1. A system for remotely determining the location of a target in a three-dimensional real space, comprising:

  • two or more video cameras that image a target in a three-dimensional real space;

    a stereoscopic display that displays a three-dimensional image space combined from two video cameras of the two or more video cameras to a user;

    a binocular eyetracker that images a right eye and a left eye of the user as the user is observing the target in the stereoscopic video display, calculates a right gaze line of the right eye and a left gaze line of the left eye in the three-dimensional image space, and calculates a gazepoint in the three-dimensional image space as an intersection of the right gaze line and the left gaze line; and

    a processor that is in communication with the two or more video cameras, the stereoscopic display, and the binocular eyetracker and that determines a real target location by translating the gazepoint in the three-dimensional image space to the real target location in the three-dimensional real space from locations and positions of the two video cameras.
