1. A method for operating a mobile device having an imaging device, comprising:

  • determining position of the mobile device using unique position-representative marks, each of the marks having encoded information including a current position of the mark and being different than any other marks, by;

    obtaining an image including one of the marks using the imaging device;

    decoding the mark, using a processor, to obtain the position of the mark in the obtained image; and

    analyzing differences between appearance of the mark in the obtained image and appearance of the mark from a known position and, using the processor, determining the position of the mobile device based on;

    1) the analyzed differences between the appearance of the mark in the obtained image and the appearance of the mark from the known position and2) the obtained position of the mark in the obtained image such that the determined position varies dependent on the analyzed differences between the appearance of the mark in the obtained image and the appearance of the mark from the known position; and

    altering operation of at least one component of the mobile device based on the determined position of the mobile device.
