Virtual Retinal Display

A Virtual Retinal Display or VRD – occasionally called 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.

As such it bypasses the focussing mechanisms of the eye, and thus avoids any eyestrain or muscle ache no matter how long a period the display system is used for. The display itself handles focussing, so the eye is free to focus as it wishes to, to focus on an image which appears to be further away. In principle the technology can provide full-colour, high-resolution dynamic displays, that feel utterly real in palette.

VR Interfaces: Virtual Retinal Display

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.

VR Interfaces: Boston Retinal Implant Project
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.

A new route to Retinal Displays - Holographic Lenses
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.

Large Image Display: Chrysalis: Optical Door Locks
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.

Resource List: Virtual Sight Devices

Virtual sight devices, sometimes termed virtual light, are a class of display system which is a mix of AR, prosthetics, and VR. They have no actual display units as such, and completely bypass the human eye. Instead, they tap into the optical nerve directly, and deliver processed information to the neurons heading into the brain.

Perspecta: Volumetric 3D Display

The Perspecta display system was released by Actuality Systems in May 2005. Its intended purpose is as a 3D volumetric display capable of projecting a virtual object right in front of you.

Large Image Display: The Stepford Wives: Blending Displays with Drapes
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.

VR Interfaces: Perspecta
A technical look at the Perspecta suspended display system, released by Actuality Systems in May 2005. Its intended purpose is as a 3D volumetric display capable of projecting a virtual object right in front of you.

18-Foot Wide Super-HD Multi-User Multitouch Display
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.
