Abstract

In diesem Artikel wird die Entwicklung einer Lernanwendung zur strukturierten Zerlegung in der Informatik nach dem Lebenszyklusmodell beschrieben. In drei Entwicklungszyklen werden dabei Experten befragt und die Prototypen mit Grundschulkindern evaluiert. Zur Unterstützung der Kollaboration erfolgte die Entwicklung für ein Tabletop-System.

Abstract

Touch-based user interfaces are increasingly used in private and professional domains. While touch interfaces have a high practicability for general daily applications, it is a central question if touch based interfaces also meet requirements of specific professional domains. In this paper we explore the applicability of touch gestures for the domain of medical imaging. We developed a set of intuitively usable gestures, applicable to different screen sizes. The development was entirely user-centered and followed a three-step procedure. (1) The gesture set was developed by asking novices to propose possible gestures for different actions in medical imaging. (2) The gesture set was implemented in a commercial medical imaging solution and (3) evaluated by professional radiologists. The evaluation shows that the user-centered procedure was successful: The gestures did not only work equally well on different screen sizes, but revealed to be intuitive to use or easy to learn. © 2013 Springer-Verlag Berlin Heidelberg.

Abstract

In this study, we address the problem of low retention and high dropout rates of computer science university students in early semesters of the studies. Complex and high abstract mathematical learning materials have been identified as one reason for the dropout rate. In order to support the understanding and practicing of core mathematical concepts, we developed a game-based multitouch learning environment in which the need for a suitable learning environment for mathematical logic was combined with the ability to train cooperation and collaboration in a learning scenario. As application domain, the field of mathematical logic had been chosen. The development process was accomplished along three steps: First, ethnographic interviews were run with 12 students of computer science revealing typical problems with mathematical logic. Second, a multitouch learning environment was developed. The game consists of multiple learning and playing modes in which teams of students can collaborate or compete against each other. Finally, a twofold evaluation of the environment was carried out (user study and cognitive walk-through). Overall, the evaluation showed that the game environment was easy to use and rated as helpful: The chosen approach of a multiplayer game supporting competition, collaboration, and cooperation is perceived as motivating and ?fun.?
