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.

Claims

1. A method of providing an input into a handheld electronic device having an input apparatus, an output apparatus, and a memory, 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 characters assigned thereto, the method comprising:

providing an input interpretation function which, responsive to an ambiguous input of a number of input member actuations, is operable to interpret the ambiguous input;

detecting an input from the multiple-axis input device and, responsive thereto, moving a focus of the handheld electronic device to a particular component of the handheld electronic device;

responsive to the moving of the focus to a particular component, disabling at least temporarily the input interpretation function and providing an alternate input interpretation function;

detecting a number of input member actuations; and

responsive to the detecting of a number of input member actuations, interpreting the number of input member actuations with the alternate input interpretation function.

2. The method of claim 1 wherein the particular component requires a substantially unambiguous input, and further comprising providing a substantially unambiguous input for the particular component by interpreting the number of input member actuations with the alternate input interpretation function.

3. The method of claim 2 wherein the particular component is an input field associated with a password, and further comprising outputting an output comprising a representation of at least a portion of the substantially unambiguous input and, after a predetermined timing interval, altering the output to no longer comprise the representation.

4. The method of claim 1, further comprising providing as the alternate input interpretation function one of a multitap interpretation function, a press-and-hold/press-and-release interpretation function, and an input member chording interpretation function.

5. The method of claim 1, further comprising detecting as the input from the multiple-axis input device a rotational input from the multiple-axis input device.

6. The method of claim 5, further comprising detecting another rotational input from the multiple-axis input device and, responsive thereto, moving the focus from the particular component and ceasing said disabling of the input interpretation function.

7. The method of claim 1 wherein the memory has stored therein a plurality of language objects and a plurality of frequency objects, at least some of the language objects each being associated with an associated frequency object, and wherein the input interpretation function is a text disambiguation function operable to interpret the ambiguous input by:

generating a number of prefix objects corresponding with the ambiguous input,

generating a result by identifying for each of at least some of the prefix objects a corresponding language object having a frequency object associated therewith, and

outputting at least some of the prefix objects of the result to provide a number of proposed disambiguated outputs.

8. The method of claim 7, wherein the operations further comprise employing a multitap text interpretation routine as the alternate input interpretation function.

9. 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.

10. The method of claim 9, further comprising outputting on the touch screen display a depiction representative of the multiple-axis input device.

11. A handheld electronic device comprising:

a processor apparatus comprising a processor and a memory;

an input apparatus being structured to provide input to the processor apparatus and comprising a plurality of input members including a multiple-axis input device, at least some of the input members each having a plurality of characters assigned thereto;

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

the memory having stored therein a number of routines which, when executed on the processor, cause the handheld electronic device to perform operations comprising;

providing an input interpretation function which, responsive to an ambiguous input of a number of input member actuations, is operable to interpret the ambiguous input;

detecting an input from the multiple-axis input device and, responsive thereto, moving a focus of the handheld electronic device to a particular component of the handheld electronic device;

responsive to the moving of the focus to a particular component, disabling at least temporarily the input interpretation function and providing an alternate input interpretation function;

detecting a number of input member actuations; and

responsive to the detecting of a number of input member actuations, interpreting the number of input member actuations with the alternate input interpretation function.

12. The handheld electronic device of claim 11 wherein the operations further comprise detecting as the input from the multiple-axis input device a rotational input from the multiple-axis input device.

13. The handheld electronic device of claim 12 wherein the operations further comprise detecting another rotational input from the multiple-axis input device and, responsive thereto, moving the focus from the particular component and ceasing said disabling of the input interpretation function.

14. The handheld electronic device of claim 11 wherein the memory has stored therein a plurality of language objects and a plurality of frequency objects, at least some of the language objects each being associated with an associated frequency object, and wherein the input interpretation function is a disambiguation routine that is executable on the processor to provide a text disambiguation function which, responsive to an ambiguous input of a number of input member actuations, is operable to interpret the ambiguous input by:

generating a number of prefix objects corresponding with the ambiguous input,

generating a result by identifying for each of at least some of the prefix objects a corresponding language object having a frequency object associated therewith, and

outputting at least some of the prefix objects of the result to provide a number of proposed disambiguated outputs that each have a correspondence with the ambiguous input.

15. The handheld electronic device of claim 14 wherein the alternate input interpretation function is a multitap text interpretation routine.

16. The handheld electronic device of claim 11 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.
