Abstract

There is provided an electronic device and method for calibration of a touch screen using a biometric sensor. The touch screen includes a display and a touch sensor associated with the display. The biometric sensor is configured to detect a user input. The display and/or the touch sensor of the touch screen are calibrated based on the user input detected at the biometric sensor.

Claims

1. An electronic device having a user interface, the electronic device being capable of calibrating the user interface, the device comprising:

a biometric sensor configured to detect a user input;

a touch screen including a display and a touch sensor; and

at least one processor configured to calibrate at least one of the display or the touch sensor of the touch screen based on the user input detected at the biometric sensor.

2. The electronic device of claim 1, wherein the biometric sensor is a fingerprint sensor capable of detecting linear movement across the fingerprint sensor and capturing a biometric pattern in response to the linear movement.

3. The electronic device of claim 1, wherein the touch sensor is associated with the display and overlays at least part of the display.

4. The electronic device of claim 1, wherein the touch sensor is positioned at an outer surface of the device without overlaying the display.

5. The electronic device of claim 1, wherein the biometric sensor detects a size of the user input.

6. The electronic device of claim 5, wherein the touch sensor includes a plurality of input regions, and the at least one processor calibrates a region size of one or more input regions of the touch sensor based on the size of the user input.

7. The electronic device of claim 5, wherein the display includes a plurality of visual regions, and the at least one processor calibrates a region size of one or more visual regions of the display based on the size of the user input.

8. The electronic device of claim 5, wherein the biometric sensor detects a linear dimension of the user input.

9. The electronic device of claim 1, wherein the display of the touch screen is activated in response to the biometric sensor detecting the user input when the display is inactive.

19. The method of claim 1, further comprising authenticating the user input.

20. The method of claim 1, further comprising:

detecting that the display is inactive; and

activating the display of the touch screen in response to detecting the user input and detecting that the display is inactive.

10. A method of an electronic device for calibration of a touch screen using a biometric sensor, the method comprising:

detecting a user input at the biometric sensor; and

configuring the touch screen in response to detecting the user input at the biometric sensor.

11. The method of claim 10, wherein detecting a user input at the biometric sensor includes detecting linear movement across a fingerprint sensor and capturing a biometric pattern in response to the linear movement.

12. The method of claim 10, wherein the touch screen includes a display and a touch sensor.

13. The method of claim 12, wherein the touch sensor is associated with the display and overlays at least part of the display.

14. The method of claim 12, wherein the touch sensor is positioned at an outer surface of the device without overlaying the display.

15. The method of claim 10, wherein detecting a user input at the biometric sensor includes detecting a size of the user input.

16. The method of claim 15, wherein configuring the touch screen includes configuring a region size of one or more input regions of the touch sensor based on the size of the user input.

17. The method of claim 15, wherein configuring the touch screen includes configuring a region size of one or more visual regions of the display based on the size of the user input.

18. The method of claim 15, wherein detecting a user input at the biometric sensor includes detecting a linear dimension of the user input.
