Abstract

An improved handheld electronic device having a reduced keyboard provides facilitated language entry by making available to a user certain words that a user may reasonably be expected to enter. In some situations, certain words can be stored, for example, in a temporary dictionary for use in particular situations. For instance, the names of the recipients of an electronic message might be stored in a temporary dictionary for rapid retrieval when entering a salutation in the message. As another example, a number of the words in an existing electronic message may be stored in a temporary dictionary and made available to a user when replying to or forwarding the message since the existing message might include words that the user might reasonably be expected to type in the reply message or the forwarded message.

Claims

1. A method of enabling disambiguation of an input into a handheld electronic device, the handheld electronic device including an input apparatus, an output apparatus, and a memory having a plurality of objects stored therein, the plurality of objects including a plurality of language objects and a plurality of frequency objects, each of at least a portion of the language objects of the plurality of language objects being associated with an associated frequency object of the plurality of frequency objects, the input apparatus including a plurality of input members, each of at least a portion of the input members of the plurality of input members having a plurality of linguistic elements assigned thereto, the method comprising:

initiating on the handheld electronic device a second message in response to a first received message, the first received message having a sender, the second message including the sender as a recipient of a number of recipients;

storing in the memory a first language object from the first received message, the first language object corresponding to the sender of the first received message;

associating a relatively high frequency value with the first language object from the first received message;

detecting an ambiguous input for the second message, the ambiguous input including a number of input member actuations of a number of the input members of the plurality of input members, each of at least a portion of the input members of the number of input members including a number of linguistic elements assigned thereto, at least one of the input members of the number of input members having a plurality of linguistic elements assigned thereto, wherein the ambiguous input is at least a portion of a salutation of the second message;

determining that the first language object stored in the memory corresponds with the ambiguous input for the second message; and

outputting an output including at least a portion of the first language object as a first proposed disambiguation of the ambiguous input.

2. The method of claim 1, further comprising outputting as the at least a portion of the output the recipient and another recipient of the number of recipients as the first proposed disambiguation of the ambiguous input.

3. The method of claim 1, further comprising:

determining that a second language object of the number of language objects corresponds with the ambiguous input; and

outputting as at least another portion of the output at least a portion of the second language object as a second proposed disambiguation of the ambiguous input.

4. The method of claim 1, further comprising determining that the ambiguous input is at a location adjacent at least a first salutatory expression of a number of predetermined salutatory expressions in a language input field of the second message.

5. The method of claim 1, further comprising determining that the ambiguous input is on an initial line of a language input field of the second message.

6. The method of claim 1, further comprising storing in a first portion of the memory at least a portion of the recipients of the number of recipients of the second message.

7. The method of claim 6, further comprising seeking in the first portion of the memory said recipient that corresponds with the ambiguous input.

8. The method of claim 7, further comprising, responsive to said determining that the ambiguous input is at least a portion of a salutation, performing said seeking in the first portion of the memory said recipient that corresponds with the ambiguous input.

9. The method of claim 1 wherein:

the first received message further includes at least one recipient; and

the second message includes the at least one recipient of the first received message as at least one of the number of recipients.

10. A method of enabling disambiguation of an input into a handheld electronic device, the handheld electronic device including an input apparatus, an output apparatus, and a memory having a plurality of objects stored therein, the plurality of objects including a plurality of language objects and a plurality of frequency objects, each of at least a portion of the language objects of the plurality of language objects being associated with an associated frequency object of the plurality of frequency objects, the handheld electronic device having a number of received messages available thereon, the input apparatus including a plurality of input members, each of at least a portion of the input members of the plurality of input members having a plurality of linguistic elements assigned thereto, the method comprising:

detecting a replying input with respect to a first received message of the number of received messages available on the handheld electronic device, the first received message having at least a sender;

initiating on the handheld electronic device a second message including the sender as a recipient of a number of recipients, and storing in the memory a first language object from the first received message, the first language object corresponding to the sender of the first received message;

associating a relatively high frequency value with the first language object from the first received message;

detecting an ambiguous input for the second message, the ambiguous input including a number of input member actuations of a number of the input members of the plurality of input members, each of at least a portion of the input members of the number of input members including a number of linguistic elements assigned thereto, at least one of the input members of the number of input members having a plurality of linguistic elements assigned thereto, wherein the ambiguous input is at least a portion of a salutation of the second message;

determining that the first language object stored in the memory corresponds with the ambiguous input for the second message; and

outputting an output, the output including at least a portion of the first language object as a first proposed disambiguation of the ambiguous input.

11. The method of claim 10, further comprising storing in a first portion of the memory at least a portion of the recipients of the number of recipients of the second message.

12. The method of claim 11, further comprising identifying in the first portion of the memory said recipient of the number of recipients.

13. The method of claim 11, further comprising:

determining that a second language object in a second portion of the memory corresponds with the ambiguous input; and

outputting as at least another portion of the output at least a portion of the second language object as a second proposed disambiguation of the ambiguous input.

14. The method of claim 10, further comprising outputting as the at least a portion of the output the recipient and another recipient of the number of recipients as the first proposed disambiguation of the ambiguous input.

15. The method of claim 10, further comprising determining that the ambiguous input is at a location adjacent at least a first salutatory expression of a number of predetermined salutatory expressions in a language input field of the second message.

16. The method of claim 10, further comprising determining that the ambiguous input is on an initial line of a language input field of the second message.

17. The method of claim 10, wherein:

the first received message further includes at least one recipient; and

the second message includes the at least one recipient of the first received message as at least one of the number of recipients.

18. A handheld electronic device comprising:

a processor apparatus including a memory having a plurality of objects stored therein, the plurality of objects including a plurality of language objects and a plurality of frequency objects, each of at least a portion of the language objects of the plurality of language objects being associated with an associated frequency object of the plurality of frequency objects;

an input apparatus including a plurality of input members, each of at least a portion of the input members of the plurality of input members having a plurality of linguistic elements assigned thereto;

an output apparatus;

the processor apparatus being adapted to initiate on the handheld electronic device a second message in response to a first received message, the first received message having a sender, the second message including the sender as a recipient of a number of recipients;
