Abstract

Claims (52)

1. A method for re-mapping a hand-held electronic device, the method comprising:

receiving, at the hand-held electronic device, a plurality of configuration settings for a software application or a class of software applications comprising a text entry application, wherein the configuration settings include physical input elements comprising at least a first input element, a second input element and a third input element, each associated with at least one corresponding function comprising at least one of shift functions or text characters;

modifying a mapping function based on the defined plurality of configuration settings, wherein the mapping function comprises a keyboard device driver, comprising

selectively associating the first input element with at least first and second text characters,

selectively associating the second input element with a first shift function that modifies an executable function for the first input element to the associated first text character upon activation of the second input element, and

selectively associating the third input element with a second shift function that modifies an executable function for the first input element to the associated second text character upon activation of the third input element; and

executing the at least one corresponding function associated with the at least one physical input element upon an activation of the at least one physical input element during operation of the text entry comprising

detecting activation of two of the input elements comprising

one of the second input element or third input element, and

the first input element, and

selectively entering one of the first text character or the second text character corresponding to the second input element or third input element;

wherein executing the at least one corresponding function associated with the at least one physical input element upon an activation of the at least one physical input element during operation of the software application or a software application within the class of software applications comprises:

writing a scan code to a buffer upon the activation of at least one physical input element during operation of the software application or a software application within the class of software applications;

retrieving the scan code from the buffer;

converting the retrieved scan code to a virtual input element code using the modified keyboard device driver;

calling a keyboard event with the scan code and the virtual input element code; and

executing a function associated with the keyboard event, wherein the function is the at least one function.

2. A method for re-mapping a hand-held electronic device, the method comprising:

receiving, at the hand-held electronic device, a plurality of configuration settings for a software application or a class of software applications comprising a text entry application, wherein the configuration settings include physical input elements comprising at least a first input element, a second input element and a third input element, each associated with at least one corresponding function comprising at least one of shift functions or text characters;

modifying a mapping function based on the defined plurality of configuration settings, wherein the mapping function comprises a device layout, comprising

selectively associating the first input element with at least first and second text characters,

selectively associating the second input element with a first shift function that modifies an executable function for the first input element to the associated first text character upon activation of the second input element, and

selectively associating the third input element with a second shift function that modifies an executable function for the first input element to the associated second text character upon activation of the third input element; and

executing the at least one corresponding function associated with the at least one physical input element upon an activation of the at least one physical input element during operation of the text entry comprising

detecting activation of two of the input elements comprising

one of the second input element or third input element, and

the first input element, and

selectively entering one of the first text character or the second text character corresponding to the second input element or third input element;

wherein executing the at least one corresponding function associated with the at least one physical input element upon an activation of the at least one physical input element during operation of the software application or a software application within the class of software applications comprises:

writing a scan code to a buffer upon the activation of the at least one physical input element during operation of the software application or a software application within the class of software applications;

retrieving the scan code from the buffer;

converting the retrieved scan code to a virtual input element code using the modified device layout;

calling a keyboard event with the scan code and the virtual input element code; and

executing a function associated with the keyboard event, wherein the function is the at least one function.

3. A method for re-mapping a hand-held electronic device, the method comprising:

receiving, at the hand-held electronic device, a plurality of configuration settings for a software application or a class of software applications comprising a text entry application, wherein the configuration settings include physical input elements comprising at least a first input element, a second input element and a third input element, each associated with at least one corresponding function comprising at least one of shift functions or text characters;

modifying a mapping function based on the defined plurality of configuration settings, wherein the mapping function comprises a translation layer of a keyboard device driver, comprising

selectively associating the first input element with at least first and second text characters

selectively associating the second input element with a first shift function that modifies an executable function for the first input element to the associated first text character upon activation of the second input element, and

selectively associating the third input element with a second shift function that modifies an executable function for the first input element to the associated second text character upon activation of the third input element; and

executing the at least one corresponding function associated with the at least one physical input element upon an activation of the at least one physical input element during operation of the text entry comprising

detecting activation of two of the input elements comprising

one of the second input element or third input element, and

the first input element, and

selectively entering one of the first text character or the second text character corresponding to the second input element or third input element;

wherein executing the at least one corresponding function associated with the at least one physical input element upon an activation of the at least one physical input element during operation of the software application or a software application within the class of software applications comprises:

writing a scan code to a buffer upon the activation of the at least one physical input element during operation of the software application or a software application within the class of software applications;

retrieving the scan code from the buffer;

converting the scan code to an original virtual input element code;

converting the original virtual input element code to a new input element code using the modified translation layer of the keyboard device driver;

calling a keyboard event with the scan code and the new virtual input element code; and

executing a function associated with the keyboard event, wherein the function is the at least one function.
