This document discusses virtual reality, including its definition, history, components, applications, current trends in Hong Kong, results from an online survey, future developments, problems, and conclusion. It defines virtual reality as an artificial environment created with software that users accept as real. The document outlines the evolution of VR technology from panoramic paintings in the 19th century to modern head-mounted displays. It describes the hardware and software components of VR and provides examples of its applications in business, training, education, medicine, and entertainment.

3. Definition Virtual reality
is an artificial environment that is created with
software and presented to the user in such a way that
the user suspends belief and accepts it as a real
environment.
On a computer, virtual reality is primarily experienced
through two of the five senses: sight and sound.

4. History of Virtual
reality
Early attempts (19th century)
➢ Panoramic paintings
○ 360-degree murals1929 – Link Trainer The First Flight Simulator
➢ the first example of a commercial flight simulator
1950s – Morton Heilig’s Sensorama
1960 – The first VR Head Mounted Display
1987 – Naming of "Virtual reality"
➢ Jaron Lanier, founder of the visual programming lab
(VPL), coined (or according to some popularised)
the term “virtual reality”
1993 – SEGA announce new VR glasses
1995 – Nintendo Virtual Boy
21st century
➢ Computer technology; video game industry;
➢ Google cardboard; Samsung Galaxy Gear; Oculus
Rift; PS4

5. Virtual Reality
Component
Virtual reality classified into 2 major categories:
1. Hardware:
➔ Sensory Displays
➔ Computer
➔ Process Acceleration Cards
➔ Tracking System
➔ Input Devices
1. Software:
➔ modeling tools
➔ development tools (include software system)

7. Hardware

8. Software The tools can be classified into modeling tools and
development tools.
VR Modeling Tools: available for VR designing,
the most common : 3Ds Max, Maya and Creator.
Engineering specific applications might use software
like CATIA, Pro/E, Solidworks, UG, etc.
VR Development Tools: Real time 3D computer
graphics, tracking technology, sound processing and
haptic technology
flexibility and real time interaction is needed
collection of tools and software for
designing, developing and maintaining
virtual environments and the database
where the information is stored.

9. 1.Non-immersive
VR system
(Desktop VR
system)
-least immersive
-least expensive
-least sophisticated components
interact with a 3D environment :
a stereo display monitor and glasses
data gloves
→ see the information about the real world, present
via computer
→ located based service, GIS
J. Isdale, What Is Virtual Reality? A Web-Based Introduction, Version 4, Information on
http://vr.isdale.com/WhatIsVR/frames/WhatIsVR4.1.html
VR system:
Like Workstation

10. 2.Immersive VR
system
-the most expensive
-the highest level of immersion
its components include
HMD
tracking devices
data gloves
encompass the user with computer generated 3D
animation
-feeling of being part of virtual environment
-stay in the real world but see the simulated object
LIke HMD

11. 3.Semi-immersive
VR system
(hybrid system/
reality system)
high level of immersion
-see simulated world and “be” in that simulated world
Example of these system:
CAVE (Cave Automatic Virtual Environment)
driving simulator
Like Cave

12. Application of
Virtual Reality

13. Application:
Business
Business:
-virtual tours of business environment
-training new employee
-360 view of product

14. Application:
Training
Training:
-flight simulators
-sports training
-battlefield simulators for soldiers & paratrooping
-Transportation (e.g: bus driver/ MTR )
-doctor skill training

15. Application
Education:
Education:
-situation training
-lesson (learn to interact with disability student)
-increase teaching efficiency (participation; attractive)
→ increase comprehension and enhance interest
-cinema (watch the movie themselves)

16. Application:
Medical
Medical:
-surgery simulation
-phobia treatment (abnormal treatment)
-anxiety disorder treatment
-handle of nursing/ dentistry
-training for professional doctor/ nurse

17. Application:
Entertainment
Entertainment:
-game (PS4)
-virtual theme park
-virtual museum
-movie

18. Application
Engineering and
Design
Engineering and design
-understand the facilitates change
-reduce the time ( design process)
-cost factor (decrease)

19. Virtual Reality in
Hong Kong (Trend)
Party room: V-Owl Station VR Party
omnidirectional gaming treadmills (HTC vivie
only)
Playdium VR,experience studio” in Causeway
Bay (zombie death)
Konsept VR 32: VR + aerial machine

20. Survey Online Survey
Target: student
Information: experience and opinion about VR

21. Survey analyze -All of them only play VR game before
➔ VR game & VR game trial
➔ Easy to buy VR game and its equipment
➔ Medical & training VR mostly provide for
professional

22. Survey analyze -most of them believe VR will become
future trend in Hong Kong and they
prefer VR gonna be used on
entertainment
➔ Student used to play game rather than
another purpose
➔ VR game provide a better playing experience
➔ VR game is more attractive

23. Virtual Reality
future development
1. Mobile VR (eg: pokemon GO)
2. Impact all the sensory → not only visual and
auditory senses, but also feel bodywise,
temperature-wise, and smell
3. More people / categories use VR
4. AR mix VR
5. Live broadcast (don’t need to record in
advance)
6. Real estate real scene ()

24. Virtual Reality
problem
1. Motion sickness
→ (neurological effect)when exposure to a virtual
environment cause syndrome that similar to motion
sickness
→ shake the nausea, headache and drowsiness
→ women are susceptible than men
1. Effect your eye
→ long time to watch the sensor cause myopia
1. Less physical movement
→ require less movement to use VR cause physical
health problem
→ similar place but the physical movement are not
same

25. Conclusion Virtual Reality
Future human development
