Abstract
A control method and a controller related to electromagnetic tracking are provided. In the method, a working position is determined, and the working position is the position at which a magnetic field sensor is located relative to a magnetic field emitter; an electrical characteristic of the magnetic field emitter or the magnetic field sensor is adjusted to a target characteristic corresponding to the working position. In this way, the positioning accuracy may be improved.
