AI Technical Summary

Benefits of technology

"The invention provides a system and method for creating a multiple-display video system using virtual cameras and a rendering image processor. The system can display different scenes and viewpoints simultaneously on multiple screens, reducing the amount of bandwidth needed for real-time animation effects. The screens can be physically sited to create a single large display or directed to display different scenes and viewpoints, creating a seamless visual experience. The system can also be used to display local data, such as airline arrivals and departures, on the screens. Additionally, the invention can be used to create an autostereoscopic display by illuminating large lenticular arrays."

Problems solved by technology

Further, much of the prior work requires shuttered or Polaroid glasses on the viewer for stereoscopic output.
Further, the treatment of animation graphics across multiple displays currently requires extremely high end, custom hardware and software and large bandwidth capability.

Embodiment Construction

[0027]FIG. 1 illustrates a representative layout of a contiguous video projection array according to the invention, the illustrated embodiment being an airport terminal display system that displays animated graphics and a text data overlay from a flight information data system (FIDS) database. In FIG. 1, the video projection array system, indicated generally at 10, includes a main server 12 which accepts FIDS data or data from any other text source, such as may be presented in Oracle or SGL, through an internal Ethernet port 14 as joined by a high speed switching hub 16. The hub 16 makes it possible for multiple sourcing of the FIDS data for several isolated imaging arrays, only one such array 10 being shown in FIG. 1. The preferably UNIX-based main server 12 transceives data through a series of separate switching Ethernet hubs 18, 20 and 22. Each of the hubs 18-22 is directly linked to one or more groups 24-28 of imaging or rendering computers 38-50.

[0028]Each of the hubs 18-22 has...

Abstract

An autostereoscopic display system includes a lenticular lens display screen that projects a plurality of views of a scene from its front surface. A plurality of video projectors are disposed to the rear of the display screen and focus on a convergence point of the display screen's rear surface. Imaging computers drive the video projectors, each having a memory storing a scene to be displayed on the display screen. Each computer renders the scene from a preselected viewpoint that may be different from the viewpoints of the other imaging computers.

Description

RELATED APPLICATIONS[0001]This application is a continuation of U.S. patent application Ser. No. 10 / 955,339 filed Sep. 24, 2004, which is in turn a division of U.S. patent application Ser. No. 09 / 921,090 filed Aug. 2, 2001, the specification of which is fully incorporated by reference herein.BACKGROUND OF THE INVENTION[0002]As display screens have grown in size and fineness of resolution, investigators have experimented with placing several such display screens adjacent to each other and causing three dimensional graphical data to be displayed on them. In 1992, the University of Illinois introduced a multi-user, room-sized immersive environment called the Pyramid CAVE (for “CAVE automatic virtual environment”). Three dimensional graphics were projected onto the walls and floors of a large cube composed of display screens, each typically measuring eight to ten feet. The cubic environment uses stereoscopic projection and spatialized sound to enhance immersion. Computers and display sy...
