BiDi Screen, 3D gesture interaction in thin screen device

Coo demo of a 3d display with multitouch and off-screen gestural control.

We transform an LCD into a display that supports both 2D multi-touch and unencumbered 3D gestures. Our BiDirectional (BiDi) screen, capable of both image capture and display, is inspired by emerging LCDs that use embedded optical sensors to detect multiple points of contact. We exploit the spatial light modulation capability of LCDs to allow lensless imaging without interfering with display functionality.
