Hochschulen für angewandte Wissenschaften (HAW) spielen eine entscheidende Rolle in der deutschen Bildungslandschaft. Sie zeichnen sich durch ihre praxisorientierte Ausrichtung aus und sind maßgeblich daran beteiligt, den steigenden Bedarf an hochqualifizierten Fachkräften in verschiedenen Branchen zu decken. Um diese Aufgabe erfolgreich zu bewälti...

Avatars are in use when interacting in virtual environments in different contexts, in collaborative work, as well as in gaming and also in virtual meetings with friends. Therefore it is important to understand how the relationship between user and avatar works. In this study, an online survey is used to determine how the perception of an avatar cha...

Lehre und Lernen unterliegt einem stetigen Wandel, wobei Interaktion als ein zentrales Element der Motivationssteigerung im Lernkontext angesehen wird. Der vorliegende Beitrag zeigt verschiedene Ansätze zur Gestaltung von interaktivem und kollaborativem Lehren und Lernen in einem virtuellen Klassenzimmer auf und stellt ein Beispiel für die Umsetzun...

JumpAR kombiniert die Welt der Augmented Reality (AR) mit dem weltbekannten Jump ’n’ Run Genre in einem Mobile Game. Der Spieler kreiert einen individuellen Spielparcours in seiner realen Umgebung und navigiert seine Spielfigur auf virtuellen Plattformen durch diesen. Der mit Unity entwickelte JumpAR Prototyp wurde nach Umsetzungen der Grundfunktio...

In diesem Beitrag wird ein neuer Ansatz vorgestellt, welcher eine schwerkraftre-duzierte Navigation innerhalb einer VR-Umgebung erlaubt, wie beispielsweise ein simulierter Mondspaziergang. Zur Navigation in der VR-Umgebung wird der Cyberith Virtualizer ein-gesetzt. Die Schwerkraftsimulation erfolgt mittels eines einstellbaren Gurtsystems, das an el...

Using the term Innovation Enabling this paper introduces a holistic concept to support interdisciplinary teams in creative and innovative problem-solving tasks. The concept supports both facilitators and participants and is based on implicit interactions. A central element of the concept is the Awareness Pipeline. It is used to implement implicit i...

A large body of literature is concerned with models of presence-the sensory illusion of being part of a virtual scene-but there is still no general agreement on how to measure it objectively and reliably. For the presented study, we applied contemporary theory to measure presence in virtual reality. Thirty-seven participants explored an existing co...

This paper provides insights into a prototype in a field we call „Innovation Enabling“. The prototype is based on multiple round group tables, equipped with projectors and RGBLED-strips. The tables make brainstorming sessions an effortless experience for both the participants as well as the moderator by automating recurring tasks like group-buildin...

The increasing heterogeneity of students at German Universities of Applied Sciences and the growing importance of digitalization call for a rethinking of teaching and learning within higher education. In the next years, changing the learning ecosystem by developing and reflecting upon new teaching and learning techniques using methods of digitaliza...

Engineers of the research project “Digital Product Life-Cycle” are using a graph-based design language to model all aspects of the product they are working on. This abstract model is the base for all further investigations, developments and implementations. In particular at early stages of development, collaborative decision making is very importan...

In this paper we suggest an ubiquitous system with an implicit HCI. A basic concept of a middleware as well as design recommendations for future creativity and collaboration environments in an engineering context are presented in this paper.

This paper presents an approach to develop a collaborative working environment for engineering support in the field of model-based systems engineering. The need for such a system is motivated and a concept for an adaptive CSCW environment is shown.

Accuracy of optical tracking systems are typically performed through comparing calculated positions based on sensory data with a known coordinate system. A special measuring environment is usually required in order to obtain data from these systems. In this study, a comparative evaluation of two 3D optical tracking systems is presented: WorldViz Pr...

The aim of this work is to increase the effectiveness of real world medical training simulations by helping trainees gain a better understanding of the importance of communication and teamwork. Therefore we develop an online application which can be used together with real world simulations to improve training. To produce the online application we...

Medical training centers often provide vari-ous simulations for students and professionals. Their goal is not only to make trainees practice specific scenarios but also to help them effec-tively transfer the acquired skills to the real world. Having in mind that virtual environments have already been acknowledged for their po-tential to improve the...

This paper presents INSYDER, a contentbased visual-information-seeking system for the Web. The Web can be seen as one huge digital library offering a variety of very useful information for business analysts. INSYDER addresses these possibilities and offers powerful retrieval and visualisation functionalities. The main focus during the development w...
