Führung im Zeitalter der künstlichen Intelligenz – Untersuchung der Einflüsse und Auswirkungen in international tätigen Versicherungsunternehmen
(Springer Vieweg, 28.07.2023) Richter, Sarah-Louise; Resch, Dörte; Dornberger, Rolf [in: Neue Trends in Wirtschaftsinformatik und eingesetzte Technologien. Digitale Innovation und digitale Transformation]
Diese Studie untersucht die Auswirkungen von künstlicher Intelligenz (KI) auf die Führung in international tätigen Versicherungsunternehmen. Da das Versicherungswesen ein mustergültiges Beispiel für eine datenintensive Branche ist, setzen Unternehmen bereits KI-gestützte Technologie ein und suchen nach Möglichkeiten für die weitere Nutzung. Jeder wichtige Schritt in der Automatisierung kann jedoch eine Verschiebung im Verständnis von Führung auslösen. Es wurde eine Forschungslücke in Bezug auf Führung in Versicherungsunternehmen festgestellt, die mit dem Einsatz von KI konfrontiert sind. Konkret soll untersucht werden, wie sich Führung durch den Einsatz von KI als Beispiel der Digitalisierung verändern könnte. Für diese Studie wurden im Rahmen eines interpretativen Ansatzes qualitative Daten in 19 semi-strukturierten Interviews erhoben, wobei die Befragten fünf Versicherungsunternehmen mit Hauptsitz in Westeuropa repräsentierten. Die Ergebnisse deuten darauf hin, dass der Einsatz von KI und seine Auswirkungen auf die Führung eng mit den zugrundeliegenden Strukturen der Branche verbunden sind, die überhaupt erst zu dem bestehenden Führungsdiskurs und Selbstverständnis der Organisation geführt haben. Die Auswirkungen von KI hängen wiederum vom Führungsdiskurs und den bestehenden Strukturen ab. Wird KI also nur in Übereinstimmung mit dem aktuellen Diskurs eingesetzt, sind die Auswirkungen auf die Führung minimal. Daraus lässt sich schließen, dass der Einsatz von KI-gestützter Software an sich kaum einen Wandel in der Führung auslösen wird. Dennoch birgt KI ein erhebliches Potenzial für Versicherungsunternehmen. So könnte KI beispielsweise die Kernkompetenzen des Versicherers unterstützen und Unternehmen mit breiteren Ökosystemen und Kundengemeinschaften verbinden.

Determination of weights for multiobjective combinatorial optimization in incident management with an evolutionary algorithm
(IEEE, 2023) Gachnang, Phillip; Ehrenthal, Joachim; Telesko, Rainer; Hanne, Thomas [in: IEEE Access]
Incident management in railway operations includes dealing with complex and multiobjective planning problems with numerous constraints, usually with incomplete information and under time pressure. An incident should be resolved quickly with minor deviations from the original plans and at acceptable costs. The problem formulation usually includes multiple objectives relevant to a railway company and the employees involved in controlling operations. Still, there is little established knowledge and agreement regarding the relative importance of objectives such as expressed by weights. Due to the difficulties in assessing weights in a multiobjective context directly involving decision makers, we elaborate on the autoconfiguration of weighted fitness functions based on nine objectives used in a related Integer Linear Programming (ILP) problem. Our approach proposes an evolutionary algorithm and tests it on real-world railway incident management data. The proposed method outperforms the baseline, where weights are equally distributed. Thus, the algorithm shows the capability to learn weights in future applications based on the priorities of employees solving railway incidents which is not yet possible due to an insufficient availability of real-life data from incident management. https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10339298&tag=1

Measuring the benefits of CI/CD practices for database application development
(2023) Fluri, Jasmin; Fornari, Fabrizio; Pustulka, Elzbieta [in: 2023 IEEE/ACM International Conference on Software and System Processes. ICSSP. Melbourne, Australia, 14-15 May 2023. Proceedings]
Modern software development practices automate software integration and reduce repetitive software engineering work. Automation reduces the time it takes from defining software requirements to deploying the software in production. However, when it comes to database applications, the database integration and deployment are often executed manually, making it costly and error-prone. To mitigate this, we extended current software development methodologies by designing a CI/CD pipeline that takes into consideration the database setting. We report on two industrial case studies in which we implemented a newly designed pipeline and we measure the benefits of integration and deployment automation in database development projects. From a quantitative perspective, we found that introducing CI/CD pipelines reduces failed deployments, improves stability and increases the number of executed deployments. From a qualitative perspective, we interviewed the developers before and after the implementation of the CI/CD pipeline and the results show the CI/CD pipeline brings clear benefits to the development team (i.e., reduced cognitive load). This finding puts current database release practices driven by business expectations such as fixed release windows in question.

