The idea
Combine magnetometer samples with camera positions to map a magnetic field around a speaker, motor, or power supply as a 3D sculpture.
How it works
- Record magnetic-field vectors while moving one phone around a subject.
- Use camera and motion tracking to place each sample and rotate its vector into the shared coordinate frame.
- Render field strength and direction as a 3D sculpture and compare repeat scans or a baseline.
AI’s role: Compare a measured field map with a baseline and describe patterns; calibration and coordinate transforms keep the vector measurements tied to the scan.
First demonstration
Scan around one speaker or motor from several paths, repeat the scan, and compare the measured field map with a stationary baseline.
What to solve next
How much do phone calibration, nearby metal, and scan drift change the map, and which patterns repeat across devices?
