1. A user-controlled pointing device for controlling a movement of an object observed by a user in a visual scene, the user-controlled pointing device comprising:

  • one or more magnetic sensors each operable to measure a magnetic field component associated with a respective orthogonal direction; and

    a processing circuit operable to receive an output signal from each magnetic sensor that represents a respective measured magnetic field component and determine positional information for the object based on a movement of the user-controlled pointing device.