Touching space: distributed ledger technology for tracking and tracing certificates
(2023) Moriggl, Pascal; Asprion, Petra; Schneider, Bettina; Scherb, Christopher; Bui, Tung X. [in: Proceedings of the 56th Hawaii International Conference on System Sciences]
Components built into space vehicles and equipment (space products) must meet different regulatory requirements; in detail, each component must be certified and sustainably traceable at all times. Space engineers have expressed the need for an interoperable system to collect, manage and route certifications for components, parts and materials that go into space products. The lack of a unified approach in the European space industry is a challenge for companies involved in product development. This research proposes an open-source, secure, fast and distributed ledger technology (DLT) based solution that fits into any IT environment and is well adapted to the needs of manufacturing companies in the space sector. The results show that a blockchain-based solution based on ‘Hyperledger Fabric’ combined with the InterPlanetary File System is viable. The results can guide other researchers and practitioners to consider DLTs when changing their certification management paradigm with suppliers, customers and auditors.

Peer instruction as teaching method in cybersecurity and data privacy
(International School for Social and Business Studies, 2023) Schneider, Bettina; Asprion, Petra [in: International Journal of Management, Knowledge and Learning]
Cybersecurity and data privacy are important fields today. Basic education in these two interconnected areas should already be offered in schools, as practically everyone today can encounter the dangers and risks of the Internet in terms of data theft, data manipulation or the like. However, the topics of cybersecurity and data privacy are generally abstract, and many people are not interested in such rather technical topics. To arouse interest and provide a certain basic education, we used ‘peer instruction’ combined with storytelling as a promising method. Within the framework of an EU project called GEIGER and with the support of students who have learned data privacy by means of the presented method, the method has been further developed, applied, tested, reflected, and iteratively improved. In summary, the method presented is useful for the topics of cybersecurity and data privacy, but the recommendations compiled must be considered in particular with regard to careful preparation and testing.

The role of gamification in the development of (fake) news literacy in higher education
(IATED, 2023) Jäger, Janine; Eisemann, Christoph; Pimmer, Christoph; Gómez Chova, Luis; González Martínez, Chelo; Lees, Joanna [in: EDULEARN23. Proceedings]
Fake news has become a major societal concern, particularly in the online and social media sphere. Higher education institutions have an important role to play in fostering critical thinking and promoting media and news literacy. Therefore, educators need to explore effective and innovative ways to teach news literacy. Online games have emerged as a potentially promising tool. Against this background, the paper presents a framework that conceptualises competences relevant for news literacy and 'fake' news literacy. It then uses the framework to conduct an evaluation of 17 popular and freely available online games about misinformation and disinformation and their suitability for developing competences relevant to (fake) news literacy in a higher education context. The findings indicate that the games were generally limited in scope and covered only specific news literacy competence areas. The paper discusses the results of the analysis and develops some suggestions for the integration of games in the higher education landscape.

