摘要:
A method of controlling a portable electronic device having a touch-sensitive display includes detecting a first touch on the touch-sensitive display, detecting a second touch on the touch-sensitive display while the first touch is maintained, selecting one of the first and second touches as a selected touch based on start or end times of the first and second touches, and determining which one of a plurality of features is associated with a location of the selected touch.

A touch screen display of an electronic device is calibrated. The method includes receiving input comprising selections of features registered at the touch screen display, filtering the input based on characteristics determined during the receiving to determine if the input is to be used for calibrating, for each input used for calibrating, determining a difference between registered touch location and a respective target for the selection and subtracting an offset from the difference, thereby providing remainders of differences for the selections, and calibrating by adjusting a prior calibration based on the remainders if the input is determined to be used for calibrating.

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.
