Recently the Defense Advanced Research Projects Agency (DARPA ) completed a five-year program called the Urban Photonic Sandtable Display (UPSD). This Display creates a real-time, interactive, 360-degree, color 3D holographic view to assist military battle planners without the aid of 3D goggles or glasses.
The large-format interactive 3D display platform is scalable, allowing for expansion from six-inches all the way up to six-feet diagonal in both full color and monochrome formats. UPSD is based on full-parallax technology , which enables 3D holographic objects to project the same amount of light in 360- degrees that the original object has and allows for full visual depth capabilities up to twelve inches. The holographic display permits simultaneous viewing and interactivity for up to 20 individuals, allowing the image to be frozen, rotated, and zoomed. Other 3D displays currently available lack full-parallax technology, providing only 3D viewing from certain angles and only three to four inches of visual depth.
DARPA will be initially using the UPSD technology at one Air Force and two Army research centers where the 3D holographic display will provide a unique benefit. In the future I can see great uses of this technology in education, especially for the medical and engineering disciplines. Let us know what you think of this technology and how you might be able to utilize it within your own discipline.
