In this tutorial, we will explore how Augmented Reality (AR) can be used to boost sales for a variety of businesses. AR is the integration of digital information with the user's environment in real time, and it's becoming increasingly popular in marketing and sales.
What Will You Learn?
Prerequisites
Augmented Reality (AR)
AR overlays digital content onto the real world, providing an immersive experience that can engage customers and boost sales. For example, a furniture store could use AR to allow customers to visualize how a piece of furniture would look in their home.
A-Frame
A-Frame is a web framework for building virtual reality (VR) experiences. It's built on top of Three.js and WebGL, and it's compatible with most AR hardware and software.
AR.js
AR.js is a lightweight library for AR on the web, with a very simple and intuitive API. It's compatible with A-Frame and allows you to create AR experiences that work in any browser and on any device.
Here's a simple example of an AR scene using A-Frame and AR.js.
<!DOCTYPE html>
<html>
<head>
<!-- Include A-Frame and AR.js libraries -->
<script src="https://aframe.io/releases/1.2.0/aframe.min.js"></script>
<script src="https://jeromeetienne.github.io/AR.js/aframe/build/aframe-ar.js"></script>
</head>
<body>
<!-- Create an AR scene -->
<a-scene embedded arjs>
<!-- Add a 3D model -->
<a-entity
gltf-model="url_to_your_model.gltf"
scale="0.5 0.5 0.5"
position="0 0 -5"
rotation="0 180 0"
></a-entity>
<!-- Add a marker -->
<a-marker-camera preset="hiro"></a-marker-camera>
</a-scene>
</body>
</html>
You should see your 3D model overlaid onto the real world when you point your device's camera at the Hiro marker.
This example shows how to make your AR scene interactive.
<!DOCTYPE html>
<html>
<head>
<!-- Include A-Frame and AR.js libraries -->
<script src="https://aframe.io/releases/1.2.0/aframe.min.js"></script>
<script src="https://jeromeetienne.github.io/AR.js/aframe/build/aframe-ar.js"></script>
</head>
<body>
<!-- Create an AR scene -->
<a-scene embedded arjs>
<!-- Add a 3D model -->
<a-entity
gltf-model="url_to_your_model.gltf"
scale="0.5 0.5 0.5"
position="0 0 -5"
rotation="0 180 0"
onclick="this.setAttribute('scale', '1 1 1')" // Make the model grow when clicked
></a-entity>
<!-- Add a marker -->
<a-marker-camera preset="hiro"></a-marker-camera>
</a-scene>
</body>
</html>
In this example, the 3D model will grow when you tap on it.
In this tutorial, we've learned about the basics of Augmented Reality (AR) and how it can be used to boost sales. We've also seen how to create simple AR experiences using A-Frame and AR.js.
Next Steps
Additional Resources
Exercise 1
Create a basic AR scene with a different 3D model.
Solution
Replace "url_to_your_model.gltf" with the URL of your new 3D model.
Exercise 2
Make the 3D model rotate when you tap on it.
Solution
Replace "this.setAttribute('scale', '1 1 1')" with "this.setAttribute('rotation', '0 360 0')".
