Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Virtual reality systems fail to provide realistic interactions by maintaining unchanged physics rules and parameters when users or objects are scaled, leading to unrealistic feedback and experiences.

Engineering Contradiction Analysis
1Ease of operation
If physics rules and parameters are kept unchanged in virtual reality environments, then system complexity is reduced and ease of operation is improved, but realism and accuracy of interactions deteriorate when users or objects are scaled
Solution Approach 1:
The physics parameters are made dynamic and adaptable based on the relative scale between user and objects. The system automatically adjusts mass, friction, gravity, and other physics parameters according to the scaling relationship, allowing the physics model to adapt to different interaction scenarios while maintaining computational efficiency through rule-based adjustments.
Solution Approach 2:
The patent applies parameter changes by modifying physics parameters (mass, friction, gravity, etc.) based on the relative scale between user and objects. When scaling occurs, the system calculates appropriate parameter adjustments to maintain realistic interaction dynamics, such as adjusting mass proportionally to scale factors and modifying friction coefficients to account for changed contact surfaces.
2Reliability
If physics parameters are adjusted to match user scale, then realism of interactions is improved, but device complexity and computational requirements increase
Solution Approach 1:
The physics adjustment system is segmented into modular components: scale detection module, parameter calculation module, and physics rule application module. Each module handles specific aspects of the scaling process, allowing independent optimization and reducing overall system complexity. The segmentation enables reuse of calculation routines across different objects and scenarios.
Solution Approach 2:
The physics parameter adjustment system serves multiple functions: it handles scaling for different user sizes, adapts to various object types, and maintains consistency across different interaction modes. The universal parameter adjustment framework can be applied to any object-user interaction scenario, reducing the need for scenario-specific implementations and lowering overall device complexity.
