Prognose der Verkehrslage in der Region Hannover
Die primäre Anforderung der Verkehrsteilnehmer im Bereich des Straßenverkehrs ist die Kenntnis der aktuellen Verkehrslage. Diese basiert in der Regel auf der wirklich benötigten Reisezeit von sehr vielen Verkehrsteilnehmern, deren Daten häufig im Kontext von Routingdiensten abgegriffen werden.
Im Rahmen von Data4UrbanMobility wurden Werkzeuge entwickelt um eine ganglineinbasierte Prognose der Verkehrslage zu ermöglichen. Die folgende Abbildung zeigt eine Oberfläche auf der typische Ganglinienverläufe und Ausreißer visualisiert werden.

Die Prognose der Verkehrslage kann dann mittels einer Karte für den Endnutzer visualisert werden:

Erste Version der MIC-App bereitgestellt
Eine erste Version der MIC-App (Move in the City) konnte allen Partnerinnen und Partnern des Projekts und einer geschützten Nutzer*innengruppe der Öffentlichkeit zur Verfügung gestellt werden. Die mobile App MiC ist ein Instrument zur Datenerhebung.
Dabei verknüpft MiC – eine Entwicklung des Institute for Sustainable Urbanism ISU der TU Braunschweig und Projektionisten GmbH Hannover – das wachsende Bewusstsein und die Notwendigkeit für digitale Bürger*innenrechte mit den Potentialen mittels der Auswertung großer Datenmengen neue Formen der menschzentrierten Entwicklung von Stadt und Mobilität zu ermöglichen stellt eine Möglichkeit dar, sich aktiv als Bürgerwissenschaftlerin und Bürgerwissenschaftler an der Forschung und Entwicklung der Mobilität für alle in der Stadt der Zukunft zu beteiligen.
MiC erhebt – durch die Nutzerinnen und Nutzer gesteuert – Daten zu Strecken und Art der Fortbewegung. Diese Daten werden pseudonymisiert, so dass ein Rückschluss auf die jeweilige Person nicht mehr möglich ist. Wichtig ist die Vielzahl der Nutzerinnen und Nutzer – nicht die einzelne Bewegung. Die Stadt der Zukunft zeichnet sich aus durch den barrierearmen Zugang zu Mobilität und Erreichbarkeit für alle. Der holistische Ansatz der Forscherinnen und Forscher des Institute for Sustainable Urbanism ISU (TU Braunschweig) sowie der Projektbeteiligten betrachtet Stadt dabei auf verschiedenen Maßstabsebenen und bringt intelligente Planungen – wie z.B. die 5-Minuten Stadt –, Städtebau und innovative Technologien zusammen. Für ein umfassendes Verständnis individueller Mobilität und darauf aufbauende neue Methoden und Werkzeuge für integrierte Verkehrs- und Stadtplanung werden mittels der MiC-App uns umfangreiche und detaillierte Daten darüber geliefert, wie und auf welchem Wege wir uns in der Stadt fortbewegen.
Entwicklungsstand:
In der ersten Version ermöglicht das Stadtforschungstool MiC den Nutzer*innen durch eine einfach Handhabung das Starten und Beenden der „Tracking-Time“ (Bild 1). Wichtig ist, die Nutzer*innen entscheidet selber über den Zeitraum. Als erstes Ergebnis für die Nutzer*innen steht eine Zusammenfassung ihrer bisher aufgezeichneten Routen (Bild2). In den Einstellung (Bild 3) kann der Nutzer sich aktiv an Feedback beteiligen (Bild 4) sowie seinen Account und somit seiner zur Verfügung gestellten Daten löschen (Bild 5).

Erste Version der D4UM-App bereitgestellt
Eine erste Version der D4UM-App konnte allen Partnern des Projekts zur Verfügung gestellt werden. Die App stellt eine Möglichkeit dar, sich Fahrtauskünfte mit dem öffentlichen Personennahverkehr in Niedersachsen und Bremen (Datengrundlage: EFA – elektronische Fahrplanauskunft für Niedersachsen und Bremen) ausgeben zu lassen. Im Fokus stand hierbei, dass der Nutzer schnell und einfach an die für ihn wichtigen Informationen gelangen kann, um so seine Reise möglichst simpel planen zu können.
Folgende Funktionen dienen dabei in der ersten Version der schnellen Auskunft:
Abfahrten und Verbindungen
Über die Funktion Abfahrten lassen sich Abfahrtszeiten an einer bestimmten oder an nahegelegenen Haltestellen ermitteln. Unter Verbindungen können hingegen Fahrtvorschläge von einem Startpunkt (Adresse oder Haltestelle) zu einem Zielpunkt gesucht werden. Zeiten stehen dabei auch in Echtzeit zur Verfügung, sodass auch Verspätungen direkt von dem Nutzer erkannt werden können.

Karte
Über die Karte sind alle Haltestellen zu finden, sodass sich der Nutzer einen Überblick über die nähere Umgebung oder auch den Weg zur Haltestelle oder einem Ziel verschaffen kann.
Wird auf der Karte auf ein Haltestellensymbol oder den zugehörigen Haltestellennamen geklickt, öffnet sich der Abfahrtsmonitor zu dieser Haltestelle. Die nächsten Abfahrten können somit auch über diesen Weg aufgerufen werden.
Darüber hinaus kann sich der Nutzer auch den Verlauf seiner Fahrt anzeigen lassen.

Menü/Einstellungen
Weitere Funktionen und Einstellungen finden sich ergänzend im Menü der App.
Der Nutzer bekommt hier zum einen die Möglichkeit, dass erweiterte Einstellungen zu den Suchanfragen bei Verbindungen oder Abfahrten vorgenommen werden können, und zum anderen, dass er weitere Features verwenden kann. Darunter befindet sich zum Beispiel das Feedbackformular. Hierüber kann unkompliziert Kontakt mit den Entwicklern der D4UM-App per Mail aufgenommen werden. Icons ermöglichen es, dass ein Eindruck zu der App übermittelt werden kann. Ein weiteres Feld für Freitext bietet zudem Platz für individuelle Kritik und einer Meinung zu der App. So kann in Zukunft kundennah an der App weiterentwickelt und einfach auf Wünsche und Meinungen reagiert werden.

Quantifizierungen und Vorhersage von Auswirkungen von Veranstaltungen
Neue Data4UrbanMobility-Forschungsergebnisse ermöglichen es, die räumlichen Auswirkungen von Veranstaltungen zu quantifizieren und vorherzusagen. Dazu werden zusammenhängende, betroffene Straßenabschnitte in der Nähe von Veranstaltungen identifiziert. Auf dieser Grundlage kann dann die räumliche Auswirkung quantifiziert werden. Das Verfahren ist in der folgenden Grafik dargestellt.

