PORTABLE ELECTRONIC DEVICE INCLUDING TOUCH-SENSITIVE DISPLAY AND METHOD OF DETERMINING WHEN TO TURN OFF THE TOUCH SENSITIVE DISPAY

摘要

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.

主权项

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 by increasing or decreasing the first threshold size value based on at least two of:
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;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; andwhen the contact area value for the touch meets the first threshold size value, turning off the touch-sensitive display.
