Abstract
Signals are transmitted from a plurality of regions of an electronic device. Location information is then received from an electronic pen in proximity to the electronic device. The location information is determined by the electronic pen and corresponds to a location of the electronic pen relative to the screen of the electronic device. The location information is determined using one or more of the transmitted signals received by the electronic pen. Aa display on the screen of the electronic device is controlled based at least in part on the received location information. A more efficient pen operating state is thereby provided that improves the user experience by more accurately and reliably determining the pen location in space.
