Magnetic Trigger Tracking for Low-Latency Visual Effects
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for detecting trigger events in visual effects suffer from unacceptable latency, delay, inaccuracy, and unreliability, making them unsuitable for achieving the desired level of realism in immersive experiences.
Innovation Solution
A system comprising active and passive magnetic emitters, a magnetic field detector, and a processor that evaluates changes in the magnetic field to initiate visual effects, allowing for predictive analysis and timely activation of effects without user-detectible lag, and integrating passive magnetic components with tracked objects to compute three-dimensional volume maps and model spatial motion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional trigger detection systems are used, then visual effects can be triggered, but unacceptable latency and delay occur reducing realism
Solution Approach 1:
The system performs preliminary tracking and prediction of tracked object states before the actual trigger event occurs. By continuously monitoring magnetic field changes and predicting future positions, the system prepares trigger signals in advance, eliminating perceptible latency while maintaining accurate timing relative to the actual trigger moment.
2Measurement precision
If conventional tracking systems are used, then trigger events can be detected, but inaccuracy occurs in certain settings
Solution Approach 1:
The system introduces passive magnetic emitters as intermediary elements attached to tracked objects, which interact with active magnetic emitters to create measurable magnetic field patterns. This intermediary magnetic field mechanism provides reliable and accurate tracking data across various environmental settings, overcoming the limitations of conventional direct detection methods.
3Loss of information
If passive magnetic emitters are integrated with tracked objects, then three-dimensional volume maps can be computed, but device complexity increases
Solution Approach 1:
The system segments the tracking functionality into separate components: active magnetic emitters that generate fields, passive magnetic emitters attached to tracked objects, and a processing system that computes volume maps. This segmentation allows each component to be optimized independently while collectively achieving complete three-dimensional spatial tracking without requiring complex integration.
