Description

Technical Field

[0001] This application relates to the field of human-computer interaction technology, and in particular to an interactive device for electroencephalogram (EEG) signals. Background Technology

[0002] Brain-Computer Interface (BCI) technology is an interdisciplinary technology that enables direct interaction between the human brain and electronic devices by collecting and analyzing signals of human brain neural activity. It uses sensors to capture physiological electrical signals generated by brain activity, which are then converted into control commands that can be recognized by computers through signal processing modules. This establishes a human-computer communication channel that does not require the participation of peripheral nerves and muscles. As a new paradigm of human-computer interaction, BCI technology breaks the dependence of traditional interaction methods on limb movements and provides a new path for information transmission between humans and external systems. It has now become a research hotspot in fields such as artificial intelligence, neural engineering, and rehabilitation medicine.

[0003] In related technologies, software programs pre-build virtual interfaces, virtual objects, or virtual environments. Users wear EEG signal acquisition devices, which collect neural activity, convert the neural activity into electrical signals, and transmit them to the software system. The software system analyzes the signal characteristics through built-in algorithms and maps the analysis results to the dynamic parameters of virtual elements. The progress, results, and status of the interaction process are all fed back to the user through the software interface and screens.

[0004] However, the operation results of existing interactive products mainly rely on one-way perception channels such as virtual data, software interface and screen feedback to receive information. The form is monotonous, and it is difficult for users to deeply capture the interaction state during use. This reduces the user's immersive perception of the interaction state during operation, thereby weakening the realism and presence of human-computer interaction and making it difficult to meet users' diverse needs for highly immersive interactive devices. Utility Model Content

[0005] To address the aforementioned problems, this application provides an interactive device for electroencephalogram (EEG) signals.

[0006] The interactive device for electroencephalogram (EEG) signals provided in this application adopts the following technical solution: An interactive device for electroencephalogram (EEG) signals includes a chassis, an interactive mechanism, and a controller. Both the interactive mechanism and the controller are mounted on the chassis. The interactive mechanism includes a physical motion component and a status feedback component. The controller is electrically connected to the physical motion component, the status feedback component, and an EEG signal acquisition device. The physical motion component includes a motion block that is slidably disposed on the chassis. The status feedback component includes an LED strip disposed within the chassis. The controller controls the sliding position of the motion block and the color change of the LED strip based on signals emitted by the EEG signal acquisition device.

[0007] By adopting the above technical solution, the chassis serves as the basic carrier, providing an installation environment for the interactive mechanism and controller. The controller receives user brainwave command signals transmitted by the brainwave signal acquisition device, and simultaneously establishes an electrical connection with the physical motion component and the status feedback component. When the controller receives the brainwave signal, it first analyzes the corresponding interaction requirements and then outputs control commands respectively: on the one hand, it drives the motion block to slide along the preset path of the chassis to the target position, directly converting the virtual brainwave command into a physical displacement that can be directly observed; on the other hand, it controls the light strip to produce corresponding color changes, using light signals to provide users with instant and visual status prompts, forming a multi-channel feedback combination of physical motion and light signals with the physical displacement. This design allows users to perceive the execution effect of commands by seeing the actual movement of the motion block and quickly obtain the interaction status through the color changes of the light strip, thereby establishing a direct and real-time interactive association with virtual objects or the environment, enhancing the user's immersive perception of the interaction process, and greatly improving the realism and presence of human-computer interaction. At the same time, this multi-dimensional feedback mode breaks the limitations of single virtual feedback, can adapt to the user's needs for interactive feedback in different scenarios, and further meets the diverse usage needs of users for highly immersive interactive devices.

[0008] Preferably, the physical motion component further includes a drive unit, and the controller controls the drive unit to drive the motion block to slide on the chassis.

[0009] By adopting the above technical solution, the signals collected by the EEG signal acquisition device received by the controller can be stably converted into the power to drive the sliding of the motion block, ensuring that the sliding action of the motion block responds in a timely manner, allowing the user's EEG commands to be more reliably converted into intuitive physical sliding, further strengthening the mapping from EEG signals to physical movement, enhancing the controllability of operation and the stability of interaction, enhancing the realism and presence of human-computer interaction and the user's immersive perception of the interaction state.