Hier in Gelb markiert ist eine Veranstaltung, in Rot betroffene Straßenabschnitte und in Dunkelblau die gemessene Auswirkung. Weiterhin wurden Verfahren des Maschinellen Lernens angewandt, um diese Auswirkungen zu prognostizieren. Dabei konnte der Fehler gegenüber bestehenden state-of-the-art Ansätzen um bis zu 40% verringert werden.
D4UM – Plattform V1 fertiggestellt
Die erste Version der Data4UrbanMobility Plattform wurde fertiggestellt. Dazu wurde zunächst eine 3-Schichten Architektur der Plattform konzipiert und implementiert. Die Plattform bietet RESTfull Webservices für Mobilitätsapplikationen wie Dashboard-Anwendungen oder Apps an. Als erste Beispielanwendung wurde dazu eine interaktive Karte entwickelt, die die Auswirkungen von Veranstaltungen visualisiert. Ein Ausschnitt aus der Anwendung ist im folgenden Screenshot zu sehen.

Zu sehen sind 4 Veranstaltungen in Hannover. Die Farben entsprechen dabei unterschiedlichen Veranstaltungsarten (etwa Konzerte, Messen, Fußballspiele). Die Kreise visualisieren die räumlichen Auswirkungen, die diese Veranstaltungen auf den Verkehr hatten.
Umfangreicher Anforderungskatalog
Die Data4UrbanMobility Anforderungsanalyse umfasst die Erfassung der Anforderungen der Anwendungspartner Region Hannover (RH) und Wolfsburg AG (WAG), sowie der nicht-funktionalen Anforderungen. Aus den Anforderungen der AnwendungspartnerInnen (RH und WAG), die von MOMA erhoben wurden, sind von L3S Forschungsfragen für die Datenanalyse abgeleitet worden, die sich speziell auf die Informationsbedürfnisse der AnwenderInnen beziehen und im weiteren Projektverlauf adressiert werden.
Die aktuelle Forschungsfragen adressieren insbesondere:
- Automatische Verifikation von Verkehrswarnmeldungen und Prognose von deren Auswirkungen.
- Identifikation von Veranstaltungen und Prognose verkehrsrelevanter Auswirkungen.
- Korrelation von IV-Reiseflussdaten, EFA-Querylogs, Warnmeldungen und Twitterfeeds.
- Bestimmung von optimalen Reisezeitpunkte.
Wachsende Datensammlung
Das ISU hat einen umfassende Datenmatrix mit potentiellen Quellen für mobilitätsrelevante Daten erstellt. Das von L3S entwickelte Data4UrbanMobility Datenmodell beschreibt alle projektrelevanten Daten und setzt diese in Verbindung um die Daten sowohl für die Analyse als auch für die Anwendungen und Apps einheitlich zur Verfügung zu stellen. Die ausgewählten Datenquellen sind von L3S in das Data4UrbanMobility Datenmodell überführt. Einige der Datenquellen wie EFA-logs, und IV-Daten sind dabei auf deren Qualität geprüft worden.
Um die Datenintegration zu ermöglichen sind Werkzeuge zur Extraktion der relevanten Daten aus Mobilitätsrelevanten Datenquellen entwickelt worden:
- Straßen- und Graphextraktion aus OpenStreetMap
- EFA-Anfragen Bulkloader für die Extraktion der ÖPNV Anfragen aus EFA Logs
- Integration von Daten aus dem Zentralen Haltestellen Verzeichnis (ZHV) inklusive Verknüpfung der Daten mit den EFA-Anfragen
Die aktuelle Datensammlung (Stand: 12 Dezember 2017) umfasst:
EFA-Logs: 17 Mio. Suchanfragen
IV-Daten: 174 Tsd. Straßen, alle 15 Minuten
GTFS-Daten: 90 Tsd. Haltestellen, 2,6 Tsd. Routen
Wetter: Radolan Regenraster
Twitter: 2,5 Mio. Tweets ab Juni 2017
OSM: 440 Tsd. Straßen
Events: 21 Tsd. Veranstaltungen (14.08.2016-17.07.2018)
Warnmeldungen: 13 Tsd. Warnmeldungen (ab 06.2017)
Visualisierungen der ÖPNV Informationen
Zur intuitiven Analyse von mobilitätsrelevanten Informationen, insbesondere von ÖPNV Informationen, wurde von den PROJEKTIONISTEN (PROJ) eine Dashboard-Webapplikation konzipiert. Erste Prototypen visualisieren Anfragen an das regionale Fahrplanauskunftsystem EFA (www.efa.de) und dienen als Ausgangsbasis für explorative Analysen und die Implementierung der produktiven Version des Dashboards. Im Folgenden ist eine im Dashboard integrierte Visualisierung der häufigsten Start- und Ziel-punkte zu sehen.

Analysen der EFA-Logs
Als erste Forschungsfrage wird aktuell die Analyse der Auswirkungen der Veranstaltungen auf dem ÖPNV mit Methoden des Maschinellen Lernens analysiert. Hierzu wurden in explorativen Datenanalysen der Einfluss von großen Veranstaltungen wie z.B. Fussballspielen und mittelgroßen Veranstaltungen, etwa Konzerte, auf Anfragen an den ÖPNV betrachtet. Als Grundlage für umfassende Analysen wurden mit Hilfe visueller Methoden exemplarisch Korrelation zwischen ÖPNV-Nachfrage und Veranstaltungszeiträumen detektiert.
Dabei zeichnen sich z.B. für Hannovers Innenstadt klare, sternförmige Muster ab, die zentrale Mobilitätsknoten identifizieren.

Das Bild stellt die Luftlinie zwischen Start- und Ziel-Ort der Anfragen dar. Dabei entsprechen dunklere Farben häufigeren Strecken. Hier werden deutlich Hannover Hauptbahnhof und Hannover Kröpcke (die zentrale U-Bahn Station) als Mobilitätsknoten identifiziert.
Analysen der Nachfrage für einzelne Stationen lassen wochentagspezifische Muster erkennen.

Hier dargestellt sind die durchschnittliche Anzahl der Anfragen mit der Ziel-Haltestelle “Hannover Stadionbrücke”. Zu erkennen sind vor allem Unterschiede zwischen Werktagen und dem Wochenende.
Auch der Einfluss von Veranstaltungen kann mit Hilfe der Anfragen visualisiert werden:

Dargestellt sind die Anzahl der Anfragen mit Ziel “Hannover Stadionbrücke” für Mittwoch, den 26.04.2017 (Orange) sowie die durchschnittlichen Anzahl von Anfragen, die mittwochs mit gleichem Ziel gestellt wird (Blau).
An diesem Tag fand in einer nahe gelegenen Konzerthalle ein Konzert statt, das um 20 Uhr begann. Die signifikante Abweichung zwischen 17 und 19 Uhr wurde sehr wahrscheinlich von den anreisenden Gästen verursacht wurde. Dies illustriert, dass Anfragen an den ÖPNV eine wertvolle Informationsquelle sein können, um Prognosen über die Auswirkung von Veranstaltungen auf Mobilität zu erstellen.

