Interactive Volumetric Fog Display

SIGGRAPH Asia 2015 Emerging Technologies We present a novel 3D display that applies projection mapping to a non-planar and reconfigurable fog screen, thus enabling interactive visual contents to be displayed at multiple depth levels. Users can perceive three-dimensionality naturally and interact with the unencumbered images by touching them directly in mid-air. The display can also be used in mixed reality settings where physical objects can co-exist and interact with virtual objects in physical space in real time. It does 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 display 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.
