This is a part of the game ABC3D which we developed as a course project for Intro to Ubiquitous computing (CS 248A) at University of California, Irvine (UCI).
ABC3D consists of two modules. First module is an alphabet scanner where a user scans a letter (for example "A") and game will recognize the alphabet and display a 3D object starting with that alphabet (for example "Apple" model for “A”) over that letter using Augmented Reality.

Second module is Car game (Need For Lit), where user has to apply his knowledge from the previous module and collect some objects starting particular alphabets (like collect 5 objects starting with letter 'A'). Technologies used are Vuforia SDK and Unity 3D game engine.
Suggestions are welcome! :)
