Hello and welcome to this and you will listen in on Chad going to talk about types of augmented reality.
The first time is Margolis a half or Mark less augmented reality.
The second time is marker based augmented reality.
The third type is projection based augmented reality and the fourth type is somewhat in position based
augmented reality.
Now we are going to explain each of them with an example
as you can see in this image we have the marker based A.R. Some also call it to image recognition as
it requires a special visual object and a camera to scan it and to be able to view it may be anything
from a printed QR code to special signs they are device also calculates the position and orientation
of a marker to position the content in some cases thus a marker initiates digital animations for users
to view and so images in a magazine may be or may turn into a 3D model as you can see in this image.
This is the marker based they.
This is the mark.
And this is our mobile device using its camera.
We are going to capture the mark and capture its orientation the angle and everything.
And we can view anything on this Mark.
Now again if you did rotate around the table you can see different views of the house.
You can see the front view the top view the bottom view on the right and left view.
It's very hands full when you are viewing 3D objects and 3D models.
I'm going to show you this type of a are in the practical section of this course.
So stay tuned.
We usually do the practical thing at the second half of our courses.
Now let's talk about the second type of air.
Now the second time is Mark loyalists or Mark Atlas A R.
It's also called location based or position based augmented reality.
It's the type that utilized a GP as a compass as it is called and an accidental meetup to provide that
are based on user's location this debt then determines what they are content to find or get in a certain
area with the availability of smart phones.
This type of a r typically produces maps and directions nearby business information.
Applications include events and informations.
You can also view business ads pop ups and navigation supports just like the ones you find in Google
Maps app the same concept was also used in the very popular game which is called Pokemon goal.
You can look it up online to see how this marvelous A R was implemented.
As you can see once you hold a device in that place and a certain place you in a certain G.P.S. coordinates
it will show you information about that device.
In this area as you can see in this image now the third type is called projection based.
A R projection synthetics lie to physical surfaces and in some cases allows to interact with it.
These are the holograms we have all seen in sci fi movies like Star Wars.
It detects user interaction with a projection by its alternation.
As you can see there is no physical shoes in this state or on this table.
This is our projection of a 3D scan or a 3D let's say design of our shoes a company can use this to
view or to show others their prototype or their products so that people can check the details of their
product and sometimes they allow people to interact with them.
So you can move it around with your hand depending on the type of technology used.
It's very pleasant to see and it looks really like a sci fi movie and this time needs a projector to
project the image usually a 3D projector.
Now we come to the fourth type which is super imposition based in art.
It replaces the original view with an augmented fully or partial view object recognition plays a key
role without it.
The whole concept is simply impossible.
We have all seen the example of soba imposed augmented reality in Ikea catalog app.
This app allows users to place virtual items of their furniture catalog in their rooms before buying
them.
So if you have a small room you can go and download IKEA catalog app.
I will show you this in the practical section and you can see how you can easily place your furniture
around to see if it fits in your room or not.
Before buying it.
And this saves a lot of money and help people choose what fit for them without having to buy items place
them and find out later that the place doesn't fit these items and that they have to go back and replace
it with another one.
Ikea was the leader of this support and position based a R and it was a great step from them to use
a r to make people's life easier.
These are the four types of augmented reality.
Next we are going to discuss the merge cube which we are going to apply in this course so that you can
create your own augmented reality experience in your home.
Thanks for watching this lesson.
