AR (Augmented Reality)
Augmented Reality
A technology that overlays digital information onto real-world views
In Simple Terms
AR is a technology that overlays computer-generated digital information on top of what you perceive in the real world. Using a smartphone's camera, GPS, and other sensors, it identifies the user's location and what they're looking at, then displays characters, directional arrows, and more precisely aligned with the real scene. Beyond previewing how furniture would look in a room or displaying turn-by-turn arrows on real roads, AR is also widely used in professional settings — from assisting workers on factory floors to supporting surgeons during medical procedures.
Behind the Name
AR stands for Augmented Reality. 'Augmented' means increased or enhanced, and 'Reality' simply means the real world. It gets its name because the technology adds a layer of digital information on top of the real world — 'augmenting,' or expanding, what you see.
Take a Closer Look!
AR stands for Augmented Reality — a technology that overlays computer-generated digital information onto real-world sensory input (such as live video and audio captured from your surroundings). True to its name, it 'augments' the reality in front of you, making it more useful and engaging.
It works by first recognizing where the user is and what they're looking at, using a smartphone camera, GPS, or dedicated glasses-style devices. Based on that position and the captured image, it places characters, directional arrows, and other content precisely where they belong in the real scene.
Practical examples include apps that let you preview how furniture would look in your room before buying, and navigation apps that overlay turn-by-turn arrows directly onto real roads.
AR is also widely used in professional environments — from assisting workers on factory floors to supporting surgeons during medical procedures.
