A target is imaged in a three-dimensional real space using two or more video cameras. A three-dimensional image space combined from two video cameras of the two or more video cameras is displayed to a user using a stereoscopic display. A right eye and a left eye of the user are imaged as the user is observing the target in the stereoscopic video display, a right gaze line of the right eye and a left gaze line of the left eye are calculated in the three-dimensional image space, and a gazepoint in the three-dimensional image space is calculated as the intersection of the right gaze line and the left gaze line using a binocular eyetracker. A real target location is determined by translating the gazepoint in the three-dimensional image space to the real target location in the three-dimensional real space from the locations and the positions of the two video cameras using a processor. |
