The Fresnel Effect

An effect used when dealing with the creation of realistic reflective surfaces, and the physics that go along with them, the Fresnel Effect was first documented in the physical world by the French physicist Augustin-Jean Fresnel.

In order to look realistic, reflections change as you approach them from different distances. This is why using static textures as ?reflections? never really works.

In reality, the angle between you and the surface of the object that you are looking at affects the amount of light that is reflected and refracted that you can see. For example, if you look at a lake from a far-off distance, it will appear almost completely mirror-like, yet, as you get closer, and the angle at which you are seeing the water widens, the water appears less reflective and more transparent.

Looks more important than Sounds in Speech
A neurological experiment has confirmed that the McGurk effect - a long-known phenomenon where what you see overrides what you hear - is indeed codified directly into the sound processing regions of the brain. Meaning the McGurk effect is not something that can be barpassed in our virtual environments, and is not a trick of sensory perception, but rather is a cornerstone of sound perception itself.

Imagination Eases Pain: Study Reinforces Effect Shown by VRs
A study has been performed on the use of imagination in children as a pain blocker. Whilst not directly connected with VR in pain relief itself, the results do serve to reinforce the position that diverting the child's attention elsewhere during a procedure, utterly diverting it and holding that diversion, is successful in removing the effect of pain.

A detailed, in-depth look at why selling content from within MMOs, to others can damage the business on the company in question, by looking at the effect it has on the costs of the MMO.

Large Image Display: Animatrix: Beyond: Indoor, Cloudless Rain
Like most of the screens from Beyond, this one shows an effect of what happens when the laws of a virtual environment become too complex, and interactions go a little ca ca. In this case, a torrent of downpour, inside, on a sunny day.

Why Recoil at Unpleasant Noise Occurs
Nails on a blackboard. It is an unbearable noise, one that sends shivers through anyone who hears it. But why does it do this, and more importantly, how can a virtual environment replicate the effect in any sound?

It's the End of the World as we Know It
Dealing with disappointed players is one of the most important skills for a storyteller. No matter what you do, somebody will be disappointed with the result, and may leave, or worse. This short article covers several real example problems, and the steps that can be taken to lessen their effect.

VR Interfaces: Vivid Cyber Sex Suit

A mis-fire in the teledildonics industry, this early attempt at sexual stimulation in VR fell short after it was discovered it had a minor side effect - bodily secretions caused a lethal electrical discharge.

VR Interfaces: Fogscreen
Fogscreen is a holoprojection method that utilises a layer of artificially fogged air as a display screen for projected content. It in effect, creates a cascading curtain of wet air that can be walked through whilst displaying moving, bright, images.

Virtual Limbs: Living with three arms
Virtual Reality is just beginning to head down the full body sensation reproduction path. We are at the very early stages of being able to recreate parts of the physical form, entirely in the virtual. This is a concept which is likely to have very a profound effect upon how we deal with the world around us.
