18. A method for determining a location of a touch on a touch sensitive display screen, comprising:
-
receiving a coordinate of a capacitance sensor array representing a location of a sensed touch; and determining a coordinate of the display screen corresponding to the sensed touch by performing a rotational transform of the received coordinate based on a relationship between the orientation of the display screen and the orientation of the capacitance sensor array. - View Dependent Claims (19, 20)
