Improving Interaction During Lectures: A Minimal-Distraction Approach

In the Digital Lecture Halls project, venues on campus are augmented with novel computer based tools. Learners with mobile devices are particularly supported. The project emphasizes improved learner experience by carefully evaluating benefits and drawbacks of the technology introduced. This paper discusses a multifunctional software tool called TVremote, intended to support interaction in large and distributed venues while minimizing distraction from the ‘flow’ established between teacher and learners. The tool integrates a number of prevailing interaction concepts under a common concept with minimal cognitive overhead. Substantial effects on overall interactivity, learner experience, teaching style, and sustainable teaching improvements could be shown in a first qualitative evaluation after a few months of regular use in class.
