- PublikationSoziale Roboter in organisatorischen Kontexten: Die Rolle von Kultur und zukünftiger Forschungsbedarf(Springer, 2023) Schmiedel, Theresa; Jäger, Janine; Zhong, Jia; Dornberger, Rolf [in: Neue Trends in Wirtschaftsinformatik und eingesetzte Technologien]Die Integration von sozialen Robotern in Unternehmen nimmt stetig zu. Das bedeutet, dass es in Zukunft einen vermehrten Einsatz von physisch verkörperten Robotern geben wird, die mit Menschen sozial interagieren und zusammenarbeiten. In diesem Kapitel skizzieren wir die organisatorischen Kontexte, in denen die aktuelle Forschung soziale Roboter untersucht, und weisen auf kulturelle Herausforderungen hinsichtlich ihrer Implementierung am Arbeitsplatz hin. Wir legen nahe, dass die erfolgreiche Integration von sozialen Robotern in Organisationen eine kulturelle Passung zwischen den in sozialen Robotern eingebetteten Werten und den im organisatorischen Kontext, in dem der Roboter eingesetzt wird, gelebten Werten erfordert. Darüber hinaus schlagen wir eine Agenda für zukünftige Forschung vor, die sich mit den wertebasierten kulturellen Herausforderungen bei der Einführung von sozialen Robotern in organisatorischen Kontexten befasst.04A - Beitrag Sammelband
- PublikationNovel bidirectional multimodal system for affective human-robot engagement(IEEE, 2021) Applewhite, Timothy; Zhong, Jia; Dornberger, Rolf [in: 2021 IEEE Symposium Series on Computational Intelligence (SSCI) Proceedings]Multimodal interaction is an essential prerequisite for affective human-robot engagement. Research on bidirectional, affective multimodal interaction systems investigates systems that recognize a user's affect and generate emotional response based on this user's affect. The presented work investigates a novel bidirectional, affective multimodal interaction system using a social robot and an open-source dialogue system framework, developing a prototype based here on Pepper and Rasa. Compared to special lab robotics systems, the proposed system is more attainable, while incorporating, alongside speech and facial expression, eye gaze as one of the major features to convey emotions as input channels. The system generates and emulates emotional output behaviors based on a user's affect using speech, gestures and emojis. This paper describes the concrete implementation and evaluation of the proposed system. Results of the evaluation show that, although the recognition accuracy of the input channels perform differently well, the system can derive well-defined rule-based emotional output behaviors with a high multimodal accuracy rate in the given test scenarios.04B - Beitrag Konferenzschrift
- PublikationSocial robots in organizational contexts: The role of culture and future research needs(Springer, 2020) Schmiedel, Theresa; Jäger, Janine; Zhong, Jia; Dornberger, Rolf [in: New trends in business information systems and technology. Digital innovation and digital business transformation]The integration of social robots in organizations is on the rise. In the future, an increase in the application of physically embodied robots who socially interact and collaborate with humans is expected. In this chapter, we outline the organizational contexts in which current research examines social robots and point out cultural challenges regarding their implementation in the workplace. We suggest that the successful integration of social robots in organizations requires a cultural fit between values embedded in social robots and values lived in the organizational context in which the robot is deployed. In addition, we propose an agenda for future research that addresses the associated cultural challenges of introducing social robots into organizational contexts.04A - Beitrag Sammelband
- PublikationInvestigating the effects of gaze behavior on the perceived delay of a robot's response(2019) Zhong, Jia; Schmiedel, Theresa; Dornberger, Rolf; Salichs, Miguel A.; Ge, Shuzhi Sam; Ivanova Barakova, Emilia; Cabibihan, John-John; Wagner, Alan R.; Castro-González, Álvaro; He, Hongsheng [in: Social Robotics. 