Researchers from Osaka University have created an interactive fog display with multi-viewpoint observation. This system utilizes the fact that dispersion of light by fog has directionality. It projects different pictures, from different angles, onto a cylindrical fog screen. Thus the 3D objects can be recognized from the motion parallax, which is how the view of objects changes depending on the viewpoint. Continue reading for two videos and more information.
According to the lead researcher, "The starting point for this project came when we saw a fog display in an amusement park, and wondered if we could come up with something more interesting. As future developments, we hope this system will find applications in healthcare and entertainment. We'd also like to find more useful content, and improve the configuration to make the fog display a bit more stable."
