Abstract

A display apparatus, a vehicle, and a display method are disclosed, which recognize the user's intention by recognizing the user's eyes, and apply the recognized result to a device control process, thereby greatly increasing convenience of the input unit manipulation actions of the user. A display apparatus includes: a controller configured to insert a visual stimulus signal into basic visual information according to a predetermined frequency; a display unit configured to display the visual stimulus signal for generating an electroencephalogram (EEG) signal and the basic visual information; and an EEG analyzer configured to determine a frequency occupied by the generated EEG signal.

First claim

What is claimed is:

1 . A display apparatus comprising:
a controller configured to insert a visual stimulus signal into basic visual information according to a predetermined frequency; a display unit configured to display the visual stimulus signal for generating an electroencephalogram (EEG) signal and the basic visual information; and an electroencephalogram (EEG) analyzer configured to determine a frequency occupied by the generated EEG signal.

2 . The display apparatus according to claim 1 , wherein the EEG signal generated by the visual stimulus signal includes a steady-state visual evoked potential (SSVEP).

3 . The display apparatus according to claim 1 , wherein the display unit displays the basic visual information in a form of moving images or still images.

4 . The display apparatus according to claim 3 , wherein:
if the basic visual information is displayed in the form of moving images, the controller inserts the visual stimulus signal at a specific time at which a frame constructing the moving images is not displayed.

5 . The display apparatus according to claim 1 , further comprising:
a communication unit configured to receive the generated EEG signal from an electroencephalogram detector for detecting the EEG signal of a user.

6 . The display apparatus according to claim 5 , wherein the EEG analyzer recognizes the user's eyes on the basis of the frequency occupied by the generated EEG signal.

7 . The display apparatus according to claim 1 , wherein the controller generates a control signal to activate a function corresponding to the frequency occupied by the generated EEG signal.

8 . The display apparatus according to claim 1 , wherein the controller divides a screen image of the display unit into a plurality of regions, and inserts visual stimulus signals having different frequencies into basic visual information displayed on the divided regions.

9 . A vehicle comprising:
a controller configured to insert a visual stimulus signal into basic visual information according to a predetermined frequency; a display unit configured to display the visual stimulus signal for generating an electroencephalogram (EEG) signal and the basic visual information; a communication unit configured to receive an EEG signal from an EEG detector for detecting an EEG signal of a user; and an electroencephalogram (EEG) analyzer configured to determine a frequency occupied by the EEG signal of the user, and determine a region gazed by the user on the basis of the determined frequency.

10 . The vehicle according to claim 9 , wherein the electroencephalogram (EEG) signal generated by the visual stimulus signal includes a steady-state visual evoked potential (SSVEP).

11 . The vehicle according to claim 10 , wherein the display unit includes a plurality of displays.

12 . The vehicle according to claim 11 , wherein the controller inserts visual stimulus signals having different frequencies into basic visual information respectively displayed on the plurality of displays.

13 . The vehicle according to claim 12 , wherein the controller controls a function related to the display gazed by the user from among the plurality of displays.

14 . The vehicle according to claim 13 , further comprising:
an input unit configured to receive a control command from the user, wherein the controller controls a function related to the user-gazed display according to a control command received from the input unit manipulated by the user.

15 . The vehicle according to claim 9 , wherein the controller inserts different visual stimulus signals into different visual information displayed on different regions of the display unit.

16 . The vehicle according to claim 15 , wherein the controller, if the user gazes at one of the regions of the display unit, immediately executes a function corresponding to the one of the regions, such that the immediately executed function is determined to be a shortcut function.

17 . The vehicle according to claim 16 , wherein the controller determines the function frequently used by the user or the function frequently gazed by the user to be the shortcut function.

18 . The vehicle according to claim 9 , further comprising:
a speaker configured to output an acoustic or sound signal.

19 . The vehicle according to claim 18 , wherein the controller, if the user gazes at the display unit during a predetermined reference time or more, outputs a warning message through at least one of the display unit and the speaker.

20 . The vehicle according to claim 18 , wherein the controller, if the user does not gaze at traffic lights, outputs a warning message through at least one of the display unit and the speaker.

21 . The vehicle according to claim 18 , wherein the controller, if the user gazes at a red light from among traffic lights, and if the vehicle does not stop driving, outputs a warning message through at least one of the display unit and the speaker.

22 . The vehicle according to claim 9 , wherein the display unit enlarges a display size of a region corresponding to a function frequently used by the user or a display size of a region frequently gazed by the user.

23 . The vehicle according to claim 9 , wherein the display unit includes an Audio Video Navigation (AVN) display, a cluster display, and a head-up display.

24 . A display apparatus comprising:
a controller configured to insert a visual stimulus signal into basic visual information according to a predetermined frequency; and a display unit configured to display the visual stimulus signal for generating an electroencephalogram (EEG) signal and the basic visual information.

25 . A vehicle for receiving an electroencephalogram (EEG) signal of a user who gazes at an advertisement display device that displays not only basic visual information but also a visual stimulus signal inserted into the basic visual information according to a predetermined frequency, comprising:
an EEG analyzer configured to determine a frequency occupied by the EEG signal of the user, and determine a region gazed by the user on the basis of the determined frequency; and a controller, if the user-gazed region is the advertisement display device, configured to provide information associated with the advertisement display device through a display unit or an output unit.

26 . The vehicle according to claim 25 , wherein the display unit includes an Audio Video Navigation (AVN) display, a cluster display, and a head-up display.

27 . The vehicle according to claim 26 , wherein the head-up display displays information associated with the advertisement display device using an augmented reality technology.

28 . A display method comprising:
inserting a visual stimulus signal into basic visual information according to a predetermined frequency; receiving an electroencephalogram (EEG) signal of a user; determining a region gazed by the user by analyzing the received EEG signal; and performing a control function corresponding to the user-gazed region.

29 . The display method according to claim 28 , wherein the determining the user-gazed region includes:
determining a frequency occupied by the received EEG signal; and determining whether the determined frequency is identical to the predetermined frequency of the visual stimulus signal.
