2. What is VR?
●
A computer-simulated enviroment that can
simulate real physical world/interactions
which tracks the user in real time.
“So a virtual reality is a synthetic sensory experience which may one
day be indistinguishable from the real physical world”
-Kalawsky, R.S (1993)
3. Uses of VR
●
Architecture/Real-Estate(VR walkthrough)
●
Training (military,aviation,driving,ect)
●
Medicine/Health (treatment of PTSD,phobias,
phantom limb pain,
Amblyopia(lazyeye)/strabismus(crossedeye)
●
Engineering/Design (construction/blueprint)
●
E-Commerce (testing in VR before buying)
●
Entertainment(Fully immersive games)
●
Manufacturing (new products/goods)
4. Virtual Reality Systems
VR systems can be divided into 3 groups:
●
Non-immersive systems (like workstations)
●
Hybrid systems (aka Augmented reality systems)
●
Immersive systems (HMD or CAVE)
8. Oculus Rift (HMD)
●
The Oculus Rift is a Virtual Reality (VR) unit with
head tracking and 3D capabilities. It is still in
development but the goal is to bring a low cost,
highly effective VR unit to the average consumer.
10. Oculus Rift
●
Low Latency 360 degree Head Tracking
●
Stereoscopic 3D View
●
Ultra Wide 110 degree FOV(as far as the eye can see)
●
Has a gyroscope, accelerometer and magnetometer for no
latency Head Tracking
11. Oculus Rift
●
●
Omni by Virtuix
The Omni takes virtual reality to the next level— allowing anyone to
stand up and traverse virtual worlds with the natural use of their own
feet. The Omni is the first virtual reality interface for moving freely and
naturally in game. Moving naturally in virtual reality creates an
unprecedented sense of immersion that cannot be experienced sitting
down.
13. 3-D Internet
●
●
As the internet becomes intertwined with the real world, the resulting
Geoweb is another important stepping stone for the rise of the 3D
Internet.
Geoweb (or The ‚Geospatial Web’) stands for the merging of
geographical (location-based) information with the mainly abstract
information that is currently found on the internet.
14. Geoweb
●
●
Geowebbing is about a reordering of the internet around a geographic
interface. Geography and location become more and more important to
index information.
This creates an environment where people can search for things based
on location instead of by keyword only. The geoweb will allow users to
perform searches without even having a need to type in keywords –
one will be able to just browse around in a digital map.
15. VR Programming
Programmers have developed several different computer languages
and Web browsers. Some of these include:
●
●
●
●
Virtual Reality Modeling Language (VRML)- the earliest threedimensional modeling language for the Web. Huge demand for VRML
programmers in near future.
3DML - a three-dimensional modeling language where a user can visit
a spot (or Web site) through most Internet browsers after installing a
plug-in.
X3D - the language that replaced VRML as the standard for creating
virtual environments in the Internet.
Collaborative Design Activity (COLLADA) - a format used to allow
file interchanges within three-dimensional programs.
16. Future
●
●
1999 10% of the world's computing power was
non-human
2029
99% of the world's computing capacity
will be non-human
In the past, computing power has doubled
approximately every 2 years, a trend that is
known as Moore's Law. If this is the case, then
we should have computers powerful enough to
run immersive VR programs in every home by
the year 2037.
