1. A projection display system comprising:

  • projector means for projecting an image beam;

    a front projection image screen for making the image beam visible as an image;

    a transparent-reflective panel disposed so the image beam from the projector means strikes the transparent-reflective panel and is transmitted therethrough to reach the front projection image screen forming a visible image, the transparent-reflective panel angled relative to the front projection image screen for reflecting the visible image formed thereon so that an observer gazing toward a front projection image screen-facing side of said panel will perceive a reflection of the visible image as appearing at a distance beyond the transparent-reflective panel;

    a supporting structure for ensuring proper alignment between the projector means, the front projection image screen and the transparent-reflective panel, the projector means mounted upon the supporting structure with the image beam directed through the transparent-reflective panel to the front projection image screen so that the reflection of the visible image formed on the front projection image screen appears to the observer to be located above a working surface utilized by the observer while in a seated position; and

    a camera mount for mounting a camera behind the screen-facing side of said panel for capturing images of the observer through said panel for transmission to a distant display system.
