Augmented reality (AR) is a real-world interaction experience in which real-life objects are developed by computer-assisted mind. AR can be described as a system that fulfils three basic elements: a combination of real-world and virtual world, real-time communication, and precise 3D registration of virtual and virtual reality. Neglected sensory details can be positive or negative. This experience is so seamlessly integrated into the physical world that it is considered a diving element of real nature. In this way, augmented reality alters one’s ongoing perception of a real-world environment.
Types of Augmented Reality (AR)
Projection based AR-
As the name implies, this type of AR projects digital images into objects in the physical space. It could be a collaboration and project on a digital keyboard on your desk, or a dialler in your hand. It might be non-interactive and may be used to create speculations about what you can store and see in depth – for example, it may indicate that your future refrigerator will fit into the space you have near the oven by installing a refrigerator in front of you.
Whenever you scan a QR code, or scan an image and reside (like iGreet cards) you are actually using visual-based AR. This is how iGreet works – the AR app detects and detects something called the AR marker. When you see a marker, you replace it with something that matches. Another type of AR-based technology is the one that translates words seen with the camera. This type of AR also looks like the most widely used – along with the next one.
Location based AR-
Local-based AR takes advantage of the location detection features of smart devices. If you are a traveller and want to discover new beautiful places, this method will use your location by learning the GPS, compass and accelerometer of your smart device and give you the right information about what you want on your screen.
Outlining based AR-
The line here is a slight blur – which describes AR using object recognition function, and may appear similar to projection based AR. For example, whenever you park your modern car in the dark, it means the AR recognizes road boundaries and sets you up. This method can also be used in architecture and engineering to describe buildings and their supporting pillars.
Superimposition based AR-
Superimposition based AR also uses object recognition to insert an object or part of it into an augmented view. For example, if you have ever played FPS games, you know how your soldier can have advanced military equipment featuring infrared viewing, night vision, radiation viewing, etc. Also, medically, a physician can use this technology to elevate the X-ray view of a patient’s broken arm bone in the actual image to give a clearer understanding of what bone actually is.
True future of AR-
With AR’s market value rising to $ 25 billion by 2025, the true future of potential owners is bright. This growth will only continue in the coming years, which is determined by investment from business and sector domains in the following chart:
