Virtual Reality Immersive Environments
[attachment=31710]
What is an immersive environment?
One that immerses the user inside of it.
Image/Projection does not have a frame.
Uses complete peripheral vision.
Peripheral vision is more sensitive than direct vision.
FOV ~ 180 degrees.
Gives a sense of being part of the scene.
HMD - Features
Portable viewing screens that add depth perception to otherwise flat images.
Two lenses through which you look at a viewing screens.
Two slightly different images are projected on the screen: one presenting the object as it would be seen the right eye, the other left.
These two stereo images are then fused by the brain into one 3D image.
BOOM™ - Interface
The buttons on the handle of eyeglasses provide an interface.
Other interfaces like a data glove can be hooked up to provide similar/advanced functionality.
CAVE - Features
In the CAVE, you are no longer on the outside looking in but on the inside looking out." - Thomas DeFanti, co-developer of the CAVE
CAVE Automatic Virtual Environment
> 180 degrees FOV
Usually 4 walls
Rear projection display
Each wall rendered at 60 FPS.
Two images per frame.
One per eye.
CAVE™ - Advantages
Unencumbered movement
No clunky helmets or viewing boxes.
The only required gear are a funky pair of glasses and a wand.
Large FOV
In an simulated environment the objects are not simulated just in front of you, but left, right, behind and above and through you.
What people are doing with VR
Virtual environments are helping researchers decipher the knowledge buried within the mountains of data that are piling up hourly, streaming out of space and earth-based instruments.
Scientists separated by a continent will be able to simultaneously share perspective on the data.
