Abstract: In the modern age, most of the laptops are without CD-ROM, but a huge amount of teaching material like video, audio and text information are still available on Compact Disk (CD). Exclusion of CD-ROM creates problems for the students to get video lectures and other electronic information from Compact Disk. Considering the above problems, this paper solves it with the implementation of the mobile augmented reality application, which is called VBook. The proposed solution is based on Unity3D development tools and Vuforia SDK expansion of real-world software development kit to achieve the objective. First, the application accesses the mobile camera to get the pictures and performs image recognition with Vuforia SDK. The recognition maps are generated and saved as a database, and meanwhile named as videos accordingly. Secondly, the application designs scenarios using Unity3D and downloads Vuforia toolkits package integrated in Unit3D, and after that, programs the recognition codes to access data. The picture from the maps database is transferred to our proposed system and requested the local server to get the related video. Finally, Android application is designed. This paper uses virtual reality (Unity3D) function to access the mobile camera and video player to play the retrieved video in the focused area of the book page. The experiment shows the impressive result. Using augmented reality with Unity3D, the paper achieves the goal to provide efficient data (english learning video) availability technique.
