    Intuitive hand gestures for the interaction with information visualizations in virtual reality
    (Springer, 2019) Frey, Gabriel; Jurkschat, Arno; Korkut, Safak; Lutz, Jonas; Dornberger, Rolf; Jung, Timothy; tom Dieck, M. Claudia [in: Augmented reality and virtual reality. The power of AR and VR for business]
    The development of virtual reality provides opportunities for immersive information visualizations and therefore it is expected to facilitate the exploration and understanding of data. Hand gesture control enables intuitive interaction and thus it is suggested to amplify the level of immersion further. This paper conducts and experiment to identify a set of intuitive gestures when interacting with an information visualization. Participants are asked to provide hand gestures to given information seeking tasks in an interactive data visualization application in virtual reality that they did not know in advance. The results are analysed and findings with intuitive gestures are communicated and discussed.

    A case study: assessing effectiveness of the augmented reality application in Augusta Raurica
    (Springer, 2019) Armingeon, Moritz; Komani, Pleurat; Zanwar, Trupti; Korkut, Safak; Dornberger, Rolf; tom Dieck, M. Claudia; Jung, Timothy [in: Augmented reality and virtual reality. The power of AR and VR for business]
    This paper aims to study and compare the augmented reality experience of two user groups at Augusta Raurica, a Roman archaeological site and an open-air museum in Switzerland. The user groups differentiated within the scope of this study digital natives and digital immigrants. The paper applies the experience economy framework for assessing the differences between the user groups. The data gathered from the surveys and analysis of selected interviews reveal that digital immigrants have better engagement with the augmented reality application of Augusta Raurica than digital natives do. The findings are supporting the debate on assisting tourism destinations to develop more engaging augmented reality content targeting both user groups.

    Optimization of multi-robot sumo fight simulation by a genetic algorithm to identify dominant robot capabilities
    (2019) Lehner, Joël Enrico; Dornberger, Rolf; Simic, Radovan; Hanne, Thomas [in: 2019 IEEE Congress on Evolutionary Computation (CEC 2019). Proceedings]
    This paper analyzes the multirobot sumo fight simulation. This simulation is based on a computational model of several sumo fighters, which physically interact while trying to move the opponent out of the arena (lost fight). The problem is optimized using a genetic algorithm (GA), where the capabilities of not only one particular robot but of all robots simultaneously are improved. In this particular problem setup, the problem definition changes depending on the optimization path, because all robots also get better, competing against each other. The influence of different operators of the GA is investigated and compared. This paper raises the questions, which genetically controlled capabilities (e.g. size, speed) are dominant over time and how they can be identified by a sensitivity analysis using a GA. The results shed light on which parameters are dominant. This experiment typically opens up interesting fields of further research, especially about how to address optimization problems, where the optimization process influences the search space and how to eliminate the factor of randomness.

    Recommendations for conducting service-dominant logic based research
    (Springer, 2019) Ehrenthal, Joachim; Gruen, Thomas W.; Hofstetter, Joerg S.; Dornberger, Rolf [in: New trends in business information systems and technology. Digital innovation and digital business transformation]
    While Service-Dominant logic (SDL) has been the basis for research publications in many journals, anecdotal evidence suggests that there is growing resistance to using SDL because some reviewers consider it to be unviable for rigorous research. As a remedy, researchers, editors, and reviewers are in need for clear criteria on what makes good quality SDL research. Our study aims to address this problem, and it examines how SDL has been successfully and unsuccessfully used in research—including methods, processes, and approaches to apply & integrate SDL in research studies—in order to determine a set of quality criteria for researchers and practitioners to better use and benefit from SDL.

    Investigating 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.

    Comparison 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.

