What is Augmented Reality?


Augmented reality (AR) is a technology that overlays digital information, such as text, images, or 3D models, onto the real-world environment. Unlike virtual reality (VR), which creates a fully immersive digital world, AR enhances the user's perception of the physical surroundings by integrating virtual elements into their view of reality.

AR works by using a device's camera to capture the real-world environment and then superimposing digital content onto that view, creating a composite image that combines the physical and virtual worlds. This digital overlay can be triggered by various means, such as visual markers, GPS coordinates, or object recognition algorithms.

The key difference between AR and VR lies in their approach to blending digital and physical worlds. VR completely replaces the user's surroundings with a simulated environment, while AR adds digital elements to the existing environment, allowing users to interact with both virtual and real-world objects simultaneously.
