Abstract

A method includes detecting a touch via a capacitive touch-sensor of a touch-sensitive display, detecting the touch via a resistive touch-sensor of the touch-sensitive display, determining characteristics of the touch from the capacitive touch sensor and the resistive touch sensor, and performing a function based on the characteristics.

Claims (17)

1. A method comprising:

detecting a touch via a capacitive touch sensor of a touch-sensitive display;

detecting the touch via a resistive touch sensor of the touch-sensitive display;

determining characteristics of the touch from the capacitive touch sensor and the resistive touch sensor by determining, utilizing the capacitive touch sensor, a first touch area when the touch is detected by the resistive touch sensor and determining whether a force threshold is exceeded based on a comparison of a second touch area to the first touch area;

performing a function based on the characteristics.

2. The method according to claim 1 , wherein determining characteristics of the touch comprises establishing a difference in a touch location determined utilizing the capacitive touch sensor and a touch location determined utilizing the resistive touch sensor.

3. The method according to claim 2 , wherein determining characteristics of the touch comprises determining a magnitude of the difference and a direction of the difference.

4. The method according to claim 1 , wherein performing the function comprises arranging information on the touch-sensitive display.

5. The method according to claim 1 , wherein performing a function comprises identifying selectable information and performing an associated function.

6. The method according to claim 1 , wherein performing a function comprises identifying and entering a character from a virtual keyboard.

7. The method according to claim 1 , wherein performing a function comprises zooming in response to detecting that a force threshold is exceeded.

8. The method according to claim 1 , wherein performing a function comprises performing a first function when the touch is detected utilizing the resistive touch sensor and performing a second function when a force threshold is exceeded.

9. A non-transitory computer-readable medium having computer-readable code executable by at least one processor of a portable electronic device to perform the method of claim 1 .

10. An apparatus comprising:

a touch-sensitive display comprising a display, and touch-sensitive overlay disposed on the display, the touch-sensitive overlay including a capacitive touch sensor configured to detect a touch and a resistive touch sensor configured to detect the touch when a force threshold is exceeded;

a processor operatively coupled to the touch-sensitive display and configured to determine characteristics of the touch from the capacitive touch sensor and the resistive touch sensor by determining, utilizing the capacitive touch sensor, a first touch area when the touch is detected by the resistive touch sensor and determining whether a force threshold is exceeded based on a comparison of a second touch area to the first touch area, and perform a function based on the characteristics of the touch.

11. A portable electronic device comprising the apparatus of claim 10 .
