What is Augmented Reality? How does AR work? Augmented Reality (AR)

 Augmented Reality as a demonstration of computer-generated digital characters or objects on a live view of the actual world

What is AR (Augmented Reality)?

We can define Augmented Reality as a demonstration of computer-generated virtual characters/objects on a live view of the real world.

⦁Augmented reality (AR) is a live view of a true real-world environment.

⦁The end-users view of reality is changed by digital sensory input such as voice, video or digital imagery.

⦁This tech is an instance of mediated fact. Mediated fact is a view of fact modified with the aid of using a computer.

⦁The technology works by changing someone’s perception of reality.

 Augmented Reality is about augmenting the real world environment with virtual information by improving people's senses and skills. There are 3 common characteristics of AR scenes: the combination of actual-world environment with computer characters, interactive scenes and scenes in 3D.

Augmented reality(AR) is the generation that expands our bodily world, including layers of virtual records onto it. Unlike Virtual Reality (VR), Augmented reality(AR) does now no longer create the entire synthetic environments to update actual with a digital one. AR seems in direct view of an current surroundings and provides sounds, videos, and photos to it.

A view of the bodily actual-international surroundings with superimposed computer-generated images, for this reason converting the belief of truth, is the Augmented Reality (AR ). 3-D fashions are without delay projected onto bodily matters or fused collectively in actual-time, diverse augmented truth apps effect our habits, social life, and the entertainment industry.

The truth is, we already know what Augmented Reality is, just might not know it is called the Augmented Reality. A more general and familiar example for augmented reality we all can understand is, the score board displayed on television screen when we watch sports and games. In cricket or football live telecasts, we can see the replay usually uses a graphical line that demonstrates the path of the ball. It is a composite view that is the combination of real world view and a virtual graphical line generated by a computer. It is known as Augmented Reality.

Mobile Augmented Reality 

Applications which use the mobile Augmented Reality usually take advantages of device's GPS and Compass features.Some of the popular mobile Augmented Reality applications generally use these techniques: They use the devices' GPS feature to find the location of the user, find information from the web and display theses information as texts/ images by integrating it to the live view of the real world using the device's camera and use the device's camera for image recognition and analysis, and embed virtual objects.

Desktop Augmented Reality

Desktop Augmented Reality usually takes advantage of a webcam to recognize the objects in the real world and embeds virtual objects to give a Augmented Reality experience to the user.

How does augmented reality work? 

Augmented reality works together with headsets and/or virtual gadgets which include tablets, clever telephones or even PCs. The gadgets themselves include software, sensors and virtual projectors that cause virtual presentations onto physical objects 

Augmented reality can be created and ate up in lots of extraordinary forms. For example, Google Glass shows 2D snap shots onto see-via glasses, at the same time as Microsoft’s HoloLens embeds 3-D snap shots into the sector round you. Apps together with Blippar, Zappar and Aurasma permit affordable (if now no longer free) AR content material advent for small businesses, training and lots greater industries, and of course AR features within existing smart phone apps and games.

For builders this system includes a tone of underlying algorithms, and once in a while the machine has to hit upon hundreds of various goal snap shots on the equal time, and which could purpose teething troubles withinside the software.

Some of you could already use AR for your day by day lives with out genuinely realising. Pokémon Go (despite the fact that the sport additionally is based closely on geolocation), Snapchat’s selfie filters and greater lately 3-D international lenses, and Facebook’s AR Studio for example, use simple AR to create face mask and animations prompted with the aid of using motion, gestures, facial expressions and person surroundings

Augmented Reality can be displayed on various devices such as screens, glasses, handheld devices, mobile phones, head-mounted displays

⦁ Cameras and sensors: Collecting information about user’s interactions and sending it for processing. Cameras on devices are scanning the surroundings and with this info, a device locates physical devices and generates 3-D models. It may be particular duty cameras, like in Microsoft Hololens, or now no longer unusualplace smart telecellsmartphone cameras to take pictures/videos.

⦁ Processing. AR devices in the end ought to act like little computers, a few element contemporary smart phones already do. In the same manner, they require a CPU, a GPU, flash memory, RAM, Bluetooth/Wi-Fi, a GPS, etc. in case you need to diploma speed, angle, direction, orientation in space, and so on.

⦁ Projection. This refers to a miniature projector on AR headsets, which takes information from sensors and projects digital content (cease end result of processing) onto a ground to view. In fact, the usage of projections in AR has now now no longer been simply invented however to use it in enterprise products or services.

⦁ Reflection. Some AR devices have mirrors to assist human eyes to view virtual images. Some have an “array of small curved mirrors” and some have a double-sided replicate to reflect slight to a virtual digital camera and to a user’s eye. The purpose of such reflected picture paths is to perform a proper image alignment.

Types of Augmented Reality:

⦁ Marker-based Augmented reality (AR)

⦁ Marker-less Augmented reality (AR)

⦁ Projection-based Augmented reality (AR)

⦁ Location based Augmented reality (AR)

⦁ Superimposition based Augmented reality (AR)

Marker-based Augmented reality (AR)

Marker-primarily based totally ARMarker-primarily based totally AR, because the call suggests, makes use of a visible marker, generally withinside the shape of a 2D QR code to cause augmented truth experience. This is made feasible via marker-primarily based totally programs that use the digital digicam at the tool to understand the code and convey AR consequences on pinnacle of it.

Some additionally name it to photo recognition, because it calls for a unique visible item and a digital digicam to experiment it. It can be anything, from a broadcast QR code to big signs. The AR tool additionally calculates the location and orientation of a marker to place the content, in a few cases. Thus, a marker initiates virtual animations for customers to view, and so pics in a mag might also additionally grow to be 3-D models.

Marker-less Augmented reality (AR)

Markerless AR does now no longer require photo reputation to cause augmented experiences. Instead, the AR content material receives displayed via positional records amassed from the device's camera, GPS, virtual compass, and accelerometer. The inputs from those records factors permit the device to apprehend the three-D surroundings via a procedure called Simultaneous Localization and Mapping (SLAM).With the provision of clever telephones this form of AR normally produces maps and directions, close by groups info. Applications consist of activities and records, enterprise advertisements pop-ups, navigation support.There are wonderful versions of Markerless AR - projection-primarily based totally and region-primarily based totally

Projection-based Augmented reality (AR)

Project-primarily based totally augmented truth includes projecting immersive mild paperwork onto flat surfaces after which sensing the human interplay with that projected mild. Projecting artificial mild to bodily surfaces and in a few instances lets in interacting with it. These are the holograms we've all visible in sci-fi films like Star Wars. It detects consumer interplay with a projection with the aid of using its alterations.

Location based Augmented reality (AR)

Location primarily based totally AR is taking benefit of the clever devices’ region detection features. If you’re a visitor and also you need to find out new first-rate places, this approach will use your region with the aid of using studying your clever device’s GPS, compass and accelerometer and come up with applicable records approximately what you’re seeking out to your screen

Superimposition based Augmented reality (AR)

Superimposition primarily based totally AR additionally makes use of item popularity with a view to update a whole item or part of it with an augmented view. For example, if you’ve ever performed FPS games, you know the way your soldier may also have superior army gadget displaying infrared view, night time vision, radioactive view, etc. – that is all superimposition primarily based totally AR. Also, in medicine, a medical doctor can use this era to superimpose an X-ray view of a patient’s damaged arm bone on a actual picture to offer a clean knowledge of what the bone’s harm virtually is
