wherein the plurality of prefix objects is outputted in responsive to a preceding input member actuation, and a second plurality of prefix objects is outputted in responsive to a current input member actuation, wherein the second plurality of prefix objects includes at least one prefix object associated with the selected prefix object.

27. The handheld electronic device of claim 25, wherein the number of letters in the prefix object equal to the number of letters in the initial portion of an ambiguous input.

28. The handheld electronic device of claim 25, wherein the at least one processor further configured to detect as the ambiguous input a misspelled input, and wherein the plurality of prefix objects includes an object being a proposed spelling correction.

29. The handheld electronic device of claim 28, wherein the at least one processor further configured to cause outputting an indication that the object is a proposed spelling correction.

30. The handheld electronic device of claim 29, wherein the indication that the object is a proposed spelling correction includes a visual indication.

31. The handheld electronic device of claim 25, wherein the language object retrieved from an address database.

33. The handheld electronic device of claim 25, wherein the plurality of prefix objects are presented based on relative probabilities of the corresponding language objects.

34. The handheld electronic device of claim 25, wherein the outputted prefix object having an arrangement of the linguistic elements other than the arrangement of the linguistic elements of the initial portion of the ambiguous input.
