1. A perspective tracking system comprising:

  • a computer-based perspective tracking device; and

    an array of emitters configured to define at least one area of interest based on emitted signals from at least two emitters in the array of emitters;

    wherein the computer-based perspective tracking device is configured to determine a spatial position, orientation, and size of the area of interest based on the emitted signals from the array of emitters; and

    wherein the computer-based perspective tracking system is configured to measure a light intensity of each of the at least two emitters in the array of emitters over a detection threshold and generate a correction equation to the light intensity measurement that yields temperature-based offsets.
