Abstract
It was demonstrated that a specific arrangement of magnet and single 3D magnetic field sensor can effectively resolve the motion of a three-axis joystick. However, the proposed configuration lacks robustness against stray magnetic fields. Building on the original concept, this work explores the feasibility of achieving stray field immunity through differential measurement techniques. Our findings show that while a stray field robust design is attainable, it imposes stringent requirements on system design and sensor arrangement to ensure reliable operation under varying magnetic conditions.
