For many of us, AR or VR or related technologies are abstractive or outlandish technologies with which we are still not familiar. These technologies we have only seen in sci-fi movies of Hollywood and are yet to experience in real life. But, the fact is that virtual 3D models, immersive displays with interactivity features, animated holograms etc. are not figments of imagination but things that do exist.


AR is a technological breakthrough which facilitates expansion of the physical word through addition of digital information layers over it. It is different from VR which creates the complete artificial ambience for replacing real world with a virtual replica. By inserting video, sound, multimedia elements, graphics etc. into the existing environment, AR leverages its views. The superimposition of CGI (Computer generated imagery) over the real world or physical environment’s view with the intent of modifying and enhancing the reality perception is called AR.


The term AR was phrased in 1990 and the technology was first used commercially for military and television shows. As smartphones and internet became more accessible, the next phase of AR was unveiled for offering heightened interactivity. Different augmented reality apps are being used for impacting our lifestyle, usage patterns, entertainment etc. wherein direct projection of 3D models on physical objects for their real-time fusion are changing our perceptions.


The digital animation is particularly connected by AR apps to a specialized ‘marker’. The GPS embedded in smartphones are also used for pinpointing specific locations. Augmentation takes place in real time in the context of the specific event being focused upon. While watching live cricket match, you must have observed scores or stats being overlaid on the ground. This is a typical example of AR.


Working of AR Technology

We are often interested in understanding about the technical aspect of the functioning of Augmented Reality. To enable AR features, data from pictures, videos, animations and 3D models is used. The results can be displayed in natural as well artificial perspectives. While viewing AR results, you would stay aware of the real-world features which is made possible by computer vision. This feature is missing in VR.


For displaying AR results, you can use glasses, handheld systems, smartphones, screens, head-gears or other suitable devices. Advanced technologies such as ‘simultaneous localization and mapping (S.L.A.M.)’ and depth tracking are used. For tracking depth, data from sensor is used to calculate the distance to the targets.


Other components are also used in AR. They include:

  • Cameras & sensors

    These are used for gathering information about interactions by users so that the same can be sent for processing. The surroundings are scanned by cameras mounted on devices. The info collected is used by AR devices for locating physical objects and generating 3D models. Images or videos can be captured using cameras that come installed in smartphones or special purpose cameras such as Microsoft Hololens.

  • Processors

    Augmented reality devices essentially function as small computers just like contemporary smartphones. Processors are used in them for measuring speed, orientation in particular direction, angle and other parameters. Processing is done using CPU, GPU, RAM, flash memory, GPS, Wi-Fi, Bluetooth and other elements.

  • Projectors

    AR headsets come installed with a small projector. It captures data from sensors for projecting digital content, which has been processed, on to the surface for viewing. Research work is still in progress in AR projection so that the same can be used economically in commercial projects.

  • Reflectors

    To facilitate proper viewing of the virtual images by human eyes, AR devices come installed with mirrors. Some devices have a number of miniature curved mirrors installed in them while others have double sided mirrors on them for reflecting light to the cameras and human eyes. The reflection paths are built for aligning the created images properly.

Different Augmented Reality Types

  • Marker Based

    This AR type is also known as image recognition based AR as specialized visual object is needed which would be scanned by a camera. The marker can be printed QR code, particular sign or anything. The marker’s location and orientation are also calculated by the AR device for positioning the content. This happens in certain cases. Digital animations are initiated by the marker for viewing by users. As such, magazine images may suddenly get transformed into 3D models when markers are triggered.

  • Markerless

    This AR type is also called position based or location based AR. Data about the location of user is provided by compass, accelerometer, GPS and gyroscope. The data is used for assessing the type of AR content available in a particular area. When viewed over the smartphone, this AR type usually generates maps, directions, info about businesses in the locality etc. Different applications consist of pop-ups about business ads, support for navigation, information about events etc.

  • Projection Based

    In this AR type, synthetic light is projected on to the physical surfaces. In certain cases, the light is allowed to interact with the surface. The AR effect is in the form of holograms which we have come across in Star Wars and other science fiction films. User interaction with the projection is detected by modifications in positions.

  • Superimposition Based

    Over here, the original view is replaced with complete or partial augmented reality. The concept revolves wholly around object recognition. In the IKEA catalog app, the model of superimposed AR is visible. Users are allowed to position virtual substitutes of furniture in the room within catalog.
