Design and implementation of Android-based interactive multimedia presentation platform for multiple users

With the development of multimedia and embedded system technologies, it gradually becomes the part of our life. The course materials in future classrooms will be presented by interactive multimedia. It is different from the previous traditional teaching. The paper proposed two concepts about multiple users´ interaction and multiple users´ operating. Our system integrates cloud management system, multiple remote joysticks and android-based presentation platform. This system is divided into two parts: Interactive Multimedia Presentation Platform (IMPP) and Cloud Service Center (CSC). Our Android and Unity3D interactive library are developed for third-party users. Users can develop a multi-user interactive app on our system easily. CSC is a website, which is based on Drupal open source. The Application Store of Embedded Multimedia Network (EMNA Store) was approached. Users can download, install and delete apps on EMNA Store from IMPP. Finally, the multiple interactive presentation system with cloud services was realized.
