Abstract

Provided is a method of processing content based on bio-signals, the method includes: acquiring bio-signals of a user; determining a parameter for altering the characteristics of content or determining a type of content to be output, based on the acquired bio-signals; processing the content or determining the type of content to be output, based on the determined parameter; and outputting the processed content or the determined type of content.

Claims

1. A method of processing content based on bio-signals, the method comprising:

acquiring bio-signals of a user;

determining a parameter for altering the characteristics of content or determining a type of content to be output, based on the acquired bio-signals;

processing the content or determining the type of content to be output, based on the determined parameter; and

outputting the processed content or the determined type of content.

2. The method of claim 1, wherein the determining of the parameter comprises:

determining at least one selected from the group consisting of a user'"'"'s emotional state, sleep state, stress, workload, and concentration level, based on the acquired bio-signals; and

determining a parameter corresponding to the determined user'"'"'s state.

3. The method of claim 1, wherein the bio-signals comprises brainwave signals of the user, and

wherein the parameter is determined based on a user'"'"'s state corresponding to properties of the brainwave signals in a time or frequency domain.

4. The method of claim 1, wherein the parameter comprises at least one selected from the group consisting of a volume, pitch, playback speed, richness of sound, depth, reverberation, thickness, vibration, sensory effect, surround effect, spatial sense, harmony, chord and accompaniment of the content, a region on a display where the content is displayed, colors, brightness, contrast, transparency, focus, power supply, and power consumption of the display, and a type of the content.

5. The method of claim 1, wherein the acquiring of the bio-signals of the user comprises:

outputting at least one object for providing a stimulus to the user;

and acquiring the bio-signals of the user, which are generated while or after outputting the at least one object, and

the method further comprising detecting at least one object corresponding to a response detected from the bio-signals of the user and performing a task corresponding to the detected at least one object.

6. The method of claim 1, further comprising:

determining the user'"'"'s concentration level based on the acquired bio-signals;

obtaining, if the determined user'"'"'s concentration level is less than a reference point, information about content being reproduced; and

providing the obtained information to the user.

7. The method of claim 6, wherein the acquiring of the information about the content comprises acquiring at least one of main details and summary information of the content at a time point when the user'"'"'s concentration level decreases to less than the reference point, or recording and storing broadcast content being reproduced.

8. The method of claim 6, wherein the providing of the obtained information to the user comprises providing the obtained information about the content if the user'"'"'s concentration level is greater than or equal to the reference point, or according to a user'"'"'s input.

9. The method of claim 6, wherein the information about the content is acquired based on at least one selected from the group consisting of big data, per-minute audience ratings, and basic information related to the content that are acquired from an external server.

10. A method of performing user authentication based on bio-signals, the method comprising:

acquiring a bio-signal of a user;

detecting a signal pattern to be compared for the user authentication from the acquired bio-signal;

performing the user authentication by comparing the detected signal pattern against a signal pattern previously modeled for the user authentication; and

updating, if the user authentication is successful, the modeled signal pattern by using the detected signal pattern.

11. The method of claim 10, wherein the user authentication is repeatedly performed while a task requiring the user authentication is being performed.

12. A device for processing content based on bio-signals, the device comprising:

a sensor configured to acquire bio-signals of a user;

a controller configured to determine a parameter for altering the characteristics of content or a type of content to be output based on the acquired bio-signals and process the content or determine the type of content to be output based on the determined parameter; and

an output unit configured to output the processed content or the determined type of content.

13. The device of claim 12, wherein the sensor acquires the bio-signals of the user generated while or after outputting at least one object for providing a stimulus to the user and

wherein the controller detects at least one object corresponding to a response detected from the bio-signals of the user and performs a task corresponding to the detected at least one object.

14. The device of claim 12, wherein the controller determines the user'"'"'s concentration level based on the acquired bio-signals and obtains, if the determined user'"'"'s concentration level is less than a reference point, information about content being reproduced, and

wherein the output unit provides the obtained information to the user.
