Distant Focus

In VR interfaces, a distant focus is the artificial blurring of ?nearby? objects when the system detects the user is trying to focus on those further away. Whilst processor intensive and requiring additional sensor capability, it works to increase the feeling of immersion, by mimicking natural eyesight behaviour.

A trick that is necessary is a fast responsive system able to switch close objects back into focus at the first flick of eye movement.

The Omni-focus
The omni-focus is a camera system with the ability to function much like the human eye - capturing objects in its field of vision regardless of the distance, in perfect focus. It even adapts an algorithm from VR, in order to do so.

Cameras Without Lenses
It sounds odd to think of cameras without lenses to focus the light, because cameras have continually been created with intent to replicate the eye, and the eye has a lens. Without a lens, how do you focus light? Well you don't, but that's ok, because you don't have to.

The First Neural-Jack?
Japanese researchers have created the very first, incredibly crude, neural-jack interface, a distant ancestor of those seen in cyberpunk and the Matrix films, but of the same lineage all the same.

Beating the Limitations of Camera-Monitor Mediated Telepresence with Extra Eyes
When interacting physially, you are most aware of your immediate surroundings, and less aware of objects further away. In telepresence that is usually reversed, as the telepresence screen you focus on concentrates itself on objects far away. Is there any way to combat this? Perhaps...

Attention is what makes Sensory Data Stand Out
The title above should come as no surprise to most people. However, we now have empirical scientific evidence to back this up. When you concentrate your attention or focus on a particular channel of sensory input, it comes in clear and sharp, regardless of the background information. The study focuses on the sense of sight, but what applies there, applies to all.
