Now day’s children are more likely to use smartphones. They would like to use smartphones more than a textbook. They use smartphones for playing various games and watch the cartoon as well as funny videos and movies also. The addiction to using smartphones through children is increasing day by day. Maximum parents now want to teach their children via smartphones. In that case, they try to find various learning apps and games. From that sense, we decide to make a child learning apps by using Augmented Reality & Virtual Reality. AR & VR is the most powerful way of interaction nowadays. On AR apps we design an alphabets book for the children according to our survey report and we make an android app using unity 3D. When a child opens the apps, then the phone camera will open. And if the child holds the camera in any picture of the book, then the smartphone will tell the name of the alphabet and also tell a word with that particular word and will show a 3D visual model of the object on the mobile display. And on the VR apps, we design some 3d environments according to our survey. Inside the environment, there will some alphabets in some fixed placed according to sequence and the child has to collect them by walking inside the environment. When he/she pick any alphabet than the apps will tell the name of the alphabet.
