Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a specific player moves around in the scene to create a spatial map using SLAM, then the spatial map is created, but the process consumes a lot of physical energy and is time-consuming
Solution Approach 1:
The patent creates a digital environment model that is a virtual copy of the real-world scene. Instead of requiring a player to physically move through the entire scene to create a map, the system uses the digital twin to simulate the tracking device's movement and generate viewpoint images computationally, dramatically reducing the time and physical effort required for map creation.
Solution Approach 2:
The patent replaces the mechanical physical movement of a player through the scene with computational simulation. The host computer simulates the tracking device's movement by processing the digital environment model and generating synthetic viewpoint images, substituting physical exploration with digital computation to achieve faster map creation.

3Ease of operation
If different players move around in the scene in different ways, then the spatial map quality becomes unstable
Solution Approach 1:
The patent creates a digital environment model that is a virtual copy of the real-world scene. Instead of requiring a player to physically move through the entire scene to create a map, the system uses the digital twin to simulate the tracking device's movement and generate viewpoint images computationally, dramatically reducing the time and physical effort required for map creation.
Solution Approach 2:
The patent changes the parameters of the map creation process from physical player movement to computational parameters. By controlling the virtual tracking device's movement through programmed paths and parameters in the digital environment model, the system ensures consistent and stable map quality regardless of how different players might physically move through the scene.
