Description

Technical Field

[0001] The present invention belongs to the technical field of metaverse interaction devices, and particularly relates to a hemispherical microenvironment system for expandable display interaction. Through an integrated arc-shaped display screen and a dual-mode design compatible with VR glasses, combined with multi-modal environmental feedback and physiological safety monitoring, a high-immersion and high-security virtual-real fusion experience is achieved. Background Art

[0002] The prior art has the following three defects. Firstly, the display interaction is single: the game peripherals provided for home and individual users usually only support fixed screen display or projection, and cannot adapt to user preferences (such as naked-eye interaction or VR immersion); secondly, the spatial compatibility is poor: traditional VR headsets are separated from environmental devices, resulting in spatial positioning errors and sensory disconnection; thirdly, the safety risks are superimposed: the enclosed display device lacks the ability to perceive user actions and is prone to collision risks. The present invention proposes a dual-mode display solution to achieve deep coupling of display interaction and safety control through hardware modular design. Summary of the Invention

[0003] The core technical solution of the present invention includes two parts: a hardware architecture (dual display mode) and core functional modules.

[0004] The hardware architecture is a dual display mode, and can adopt Mode A (integrated arc-shaped screen) or Mode B (external VR glasses). Mode A (integrated arc-shaped screen) uses an arc-shaped display screen, whose technical parameters are flexible OLED material (curvature radius 800mm, thickness ≤ 2mm), covering the upper half of the inner side of the hemispherical cover (viewing angle 120°), integrating a micro TOF sensor array (resolution 640×480, frame rate 60Hz), and supporting gesture recognition (accuracy ±5mm); the present invention has optimized the design in terms of interaction, tactile feedback: piezoelectric vibration units (frequency 50 - 200Hz) are arranged at the edge of the screen to simulate the touch of virtual objects; eye movement tracking: an infrared camera (wavelength 850nm) captures the fixation point in real time to dynamically adjust the environmental feedback intensity.

[0005] The hardware architecture has carried out device compatibility design: a Type-C / MagSafe interface is reserved at the top of the hemispherical cover to directly connect to mainstream VR devices such as MetaQuest Pro; wireless synchronization protocol: environmental data (odor / wind field parameters) is transmitted through Wi-Fi 6E, and the time delay < 15ms.

[0006] The hardware architecture has enhanced spatial positioning: AprilTag two-dimensional codes are arranged on the inner wall of the hemispherical cover (density 4 pieces / m²) to assist VR Inside-Out positioning; the environmental feedback is bound to the virtual scene coordinates (such as the wind direction matching the VR visual displacement vector).

[0007] The core functional module is equipped with a multimodal collaborative engine, which has a display-environment mapping algorithm: in curved screen mode, HSV color space analysis drives the light effect (such as the blue area of ​​the screen corresponds to local cooling); in VR mode, SteamVR data stream analysis triggers a directional wind field (such as strong wind at the top when diving in a flying game). The core functional module designs gesture interaction logic: defines 6 basic gestures (grab / slide / click, etc.), and classifies them in real time through a CNN model (MobileNetV3); and sets a safety protection zone: when the hand approaches 10cm from the edge of the screen, the wind field intensity is automatically reduced (to prevent accidental touch).

[0008] The core innovations of the present invention are embodied in three aspects: scalable display mode architecture, interactive-safety linkage mechanism, and cost-optimized design.

[0009] Scalable display mode architecture: the first hardware-level compatible design between curved screen and VR glasses (compared to Sony PSVR2 which only supports a single mode); adopts MagSafe+Type-C dual interface solution.

[0010] Interaction-safety linkage mechanism: Gesture misoperation protection: When non-preset gestures are recognized for three consecutive times, it will automatically switch to voice control mode; VR anti-motion sickness strategy: Dynamically adjust the environmental feedback intensity according to the acceleration of the user's headset (such as reducing the wind field intensity by 50% during high-speed rotation).

[0011] Ergonomic optimization: The curvature of the curved screen meets the ISO 13406-2 visual fatigue standard, and the eye fatigue index decreases by 37% after 2 hours of continuous use; the VR interface position is adapted to 95% of adult sitting postures (the area that can be reached when the elbows naturally droop).

[0012] Cost-optimized design: The curved screen version adopts the public OLED drive solution (Solomon Technology SSD2828 chip) to reduce BOM costs; the VR mode reuses existing hardware resources (such as reusing wind farm modules to achieve spatial positioning enhancement).

[0017] Example 1: Curved screen mode (home game scenario). User operation: Grab virtual objects in a VR game; System response: The TOF sensor recognizes the grabbing gesture → The piezoelectric unit generates a short pulse vibration (100 Hz, 200 ms); The blue light effect on the screen diffuses → The semiconductor refrigeration chip cools down by 3°C; When the hand approaches the screen edge, the side fan automatically stops rotating.

[0018] Example 2: VR mode (commercial experience hall). Safety test: When the user quickly turns their head, it causes a tendency of motion sickness → The system reduces the wind field intensity and injects a mint smell to refresh; When the VR positioning is lost, the AprilTag is used to assist in recalibration (error < 2 cm).
