Abstract:
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 and calculates an acceleration of the target from three or more real target positions determined over time.