Circular RNAs increase during vascular cell differentiation and are biomarkers for vascular disease. Northoff, Bernd H; Herbst, Andreas; Wenk, Catharina; Weindl, Lena; Gäbel, Gabor; Brezski, Andre; Zarnack, Kathi; Küpper, Alina; Dimmeler, Stefanie; Moretti, Alessandra; Laugwitz, Karl-Ludwig; Engelhardt, Stefan; Maegdefessel, Lars; Boon, Reinier A; Doppler, Stefanie; Dreßen, Martina; Lahm, Harald; Lange, Rüdiger; Krane, Markus; Krohn, Knut; Kohlmaier, Alexander; Holdt, Lesca M; Teupser, Daniel (2025). 121(3) 405–423.
AIMS: The role of circular RNAs (circRNAs) and their regulation in health and disease are poorly understood. Here, we systematically investigated the temporally resolved transcriptomic expression of circRNAs during differentiation of human induced pluripotent stem cells (iPSCs) into vascular endothelial cells (ECs) and smooth muscle cells (SMCs) and explored their potential as biomarkers for human vascular disease. METHODS AND RESULTS: Using high-throughput RNA sequencing and a de novo circRNA detection pipeline, we quantified the daily levels of 31 369 circRNAs in a 2-week differentiation trajectory from human stem cells to proliferating mesoderm progenitors to quiescent, differentiated EC and SMC. We detected a significant global increase in RNA circularization, with 397 and 214 circRNAs up-regulated greater than two-fold (adjusted P < 0.05) in mature EC and SMC, compared with undifferentiated progenitor cells. This global increase in circRNAs was associated with up-regulation of host genes and their promoters and a parallel down-regulation of splicing factors. Underlying this switch, the proliferation-regulating transcription factor MYC decreased as vascular cells matured, and inhibition of MYC led to down-regulation of splicing factors such as SRSF1 and SRSF2 and changes in vascular circRNA levels. Examining the identified circRNAs in arterial tissue samples and in peripheral blood mononuclear cells (PBMCs) from patients, we found that circRNA levels decreased in atherosclerotic disease, in contrast to their increase during iPSC maturation into EC and SMC. Using machine learning, we determined that a set of circRNAs derived from COL4A1, COL4A2, HSPG2, and YPEL2 discriminated atherosclerotic from healthy tissue with an area under the receiver operating characteristic curve (AUC) of 0.79. circRNAs from HSPG2 and YPEL2 in blood PBMC samples detected atherosclerosis with an AUC of 0.73. CONCLUSION: Time-resolved transcriptional profiling of linear and circRNA species revealed that circRNAs provide granular molecular information for disease profiling. The identified circRNAs may serve as blood biomarkers for atherosclerotic vascular disease.
Continuous value shaping: A boundary concept for innovating service innovation approaches. Böhmann, Tilo; Roth, Angela; Satzger, Gerhard; Benz, Carina; Beverungen, Daniel; Boes, Andreas; Breidbach, Christoph; Gersch, Martin; Gudergan, Gerhard; Hogreve, Jens; Kurtz, Christian; Langes, Barbara; Leimeister, Jan Marco Leimeister; Lewandowski, Tom; Meiren, Thomas; Nägele, Rainer; Paluch, Stefanie; Peters, Christoph; Poeppelbuss, Jens; Robra‑Bissantz, Susanne; Schultz, Carsten; Schumann, Jan H.; Wirtz, Jochen; Wünderlich, Nancy V. (2025). 35(27) 20.
Technological advancements and evolving value orientations reshape future value creation and pose new requirements for service innovation. While a variety of disciplines are developing new approaches to drive service innovation, this is primarily done in isolation and generates only fragmented solutions. Sociological theory has proposed “boundary objects” as an effective umbrella for communication and cooperation among communities. Therefore, we introduce continuous value shaping (CVS) as a boundary object describing service innovation approaches along five principles. We reflect on this concept through the different disciplinary lenses of researchers in service marketing, information systems, service engineering, sociology of work, and innovation management. These perspectives highlight how the CVS principles already connect to discourses within the individual disciplines. However, the CVS concept will not only provide an umbrella to embrace existing activities in different academic disciplines. It also assists to identify research themes that will benefit from uniting the power of these disciplines, and it can serve as an integrating framework to conceptualize complex service innovation approaches. Thus, the CVS concept should guide both researchers and practitioners to develop and implement novel innovation and transformation efforts—in and across organizations.
Erfolgreich gescheitert: Schlussbilanz zum Koalitionsvertrag der Ampel 2021–2025. Technical Report (03/2025), Vehrkamp, Robert; Matthieß, Theres (2025).
Anstatt mehr Koalition zu wagen, hat die Ampel sich in ihrer zweiten Halbzeit für noch mehr Streit und den Bruch entschieden. Das prägt auch ihre Schlussbilanz: Nur etwas mehr als die Hälfte (52 Prozent) ihrer Regierungsvorhaben wurden umgesetzt. Dennoch war die Ampel mehr als eine gescheiterte Streitkoalition. In ihren drei Regierungsjahren hat sie absolut gesehen mehr Vorhaben umgesetzt als ihre beiden Vorgängerregierungen in jeweils vier Jahren. Die Gesamtnote lautet deshalb: Erfolgreich gescheitert.

