We present a novel walk-through pseudo-3D display, which enables 3D interactionand interesting possibilities for advanced user interface designs. Our work isbased on the patented FogScreen, an “immaterial” indoor 2D projection screenwhich enables high-quality projected images in free space. We extend the basic2D FogScreen setup with stereoscopic imagery and two-sidedness, in addition tothe use of head tracking to provide correct perspective 3D rendering for a singleuser. We also add support for 2D and 3D interaction for multiple users with theobjects on the screen, via a number of wireless input technologies that let us experimentwith interaction with or without encumbering devices. We evaluate theusability of these interaction techniques by observing non-expert use in real settingsto quantify the effects they have on 3D perception. The result is a wall-sized,immaterial pseudo-3D display that enables engaging 3D visuals with intriguing3D interaction.
