  abstract = {Naturally, university courses should be designed to attract students, engaging them to achieve learning goals. Toward this end, the use of Serious Games has been proposed in the literature. To address positive effects, such as content memorability and attendance rates, we propose Ambient Serious Games as games embedded in a computer-enriched environment, which is only partially perceived mentally by players. In this paper, we describe five technological key challenges that must be overcome to seamlessly and beneficially integrate an Ambient Serious Game into teaching. These challenges, derived from a scenario, focus on the technological provision and conduct of such games based on a software platform. They include (1) the integration of physical smart learning objects in heterogeneous environments under dynamic constraints, (2) the representation of abstract subject matter using smart learning objects, (3) the guided or automatic connection of all involved components, (4) the explanation of the components, their interaction, as well as the serious game itself, and (5) feedback on the game state.},

abstract = { Today’s Augmented Reality (AR) technology allows users to explore the real world enriched with digital artifacts, learn from it, or shape it (i.e., creating your own virtual objects). To properly use virtual objects in AR space, users must be able to manipulate them (i.e., rotate or move them). The prerequisite for manipulation is an intuitive interaction technique controlled by an input device. To explore novel AR interaction techniques, a new ball-shaped input device called BIRDY is combined with the HoloLens for the first time. This paper presents findings regarding this combination of devices. Four new interaction techniques were designed that benefit from BIRDY’s orientation invariance. Aiming to identify promising interaction rules, a prototype was developed to evaluate these interaction techniques. Results indicate that using gravity as a placement tool and separating the degrees of freedom when manipulating virtual objects provides the best experience for users. Findings further confirm the potential of using ball-shaped devices for interaction in AR.},

abstract = { In the past decade, pervasive environments have emerged from promising research concepts to available products present in our everyday lives. By connecting multiple smart objects, device ensembles can be formed to assist users in performing tasks. Furthermore, smart objects can be used to control applications, that, in turn, can be used to control other smart objects. While dynamically connecting these components allows for solutions tailored to the needs and respective tasks of a user, it obfuscates the handling and ultimately may decrease usability. Self-descriptions have been proposed to overcome this issue for ensembles of smart objects. For a more extensive approach, descriptions of applications in pervasive environments need to be addressed as well. Based on previous research in the context of self-explainability of smart objects, we propose a description language as well as a framework to support self-explaining ambient applications (applications that are used within smart environments). The framework can be used to dynamically connect smart objects as well as ambient applications and to realize self-explainability for these interconnected device and application ensembles. },

  abstract = {Rufsystem 4.0 in der Intensivpflege – Brücke zwischen Patienten und Pflegenden

Klassische Patientenrufsysteme sind elektronische Meldesysteme, die – beispielsweise in Krankenhäusern – genutzt werden, um Pflegenden über optische Signale Anliegen von Patientinnen und Patienten aufzuzeigen. Dies erfordert, dass Pflegende nach Wahrnehmung des Rufes aktiv in das Patientenzimmer gehen und im Gespräch die konkreten Anliegen abfragen müssen. Problematisch ist dies bei beatmeten Intensivpatienten im Weaning, die in ihrer Kommunikationsfähigkeit stark eingeschränkt sind und so ihre Anliegen nur mit unterstützter Kommunikation mitteilen können. In dieser Interaktion zwischen Pflegenden und Weaning-Patienten fehlen effektive Methoden zur unterstützten Kommunikation, und daher wird diese Kommunikation oftmals als belastend empfunden [1].

Im Rahmen des multidisziplinären Verbundprojekts ACTIVATE wird ein soziotechnisches interaktives System zur Förderung der Re-Orientierung von und Kommunikation mit beatmeten Patienten – insbesondere in der Weaning-Phase – entwickelt. Dazu wird unter anderem ein Modul zur Optimierung der Fernkommunikation in Form eines innovativen Rufsystems erforscht und entwickelt. In unserem Konzept können Patienten ihr Anliegen basierend auf einem Themenkatalog spezifizieren und drahtlos eine entsprechende Nachricht senden. Das System organisiert dabei entsprechend automatisch die jeweilige Zuordnung an das korrekte mobile Endgerät der zuständigen Pflegekraft unter Berücksichtigung von Kontext, Status und Aufgabenverteilung. Hierzu steht den Patienten ein spezialisiertes Eingabegerät zur Verfügung. Pflegende können den Eingang der Nachricht bestätigen und über das System Feedback – beispielsweise eine Lesebestätigung – senden.

Für das Personal bietet das Konzept die Vorteile, dass unnötige Wege eingespart werden können und eine umständliche Erfragung der Anliegen entfällt oder vereinfacht wird. Patienten profitieren ebenfalls von der Möglichkeit, Anliegen einfacher mitzuteilen. Das Feedback kann Ungewissheit reduzieren, ob der Ruf wahrgenommen wurde. Dabei wird auf Basis von Priorisierung, der Möglichkeit der Rufdelegation und weiterer Mechanismen bspw. durch Einbindung von Servicekräften ein effizienter Nachrichtenfluss gewährleistet. Potenziell hinderliche Faktoren für die Akzeptanz sind zum einen, dass zu detailliertes Feedback an den Patienten Erwartungen wecken und so Druck auf die Pflegenden ausüben könnte, dem diese aufgrund der hohen Arbeitsbelastung nicht gerecht werden können. Zum anderen besteht ein Risiko, dass der Einsatz weiterer Technik zunächst als Mehraufwand wahrgenommen und abgelehnt wird. Diese Aspekte wurden bei der Entwicklung berücksichtigt.
