The document discusses virtual reality (VR) including its history, technology, applications, impacts, and barriers. It is presented by a team including Elijah, Xiao Nan, Kexin, Qi, and Darren. Elijah discusses the history of VR from early concepts in 1935 to recent developments. Xiao Nan explains the main components of VR systems including displays, audio, input devices, motion tracking, and software. Kexin discusses applications of VR in military, education, medicine, and fashion fields. Angela covers the positive and negative impacts of VR. Darren examines barriers to the success of VR in areas like innovation, simplicity, and compatibility with existing technologies and human behaviors.

3. What is Virtual Reality?
Presented by Elijah

4. VR is an emerging technology with a short but interesting past.
Important points of its history follow:
In 1935, US science fiction writer
Stanley G. Weinbaum described and
foreshadowed a concept like VR in his
story Pygmalion’s Spectacles (Dredge,
2016).
In 1961, Philco Corporation engineers developed
the first VR system with a head-mounted display,
called the Headsight (Strickland, 2016).
VR’s current importance began in 2010, when US
entrepreneur Palmer Luckey created a prototype VR
headset which would become the Oculus Rift (Dredg
2016).
In 1966, US computer scientist Ivan
Sutherland built the first VR head-
mounted display linked to a computer
system, instead of to a camera (Strickland,
2016).

5. Understanding of the Technology
Presented by Xiao Nan

6. • Commercialized VR systems have some main component categories.
• Within each category, different systems can have different components.
Oculus Rift HTC Vive Samsung Gear VR Sony PlayStation VR

7. • Have a slot to insert a smartphone,
which uses a software app
1. Sight
(hardware)
• Display the environment from video
sent from a console or computer
Provided by a head-mounted display
(HMD). Either:
Samsung Gear VR
Oculus Rift

8. • The VR app on the phone
2. Hearing
(hardware)
• The computer or console
VR systems use physical headphones
with the headset and either:

9. • For VR systems which use
smartphones, by a touchpad beside
the headset
3. Touch
(hardware)
• For VR systems which use consoles
or PCs, by controllers or smart
gloves
Allow user to have input and interact in
the simulated environment. Provided:

10. • Bodysuits
• Wired or wireless
controllers
• Positional
tracking
systems
• Omni-directional
treadmills
Motion allows users to move their
locations in 3D space. It is tracked and
transferred in several ways:
4. Motion tracking
(hardware)

11. • VR systems which use smartphones
require no more than the previous
5. Support
(hardware
& software)
• VR systems which use consoles or
PCs require either of these devices
to operate. The devices send video
to the headset
Both types of VR systems require a
software app.
For online apps, high-speed Internet
access is required.

12. Applications of Virtual Reality
Presented by Kexin

13. 1) Battlefield environment simulation
Battlefield environment simulations through VR’s 3D graphics library,
including combat scenarios and weapons and equipment training, can
create very realistic battlefield environments. Users can interact with
objects in the virtual environments to generate feelings and
experiences of "immersion" equal to real environments.
2) Training simulation
3)The development of weapons and equipment
Application of VR – Military field

14. 1) Virtual laboratory
The virtual laboratory is generated by VR technology of the test system
used for a virtual test. It includes laboratory environment, experimental
instruments, equipment, subjects, etc.The virtual laboratory can
experiment with both real and virtual laboratory designs
2)Virtual campus
Application of VR – Education field

15. 1)Virtual human body
In Germany, the University of Hamburg’s medical college used CT and MRT
cross-sectional images to create a 3D visualized virtual human body model,
and used virtual technology to establish a model of human organs. Such
virtual human bodies can undergo real clinical experiences according to
doctors’ decisions, and can make realistic relative responses.
2) Virtual surgery simulation
3) Telemedicine
Application of VR – Medical field

16. • 3D virtual dress systems
3D virtual fitting uses a computer simulation of the actual environment
for customers to try cloths. The 3D virtual fitting system has four
functions: choosing, fitting, displaying, and modifying clothes
3D clothing design can be performed through the virtual fitting system
based on certain human body models.
Application of VR – Fashion field

17. Impacts of Virtual Reality
Presented by Angela

18. Impacts of Virtual Reality
Positive Impact:
Ø Reduces costs.
(military, education,
etc.)
Ø Convenient.
Ø Revolutionary to our
everyday life.
Ø Accessible: low cost
or even free for a
pair of headset if you
pay for the shipping.
Negative Impact:
Ø Health: Cause dizziness after wearing/
uncomfortable headset.
Ø Phycology: Too obsessed with VR.
Ø Safety: VR Hazards.
Ø Legal: Lack of regulation of VR applications.

19. Barriers of Virtual Reality

Will it be successful?
Innovation
• There are many exciting uses for virtual reality.
• Sometimes sight is more practical.
Highly generic
• We use our eyes everyday.
• Virtual reality can substitute everything we use our eyes for.

21. 3

Will it be successful?
Simplistic
• Virtual reality is not hard to understand.
• It is technologically complicated.
Very compatible
• Virtual reality can easily replace activities that require sight.
• Again, sight is more practical in some circumstances.
