In this guide, you will learn what augmented reality is, how it works, the most useful augmented reality effects, real-world applications, and the differences between augmented reality and virtual reality.
What Is Augmented Reality?
Augmented reality is a technology that adds digital information to a view of the physical world. This information can include text, images, 3D objects, animations, sounds, and interactive graphics.
Unlike traditional digital content, AR does not necessarily replace your surroundings. Instead, it enhances what you can see by adding useful virtual elements.
For example, imagine pointing your smartphone at a table and seeing a digital model of a new laptop placed on its surface. You can move around the table and view the model from different angles, depending on the app's capabilities.
AR experiences can work through smartphones, tablets, wearable glasses, and other compatible devices.
According to Apple's ARKit documentation, augmented reality can place digital elements into a device's live view so they appear to exist within the real environment.
The main purpose of augmented reality is to make digital information more useful, interactive, and easier to understand.
How Does Augmented Reality Work?
Augmented reality uses a combination of hardware and software to blend digital content with the physical environment.
Here are the main technologies that make AR possible.
1. Cameras and Sensors
A camera captures images of the user's surroundings. Sensors such as accelerometers and gyroscopes help the device understand its movement and orientation.
This information allows an AR application to estimate where digital objects should appear on the screen.
2. Motion Tracking
Motion tracking helps the device understand how it moves through space.
When you move your phone, the application tracks changes in its position and orientation. This helps digital objects remain in approximately the correct place as you look around.
3. Environmental Understanding
AR software analyzes visual information to recognize surfaces such as floors, walls, and tables.
For example, a furniture app may detect the floor and position a virtual chair on it. More advanced systems can also estimate depth and understand how nearby objects relate to one another.
4. Digital Content Rendering
The software creates digital elements and displays them over the camera image.
Lighting estimation, depth information, and object tracking can help virtual objects look more natural in the real environment.
Google explains these capabilities in its ARCore fundamentals guide.
However, AR is not perfect. Poor lighting, reflective surfaces, limited camera quality, and unsupported hardware can reduce accuracy.
