Abstract
The present invention provides a position-sensing system which employs sensors incorporating magnetoresistive materials. The position of a magnetic information input member is determined through the resistance change of the 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 sensing systems for graphics tablets are also described.
