The “Augmented Learn” application is developed to provide interactive learning with Augmented Reality for pre-school children. The application is designed for both non-AR and AR-supported devices. It serves three services: -

1. Learn
2. Test and
3. Scan book (Works only for AR-supported devices).

Learn: In this section, the app introduces (teaches) some basic subjects (i.e. স্বরবর্ণ, ব্যঞ্জনবর্ণ, সংখ্যা, Alphabets, Numbers and Animals) by playing each item name and showing the associated picture with name (If necessary) one by one by pressing a next/previous button. For every item of every learn there is available an AR view button (Works only for AR supported devices) to view the item in real-world by opening the camera of the device.

Test: In this section, the application gets a test from users which they have already learned from the Learn section. Every Test contains a set of Test pages based on the number of Test items. Each test page holds four items to choose the correct one by playing a voice that needs to choose. The examinee gets a wrong warning if the clicked item is not correct. After clicking a correct one the test page proceeds to the next one. The process is continuing until the rest of the items. All the wrong and correct answers are tracked to make a Test result.

Scan book: In this section, the app scans an item (s) for a particular subject from a dedicated Augmented Reality based book for this app to render the 3D model of the scanned item on top of it. While a user scans an item from the book the application is trying to detect the scanning image. Once the image is detected then it proceeds to track the image to render a single or multiple 3D models for each scanned item on the top of it. Note that this feature works only for AR-supported devices.
