Solution Overview
Problem
Current virtual reality devices lack the ability to accurately track and reflect the movement of a user's hands in real-time, limiting the immersive experience by not providing a precise and interactive interface with virtual objects.
Innovation Solution
An electronic device comprising a source that generates a magnetic field, a motion detector that obtains the user's hand coordinates based on the magnetic field, and a virtual reality providing device that reflects these coordinates, allowing for accurate tracking and interaction within a virtual environment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a magnetic field-based tracking system is implemented, then hand movement tracking precision is improved, but device complexity increases due to additional sensors and processing requirements
Solution Approach 1:
A magnetic field is introduced as an intermediary medium between the user's hand and the tracking system. The magnetic field acts as a carrier that transmits hand movement information to sensors, enabling precise tracking without direct mechanical contact or complex optical systems. The magnetic field generator and sensors work together as an intermediary system that simplifies the overall tracking architecture while maintaining high precision.
2Ease of operation
If real-time hand coordinate tracking is implemented, then virtual reality interactivity is improved, but processing time and computational load increase
Solution Approach 1:
The system performs preliminary actions by continuously maintaining a magnetic field in the tracking space and having sensors ready to detect hand coordinates. This pre-established magnetic field environment allows for immediate detection and processing of hand movements without requiring system re-initialization or complex calculations when the user interacts with virtual objects, thereby reducing processing time while maintaining real-time interactivity.
