Um den hieraus resultierenden Anforderungen besser zu entsprechen, liegt es nahe, sich intensiv mit digital gestützten Lehr-/Lernkonzepten zu befassen. Hierzu zählen z.B. auch digitale Lehrmaterialien, die, unter besonderer Berücksichtigung mobiler Endgeräte (Bitkom, 2012), in Form von interaktiven Lernmodulen distribuiert werden. Im Rahmen der eStudy-Aktivitäten des Fachbereichs Medien der FH Düsseldorf wurde eine Autorenumgebung konzipiert, die eine hocheffiziente Entwicklung von HTML5-basierten Lernmodulen mit interessanten Zusatzfunktionen erlaubt, die in vielfältigen Lehr-/Lernszenarien zum Einsatz kommen können.

The new profile UMLsec4UML2 is technically constructed as a UML profile diagram, which is equipped with a number of integrity conditions expressed using OCL. Consequently, the UMLsec4UML2-profile can be loaded in any Eclipse-based EMF- and MDT-compatible UML editing tool to develop and analyze different kinds of security models. The OCL constraints replace the static checks of the tool support for the old UMLsec defined for UML 1.5. Thus, the UMLsec4UML2-profile not only provides the whole expresiveness of UML2.3 for security modeling, it also brings considerably more freedom in selecting a basic UML editing tool, and it integrates modeling and analyzing security models. Since UML2.3 comprises new diagram types, as well as new model elements and new semantics of diagram types already contained in UML1.5, we consider a number of these changes in detail. More specifically, we consider composite structure and sequence diagrams with respect to modeling security properties according to the original version of UMLsec. The goal is to use UMLsec4UML2 to specify architectural security patterns.

We discuss the impact of Virtual Reality, Augmented Virtuality and Augmented Reality for specific memorial locations. We show how to use a virtual studio for demonstrating an augmented reality application for a specific location in a remote session within a video conference. Augmented Virtuality is used to recreate the local environment, thus providing a context and helping the participants recollect emotions related to a certain place. This technique demonstrates the advantages of using virtual (VR) and augmented (AR) reality environments for rapid prototyping and pitching project ideas in a live remote setting.

Listening to music before, during, or after sports is a common phenomenon, yet its functions and effects on performance, cognition, and behavior remain to be investigated. In this study we present a novel approach to the role of music in sports and exercise that focuses on the notion of musical self-enhancement (Elvers, 2016). We derived the following hypotheses from this framework: listening to motivational music will (i) enhance self-evaluative cognition, (ii) improve performance in a ball game, and (iii) evoke greater risk-taking behavior. To evaluate the hypotheses, we conducted a between-groups experiment (N = 150) testing the effectiveness of both an experimenter playlist and a participant-selected playlist in comparison to a no-music control condition. All participants performed a ball-throwing task developed by Decharms and Davé (1965), consisting of two parts: First, participants threw the ball from fixed distances into a funnel basket. During this task, performance was measured. In the second part, the participants themselves chose distances from the basket, which allowed their risk-taking behavior to be assessed. The results indicate that listening to motivational music led to greater risk taking but did not improve ball-throwing performance. This effect was more pronounced in male participants and among those who listened to their own playlists. Furthermore, self-selected music enhanced state self-esteem in participants who were performing well but not in those who were performing poorly. We also discuss further implications for the notion of musical self-enhancement. // Listening to music before, during, or after sports is a common phenomenon, yet its functions and effects on performance, cognition, and behavior remain to be investigated.

Until now, little has been written about the processes underlying the selection of music in daily life. The present study aimed to disentangle some of the complex processes among the listener, situation, and functions of music listening involved in music selection. Utilizing the experience sampling method, data were collected from 119 participants using a smartphone application. For 10 consecutive days, participants received 14 prompts using stratified-random sampling throughout the day and reported on their music-listening behavior. Statistical learning procedures on multilevel regression models and multilevel structural equation modeling were used to determine the most important predictors and analyze mediation processes between person, situation, functions of listening, and music selection. Results revealed that the features of music selected in daily life were predominantly determined by situational characteristics, whereas consistent individual differences were of minor importance. Functions of music listening were found to act as a mediator between characteristics of the situation and music-selection behavior. We further observed several significant random effects, which indicated that individuals differed in how situational variables affected their music selection behavior. Our findings suggest a need to shift the focus of music-listening research from individual differences to situational influences, including potential person-situation interactions.

The PSFC features realtime manipulation of the primary components of sound spatialization for each of two audio sources located in a virtual environment, including the content (apparent direction and distance) and context (room characteristics: reverberation level, room size and liveness). In an alternate mode, it can also direct the destination of the two separate input signals across 14 loudspeakers, manipulating the direction of the virtual sound sources with no control over apparent distance other than that afforded by source loudness (including no simulated environmental reflections or reverberation). The PSFC speaker dome is about 10 m in diameter, accommodating about fifty simultaneous users, including about twenty users comfortably standing or sitting near its ``sweet spot,'' the area in which the illusions of sound spatialization are most vivid. Collocated with a large screen rear-projection stereographic display, the PSFC is intended for advanced multimedia and virtual reality applications.

Users can collaborate through realtime audio, video, and drawings in a virtual space. The developed system was tested in a preliminary user study, which confirmed an increase in spatial and situational awareness among viewers as well as reduction in cognitive workload. Believing that our system provides a novel style of collaboration in mixed reality environments, we discuss future applications and extensions of our prototype.