[0010] Preferably, the chassis includes a housing and a cover plate, the cover plate is fitted onto the housing, the moving block is slidably disposed on the cover plate, and the controller and the drive unit are disposed inside the housing.

[0011] By adopting the above technical solution, the cover plate closes the housing to form an accommodating space, housing the controller and drive unit inside the housing, protecting the core components to ensure stable operation and improving the durability of the equipment; at the same time, the moving block slides on the cover plate, placing the moving block in a position that the user can directly observe and touch, making it easier for the user to perceive the physical movement status, enhancing the directness of the interaction, taking into account both the protection of internal components and the interaction needs of external moving blocks, and further improving the reliability of the equipment and the user experience.

[0012] Preferably, an mounting plate is provided inside the housing, and the driving unit includes a first magnetic block and a second magnetic block. The controller drives the first magnetic block to slide on the mounting plate, and the second magnetic block is fixedly connected to the moving block. The first magnetic block and the second magnetic block are attached to the upper and lower surfaces of the cover plate by magnetic attraction.

[0013] By adopting the above technical solution, when the controller drives the first magnetic block to slide along the mounting plate, the first and second magnetic blocks adhere to the upper and lower surfaces of the cover plate respectively by magnetic attraction. This creates a synchronous magnetic transmission relationship between the first and second magnetic blocks. The sliding of the first magnetic block drives the second magnetic block to move synchronously through magnetic attraction, and the moving block fixedly connected to the second magnetic block moves accordingly. This transmission process allows the user's brainwave commands to be converted into controllable sliding of the first magnetic block by the controller, and then transmitted to the moving block via magnetic transmission. This allows the user's brainwave commands to be more reliably converted into intuitive physical sliding, further strengthening the mapping from brainwave signals to physical movement, enhancing the controllability of operation and the stability of interaction, and increasing the realism and presence of human-computer interaction, as well as the user's immersive perception of the interactive state.

[0014] Preferably, a movement area is provided above the cover plate, and the movement block is slidably disposed in the movement area.

[0015] By adopting the above technical solution, the motion area provides a sliding space for the moving block, defining a clear activity area for the moving block. This allows users to intuitively identify the activity space of the moving block, clarify the physical movement range corresponding to the operation, enhance the predictability of the interaction, and further improve the user's perception of the physical motion feedback and the operation experience.

[0016] Preferably, the light strip is disposed on the mounting plate, and the controller and the light strip are electrically connected.

[0017] By adopting the above technical solution, the color change and dynamic effect of the light strip can be controlled in real time by the controller, thereby synchronously mapping with the movement state of the moving block and the color change of the light strip, providing users with a more intuitive interactive perception, further enhancing the realism and presence of human-computer interaction and the user's immersive perception of the interactive state.

[0018] Preferably, the cover plate is provided with a light strip hole, and the position of the light strip hole corresponds to the position of the light strip in the vertical direction.

[0019] By adopting the above technical solution, the layout of the light strip holes corresponds to the position of the light strip, ensuring that the light emitted by the light strip can penetrate the cover plate vertically to form a uniform and concentrated light-emitting area. The brightness and color changes of the light on the cover plate are dynamically linked with the movement trajectory of the moving block to obtain a more intuitive and immersive interactive experience.

[0020] Preferably, the bottom of the housing is provided with multiple support seats, which are fixedly connected to the housing.

[0021] By adopting the above technical solution, multiple support bases are fixedly connected to the housing, which effectively improves the structural stability and load-bearing capacity of the equipment, reduces the risk of equipment shaking or tilting, and ensures the high-precision operation of the status feedback component and the physical motion component.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The physical motion component and controller are installed in the chassis. The controller is electrically connected to the physical motion component, the status feedback component, and the EEG signal acquisition device. It can control the movement of the physical motion component and the feedback information of the status feedback component according to the EEG signal. This realizes the transformation of operation results from virtual data feedback to a combination of physical motion and status feedback in a multi-channel status prompt. It can enhance the user's immersive perception, improve the realism and presence of human-computer interaction, and meet the diverse needs of users for highly immersive interactive devices. 2. The controller drives the motion block to slide on the chassis, converting the signals from the EEG signal acquisition device into a motion block that can be intuitively perceived. Through this specific physical motion, users can intuitively feel the physical action corresponding to the operation, making virtual interaction and real physical motion more closely integrated, enhancing the intuitiveness and realism of operation feedback, thereby improving the real experience, immersion, realism and presence of human-computer interaction, as well as the user's immersive perception of the interaction state. 3. The controller is electrically connected to the light strip. The light strip serves as visual feedback. The color change and dynamic effects of the light strip can be controlled in real time by the controller and synchronously mapped with the motion state of the moving block. This provides users with a more intuitive interactive perception and further enhances the realism and immersion of human-computer interaction, as well as the user's immersive perception of the interactive state.

