Implementation and Benchmark of Magnetic Tracking on Mobile Platforms

Abstract

Magnetic tracking algorithms have demonstrated impressive accuracy in research settings, but their deployment on commodity mobile hardware — with limited CPU/GPU and strict power budgets — remains largely unexplored. MagAndroid is the first systematic implementation and benchmark of magnetic tracking on commodity Android smartphones.

By carefully mapping the tracking pipeline to mobile compute primitives and leveraging the built-in magnetometer array, MagAndroid achieves real-time tracking with high accuracy and low energy consumption on unmodified Android devices — bringing magnetic sensing out of the lab and into everyday mobile applications.

Key Contributions

• First deployment of magnetic tracking on commodity Android smartphones.
• Comprehensive benchmark of accuracy vs. energy trade-offs on mobile hardware.
• Open-source implementation: github.com/zychen-cs/MagAndroid.
