Augmented reality (AR) merges the physical world with the virtual world. This is just as fascinating as it is technically complex – especially with AR glasses, which are coming into fashion.  

These Smart Glasses are a new generation of wearable devices, and prominent examples include Microsoft Hololens or Google Glass. Smart Glasses combine (and blends) the virtual world with the physical world.

These glasses are typically a new form of media devices. They are more than just wearables or a new generation of smartphones. They are not just “EyePhones”. Smart glasses are the future of media technology

But the real question now is… How Do AR Glasses Work?

Here we will take a full review of how Augmented reality glasses really work in 2020.

Uses of Augmented Reality In Real World

Here is a simple real-world scenario of using Augmented Reality: A user captures the image of a real-world object, and the underlying platform detects a marker.

This marker then triggers it to add a virtual object on top of the real-world image and displays on your camera screen.

Here are some Real-World Examples of AR uses:

  1. AR applications can become the backbone of the education industry. Apps are being developed which embed text, images, and videos, as well as real-world curriculums.
  2. Printing and advertising industries are developing apps to display digital content on top of real-world magazines.
  3. With the help of AR, travelers can access real-time information of historical places just by pointing their camera viewfinder to subjects.
  4. AR is helpful in the development of translation apps that can interpret the text in other languages for you.
  5. Location-based AR apps are major forms of AR apps. Users can access information about the nearest places relative to the current location. They can get information about places and choose based on user reviews.

With these uses of augmented reality in mind, let’s define AR glasses and how they fit into this mould. Shall we?

What are Augmented Reality (AR) Glasses?

Augmented Reality (AR) devices that are worn like regular glasses that can merge virtual information with physical information.

When wearing such glasses, users can see their physical environment in the same way as regular glasses.

However, AR smart glasses like Google Glass superimpose additional content to whatever users see.

How Does Augmented Reality Glasses Really Work?

In reality, the magic of augmented reality glasses is nothing more than science and the clever use of our mind’s ability to interpret images and allow itself to be tricked by visual stimuli. This model works the same for our augmented reality glasses at Ingres Quality Rollout.

AR glasses are a combination of a few key components which work together to create the effect of extra items added to the real world.

Let us take a look at these components:

#1 The Display

The combiner is the display of AR glasses. It combines glass lenses that allow natural light to pass on through to the eyes with digital LED or OLED displays which send the computer-generated images to the eyes.

Hence, when one wears an AR glass, they see images from a double source: the real world outside and the computer-generated objects.

#2 The Camera

The AR mobile or web app cannot exactly see through your eyes. So, it needs a camera to record the images in the real world. This camera is attached to the AR glasses or, if you are using a smartphone, the phone camera is activated to capture images.


#3 The Registration

The registration consists of icons (which the wearer cannot see) through which the computerized part of the devices places an AR object in the real world. These icons or markers are the reason why you suddenly see a new sofa or a coffee table in your room when you are trying a home décor augmented reality app.

The icons or markers use various landmarks from the real world image for guidance, such as the corner made between two walls, the lines of the window, the geometrical shape of a carpet, etc.

This is what makes it possible to train offshore workers remotely in the oil and gas industry using our Over-The-Shoulder coaching solution.

#4 The Computer Vision

At this junction is where “the magic” happens. Here, a programmed app or software suite has to combine the two types of images – the one supplied by the camera and the one generated by the registration with the aid of the markers.

The result of this combination is what you actually see through the augmented reality glasses that appear real.

#5 The Field of View

A very important factor to consider when shopping for AR glasses is field of view. This makes the difference between truly immersive experience and looking at something through swimming goggles. The usual human field of view is around 210 degrees horizontally and 150 degrees vertically.

Also, AR glasses cannot reproduce these numbers, first of all, due to the physical limitations of placing the lenses in a headset.

So, there is the issue of the computing power needed to process and display the digital objects with reasonably high fidelity and resolution. At present, a 50-degree field of view is already large for augmented reality glasses.


 AR glasses are a combination of a few key components which work together to create the effect of extra items added to the real world. This innovation has made it possible to handle remote training hence reducing the cost of teaching across all industries.
