1. A method comprising:
- detecting a touch on a touch-sensitive display of a portable electronic device;
maintaining a first threshold size value for comparing to a contact area value for the touch on the touch-sensitive display;
in response to detecting the touch;
adjusting the first threshold size value based on a time during which touch contact is maintained on the touch-sensitive display, an audio level detected at a microphone of the electronic device, a level of audible noise detected at an active leak microphone of the electronic device, and a light level detected at a light sensor of the electronic device;
comparing the contact area value for the touch to the first threshold size value; and
when the contact area value for the touch meets the first threshold size value, turning off the touch-sensitive display.

Abstract
A method of controlling a portable electronic device includes detecting a touch on a touch-sensitive display, adjusting a first threshold based on detected conditions during the touch, comparing a value related to the touch on the touch-sensitive display to the first threshold, and when the value related to touch meets the first threshold, turning off the display.

20. A method comprising:
-
detecting a touch on a touch-sensitive display of a portable electronic device; maintaining a first threshold for comparing to an area of contact of the touch; adjusting the first threshold based on detected conditions during the touch, including touch contact time, an audio level at a microphone, an input from an accelerometer, a noise level detected at an active leak microphone, input from a light sensor of the portable electronic device, and input from a proximity sensor of the portable electronic device; comparing the area of contact of the touch to the first threshold; when the area of contact of the touch meets the first threshold, turning off the touch-sensitive display.
