Mapping 2D Arena Movements to 3D Virtual Worlds
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current arena-based virtual reality systems provide only a two-dimensional experience, limiting users to flat open spaces and restricting movement to two-dimensional directions within the virtual world, whereas users desire a richer experience with three-dimensional interactions.
Innovation Solution
A system comprising a virtual reality server connected to multiple cameras and displays, which constructs a 3D virtual world model by mapping 2D arena movements into 3D movements, allowing users to transition between elevations and interact with the virtual environment in a more immersive manner, using tracking markers and sensory enhancement devices to update the virtual reality model and provide sensory stimuli.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the VR system maps arena movements into 2-D movements within the virtual world, then the system complexity remains manageable, but the user experience is limited to two-dimensional interaction
Solution Approach 1:
The patent applies dimensionality change by mapping 2-D arena movements into 3-D virtual world movements. The system constructs a 3-D virtual world model and enables users to transition between elevations, transforming the traditional 2-D movement constraint into 3-D spatial interaction. This allows users to experience vertical displacement and elevation changes in the virtual environment while maintaining the physical 2-D arena setup.
2Adaptability or versatility
If the VR system allows three-dimensional movement within the virtual world, then the user experience becomes richer and more immersive, but the system complexity increases
Solution Approach 1:
The system resolves this contradiction by implementing 3-D virtual world construction with elevation transitions. The virtual environment includes multiple elevation levels (ground level, elevated platforms, staircases) that map to 2-D arena positions. When users move in the arena, the system calculates corresponding 3-D positions in the virtual world, enabling rich spatial interaction without requiring physical 3-D arena infrastructure.
Solution Approach 2:
The patent uses an intermediary computational model that translates between 2-D arena coordinates and 3-D virtual world coordinates. The system constructs a mapping relationship where 2-D arena positions correspond to multiple possible 3-D positions based on the virtual environment geometry. This intermediary layer handles the complexity of 3-D mapping while keeping the physical arena setup relatively simple.
3Measurement precision
If the system uses multiple cameras to track arena movements, then the measurement precision of user position improves, but the device complexity and processing requirements increase
Solution Approach 1:
The patent merges data from multiple cameras to achieve precise 3-D position tracking in the arena. The system combines images from multiple camera viewpoints to calculate accurate user positions and orientations. This multi-camera approach provides redundant measurement data that improves tracking precision and reliability while handling the computational complexity through efficient image processing algorithms.

AI summary
A virtual reality system maps primarily 2-D arena movements into 3-D virtual worlds. Movement into specific physical arena areas or directions triggers virtual world effects such as changing elevation, moving on a different elevation, walking on walls or walking on the outer surface of an object. The 3D-VR system supports multiple simultaneous people at different virtual elevations and provides a realistic, interesting and exciting simulation experience.