[0029] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0030] This application discloses an interactive device for electroencephalogram (EEG) signals.

[0031] Reference Figure 1 An interactive device for EEG signals includes a chassis 1, an interactive mechanism, and a controller 5. The chassis 1 is used to install the interactive mechanism and the controller 5. The interactive mechanism includes a physical motion component 2 and a status feedback component 3. The controller 5 is electrically connected to the physical motion component 2 and the EEG signal acquisition device. The controller 5 can control the movement of the physical motion component 2 and the status feedback component 3 to provide status information based on the signals emitted by the EEG signal acquisition device, allowing users to obtain a more realistic interactive experience through physical motion and status feedback, thereby enhancing the realism and immersion of human-computer interaction.

[0032] In this embodiment, it should be noted that the device is configured for dual-user collaborative application. The controller 5 and the EEG signal acquisition device are wirelessly connected. The EEG signal acquisition device consists of a first EEG instrument and a second EEG instrument. The first user wears the first EEG instrument, and the second user wears the second EEG instrument. Both the first and second EEG instruments are wirelessly connected to the controller 5, facilitating free movement for both users and ensuring stable transmission of EEG data. The controller 5 receives the first EEG signal transmitted by the first EEG instrument and the second EEG signal transmitted by the second EEG instrument. Upon receiving the signal, the computer program built into the controller 5 initiates a specialized processing flow, using a preset algorithm to analyze, extract features, and perform collaborative logic judgment on the two sets of EEG signals, providing data support for the generation of subsequent control commands. The core logic of this computer program is existing technology and will not be elaborated upon here.

[0033] Reference Figure 2 Specifically, the chassis 1 includes a housing 11 and a cover plate 12, which form a certain internal space. Multiple support seats 4 are provided at the bottom of the housing 11. In this embodiment, four support seats 4 are provided. The four support seats 4 are evenly fixed at the bottom of the housing 11, which effectively improves the structural stability and load-bearing capacity of the equipment, reduces the risk of equipment shaking or tilting, and ensures the high-precision operation of the status feedback component 3 and the physical motion component 2.

[0034] Furthermore, the physical motion component 2 includes a motion block 21 and a drive unit 22. The motion block 21 is set as a rectangular block, and a motion area 122 is provided on the upper surface of the cover plate 12. The motion block 21 is slidably set in the motion area 122. The motion area 122 provides a clear activity area for the motion block 21, ensuring the standardization and orderliness of the motion, and allowing users to intuitively identify the activity space of the motion block 21, clarify the physical motion category corresponding to the operation, enhance the predictability of the interaction, and further improve the user's perception clarity and operation experience of physical motion feedback.

[0035] Reference Figure 3Meanwhile, a mounting plate 13 is provided inside the housing 11, and the side wall of the mounting plate 13 is fixed to the inner side wall of the housing 11. The drive unit 22 includes a drive motor 221, a carrier bar 222, a drive wheel 223, a driven wheel 224, a belt 225, a movable block 226, a housing 227, and a first magnetic block 228. The drive motor 221, drive wheel 223, driven wheel 224, belt 225, movable block 226, and first magnetic block 228 are all mounted on the mounting plate 13. 225 is fitted onto the driving wheel 223 and the driven wheel 224. There are two housings 227. The driving wheel 223 and the driven wheel 224 are respectively located in the two housings 227, and the driving wheel 223 and the driven wheel 224 are rotated and supported in the two housings 227. The carrier bar 222 is located in the belt 225. The two ends of the carrier bar 222 are respectively fixedly connected to the two housings 227. The movable block 226 is fixed on the belt 225, and the first magnetic block 228 is fixed on the movable block 226.

