Abstract

A handheld electronic device is disclosed. The handheld electronic device comprises a first touch sensing device located in a first region of the handheld electronic device and a second touch sensing device located in a second different region on the handheld electronic device. The handheld electronic device may further include a disabling module to automatically disable the second touch sensing device if a keyboard input is requested and a virtual keyboard is displayed on the first touch sensing device.

Claims

1. A handheld electronic device, comprising:

a first touch sensing device located in a first region of the handheld electronic device;

a second touch sensing device located in a second different region on the handheld electronic device;

a processor; and

instructions executable on the processor to;

automatically disable the second touch sensing device in response to a request for a virtual keyboard input at the handheld electronic device that is without a physical keyboard, the request for the virtual keyboard input responsive to a user interacting with an application of the handheld electronic device, and

display a virtual keyboard on the first touch sensing device in response to the request for the virtual keyboard input responsive to the user interacting with the application of the handheld electronic device, while the second touch sensing device is disabled.

2. The handheld electronic device of claim 1, wherein the first touch sensing device is located over a viewing region on a front side of the handheld electronic device, and the second touch sensing device is located to cover a surface on a back side of the handheld electronic device, the back side opposite to the front side.

3. The handheld electronic device of claim 1, further comprising:

a switch to switch between the first touch sensing device and the second touch sensing device.

4. The handheld electronic device of claim 3, wherein the switch comprises a hardware switch on the handheld electronic device.

5. The handheld electronic device of claim 3, wherein the switch comprises a graphical user interface control element.

6. The handheld electronic device of claim 1, further comprising:

an indicator to inform a user of the disabling of the second touch sensing device.

7. The handheld electronic device of claim 6, wherein the indicator comprises a light or a graphical user interface notification.

8. The handheld electronic device of claim 1, wherein the first touch sensing device comprises a touch screen, and the second touch sensing device comprises a touch surface that is responsive to user touch.

9. The handheld electronic device of claim 8, wherein the touch surface of the second touch sensing device comprises a capacitive sensing touch surface.

10. The handheld electronic device of claim 8, wherein the touch surface of the second touch sensing device comprises a resistive sensing touch surface.

11. A method for operating a handheld electronic device which comprises a first touch sensing device located over a viewing region on a front side of the handheld electronic device, and a second touch sensing device on a back side of the handheld electronic device, the back side opposite to the front side, the method comprising:

determining whether a virtual keyboard input is requested at the handheld electronic device that is without a physical keyboard, the request for the virtual keyboard input responsive to a user interacting with an application of the handheld electronic device;

in response to determining that the virtual keyboard input is requested;

at the handheld electronic device that is without a physical keyboard, automatically disabling the second touch sensing device; and

displaying a virtual keyboard on the first touch sensing device for the virtual keyboard input, while the second touch sensing device is disabled.

12. The method of claim 11, further comprising:

determining whether to switch from the first touch sensing device to the second touch sensing device; and

in response to determining to switch from the first touch sensing device to the second touch sensing device, disabling the first touch sensing device and enabling the second touch sensing device.

13. The method of claim 12, further comprising:

indicating, using an indicator, the disabling of the first touch sensing device to a user.

14. The method of claim 12, wherein the switching is responsive to activating a hardware switch or a software setting.

15. The method of claim 11, wherein the first touch sensing device comprises a touch screen, and the second touch sensing device comprises a touch surface that is responsive to user touch.

16. The method of claim 15, wherein the touch surface of the second touch sensing device comprises a capacitive sensing touch surface.

17. The method of claim 15, wherein the touch surface of the second touch sensing device comprises a resistive sensing touch surface.

18. A handheld electronic device, comprising:

a touch screen located over a viewing region of the handheld electronic device;

a touch sensing device opposite the touch screen, the touch sensing device comprising a touch surface responsive to a user gesture on the touch surface;

a processor; and

a non-transitory storage medium storing instructions executable on the processor to;

determine whether a virtual keyboard input is requested at the handheld electronic device that is without a physical keyboard, the request for the virtual keyboard input responsive to a user interacting with an application of the handheld electronic device;

in response to determining that the virtual keyboard input is requested responsive to the user interacting with the application of the handheld electronic device;

automatically disable the touch sensing device; and

display a virtual keyboard in the touch screen for the virtual keyboard input, while the touch sensing device is disabled.

19. The handheld electronic device of claim 18, wherein the touch surface of the touch sensing device comprises a capacitive sensing touch surface.

20. The handheld electronic device of claim 18, wherein the touch screen is on a front side of the handheld electronic device, and the touch sensing device is on a back side of the handheld electronic device, the front side opposite to the back side.
