- KonferenzbeitragHuman-Machine Interaction in Care-Education(Mensch und Computer 2017 - Workshopband, 2017) Reichold, Johannes; Agrawal, Ankita; Thurlings, Marieke; Cohen, Iris; Weber-Fiori, Barbara; Rölle, Anita; Hassan, Muneeb; Dürr, Maximilian; Pfeil, Ulrike; Pape, Anna-Antonia; Grünert, Gerd; Schmidt, Artur; Pfeil, Markus; Fäßler, Victor; Jauch, Volker; Reiterer, Harald; Winter, Maik; Ertel, Wolfgang; Eberhardt, JörgThe research project ERTRAG, funded by the German Federal Ministry of Education and Research, aims to develop a virtual ergonomics trainer for nursing as well as elderly care education. The trainer supports apprentices conducting the care related motions in an ergonomically correct fashion, thereby helping to prevent work-related health problems such as dorsal pain. The user interface of the ERTRAG system for instruction and feedback adjusts to the individual preferences and needs, as well as to the current cognitive state of the user. This adaptive, highly customizable human-machine interaction fosters effective and long-lasting learning.
- KonferenzbeitragEin hybrider Ansatz zur Unterstützung kollaborativer Designtechniken(Mensch & Computer 2011: überMEDIEN|ÜBERmorgen, 2011) Geyer, Florian; Pfeil, Ulrike; Höchtl, Anita; Budzinski, Jochen; Reiterer, HaraldDieser Artikel stellt einen hybriden Ansatz zur Unterstützung kollaborativer Designtechniken vor. Die anhand der Designtechnik Affinity Diagramming beschriebenen Interaktionskonzepte werden aus einer Literaturrecherche und einer empirischen Studie abgeleitet. Diese Analyse zeigt, dass die Nutzung von Papierartefakten insbesondere in divergenten Phasen von Vorteil ist. Des Weiteren wird aufgezeigt, welche Auswirkung häufige Wechsel zwischen Arbeitsflächen in konvergenten Phasen haben können. Die auf Basis dieser Erkenntnisse entwickelten Interaktionskonzepte kombinieren Papierartefakte mit interaktiven Displays zur Unterstützung kreativer Arbeitsabläufe.
- KonferenzbeitragLearning Patient Transfers with Technology: A Qualitative Investigation of the Design Space(Mensch und Computer 2019 - Tagungsband, 2019) Dürr, Maximilian; Pfeil, Ulrike; Müller, Jens; Borowski, Marcel; Gröschel, Carla; Reiterer, HaraldNurses who care about patients with functional disabilities are frequently required to transfer a patient from one place to another. To prevent nurses from injuring themselves during patient transfers, many government-supported schools in Germany provide programs which teach how to conduct transfers based on the kinaesthetics care conception. However, the program is typically limited to merely three lectures. With the goal of promoting nurses' health behavior, we analyzed current practices in kinaesthetics education and explored how interactive technology can extend those practices. We interviewed nursing-care teachers (N = 5) and students (N = 27), and conducted four contextual inquiries during kinaesthetics course sessions. A qualitative analysis of the data revealed three themes. Based on these, we describe a set of implications to support the learning of kinaesthetics-based transfers by means of technology. We propose the use of the implications as initial design goals for user-centered design processes and exemplify their application by illustrating a concept for a tablet-based learning system.
- KonferenzbeitragLoci Spheres: A Mobile App Concept Based on the Method of Loci(Mensch und Computer 2017 - Tagungsband, 2017) Wieland, Jonathan; Müller, Jens; Pfeil, Ulrike; Reiterer, HaraldThe method of loci is a technique to memorize large quantities of information by associating the items to be learned with familiar places (loci). The effectiveness of the technique has been well established, but the initial creation of the loci can be a tedious task. With the aim of supporting flexible learning in situ, we introduce Loci Spheres, a novel concept which facilitates the creation of loci using mobile devices. We present three variants which support the technique to varying degrees: spatial loci (uses spatial input) and panning loci (uses panning) to define and navigate the loci, and no loci (baseline condition), where users have to create the loci within their imagination. In an in-the-wild study we investigated perceived system support, usage behavior, and effectiveness of the three variants. With this work we introduce a novel memorization tool which addresses the potential barrier involved in loci creation and provide a set of four design principles on how to leverage the technique with mobile devices in everyday situations.
- KonferenzbeitragA Qualitative Comparison Between Augmented and Virtual Reality Collaboration with Handheld Devices(Mensch und Computer 2019 - Tagungsband, 2019) Müller, Jens; Zagermann, Johannes; Wieland, Jonathan; Pfeil, Ulrike; Reiterer, HaraldHandheld Augmented Reality (AR) displays offer a see-through option to create the illusion of virtual objects being integrated into the viewer's physical environment. Some AR display technologies also allow for the deactivation of the see-through option, turning AR tablets into Virtual Reality (VR) devices that integrate the virtual objects into an exclusively virtual environment. Both display configurations are typically available on handheld devices, raising the question of their influence on users' experience during collaborative activities. In two experiments, we studied how the different display configurations influence user experience, workload, and team performance of co-located and distributed collaborators during a spatial referencing task. A mixed-methods approach revealed that participants' opinions were polarized towards the two display configurations, regardless of the spatial distribution of collaboration. Based on our findings, we identify critical aspects to be addressed in future research to better understand and support co-located and distributed collaboration using AR and VR displays.
