A Multimedia Application System Supporting Interactive Control Of Mobile Terminal

Multimedia interactive applications have always been popular with people,it can be a fun way for users to stand in a new perspective to experience the event which may occur in our daily life,or even the things which are in the imagination.The multimedia interactive applications we developed,not only allows users to have a good experience,and each application has its own unique advantages.With the full arrival of the mobile Internet era,people prefer to use mobile devices to control the life of all aspects.So this paper designed a multimedia applications system which support interactive control of mobile terminal,the system consists of mobile terminal App,the central control server and various types of interactive applications,media control server.The whole system has strong scalability,low coupling between different modules.It is suitable for large-scale places such as science and technology exhibition halls and playgrounds.In this paper,the mobile terminal program is developed by Xamarin;interactive applications are developed by Unity3D.The main work and contributions of this paper are as follows:? Designed a system framework,designed the communication control protocol between the total mobile control terminal and the central control server,and participated in the design and discussion of some functions of the central control server.? Based on this system framework,developed a mobile terminal App,which is used to control the program and equipment in the whole system.?Developed a Kinect-based interactive applications "Run for fun",including the automatic generation of the scene,real-time speed synchronization of treadmill,design of the somatosensory game,and the corresponding mobile terminal control App.Put run,game,interactive these three elements into together.? Developed a Kinect-based interactive applications "Interactive book",compared to other applications of the same type,the biggest advantage lies in its judgments of the open book action can reach 95%accuracy,can effectively distinguish user in the end is conscious or unconscious to open the book.?Developed a multi people multi-screen interactive application "New interactive photo wall",including the design and implementation of 2D and 3D random spanning tree algorithm,and the corresponding mobile terminal control App,users can share and interact on the big screen by their own devices in the public space.
