This tutorial aims to guide you on how to enhance customer interaction through Augmented Reality (AR). AR has proven to be a powerful tool to engage customers and provide unique, immersive experiences.
By the end of this tutorial, you will be able to:
Augmented Reality (AR) integrates digital information with the user's environment in real time. The two main libraries we will use are A-Frame (a web framework for building VR experiences) and AR.js (a solution for efficient AR on the web).
2.1 A-Frame
A-Frame uses an entity-component-system pattern that promotes composition and extensibility. It is easy to get started with and it works well with other libraries and frameworks.
2.2 AR.js
AR.js is a lightweight library for AR on the web, with a very simple setup. It's less than 10% of the size of the Unity3D file for the same AR functionality.
Example 1: Basic AR application
Let's start by creating a basic AR application that places a 3D model in the real world.
<!-- Include A-Frame and AR.js libraries -->
<script src="https://aframe.io/releases/1.0.4/aframe.min.js"></script>
<script src="https://jeromeetienne.github.io/AR.js/aframe/build/aframe-ar.js"></script>
<body style='margin : 0px; overflow: hidden;'>
<a-scene embedded arjs>
<!-- 3D model -->
<a-entity
position="0 0 0"
scale="0.05 0.05 0.05"
gltf-model="url_to_your_model.gltf">
</a-entity>
<!-- Marker -->
<a-marker-camera preset='hiro'></a-marker-camera>
</a-scene>
</body>
Explanation:
arjs
attribute to enable AR.a-entity
element. You can replace "url_to_your_model.gltf"
with the URL to your 3D model.Expected Output:
When you point your device's camera at a Hiro marker, you should see the 3D model appearing on top of the marker.
We've covered the basics of AR.js and A-Frame, and how to create a simple AR web application. This is a stepping stone to creating more complex AR experiences to engage your customers.
Exercise 1
Create an AR application that displays a 3D model of a product when the camera points at a specific image.
Exercise 2
Create an AR application that displays different 3D models when the camera points at different markers.
Solutions and Tips
For these exercises, you will need to create custom markers and link them to your 3D models. You can create custom markers using the AR.js Marker Training tool.
Remember to test your applications on different devices to ensure they work as expected.