    Digital transformation management and digital business development
    (Springer, 2018) Schwaferts, Dino; Baldi, Shama; Dornberger, Rolf [in: Business information systems and technology 4.0. New trends in the age of digital change]
    In a study on the subject of digital transformation carried out by the University of Applied Sciences and Arts Northwestern Switzerland from April to May 2017, 82% of the companies stated that their driver for digital transformation was their wish to support their business processes. However, the majority of companies also stated that, in addition to the desired process support, they observed a greater impact on individual elements of the business model. The aim of this chapter is to explain these observations and their correlations, as well as to provide an approach regarding how digital transformation could be managed systematically against the background of its impact on the business model. Thereby, the terms “Digital Business Development” and “Business Stream Matrix” are used. Building on this approach of digital transformation management, the question is raised as to whether classical management concepts are still adequate to guide companies during and after digital transformation. Where there are management gaps, this chapter substantiates approaches to close these gaps. The term “digital leadership” is used. This chapter concludes with an approach to the “sociotechnical framework”, outlining and substantiating a possible form of organization to which digital transformation tends.

    How to teach blockchain in a business school
    (Springer, 2018) Dettling, Walter; Dornberger, Rolf [in: Business information systems and technology 4.0. New trends in the age of digital change]
    There are different approaches to developing a syllabus for a “blockchain curriculum” in a business school. The following chapter identifies many questions which can guide lecturers through their own process of creating a blockchain syllabus. The list of topics and figures presented indicate how much time could be spent on these topics. This list does not present a definite syllabus, because the essence of blockchain is that it is a holistic approach which goes beyond naming topics. It raises certain questions and is intended to start a broader discussion which will eventually lead to a systematic approach to this multidimensional challenge. Structuring this journey leads to the following four main questions, which are considered relevant in this discussion: What are the key research topics in blockchain? What is the impact of blockchain and by what criteria do we define impact? Which building blocks of blockchain are relevant to understanding the blockchain mechanism? Which applications (beside Bitcoin) should be discussed and are expected to become important in the near and distant future? This journey closes with some methodological remarks based on my experience of teaching blockchain classes. Finally, it is obvious that any curriculum will be condemned to continuous adaption because blockchain technology is changing in an ongoing way.

    ERP systems towards digital transformation
    (Springer, 2018) Asprion, Peter; Schneider, Bettina; Grimberg, Frank; Dornberger, Rolf [in: Business information systems and technology 4.0. New trends in the age of digital change]
    Enterprise Resource Planning (ERP) systems employ highly integrated business software solutions that have existed for many years. Being the base of the IT application landscape of most enterprises, ERP systems remain fairly commoditized and scarcely leave room for differentiation. In view of the major digital transformations currently taking place, the role of ERP systems needs to be reconsidered. Geoffrey Moore’s concept of “Systems of Engagement” stresses the need for enterprise applications to become more user-oriented in order to support collaboration and to empower employees. Based on this understanding, we developed a model that classifies how ERP systems can evolve depending on its people-centricity focus and its level of integration.

    Prototype-based research on immersive virtual reality and on self-replicating robots
    (Springer, 2018) Dornberger, Rolf; Korkut, Safak; Lutz, Jonas; Berga, Janina; Jäger, Janine; Dornberger, Rolf [in: Business information systems and technology 4.0. New trends in the age of digital change]
    This chapter presents our recent research in the field of virtual reality (VR) and self-replicating robots. The unifying approach lies in the research philosophy of using consumer market gadgets, mostly developed for the gaming and entertainment business, in order to design and implement research prototypes. With the prototypes, our research aims to better understand real-world problems and derive practice-oriented solutions for them. In the field of VR, these prototypes are dedicated to identifying new business-relevant use cases in order to provide an additional benefit for business and society. A wide range of examples, such as claustrophobia treatment, financial data analysis, gesture control and voice navigation are discussed. In the field of robotics, the idea of self-replicating robots governs particular research questions. Here, the focus is on using model prototypes enriched with artificial intelligence for indoor navigation, computer vision and machine learning. Finally, the prototype-based research approach using gadgets to produce results is discussed.
