Retinal Image Size
When the real size of the object is known, our brain compares the sensed size of the object to this real size, and thus acquires information about the distance of the object.

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.
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.
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.
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.
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.
The above image from a mixed reality conference ? split between a physical location and a single virtual world ? illustrates yet again the problem with packing a large number of avatars into a single, small virtual space, under current technological approaches.
This image is all about mapping, and more specifically how to preserve all necessary high level information in a virtual environment, in a cut down form, to allow easy oversight.
This image shows the output from a tiny broadcast drone one of the runner robots in Matriculated, literally excremented out of its posterior. It sunk into the ground and then began transmitting this simplified image. The reason being that all these machines see reality and virtual reality as interchangeable. As one of the characters said, and its true "all reality is virtual to them". So, when summoning reinforcements, keep it as simple as possible.

An interesting site, covering compuer learning, and the methods employed to develop systems that learn from their mistakes. It's still growing, and, whilest possibly a bit disorganised, it's a healthy size.