Architecting Intelligent Decentralized Data Systems to Enable Analytics with Entropy-Aware Governance, Quantum Readiness and LLM-Driven Federation. Schnabel, Ralf (2025). 17(1/2) 17–23.
Enterprises pursuing AI-driven transformation face a critical tradeoff: centralized consistency vs. decentralized scalability. The "Data Platform Unification Paradox" captures this dilemma. Building on our prior NLPI 2025 paper, this extended version integrates technical depth, mathematical models, and concrete architectures, especially for integrating Data Mesh with Quantum Databases and LLM Agents. A federated architecture is proposed using graph-theoretic models and entropy-based data valuation. We introduce a formal structure to evaluate platform complexity and propose intelligent agent-based governance models to operationalize data sharing across domains. This work aims to move beyond conceptual frameworks by proposing actionable blueprints for next-generation, intelligent data ecosystems.
Selective directional enhancement in Gold/Perovskite quantum dot metasurfaces. Adnan, Mohammad; Sarkar, Swagato; Aftenieva, Olha; Brunner, Julius; Fery, Andreas; Vaynzof, Yana; König, Tobias A.F (2025). 13(13) 2403397-.
Abstract Controlling directional radiation with minimal loss and fabrication effort through scalable methods is essential for integrating metasurfaces into photonic devices. Existing strategies enable tuning radiation properties by altering optical parameters of subwavelength dielectric gratings. Herein, a simple method is demonstrated to control the radiation direction of perovskite quantum dot (QD) metasurfaces through the addition of thin gold layers. This approach utilizes hybrid plasmonic modes and defect-free, template-assisted self-assembly techniques for low-loss, large-area production. This colloidal method allows precise control over nanostructure formation, ensuring reproducibility and enhanced optical properties. A 4.6-fold enhancement of the radiation toward the substrate and a 4.4-fold enhancement toward the cover region is achieved by evaporating a thin gold film with an optimal periodicity of 500 nm. Notably, the insertion of a metal layer allows the cover mode to exhibit enhancements that exceed typical expectations for plasmonic metasurfaces. This design is supported by plasmonic lattice theory and validated by electromagnetic modeling, allowing the gamma point to be customized to enhance emission in specific directions and media directly. This rational design strategy enhances the functionality of plasmonic perovskite-based metasurfaces for photonic on-chip applications, including nonlinear light-emitting devices and directional light sources.
How a Clinical Decision Support System Changed the Diagnosis Process: Insights from an Experimental Mixed-Method Study in a Full-Scale Anesthesiology Simulation. Wolf, Sara; Grundgeiger, Tobias; Zähringer, Raphael; Shishkova, Lora; Maas, Franzisca; Dilling, Christina; Happel, Oliver in CHI ’25 (2025).
Recent advancements in artificial intelligence have sparked discussions on how clinical decision-making can be supported. New clinical decision support systems (CDSSs) have been developed and evaluated through workshops and interviews. However, limited research exists on how CDSSs affect decision-making as it unfolds, particularly in settings such as acute care, where decisions are made collaboratively under time pressure and uncertainty. Using a mixed-method study, we explored the impact of a CDSS on decision-making in anesthetic teams during simulated operating room crises. Fourteen anesthetic teams participated in high-fidelity simulations, half using a CDSS prototype for comparative analysis. Qualitative findings from conversation analysis and quantitative results on decision-making efficiency and workload revealed that the CDSS changed team structure, communication, and diagnostic processes. It homogenized decision-making, empowered nursing staff, and introduced friction between analytical and intuitive thinking. We discuss whether these changes are beneficial or detrimental and offer insights to guide future CDSS design.
Observation of the axion quasiparticle in 2D MnBi\($_\mathbf2$\)Te\($_\mathbf4$\). Qiu, Jian-Xiang; Ghosh, Barun; Schütte-Engel, Jan; Qian, Tiema; Smith, Michael; Yao, Yueh-Ting; Ahn, Junyeong; Liu, Yu-Fei; Gao, Anyuan; Tzschaschel, Christian; Li, Houchen; Petrides, Ioannis; Bérubé, Damien; Dinh, Thao; Huang, Tianye; Liebman, Olivia; Been, Emily M.; Blawat, Joanna M.; Watanabe, Kenji; Taniguchi, Takashi; Fong, Kin Chung; Lin, Hsin; Orth, Peter P.; Narang, Prineha; Felser, Claudia; Chang, Tay-Rong; McDonald, Ross; McQueeney, Robert J.; Bansil, Arun; Martin, Ivar; Ni, Ni; Ma, Qiong; Marsh, David J. E.; Vishwanath, Ashvin; Xu, Su-Yang (2025). 641(8061) 62–69.
The axion is a hypothetical fundamental particle that is conjectured to correspond to the coherent oscillation of the \($\theta$\) field in quantum chromodynamics1,2. Its existence would solve multiple fundamental questions, including the strong CP problem of quantum chromodynamics and dark matter, but the axion has never been detected. Electrodynamics of condensed-matter systems can also give rise to a similar \($\theta$\), so far studied as a static, quantized value to characterize the topology of materials3--5. Coherent oscillation of \($\theta$\) in condensed matter has been proposed to lead to physics directly analogous to the high-energy axion particle---the dynamical axion quasiparticle (DAQ)6--23. Here we report the observation of the DAQ in MnBi2Te4. By combining a two-dimensional electronic device with ultrafast pump--probe optics, we observe a coherent oscillation of \($\theta$\) at about 44thinspacegigahertz, which is uniquely induced by its out-of-phase antiferromagnetic magnon. This represents direct evidence for the presence of the DAQ, which in two-dimensional MnBi2Te4 is found to arise from the magnon-induced coherent modulation of the Berry curvature. The DAQ also has implications in light--matter interaction and coherent antiferromagnetic spintronics24, as it might lead to axion polaritons and electric control of ultrafast spin polarization6,15--20. Finally, the DAQ could be used to detect axion particles21--23. We estimate the detection frequency range and sensitivity in the millielectronvolt regime, which has so far been poorly explored.
Optical whispering-gallery mode as a fingerprint of magnetic ordering in van der Waals layered CrSBr. Pang, Chi; Li, Rang; Long, Fangchao; Li, Yi; Tang, Min; Soll, Aljoscha; Mosina, Kseniia; Sofer, Zdenek; Jamshidi, Kambiz; Chen, Feng; Vaynzof, Yana; Helm, Manfred; Zhou, Shengqiang; Ma, Libo (2025). n/a(n/a) 2505275-.
Abstract An ultra-sensitive nanoscale magnetism sensing of van der Waals layered CrSBr is demonstrated by employing optical whispering-gallery-mode (WGM) resonances in a self-rolled-up microcavity. CrSBr nanoflakes with and without intercalation are probed by monitoring the WGM resonant modes shift as a function of magnetic field intensity and temperature, revealing the presence of ferromagnetic (FM) and antiferromagnetic (AFM) order. The minimum detectable amount of CrSBr nanoflakes reaches the femtogram scale, and the detection limit is as low as 1.25 ? 10?16 emu. This study demonstrates a promising application of WGM microcavities for highly sensitive magnetism detection with reduced system complexity, establishing a novel bridge between materials? optical and magnetic properties.

Participation User Experience: A Call to Better Manage the Most Important Resource in User-Centered Design. Heinisch, Melina Joline; Wolf, Sara; Maas, Franzisca; Huber, Stephan in CHI EA ’25 (2025).
Participating users are the foundation of user-centered design. However, there is a limited understanding of their motivation, engagement, and experience participating in research. In this work, we propose the concept of Participation User Experience (PUX), which addresses participants’ experiences in user-centered design. To set a scope for PUX, we conducted a reflexive thematic analysis on workshop data involving 20 experienced user-centered design practitioners and researchers. The analysis yielded five themes, making explicit aspects of PUX that have been implicitly considered and how their consideration could be improved. Great potential lies in addressing intrinsic motivations over extrinsic incentives and developing more structured approaches to planning and measuring PUX to mitigate various sources of bias related to incentives or Experimenter Effects. We contribute to a first understanding of PUX, point to persisting research gaps, and present practical implications for improving participants’ experiences in user-centered design.

Segen Interaktiv: die Interdisziplinäre Entwicklung Eines Außerschulischen Lernortes zu Interreligiösen Segensräumen. Nord, Ilona; Wolf, Sara; Luthe, Simon; Hurtienne, Jörn; Schleier, Leon A. Füting-Lippert, M. Eisenmann, S. Grafe, H.-S. Siller, T. Trefzger (eds.) (2025). 121–139.
Religionskulturen nehmen zunehmend Designformate von Digital Religion an. Dabei zeigt sich als religionspädagogisch nahezu unerforscht die didaktisch reflektierte User Experience und das Design von digitalen Lehr- und Lernszenarien. AP6 geht aus der Perspektive der interdisziplinären Zusammenarbeit von Human--Computer Interaction und Ev. Religionspädagogik davon aus, dass Religionen und mit ihnen Glaubenspraxen am gesellschaftlichen Wandel zu einer Kultur der Digitalität teilhaben. Es wird auf vorangehende Studien aufgebaut, die zeigen, dass die Erwartung von Lehrpersonen, guten Unterricht mit digitalen Medien gestalten zu können, von positiven Vorerfahrungen mit diesen abhängt. Das Projekt greift hierfür exemplarisch die innerhalb von digitalen Kommunikationen verbreitete religiöse Urgeste des Segens und Segnens auf. In einem iterativen Prozess entstanden interaktive Exponate, sogenannte Blessing Machines. Sie wurden entlang psychologischer Bedürfnisse mit dem Ziel gestaltet, für Schüler:innen und ihre Lehrpersonen religionserschließende Erfahrungen mit digitalem Lernen zu ermöglichen. 200 Personen testeten die dreizehn Blessing Machines (Schulklasse, Konfirmandengruppen) in the wild. Religionslehrpersonen wurden hierbei von der „Logistik`` des Einsatzes digitaler Medien im Unterricht entlastet. Der außerschulische Lernort erfüllte die wichtige Funktion, Schüler:innen und Lehrpersonen gelingende Erfahrungen mit Digital Religion zu ermöglichen. Die Gestaltung der Blessing Machines hat sich als wirksam herausgestellt, besonders Aspekte von Autonomie, Stimulation, Verbundenheit, Gemeinschaft und Provokation wurden positiv hervorgehoben.

