Build Interactive AR Tutor App

The AR learning app is an educational app that uses Augmented Reality technology to provide an interactive learning experience for students. The app allows users to learn about different animals or plants by placing them in a virtual world, where they can interact with them and learn more about their characteristics. The app uses augmented reality technology to overlay 3D virtual objects onto real-world images and videos. Students can use the app to learn about science topics through experiments, including chemical reactions and the effects of gravity on objects and similar many other concepts.

AR is a new technology that is being adopted by many developers and businesses. We have seen many examples of AR applications that have been developed. This AR learning application is built using the A-Frame framework. This app will help you learn how to create an augmented reality app using A-Frame and VSCODE, etc.

Please see below a sample solution kit to jumpstart your solution on the AR Learning Kit. To use this kit to build your own solution, scroll down to the Kit Deployment Instructions sections.

Instruction to run:

Follow below instructions to run the solution:

1. Locate and open the respective extracted zip file.
2. Open the command prompt and start your local HTTP server with Python by using the command "python -m http.server 8000," or you can deploy this in any other web server also.
3. Use the "G" marker, i.e., available in the assets folder or you can download here. Show the marker to the application, and then see the 3d image in the browser. (can use the print-out-based marker or marker can be downloaded in your mobile and can also show the same).
4. The application currently has 15 models. Refer the same under < a-assets > in the "index.html" file. You can replace any of the 3d models with your own model.
5. Use left arrow and right arrow available on the screen to experience the models. Zoom in option is also available in the application.

For changing the images for your topics,

Create your own 3d images related to the themes that you would like to explain with AR features.

1. To add your 3d models, follow below procedure:

• The 3d models should be in the format of ".gltf"
• If your 3d model contains a single file, then place the same directly in the assets folder i.e., available under the "AR-Alphabets-master" folder otherwise if your 3d model contains multiple files, then create a folder with the respective name inside assets and place the files in the folder.
• Then go to the "index.html" file and update the src attribute accordingly Example :- src="assets/3d-model-name.gltf" or src="assets/your-folder-name/3d-model-name.gltf"
• To place your 3d model, some more helpful comments are available under < a-assets > in "index.html" file. Note:- To experience your 3d models, you should run the application on your local web server mode only. For information about creating the 3d models, kindly refer to the Creation of 3d Model Repository section.

2. You can change the size of the 3d models by adjusting the scale values in "main.js" (eg:-scale: "0.2 0.2 0.2")

3. You can also change the voice assistant corresponding to the 3d image by changing the description name in "main.js" (eg:-description: "Earth")

4. Once changes are done, make sure to restart the application for the changes to be effective.

5. Now, you will experience your theme with AR in your Environment!

Creation of 3d Model Repository

1. You can create your own 3d models by using open source IDE like unity3d, Blender, AutoCAD or you can get 3d models from open source websites given below

• Creazilla, Eg:- Camel
• Sketchfab

Note:- Kindly check the license of the 3d models before using them.

2. Make sure that 3d models should be in the form of ".gltf" format, if not so kindly change them to the respective format. You can refer to the below links to convert your 3d models in the ".gltf" format.

• fbx-to-gltf
• obj-to-gltf

Troubleshooting

1. While running batch file, if you encounter Windows protection alert, select More info --> Run anyway
2. During kit installer, if you encounter a Windows security alert , click Allow

Development Environment

Visual studio code IDE is used for this development. It becomes easy to modify the code and the configuration with Visual studio code.

AR Libraries

A-Frame is an open-source web framework used for building Augmented reality (AR) experiences. In the spirit of open-source software development, jQuery plays a vital role in community code contribution.

The below library could be used to create jQuery scripts and respective models.
