Brain stimulation device and brain stimulation system

1 . A brain stimulation system comprising:

a wearable electronic device including a display, a biometric information acquisition unit, and a first processor; and

a brain stimulation device having at least one area configured to be attached to a body of a user and apply brain stimulation to the user such that the user feels a smoking sensation, the brain stimulation corresponding to brain waves changed by smoking,

wherein the biometric information acquisition unit detects biometric information of the user that changes in response to the brain stimulation, and

the first processor controls the display to display one of a virtual reality image and an augmented reality image including the detected biometric information of the user.

2 . The brain stimulation system of claim 1 , wherein the biometric information acquisition unit includes at least one of a heart rate measurement sensor, an electrocardiogram measurement sensor, a body temperature measurement sensor, a sweat measurement sensor, and an oxygen saturation measurement sensor.

3 . The brain stimulation system of claim 1 , wherein the first processor controls the display to display one of a virtual reality image and an augmented reality image including a smoking progress rate based on a change in the biometric information.

4 . The brain stimulation system of claim 1 , wherein the first processor controls the display to display a virtual reality image or an augmented reality image including a warning message to stop using the brain stimulation device when the biometric information is greater than or equal to a preset threshold.

5 . The brain stimulation system of claim 1 , wherein the brain stimulation device comprises:

a housing including an accommodation space for accommodating an article;

an output unit configured to out a current; and

a second processor configured to control the output unit to provide a current corresponding to the article to the body of the user.

6 . The brain stimulation system of claim 5 , wherein the article is a cigarette-shaped memory stick including a memory in which identification information is stored.

7 . The brain stimulation system of claim 6 , wherein the identification information includes a type of the article and a number of available uses of the article.

8 . The brain stimulation system of claim 5 , wherein

the second processor applies a current corresponding to a first current profile to the body of the user through the output unit such that brain stimulation corresponding to a first brain stimulation profile is applied to the user when it is detected that a first article is accommodated in the accommodation space, and

the second processor applies a current corresponding to a second current profile to the body of the user through the output unit such that brain stimulation corresponding to a second brain stimulation profile is applied to the user when it is detected that a second article different from the first article is accommodated in the accommodation space.

9 . The brain stimulation system of claim 8 , wherein the first processor displays one of a virtual reality image and an augmented reality image in which cigarette smoke is generated, and controls the display to change an image of at least one of a color, an amount, and a shape of the cigarette smoke depending on a type of the article.

10 . The brain stimulation system of claim 8 , wherein the first processor displays one of a preset virtual reality image for stress relief and a preset augmented reality image for stress relief on the display when the biometric information corresponds to a preset stress range.

11 . The brain stimulation system of claim 10 , wherein the one of the preset virtual reality image for stress relief and the preset augmented reality image for stress relief includes an image of a natural environment or a certain place selected for stress relief of the user.

12 . The brain stimulation system of claim 11 , further comprising a sound reproduction device,

wherein the first processor controls the sound reproduction device to output a sound corresponding to the one of the preset virtual reality image for stress relief and the preset augmented reality image for stress relief.

13 . The brain stimulation system of claim 1 , wherein

the wearable electronic device includes a first communication unit, and

the brain stimulation device includes a second communication unit for communicating with the first communication unit.

14 . A brain stimulation device comprising:

a display;

a biometric information acquisition unit;

an accommodation space configured to accommodate an article;

an output unit having at least one area configured to be attached to a body of a user and apply a current corresponding to the article to the body of the user to apply brain stimulation to the user such that the user feels a smoking sensation, the brain stimulation corresponding to brain waves changed by smoking; and

a processor configured to control operations of the display, the biometric information acquisition unit, and the output unit,

wherein the biometric information acquisition unit detects biometric information of the user that changes in response to the brain stimulation, and

the processor controls the display to display one of a virtual reality image and an augmented reality image including the detected biometric information of the user.

15 . The brain stimulation device of claim 14 , wherein the biometric information acquisition unit includes at least one of a heart rate measurement sensor, an electrocardiogram measurement sensor, a body temperature measurement sensor, a sweat measurement sensor, and an oxygen saturation measurement sensor.