Wax Arts With Honeybees – Taking First Steps Toward Multispecies Co-Creation. Huber, Stephan; Friedenberger, Tamara; Borlinghaus, Parzival; Wolf, Sara in TEI ’25 (2025).
Centuries of beekeeping restricted the honeybees’ role to a producer of raw material, such as honey or wax, which is then harvested and processed, resulting in all artistic value being added by humans. In this project, we regard honeybees (Apis mellifera) as co-creators and explore the joint creations of our two species. During our first season, we scoped the co-creative space over the course of four months. We present image material of sculptures that exceed bees’ natural building behavior and contribute preliminary insights on artifacts originating from human-bee co-creation. We reflect on how human-introduced wax shapes made the bees deviate from their regular comb forms and discuss future paths of multi-species co-creation, temporality, material as well as ethical aspects. Our preliminary insights raise questions to be developed in discussions with the TEI community and answered in future work during the upcoming bee seasons.

Large Language Models: The best linguistic theory, a wrong linguistic theory, or no theory at all?. Müller, Stefan (2025). 44(1)
This paper discusses the claim that Large Language Models (LLMs) are the best linguistic theory we currently have. It discusses claims that LLMs are wrong linguistic theories and concludes that they are not linguistic theories at all. It is pointed out that Chomsky’s claims about innateness, about transformations as underlying mechanisms of the language faculty and about plausible representations of linguistic knowledge have been known to be flawed for quite some time by now and that we would not have needed LLMs for this. Chomsky’s theories are not refuted by LLMs in their current form since LLMs are different in many aspects from human brains. However, the tremendous success of LLMs in terms of applications makes it more plausible to linguists and laymen that the innateness claims are wrong. It is argued that the use of LLMs is probably limited when it comes to typological work and cross-linguistic generalizations. These require work in theoretical linguistics.

Chirality meets topology: building quantum bridges to catalysis. Wu, Xizheng; Wang, Xia; Felser, Claudia (2025).
Topological materials, characterized by their symmetry-protected electronic properties, offer transformative opportunities to integrate solid-state topology and catalysis. When coupled with chirality, novel classes of chiral material systems emerge, including topological chiral materials and magnetic chiral materials, distinguished by their unique chiral-related phenomena. Investigating the role of structural and electronic chirality on chiral catalytic processes holds significant promise for designing advanced chiral catalysts. This review provides a comprehensive overview of intrinsic chiral materials with chiral space groups, accompanied by an in-depth analysis of their electronic chirality, including chiral spin angular momentum, chiral orbital angular momentum, chiral charge density waves, and chiral Weyl points. Moreover, we discuss various tuning knobs that induce chiral responses in topological materials. By offering fundamental insights into the interplay between chiral quantum phenomena and chiral catalytic efficiency, this review bridges chemistry and physics, offering strategies to optimize emerging chiral catalytic systems, such as spin-dependent catalysis and asymmetric synthesis.

Size Doesn’t Matter? Down-Scaling a Data Physicalization Does Not Measurably Change Viewers’ Mediated Social Interactions. Friedenberger, Tamara; Hurtienne, Jörn in TEI ’25 (2025).
Data physicalizations are physical artifacts that represent data across sensory modalities. They are frequently used in informal learning environments, such as museums, which are inherently social spaces. Research on the design choices for data physicalizations and their effects in social contexts is sparse. Previous work examining the size of data physicalizations shows a tendency to favor larger designs to increase artefact-mediated social interactions among viewers (social engagement), but the empirical evidence remains inconclusive. To address this, we empirically investigated the effect of data physicalization size on social engagement and user experience. In this laboratory study, the social engagement between two viewers freely interacting with a data physicalization is analyzed across two sizes. The results do not indicate a clear advantage of a larger design for increasing social engagement. Thus, investing additional effort and material resources in making a physicalization larger would compromise sustainability for no measurable change in social engagement.
Resound: A Moment of Reflection in a Techno-Spiritual RtD Inquiry. Claisse, Caroline; Chatting, David; Wolf, Sara; Morris, Ben; Durrant, Abigail C in TEI ’25 (2025).
We present 'Resound', a Research through Design inquiry into alternative techno-spiritual practices of a UK Buddhist community, informed by a first-person and participatory approach with the members. In this pictorial we portray a moment of reflection as we consolidate our design work towards deployment with the community. We introduce the Resound Sphere, a materialisation of our learning and speculations to date, designed as a research product to empirically explore alternatives for how tangible interaction could mediate religious/spiritual practices. We contribute with the framing of a design space, the presentation of our design approach and artefact response to this design space.

Efficient Algorithms for Isogeny Computation on Hyperelliptic Curves: Their Applications in Post-Quantum Cryptography. Baraka, Mohammed El; Ezzouak, Siham in LNCS, N. Meghanathan (ed.) (2025). (Vol. 17) 93–112.
We present efficient algorithms for computing isogenies between hyperelliptic curves, leveraging higher genus curves to enhance cryptographic protocols in the post-quantum context. Our algorithms reduce the computational complexity of isogeny computations from O(g4) to O(g3) operations for genus 2 curves, achieving significant efficiency gains over traditional elliptic curve methods. Detailed pseudocode and comprehensive complexity analyses demonstrate these improvements both theoretically and empirically. Additionally, we provide a thorough security analysis, including proofs of resistance to quantum attacks such as Shor's and Grover's algorithms. Our findings establish hyperelliptic isogeny-based cryptography as a promising candidate for secure and efficient post-quantum cryptographic systems.

