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. 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.

Claims (42)

1. A method of enabling a spell-check operation on a handheld electronic device having stored for execution thereon a number of sequentially ordered spell-check algorithms, the method comprising:

subjecting a text entry on the handheld electronic device to a spell-check algorithm to obtain a resultant expression, and seeking for inclusion in a list any language object determined to be consistent with the resultant expression;

subjecting the text entry to a first spell-check algorithm related to misspelling if the quantity of language objects in the list has not reached a predetermined quantity; and

subsequent to said subjecting the text entry to the first spell-check algorithm related to misspelling, and if the quantity of language objects in the list has not reached the predetermined quantity, subjecting the text entry to at least a first spell-check algorithm related to mistyping.

2. The method of claim 1 , further comprising subjecting the text entry to at least a first spell-check algorithm related to character configuration.

3. The method of claim 1 , further comprising employing as the at least first spell-check algorithm related to character configuration at least a first spell-check algorithm related to ignoring at least one of capitalization and accenting.

4. The method of claim 1 , further comprising:

ceasing said subjecting and said seeking as to further spell-check algorithms if the quantity of language objects in the list reaches the predetermined quantity.

5. The method of claim 1 , further comprising employing as the first spell-check algorithm related to misspelling a first spell-check algorithm related to phonetic replacement.

6. The method of claim 1 , further comprising employing as the first spell-check algorithm related to mistyping one of:

a spell-check algorithm related to missing character insertion;

a spell-check algorithm related to character swapping;

a spell-check algorithm related to character omission;

a spell-check algorithm related to one of insertion of a <SPACE>and separation of the entry into a pair of separate sub-entries; and

a spell-check algorithm related to character exchange.

7. The method of claim 1 , further comprising employing as the first spell-check algorithm related to mistyping any two of the following in the gross order of:

a spell-check algorithm related to missing character insertion;

a spell-check algorithm related to character swapping;

a spell-check algorithm related to character omission;

a spell-check algorithm related to one of insertion of a <SPACE>and separation of the entry into a pair of separate sub-entries; and

a spell-check algorithm related to character exchange.

8. The method of claim 1 , further comprising, subsequent to said subjecting the text entry to the first spell-check algorithm related to mistyping, and if the quantity of language objects in the list has not reached the predetermined quantity, subjecting the text entry to a first spell-check algorithm related to metaphone analysis.

9. The method of claim 8 , further comprising employing as the first spell-check algorithm related to metaphone analysis at least a first spell-check algorithm related to generation of a metaphone regular expression.

10. The method of claim 9 , further comprising, subsequent to said subjecting the text entry to the first spell-check algorithm related to generation of a metaphone regular expression, and if the quantity of language objects in the list has not reached the predetermined quantity, subjecting the text entry to a first spell-check algorithm related to metaphone manipulation.

11. The method of claim 10 , further comprising employing as the first spell-check algorithm related to metaphone manipulation one of:

a spell-check algorithm related to missing metaphone key insertion;

a spell-check algorithm related to metaphone key swapping;

a spell-check algorithm related to metaphone key omission; and

a spell-check algorithm related to metaphone key exchange.

12. The method of claim 10 , further comprising employing as the first spell-check algorithm related to metaphone manipulation any two of the following in the gross order of:

a spell-check algorithm related to missing metaphone key insertion;

a spell-check algorithm related to metaphone key swapping;

a spell-check algorithm related to metaphone key omission; and

a spell-check algorithm related to metaphone key exchange.

13. The method of claim 8 , further comprising, subsequent to said subjecting the text entry to the first spell-check algorithm related to mistyping, and prior to said subjecting the text entry to a first spell-check algorithm related to metaphone analysis, and if the quantity of language objects in the list has not reached the predetermined quantity, subjecting the text entry to a first spell-check algorithm related to a predetermined affixation rule.

14. A handheld electronic device comprising an input apparatus, a processor apparatus, and an output apparatus, the input apparatus comprising a number of input keys, at least two of the input keys having a number of linguistic elements assigned thereto, at least two of the input keys each having as the number of linguistic elements assigned thereto a plurality of linguistic elements, the processor apparatus comprising a processor and a memory having stored therein a plurality of objects comprising a plurality of language objects, at least two of the language objects each comprising a number of the linguistic elements, the memory having stored therein a number of routines which, when executed by the processor, cause the handheld electronic device to be adapted to perform operations comprising:

subjecting a text entry to a spell-check algorithm to obtain a resultant expression, and seeking for inclusion in a list any language object determined to be consistent with the resultant expression;

subjecting the text entry to a first spell-check algorithm related to misspelling if the quantity of language objects in the list has not reached a predetermined quantity; and

subsequent to said subjecting the text entry to a first spell-check algorithm related to misspelling, and if the quantity of language objects in the list has not reached the predetermined quantity, subjecting the text entry to a first spell-check algorithm related to mistyping.

15. The handheld electronic device of claim 14 , wherein the operations further comprise subjecting the text entry to a first spell-check algorithm related to character configuration.

16. The handheld electronic device of claim 15 , wherein the operations further comprise employing as the first spell-check algorithm related to character configuration a first spell-check algorithm related to ignoring one of capitalization and accenting.

17. The handheld electronic device of claim 14 , wherein the operations further comprise, ceasing said subjecting and said seeking as to further spell-check algorithms if the quantity of language objects in the list reaches the predetermined quantity.
