Abstract
A method includes transmitting, by a touch screen device, signals on electrodes. The method further includes detecting, by a pen, a signal of the signals via an electrode of the electrodes. The method further includes creating, by the pen, a representation of the signal and transmitting the representation of the signal in accordance with a pen recognition signal format. The method further includes detecting, by the touch screen device, a change in the electrical characteristic of the electrode that is caused by the representation of the signal. The method further includes determining, by the touch screen device, that the pen is causing the change to the electrical characteristic of the electrode based on the pen recognition signal format.
