Description

Technical Field

[0001] The present invention belongs to the technical field of metaverse interaction, and specifically relates to an external digital human environment simulation plugin based on a limited action space. Through dynamic space delineation and migration technology, extreme environments and combat damages are generated within an independent action space of 2m×2m×2.4m, supporting space movement, switch control, and environment overlay, to achieve a high-precision and low-resource-occupancy digital human interaction experience. Background Art

[0002] The prior art has the following problems: First, global resource consumption: Traditional environment simulation systems (such as patent CN119292466A "Multimodal-based Digital Human Interaction Method and System") require full-scene rendering, with a high computational resource occupancy rate; Second, poor spatial flexibility: Fixed scopes cannot adapt to the plot movement requirements (compared with patent CN118445458A "Digital Human Interaction Method, Device, Equipment, Medium, and Product in a Virtual Space" which only supports static areas); Third, the risk of environmental residue: Parameter interference may be left after the system is shut down. The present invention proposes a dynamic space anchoring technology and an environment overlay algorithm, combined with a lightweight design of the external plugin, to achieve precise space control and instantaneous environment switching. Summary of the Invention

[0003] The system architecture of the present invention is as Figure 1 , and the core modules of this system are connected to the metaverse / game engine main software through environmental parameters and scene data.

[0004] The core modules of the present invention include a space anchor device, an action space generator, an environment overlay module, and a state manager.

[0005] Space anchor device: Millimeter-wave radar (accuracy ±1cm) + infrared sensor deployed at the six vertices of the action space (see Figure 3 ).

[0006] Action space generator: Real-time calculation of the 2m×2m×2.4m boundary, which only takes effect on the internal digital humans.

[0007] Environment overlay module: Through Shader replacement technology, extreme environment special effects (such as lava / ice and snow) are overlaid on the original scene (see Figure 4 ).

[0008] State manager: Supports three modes - on (full effect), sleep (maintaining 20% effect), off (fully uninstalled).

[0009] The present invention adopts two core innovative technologies. The first is dynamic space migration (see Figure 2). The second is the instantaneous environmental switch, and its indicators are as follows: from on → off ≤ 0.2 seconds, the resource release rate reaches 100%, and the residual error is 0 °C / 0 dB; from sleep → off ≤ 0.1 second, the resource release rate is 80%, and the residual error is ±0.5 °C (see Figure 5 ).

[0010] The present invention can be combined with commercial operations. For example, space skin NFTs are issued: users purchase different themed space appearances (such as "Interstellar Cage" and "Ancient Tomb Secret Room"); developers receive a share of the profit: charged according to the space usage duration (for example, 0.1 yuan per minute, and developers receive 70%).

[0016] Example 1: Virtual agent training. Scenario: An agent enters a 2m × 2m × 2.4m "electromagnetic cage" space and endures high - voltage electric shocks; System response: The space moves to different areas with the plot (error < 5 cm); After closing the space, the burn marks on the digital human's clothing automatically disappear, and the environmental temperature instantaneously recovers; Training data generates a short video: "How Agents Escape a High - Voltage Cage in 3 Seconds".

[0017] Example 2: Metaverse escape room. User operation: Purchase the space skin (NFT) of the "gas chamber", and invite friends to challenge; Damage logic: The gas concentration in the space increases by 10% per second, and the equipped resistance value determines the survival time; After closing the space, the gas special effects completely disappear, and friends can safely watch.

[0018] Example 3: Movie special effect preview. Director's requirement: In a 10m × 10m shooting studio, locally superimpose a 2m × 2m × 2.4m "tornado" space; Technical implementation: Actors only feel the wind force (dynamically enhanced from level 7 to level 10) within the acting space; After closing the plug - in, the on - site temperature and humidity recover to the initial value within 5 seconds (error ±0.3 °C).
