The aim of this work was to develop a valid and reliable scale to measure Basic Psychological Need Satisfaction for technology use (BPN-TU). According to the Self-Determination Theory, satisfaction of the Basic Psychological Needs (BPNs) for Autonomy, Competence, and Relatedness is crucial to well-being and autonomous motivation. Research into the...

Trust calibration is essential in AI-assisted decision-making tasks. If human users understand the reasons for a prediction of an AI model, they can assess whether or not the prediction is reasonable. Especially for high-risk tasks like mushroom hunting (where a wrong decision may be fatal), it is important that users trust or overrule the AI in th...

Understanding the recommendations of an artificial intelligence (AI) based assistant for decision-making is especially important in high-risk tasks, such as deciding whether a mushroom is edible or poisonous. To foster user understanding and appropriate trust in such systems, we assessed the effects of explainable artificial intelligence (XAI) meth...

Explainable Artificial Intelligence (XAI) enables an Artificial Intelligence (AI) to explain its decisions. This holds the promise of making AI more understandable to users, improving interaction, and establishing an adequate level of trust. We tested this assertion in the high-risk task of mushroom hunting, where users have to decide whether a mus...

A recent literature review on personal space in human-robot interaction identified a research gap for the influence of contextual factors. At the same time, psychological research on interpersonal distancing as well as theoretical considerations based on compensatory control models suggest the importance to consider these factors in robot path plan...

There is a confidence crisis in many scientific disciplines, in particular disciplines researching human behavior, as many effects of original experiments have not been replicated successfully in large-scale replication studies. While human-robot interaction (HRI) is an interdisciplinary research field, the study of human behavior, cognition and em...

Egal in welchem Anwendungsbereich soziale Roboter zum Einsatz kommen, sie sind in jedem Fall dafür gemacht, mit Menschen zu interagieren. Die Psychologie als Wissenschaft menschlichen Denkens, Fühlens und Verhaltens kann im Austausch mit anderen Disziplinen daher wertvolle Beiträge zur Erforschung sozialer Roboter und zum Gelingen von Mensch-Robote...

The “Computers are social actors” (CASA) assumption (Nass and Moon in J Soc Issues 56:81–103, 2000. https://doi.org/10.1111/0022-4537.00153) states that humans apply social norms and expectations to technical devices. One such norm is to distort one’s own response in a socially desirable direction during interviews. However, findings for such an ef...

Eine zunehmende Variantenvielfalt durch kundenindividuelle Produkte führt zu besonderen Anforderungen an die Logistik und die Montage in Produktionsumgebungen. Komponenten und Werkzeuge müssen flexibel und auftragsspezifisch an der entsprechenden Station bereitgestellt und genutzt werden. Diesem Sachverhalt stehen hohe und weiter steigende Löhne in...

Technological innovations are oftentimes accompanied by organizational change processes. A new context-specific questionnaire was developed as a diagnostic tool to measure workers’ attitudes toward mobile manufacturing robots to provide a basis for managerial decisions and interventions – the “Attitudes toward Cooperative Industrial Robots Question...

Im Rahmen des Projekts „FORobotics“ wurden mobile Robotersysteme in industriellen Unternehmen eingesetzt. Um den Einsatz strukturiert zu evaluieren, wurde eine Methode zur Evaluation entwickelt. Der Beitrag beschreibt den Einsatz des mobilen Roboters bei der Mey Maschinenbau Prien GmbH & Co. KG und die Evaluation des Einsatzes mithilfe der entwicke...

With the development of mobile robots, research on interpersonal distances grew by a new body of research introducing new opportunities to environmental psychology. In this review, an overview of the literature on interpersonal distances focusing on human-robot interaction is given. Findings on the most prominent factors are summarized and discusse...

User-friendly Companion Systems require Artificial Intelligence planning to take into account human planning behavior. We conducted a qualitative exploratory study of human planning in a knowledge rich, real-world scenario. Participants were tasked with setting up a home theater. The effect of strategy knowledge on problem solving was investigated...

One of the main goals of the collaborative research project FORobotics is to gain new insights into human-related aspects and pro-cesses that might be essential to the development and effective implementation of cooperative mobile robots. In order to achieve this goal, a qualitative, task-related work system analysis was conducted as a first step....

A promising field of application for cognitive technical systems is individualised user assistance for complex tasks. Here, a companion system usually uses an AI planner to solve the underlying combinatorial problem. Often, the use of a bare black-box planning system is not sufficient to provide individualised assistance, but instead the user has t...

In this paper, a new approach to display Braille is presented. Braille dots are mapped to six tactors of a vibrotactile wristband. The dot patterns of characters are displayed with adequate vibrotactile stimuli generated by the tactors. Compared to the conventional way of reading Braille, the advantage of the proposed approach is that there is no n...

The ability to comprehend new information is closely related to the successful acquisition of new knowledge. With the ubiquitous availability of the Internet, the procurement of infor-mation online constitutes a key aspect in education, work, and our leisure time. In order to investigate individual differences in digital literacy, testtakers were p...
