Abstract

A handheld electronic device having a touchscreen and a method of using a touchscreen of a handheld electronic device are provided. In accordance with one embodiment, there is provided a method of input using a touchscreen display of a handheld electronic device, the method comprising: displaying a graphical user interface (GUI) on the touchscreen display, the graphical user interface comprising a plurality of selectable user interface elements, each having an area of the touchscreen display associated herewith and each generating a respective input signal in response to selection thereof; detecting a configuring touch input on the touchscreen display, said configuring touch input having a region of contact wherein upon said configuring touch input, said plurality of selectable user interface elements may subsequently be re-established in accordance with an aspect size of said region of contact.

Claims

1. A method of input using a touchscreen display of a handheld electronic device, the method comprising:

displaying a graphical user interface (GUI) on the touchscreen display, the graphical user interface comprising a plurality of selectable user interface elements, each having an area of the touchscreen display associated herewith and each generating a respective input signal in response to selection thereof;

detecting a configuring touch input on the touchscreen display, said configuring touch input having a region of contact;

wherein upon said configuring touch input, said plurality of selectable user interface elements may subsequently be re-established in accordance with an aspect size of said region of contact.

2. The method of claim 1 wherein said aspect size is the area of said region of contact.

3. The method of claim 1 wherein said aspect size is the width of said region of contact.

4. The method of claim 1 wherein said aspect size is the height of said region of contact.

5. The method of claim 1 wherein said configuring touch is a first touch after device activation.

6. The method of claim 1 wherein said configuring touch is a first touch after a device power off state.

7. The method of claim 1 wherein said configuring touch is a first touch after a device sleep state.

8. The method of claim 1 wherein said configuring touch is a first touch after a transition from a portrait display to a landscape display or vie versa.

9. A handheld electronic device, comprising:

a controller for controlling the operation of the device;

a touchscreen display connected to the controller; and

a position detection subsystem comprising a positional sensor connected to the controller which generates positional signals;

the controller being configured to;

(i) display a graphical user interface (GUI) on the touchscreen display, the graphical user interface comprising a plurality of selectable user interface elements, each having an area of the touchscreen display associated herewith and each generating a respective input signal in response to selection thereof;

(ii) detect a touch input on the touchscreen display having a region of contact;

(iii) determine an aspect size of said region of contact;

(iv) re-establish said selectable user interface elements such that they are in accordance with said aspect size.

10. The device of claim 9 wherein said aspect size is the area of said region of contact.

11. The device of claim 9 wherein said aspect size is the width of said region of contact.

12. The device of claim 9 wherein said aspect size is the height of said region of contact.
