Abstract

An electronic device (300) includes a housing (301). A touch sensitive surface (100) can be disposed along the housing. The touch sensitive surface can include a recessed surface feature (106) on a portion of the touch sensitive surface. A control circuit (315), operable with the touch sensitive surface, can detect a predetermined gesture sequence (501, 502, 503) when a touch actuation along the touch sensitive surface interacts with the recessed surface feature.

Claims

1-20. -20. (canceled)

21. :

An electronic device comprising;

a haptic component configured to deliver a haptic response;

a touch-sensitive surface, wherein the touch-sensitive surface includes a recessed feature within a particular area of the touch-sensitive surface; and

a control circuit configured to;

detect a gesture performed at the particular area of the touch-sensitive surface;

determine whether the gesture is a predetermined gesture; and

responsive to determining that the gesture is the predetermined gesture;

cause the haptic component to deliver the haptic response at the recessed feature; and

perform an operation.

22. :

The electronic device of claim 21, wherein the haptic component includes a transducer configured to deliver the haptic response as user feedback for indicating when the predetermined gesture is detected.

23. :

The electronic device of claim 22, wherein the transducer is a piezoelectric transducer.

24. :

The electronic device of claim 23, wherein the user feedback is a mechanical pop sensation.

25. :

The electronic device of claim 21, further comprising;

a housing; and

a display, wherein the touch-sensitive surface is on a side of the housing that is opposite the display.

26. :

The electronic device of claim 21, wherein the recessed feature comprises a capacitive touch sensor having capacitive electrode pairs defining pixels spanning a surface of the recessed feature.

27. :

The electronic device of claim 26, wherein the control circuit is configured to determine that the gesture is the predetermined gesture when the gesture is detected by at least a predetermined subset of the capacitor electrode pairs.

28. :

The electronic device of claim 21, wherein the control circuit is configured to perform the operation by performing one or more of;

adjusting a volume control of an audio output device of the electronic device;

adjusting a tone control of the audio output device;

adjusting a panning control of a camera of the electronic device;

adjusting a zooming control of the camera;

or

adjusting a scrolling control of a graphical user interface of the electronic device.

29. :

A method comprising;

detecting, by a control circuit of an electronic device, a gesture performed at a particular area of a touch-sensitive surface of the electronic device, wherein the touch-sensitive surface includes a recessed feature within the particular area of the touch-sensitive surface;

determining, by the control circuit, whether the gesture is a predetermined gesture; and

responsive to determining that the gesture is the predetermined gesture;

causing, by the control circuit, a haptic component of the electronic device to deliver a haptic response at the recessed feature; and

performing, by the control circuit, an operation.

30. :

The method of claim 29, wherein the haptic component includes a transducer configured to deliver the haptic response as user feedback for indicating when the predetermined gesture is detected.

31. :

The method of claim 30, wherein the transducer is a piezoelectric transducer.

32. :

The method of claim 31, wherein the user feedback is a mechanical pop sensation.

33. :

The method of claim 29, wherein the recessed feature comprises a capacitive touch sensor having capacitive electrode pairs defining pixels spanning a surface of the recessed feature.

34. :

The method of claim 33, wherein determining that the gesture is the predetermined gesture comprises

determining, by the control circuit, that the gesture is detected by at least a predetermined subset of the capacitor electrode pairs.

35. :

A memory comprising instructions that when executed by a control circuit of an electronic device cause the control circuit to;

detect a gesture performed at a particular area of a touch-sensitive surface of the electronic device, wherein the touch-sensitive surface includes a recessed feature within the particular area of the touch-sensitive surface;

determine whether the gesture is a predetermined gesture; and

responsive to determining that the gesture is the predetermined gesture;

cause a haptic component of the electronic device to deliver a haptic response at the recessed feature; and

perform an operation.

36. :

The memory of claim 35, wherein the haptic component includes a transducer configured to deliver the haptic response as user feedback for indicating when the predetermined gesture is detected.

37. :

The memory of claim 36, wherein the transducer is a piezoelectric transducer.

38. :

The memory of claim 37, wherein the user feedback is a mechanical pop sensation.

39. :

The memory of claim 35, wherein the recessed feature comprises a capacitive touch sensor having capacitive electrode pairs defining pixels spanning a surface of the recessed feature.

40. :

The memory of claim 39, wherein the instructions, when executed, cause the control circuit to determine that the gesture is the predetermined gesture by at least determining that the gesture is detected by at least a predetermined subset of the capacitor electrode pairs.
