Abstract

A handheld electronic device includes a reduced QWERTY keyboard and is enabled with disambiguation software 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 employ contextual data in certain circumstances to prioritize output and to learn new contextual data.

Claims

1. A method of enabling input into a handheld electronic device that comprises an input apparatus, an output apparatus, and a processor apparatus comprising a memory having stored therein a plurality of objects including a plurality of language objects and a number of contextual values, at least some of the language objects each having associated therewith at least a first contextual value, the input apparatus comprising a plurality of input members including a multiple-axis input device, at least some of the input members each having a plurality of linguistic elements assigned thereto, the method comprising:

detecting a first input;

outputting as a first output interpretations of the first input;

detecting as a second input an ambiguous input that comprises a number of input member actuations;

outputting at least a portion of each of a first language object and a second language object as proposed interpretations of the ambiguous input, the at least a portion of the first language object being output at a position of preference with respect to the at least a portion of the second language object;

detecting an input from the multiple-axis input member as a selection of the at least a portion of the second language object and, responsive thereto;

storing a representation of the first output as a contextual value,

associating the contextual value with the second language object.

2. The method of claim 1, further comprising:

detecting another first input;

outputting as another first output an interpretations of the another first input, the first output and the another first output being the same;

detecting as another second input another ambiguous input that comprises another number of input member actuations;

generating an output set comprising at least a portion of each of another first language object and another second language object as proposed interpretations of the another ambiguous input, the second language object and the another second language object being the same;

making a determination that at least one of a representation of the another first input and a representation of the another first output coincides with the contextual value; and

responsive to the making of a determination, outputting the at least a portion of the another second language object at a position of preference with respect to the at least a portion of the another first language object.

3. The method of claim 2, further comprising:

identifying as the additional first language object a word object representative of a relatively higher-frequency ambiguous word;

identifying as the additional second language object a word object representative of a relatively lower-frequency ambiguous word; and

making as said determination a determination that the lower-frequency ambiguous word, in the context of the additional first output, should be output at a position of preference to the higher-frequency ambiguous word.

4. The method of claim 2, further comprising detecting an input from the multiple-axis input member as a selection of the at least a portion of the another first language object and, responsive thereto, deleting the contextual value.

5. The method of claim 1, further comprising:

identifying as the first language object a language object of a length equal to that of the ambiguous input;

identifying as the second language object a language object of a length equal to that of the ambiguous input; and

responsive thereto, initiating said storing and said associating.

6. The method of claim 1, further comprising detecting a rotation of the multiple-axis input member as being the selection of the at least a portion of the second language object.

7. The method of claim 1, further comprising detecting an input from a touch screen display as being the input from the multiple-axis input device.

8. The method of claim 7, further comprising outputting on the touch screen display a depiction representative of the multiple-axis input device.

9. A handheld electronic device comprising:

a processor apparatus comprising a processor and a memory having stored therein a plurality of objects that comprise a plurality of language objects and a number of contextual values, at least some of the language objects each having associated therewith at least a first contextual value;

an input apparatus being structured to provide input to the processor apparatus and comprising a number of input members including a multiple-axis input member;

an output apparatus structured to receive output signals from the processor apparatus;

the memory further 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;

detecting a first input;

outputting as a first output an interpretation of the first input;

detecting as a second input an ambiguous input that comprises a number of input member actuations;

outputting at least a portion of each of a first language object and a second language object as proposed interpretations of the ambiguous input, the at least a portion of the first language object being output at a position of preference with respect to the at least a portion of the second language object;

detecting an input from the multiple-axis input member as a selection of the at least a portion of the second language object and, responsive thereto;

storing a representation of the first output as a contextual value,

associating the contextual value with the second language object.

10. The handheld electronic device of claim 9 wherein the operations further comprise:

detecting another first input;

outputting as another first output an interpretations of the another first input, the first output and the another first output being the same;

detecting as another second input another ambiguous input that comprises another number of input member actuations;

generating an output set comprising at least a portion of each of another first language object and another second language object as proposed interpretations of the another ambiguous input, the second language object and the another second language object being the same;

making a determination that at least one of a representation of the another first input and a representation of the another first output coincides with the contextual value; and

responsive to the making of a determination, outputting the at least a portion of the another second language object at a position of preference with respect to the at least a portion of the another first language object.

11. The handheld electronic device of claim 10 wherein the operations further comprise:

identifying as the additional first language object a word object representative of a relatively higher-frequency ambiguous word;

identifying as the additional second language object a word object representative of a relatively lower-frequency ambiguous word; and

making as said determination a determination that the lower-frequency ambiguous word, in the context of the additional first output, should be output at a position of preference to the higher-frequency ambiguous word.

12. The handheld electronic device of claim 10 wherein the operations further comprise detecting an input from the multiple-axis input member as a selection of the at least a portion of the another first language object and, responsive thereto, deleting the contextual value.

13. The handheld electronic device of claim 9 wherein the operations further comprise:

identifying as the first language object a language object of a length equal to that of the ambiguous input;

identifying as the second language object a language object of a length equal to that of the ambiguous input; and

responsive thereto, initiating said storing and said associating.

14. The handheld electronic device of claim 9 wherein the operations further comprise detecting a rotation of the multiple-axis input member as being the selection of the at least a portion of the second language object.

15. The handheld electronic device of claim 9 wherein at least one of the input and the output apparatus comprises at least a component of a touch screen display, and wherein the operations further comprise detecting an input from the at least component of the touch screen display as being the input from the multiple-axis input device.
