Direct Retinal Display
Another term for a virtual retinal display, a direct 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.

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.
The 'virtual light' class of retinal displays, are perhaps unique in the display industry, because they don't actually display anything. The entire concept is built round bypassing the eye entirely, and dropping visual encoded information directly into the optic nerve.
Retinal display systems have been under development for many years with few successes. A new, and fundamentally different approach to the problem is now being trialled by researchers at the Technion-Israel Institute of Technology. Professor Shy Shoham and team are testing the power of holography to artificially stimulate cells in the retina of the eye, with the intent of bionically restoring vision. As a side-effect it would of course create a whole new class of retinal displays.
This still from Chrysalis shows a very different method of locking and unlocking your front door than we are used to. There is no key and no key hole. Instead, what there is is a retinal scanner embedded in the door level with the average head. Peer in and if it recognises you, it unlocks. If not, there is nothing to pick.
This shows what is essentially a full sensory immersion LAN. An eight person, totally self contained full-immersion VR machine. As shown, the interface method is direct neural biofeedback; the staple for the Matrix universe. Each of the person's brains are connected to the system via their brainstem, allowing full two way bodily sensory stimulus. However, there is no connection to the greater internet.
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.
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.
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.
The Argus devices, created by Second Sight Inc, are ocular implants designed to restore vision to those whose eyes no-longer function. For people whose sight loss occured as a result of outer retinal degenerations, such as Retinitis Pigmentosa, they offer a chance to see again, via arrays of electrodes connected to the back of the eye and the optic nerve.
