【摘 要】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 Unity 3D development tools and Vuforia SDK expansion of real-world software development kit to achieve the objective.First,the applica-tion 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 u-sing Unity3D and downloads Vuforia toolkits package integrated in Unit 3D,and after that,programs the recognition codes to ac-cess data.The picture from the maps database is transferred to our proposed system and requested the local server to get the relat -ed video.Finally,Android application is designed.This paper uses virtual reality(Unity3D)function to access the mobile cam-era 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.%由于当前大多数笔记本电脑不再配置光驱,但英语教材依然以光盘形式提供视频资料,影响学习效果,因此采用U-nity3D集成Vuforia SDK设计实现基于增强现实技术的英语视听说移动教学软件VBook.系统首先构建识别图数据库存于云端,根据识别图名称命名对应的视频文件;然后利用Unity3D设计和渲染场景,设计ImageTarget对象的虚拟视频播放按钮,编写脚本代码实现对识别图数据库及其相应视频的访问;最后生成便于用户使用的移动端应用.用户只需将Camera镜头对准书本插图,即可呈现出虚实叠加的视觉效果,实现移动设备的英语教学视频播放.将增强现实技术应用于英语视频教学,能使用户享受到新颖的学习方法和虚实结合的交互体验. 【总页数】5页(P122-126) 【作 者】黄敏;兰红