[0036] Furthermore, the drive unit 22 also includes a second magnetic block 229, which is disposed in the motion area 122. The motion block 21 is fixedly disposed on the upper surface of the second magnetic block 229. When the cover plate 12 is closed on the housing 11, the first magnetic block 228 and the second magnetic block 229 abut against the upper and lower surfaces of the cover plate 12 respectively, so that the first magnetic block 228 and the second magnetic block 229 magnetically engage. The controller 5 is electrically connected to the drive motor 221.

[0037] This demonstrates that the mounting plate 13 provides a unified and stable mounting reference for all components of the drive unit 22, including the drive motor 221, the drive wheel 223, and the driven wheel 224. Since the controller 5 is electrically connected to the EEG signal acquisition device, and the EEG signal acquisition device is electrically connected to the drive motor 221, the signal received by the EEG signal acquisition device can be converted into a drive command and transmitted to the drive motor 221. After the drive motor 221 starts, it drives the drive wheel 223 to rotate, which in turn causes the belt 225 sleeved on the drive wheel 223 and the driven wheel 224 to rotate accordingly.

[0038] Furthermore, the rotation of the belt 225 drives the movable block 226 fixed on the belt 225 to move synchronously. The movable block 226 then drives the first magnetic block 228 fixed to the movable block 226 to translate. Since the first magnetic block 228 and the second magnetic block 229 abut against the upper and lower surfaces of the cover plate 12 respectively, and the first magnetic block 228 and the second magnetic block 229 are magnetically attracted, the first magnetic block 228 then drives the second magnetic block 229 above the cover plate 12 to move through the magnetic attraction force. Since the moving block 21 is fixedly connected to the upper surface of the second magnetic block 229, the moving block 21 moves further in the moving area 122. At the same time, the two ends of the carrier strip 222 are fixed to the two housings 227, forming a stable load on the movable block 226. Furthermore, the above process transforms the signals collected by the EEG signal acquisition device into the intuitively perceptible sliding displacement of the motion block 21. This specific form of physical movement allows users to intuitively feel the physical action corresponding to the operation, making virtual interaction and real physical movement more closely integrated, enhancing the intuitiveness and realism of the operation feedback, further improving the real experience and immersion of human-computer interaction, and strengthening the user's perception of the interaction state.

[0039] Furthermore, in this embodiment, the controller 5 maintains a real-time electrical connection with the EEG signal acquisition device and the drive motor 221. Every second, the controller 5 synchronously extracts the attention EEG parameters of the first user and the second user from the EEG signal acquisition device and immediately calculates the difference between the two sets of parameters.

[0040] Furthermore, the calculated difference becomes the direct basis for the action of the drive motor 221. The controller 5 will accurately convert the difference into the specific control parameters of the drive motor 221. When the difference is 0, it means that the focus of the first user and the second user is at the same level. At this time, the controller 5 sends a stop command to the drive motor 221, and the drive motor 221 stops rotating. The first magnetic block 228 linked with it stops displacing, and the second magnetic block 229, which is subjected to the magnetic attraction of the first magnetic block 228, also stops. The moving block 21 thus maintains its current position.

[0041] Furthermore, if the difference is greater than 0, meaning the first user's focus is higher than the second user's, the controller 5 sends a clockwise rotation command to the drive motor 221. After the drive motor 221 starts clockwise, it drives the drive wheel 223 to rotate. This further drives the driven wheel 224 and the belt 225 to move the movable block 226 and the first magnetic block 228. The first magnetic block 228 uses magnetic attraction to pull the second magnetic block 229 to slide synchronously in the direction corresponding to the rotation of the drive motor 221, and the movable block 21 also moves in that direction.

[0042] Meanwhile, when the difference is less than 0, that is, when the first user's focus is lower than that of the second user, the controller 5 issues a counterclockwise rotation command, driving the motor 221 to run in the opposite direction. Similarly, the transmission system drives the first magnetic block 228 to move in the opposite direction, and then the magnetic attraction force drives the second magnetic block 229 and the moving block 21 to slide in the direction corresponding to the reverse rotation of the drive motor 221.

[0043] In addition, a motion area 122 is provided above the cover plate 12, and the motion block 21 is slidably positioned in the motion area 122, which defines a clear activity area for the motion block 21. This allows users to intuitively identify the activity space of the motion block 21, clarify the physical movement range corresponding to the operation, enhance the predictability of the interaction, and further improve the user's perception of the physical movement feedback and the operation experience.

