Advanced display technology and the needs of the U.S. Department of Defense (DOD) and U.S. Department of Energy (DOE) were discussed during a two-day IPT meeting and workshop on advanced displays.

The Field of Light Display (FoLD) class of visualization systems provides true 3D without the need for special eyewear/glasses. Types within the FoLD class include: Holographic; Integral Ray (hogel-based); Integral Image (plenoptic-based), and Volumetric.

The FoLD class of information visualization systems all create 3D images without glasses and without the eyestrain and discomfort of the Stereo 3D (S3D) class. Some FoLD systems offer full parallax, meaning you can see around objects when moving your head left/right or up/down, and some offer horizontal parallax only. Two of the three display-focused teams that presented at this workshop are working on full parallax displays.
