The EEG signals generated by brain activities are an effective presentation of neuronal activities. Brain-computer interface refers to a new external information exchange and control technology established between the human brain and electronic devices that does not rely on conventional brain information output pathways. The brain-computer interface can receive and process different EEG signals generated when people perform different physiological and psychological activities.

[0032] When in use, the EEG signal acquisition cap 1 adopts a brain-computer interface system, which adopts a non-invasive EEG signal acquisition method, and the display device 2 provides virtual reality scenes, augmented reality scenes, virtual reality and augmented reality combined scenes, and even ordinary audio-visual scenes. The EEG signal processor completes the acquisition of EEG signals, and its acquisition method is wireless or wired acquisition. The display device 2 is connected to the external scene providing device by wire or wireless to obtain superposition, assistance, virtual construction and other scenes. The drive control host is connected to the EEG signal processor to realize the output and execution of EEG signal instructions.

[0033] The execution unit consists of a wearable garment 3 and an auxiliary seat mechanism. The user can be a healthy person or other people with limited limb movement. The wearable garment 3 is available in different sizes and is made of a double-layer structure to ensure effective protection of the circuit and pipeline connection parts and improve the safety factor when the product is used. The far-infrared electric heater provides local body heat source feedback in the application scenario, the water-cooled circulation pipeline provides body feedback in the cold environment in the application scenario, and the vibrating low-frequency electric pulser provides tactile feedback and neural tactile feedback in the application scenario. The control interface 14 and the liquid inlet check valve 12 and the liquid outlet check valve 13 of the water-cooled circulation pipeline 11 are both set at the waist position to facilitate connection with external pipelines and lines. When taking a standing immersive experience, feedback mechanisms such as lines and pipelines are also set on the back of the wearable garment. When taking a sitting immersive experience, because the back of the user needs to contact the seat, feedback mechanisms such as lines and pipelines are not set.

[0034] The rotating platform 20 provides the viewing angle and action steering operation of the use scene in the sitting state, and the overall vibration base implements the overall vibration operation of the smart seat 22, and the vibration includes up and down vibration, left and right vibration, and front and back vibration. The head vibration receiving pad 23, the shoulder and back vibration receiving pad 24, the upper limb vibration receiving pad 27, the lower limb vibration receiving pad 25 and the foot receiving vibration limit groove 26 provide local tactile vibration operation for the user. The vibration feedback comes from the EEG signal instructions generated by the user after the scene plot and audio-visual collection in the virtual scene. When the user is stimulated by the scene in the scene, a corresponding EEG signal will be generated. The external EEG signal processor will analyze the characteristics of the EEG signal, and after processing, the corresponding components of the corresponding parts will be driven to generate different stimulation means, and the corresponding auxiliary stimulation will be implemented on the local or overall parts of the body, thereby providing stimulation feedback corresponding to the application scene.

[0035] At the same time, in addition to the heat sensation, cold sensation, pressure vibration, low-frequency electric pulse stimulation of the worn clothes, and the local vibration and overall rotation and vibration of the auxiliary seat, this product is also provided with a unique structure of a rotating immersive arc guard plate 29 to assist the user in stimulation feedback in the application scenario. When thermal feedback is implemented, this product is provided with a hot air outlet 30. The hot air blown out by the hot and cold air blower 39, combined with the thermal feedback of the worn clothes, further improves the realism. When the user imagines that the external environment is hot in the application scenario, the EEG signal can be collected and processed to drive the far-infrared electric heating plate of the wearable device to heat up and then provide thermal feedback. At the same time, the hot air outlet 30 will blow out hot air accordingly, allowing the user to have an immersive sense of being in the scene. This sense of immersion can further stimulate the user's brain to generate corresponding EEG signals, forming a "EEG signal formation-EEG signal processing-EEG signal execution drive-user body stimulation feedback-EEG signal enhancement formation" cyclic stimulation system.

[0036] The cold water tank 33 has two functions when in use. One is to connect the cold water in the cold water tank 33 to the liquid inlet check valve 12 through the water inlet pipe 36 through the three-way water pump 37, and to deliver the cold water pressure to the water cooling circulation pipeline, and to return the water from the liquid outlet check valve 13 to the cold water tank 33 through the return pipe 35. This process provides users with a real touch in cold application scenarios. When the user is in a cold environment application scenario, the brain will imagine the state of the body when it is cold. After the EEG signal is collected and processed, the cold treatment module starts to run. In addition to being realized through the water cooling circulation pipeline 11 set in the wearable clothes 3, the cold treatment module also implements auxiliary stimulation through the atomized water nozzle 32 set on the rotating immersed arc guard plate 29. And it can cooperate with the hot air pipe 42 to blow out cold air to form a cold stimulation feedback. In addition, the atomizing water nozzle 32 also simulates rainy and snowy weather in the application scenario, providing tactile stimulation for the user, further improving the strength of the EEG signal, improving the collection efficiency, further realizing the formation of instructions corresponding to the stimulation, and improving the strength and collection efficiency of the EEG signal.

