Virtual Space Control System Reducing Computational Load via Image Copying
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for reproducing a situation in one virtual space within another virtual space in a computer system result in high process loads, making it difficult to provide enriched virtual experiences, as they require replicating and controlling all objects from the source virtual space, which is computationally intensive.
Innovation Solution
A computer system that sets a virtual space in a first virtual space and performs space expression control to embody a second virtual space, using captured images and virtual objects, reducing the computational load by only rendering necessary elements within the field of view of the user, and controlling the position and orientation of these objects based on the user's point of view.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If processing executed in another virtual space is reproduced by executing the same processing in the destination virtual space, then the virtual experience is enriched, but the process load becomes extremely high
Solution Approach 1:
The patent uses image capture and display techniques to create a visual copy of the source virtual space within the destination virtual space. Instead of executing processing in both spaces, the system captures images from the source virtual space and displays them in the destination space, providing enriched virtual experience with minimal process load.
Solution Approach 2:
The patent extracts only the visual representation (images) from the source virtual space rather than reproducing the entire processing environment. By taking out only the necessary visual elements and displaying them in the destination space, the system avoids the extreme process load of full processing reproduction.
2Manufacturing precision
If all objects from the source virtual space are replicated and controlled in the destination virtual space, then the situation is accurately reproduced, but the computational intensity increases significantly
Solution Approach 1:
The patent creates a visual copy by capturing images from the source virtual space and displaying them in the destination space. This approach maintains reproduction accuracy for the visual aspect while avoiding the computational energy required to replicate and control all objects in three-dimensional space.
Solution Approach 2:
The patent uses two-dimensional image representations instead of full three-dimensional object replicates. These image copies are computationally inexpensive to create and maintain, providing sufficient visual reproduction without the high computational energy cost of full object replication.
3Productivity
If a virtual space is set to express an embodiment space and only necessary elements are rendered within the user's field of view, then the computational load is reduced, but the complexity of controlling position and orientation increases
Solution Approach 1:
The patent applies local quality by rendering only the necessary portions of the virtual space that fall within the user's field of view. Instead of rendering the entire virtual space uniformly, the system selectively renders only the local area that the user can currently see, reducing computational load while maintaining visual quality where needed.
Solution Approach 2:
The patent implements dynamic control where the rendered area adjusts based on the user's viewpoint and field of view. As the user moves or changes orientation, the system dynamically updates which portions of the virtual space are rendered, optimizing computational resources based on current viewing conditions.

AI summary
A virtual space control system sets a virtual space in a first virtual space, and expresses an embodiment space embodying a second virtual space in the virtual space. Virtual objects embodying embodiment target objects in the second virtual space are disposed in the virtual space. A disposition configuration of the virtual objects in the first virtual space is aligned with a disposition configuration of the embodiment target objects in the second virtual space, which are associated with the virtual objects. captured images serving as sources of embodiment images that undergo texture mapping onto the virtual objects are generated in a sub-server system. The embodiment images are created by causing the captured images to undergo calculation amount reduction processing.
