Open Access Series in Informatics (OASIcs) N2 - Mixed Reality (MR) is a technology with strong potential for advancing research in Human-Robot Interaction (HRI) for space exploration. Apart from the efficiency and high flexibility MR can offer, we argue that its benefits for HRI research in space contexts lies particularly in its ability to aid human-in-the-loop development, offer realistic hybrid simulations, and foster broader participation in HRI research in the space exploration context. However, we believe that this is only plausible if MR-based simulations can yield comparable results to fully physical approaches in human-centred studies. In this position paper, we highlight several arguments in favour of MR as a tool for space HRI research, while emphasising the importance of the open question regarding its scientific validity. We believe MR could become a central tool for preparing for future human-robotic space exploration missions and significantly diversify research in this domain.

How women and men perceive autonomous social robots that have a gender bias T2 - MuC '24: Proceedings of Mensch und Computer 2024, Karlsruhe Germany September 1-4, 2024 N2 - Abstract Future social robots will act autonomously in the world. Autonomous behavior is usually realized by using AI models built with real-world data, which often reflect existing inequalities and prejudices in society. Even if designers do not intend it, there are risks that robots will be developed that discriminate against certain users, e. g. based on gender. In this work, we investigate the implications of a gender-biased robot that disadvantages women, which unfortunately is a bias in AI that is often reported. Our experiment shows that both men and women perceive the gender-biased robot to be unfair. However, our work indicates that women are more aware that a gender bias causes this unfairness. We also show that gender bias results in the robot being perceived differently. While the gender bias resulted in lower likability and intelligence ratings by women, men seem to lose trust in the robot if it behaves unfairly.

In hybrid teams of humans and robots, trust enables smooth collaboration and reduces risks. Just as collaboration between humans and robots differs from interpersonal collaboration, so does the nature of trust in human-robot interaction (HRI). Therefore, further investigations on trust formation and dissolution in HRI, factors affecting it, and means for keeping trust on an appropriate level are needed. However, our knowledge of interpersonal trust and trust in autonomous agents cannot be transferred directly to HRI. In this paper, we present a study with 32 participants on trust formation and dissolution as well as forecasting to influence trust in an industry robot. Results show differences in dynamics and factors of trust formation and dissolution. Additionally, we find that the effect of forecasting on trust depends on task success. These findings support the design of trustful human-robot interaction and corresponding robotic team members.

Supporting people for whom this freedom is limited due to physical impairments is the fundamental goal of this thesis. Especially for people who are paralyzed, even working at a desk job is often not feasible. Therefore, in this thesis a prototype of a robot assembly workstation was constructed that utilizes a modern Augmented Reality (AR)-Head-Mounted Display (HMD) to control a robotic arm. Through the use of object pose recognition, the objects in the working environment are detected and this information is used to display different visual cues at the robotic arm or in its vicinity. Providing the users with additional depth information and helping them determine object relations, which are often not easily discernible from a fixed perspective. To achieve this a hands-free AR-based robot-control scheme was developed, which uses speech and head-movement for interaction. Additionally, multiple advanced visual cues were designed that utilize object pose detection for spatial-visual support. The pose recognition system is adapted from state-of-the-art research in computer vision to allow the detection of arbitrary objects with no regard for texture or shape. Two evaluations were performed, a small user study that excluded the object recognition, which confirms the general usability of the system and gives an impression on its performance. The participants were able to perform difficult pick and place tasks with a high success rate. Secondly, a technical evaluation of the object recognition system was conducted, which revealed an adequate prediction precision, but is too unreliable for real-world scenarios as the prediction quality is highly variable and depends on object orientations and occlusion.

Daher ist für Menschen, die beispielsweise vom Hals abwärts gelähmt sind, sogenannten Tetraplegikern, jede Zurückgewinnung von Autonomie eine Steigerung der Lebensqualität. In dieser Masterarbeit wird ein Augmented Reality Prototyp entwickelt, der es Tetraplegikern oder Menschen mit einer ähnlichen körperlichen Einschränkung erlaubt, an einem Mensch-Roboter Arbeitsplatz Montageaufgaben durchzuführen und ihnen somit eine Integration ins Arbeitsleben ermöglichen kann. Der Prototyp erlaubt es den Benutzer ohne die Nutzung der Hände, einen Kuka iiwa Roboterarm mit der Microsoft HoloLens zu steuern. Dabei wird ein Fokus darauf gelegt, das Blickfeld des Benutzers mit speziellen virtuellen Visualisierungen, sogenannten visuellen Helfern, anzureichern, um die Nachteile, die durch die Bewegungseinschränkungen der Zielgruppe ausgelöst werden, auszugleichen. Diese visuellen Helfer sollen bei der Steuerung des Roboterarms unterstützen und die Bedienung des Prototyps verbessern. Eine Evaluation des Prototyps zeigte Tendenzen, dass das Konzept der visuellen Helfer den Benutzer den Roboterarm präziser steuern lässt und seine Bedienung unterstützt.

März 2018 in Chicago (USA) The 1st International Workshop on Virtual, Augmented, and Mixed Reality for Human-Robot Interactions (VAM-HRI), held in conjunction with ACM/IEEE Human-Robot Interaction N2 - This paper presents an approach to enhance robot control using Mixed-Reality. It highlights the opportunities and challenges in the interaction design to achieve a Human-Robot Collaborative environment. In fact, Human-Robot Collaboration is the perfect space for social inclusion. It enables people, who suffer severe physical impairments, to interact with the environment by providing them movement control of an external robotic arm. Now, when discussing about robot control it is important to reduce the visual-split that different input and output modalities carry. Therefore, Mixed-Reality is of particular interest when trying to ease communication between humans and robotic systems.

Oktober 2018 in Karlsruhe N2 - Selbstständig und selbstbestimmt essen und trinken zu können gehört zu den Grundbedürfnissen des Menschen und wird den Aktivitäten des täglichen Lebens (ATLs) zugeordnet. Körperliche Beeinträchtigungen, die mit Funktionsverlusten in Armen, Händen und ggf. der Beweglichkeit des Oberkörpers einhergehen, schränken die selbstständige Nahrungszufuhr erheblich ein. Die Betroffenen sind darauf angewiesen, dass ihnen Getränke und Mahlzeiten zubereitet, bereitgestellt und angereicht werden. Zu dieser Personengruppe gehören Menschen mit querschnittbedingter Tetraplegie, Multiple Sklerose, Muskeldystrophie und Erkrankungen mit ähnlichen Auswirkungen. Derzeit gibt es verschiedene assistive Technologien, die das selbstständige Essen und Trinken wieder ermöglichen sollen.Wie aber muss ein Interaktionsdesign für einen Roboterarm gestaltet sein, damit er von den Betroffenen zur Nahrungsaufnahme genutzt werden kann? Welche Anforderungen gibt es und welche Aspekte sind in Bezug auf die Akzeptanz eines Roboterarms zu berücksichtigen?
