Augmented Reality: How Does It Work?

Augmented Reality (AR) blends digital content with the real world through smartphones, tablets, and AR wearables. It’s transforming entire industries, redefining digital experiences, and driving growth in the global economy. But how exactly does AR work? And can it be applied to your project? Let’s first take a closer look at what “augmented reality” truly means.

What Is Augmented Reality?

The working principle of Augmented Reality is based on the real-time integration of digital information into the user’s environment. AR enriches a user’s perception of reality without replacing it with a simulation. This technology relies on smartphones and tablets, equipped with cameras, sensors, and displays, as well as wearables like smart glasses and headsets. AR has achieved significant adoption across both business and consumer sectors. Popular examples such as Pokémon GO, IKEA Place, and Google Lens showcase the power and versatility of AR.

How Does Augmented Reality Work?

AR works through the built-in camera on your smartphone or tablet. Here’s a step-by-step breakdown of how the AR process works:

• Data capture: The AR device records video from the user’s field of view, detecting and tracking physical objects within the environment.
• Environment understanding: Technologies like tracking and SLAM (Simultaneous Localization and Mapping) gather data from accelerometers, gyroscopes, and GPS to determine the user’s position and movement.
• Rendering digital content: The AR software processes this data and streams digital elements into the user’s view.
• Displaying the augmented view: Digital content is rendered with accurate perspective and orientation, appearing to the user as if the object were physically present. Users can interact with these digital elements, often through a touchscreen or gesture controls.

While traditional AR setups often require complex hardware or app installation, Vizbl eliminates these barriers. Our platform automatically handles data capture, spatial mapping, and rendering through the browser, so companies can launch AR experiences without coding or custom development.

Working Principle of Augmented Reality

AR integrates specialized hardware and software to overlay digital information onto the physical environment. Core technologies such as cameras, sensors, and trackers gather data from the surroundings. The AR software then processes this data to generate precise 3D content. Devices like smartphones, AR glasses, and headsets enable users to interact with digital elements, including 3D models, images, and videos. The synchronization between hardware and software ensures smooth and realistic performance of these virtual elements.

Key Technologies That Power AR

The working principle of augmented reality relies on a combination of hardware and software that creates an immersive and interactive experience. Key components of this technology include:

• Cameras and sensors: AR devices use cameras and various sensors to capture real-world environments. The data collected from these inputs is essential for overlaying digital elements onto the physical space.
• Processors: AR processors analyze the real-world data collected by cameras and sensors in real time. They recognize objects, track movement, and render 3D models.
• AR software/SDKs: AR technology is based on computer vision algorithms that process visual data to recognize and interpret real-world objects.
• SLAM and spatial mapping: AR systems use SLAM to create a virtual map of the environment while continuously tracking the device’s position. This ensures digital overlays remain stable and aligned as the user moves.‍
• Display systems: A smartphone screen or transparent lenses in AR glasses let users see the augmented content overlaid onto their view in real time.

Types of Augmented Reality

Each project requires a specific type of Augmented Reality. Here are the main types of AR:

• Marker-based AR uses a visual marker to trigger an interactive experience. When the image is scanned with a device’s camera, it activates special effects or animations.
• Markerless AR doesn’t use a physical marker, but rather location-based data like GPS to track the user’s settings and detect the location of the virtual content. Users simply scan their surroundings with a smartphone to integrate digital elements into the real world.
• Projection-based AR uses a stationary projector to overlay 3D visuals onto the physical space. Instead of creating a fully immersive environment, it projects holograms that blend digital and real elements.
• Superimposition-based AR replaces real-world objects with digital overlays. It’s often used for navigation and guidance, such as helping customers visualize products or directions inside a physical store.

Real-World Examples / Use Cases

Different types of AR serve different purposes across industries. The most common applications are in eCommerce and retail, where buyers can preview products from every angle before purchasing. In healthcare and education, AR enables the creation of detailed 3D models for training and learning. AR-powered virtual tours let users explore properties remotely, while immersive gaming experiences have transformed entertainment through realistic and engaging interactions.

Common Questions About AR Functionality

What devices support AR?

AR typically works on smartphones, tablets, AR glasses, and headsets. However, Vizbl removes the usual hardware barriers by running entirely in the browser on any smartphone or tablet with a camera. There’s no need for specialized devices, apps, or installations, making AR experiences instantly accessible to anyone.

How accurate is AR?

Even though AR accuracy depends on the hardware, software, and settings, working with Vizbl ensures consistent, real-time precision through markerless, browser-based tracking. The platform maintains stable object placement and realistic visualization even under varied lighting conditions and environments.

What skills are needed to work in AR?

Traditional AR development requires skills in 3D modeling, programming (e.g., C# or C++), and SDKs like ARKit or ARCore. With VIZBL, all rendering and placement are automated, eliminating the need for coding or SDK integration and allowing teams to focus on design and content.

Why choose Vizbl for AR?

VIZBL is a web-based AR platform that works instantly in any browser. It requires no coding, apps, or special hardware, making it easy for businesses to create and share realistic 3D and AR experiences in minutes.
