Immaterial display allows viewers to handle 3D images in air

(PhysOrg.com) — In the future of immersive entertainment, people may not only walk through floating 3D images, but also manipulate the images in thin air. Taking a step toward this reality, researchers have built a prototype of a room-sized 3D immaterial display, demonstrating the possibility of using the technology for a variety of entertainment purposes.
In recent years, 2D FogScreens have gained popularity at entertainment venues. Desktop-sized and handheld DFD displays also exist, although users are restricted to a single viewpoint. In a room-size DFD display, users could stand anywhere, and wouldn’t need to wear 3D glasses, to view 3D images.
“The biggest advantage to DFD rendering lies in the fact that observers do not have to wear encumbering glasses to view the 3D scene,” Lee told PhysOrg.com. “Although traditional auto-stereo displays and volumetric displays also exhibit this quality, their inherent technology limits their usability. Autostereo displays allow for a limited number of views, and volumetric displays are usually enclosed within some space which users cannot or should not interact with. DFD displays allow for many views and interaction as long as a user is reliably tracked.” more>>>
