Solution Overview
Problem
Existing virtual reality systems lack realistic and engaging interactions with virtual objects, particularly failing to accurately simulate sports-specific physical motions and collisions, which limits the effectiveness of multiuser physical competition and assessment systems.

A system that tracks users in different physical spaces and resolves virtual collisions based on their postures and power, using wireless position tracking and computer systems to update user locations and determine collision outcomes, allowing for realistic modeling of real-world collisions and interactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If virtual reality systems use simple collision detection, then system complexity is reduced, but the realism and accuracy of collision interactions deteriorates
Solution Approach 1:
The system changes parameters by incorporating posture detection and power calculation metrics into collision resolution. Instead of simple position-based detection, the system evaluates user posture (standing, crouching, jumping) and calculates power based on movement velocity and force, creating more realistic collision outcomes without requiring overly complex hardware modifications.
Solution Approach 2:
The collision detection system transitions from static position checking to dynamic evaluation that considers user movement state, posture changes, and power metrics. The system continuously monitors and adjusts collision outcomes based on real-time physical attributes, making interactions more realistic while maintaining manageable system complexity through incremental computational approaches.
2Measurement precision
If the system tracks detailed user postures and movements, then collision resolution accuracy improves, but measurement and detection difficulty increases
Solution Approach 1:
The system uses multi-functional tracking devices that simultaneously capture position, posture, and movement data. The same sensors and cameras used for basic position tracking are leveraged to detect posture angles, movement velocity, and acceleration, eliminating the need for separate specialized measurement systems while achieving comprehensive collision analysis.
Solution Approach 2:
The system introduces intermediary computational models that translate raw sensor data into meaningful posture and power metrics. Software algorithms serve as intermediaries, processing accelerometer data, camera feed, and position information to derive collision-relevant parameters, thereby simplifying the detection process while maintaining high measurement precision.
3Adaptability or versatility
If the system allows users of different sizes and abilities to compete, then adaptability and fairness improve, but determining collision outcomes becomes more complex
Solution Approach 1:
The system applies localized adjustment factors to collision resolution based on individual user characteristics. Instead of using a single universal collision model, the system modifies collision outcomes according to each user's measured attributes (size, strength, posture), allowing fair competition among diverse users while keeping the base collision resolution logic relatively simple and modular.

AI summary
An interactive system tracks users in different physical spaces, both corresponding to a virtual space. The system resolves virtual collisions between the users in the virtual space. The system may resolve the virtual collision by examining the postures and power of the users. Different resolution criteria (“rules”) may be used for same-posture and different postures collisions.
