HTML5 Based Virtual Whiteboard for Real Time Interaction

Meetings and classrooms demand the presence of the person in the room if he wants to participate. A tool widely used in such places is a whiteboard. A whiteboard has limited creativity and interactivity options and hence it needs to be replaced with better tools. In this paper we develop a web application to increase collaboration without restricting him to any location, operating system platform or device. Our application allows users to interact and share information via drawings, images, chat, audio and video. They can create individual rooms and share the room id with only certain people. Users only need access to web browsers and internet to make use of the application. There is no limit on the number of users allowed to participate and no plug-in needs to be downloaded. We have implemented this system by using HTML5, Node.js and WebSocket. WebSocket support concurrency in real-time transmission of information. All the users can simultaneously interact with the system. The experimental results demonstrate the high scalability of our system. As evident from the experiments, the response delay is extremely low, the system is fast and provides real-time experience to the users.
