1. A method of determining the time-varying absolute position of device in respect to a surface, the method comprising the steps of:

  • measuring at least one absolute position of the device in respect to the surface;

    measuring a time-varying vector representing the movement of the device in respect to the surface; and

    initialising the position of vector to the at least one absolute position measurement thereby measuring the absolute position of the vector and thus the time-varying absolute position of the device.
