Abstract
In a method of operating a touch screen, an object interaction is detected with the touch screen while in a first doze mode. It is determined if a detected object interaction with the touch screen is a valid input object interaction with the touch screen. In response to determining the object interaction is a valid input object interaction, the touch screen is transitioned from the first doze mode to a gesture recognition mode. The touch screen is transitioned from the gesture recognition mode to an active mode in response to a determination of a valid gesture interaction with the touch screen by the input object.
