Using <window>.screenToWorld within vizcave powerwall

How can one use the <window>.screenToWorld command within a vizcave powerwall?
Specifically, how can one get the length of the line passing through the given screen coordinates (in pixel units) with the begin point of the line being the users head position (center of the eyes)?

Unfortunately, the following code seems to be incorrect:
Code:
line = viz.MainWindow.screenToWorld([pixel_x,pixel_y], eye = viz.BOTH_EYE, mode = viz.WINDOW_PIXELS)
print line.length

Is the line length you want to calculate the distance from the user's head to a specific point on the physical wall?

I want to calculate depth information for each screen pixel in a way that for given 2d screen coordinates (x,y) I get the distance from the user's head to the point in the 3d scene that corresponds to the given 2d screen coordinates. Ultimately, the goal is to construct a "depth map" for a scene given the user's head position and gaze direction.
