The Tangible3D project will create the first interactive tactile true-3D displays that integrate the complete light field 3D space, with all parts of the scene directly available for interaction (from Holografika) with a non-contact tactile system that allows users to feel the objects in mid-air (from Ultrahaptics). The 3D display system will allow users to reach into the viewing volume to touch virtual objects, and even feel gradients of haptic feedback as the hands penetrate into virtual objects.
