The lighting unit 232 may provide visible light or infrared light. The lighting unit 232 may be disposed in front of the learner.

The control unit 300 may determine the plane coordinates (XY coordinates) of the user's head from the image input from the first camera 170 . If the longitudinal direction of the learner's head is defined as the X-axis, the height direction of the head as the Y-axis, and the depth direction of the head as the Z-axis, the control unit 300 receives the image input from the first camera 170. , the XY coordinates of the learner's head can be determined. In addition, the control unit 300 can determine the learner's Z coordinate from the image input from the second camera 200 . For example, the control unit 300 can determine the Z coordinate of the learner's head by detecting the distance between the learner's head and the back of the chair 150 from the learner's top image input from the second camera 200. .

The control unit 300 may measure the angle of the learner's head based on a virtual Z-axis defined in the vertical direction. Here, the virtual Z-axis may be set to pass through the user's upper body in a vertical direction.

When the learner's head is within the reference angle with respect to the Z-axis, the controller 300 performs normal control according to the learning environment set by the learner.

However, when the learner's head exceeds the reference angle with respect to the Z-axis, the control unit 300 determines that the learner is in a sleep state or sleepy state, and moves within the study room 100 through the drive unit 234. By driving the components, it is possible to improve the learner's concentration.

Specifically, the driving unit 234 sets the temperature of the air discharged from the air conditioner 180 low and increases the flow rate of the air discharged from the air conditioner 180 . Also, the driver 234 increases the amount of light of the lighting device 190 . Also, the driving unit 234 increases the volume of sound output from the monitor 160 . In addition, the driving unit 234 transmits the learner's image captured through the first camera 170 to the management server 400 or the manager terminal 600 . In addition, the driving unit 234 drives the seat adjustment unit of the chair 150 to set the angle between the backrest and the seating surface to be perpendicular.

The study room 100 may communicate with the manager server 400 and the manager terminal 600 . The manager server 400 may be a server operated by a manager who manages the study room 100 . The manager terminal 600 may be a terminal possessed by a manager who manages the study room 100 . The manager terminal 600 may also include a guardian terminal of a learner learning in the study room 100 . Accordingly, information about the learner's learning progress, learning attitude, and learning time can be transmitted to the manager server 400 and the manager terminal 600 . In addition, information about the learner's learning progress, learning attitude, and learning time is stored in the database 500, so that each individual's learning situation can be converted into data for each unique ID.

Based on the result detected by the door detection sensor, the study room to control the operation of the lighting device through the control unit.
According to claim 4,
The operation of the lighting device,
A study room driven in a first mode in which the LED chip for lighting emits light or in a second mode in which the LED chip for sterilization emits light.
According to claim 3,
The air conditioner includes a filter disposed on an air flow path, and a light source for irradiating UV light to the filter,
The air conditioner includes a cooling/heating mode for discharging heat-exchanged air into the study space and a sterilization mode for sterilizing the filter through the light source.
According to claim 3,
In the study space,
A first camera disposed above the monitor in the space within the frame and photographing the learner; and
Based on the virtual Z-axis, a body detection sensor for measuring the angle of the learner's head;
The study room is more equipped with.
According to claim 7,
The body detection sensor includes a second camera disposed on the ceiling surface of the study room to obtain an image of the learner's upper face,
The body detection sensor determines the XY coordinates of the learner's head from the image input from the first camera, and determines the Z coordinate of the learner from the image input from the second camera.
According to claim 7,
The virtual Z-axis is set to penetrate the upper body of the user in the vertical direction,
Based on the result detected by the body detection sensor, when the learner's head exceeds the reference angle with respect to the virtual Z-axis, the temperature of the air discharged from the air conditioner is lowered, and the air discharged from the air conditioner is lowered. The study room, in which the flow rate of is increased, the amount of light of the lighting device is increased, the volume of sound output from the monitor is increased, and the learner's image captured through the first camera is transmitted to a manager terminal.
