CUBELEARN — Augmented Reality Educational Game
UnityC#Vuforia
Augmented RealityAndroidGame Design
Educational mobile game designed to teach programming concepts to children through physical interaction. Players scan AR markers (Vuforia) with their device camera to trigger actions — characters on screen move accordingly. Each board presents a challenge: guide the fire truck to extinguish the fire by arranging markers in the correct sequence, applying concepts like ordered instructions and loops. Built with Unity and C#, compatible with Android 4.0+.
Want to try it? Install the APK and point your camera at the markers shown in image 3 (Instructions): right, left, up, down — or the loop marker to repeat a sequence.
