    abstract    = {The rapid evolution of computer technologies entails that those technologies become available to a broader audience as we go along. But with new technologies new challenges arise. Especially in the education sector Information and Communications Technology (ICT) is used to enhance the learning process and to support the learner. Recent times have shown that multi-touch enabled devices become more and more attractive to the user, but force the users to turn away from each other and focus on their own multi-touch display. With the introduction of interactive tabletop hardware multi-touch interaction is taken to the next level since large displays allow and invite not just one but multiple users at the same time. However that presents designers and developers with new challenges in terms of how to use the interaction possibilities and the workspace offered by such large displays best in order to support active collaboration and information sharing in an education scenario.

    This thesis evaluates the use of Natural User Interface (NUI) and Tangible User Interface (TUI) design principles in the process of interactive co-located collaboration in technology-enhanced learning activities. For this purpose, an interactive tabletop application with Microsoft Surface in the context of digital storytelling was implemented. Based on this tabletop prototype, a user interaction study with ten participants was conducted. The evaluation considered the users' subjective reaction and acceptance for those User Interface (UI) paradigms as well as their level of collaboration and communication. The results indicate that the use of a NUI on large interactive tabletops supports co-located collaboration and encourages the exchange of information. However, although the use of a TUI can provide added value to the prototypes' operating principles, its suitability for co-located collaboration could neither be approved nor disproved based on the current study. Finally, the thesis proposes solutions for the found problems as well as further recommendations for future work.}