(Un)designing AI for Mental and Spiritual Wellbeing. Smith, C. Estelle; Bezabih, Alemitu; Freed, Diana; Halperin, Brett A.; Wolf, Sara; Claisse, Caroline; Li, Jingjin; Hoefer, Michael; Rifat, Mohammad Rashidujjaman in CSCW Companion ’24 (2024). 117–120.
With rapid advances in Artificial Intelligence (AI) impacting human health and wellbeing, scholarly discourse should focus equally on the prospective opportunities and harms of Human-AI Interaction (HAI) in Computer-Supported Collaborative Work and Social Computing (CSCW). This panel invites critical interdisciplinary discussion around the (un)designing of AI by asking: how, when, where, and why should AI (not) be involved in sociotechnical systems for mental and spiritual health and wellbeing? Motivated by functional, technical, and ethical concerns, the panel aims to ensure that: (1) progress in HAI for mental and spiritual health is informed by expertise from the respective clinical disciplines; (2) ethical and responsible design principles lie at the core of research motivations and methodologies; and (3) AI hype can be tempered by caution given its impacts on marginalized and stigmatized groups. A panel of respected experts in mental health, spiritual care, and AI will discuss CSCW topics regarding HAI in contexts of clinical practice (e.g., electronic health records, patient portals, decision-making and referral systems, technology-supported interactions during bedside care or clinical appointments) as well as social contexts beyond the clinic (e.g., social apps, online health communities and social media, and computer-mediated communication in spiritual/religious groups).
Navigating Intersections of Religion/Spirituality and Human-Computer Interaction. Markum, Robert B.; Maas, Franzisca; Wolf, Sara; Halperin, Brett A.; Claisse, Caroline; Buie, Elizabeth in NordiCHI ’24 Adjunct (2024).
Religion and spirituality (R/S) are an important part of many people’s lives, and while HCI is increasingly engaged in research and design in specific R/S contexts, there are many cases where researchers or designers encounter R/S outside of such contexts. In this workshop, we seek to bring together HCI researchers and designers across all research areas and with varying levels of experience with R/S to discuss encounters with R/S in their work, either intentional or not, and to develop principles and strategies to guide HCI research and design that intersects with R/S. Through this workshop, we also seek to further establish a network of scholars who can provide each other support in navigating R/S-related challenges and opportunities in their work and can participate in publication-oriented collaborations that consider the intersection of R/S and HCI.
Sensing Heritage: Exploring Creative Approaches for Capturing, Experiencing and Safeguarding the Sensorial Aspects of Cultural Heritage.

Whilst there is increasing work investigating the role of digital documentation, interpretation, and augmentation of cultural heritage, such interventions have largely focused on visual and sometimes auditory modalities, neglecting the full spectrum of human senses. With this workshop we seek to bring together an interdisciplinary group of researchers, designers, practitioners and community members to explore creative approaches for documenting and experiencing cultural heritage’s rich sensory dimensions extending beyond visual-based approaches to encompass sound, smell, taste, and touch. The workshop directly aligns with the conference’s exploration of "Why Design?" by utilising design as a powerful, empathetic, and participatory tool for safeguarding cultural heritage. Our goal is to extend our understanding of concepts, methods and technologies for capturing and experiencing sensory heritage, advocating for a holistic approach that celebrates and communicates the profound sensory diversity of human cultures, inspiring a shift in how we document, interpret and share cultural heritage.
Making Alternatives Through Design for Mediated Spiritual Practice. Claisse, Caroline; Chatting, David; Wolf, Sara; Morris, Ben; Durrant, Abigail C in HttF ’24 (2024).
The COVID-19 pandemic has intensified our dependence on screen-based devices, re-shaping how we connect with one another. Motivated by a yearning for alternative and post-pandemic religious and spiritual (R/S) practice, we pursue a Research-through-Design (RtD) project, Resound, exploring mediated technospiritual connections with a UK-based Buddhist community. This pictorial depicts the complexity of (i) designing with spiritual-corporeal selves engaged in community-centred and ritualistic practices; (ii) and tangible artefacts and sonic environments being made, configured and practiced with. We reflect on this ongoing material engagement as making tangible alternatives through techno-spiritual practice.
Mediating the Sacred: Configuring a Design Space for Religious and Spiritual Tangible Interactive Artifacts. Markum, Robert B.; Wolf, Sara; Claisse, Caroline; Hoefer, Michael in TEI ’24 (2024).
Tangible artifacts and embodied experiences are central to religious and spiritual (R/S) practices, and many HCI researchers and interaction designers highlight the importance of materiality and physicality in design. In this review paper, we bring these perspectives together and examine 44 examples of R/S tangible interactive artifacts (TIAs) from academia, art, industry, and R/S communities to understand their specifics and guide future HCI research and design. We analyze these artifacts and map out a design space for R/S TIAs by matching identified characteristics of R/S TIAs with a framework from the study of material religion. The descriptive and generative R/S TIA Design Space covers insights into bodies, things, places, practices, and backgrounds. This paper offers a novel contribution to HCI research on the value and importance of tangibility and embodiment in technology-mediated practices in R/S contexts and serves as a source for future R/S TIA creation and research.

Factors associated with high and low mental well-being in Spanish university students. Navarra-Ventura, Guillem; Riera-Serra, Pau; Roca, Miquel; Gili, Margalida; García-Toro, Mauro; Vilagut, Gemma; Alayo, Itxaso; Ballester, Laura; Blasco, Maria Jesús; Castellví, Pere; Colom, Joan; Casajuana, Cristina; Gabilondo, Andrea; Lagares, Carolina; Almenara, José; Miranda-Mendizabal, Andrea; Mortier, Philippe; Piqueras, José Antonio; Soto-Sanz, Victoria; Alonso, Jordi; study group, UNIVERSAL (2024). 356 424–435.
BACKGROUND: Previous studies conducted in various nationally representative samples of the general population show that positive mental health is related to social prosperity. However, specific studies in university populations are scarce. In this study, we set out to explore factors associated with mental well-being (MWB) in a representative sample of first-year university students in Spain. METHODS: MWB was assessed with the short version of the Warwick-Edinburgh Mental Well-Being Scale. Multinomial logistic regressions were performed to explore the association between different blocks of factors, including relational, adversity, stress, lifestyle, spiritual, health, and self-perceived health variables with high and low MWB, controlling for sociodemographic and university-related variables. RESULTS: Data from 2082 students (18.6 ± 1.2 years; 56.6 % females) were analysed. Being male, being born in a foreign country, "high" self-perceived support, and "high" self-perceived mental health increased the odds of high MWB. Growing up in the suburbs, stressful experiences, and anxiety disorders reduced the odds of high MWB. Mood and anxiety disorders increased the odds of low MWB. "Middle" self-perceived support, sleeping ≥8 h per day, and "high" self-perceived mental health reduced the odds of low MWB. LIMITATIONS: The cross-sectional design precludes establishing causal relationships. Data were collected in the 2014-15 academic year using self-reported online surveys. CONCLUSION: The factors associated with high and low MWB do not always mirror each other, so specific plans are needed to successfully address each of the two poles. Interventions and policies targeting these factors for health promotion and disease prevention would improve the MWB of university students.
Depression and lifestyle among university students: A one-year follow-up study. Roldán-Espínola, Lorenzo; Riera-Serra, Pau; Roca, Miquel; García-Toro, Mauro; Coronado-Simsic, Victoria; Castro, Adoración; Navarra-Ventura, Guillem; Vilagut, Gemma; Alayo, Itxaso; Ballester, Laura; Blasco, María Jesús; Almenara, José; Cebrià, Ana Isabel; Echeburúa, Enrique; Gabilondo, Andrea; Lagares, Carolina; Piqueras, José Antonio; Soto-Sanz, Victoria; Mortier, Philippe; Kessler, Ronald C.; Alonso, Jordi; Forteza-Rey, Inés; Gili, Margalida (2024). 38(3) 100250.
Background and objectives University stage is a risk period for development of mental disorders and major depression disorder (MDD) is one of the most prevalent disorders. There is increasing evidence about the influence of lifestyle factors on depression onset and maintenance, nevertheless there is a great heterogeneity between analyzed lifestyle factors and few longitudinal studies has been carried out. The current study aims to longitudinally assess the influence of lifestyle on MDD courses among first-year university students. Methods First-onset and persistence of MDD and lifestyle trajectories are measured using baseline and 12-months follow-up online surveys. Multivariate logistic regression analyses were performed to study longitudinal risk/protective associations between lifestyle factors and MDD. Results 1,292 participants were included. Mean age of included participants at baseline was 18.5 (SD= 1.16) and 75.7 % were female. First-onset and persistence of MDD at T2 were 10.3 % and 38.9 % respectively. Maintenance of healthy sleep (Adjusted Odds Ratio (aOR) = 0.26; 95 % CI =0.12–0.58) and physical activity (aOR = 0.24; 95 % CI = 0.10–0.58) were protectively associated against MDD first-onset. Adoption of healthy levels of social support showed a protective effect against MDD persistence (aOR = 0.17; 95 % CI = 0.07–0.44). Conclusions Lifestyle should be considered in order to improve depression prevention strategies among university students. Sleep, physical activity, and social support seem to have a crucial role in the onset and persistence of depression among this population.

