摘要

LCD屏幕被转换成BiDi(双向)屏幕，以支持2D多点触摸和步行3D手势交互。图像传感器放置在LCD后面一小段距离，形成基于掩模的光场相机，允许被动深度估计。BiDi屏幕还支持新颖的混合现实渲染，使用外部发光小部件照亮虚拟场景。

BiDi screen: a thin, depth-sensing LCD for 3D interaction using light fields

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.
