detecting, by the panel, at least a first electromagnetic signal output by a pen device; and responsive to detecting the first electromagnetic signal output by the pen device, initiating at least a first process of a plurality of processes based on detecting the first electromagnetic signal output by the pen device.

2 . The method of claim 1 , further comprising;
identifying at least a portion of a plurality of frequencies contained in the first electromagnetic signal; wherein the first process is determined based on identifying at least the portion of the plurality of frequencies contained in the first electromagnetic signal.

3 . The method of claim 1 , wherein the first electromagnetic signal is an electromagnetic noise signal detected by the pen device and passively output by the pen device.

4 . The method of claim 1 , wherein the first electromagnetic signal is an electromagnetic noise signal detected by the pen device and output by an electromagnetic signal generator of the pen device.

5 . The method of claim 1 , further comprising:
determining a duration of time the first electromagnetic signal is detected by the panel; wherein the first process is selected based on the duration of time the first electromagnetic signal is detected by the panel.

6 . The method of claim 1 , further comprising:
detecting, by the panel, a second electromagnetic signal output by the pen device, the second electromagnetic signal including at least one frequency not contained in the first electromagnetic signal; identifying the at least one frequency included in the second electromagnetic signal that is not contained in the first electromagnetic signal; and responsive to identifying the at least one frequency included in the second electromagnetic signal that is not contained in the first electromagnetic signal, initiating at least a second process based on detecting the second electromagnetic signal output by the pen device.

7 . The method of claim 1 , further comprising:
detecting, by at least one sensor external to the panel, the first electromagnetic signal output by the pen device; and responsive to detecting, by the at least one sensor external to the panel, the first electromagnetic signal output by the pen device, initiating at least a second process.

8 . A method of outputting at least a first electromagnetic signal by a pen device, comprising:
outputting at least a first electromagnetic signal by the pen device, wherein detection of the first electromagnetic signal causes initiation of a first process of a plurality of processes at a device.

9 . The method of claim 8 , further comprising:
detecting, by the pen device, at least one electromagnetic noise signal external to the pen device; wherein the pen device passively outputs the electromagnetic noise signal as the first electromagnetic signal.

10 . The method of claim 8 , further comprising:
detecting, by the pen device, at least one electromagnetic noise signal external to the pen device; wherein the pen device outputs the electromagnetic noise signal using an electromagnetic signal generator of the pen device.

11 . The method of claim 8 , further comprising:
outputting at least a second electromagnetic signal, the second electromagnetic signal including at least one frequency not contained in the first electromagnetic signal.

12 . The method of claim 8 , further comprising:
receiving at least one user input by the pen device; and responsive to receiving the at least one user input, outputting a second electromagnetic signal, the second electromagnetic signal including at least one frequency not contained in the first electromagnetic signal.
