What is Augmented Reality (AR)

Augmented Reality brings the elements of virtual world into real word. Therefore it enhances user experience by enhancing the way we see, listen and feel. AR bridges the gap between real and virtual word. In AR computer generated images are superimposed on real word.

we suggest you to read article on Virtual Reality and Mixed Reality.

How Augmented Reality (AR) is Different from Virtual Reality (VR)

AR is completely different from VR. Virtual reality requires completely isolating users from real environment and brings them to simulated environments. This is achieved by wearing fully immersive VR devices.

Whereas augmented reality superimposes virtual information on top of real environment. As a result both real and virtual words co-exists. Therefore users get a completely different experience.

Types of Augmented Reality (AR)

Based on how AR is used, it classified in following types:

Marker Based Augmented Reality
Google Lens Working

To connect digital word with real word, visual marker is added in real word. Visual marker can be an image or QR code. For example, to display virtual information in a book. User point mobile camera to visual marker. Mobile application recognize visual marker and the animation can start immediately.

Similarly by scanning a product on mobile app, service engineer can receive product installation and maintenance guidelines.

Google lens is used for searches based on pictures. For example, Landmark, product or pet information can be searched using google lens Google will provide complete information about that product. 

Some of the examples of marker based AR applications are Popcode and Google lens.

Marker less/Superimposition based Augment Reality
IKEA Marketplace App Working

In this a user can move virtual objects in real word. For example, IKEA AR based mobile application is used to visualize virtual furniture inside your house. This allows IKEA customers to try different furniture at various locations. 

Snap chat Lenses, Filters and effects features are also based on marker-less AR.

Examples of marker-based augmented reality applications includes IKEA Market PlaceGoogle AR CoreSnap chat Lens Studio, Layar etc..

Examples of AR devices are Google Glass Enterprise Edition, Airplane pilot’s helmet etc.

Location-Based Augment Reality
Location/Position based AR uses GPS, digital compass and accelerometer to provide data based on user location. 
Google Maps AR Feature

It is most commonly for mapping direction finding nearby businesses tourist/ local guide, shopping centers and other location-centric mobile applications. 

Recently google has integrated augmented reality feature in their maps. This AR mode works  during walking navigation. You can markup building streets and get more details about them.

Some of the examples of location base augmented reality applications are google maps, AR pokemonAR City, Blippar Urban Visual Positioning etc.

Projection Based Augment Reality

Projection based augmented reality works by projecting light on real word surfaces and then sensing the human interaction such as touch by differentiating between expected and altered projection.

It is also used to simplify the complex manual tasks during product manufacturing and assembly. It replaces paper base work instructions by creating digital operating canvas on any work space. 

Interactive hologram is one of the example of projection based AR.

Applications of Augmented Reality

Augmented reality is not completely new term. It exists from a long time. It has applications from mobile games, education to manufacturing and design industry. 

  • Aviation Business
  • Communication
  • Construction
  • Product Design and Manufacturing
  • Education
  • Entertainment and Gaming
  • Healthcare
  • Shopping, Sports and Travel

Conclusion

To sum up, Augmented Reality brings the elements of virtual world into real word. It enhances user experience. AR has applications from education, design manufacturing to entertainment.