Still Not a Lot of Research? Re-Examining HCI Research on Religion and Spirituality. Wolf, Sara; Friedrich, Paula; Hurtienne, Jörn in CHI EA ’24 (2024).
A decade after Buie and Blythe’s review "Spirituality: There’s an App for That! (But Not a Lot of Research)", this sequel assesses the evolving landscape of Human-Computer Interaction (HCI) research on religion and spirituality. While the enduring importance of religion and spirituality for humanity and its influence on technology use remains, the last decade has seen transformative shifts catalysed by technological advances and the global impact of the COVID-19 pandemic. This paper explores whether and how HCI research on religion and spirituality has also changed. Providing a snapshot of the current research, we document and reflect on changes in the lines of research with a shift towards community, an increased consideration of religion and spirituality in related areas such as health, education, and society, and the broadening of challenges for HCI research on religion and spirituality.
Ingeborg Beling and the time memory in honeybees: almost one hundred years of research. Beer, Katharina; Zupanc, Günther K. H.; Helfrich-Förster, Charlotte (2024). 210(2) 189–201.
Bees are known for their ability to forage with high efficiency. One of their strategies to avoid unproductive foraging is to be at the food source at the right time of the day. Approximately one hundred years ago, researchers discovered that honeybees have a remarkable time memory, which they use for optimizing foraging. Ingeborg Beling was the first to examine this time memory experimentally. In her doctoral thesis, completed under the mentorship of Karl von Frisch in 1929, she systematically examined the capability of honeybees to remember specific times of the day at which they had been trained to appear at a feeding station. Beling was a pioneer in chronobiology, as she described the basic characteristics of the circadian clock on which the honeybee's time memory is based. Unfortunately, after a few years of extremely productive research, she ended her scientific career, probably due to family reasons or political pressure to reduce the number of women in the workforce. Here, we present a biographical sketch of Ingeborg Beling and review her research on the time memory of honeybees. Furthermore, we discuss the significance of her work, considering what is known about time memory today --- nearly 100 years after she conducted her experiments.

Topological Heusler magnets-driven high-performance transverse Nernst thermoelectric generators. Chen, Mengzhao; Wang, Jialu; Liu, Kai; Fan, Wusheng; Sun, Yan; Felser, Claudia; Zhu, Tiejun; Fu, Chenguang (2024). 14(21) 2400411-.
Abstract Topological magnets (TMs) with the coupled topology of electronic band structures and spin configuration have exhibited exotic transport properties that are overwhelmingly appealing for transverse thermoelectric applications. Despite the continuous discovery of TMs in recent years, the development of Nernst generators has much lagged. Here, high-performance Nernst generators are developed utilizing polycrystalline topological Heusler bulk magnets. Benefiting from the robustness of topological effect to grain boundary scattering, polycrystalline Co2MnGa is found to exhibit a large Nernst thermopower of ≈6.5 µV K?1 at 300 K, which is comparable to the previously reported record value in its single crystal. The developed Nernst generators thereby exhibit excellent performance with an output voltage of 5.4 mV and power of 14.3 µW, significantly higher than that of Nernst thermopiles assembled using conventional ferromagnets. These results pave the way to advancing TMs with intrinsically large Berry curvature for transverse thermoelectric applications.
The God-I-Box: Iteratively Provotyping Technology-Mediated Worship Services. Wolf, Sara; Steinmüller, Benedikt; Mörike, Frauke; Luthe, Simon; Hurtienne, Jörn in DIS ’23 (2023). 1710–1723.
The COVID-19 pandemic accelerated the development of alternative formats for religious rituals, such as Protestant online worship services. However, current design approaches focus on problem-solving, and the resulting online solutions merely imitate the offline status quo. To overcome these limitations, we suggest adopting a provotype approach that allows for a more holistic, open-ended dialogue with those affected. We iteratively developed a first provotype in response to tensions found in observation-based field research, aiming to test whether and how it can trigger productive impulses for exploring future technology-mediated worship services based on existing experiences and perspectives. The resulting God-I-Box exaggerates individuality and allows congregants to act almost like liturgists. An analysis of congregants’ and pastors’ (online) first encounters with the God-I-Box revealed three reaction modes: spontaneous emotions, reflective coping, and exploratory imagination. We conclude with reflections and recommendations for provocative research and design in this context and beyond.

In recent years, the trend has increasingly been to store and process data in the cloud. However, this is based on the premise that cloud providers treat the data in a trustworthy manner. One way of using the data in the cloud without the provider having access to it is homomorphic encryption. However, since this encryption has only recently become practicable, analysis of its for practical applications is still in its infancy. Therefore, we investigate the performance of homomorphic encryption using a real-world application, namely linear regression. Our main finding is that although the homomorphic computation of linear regression is in the range of minutes and thus slower than in the non-homomorphic case, linear regression can be computed homomorphic and is therefore suitable for use cases where data security is the top priority.
FUZZY PREPROCESSING OF VIOLA-JONES ALGORITHM FOR FACE RECOGNITION IN THERMAL IMAGES. Martínez, Edwyn E. Martínez (ed.) (2023). (Vol. 13) 1–8.
This paper proposes to improve the Viola-Jones algorithm to identify facial features in thermal images using a fuzzy linguistic modifier. The purpose is to improve the image quality in the infrared plane and to facilitate the recognition stage, feature selection and emotion classification. The results obtained show that adding a preprocessing stage improves the capability of the Viola-Jones algorithm in identifying facial features in thermal images.

