BiDi Screen: A Thin, Depth-Sensing LCD for 3D Interaction using Light Fields

Matt Hirsch, Doug Lanman, Henry Holtzman, Ramesh Raskar

Abstract

An LCD screen is transformed into a BiDi (bidirectional) screen to support 2D multi-touch and walk-up 3D gesture interaction. An image sensor placed a small distance behind an LCD forms a mask-based light-field camera, allowing passive depth estimation. The BiDi screen also supports novel mixed-reality rendering with external light-emitting widgets that light a virtual scene.
