Abstract

A vehicle may include: a feedback device; a bio-signal sensor configured to measure a bio-signal of a user; and a controller operatively coupled to the feedback device and the bio-signal sensor, the controller including a memory configured to store at least one program instruction and processor configured to execute the at least one program instruction. The controller may be configured to: determine information characterizing a current emotional state of the user based on the bio-signal; calculate, based on a difference value between the current emotional state and a target emotional state, an operation ratio between a first mode for controlling operation of the feedback device to decrease a degree of excitability of the user and a second mode for controlling the operation of the feedback device to increase a degree of positivity of the user; and control the operation of the feedback device for a predetermined time based on the operation ratio.

First claim

What is claimed is:

1. A vehicle comprising:
a feedback device;
a bio-signal sensor configured to measure a bio-signal of a user; and
a controller configured to:
determine an information of a current emotional state of the user based on the bio-signal;
extract at least one emotion factor that affects the current emotional state;
determine, based on a difference value between the current emotional state and a target emotional state, an operation ratio between a first mode for controlling the feedback device to decrease an emotion factor corresponding to a degree of excitability of the user among the at least one emotion factor and a second mode for controlling the feedback device to increase an emotion factor corresponding to a degree of positivity of the user among the at least one emotion factor; and
control the feedback device for a predetermined time based on the operation ratio,
calculate a first difference value between the degree of excitability for the current emotional state and the degree of excitability for the target emotional state,
calculate a second difference value between the degree of positivity for the current emotional state and the degree of positivity for the target emotional state, and
calculate the operation ratio between the first mode and the second mode as equivalent to a ratio between the first difference value and the second difference value.

2. The vehicle according to claim 1 , wherein the controller is configured to control the feedback device to output at least one of a sound, an image, or a vibration having a frequency corresponding to a target breathing cycle or a target heartbeat cycle in the first mode.

3. The vehicle according to claim 1 , wherein the controller is configured to control the feedback device to output at least one of perfume or wind that decreases the emotion factor corresponding to the degree of excitability in the first mode.

4. The vehicle according to claim 1 , wherein the controller is configured to control the feedback device to output an image of a color that decreases the emotion factor corresponding to the degree of excitability in the first mode.

5. The vehicle according to claim 1 , wherein the controller is configured to control the feedback device to output at least one of a sound that increases the emotion factor corresponding to the degree of positivity, a vibration having a frequency corresponding to the sound, or an image having a frequency corresponding to the sound in the second mode.

6. The vehicle according to claim 1 , wherein the controller is configured to control the feedback device to output at least one of perfume or wind that increases the emotion factor corresponding to the degree of positivity in the second mode.

7. The vehicle according to claim 1 , wherein the controller is configured to control the feedback device to output an image of a color that increases the emotion factor corresponding to the degree of positivity in the second mode.

8. The vehicle according to claim 1 , further comprising:
a camera configured to obtain image data of the user,
wherein the controller is configured to determine information about the user's current emotional state based on at least one of the image data or the bio-signal.

9. The vehicle according to claim 1 , further comprising:
an inputter configured to receive information about the target emotional state from the user.

10. A method for controlling a vehicle, the vehicle including a feedback device, and a bio-signal sensor configured to measure a bio-signal of a user, the method comprising:
determining an information of a current emotional state of the user based on the bio-signal;
extracting at least one emotion factor that affects the current emotional state;
determining, based on a difference value between the current emotional state and a target emotional state, an operation ratio between a first mode for controlling the feedback device to decrease an emotion factor corresponding to a degree of excitability of the user among the at least one emotion factor and a second mode for controlling the feedback device to increase an emotion factor corresponding to a degree of positivity of the user among the at least one emotion factor; and
controlling the feedback device for a predetermined time based on the operation ratio,
wherein determining the operation value comprises:
calculating a first difference value between the degree of excitability for the current emotional state and the degree of excitability for the target emotional state,
calculating a second difference value between the degree of positivity for the current emotional state and the degree of positivity for the target emotional state, and
calculating the operation ratio between the first mode and the second mode as equivalent to a ratio between the first difference value and the second difference value.

11. The method according to claim 10 , wherein the controlling of the feedback device comprises:
controlling the feedback device to output at least one of a sound, an image, or a vibration having a frequency corresponding to a target breathing cycle or a target heartbeat cycle in the first mode.

12. The method according to claim 10 , wherein the controlling of the feedback device comprises:
controlling the feedback device to output at least one of perfume or wind that decreases the emotion factor corresponding to the degree of excitability in the first mode.

13. The method according to claim 10 , wherein the controlling of the feedback device comprises:
controlling the feedback device to output an image of a color that decreases the emotion factor corresponding to the degree of excitability in the first mode.

14. The method according to claim 10 , wherein the controlling of the feedback device comprises:
controlling the feedback device to output at least one of a sound that increases the emotion factor corresponding to the degree of positivity, a vibration having a frequency corresponding to the sound, or an image having a frequency corresponding to the sound in the second mode.

15. The method according to claim 10 , wherein the controlling of the feedback device comprises:
controlling the feedback device to output at least one of perfume or wind that increases the emotion factor corresponding to the degree of positivity in the second mode.

16. The method according to claim 10 , wherein the controlling of the feedback device comprises:
controlling the feedback device to output an image of a color that increases the emotion factor corresponding to the degree of positivity in the second mode.

17. The method according to claim 10 ,
wherein the vehicle further comprises a camera configured to obtain image data of the user, and
wherein the controlling of the feedback device comprises:
determining information about the user's current emotional state based on at least one of the image data or the bio-signal.

18. The method according to claim 10 , wherein the vehicle further comprises an inputter configured to receive information about the target emotional state from the user.
