outputting, by the information-providing device, the sound signal,

wherein the object information comprises the object identification information that identifies a location of the information of interest.

2. The method of claim 1 , wherein the information-providing device comprises a display,

wherein the user input indicates a selection of a part of content displayed on the display, and

wherein the determining the information of interest comprises determining the selected part of the content as the information of interest.

3. The method of claim 1 , wherein the information-providing device comprises a display,

wherein the method further comprises displaying, on the display, an information-of-interest determining button configured to receive the user input, and

wherein the determining the information of interest comprises receiving the user input using the information-of-interest determining button.

4. A method of an information-receiving device of receiving information from an information-providing device, the method comprising:

receiving, by the information-receiving device, a sound signal comprising object information;

obtaining, by the information-receiving device, the object information included in the sound signal;

downloading, by the information-receiving device, information of interest based on the object information; and

outputting, by the information-receiving device, the downloaded information of interest,

wherein the object information comprises object identification information that identifies a location of the information of interest,

wherein the downloading of the information of interest comprises:

transmitting, by the information-receiving device, a request comprising the object identification information to a server; and

receiving, by the information-receiving device, the information of interest from the server in response to the request, and

wherein the sound signal is generated by the information-providing device in response to detecting a physical movement of the information-providing device.

5. The method of claim 4 , wherein the information of interest comprises an image generated by capturing a part of a screen displayed on a display of the information-providing device.

6. A method of sharing information, which is performed by a system that comprising an information-providing device, an information-receiving device, and a server, the method comprising:

determining, by the information-providing device, information of interest based on a user input to the information-providing device;

uploading, by the information-providing device, the determined information of interest to the server;

transmitting, by the server, object identification information configured to be used to identify the uploaded information of interest to the information-providing device;

generating, by the information-providing device, a sound signal comprising object information in response to detecting a physical movement of the information-providing device;

transmitting, by the information-receiving device, a request comprising the object identification information, to the server; and

transmitting, by the server, the uploaded information of interest to the information-receiving device in response to the request,

wherein the object information comprises the object identification information.

7. The method of claim 6 , wherein the information-providing device comprises a display,

wherein the user input comprises an input indicating a selection of a part of content displayed on the display, and

wherein the determining of the information of interest comprises determining, by the information-providing device, the selected part of the content as the information of interest.

8. The method of claim 6 , wherein the object information further comprises at least one selected from among a command to download the information of interest to be performed by the information-receiving device, user identification information, device identification information, and a token configured to be used to determine whether the request for the information of interest is valid.

9. An information-providing device comprising:

a user interface configured to receive a user input;

a processor configured to determine information of interest based on the user input;

a sensor configured to detect a physical movement of the information-providing device;

a transceiver configured to transmit the information of interest to a server, to receive object identification information from the server; and

an audio output unit configured to generate a sound signal comprising object information corresponding to the information of interest based on the received object identification information, in response to the sensor detecting the physical movement of the information-providing device,

wherein the object information comprises the object identification information that identifies a location of the information of interest.

10. The information-providing device of claim 9 , further comprising a display,

wherein the user input comprises a touch input indicating a selection of a part of content displayed on the display, and

wherein the processor is further configured to determine the selected part of the content as the information of interest.

11. An information-receiving device comprising:

a user interface configured to receive a sound signal comprising object information from a information-providing device;

a processor configured to obtain the object information included in the sound signal;

a transceiver configured to download information of interest based on the object information; and

a display unit configured to display the information of interest,

wherein the object information comprises object identification information that identifies a location of the information of interest, and

wherein the transceiver is further configured to transmit a request including the object identification information to a server, and to receive the information of interest from the server in response to the request, and

wherein the sound signal is generated by the information-providing device in response to detecting a physical movement of the information-providing device.

12. The information-receiving device of claim 11 , wherein the information of interest comprises an image generated by capturing a part of a screen displayed on the display unit.

13. A non-transitory computer-readable recording storage medium having stored thereon a computer program, which when executed by a computer, performs the method of claim 1 .
