Augmented reality (AR) is a technology that enables users to interact with virtual objects and data in the real world. It has the potential to change different areas of our life, including how we work and study as well as how we play and shop.

In this blog article, we'll explore the various forms of augmented reality (AR) and the industries and applications in which they are employed.

Essentially, there are two main categories of Augmented Reality: Marker-based AR and Markerless AR.

Marker-based AR

This type of AR uses visual markers, such as QR codes or special images, to trigger the display of virtual content. The camera is made scan the input and recognize image patterns in order to create the geometry of the virtual objects.

When the user points their device at the marker, the AR technology recognizes it and displays the corresponding virtual content. This kind of augmented reality is often easy and affordable to create.

Marker-based AR is commonly used in marketing and advertising, where it can be used to provide customers with more information about a product or service. A customer could point their device at a product in a store, and the AR technology would display additional information, such as product specifications or customer reviews.

Markerless AR

Markerless AR allows virtual 3D objects to be positioned in the real image environment by examining the features present in the data in real time. This type of AR is more versatile than marker-based AR, due to the advancements in cameras, sensors, and AI algorithms.

Simultaneous localization and mapping (SLAM) is used in markerless AR to scan the surroundings and provide suitable maps for the placement of virtual objects.

Location-based AR, Projection-based AR, Overlay AR, and Contour-based AR falls under this category.

  • Location-based AR: This type of AR uses GPS technology and other sensors to trigger the display of virtual content based on the user's location. For example, a user could walk down a street and see virtual data overlaid on the buildings and landmarks around them. Location-based AR is commonly used in tourism and navigation applications, where it can provide users with more information about their surroundings.

  • Projection-based AR: This type of AR uses projection mapping to create the illusion of virtual objects being present in the real world, that can be seen and interacted with. For instance, a user could use a projector to create a virtual chessboard on a table, and then use their hands to move the virtual pieces. Projection-based AR is commonly used in entertainment and gaming applications, where it can create unique and immersive experiences for users. It can also be used in education and training, where it can provide a more interactive and engaging way to learn.

  • Overlay AR: Also known as "Superimposition AR" involves replacing the original view of a real world object with an augmented or alternate virtual display which can often be customized with multiple visual perspectives. Overlay AR provides a user, multiple views of a target object with the option of highlighting extra relevant information on that object in real-time.

  • Contour-based AR: This type of AR works by basically outlining the  of objects and simulate a realistic human interaction. For example, it might be used to develop a safe-driving application for nighttime, poorly-lit roads, heavy precipitation, and other low-visibility situations.
