Augmented reality (AR) technology enhances real-world environments with digital overlays, allowing users to interact with 3D models, animations, and more through devices like smart glasses. There are several types of AR, including marker-based and projection-based, and its applications span various industries such as gaming, retail, manufacturing, and healthcare. The future of AR is promising with advancements in 5G technology and ongoing development of tools like Apple's ARKit, which continues to enhance user experiences through improved capabilities.

1. What is Augmented Reality
Technology
AR technology enables real-time augmentation that
takes place in the context of the surroundings. Users get
access to animations, photographs, movies, and 3D
models as well as the ability to observe objects in both
natural and artificial light.

2. Types of Augmented Reality
• Marker-less
• Marker-based
• Projection-based
• Superimposition-based AR
Augmented reality is of four types:

5. How Does AR
Work?
Augmented Reality aligns the real and
virtual worlds to create something
more immersive and powerful for
users. The most common forms of AR
involve adding data into a real-world
environment through the use of a
camera lens or a set of smart glasses.

6. Augmented Reality Application
Description
Application
Gaming
Retail and

Manufacturing and
Maintenance
Medicine/Healthcare
AR allows for better gaming experiences as gaming grounds are being moved
from virtual spheres to include real-life experiences where players can
perform real-life activities to play.
AR can improve customer experiences by presenting customers with 3D
models of products and helping them make better choices by giving them
virtual walkthroughs of products such as in a real estate.
In maintenance, repair technicians can be directed remotely by professionals to do
repairs and maintenance works while on the ground using AR apps without having the
professionals travel on the location. This can be useful in places where it is hard to
travel to the location.
AR can help train healthcare workers remotely, help in monitoring health
situations, and for diagnosing patients.

7. Future of Augmented Reality
• As apps and games like Pokémon Go and in-store AR apps become more well-known and popular, augmented
reality technology keeps expanding. By giving augmented reality applications faster data speeds and lower
latency, the development of 5G networks may make it simpler to enable cloud-based augmented reality
experiences.
• The open source mobile augmented reality development toolkit, ARkit, is still being developed and updated by
Apple. Target and Ikea are two businesses that employ ARKit in their leading augmented reality shopping apps
for the iPhone and iPad. With the help of ARKit 6, users may now capture and produce augmented reality (AR) in
4K HDR. In addition, ARKit 6 has a Depth API that uses per-pixel depth data to help a camera on a device
recognize the size and shape of an object. It also features scene geometry that generates a topological map of a
location and other improvements.
• ARKit's Android counterpart, AR Core, is also developing and getting better. For instance, AR Core employs a
geospatial API to access data from 3D models of Google Earth and Street View pictures.
• People who speak different languages will be able to communicate more effectively because to contemporary
innovations still under development, including Google's smart glasses that can translate speech to text in real
time. More opportunities and experiences across various platforms and media kinds are on the horizon thanks to
AR's usage of immersive technology.