[0044] On the other hand, the status feedback component 3 is provided in two sets. The two sets of status feedback components 3 are installed on the mounting plate 13 and at both ends of the drive unit 22. The status feedback component 3 includes a light strip 31 and a boss 32. The boss 32 is fixed on the mounting plate 13. The upper surface of the boss 32 is provided with a light strip groove 321, and the light strip 31 is built into the light strip groove 321.

[0045] Reference Figure 5 Furthermore, the light strip 31 includes two docking terminals 311, a substrate 312, and multiple LED beads 313. Both the docking terminals 311 and the LED beads 313 are disposed on the substrate 312. The docking terminals 311 are disposed at both ends of the substrate 312. The multiple LED beads 313 are disposed between the two docking terminals 311 along the length direction of the substrate 312. The docking terminals 311 are electrically connected to the LED beads 313. In addition, light strip holes 121 are provided on both sides of the cover plate 12. The positions of the light strip holes 121 and the positions of the light strip 31 correspond in the vertical direction.

[0046] This demonstrates that the layout of the light strip hole 121 corresponds precisely to the position of the light strip 31, ensuring that the light emitted by the light strip 31 can penetrate the cover plate 12 vertically to form a uniform and concentrated light-emitting area.

[0047] Furthermore, the controller 5 is electrically connected to the docking terminal 311, which converts the signals received by the EEG signal acquisition device into drive commands and transmits them to the docking terminal 311. This, in turn, controls the LED beads 313 to display different colors, with color changes reflecting the user's brain state in real time. The two sets of light strips 31 correspond to the brain states of the first and second users, allowing both individuals to intuitively and instantly see their current EEG parameter status. Simultaneously, the brightness and color changes of the lights on the cover plate 12 are dynamically linked to the movement trajectory of the motion block 21. This design, which transforms EEG signals into concrete visual feedback, not only enhances the clarity of perception of brain activity states but also further improves the intuitiveness and immersion of human-computer interaction through the coordinated interaction of light and shadow with movement, providing users with a richer interactive experience. The implementation principle of an interactive device for electroencephalogram (EEG) signals according to an embodiment of this application is as follows: The first user and the second user wear the first EEG device and the second EEG device respectively. The first EEG device and the second EEG device communicate with the controller 5 through a wireless connection, which allows for free movement and stable transmission of EEG data. The controller 5 receives and processes the first and second EEG signals transmitted by the first EEG device and the second EEG device, extracts the attention parameters and calculates the difference, and at the same time converts the signals into instructions and transmits them to the physical motion component 2 and the status feedback component 3 respectively. The controller 5 controls the drive motor 221 on the mounting plate 13 inside the housing 11 based on the difference in attention. When the difference is 0, the motor stops, and the movable block 226 and the first magnetic block 228, which are linked by the drive wheel 223, the driven wheel 224, and the belt 225, remain stationary. The movable block 21, which is fixed to the second magnetic block 229 in the motion area 122 of the cover plate 12, also remains stationary. When the difference is greater than 0, it indicates that the first user has a higher level of attention. The drive motor 221 rotates clockwise, driving the drive wheel 223 and the belt 225 to rotate, causing the movable block 226 and the first magnetic block 228, which are fixed to the belt 225, to move. With the help of magnetic attraction, the second magnetic block 229 and the movable block 21 above the cover plate 12 slide in the corresponding direction in the motion area 122. When the difference is less than 0, the motor rotates counterclockwise, indicating that the second user has a higher level of attention. The movable block 21 slides in the opposite direction. The stable support of the carrier bar 222 on the movable block 226 ensures smooth transmission, converting the EEG signal into intuitive physical movement and enhancing the realism of the interaction. Within the LED strip grooves 321 of the protrusions 32 at both ends of the mounting plate 13, the LED strip 31 receives commands from the controller 5 through the docking terminal 311. The LED beads 313 on the substrate 312 display different colors according to the user's EEG state. The two sets of LED strips 31 correspond to the first user and the second user respectively, enabling the first user and the second user to intuitively perceive their own EEG parameter state in real time, realizing the conversion of EEG signals into visual feedback, further enhancing the interactive immersion. The entire process forms a closed loop from EEG acquisition and processing to physical movement and state feedback, continuously enhancing the realism and presence of human-computer interaction.

[0048] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
