Abstract
A 3D input apparatus including a first object, a second object movable relative to the first object, and at least one sensor unit for detecting displacements and/or angular rotations of the objects relative to each other. Each sensor unit includes a magnetoresistive sensor, a magnetic field element, and a magnetic marker element. The magnetoresistive sensor and the magnetic field element of respectively one sensor unit are connected to one of the objects, and the marker element of said sensor unit is connected to the other object. For each sensor unit the magnetoresistive sensor of said sensor unit detects a magnetic field emitted by the magnetic field element of said sensor unit and influenced by the marker element of said sensor unit.
