👓 Introduction to Augmented and Virtual Reality
This paragraph introduces the two trending technologies: augmented reality (AR) and virtual reality (VR). It explains that people often confuse the two but promises to clarify their differences. The example of IKEA’s app is given, which allows customers to visualize how furniture would look in their homes using AR. Similarly, Snapchat is cited for its AR filters, where users add digital content to real-time images. The key point is that AR overlays digital elements on the real world to enhance user experience, while blending both realities.
🌍 Exploring Virtual Reality
This section explains virtual reality (VR) as a technology that immerses users into a simulated environment, allowing them to experience places like hillsides, the moon, or the ocean. VR works by engaging multiple senses such as vision, hearing, and touch, offering a sense of presence in a virtual world. The concept is summarized as computer technology creating environments where users feel they exist.
📜 A Brief History of Augmented Reality
A brief history of AR begins with the first head-mounted display, 'The Sword of Damocles,' invented by Harvard professor Ivan Sutherland in 1968. It allowed users to experience computer-generated graphics. In 1990, the term 'augmented reality' was first coined by researcher Tom Caudell. These developments marked the beginning of AR technology.
📜 A Brief History of Virtual Reality
This paragraph explores the history of virtual reality (VR), starting in 1957 when Morton Heilig, a cinematographer, created Sensorama, the first virtual reality machine. Sensorama combined several technologies to engage multiple senses, such as video, audio, vibrations, and even smell. In 1987, researcher Jaron Lanier coined the term 'virtual reality,' setting the foundation for the technology.
🆚 Comparing Augmented Reality and Virtual Reality
Here, the key differences between AR and VR are outlined. In AR, a digital layer is superimposed on the physical world, blending the two, while in VR, users are fully immersed in a simulated virtual environment. AR allows users to clearly distinguish between the real and virtual worlds, whereas VR makes it difficult to differentiate between them. AR can be accessed through devices like smartphones and tablets, while VR requires specialized headsets and equipment.
🏥 Applications of Augmented and Virtual Reality (Part 1)
The paragraph highlights several practical applications of AR and VR technologies. In healthcare, they are used by doctors and technicians for various medical purposes. In military training, they help create virtual environments for training soldiers. Education also benefits from AR and VR, enhancing students' understanding of complex subjects. In retail and e-commerce, these technologies are used to improve customer experience by allowing them to visualize products before purchasing.
✈️ Applications of Augmented and Virtual Reality (Part 2)
Further applications of AR and VR are discussed. In the travel and tourism industry, these technologies allow travelers to explore and experience places virtually before they visit. In manufacturing, AR and VR improve efficiency and productivity in factories. Lastly, the gaming and entertainment industry extensively uses these technologies to create immersive experiences, making AR and VR widespread in gaming environments.
🔚 Conclusion and Call to Action
In this final paragraph, the speaker wraps up the explanation of augmented and virtual reality, encouraging viewers to subscribe to the channel if they found the content informative. The video aims to clarify the distinctions between AR and VR and shows their wide range of applications in various industries.

hello my friends today i will explain
you
two latest trending technologies that
can change the way you look at the world
that is augmented reality and virtual
reality
the terms can be confusing sometimes
people think
argumental reality and virtual reality
are the same thing
today we will make it clear first let's
understand
what is augmented reality retailer ikea
created an application
that helps shoppers to visualize how
certain product will look like in their
home before they purchase them
the app overlays virtual version of the
product onto the real-life images of
customer living space
so customer can have a look how it is
suitable to their home
also you all are well known about
snapchat application
in snapchat you can add digital content
such as
additional noise ears text and 3d images
on your real-time images
these two are just example of ar
application we can say
in argument reality application a
digital layer is super embossed
on the real physical world and it mix
real world with virtual world to enhance
user experience
in short we can say that real world plus
virtual world is augmented reality
now let us discuss what is virtual
reality
just imagine if you want to feel like
you are walking on hillside
moon or you are seeming under sea using
vr applications
you can move to enter virtual world and
you can
feel like you exist in that virtual
world in short
we can define virtual reality is the use
of computer technology to create a
simulated environment
and make you feel like you exist in that
environment
it is done by simulating as many senses
as possible
such as vision hearing touch vibration
even smell
now let us see brief history of
augmented reality and virtual reality
in 1968 a harvard professor and computer
scientist mr
evan sutherland created first head
mounted display called
the sword of democracy with this device
a user
experienced computer generated graphics
that
enhanced their sensory perception of the
world
in 1990 a buying researcher mr
tom coddle first coined the term
argumental reality
now let us see brief history of virtual
reality in 1957
virtual reality was first achieved to
some extent by a cinematographer mr
morton helic he created a device
sensorama
it is a first virtual reality machine it
combined
multiple technologies to create all of
the sensors
there was combined full color 3d video
audio
vibrations smell an atmospheric effect
such as white
later in 1987 a computer scientist
researcher and artist
mr john lanier first time coined the
term
virtual reality now let us summarize the
difference between
argumental reality and virtual reality
in argumentative reality a digital layer
is superimposed on the real
physical world in virtual reality
computer technology is used to create a
simulated virtual world
in ar it is a mix of real world
and virtual world in vr it creates
entire virtual world in air a user can
clearly differentiate between real world
and virtual world
in vr for a user it is hard to
differentiate
what is real and what is virtual in air
user is not cut off from the real world
in vr
user is completely immersed in
artificial world
he is cut off from the real world in air
it only require ar compatible smart
devices such as
smartphone tablet laptop smart lenses
etc in vr it requires
head mounted devices or additional
equipments to get
fully immersed in virtual experience
these are the
basic difference between augmented
reality and virtual reality
finally let us discuss few application
of ar
and via first application is healthcare
industry
these two technologies are commonly used
in healthcare industry by doctors and
medical technicians
second application is military training
these technologies are
used for military training in virtual
environment
and creating virtual works third
application is
education augmented reality and virtual
reality is used for
education purpose it will give better
understanding for
students fourth application is a retail
and e-commerce industry
these two technologies are used in
e-commerce
and retail industry for enhancing
customer experience and visualizing
product before they purchase
fifth application is travel and tourism
travelers can
explore different places and details of
that places
using these two technologies even before
they travel
sixth application is manufacturing
industry
augmented reality and virtual reality
used in manufacturing industry for
increasing efficiency and productivity
of factories
seventh application is gaming and
entertainment industry
we all know that these two technologies
are nowadays
common in gaming and entertainment
industries
i hope that now augmented reality and
virtual reality
are very clear for you if you find this
video is
useful for you if you find this video
gave you some kind of information please
subscribe my channel
like and share thank you thank you very
much
