Interactive Volumetric Fog Display from miu on Vimeo.

In this project, we developed two sets of volumetric display that apply projection mapping to a non-planar and reconfigurable fog screen, thus enabling interactive visual contents to be displayed at multiple depth levels. Viewers can perceive the three-dimensionality naturally and interact with the unencumbered images by touching them directly in mid-air. The displays can be used in mixed reality settings where physical objects co-exist and interact with the 3D imagery in physical space in real time. They do not require special glasses, head-mounted devices or eye/head-tracking, while allowing high-resolution, full-color 3D image to be observed from wide viewing angles by many people at the same time. Most importantly, our immaterial, mid-air displays will allow users to intuitively touch and manipulate virtual objects in 3D under marker-free and barrier-free settings, which will open up immense tangible and creative interaction possibilities.
