An HTML5 Player for Interactive Non-linear Video with Time-based Collaborative Annotations

With HTML5 becoming more and more standardized, it is possible to implement platform independent applications running on smartphones, tablets, laptops, and desktop PCs with different operating systems and screen resolutions. A combination of HTML5 with CSS and JavaScript allows the implementation of appealing user interfaces with advanced functionality. In this paper we present an HTML5 player for interactive non-linear videos using these technologies. In addition to standard player functions, our player provides extended navigation (button panels, table of contents, keyword search) in the video, areas for additional information, opportunities for collaboration, and a logging function. The latter allows analyses of the user behavior for further research questions. We also address first user studies.
