1. A multiple axis data input apparatus, comprising:

  • a source of magnetic flux;

    a swash plate coupled to the magnetic flux and positionable by an actuator handle in an orientation having a predetermined number of axes, the predetermined number being at least four;

    multiple sensors positioned in proximity to the swash plate and positioned such that each sensor receives an amount of the magnetic flux that depends on an orientation-induced spacing between the swash plate and the sensor and in which each sensor generates a signal in response to the amount of magnetic flux received; and

    a controller that receives and processes the signals and generates spatial orientation data corresponding to the orientation of the swash plate in each of the predetermined number of axes.
