What is Augmented Reality?,How to make Augmented Reality application?,What are the various type of Augmented Reality?If you are finding the answer of these Questions then you are at the right place.
Before discussing the detail of AR(Augmented Reality) we would like to show a basic application of AR through our self-developed application,Below is the guide for using our Application.

Augmented Reality is the blend between the real world and the computer generated graphical world in real time through a digital interface which has a capturing (like-Camera,GPS..) and display mechanism(display,eye lense,projector..).A good AR application will blend the two world in an indifferentiable manner.See the application detail in Part 1.
MAIN COMPONENTS OF AR
There are three main components of AR-
1.
SCENE GENERATOR:The
scene generator is the device or software responsible for rendering
the scene. Rendering is not currently one of the major problems in
AR, because a few virtual objects need to be drawn, and they often do
not necessarily have to be realistically rendered in order to serve
the purposes of the application .
2.
TRACKING SYSTEM:The
tracking system is one of the most important problems on AR systems
mostly because of the registration problem. The objects in the
real and virtual worlds must be properly aligned with respect to each
other, or the illusion that the two worlds coexist will be
compromised. For the industry, many applications demand accurate
registration, specially on medical systems.
3.DISPLAY:The
technology for AR is still in development and solutions depend on
design decisions. Most of the Displays devices for AR are HMD (Head
Mounted Display), but other solutions can be found.
When
combining the real and virtual world two basic choices are available:
optical and video technology. Each of them has some tradeoffs
depending on factors like resolution, flexibility, field-of-view,
registration strategies, among others.
Display
technology continues to be a limiting factor in the development of
AR systems. There are still no see-through displays that have
sufficient brightness, resolution, field of view, and contrast to
seamlessly blend a wide range of real and virtual imagery.
THE BASIC IDEA
 |
| www.promethions.com |
The basic idea is to use the
camera of the android mobile through an application which has the
encoded information of the 3D object which the developer defined for
a target image in real world.
3.BLENDER
Blender is also very important software, it is used to design 3D model. This software is capable of designing the complex 3D model with minute specification. 3D model design in this software is used by the Unity for Augmented Reality and game development.
1.MARKERLESS: Markerless AR is that type of AR where no any activator is required from the real world,they mostly use the GPS of the device for placing the 3D objects. "Pokemon go" is the example of such kind of AR application.
FUTURE APPLICATIONS
SOFTWARE USED
As
one can see the core of this project is based on the softwares.
Following are the softwares and their functions which are used for
the development of basic application in Augmented Reality.
1.VUFORIA:
Vuforia
transforms the selected real world scene as a “Target Image” (As 100 rupee note in above case)and
rates the target image based on the unique features present in that
image on the scale of five on its own online portal. It also adds
the Augmented Reality feature in UNITY 3D(mentioned later).
2.UNITY-3D
This
is the heart of this project, essentially it is a game engine but in
our context it is used for:
- Incorporating the target image with the 3D model.
- Adding features to the models.
- Textures
- Rotation
- Audio
- Text
- Scripting etc.
- Multi-Platform Support: Applications built in Unity can be automatically transformed in several platforms without writing its code, such as for :
- Android
- ios
- Windows phone
- Web player
- Windows, Linux, Mac etc.
- Helps to develop UI.
Blender is also very important software, it is used to design 3D model. This software is capable of designing the complex 3D model with minute specification. 3D model design in this software is used by the Unity for Augmented Reality and game development.
TYPES OF AR
ON THE BASIS OF TARGET IMAGE:
1.MARKERLESS: Markerless AR is that type of AR where no any activator is required from the real world,they mostly use the GPS of the device for placing the 3D objects. "Pokemon go" is the example of such kind of AR application.
2.MARKERBASED:Markerbased AR is those AR where a scene from the real world is required for the activation,Like in the above mention application 100 rupee note was doing the work of activation of the model.
ON THE BASIS OF THE DISPLAY:
1.HEAD MOUNTED DISPLAY(HMD):
In this type of AR on see the real world through the camera not by the naked eye and processor mix the virtual scene with real scene.Its a Helmet kind of a device.
2.RETINAL:
We see the image when the light rays get reflected from the object and fall on the retina,what retinal AR does it create the light for virtual object which intersect on the retina.It can be used in the form Google glass(means spectacles) and Eye's lens as well.
3.MONITOR BASED:
Monitor based AR reaquire some display interface where the interfacing of the two world will appear it may be the smartphones,Monitor of the laptop and other thing.The important thing about these display device is they must have the camera.
4.PROJECTOR BASED:
Projector based AR formed the real 3D visual objects on a target with the help of projectors from different angle which intersect together to form the virtual visual 3D object.
FUTURE APPLICATIONS
- Archaeology: AR can be used to aid archaeological research, by augmenting archaeological features onto the modern landscape, enabling archaeologists to formulate conclusions about site placement and configuration.
Architecture: AR can aid in visualizing building projects. Computer-generated images of a structure can be superimposed into a real life local view of a property before the physical building is constructed there.
Wish:One of the interesting and innovative uses of Augmented Reality is related to greeting cards to wish the people.
Commerce: AR can enhance product previews such as allowing a customer to view what's inside a product's packaging without opening it.
Education: Augmented Reality applications can complement a standard curriculum. Text, graphics, video and audio can be superimposed into a student’s real time environment.
Gaming: Augmented Reality has huge potential in the gaming industry as it provides a very unique playing mechanism.
Medical: It has great role to play in the medical especially in the virtual 3d Anatomy is a great way to study the Body’s organ.
