welcome to the age of new realities

virtual and augmented the world is

advancing faster than it has ever before

it is hard to keep up with the

day-to-day technological advancement so

at any given time there is a plethora of

new technologies to keep your eye on

especially if you're an investor is the

investors job to know the next big thing

and one of the things that the investors

are heavily investing is in virtual and

augmented reality we are surely spending

most of our time looking at screens

beaten laptop TV or a cell phone they

have become a big part of our lives and

VR and AR are the two technologies that

are changing the way we use screens

creating new and exciting experiences

both in a different way the market for

AR and VR products in 2018 is expected

to be seventeen point eight billion

dollars but by 2022 it is expected to go

as high as two 150 billion dollars now

that's a lot of dollars to think about

especially when we had just four years

away from 2022 now AR and we are both

are two different things and each has

its strengths and weaknesses so let's

start with via emerging yourself into an

totally different world that is the

virtual world is the whole concept of

the VR technology the use of computer

technology to create simulated

environment of which we become a part

and can live that experience the

sensorama was a machine that is one of

the earliest known example of immersive

multi-sensory technology which could be

considered as some sort of virtual

reality thing it had screens you could

have smells you can experience the wind

blowing through your hair and much more

now I when Edward Sutherland is an

American computer scientist and internet

pioneer widely regarded as the father of

computer graphics now the soir of

damocles is widely considered to be the

fourth virtual reality head-mounted

display which is the hmd system it was

created in 1968 by Ivan Sutherland

with the help of a student Bob sprout

before he began working towards what he

termed the ultimate display now virtual

reality uses head technology who every

move our head to look around what's

happening although we are made a lot of

promises back in the late 80s and 90s it

did not evolve much apart from gaming

and arcades Sega introduced the concept

of VR headset in the market but it was

actually a Nintendo which released the

infamous Virtual Boy now when I say

infamous

I'll explain why it was such a huge

disaster the display was only 244 pixel

wide and there was only a single color

used that is red moerewa it was

uncomfortable and expensive for an

average gamer to buy that headset there

was a lot of hype in the 90s but the

technology wasn't right and ready to

deliver that hype today we have the

right technology where we can create

high-definition 3d content and create

immersive experience that are very close

to real life although it mostly used for

gaming it was supposed to give us an

experience of travel with our traveling

and experience Intel in new words it is

now being used in research and therapy

too which is also used for people having

acrophobia which is the phobia of height

how is your anxiety now I still feel

okay quite high up to be this close to

the edge with very little barrier ok

nowadays VR content is useful for PTSD

and cognitive therapy patient surgeons

are using VR to practice highly

technical surgeries before operating and

businesses are using them to give a

virtual tour now talking about the types

of VR tech available right now we have

wired and wireless now wired are the

ones which are connected to a good

processor and usually work a lot faster

and smoother but the thing about the

wired we are at cert is that first of

all they are expensive and secondly the

movement is limited at the headset is

connected to a system or a processor

which is doing the heavy computing now

when it comes to wireless we use the

mobile phones and talk them into the VR

headset although the mobile screens do

not provide a very high definition and

the fast processing content as the

screen size is small it provides you

with the ability to move as it as well

as you can carry 8

anywhere and it does not very much so

the famous example of the via headset is

the oculus rift

we have HTC vive and we also have the PS

we are in the wireless category we have

Samsung gear we are and the Google Data

in view on one hand where we are takes

you to only the world they are at thanks

to the existing world the word argument

has derived from the latin word our grid

which means to add or increase it does

not cut out the real world but rather

it's an enhancement of the real world

where we mix the real world with virtual

objects and that creates beauty that's

why it is sometimes referred to as mixed

reality now when a person's real

environment is supplemented or augmented

with the computer-generated virtual

images it is known as augmented reality

magically was one of the first company

to introduce air to the wall it's

secured around 15 million dollar

investment in 2014 and released the most

famous magically one recently who will

invested 2.3 billion dollars to this

company you can think of it as the

oculus rift of air technology they have

been making great advancement in content

usage and the high-definition wide-angle

view there is also the concept of smart

lenses it is similar to a lens but helps

in creating content and that too without

using any external devices but just your

eye with AR you can interact with stuff

right in front of you as if it was an

object in the room you kind of

manipulate it and it completely creates

a new environment around you you might

have heard about the wisely famous

Pokemon go I know you have now more than

three hundred and eighty million users

were playing it at one single point that

has one out of every 20 people on the

earth now if you've used snapchat then

you are already using air there various

phase filter are all AR based what

snapchat does is that it presents a

layer of reality over the reality in

which we are already in now AI users can

interact with the virtual content in the

real world and can distinguish between

the two if we look at the usage of the

er technology apart from gaming if

implemented right business can use it

correctly to work customers through the

repairs

or efficiently the best suited example

for this one is the Volkswagen Mota it

is an app which provides the real-time

augmented reality implementation of how

to repair your car other examples

include the Google Translate then again

we have the Google glass and we have the

most famous hololens by Microsoft now it

was Microsoft who first coined the term

mixed reality not talking about the

different types of realities AR and VR

they had two different things and each

has its own strengths and weaknesses in

the long run

here is gonna be the winner now that's

what I think because the future is

molted it was AR because if you look at

what's happened with our cell phones

over the last 10 years they have become

more and more an extension for ourselves

into the lives and the world we have

been augmenting reality with our phone

this whole time it's it's sort of an

extension to what we are already doing

with our cell phones it allows you to

interact with the real world and still

add virtual things to the environment if

we look at the different VR gears

only a few people have it so it's

widespread adoption rate is much lower

as compared to the air technology and

where the only thing you need is a

smartphone or a tablet now this doesn't

mean that we are does not have as place

they can be many wonderful application

of virtual reality not just in gaming

but also in therapy there are even

studies where people with paralyzed

limbs and people in shock have learned

to walk again which helped them to

visualize their feet stepping one in

front of the other it helps them to

recreate it in the real life now one

thing I do want to say here is that in

the future there might be a scenario

where we have VR and they are in the

same device and you can switch between

the two seamlessly one moment you are

walking in your office and doing other

work when suddenly you feel tired and

want to sister VR I have a smooth and

relaxing experience I believe that the

gap between these two are going to end

very soon and that too in the side of

air but who knows if we might develop

some dope technology where we have such

high definition graphics that it looks

almost like reality and we are then

takes on air who knows

let us know in the comments below what

you think is the future

I hope you have enjoyed listening to

this video please be kind enough to like

it and you can comment any of your

doubts and queries and we will reply

them at the earliest do look out for
