How To “Touch” That 3D Character In Front of You…
“Here’s a 3D screen of a different kind: a research team at Japan’s Keio University has developed a display that allows users to “touch” virtual 3D characters.
The way the so-called RePro3D works is that it combines a naked-eye, full-parallax 3D display with a tactile interface that lets users manipulate virtual objects in a 3D environment with their fingers.
The makers explain:
RePro3D is a full-parallax 3D display system suitable for interactive 3D applications. The approach is based on a retro-reflective projection technology in which several images from a projector array are displayed on a retro-reflective screen. When viewers look at the screen through a half mirror, they see a 3D image superimposed on the real scene without glasses.”
