360-Degree Fog Projection Interactive Display

The ultimate goal of our project is to construct a 360-degree observable 3D fog display which realizes interaction between observers and presented objects. Previous fog displays use a single projector with a flat fog screen. Our proposed display uses multiple projectors, each showing a different picture from a different viewpoint. Though all images are projected on one cylindrical fog screen, the fog shows Mie scattering that creates the forward scattering of projected images. When the observer walks around the fog screen, the fog acts like a parallax barrier and shows one image to the observer at a time. In this way, the 3D shape of the object can be recognized from the motion parallax.
Most 3D displays cannot enable touch of the virtual object because the projection system is covered and sometime dangerous. One of the advantages of fog screens is that the observer can interact with the virtual objects by hand. Our 3D fog display lets observers handle the virtual object directly without danger. We use IR LED on the fingertip and the IR camera to detect the motion of observer's hand.
This display has many interesting future applications in the fields of entertainment, medical visualization, digital signage and 3D telecommunication.
