Augmented Reality in ARKit Development

While studying ARKit, you need to know what augmented reality is. This chapter covers the Idea of Augmented reality, and the types and differences between AR (Augmented reality), VR (Virtual reality), and MR (Mixed reality).

What is Augmented Reality?

Augmented reality is the real-time integration of digital information such as 3D graphics, audio, and other sensory inputs into the user’s environment.

The following are the key features of augmented reality −

• Integration of the digital and physical world − AR enhances the user’s experience by integrating digital elements such as images, sounds, and other data into the physical world.
• Real-Time Interaction − Users can interact with digital content in real-time.
• 3D Registration − AR devices can accurately overlay digital information into the real world. This means virtual objects that appeared are at the right spot and scaled correctly relative to the real world

Types of Augmented Reality

The following are the different types of Augmented reality −

• Marker-based AR − Marker-based augmented reality uses QR codes to create 3D experiences on mobile devices. Users need specific apps and it can be used with mobile devices only. It is also called a fiducial marker.
• Markerless AR − Markerless Augmented reality uses GPS and sensors to place virtual objects in the real world without needing QR codes. It lets users see digital items on surfaces like floors or walls, making it popular for online shopping and gaming. It is more complex and costly to set up.
• Projection-based AR − Projection-based Augmented reality uses projectors to display 3D images on flat surfaces like walls or floors.
• Superimposition-based AR − Superimposition-based augmented reality enhances by replacing real-world views with digital elements. For example, with the help of superimposition-based AR, we can show directions or display product details.
• Location-based AR − Location-based AR uses GPS to show digital content at specific places, like in games such as Pokémon Go. Brands can use it for fun shopping experiences, like virtual scavenger hunts.
