Improving Speaker Training with Interactive Lectures

Feedback has always been a cornerstone of the learning process. Advances in mobile devices and wireless connectivity promise closer and better feedback between speakers and audiences. In this paper we discuss a system allowing both real-time and reflective feedback for speakers. By means of online video annotations the audience can augment a lecture with personal notes and give the speaker valuable feedback both instantaneously and retrospectively. The strengths and weaknesses of the system based on lecture hall experiments are presented and discussed.
