A spatial display is any display hardware which is capable of giving the illusion of physical depth. Most often this is accomplished through stereoscopy, although holographic and parabolic display media are also used.

How do you perceive space and spatial relationships between objects in a virtual environment. Rather easily if you are setting out to replicate the physical world. But that is too easy, it loses so many of the true advantages of VR, where space is irrelevant, and every room can be a TARDIS. This article looks at mapping that kind of a mess, beginning with text worlds, where such spatial irrelevancy is at its highest.
There are several potential ways this display is working. One of the simplest and most plausible is a colour e-paper display behind a completely transparent display medium. The e-paper handles the picture, 'refreshing' the colour display to a matt black when the layer in front, the graphical display is activated. As soon as that deactivates, the 'oil' is re-drawn. Simple, elegant, and still far beyond us.
VRD or Virtual Retinal Display is an offshoot of HMD display technology, which, instead of placing a pair of display screens in front of the eyes, actually projects an image directly onto the human retina with low-energy lasers or LCDs.

MR Aquarium was demonstrated in 2008, as a spatial VR project using multiple magic symbol displays on walls and pedestals, to bypass the problem, of turning the HUD away from the magic symbol, at which point the AR disappears.
The brain is built to handle such a 3D world, and employs a number of tricks to counter disorientation. These are tricks we can utilise in 3D spatial simulations, to help minimise disorientation there; but first we have to understand what the brain's tricks are, and how they operate.
On September 8th 2009, Obscura Digital installed the first display of its kind, at the Hard Rock cafe in Las Vegas, US. This display is a dynamically resizing, dynamically multi-user, multitouch display wall.
First printed in 2005, this book?s techniques are not exactly the cutting edge in terms of AR practices ? it hails from the first days of AR?s emergence. Even so, it is very comprehensive, and leads the reader from the first simple introductions, up to actual implementation of augmented reality for practical applications in immersive education and entertainment.
A quote about a holo-display in a rosewood cube, casts an accurate picture of how display technology can be worked into everyday things, to make it a part of life.
