Abstract
Abstract A system and method including a transparent display positioned between an object and an observer on which displays a superimposed data image transformed from structural data by calculating the parameters of a three dimensional matrix with information collected from position sensors. The mathematical parameters of the three dimensional matrix are defined in order to transform the structural image data into the perspective display data. Once the parameters of the three dimensional matrix are established, any points of the structural image can be shown on the display as a virtual image corresponding to the points on the object in real time.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
144 words
A method for displaying a moveable body in real time in three spatial dimensions, the method comprising the steps of: continuously tracking the position of said body, an observer, and a display unit relative to each other; continuously calculating a three-dimensional perspective projection of an image data representation of said body using data from the position tracking step; and displaying said projection of said image data representation on a display device to correlate the data representation to a perception of the body by the observer, said correlation comprising: matching the position, perspective, and scale of the data representation to those of a three-dimensional structural image of the body by detecting the body and presenting the structural image to the perception of the observer; and displaying the data representation on a transparent display device positioned between the structural image of the body and the observer.
Claim 2
Independent Claim
144 words
A method for displaying a moveable body in real time in three spatial dimensions, the method comprising the steps of: continuously tracking the position of said body, an observer, and a display unit relative to each other; continuously calculating a three-dimensional perspective projection of an image data representation of said body using data from the position tracking step; and displaying said projection of said image data representation on a display device to correlate the data representation to a perception of the body by the observer, said correlation comprising: matching the position, perspective, and scale of the data representation to those of a three-dimensional structural image of the body by detecting the body and presenting the structural image to the perception of the observer; and displaying the data representation on a transparent display device positioned between the structural image of the body and the observer.
Claim 3
Dependent Claim
41 words
The method of claim 1 further comprising providing a sensor for detecting relative motion between the body and an imaging device presenting an image to the observer for correlating the model to an image of the body perceived by the observer.
Claim 4
Dependent Claim
18 words
The method of claim 2 wherein the sensor is selected to detect motion in six degrees of freedom.
