Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 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 duration during which the touch is detected by the touch-sensitive display and touch contact…
