32.4: A Scalable, Collaborative, Interactive Light‐field Display System

Abstract

Light‐field displays provide a visual sense of presence by producing a full‐parallax three‐dimensional aerial and virtual image of portrayed subject matter that satisfies multiple depth cues and that can be engaged naturally and intuitively. This paper documents a comprehensive light‐field display system, including computation, photonics, and interaction system components, that is flexible and scalable, establishing a basis for application to both large‐scale collaborative and portable, mobile product architectures.

The Road Ahead to the Holodeck: Light‐Field Imaging and Display

“…A video display produced by Zebra Imaging based upon this architecture will be the described at the SID Display Week Technical Conference in May in Vancouver. 13 To focus the eye at any arbitrary depth within the reconstructed volume, more than a single ray from every surface point in the virtual volume must be included in the bundles of rays passing through the viewer's pupil for every possible eye location within the viewing space. This is the data that is captured by the plenoptic camera.…”

“…light-field video display described in Ref. 13 provides parallax and unique s3D information for every viewer location, but lacks sufficient rays to support arbitrary focusing.…”
