What is Virtual Reality?
• Also known by its acronym “VR”.
• Some define it as a “collection of technologies” [Isdale,
Jerry, “What is Virtual Reality? A Web-Based
Introduction”, page 2] like the head-mounted display,
data glove, and multimedia.
• Computer-generated artificial environment.
• Which is also known as a “virtual environment” or VE.
• Commonly used in games and engineering.
• Recently, VRML.



History of Virtual Reality
• Conceptualised by cinematographer Morton Heilig
in the early 1960s.
• Normal movies/pictures fill 18% of spectators’ vision,
Heilig wanted to change that by filling all 100% of it.
• No financial support for him, so he created this
“This virtual workstation utilized 3-D video, obtained with three
35 mm cameras mounted on the cameraman. The setup included
stereo sound, integrated with the full 3-D camera views. The
viewer could ride a motorcycle while sensing the wind, simulated
by a fan, and even potholes in the road. The machine was crude,
but it opened the door for a multitude of ideas - a whole new
world not yet discovered.” [Scott Tate, “Virtual Reality: A Historical
Perspective”]
[Scott Tate, “Virtual Reality: A Historical Perspective”]
• Finally, Ivan Sutherland of the University of Utah in the United States further
developed virtual reality in 1965.
• Initially experimented with three-dimensional displays.
• A system to surround viewers was developed, which became adopted by the US
Government for their space (Apollo) and military programmes (flight simulators).
• Where it is mainly used now, other than computer games.



Virtual Reality As A Communication Tool
• Why?
Text-based seems boring and plain. This would bring an ultimate experience!
• Allows natural interaction.
• May incorporate sensation, enabling users to feel each other or the objects
around.
• Example of one possible successful venture = There.Com (whose screenshots are below)

• More screenshots: http://www.thereuniverse.com/screenshots.shtml
(Well, I couldn’t get those here as they are really large in dimension)



Interesting points to note
•There is the digital divide.
•Internet connection speeds and infrastructure.
•Generally, loading times of these stuff is so SLOW! (But
if we follow Moore’s Law of computing power, technology
would surely catch up)
•Resources needed to upgrade the technology (BILLIONS
OF $$$!).
•Health issues.
•Security and privacy.



Implications of virtual reality.
•Uncomfortable headset.
•Putting on any headset, there is
ease of crime committed to the
wearer.
•“Immersion rooms” take up a lot of
space and cost lots of money.
•Especially the older generation,
many are unwilling to learn.
•Internet connections?

[Scott Tate, “Virtual Reality: A Historical Perspective”]



Conclusion
•Virtual reality might only be for the younger
generation.
•Interesting and exciting field.
•Security and privacy.
•Health issues still.
•Nothing beats real-life!