Designing Tangible Interactive Artifacts for Religious and Spiritual Purposes. Markum, Robert B.; Wolf, Sara; Hoefer, Michael; Maas, Franzisca in DIS ’23 Companion (2023). 117–120.
From candles to prayer beads to icons and more, tangible artifacts have long played a central role in religious and spiritual life. However, despite growing interest in HCI on design within religious and spiritual contexts, the intentional design of tangible interactive artifacts for religious or spiritual purposes is still relatively uncommon. This workshop aims at advancing our understanding of tangible interactive artifact design in religious and spiritual contexts and how religious and spiritual purposes may offer alternative approaches to design. We invite those interested from all professional and religious/spiritual backgrounds to imagine and design tangible interactive artifacts for religious or spiritual purposes such as beliefs, practices, or rituals. The workshop will include the demonstration of (imagined) artifacts, reflection on designing for religious/spiritual purposes, and hands-on design sessions.
Designing for Uncontrollability: Drawing Inspiration from the Blessing Companion. Wolf, Sara; Luthe, Simon; Baumeister, Lennart; Moerike, Frauke; Janakiraman, Vyjayanthi; Hurtienne, Jörn in CHI ’23 (2023).
This paper presents an inspirational concept for companion technology design, uncontrollability, and a corresponding artefact, the Blessing Companion. Both originated from a research through design project exploring companion technologies for blessing rituals. We established an exchange with Protestant theologians, explored believers’ experiences of blessings, co-speculated on potential technologies, and refined the resulting ideas through ideation, prototyping, and testing. Inspired by believers’ descriptions of blessing experiences as not plannable, predictable, controllable, or enforceable, we adopted the concept of uncontrollability, explored how it might be implemented in companion technologies, and designed the Blessing Companion. The Blessing Companion embodies uncontrollability through its ambiguous appearance and (partly) uncontrollable behaviour. It thus stands in contrast to the prevailing on-demand and user-driven interaction paradigms. We discuss how uncontrollability can be reflected in content, form, and interaction, highlight respective possibilities for companion technologies, and reflect on the Blessing Companion as an example of designing for religious rituals.
Virtual Tourism, Real Experience: A Motive-Oriented Approach to Virtual Tourism. Wolf, Sara; Weber, Michael; Hurtienne, Jörn in CHI EA ’23 (2023).
Virtual tourism products promise to combine the best of two worlds: Staying in the safety of one’s home while having engaging tourism experiences. Previous tourism research has emphasised that tourism experiences involve more than just seeing other places. They address cultural motives such as novelty and education and socio-psychological motives like relaxation, escape from a mundane environment or facilitation of social interaction. We suggest applying the motive-oriented perspective in HCI research on virtual tourism and report on a corresponding analysis of 21 virtual tourism products. Our findings show that current virtual tourism products neglect the breadth of tourist motives. They mainly focus on cultural motives while rarely addressing socio-psychological motives, especially kinship relationships and prestige. Our findings demonstrate the usefulness of the motive-oriented perspective for HCI and inspired conceptual ideas for addressing motives in virtual tourism products that may be useful for future research and design in this area.

Spirituality at the Breakfast Table: Experiences of Christian Online Worship Services. Wolf, Sara; Moerike, Frauke; Luthe, Simon; Nord, Ilona; Hurtienne, Jörn in CHI EA ’22 (2022).
Since the COVID-19 pandemics, we have witnessed an increase in online worship services. Nevertheless, HCI has little insight into how technological mediation influences religious experiences and how technology should be designed for use in religious contexts. Therefore, we see a unique opportunity to understand better real-world experiences of technology use in religious rituals and, more specifically, in online worship services. Inspired by contextual design, We virtually observed and interviewed eight persons during and after participation in online worship services. We identified a field of tension between faith, everyday life, individuality, and community. The data suggests that current online worship service systems do not account for believers’ needs for community, faith, or extraordinariness. We discuss opportunities for future research and design, and aim to contribute to the understanding of online worship service experiences and the design of technology-mediated religious experiences.
Co-Imagining Participatory Design in Religious and Spiritual Contexts. Markum, Robert B.; Wolf, Sara; Luthe, Simon in NordiCHI ’22 Adjunct (2022).
People with religious and/or spiritual interests have long been digitally connected and have engaged in joint prayer, worship, or meditation. However, the COVID pandemic has accelerated this trend as more religious and/or spiritual activities were technologically mediated. Many of these formats had to be implemented quickly, often with little participation from stakeholders. In this workshop, we aim to bring together scholars and practitioners from different backgrounds, such as religious studies, theology, HCI, and participatory design, to start a conversation about what collaborative technological design and research with religious and/or spiritual communities could look like in the future and what needs to be done to get to such futures. The outcomes of this workshop will be the formation of a transdisciplinary research and design community, the establishment of guiding principles and best practices that can inform research and design methodologies, and the dissemination of this knowledge in collaborative post-workshop publications.
UNeedS: Development of Scales to Measure the Satisfaction and Frustration of 13 Fundamental Needs. Wolf, Sara; Maas, Franzisca; Künzl, Pauline; Hohm, Anna; Hurtienne, Jörn in MuC ’22 (2022). 539–544.
Good user experience can be described as the result of satisfying fundamental human needs through interaction with technology. Therefore, HCI researchers and practitioners strive to promote need satisfaction and avoid need frustration through their technology and interaction designs. However, HCI lacks appropriate measurement instruments to examine and evaluate experiences with technology in terms of their satisfaction (or frustration) of needs. Instead, researchers and practitioners frequently use measurement instruments developed in (consumer) psychology that are not tailored to the needs of HCI. Here we report on the development of the User Needs Scales (UNeedS), a set of scales designed to measure the satisfaction and frustration of 13 fundamental needs identified for HCI, and report on our first experiences applying it. Preliminary data indicate good item qualities and internal consistencies, but further research must substantiate these claims. All scales and the full UNeedS are available in the supplemental materials.
‘I Did Digital Tidying up for a More Adult Stage of Life’: Ritualistic Technology Appropriations During Life Transitions. Wolf, Sara; Mörike, Frauke; Löffler, Diana; Hurtienne, Jörn (2022). 34(5) 117–128.
Life transitions, such as the transition from childhood to adulthood, are often accompanied by meaning-making actions such as rituals. Rituals increasingly involve the use of interactive technology. While previous research has focused on specific contexts or technologies, a bird’s eye view of the many appropriation styles during life transitions is missing. To identify the range of technology’s appropriations, we analysed stories from 84 participants and compared these across different life transitions and technologies. We identified three roles interactive technology can play during life transitions: the role of (i) a facilitator easing the accomplishment of tasks within life transitions, (ii) an enabler creating opportunities for new transition rituals and (iii) a social actor that itself is the trigger or the content of transition rituals. We propose the three roles as a classification scheme to structure existing and future research and reflect on the design challenges and evaluation approaches.

[Computers in Statistical Research]: Comment. Utts, Jessica (1986). 1(4) 437–439.
There has been a science fiction novel living in my head for the past 10 years or so... This story occurs 30 to 40 years into the future. There are no more statisticians... The clerk feeds the data into the computer and out pops the appropriate model, estimate, or whatever... No one knows how the computer generates these answers, but everyone knows that if the computer produced them, they must be right... In the current version of the story, something finally goes wrong. I haven't worked out the details, but it is a result which contradicts common sense so much that someone (a fresh young scientist, of course) actually has the audacity to question what is happening in the computer... It seems that when the computer software was being developed, most statisticians didn't pay much attention. The packages which were eventually implemented were written by people who were good at selling, but who didn't really understand the concepts involved.
