Dear all, How about having a camera on the same optical path of the user eye (using a beam splitter) that would chose for every pixel the best color/intensity to apply to the drawn pixels according to what is behind? A color inverting scheme similar to the one found in Windows for the cursor could be applied. For example, a pixel to draw in white would be black on a white background and white on a black background. Of course this works very good with white drawing and I am not sure right now how to extend it for other-than-white drawing, but that's an idea.
