Transcript of Virtual Reality

PLEASE PUT ON YOUR HEADSETS
INTRODUCING...
JARON LANIER
pioneering computer scientist
The man who introduced the
concept of Virtual Reality in
1987.
NOTABLE CONTRIBUTORS TO VIRTUAL REALITY
Douglas Engelbart
Ivan Sutherland
WHAT IS VIRTUAL REALITY?
Virtual is defined as “near” or in computing terms, “not physically existing, but software makes it appear to be existing”. Reality, is what we as humans experience. Combine the two together and we get “near human experience”.

OUR SENSES
SIGHT
TOUCH
HEARING
ARE HEIGHTENED
... BUT REALITY ISN'T PRESENT.
THAT IS
VIRTUAL REALITY.
Virtual reality stimulates our senses
with a computer generated environment.
Examples of Virtual Reality Technology

CAVE automatic virtual environments
Google Cardboard
Samsung GearVR
Epson Movario
Oculus Rift
Special gloves/datagloves


Advantages

Just like Skype, VR allows people to interact with another person more intimately.



You can see the prototype without actually building it therefore it is cost-efficient.
Decreases the divide for people with disabilities.
Disadvantages
VR is still in its developing stages.



The desensitisation of virtual reality
Cyber Addiction
Potential Virtual Criminality
Cybersickness
VR AND THE PRESENT
VR AND THE FUTURE
Food for Thought
“Will virtual reality become a reality for future generations?”
Possibilities of Virtual Reality are endless and is presently used for...
Video game industry
Large gaming market opportunities.

Low quality virtual reality headset - GearVR costs $99
High quality virtual reality headset - Oculus Rift costs $600
Data Visualization
Can be used to create virtual, interactive models.
For example, architecture or living things

Which can enhance visual communication
Military, Medicine and Pilot training
Alternative method for training employees with a realistic first-person viewpoint and even simulate a dangerous, high risk scenario.

In medicine, VR is used to replicate surgery operations for training.

It may eventually be possible for have patients go through a virtual experience of what to expect and what happens after an operation.

In pilot training (or aviation) 3D aircrafts can be used to train pilots. 3D aircrafts can also be used as prototype for airplane designers.

In the future it may be possible for other jobs that require a lot of skill, training such a police training or firefighter training


Treatment of Mental Illnesses
Allows for patients to overcome phobias and challenges in a controlled environment

Patients may experience a scenario similar to their trauma in attempt to overcome their fears

For example: PTSD
Cave Automatic Virtual Environment (CAVE)
A fully immersive room set up where users are able to enable with objects in an enclosed space.

The entire room is part of the virtual reality experience

However, the set up is expensive and is most just available for university and research companies/facilities
Will be available for consumer markets

Telepresence makes user feel as if they were truly present at a place other than their true location.




A full-body dive into virtual reality



Telepresence in Virtual Reality headsets
Would force the brain into a digital world.

A person's brain data would be uploaded into a network server.

Which may lead to permanently storing human memories and thoughts into various back-end systems.

It would also further the development for having users experience smell and taste of their surrounding virtual environments.
Innovation of Nanotech VR

Therefore...
There is lag reading user movements and loading time is slow.
There are some arguments that state that including violent actions in VR would desensitize the user, where they are no longer affected by the violent behaviour.
the more time spent in VR, the more likely the user cannot differentiate reality.
Users can be affected by other users in the virtual environment. This can cause emotional or even mental distress.
