Browsing E-Lecture Libraries on Mobile Devices: A Spatial Interaction Concept

Increasingly powerful mobile devices like the Apple iPhone empower learners to watch e-lectures not only at home but also in mobile learning scenarios virtually anywhere and anytime. However, state of the art mobile video browsers do not support learners in getting an overview on and navigating between the large amounts of semantically related e-lectures, which are available in various digital libraries. We contribute a novel user interface for the mobile use of e-lectures. Leveraging a spatial navigation metaphor, it supports both linear and nonlinear interaction within a single lecture, as well as the efficient navigation within large e-lecture libraries. Evaluation results show that our e-lecture browser significantly improves the learning process and leads to significantly higher efficiency and user satisfaction.
