Abstract

A vehicle is provided to include a bio-signal sensor that detects a bio-signal of a user, a display device that displays an image and a controller that determines at least one of a positivity of the user or change amount of the positivity of the user based on the detected bio-signal. The controller accumulates a positivity index when at least one of the positivity or change amount of the positivity is equal to or greater than a predetermined positivity or a predetermined change amount of the positivity and transmit a control signal to the display device to display the accumulated positivity index.

First claim

What is claimed is:

1. A vehicle, comprising:
a bio-signal sensor configured to detect a bio-signal of a user;
a display device configured to display an image; and
a controller configured to
determine at least one of a positivity of the user or change amount of the positivity of the user based on the detected bio-signal,
accumulate a positivity index when at least one of the positivity or change amount of the positivity is equal to or greater than a predetermined positivity or a predetermined change amount of the positivity, and
transmit a control signal to the display device to display the accumulated positivity index,
wherein the display device is configured to display a cymatics image which is transformed according to a frequency, and the controller is configured to determine at least one of a frequency or size of the cymatics image in proportion to the positivity index, and transmit a control signal to the display device to display the cymatics image having at least one of the determined frequency or size.

2. The vehicle according to claim 1 , wherein: the controller is configured to transmit a control signal to the display device to display a predetermined image when the positivity index reaches a target positivity index.

3. The vehicle according to claim 1 , further comprising:
a feedback device configured to operate to increase the positivity of the user;
wherein the controller is configured to transmit a signal to the feedback device to operate when the positivity index reaches a target positivity index.

4. The vehicle according to claim 3 , wherein the feedback device includes vibration elements disposed on a seat of the vehicle, and the controller is configured to transmit at least one of a control signal for the vibration elements to vibrate at a predetermined frequency or a control signal for the vibration elements to vibrate at a predetermined intensity or more.

5. The vehicle according to claim 3 , wherein the feedback device includes a speaker disposed within the vehicle, and the controller is configured to transmit a control signal for the speaker to output a predetermined sound.

6. The vehicle according to claim 3 , wherein the feedback device includes a lighting device disposed within the vehicle, and the controller is configured to transmit at least one of a control signal for the lighting device to emit light at a predetermined frequency, a control signal for the lighting device to emit light at a predetermined brightness, or a control signal for the lighting device to emit light in a predetermined color.

7. The vehicle according to claim 3 , wherein the feedback device includes an air-conditioner disposed within the vehicle, and the controller is configured to transmit at least one of a control signal for the air-conditioner to output a predetermined scent or a control signal for the air-conditioner to output wind of a predetermined mode.

8. The vehicle according to claim 1 , wherein the controller is configured to reset the positivity index to an initial value when the positivity index reaches a target positivity index.

9. The vehicle according to claim 1 , further comprising:
a camera configured to obtain image data for the user;
wherein the controller is configured to determine the positivity of the user based on at least one of the image data for the user or the bio-signal of the user.

10. The vehicle according to claim 1 , further comprising:
an inputter configured to receive information of at least one of an initial value of the positivity index or a cumulative condition of the positivity index.

11. The vehicle according to claim 1 , wherein the controller is configured to transmit the control signal for the display device to display the accumulated positivity index in a form of at least one of a numeral, an emoticon indicating an emotional state, gauge bar, or a letter.

12. A vehicle control method, comprising:
detecting, by a controller, a bio-signal of a user using a sensor;
determining, by the controller, at least one of a positivity of the user or change amount of the positivity of the user based on the detected bio-signal;
accumulating, by the controller, a positivity index when at least one of the positivity or change amount of the positivity is equal to or greater than a predetermined positivity or a predetermined change amount of the positivity; and
displaying, by the controller, the accumulated positivity index,
further comprising:
determining, by the controller, at least one of a frequency or size of a cymatics image in proportion to the positivity index; and
displaying, by the controller, the cymatics image having at least one of the determined frequency or size.

13. The vehicle control method according to claim 12 , further comprising:
displaying, by the controller, a predetermined image when the positivity index reaches a target positivity index.

14. The vehicle control method according to claim 12 , further comprising:
transmitting, by the controller, a control signal to operate a feedback device when the positivity index reaches a target positivity index.

15. The vehicle control method according to claim 14 , wherein the feedback device includes vibration elements disposed on a seat of a vehicle, and the transmitting of the control signal for operating the feedback device when the positivity index reaches the target positivity index includes:
transmitting, by the controller, at least one of a control signal for the vibration elements to vibrate at a predetermined frequency or a control signal for the vibration elements to vibrate at a predetermined intensity or more.

16. The vehicle control method according to claim 14 , wherein the feedback device includes a speaker disposed within a vehicle, and the transmitting of the control signal for operating the feedback device when the positivity index reaches the target positivity index includes:
transmitting, by the controller, a control signal for the speaker to output a predetermined sound.

17. The vehicle control method according to claim 14 , wherein the feedback device includes a lighting device disposed within a vehicle, and the transmitting the control signal for operating the feedback device when the positivity index reaches the target positivity index includes:
transmitting, by the controller, at least one of a control signal for the lighting device to emit light at a predetermined frequency, a control signal for the lighting device to emit light at a predetermined brightness, or a control signal for the lighting device to emit light in a predetermined color.

18. The vehicle control method according to claim 14 , wherein the feedback device includes an air-conditioner disposed in a vehicle, and the transmitting of the control signal for operating the feedback device when the positivity index reaches the target positivity index includes:
transmitting, by the controller, at least one of a control signal for the air-conditioner to output a predetermined scent or a control signal for the air-conditioner to output wind of a predetermined mode.
