CA 2146318

The present invention provides a position-sensing system which employs sensors incorporating magnetoresistive material. The position of a magnetic information input member is determined through the resistance change ofthe magnetoresistive sensor in response to the magnetic field from the magnetic information input member. Exemplary magnetoresistive materials are lanthanum manganites having high magnetoresistive ratios. Two-dimensional position sensingsystems for graphics tablets are also described.
