Abstract:
We present a concept and implementation on increasing the efficiency of webinar software by a remote control approach using the technology WebRTC. This technology enables strong security and privacy, is cross-device usable, uses open-source technology and enables a new level of interactiveness to webinars. We used SlideWiki, WebRTC, and browser speech to text engines to provide innovative accessibility features like multilingual presentations and live subtitles. Our solution was rated for real world usage aspects, tested within the SlideWiki project and we determined technological limits. Such measurements are currently not available and show that our approach outperforms open-source market competitors by efficiency and costs.
