ARCore: Visualizing the Invisible
summary
NSF-funded project builds a smartphone app, Physics Toolbox AR, that fuses ARCore + magnetometer readings to render floating magnetic field vectors in real 3D space; developers report a surprising user base from earlier sensor apps (about 2 million users). Implementation uses Sceneform/Filament and Google Play Services for AR, solves orientation by switching to quaternions, and exposes practical limits: device whitelisting, camera–sensor offsets, and cumulative drift. The visualization works reliably when devices are supported and users move slowly.
