What is Augmented Reality (AR), Types and Applications of AR.

Augmented Reality (AR) is a real-world environment's interactive experience where the items that live in reality are improved by PC produced perceptual data, sometimes across various tactile modalities, including visual, sound-related, haptic and olfactory. AR is quickly developing in notoriety since it brings components of the virtual world, into our real world.

The origin of the word 'augmented' is augment, which intends to improve or include something. On account of Augmented Reality, sounds, designs, and touch feedback are added into our regular world to make an improved client experience

Augmented Reality utilizes your current common habitat and simply overlays virtual data on its highest point. As both virtual and real world agreeably exist together, clients of AR experience a better than ever normal reality where virtual information is utilized as an instrument to give help with everyday exercises.

The first AR technology was created in 1968 at Harvard when PC researcher Ivan Sutherland created an AR head-mounted display system. The term Augmented Reality(AR) was coined by Boeing analyst Tom Caudell in 1990. In 1992 AR was first utilized for navigation, in NASA's X-38 shuttle. AR applications for cell phones regularly incorporate Global Positioning system (GPS) to pinpoint the user's area and its compass to identify gadget direction.

Augmented Reality apps are written in 3D programs that enable the engineer to tie liveliness or logical computerized data in the PC program to an Augmented reality in real world. At the point when a registering gadget's AR application or browser plug-in receives advanced data from a known marker, it starts to execute the marker's code and layer the right picture or pictures.

The distinction between Virtual Reality and Augmented Reality:

In Virtual Reality (VR), the user's view of the reality is totally based on virtual data. In Augmented Reality (AR) the user is furnished with extra PC produced data that improves their impression of the real world. For example, in engineering, VR can be utilized to make a walk-through simulation of within another structure; and AR can be utilized to demonstrate a building's structures and frameworks super-forced on a genuine( real-life) view.

There are 4 main types of AR(Augmented Reality):

1. Marker based Augmented Reality (also called Image Recognition).
   Marker-based AR (also known as Image Recognition) utilizes a camera and some sort of visual marker, for example, a QR/2D code, to deliver an outcome just when the marker is detected by a reader. Marker put together applications utilize a camera with respect to the gadget to recognize a marker from some other genuine item.
2. Marker-less Augmented Reality (also called location-based, position-based, or GPS).
   Marker-less AR (also known as area based, position-based, or GPS) utilizes a GPS, velocity meter, digital compass, or accelerometer which is installed in the gadget to give information dependent on your area.
3. Projection Augmented Reality.
   Projection based AR works by anticipating counterfeit light onto genuine(real world) surfaces.
4. Superimposition Augmented Reality.
   Superimposition based AR either partially or completely replaces the original perspective on an item with a new augmented perspective on that same article. In this type of augmented reality, object recognition plays an essential job in light because the application cannot replace the original view with an augmented one if it cannot find what the object is.

Applications of AR (Augmented Reality).