Ein menschlicher Eignungstest für objektorientierte Programmierung im Kontext von KI und maschinellem Lernen
(Springer, 2023) Telesko, Rainer; Jüngling, Stephan; Dornberger, Rolf [in: Neue Trends in Wirtschaftsinformatik und eingesetzte Technologien]
Viele aktuelle IT-Systeme werden auf der Grundlage des objektorientierten (OO) Programmierparadigmas implementiert, das sich in mehr als zwei Jahrzehnten als einer der erfolgreichsten Mechanismen für die Wiederverwendung und Erweiterung von Code erwiesen hat und in vielen Softwarekomponenten und -systemen verwendet wird. In Verbindung mit einem soliden Verständnis von Geschäftsprinzipien und guten Kommunikationsfähigkeiten gilt OO immer noch als eine der Kernkompetenzen bei der Entwicklung von Plattformen und Systemen, die unsere heutige IT-Landschaft bestimmen. Der Selbsteinschätzungstest, den wir als Frühindikator für angehende Studierende der Wirtschaftsinformatik (BIT) entwickelt haben, gibt Aufschluss über das Kompetenzniveau von Studienanfängern und -anfängerinnen und dient als Ausgangspunkt, um über Abstraktionsfähigkeiten im Kontext der aktuellen Digitalisierung und der Zunahme von Komponenten der künstlichen Intelligenz (KI) nachzudenken. Der Artikel erläutert die Relevanz des OO-Denkens auf verschiedenen Abstraktionsebenen im Kontext des Lebenszyklus aktueller Systemarchitekturen und gibt einen Ausblick darauf, wie diese Abstraktionsfähigkeiten beim Wechsel von einem OO-Entwicklungs-paradigma in einen neuen Bereich wiederverwendet werden können, in dem KI und maschinelles Lernen ihren Einfluss auf den Gesamtentwurf von Software-systemen stetig vergrößern werden.

Gesichtserkennung und Wegfindung auf dem humanoiden Roboter Pepper als Ausgangspunkt für soziale Interaktion
(Springer, 2023) Dannecker, Achim; Hertig, Daniel; Dornberger, Rolf [in: Neue Trends in Wirtschaftsinformatik und eingesetzte Technologien. Digitale Innovation und digitale Transformation]
Die Interaktion zwischen humanoiden Robotern und Menschen ist ein komplexer Prozess. Sprache, Gesten und die Erkennung von Kommunikationspartnern sind wichtige Aspekte in einer gut definierten Interaktion. Um natürlicher zu wirken, sollte ein humanoider Roboter nicht stationär sein. Er sollte in der Lage sein, Teil einer Menschenmenge zu sein und sich in einem bestimmten Bereich zu bewegen. Daher ist die Wegfindung wichtig, um einem humanoiden Roboter die Möglichkeit zu geben, mit Menschen an mehr als einem Ort in Kontakt zu treten. Darüber hinaus ist die Erkennung von Kommunikationspartnern das Rückgrat der sozialen Interaktion. In diesem Kapitel wird gezeigt, wie OpenCV, eine bekannte Bildverarbeitungsbibliothek, den Roboter Pepper bei der Erkennung von Kommunikationspartnern und -partnerinnen unterstützt und wie dies der Ausgangspunkt für verschiedene Arten von Smalltalk als Grundlage für einen prototypischen Interaktionsprozess zwischen humanoiden Robotern und Menschen ist. Zusätzlich werden die Navigationsfunktionen diskutiert, die es dem Roboter erlauben, sich autonom zu bewegen und eine bessere Mensch-Roboter-Interaktion zu ermöglichen.

A cyber attack simulation for teaching cybersecurity
(2023) Scherb, Christopher; Heitz, Luc; Grimberg, Frank; Grieder, Hermann; Maurer, Marcel; Gerber, Aurona; Hinkelmann, Knut [in: Proceedings of Society 5.0 Conference 2023]
With the rising number of cyberattacks, such as ransomware attacks and cyber espionage, educating non-cybersecurity professionals to recognize threats has become more important than ever before. However, traditional training methods, such as phishing awareness campaigns, training videos and assessments have proven to be less effective over time. Therefore, it is time to rethink the approach on how to train cyber awareness. In this paper we suggest an alternative approach -- a serious game -- to educate awareness for common cyberattacks. While many serious games for cybersecurity education exist, all follow a very similar approach: showing people the effects of a cyber attack on their own system or company network. For example, one of the main tasks in these games is to sort out phishing mails. We developed and evaluated a new type of cybersecurity game: an attack simulator, which shows the entire setting from a different perspective. Instead of sorting out phishing mails the players should write phishing mails to trick potential victims and use other forms of cyberattacks. Our game explains the intention of each attack and shows the consequences of a successful attack. This way, we hope, players will get a better understanding on how to detect cyberattacks.

