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.
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
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.
Marker less/Superimposition based Augment Reality
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 AR devices are Google Glass Enterprise Edition, Airplane pilot’s helmet etc.
Location-Based Augment Reality
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.
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
- Product Design and Manufacturing
- Entertainment and Gaming
- Shopping, Sports and Travel
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.
