Abstract

A coordinate sensing system includes a magnetic member, a direction sensor, a first magnetic sensor and a processor, wherein the processor communicates with the direction sensor and is electrically connected to the first magnetic sensor. The magnetic member has a magnetic dipole moment. The direction sensor is used for sensing a direction of the magnetic dipole moment. The first magnetic sensor is used for sensing a first magnetic field of the magnetic member. The processor is used for calculating a first distance between the magnetic member and the first magnetic sensor and calculating a direction of the first distance according to a value of the magnetic dipole moment, the direction of the magnetic dipole moment and the first magnetic field. The processor is further used for calculating a coordinate of the magnetic member according to the first distance and the direction of the first distance.