[0037] During the use of the application scenarios of the present invention, EEG signals are collected using a multi-lead collection device. The application scenarios should focus on relaxed and pleasant or highly focused scenes in virtual reality scenes, augmented reality scenes, fused reality scenes or audio-visual scenes, which is conducive to the collection of EEG signals and efficient processing of signals.

[0038] Far-infrared electric heating sheets are distributed in multiple parts of the body, and adopt far-infrared heating. Because the carbon fiber material used is not as easy to overheat as traditional metal electric heating wires, it reduces safety risks such as fire. The heating is a short-term heating method, and it is not easy to use it for too long in hot scenes. At the same time, local ventilation design should be adopted at the locations of the installed chest electric heating sheet 6, abdomen electric heating sheet 10 and thigh front electric heating sheet 16, and the heating temperature should be controlled. While the user feels the change in heat, the fireproof insulation design of the clothes worn can be carried out to ensure safety during the period.

[0039] The structure of the vibration-type low-frequency electric pulse device adopts a two-layer design. The bottom layer close to the skin uses low-frequency electric pulses to stimulate local parts of the human body, which can excite nerve and muscle tissue and promote local blood circulation. In order to improve the safety of this product, the low-frequency electric pulses are in the form of low voltage and low frequency to avoid discomfort, and the action time is controlled within 1 second. The upper layer is a vibration mechanism equipped with a small eccentric vibration motor. When running, it can implement local vibration of the contact body part alone, and can also provide low-frequency electric pulse stimulation operations of the contact body part, thereby implementing feedback on the instructions of the brain electrical signal.

[0040] The auxiliary seat mechanism of the present invention can be used alone or in conjunction with wearable clothing 3, providing different feedback systems, increasing the scope of use of the product, and providing support for people with different needs. The seat controller is connected to the drive control host to execute the instructions of the EEG signal and quickly implement online feedback to provide users with online feedback operations such as vibration, seat rotation, facial hot air, facial cold air, and facial water mist. Together with the feedback stimulation obtained in the use scenario, it improves the user's sense of space, participation, reality, and control in the application scenario.

[0041] The rotating immersed arc-shaped guard plate 29 adopts a rotating mechanism, which is in an upwardly rotated and open state before use. After the user is in place, the guard plate rotating motor drives the guard plate rotating shaft to rotate, and rotates the rotating immersed arc-shaped guard plate 29 to the user's face position. The user can put on the wearable device 3 and sit in place, or put on ordinary clothes and sit in place. The hot air, cold air and spray provided by the rotating immersed arc-shaped guard plate 29 are aimed at the user's facial position. Because other parts are blocked by clothes, the facial position can be better stimulated and feedback can be formed. The water mist spray stimulation operation uses pure water that is harmless to the human body, and controls the atomization particle size to ensure its safety. The spray time is controlled within 1 second. The electric refrigerator cooperates with the external radiator to reduce the water temperature in the cold water tank 33, and the water temperature should not be lower than 5 degrees Celsius.

[0042] The hot and cold air blower 39 adopts an isolation chamber structure, and the two sides of the hot and cold air isolation plate are independent cold air chambers and hot air chambers. At the same time, the hot and cold air chamber partition 53 is made of heat-insulating and cold-insulating materials, which can implement temperature isolation for the cavities on both sides. Hot air is formed in the hot air chamber. After the air is heated by the electric heating wire, it is sucked into the low-speed exhaust fan 48 at the top of the first solenoid valve 46 after it is opened, and finally output from the hot air outlet 30 through the hot air pipe 42. Cold air is formed in the cold air chamber. After the air is cooled by the electric refrigeration end 50, it is sucked into the low-speed exhaust fan 48 at the top of the second solenoid valve 49 after it is opened, and finally output from the cold air outlet 31 through the cold air pipe 41.

[0043] Example 1: Figure 1 , 2 As shown in FIG. 6 , when the present embodiment is in operation, the immersive experience is implemented only in the form of wearing a set of clothes. After the user wears the set of clothes 3 , he takes a standing position and wears the electric signal collection cap 1 and the display device 2 . When receiving visual and auditory stimulation from virtual reality scenes, augmented reality scenes, fused virtual scenes or audio-visual scenes, the user generates corresponding EEG signals. The EEG signal is collected by wearing an EEG signal collection cap 1 and amplified, and finally classified and processed by an EEG signal processor. After the EEG signal is classified and processed, an instruction is sent to the drive control host, which is connected to the control interface 14 through a wire, and the classified EEG signal is converted into control of corresponding components on the wearable clothing 3, local heating is implemented by driving a far-infrared electric heater, local pressure vibration and low-frequency pulse emission are implemented by driving a vibrating low-frequency electric pulser, and cold water circulation is implemented through a water-cooled circulation pipe 11 to cool down, thereby implementing corresponding external stimulation to the human body. The stimulation form and stimulation site come from the EEG signal instruction.
