What is Augmented reality? How does it work?

Augmented reality interest is increasing as the innovators explore the business importance. AR plays a vital role in workforce enablement and client experience and cooperation.This rising innovation holds huge guarantee for changing the manner in which organizations work. Let us see the details of Augmented Reality.

What is Augmented Reality?

Enlarged the truth is the innovation that grows our physical world, including layers of digital data onto it. In contrast to Virtual Reality (VR), AR does not make the entire artificial intelligence to replace with a virtual one. AR shows up in direct perspective on a current situation and includes sounds, videos, graphics to it. A view of the physical real-world environment with superimposed computer-generated images, consequently changing the view of the truth, is the AR. With the increase in the use of the internet and smartphones, AR revealed its subsequent wave and these days is mostly related to the interactive concept. 3D models are legitimately projected onto physical things or melded progressively, different expanded reality applications impact on our habits, social life and the entertainment industry.

AR applications commonly connect digital animation to an extraordinary ‘marker’, or with the help of GPS in telephones pinpoint the area.

There are 4 types of augmented reality:

1. markerless AR
2. marker-based AR
3. projection-based AR
4. superimposition-based AR

How does Augmented Reality work?

AR can be shown on different gadgets: screens, glasses, handheld gadgets, cell phones, head-mounted showcases. It includes innovations like S.L.A.M. (simultaneous localization and mapping), depth tracking (briefly, a sensor data calculating the distance to the objects), and the accompanying parts:

1. Cameras and sensors-

Cameras on devices are for scanning the surroundings. With this info, a device locates physical objects and generates 3D models. It might be a special cameras, like Microsoft Hololens, or common smartphone cameras to take pictures/videos.

2. Processing-

AR devices eventually should act like little computers, something modern smartphones already do. In a similar way, they require a CPU, a GPU, flash memory, RAM, Bluetooth/WiFi, GPS, etc. so on to have the option to measure speed, angle, direction, orientation in space, etc.

3. Projection-

This refers to a smaller projector on AR headsets. These headsets takes data from sensors and projects digital content (result of processing) onto a surface to see. In fact, the utilization of projections in AR has not been fully invented yet to use it in commercial products or services.

4. Reflection-

Some AR devices have mirrors to help human eyes to view virtual images. Some have an “array of small curved mirrors” and some have a double-sided mirror to reflect light to a camera and to a user’s eye. The goal of such reflection paths is to perform a proper image alignment.

Types of Augmented Reality-

1. Marker-based AR-

It is also called as image recognition,because it requires a special visual object and a camera to scan it. It may be anything, from a printed QR code to special signs. The AR device calculates the position and orientation of a marker to position the content, in some cases. In this manner, a marker starts advanced activities for clients to see, thus pictures in a magazine may transform into 3D models.

2. Markerless AR-

It is also known as a location based or position based augmented reality, that uses a GPS, a compass, gyroscope and an accelerometer to provide data according to user’s location. This information at that point figures out what AR content you find or get in a specific zone. With the accessibility of cell phones this sort of AR regularly delivers maps and directions, close by organizations data. Applications incorporate events and information, business ads pop-ups, navigation support.

3. Projection-based AR-

Projecting synthetic light to physical surfaces, and in some cases allows to interact with it. It detects user interaction with a projection by its alterations.

4. Superimposition-based AR-

Replaces the original view with an augmented, fully or partially. Object recognition plays an important role. Without it the whole concept is simply impossible. 

Augmented Reality devices-

1. Mobile devices–

AR in Gaming

The most available and best fit for AR mobile apps, ranging from pure gaming and entertainment to business analytics, sports, and social networking.

2. Special AR devices–

These devices are designed primarily and entirely for augmented reality experiences. One example is head-up displays (HUD), sending data to a transparent display directly into user’s view. Originally introduced to train military fighters pilots, now such devices have applications in aviation, automotive industry, manufacturing, sports, etc.

3. AR glasses-

AR Glasses

It includes Google Glasses, Meta 2 Glasses, Laster See-Thru, Laforge AR eyewear, etc. These are able to display notifications from your smartphone, assisting assembly line workers, access content hands- free, etc.

What’s the difference between Augmented Reality and Virtual Reality?

Augmented Reality (AR)- It improves, enhances or expands real life by inserting virtual objects into the user’s real world environment. Virtual Reality (VR) creates a completely virtual world that users interact with using devices that isolate the user from the real world. VR grabs headlines, but researchers say AR will prove to be a bigger market after some time.
