Towards VR and AR enhancement: light field display with mid-air interaction.

We present a 360° light field display to visualize 3D objects above the table-top screen, and provide a graspable and measurable virtual or augmented reality environment. The display is constructed by a spinning flat-plate deflected diffuser screen, a high-speed light field projector, and the user tracking and interaction components. A rear projection light propagation is specially designed to reconstruct the light field. By calibrating this levitated light field to the physical dimension, and capturing user gestures, we enable multiple users mid-air interactions based on their virtual measurement perception.
