Learning to develop in AR allows for a deep understanding of how virtual content interacts with the real world, fostering innovation and problem-solving. Furthermore, it can be a rewarding experience that helps you personalize your learning journey and enhance your projects with interactive features.
Understanding the Basics of AR
Before diving into the development process, let’s establish a solid foundation by understanding the core principles of augmented reality. At its heart, AR is a technology that overlays computer-generated imagery onto the real world, enhancing the user’s perception of reality. Think of it as adding a digital layer to what you already see.
AR differs fundamentally from Virtual Reality (VR). VR immerses users in a completely simulated digital environment, blocking out the real world. AR, on the other hand, blends digital content with the existing environment, letting users interact with both simultaneously. This characteristic makes AR ideal for applications like interactive tutorials, product visualizations, and games that integrate with real-world surroundings.
Several core concepts underpin the functionality of any AR system. Tracking is crucial; it enables the AR system to understand the user’s position and orientation in the physical space. Tracking technologies include visual tracking (using the device’s camera to recognize features in the environment), GPS (for outdoor location-based AR), and inertial measurement units (IMUs) that provide information about the device’s movement. This information allows the system to position the virtual content accurately within the real-world view.
Rendering is the process of displaying the digital content. It involves creating or importing 3D models, textures, and animations, and then placing them within the user’s field of view. Advanced rendering techniques such as realistic lighting and shadows are often employed to make the digital objects appear seamlessly integrated with the physical world.
Interaction is what brings AR to life. This encompasses how users engage with the augmented content. This can range from simple taps and gestures on a touchscreen to more advanced interactions using voice commands or hand tracking. Creating engaging interaction design is crucial to deliver a smooth and immersive AR experience. The best user interfaces are intuitive and add value to what the user is seeing.
Various platforms cater to AR development, each with its strengths and weaknesses. These are tools you can use to construct your very own **AR kit**:

This offers the benefit of immediate accessibility, making it easy to test and iterate on your ideas. Mobile AR development is generally more straightforward to get started with compared to other platforms, reducing the initial learning curve. Moreover, the cost is kept to a minimum because you leverage devices you may already own.
Web AR is a very good entry point for beginners. By designing your AR experiences around web browsers, you will open up the possibility for your users to easily access the final product. If your **AR kit** is meant for sharing widely, this is one of the best options.
The cost of development can vary greatly depending on the complexity of the project and the hardware you select. If you are building your own **AR kit**, be sure to stay within your budget while still having a quality experience.
To develop for mobile AR, you’ll primarily use software development kits (SDKs) specific to the operating system of your target devices. ARKit from Apple and ARCore from Google are the dominant choices for mobile AR development.
For Web AR, you can consider using Javascript libraries such as AR.js and WebARonAR.
Unity and Unreal Engine are professional-grade game engines that are often used to build AR applications for various platforms. These engines offer robust tools and capabilities, but they may have a steeper learning curve for beginners.
Setting Up Your Development Environment
Regardless of the platform you choose, the initial steps involve setting up your development environment, which serves as the foundation for creating your AR experiences.
Let’s walk through the general steps, using Unity as an example. Before beginning, you’ll need to install the following:
- A compatible version of Unity Hub, which will manage your Unity installations.
- Choose the correct platform for your development: Android Studio for Android development, and Xcode for iOS development. You can download these from their respective websites.
Here’s a more detailed step-by-step process:
Download and Install
Visit the Unity website and download the Unity Hub. Install it on your computer, following the on-screen instructions. Within Unity Hub, install the latest recommended version of Unity.
Install the Necessary Support for Your Development Platform
Depending on the platform you are targeting (iOS or Android), you need to install the appropriate support. In the Unity Hub, navigate to “Installs,” select your Unity version, and click the gear icon. Then, choose to “Add Modules”. Select the platform modules that you need and click install.
Create a New Unity Project
Open Unity Hub and create a new project. Choose the “3D” template, give your project a descriptive name (e.g., “MyFirstARProject”), and specify the save location.
Import AR Packages
After creating your project, you’ll need to install the necessary packages for AR development. For Unity, you can choose from ARFoundation, ARKit XR Plugin, and ARCore XR Plugin (found within the Package Manager in Unity).
Configure the Project for the Target Platform
Go to “Build Settings” (File > Build Settings). Select your target platform (Android or iOS). Then, navigate to “Player Settings”. Configure important settings such as the package name, company name, minimum Android API level, and capabilities.
