Transparent teleteaching

Today's teleteaching software restricts teaching in the way that it only supports a specific presentation application and a single platform. This is a major drawback and a reason why teleteaching is not that widespread as it could be. Therefore we have created a teleteaching environment, called TeleTeachingTool, which enables lecture recording and transmission to be done transparently to teaching. Our tool allows teachers to use arbitrary software including their preferred presentation tool running on their favorite platform. It combines desktop recording with real-time audio and video streams to a recordable and online presentable lecture. In this paper we will discuss the requirements of teleteaching, describe our teleteaching environment and compare it with other teaching software.
