3. Let's prep first...
WHAT IS REALITY? WHAT DO YOU MEAN BY
VIRTUAL?

4. Virtual Reality (VR)
Virtual Reality (VR) is a computer-generated environment with
scenes and objects that appear to be real, making the user feel
they are immersed in their surroundings.
OR
VR Refers to generating a virtual environment or projection
which creates a realistic experience but does not exist in reality.

5. Examples of VR: Virtual Cycling

6. Examples of VR: Virtual Museum Tour

7. How Does Virtual Reality (VR) Work?
• VR systems work by simulating as many senses as possible to trick the
human brain into perceiving the virtual environment as reality.
• Special Hardware components are used in VR:
• Head-mounted Displays (HMDs)
• Headphones with special audio
• Gyroscopes, accelerometers and magnetometers for head and motion
tracking
• Controllers, gloves and treadmills

12. How it started...

13. History of VR
• 1930s – Science fiction story predicted VR
The idea of a pair of goggles that let the
wearer experience a fictional world
through holographic, smell, taste and
touch.

14. History of VR
• 1950s – Morton Heilig’s Sensorama
An arcade-style theatre cabinet that
would stimulate all the senses, not only
sight and sound.

15. History of VR
• 1960 – The first VR Head Mounted
Display by Morton Heilig
Telesphere Mask (patented 1960) and was the
first example of a head-mounted display (HMD),
albeit for the non-interactive film medium
without any motion tracking.
• 1961 Headsight – First motion tracking
HMD by Comeau & Bryan
Incorporated a video screen for each eye and
a magnetic motion tracking system, which was
linked to a closed circuit camera.

16. History of VR
• 1965 – The Ultimate display by
Ivan Sutherland
It simulates reality to the point where one could not tell
the difference from actual reality.
It included
• A virtual world viewed through a HMD
• Computer hardware to create the virtual word
• The ability users to interact with objects in
the virtual world.

17. History of VR
• Beginning of VR: Jaron Lanier
• Coined the Term ‘Virtual Reality’
• Created one of the first companies that sold VR
based products
• Considered one of the most influential computer
scientists in VR history

19. Types of VR
Non-
Immersive
VR
Fully
Immersive
VR
Semi
Immersive
VR
Collaborative
VR

20. Non Immersive
VR
• Computer-generated
environments without the feel of
immersion.

21. Fully Immersive
VR
• Give you a sense of being
present in that
virtual world and everything is
happening to you for real.
• Involves helmets, gloves, and
body connectors with sense
detectors.

22. Semi Immersive
VR
• A mixture of non-immersive
and fully immersive virtual
reality.
• Provides users with a
partially virtual environment.

23. Collaborative VR
• Allows users to collaborate
in virtual reality from
remote locations.
• The goal of this form of VR
is to create collaboration
between people.

VR System Architecture

26. How Does VR Work?
• A head-mounted display (HMD) is put on by a user, the screen then
moves along with the users head movements to create a simulated
environment.

27. How Does VR Work?
• VR headsets use either two LCD displays
or have two different feeds being sent to
one display.
• Lenses that are placed between the
screen and a user's eyes so images can be
focused and reshaped.
• This creates a stereoscopic 3D image by
combining the different images.

28. Characteristics of
VR
• Interaction
• Imagination
• Immersion
