Description

Technical Field

[0001] The present invention belongs to the technical field of smart home and metaverse interaction, and specifically relates to an immersive sofa system that integrates environmental control, somatosensory feedback and physiological monitoring, and realizes full-body immersive mapping of virtual scenes through multimodal sensory collaboration technology (including touch, vestibular sense, smell, and hearing). Background Art

[0002] The existing technology has the following defects: The first is sensory fragmentation: traditional somatosensory devices (such as 4D cinema chairs) only support simple feedback such as vibration and tilt, and lack the integration of environmental elements (smell, wind field) and physical contact interaction. The second is space limitation: neither game console controllers nor other peripherals with vibration feedback can adapt to the sofa form, and the electric massage chairs with vibration massage function on the market cannot connect the game and the metaverse to achieve real-time somatosensory interaction. The third is the lack of physiological safety: high-intensity somatosensory equipment lacks the ability to dynamically monitor the user's physiological state and emergency braking.

[0003] The present invention proposes a systematic solution, integrating a transparent cover microenvironment generator, a full-body tactile feedback device and intelligent safety control into the sofa body to achieve the "five senses synaesthesia" of the metaverse scene. Summary of the invention

[0004] The system architecture of the Metaverse multimodal immersive sofa includes hardware consisting of an enhanced sofa body and a transparent cover system, as well as functional module interaction logic including dynamic somatosensory mapping and environment-somatosensory collaboration.

[0005] The structure of the enhanced sofa body is divided into surface layer, middle layer and bottom layer. Surface layer: high elastic memory foam + conductive fabric (embedded with pressure sensor array, accuracy ±5%); middle layer: trunk area: 6 groups of pneumatic compression units (pressure 0-100kPa adjustable), limb area: 8 servo motor driven stretch belts (tension 0-200N, stroke 50cm), base: 4-degree-of-freedom motion platform (pitch ±15°, roll ±10°, lift 20cm); bottom layer: surround sound speakers (7.1.4 channels, including seat bone conduction unit); environmental module cabin (integrated ultrasonic atomizer, semiconductor cooling sheet, odor capsule cabin).

[0006] The transparent cover system is articulated with the sofa armrest and supports opening and closing from 0 to 180 degrees. It integrates a micro laser projection (FOV 120 degrees, resolution 4K) and a physiological monitoring module (EEG electrodes, blood oxygen sensor).

[0007] Dynamic somatosensory mapping in the functional module interaction logic can achieve acceleration simulation and tactile enhancement. Acceleration simulation: The motion platform and the pneumatic compression unit work together to achieve a sense of weightlessness (such as the base sinking and chest pressure reduction when falling from space); tactile enhancement: The conductive fabric changes resistance according to the scene density (such as reducing local pressure when touching a virtual water flow), and the stretch band simulates resistance (such as the armband exerts reverse tension when pulling a bow).

[0008] Environment-body synergy: explosion scene → base vibration (20Hz) + instant compression of the back (80kPa) + release of gunpowder smell; rainforest scene → slightly wet touch of the seat (atomizer spray) + vine-wrapped stretching feedback.

[0009] The core innovations of the Metaverse multimodal immersive sofa are reflected in three aspects: full-dimensional somatosensory fusion architecture, Metaverse scene adaptation engine, and safety redundancy design.

[0010] Full-dimensional body-sensing fusion architecture: Integrates vestibular sense (motion platform), skin touch (pressure / stretching), and environmental sense (smell / temperature and humidity) into a single sofa carrier.

[0011] The Metaverse scene adaptation engine can predict AI behavior: preload tactile feedback parameters based on user motion capture (such as the amplitude of hand raising); realize physiological-environmental closed loop: automatically reduce the intensity of the motion platform according to changes in heart rate (such as switching to static mode when signs of motion sickness are detected).

[0012] The system of the Metaverse multi-modal immersive sofa has been designed with safety redundancy and adopts dual-path emergency braking, including electrical control: MOSFET power-off protection (response time <10ms); and mechanical redundancy: pneumatic compression unit pressure relief valve (normally open design, automatically opened when power is off); The system is equipped with an EEG monitoring function, which will forcibly reduce the intensity of environmental stimulation when abnormal alpha waves (drowsiness) are detected.

[0013] The Metaverse multi-modal immersive sofa is ergonomically optimized. The curved surface of the sofa complies with the ISO 11226 sitting posture standard, and the pressure distribution uniformity is >90%. The transparent cover supports infinite adjustment (0-180°) to accommodate different user heights. The maintainability design is reflected in the quick-release interface (ISO 16028 standard) of the pneumatic unit, which supports replacement within 10 seconds. The stretch belt is modularly designed and can be disassembled without tools. Expansion interface: A USB4 interface is reserved to support external brain-computer interface (BCI) devices; the top rail is compatible with third-party VR headset brackets.

[0019] Example 1: Space battle scene (game "Star Citizen"), user action: maneuvering the spacecraft to make a sharp turn; system response: the motion platform tilts 12° to the right (simulating centrifugal force), and the right arm stretch belt simultaneously applies 50N resistance; the back pneumatic unit releases pressure to 20kPa (simulating the loose feeling of the seat belt in a weightless state); the transparent cover releases the smell of "metal ionization", and the laser projection generates starlight special effects outside the cabin; the bone conduction unit plays the low-frequency roar of the engine (20-100Hz).

[0020] Example 2: Virtual social scene (Metaverse meeting). Safety mechanism test: simulate a sudden arrhythmia of the user (>150bpm for 10 seconds): the motion platform slowly descends to a horizontal position; all compression units are depressurized to 0kPa; the transparent cover automatically opens and switches to ventilation mode; the speaker plays a voice prompt "Health protection mode has been activated".
