Description

Technical Field

[0001] This invention relates to the field of head-mounted display devices and wireless communication technology, specifically to a lightweight, high-definition network signal direct-drive screen VR glasses adapted to 5G, 6G, WiFi6, WiFi7, WiFi8 and above networks. It is suitable for immersive scenarios such as virtual reality movie playback, cloud gaming, and remote virtual interaction. Through the architecture design of "direct network signal connection to display + no traditional computing module", it achieves an extremely lightweight and low-latency high-definition display experience. Background Technology

[0002] Virtual reality (VR) technology, as the core carrier of the next generation of human-computer interaction, has broad application prospects in consumer electronics, digital entertainment, remote collaboration, and other fields. However, existing VR devices, regardless of the connection method used, still have core pain points and struggle to adapt to the compatibility requirements of multiple network generations: The problem of heavy wear is prominent: Traditional VR headsets (all-in-one, PC-based, and ordinary wireless models) generally have built-in CPUs, motherboards and other computing modules, and their weight often exceeds 300 grams, with some high-performance models weighing more than 500 grams, which puts pressure on the face and bridge of the nose and is extremely uncomfortable to use.

[0003] Running large-scale cloud games results in significant latency and image quality loss: Wireless VR devices rely on local encoding or decoding or traditional 5G and WiFi 6 protocols for transmission, with end-to-end latency exceeding 15ms, which can easily cause dizziness, and the encoding compression also leads to image quality degradation; although wired VR has lower latency, the cable constraints affect flexibility, and the problem of heavy devices has not yet been solved.

[0004] Insufficient multi-generation network compatibility: Existing devices lack cross-generation network compatibility design. Models adapted to 5G and WiFi 6 cannot fully utilize the high speed (10Gbps+) and low latency characteristics of WiFi 7 and 6G, which contradicts the future industry trend of "cloud computing power + terminal display".

[0005] Therefore, there is an urgent need in this field for a disruptive VR glasses solution that abandons traditional computing and redundant modules, fully adapts to 5G, 6G, WiFi 6, WiFi 7, WiFi 8 and above networks, solves core problems such as weight, latency, and image quality loss, and takes into account current usage and future iteration needs, providing an extremely lightweight, low-latency, and high-definition virtual reality experience. Summary of the Invention

[0006] Core objective By abandoning redundant computing modules such as CPU, motherboard, and memory in traditional VR devices, and through "dedicated mobile APP control + direct network connection to glasses + direct signal drive + minimalist hardware architecture," it solves the pain points of heavy equipment, high latency, and poor compatibility, achieving multi-network compatibility, extreme lightweight design, and convenient and secure operation throughout the entire process (e.g., Figure 1 (001).

[0007] Core Architecture It includes a wireless receiving module, a signal conversion module, a Bluetooth communication module, a display module, an optical module, a power supply module, a lightweight wearing module, a posture interaction module, and a minimalist control module; the mobile APP is the core control and interaction hub, and the glasses are only responsible for "direct network connection - signal reception - conversion drive - high-definition display - posture capture", without any complicated operation functions.

[0008] Core module functions Wireless receiver module: Compatible with 5G, 6G, WiFi 6 to WiFi 8 and above network signals. The glasses independently scan and directly connect to the target network to receive high-definition video streams from cloud servers or game servers, performing only decoding without computation (e.g., Figure 1 (002) Signal conversion module: Directly converts the decoded signal into the screen drive signal without intermediate calculations, ensuring low latency (e.g., Figure 1 (003) Bluetooth communication module: Receives commands from mobile APP, connects to external devices (mouse or VR controller), and provides real-time feedback on the glasses' status (battery level, signal strength, or network connection status). Display module: ≥5K high-definition screen for both eyes, capable of projecting synchronized operation interfaces of mobile APP (such as resource selection, parameter adjustment, server switching, etc.) and minimalist status prompts (such as "connected to target server" "game is about to start"). The core display server content is displayed (all operation interfaces are synchronously projected by the mobile APP, and the glasses are only responsible for receiving drive signals and displaying them). Posture Interaction Module: Low-power nine-axis IMU captures head posture, adapts to viewpoint control, and the data is synchronized to the mobile APP via Bluetooth and then forwarded to the server; Minimalist Control Module: The low-power MCU only executes commands from the mobile app and provides feedback on device status. It has no general computing capabilities and its built-in 1KB storage unit only stores the device number and binding information (such as...). Figure 1 (004) Mobile App: Connection Management: Bluetooth pairing and binding to glasses; supports network list display and WiFi password input (synced to glasses for direct connection); automatically remembers frequently used networks, allowing for one-click connection upon next power-on (e.g., ...). Figure 1 (005) Resource management: Integrates cloud gaming, office, or film and television resource libraries, supports server filtering (such as region or network type), game or application search and collection, and displays details (image quality, supported functions, or duration and price). Payment and Permissions: Integrates secure payment channels such as WeChat or Alipay, allows order inquiry, generates unique access credentials and synchronizes them to the server; Device control: issues start, pause or end commands, displays glasses battery level and remaining usage time in real time, and supports remote unbinding, network switching and simplified firmware upgrades; Interactive assistance: Displays the connection status of external devices connected to the glasses (such as whether the gamepad, mouse, or steering wheel has been successfully connected).

[0009] Core Process Mobile App Bluetooth Pairing with Glasses → Enter WiFi Password in App (syncs to Glasses, Glasses connect directly to network independently) → Select Server in App → Select Game in App → Complete Payment → App issues Startup Command → Glasses connect directly to server to receive video stream → Direct display → Head posture + external controller interaction → End of use in App or on Glasses.

[0010] Core advantages Extremely lightweight (≤100 grams), extending continuous use time; Multi-network compatibility + end-to-end latency ≤10ms, suitable for various types of cloud games such as 3A games and high-definition office scenarios; Mobile APP enables closed-loop control of the entire process: from network connection, resource selection, payment to device management, all completed in one stop; High-definition direct drive plus complete interaction: 5K high-definition display plus head posture and external device control, balancing immersion and practicality; High reliability and simplification: The streamlined architecture reduces redundant components, the low-power modules have no heat dissipation burden, the failure rate is low, and the cost is controllable.

It is equipped with a top-load-bearing headband, with the top made of elastic nylon and the sides made of medical-grade soft silicone. The face pads use medical-grade liquid silicone for light blocking, 5-8mm thick, with ventilation holes, balancing comfort and light blocking (e.g., ...). Figure 1 (001).

[0019] 8. Gesture Interaction and Minimalist Control Module The attitude interaction section uses a low-power nine-axis IMU (such as the Bosch BMI160), integrating an accelerometer, gyroscope, and magnetometer. It only captures head rotation and tilt postures, without spatial positioning capabilities. The sampling rate is ≥100Hz, the recognition latency is ≤10ms, and the weight is ≤5 grams. Attitude data is synchronized to a mobile app via Bluetooth and then forwarded to the server, enabling viewpoint tracking and compatibility with subsequent higher-precision sensors.

Users can filter resources, complete payments, and issue activation commands through the app. The glasses receive video and audio signals from the server, convert them, drive the display, and output audio via Bluetooth or a headphone jack. Users can operate the glasses by using head posture and external interactive devices. Brightness and volume can be quickly adjusted via physical buttons or precisely adjusted via the app. After use, the glasses stop receiving audio and video signals and display a notification upon receiving a command from the app or when the time limit is reached.
