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.

Claims

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 information, 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 based on the first response signal from the first marking device and a location of the second marking device based on the second response signal from the second marking device; and

displaying the locations of the first marking device and the second marking device on a display of the electronic device,

wherein the identifying the location of the first marking device and the location of the second marking device comprises identifying the location of the first marking device based on a relative amplitude of the first response signal received through a plurality of antennas installed in the electronic device and the location of the second marking device based on a relative amplitude of the second response signal received through the plurality of antennas installed in the electronic device.

2. The method of claim 1, further comprising receiving number acceptance signals from the first marking device and the second marking device, wherein the number acceptance signals comprises a first number acceptance signal from the first marking device and a second number acceptance signal from the second marking device.

3. The method of claim 1, wherein the first marking device corresponds to a first color, the second marking device corresponds to a second color.

4. The method of claim 3, wherein the displaying the locations of the first marking device and the second marking device comprises displaying the location of the first marking device as the first color, and displaying the location of the second marking device as the second color.

5. The method of claim 1, wherein the displaying the locations of the first marking device and the second marking device comprises displaying the location of the first marking device and the location of the second marking device, simultaneously.

6. The method of claim 1, further comprising receiving information of a pen pressure of the first marking device from at least one of the first marking device and the second marking device.

7. The method of claim 6, further comprising transmitting a pen pressure request signal to at least one of the first marking device and the second marking device.

8. The method of claim 1, further comprising receiving additional information from at least one of the first marking device and the second marking device.

9. The method of claim 8, further comprising transmitting an additional information request signal to at least one of the first marking device and the second marking device.

10. The method of claim 8, wherein the additional information comprises at least one of a serial number, a manufacturer, and property information.

11. The method of claim 1, wherein the first response signal comprises the first number information, and the second response signal comprises the second number information.

12. The method of claim 1, wherein the response request signals from the electronic device are associated with one of the first number information or the second number information.
