Collaborative drawing annotations on Web videos

Abstract

Collaborative Drawing over a computer network, in particular on videos, usually requires some complex client-server architecture. In this paper, we want to demo an approach with the following distinctive features. On the client side we enable peer-to-peer collaborative video drawing in recent Web browsers supporting WebRTC. Developers can therefore embed it in arbitrary Web pages and users do not need to install any additional software. For persistence we use a microservice driven cloud approach which can be set up easily. All components are open source to facilitate wide use and further development. A use case evaluation showed promising results and will be presented in the demo.