11th International Conference, ICSR 2019, Madrid, Spain, November 26-29, 2019, proceedings]Slow responses of social robots cause user frustration in human robot communication. This paper investigates how far the gaze behavior of a robot, meaning the way the robot looks at its conversation partner, influences the perceived delay of a robot’s response in human-robot conversations. To enhance a natural conversation pattern, a gaze behavior was designed and implemented into a humanoid robot. A within-subject experiment involving 31 test subjects was designed with two conditions (with and without gaze behavior). The results generally show a positive correlation between the gaze behavior that the robot exhibits and the perceived responsiveness of the robot (in the condition with gaze behavior). However, the perceived responsiveness is the same in both conditions. One reason for this finding may be that the response time of the robot might have been generally too short to identify an effect in the experi mental setting. Future research can directly build on our research to assess the relation between gaze behavior and perceived responsiveness in further detail and draw upon the finding that gaze behavior generally plays an important role with regard to the perceived responsiveness of a robot. Robot designers can also build on our research and consider both gaze behavior and additional factors to address a perceived delay in a robot’s response.04B - Beitrag Konferenzschrift
- PublikationComparison of the behavior of swarm robots with their computer simulations applying target-searching algorithms(Engineering and Technology, 2018) Zhong, Jia; Dornberger, Rolf; Hanne, Thomas [in: International Journal of Mechanical Engineering and Robotics Research]This paper investigates the functionality and quality of the implementation of a search and target surrounding swarm robotic algorithm using physical swarm robots named Kilobots. The implementation was developed and tested in the simulator V-REP, then transferred onto the actually running Kilobots: Ten Kilobots were used for the experiment, where one Kilobot acts as the target and nine Kilobots act as the searchers. The algorithm allows the searchers to swarm out to find the target while avoiding collisions with other searchers, to orbit around other searchers, which are closer to the target, and finally to surround the target once it is found. The results of the implementation using the physical Kilobots are compared with the results of two adjusted computer simulations. Differences between the simulations and the real robot implementation are investigated: Discrepancies regarding the locomotion and the communication capabilities are identified and discussed.01A - Beitrag in wissenschaftlicher Zeitschrift

- PublikationComparison of a real kilobot robot implementation with its computer simulation focussing on target-searching algorithms(IEEE, 2018) Zhong, Jia; Umamaheshwarappa, Ramya Ramedeverahalli; Dornberger, Rolf; Hanne, Thomas [in: 2018 International Conference on Intelligent Autonomous Systems (ICoIAS’2018)]This paper presents the functionality and quality of the implementation of a search- and target-surrounding swarm robotic algorithm, which was developed and tested in the simulator V-REP, on actually running Kilobots. Ten Kilobots were used for the experiment where one Kilobot acts as target and nine Kilobots act as searchers. The algorithm allows the searchers to disperse to find the target, to avoid collisions with other searchers, to orbit other searchers, which are closer to the target, and to finally surround the target, once it is found. The results of the implementation using actual, real swarm robots are compared with the results of the computer simulation. Differences between simulation and real robot implementation are discussed. In particular, issues associated with the limitation in the Kilobots’ communication capability and their implications on the algorithm are investigated.04B - Beitrag Konferenzschrift
- PublikationInvestigating the democracy behavior of swarm robots in the case of a best-of-n selection(2018) Pochon, Yann; Dornberger, Rolf; Zhong, Jia; Korkut, Safak; Sundaram, Suresh [in: Proceedings of the 2018 IEEE Symposium Series on Computational Intelligence (SSCI 2018)]In swarm robotics, a challenging task is to let the decentralized acting agents make a joint decision, when the individual robots of the swarm only have partial knowledge of the search space. In this paper, we propose a new nature-inspired method for decision-making in the case of a best-of-n selection, investigating the democracy behavior of honeybees and implementing it in swarm robots. The feasibility of our model is tested using a swarm consisting of real hardware robots, the so-called Kilobots. It is shown that our proposed democratic model proves to be resistant to malicious manipulation in the consensus-finding process. Thus, the democracy behavior of honeybees implemented in swarm robots robustly finds the best-of-n selection.04B - Beitrag Konferenzschrift
