1. A method of detecting inputs of marking devices by an electronic device, method comprising:
- generating a first number signal and a second number signal, wherein the first number signal and the second number signal includes first number information and second number signal, respectively;
outputting the first number signal and the second number signal to a first marking device and a second marking device, respectively, wherein the first marking device and the second marking device are for indicating a position on the electronic device;
receiving response signals from the first marking device and the second marking device, wherein the response signals includes first response signal from the first marking device and a second response signal from the second marking device, and the response signals are generated based on response request signals from the electronic device;
identifying a location of the first marking device and a location of the second marking device based on the received response signals; and
displaying the locations of the first marking device and the second marking device on a display of the electronic device.

Abstract
A method of detecting an input of an input marking apparatus includes generating and outputting a number signal to be written to the input marking apparatus, detecting the input marking apparatus in which the number signal is written, by detecting a response signal output from the input marking apparatus, and detecting a position of the input of the input marking apparatus of which the response signal is detected.
