Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of metaverse digital human interaction, and specifically relates to a digital human exclusive scene space system. Through dynamic space expansion technology, environmental database binding mechanism and equipment box integrated design, a portable and configurable multi-modal environmental space is provided for each digital human, supporting scene migration, equipment invocation and permission management in the metaverse. Background Art
[0002] The existing technologies have the following problems: Firstly, poor environmental versatility: Traditional metaverse scenes (such as patent CN119292466A "Multimodal Digital Human Interaction Method and System") cannot be bound to digital human individuals, and the scene needs to be reloaded when switching; Secondly, low action compatibility: The fixed space size limits the amplitude of digital human actions (such as jumping and combat skills cannot be unfolded); Thirdly, data isolation: The environmental state and historical records are stored separately (compared with patent CN117671095A "A Multimodal Digital Human State Prediction System and Its Method", the database and equipment system are not integrated).
[0003] The present invention proposes scene space binding technology and dynamic space expansion protocol to achieve deep coupling between digital humans and scenes. Summary of the Invention
[0004] The system architecture of the present invention is shown in Figure 1 , the digital human identity ID is bound to the scene space, and the environmental space includes an environmental database and an equipment box.
[0005] The scene space binding module adopts space anchoring technology: Each scene space uses millimeter-wave radars (TI AWR1843) and infrared sensors (accuracy ±1 cm) deployed at the six vertices to track the position and actions of digital humans in real time; The space coordinates are strongly bound to the digital human identity ID, supporting the simultaneous binding of multiple sets of scene spaces (such as home / battle / exploration modes), and switching through voice or gesture commands; Data storage: The scene space configuration parameters (temperature, humidity, gravity, etc.) and the digital human behavior history records are stored in the form of blockchain shards to ensure immutability (see Figure 4 ).
[0006] The dynamic space expansion protocol adopts an intelligent expansion algorithm:
python def space_expansion(action_type, duration): if action_type == "Giantization" and duration >= 5s: return (5m, 5m, 5m) elif action_type == "High-altitude jump" and height > 1.5m: return (3m, 3m, 5m) elif action_type == "Combat skill" and skill_radius > 2m: return (skill_radius + 1m, skill_radius + 1m, default_height)
[0007] Boundary softening process: When the space expands, a gradient Shader transition is used to avoid visual splitting (the transparency decreases from 100% to 30%, taking 0.5 seconds).
[0008] The comparison of dynamic space expansion changes is shown in Table 1: Table 1: Dynamic space expansion Action type Trigger condition Expansion size Response time Gigantification Height > 2m for 5 seconds 5m × 5m × 5m ≤ 0.3 seconds High-altitude jump Airborne height > 1.5m 3m × 3m × 5m ≤ 0.2 seconds Release of combat skills Skill range > 2m According to the skill radius + 1m Expansion ≤ 0.1 seconds 。
[0009] In the equipment interaction logic of the equipment box integration component, a resistance calculation model is adopted: actual damage = (environmental basic damage × time decay coefficient) × (1 - equipment resistance%); time decay coefficient = 1 - (current time / equipment durability time); the permission levels are set as follows: the owner can add, delete, and transfer the right of use / NFT casting, the renter can use it temporarily (up to 24 hours), and the visitor can only view the equipment attributes (see Figure 2 ).
[0010] Data call of the environmental database: Support retrieving the environmental status by timestamp and generating a 3D visualization report (compatible with Unity plugins).
[0011] The present invention can be commercially operated from two aspects. One is the scene space NFT: users can trade rare space templates (such as "Interstellar Prison", "Jurassic Swamp"); the other is the equipment rental market: charging by usage duration (for example, the radiation protection suit is 1 yuan per hour, and the developer's share is 70%) (see Figure 3 ).
[0012] The comparison between this solution and the traditional solution is shown in Table 2: Table 2: Comparison of technical advantages Comparison item Traditional metaverse scene system This invention Spatial flexibility Fixed size Dynamic expansion (from 2m × 2m × 2.4m to 5m × 5m × 5m) Data integrity Separation of environment and equipment data Binding to a unified database Commercial value Single-scene sales NFT space + equipment leasing + profit-sharing ecosystem Brief description of the drawings

[0017] Figure 5 : Flowchart of virtual medical first aid training Specific implementation manners
[0018] Example 1: Virtual giant battle training. Scene: The digital human activates the giantization skill (height 4.2m). System response: The space automatically expands to 5m³, and an earthquake-resistant structure is generated on the ground; the "giant knee pads" in the equipment box are unlocked (reducing the jumping impact damage by 50%); 5 seconds after the battle ends, the space returns to the standard size, and the knee pads are automatically recycled.
[0019] Example 2: Mars scientific research mission. Operation process: The first step is to bind the "Mars Storm" scene space (temperature -80°C / air pressure 0.01 kPa); the second step is to call the "pressurized spacesuit" (resistance value 90%) from the equipment box; the third step is when encountering a sandstorm, the space expands to 4m³ to accommodate scientific research equipment; the fourth step is to store the mission data in the database and generate a 3D mission report.
[0020] Example 3: Metaverse fashion show. Commercial application: The designer sells the NFT of the "T-stage wind tunnel" scene space (selling price 2,400 yuan); the model digital human wears the "wind-resistant dress" in the space (reducing the airflow influence by 70%); the audience pays to enter the space to experience (10 yuan per minute), and the income is divided between the designer and the platform at a ratio of 6:4.
[0021] Example 4: Virtual medical first aid training (see Figure 5 ). Scene requirements: Medical schools use the scene space to simulate rescue in earthquake-stricken areas. System response is as follows. Space configuration: Bind the "earthquake ruins" scene (size 3m × 3m × 3m, special effects of falling gravel + aftershock vibration feedback); the equipment box provides a "collapse-proof helmet" (60% anti-smashing) and a "life detector" (expanding the space to 4m³ to accommodate virtual wounded). Training process: The trainee digital human searches for the wounded in the aftershock (vibration frequency 5Hz per second), and the space expands dynamically with the movement; if the helmet is not worn, the gravel damage value increases by 20% per second; after a successful rescue, the scene automatically records the operation path and time, and generates a heat map of first aid efficiency. Data application: The training records are chained and stored for hospital assessment; outstanding trainees can mint the "earthquake-resistant expert" NFT badge as a professional qualification certification.
