Volumetric Display for Augmented Reality

In our previous paper, we proposed an augmented reality display based on the pepper's ghost configuration that was able to display two-dimensional images on different image plane at different physical depths. In this paper, we propose the next generation of the display. Our latest display is able to display images at different physical depths simultaneously, thus it is able to display virtual objects with real depth, binocular parallax and motion parallax without the use of special glasses. Using the pepper's ghost setup, we are able to display real world objects and virtual objects in the same space. Furthermore, since the rendered virtual objects have real physical depth, our system does not suffer from accommodation and convergence mismatch problem. We will describe the hardware setup, software system, and follow with two user evaluation experiments that evaluated the result of our system.