Influence of cannabis use on incidence of psychosis in people at clinical high risk
(Wiley, 2023) Chester, Lucy Ann; Valmaggia, Lucia; Kempton, Matthew; Chesney, Edward; Oliver, Dominic; Hedges, Emily; Klatsa, Elise; Stahl, Daniel; van der Gaag, Mark; de Haan, Lieuwe; Nelson, Barnaby; McGorry, Patrick; Amminger, G.

Aims Evidence for case–control studies suggests that cannabis use is a risk factor for the development of psychosis. However, there have been limited prospective studies and the direction of this association remains controversial. The primary aim of the present study was to examine the association between cannabis use and the incidence of psychotic disorders in people at clinical high risk of psychosis. Secondary aims were to assess associations between cannabis use and the persistence of psychotic symptoms, and with functional outcome. Methods Current and previous cannabis use were assessed in individuals at clinical high risk of psychosis (n = 334) and healthy controls (n = 67), using a modified version of the Cannabis Experience Questionnaire. Participants were assessed at baseline and followed up for 2 years. Transition to psychosis and persistence of psychotic symptoms were assessed using the Comprehensive Assessment of At-Risk Mental States criteria. Level of functioning at follow up was assessed using the Global Assessment of Functioning disability scale. Results During follow up, 16.2% of the clinical high-risk sample developed psychosis. Of those who did not become psychotic, 51.4% had persistent symptoms and 48.6% were in remission. There was no significant association between any measure of cannabis use at baseline and either transition to psychosis, the persistence of symptoms, or functional outcome. Conclusions These findings contrast with epidemiological data that suggest that cannabis use increases the risk of psychotic disorder.

Towards a wave approach for value sensitive design in social robotics
(ACM, 2023) Schmiedel, Theresa; Zhong, Jia; Eyssel, Friederike [in: HRI '23 companion. Companion of the ACM/IEEE International Conference on Human-Robot Interaction]
Even though a broad range of social robots are currently available on the market, social robots are not yet an integral part of companies, healthcare providers, or public institutions. This might be due to the fact that the prevalent developer perspective immanently focuses on technological advancements, whereas a human-centered view remains underrepresented. In this paper, we argue that a human-centered perspective which integrates values and beliefs of relevant technology stakeholders needs to complement existing approaches to social robot design. Therefore, we propose to apply value sensitive design (VSD) to improve the process of social robot development and design. Even though VSD has become popular in recent years and it represents an established approach to foster innovative technologies, it has not yet been widely applied in the context of social robotics. Concretely, in this paper we will outline the added value of using VSD for social robots and we will explain how to utilize this methodology to enrich research and practice in social robotics.

A new approach for teaching programming: model-based agile programming (MBAD)
(ACM, 2023) Telesko, Rainer; Spahic, Maja; Hinkelmann, Knut; Pande, Charuta [in: ICIEI 2023. Proceedings of 2023 The 8th International Conference on Information and Education Innovations]
Designing courses for introductory programming courses with a heterogeneous audience (business and IT background as well) is a challenging task. In an internal project of the School of Business at the FHNW University of Applied Sciences and Arts Northwestern Switzerland (FHNW) a group of lecturers developed a concept entitled “Model-based agile development” (MBAD) which supports the learning of elementary programming concepts in an agile environment and builds the basis for advanced courses. MBAD will be used as a basic learning module for various Bachelor programs at the FHNW.

Service Dominant-Logic als Forschungsmethode
(Springer, 2023) Ehrenthal, Joachim; Gruen, Thomas W.; Hofstetter, Joerg S.; Dornberger, Rolf [in: Neue Trends in Wirtschaftsinformatik und eingesetzte Technologien. Digitale Innovation und digitale Transformation]
Im digitalen Zeitalter wetteifern die Unternehmen darum, wie gut ihr Service die Bedürfnisse der Kundschaft erfüllt und Probleme löst. Sie intera- gieren dafür mit immer mehr Akteuren, um ihr Versprechen zu erfüllen. Ein für die Forschung in dieser „neuen“ Welt besonders geeigneter Ansatz ist die Service- Dominant Logic (SDL). Es gibt jedoch keine Leitlinien oder einen allgemein aner- kannten Rahmen für die systematische Durchführung von Forschungsarbeiten zur und mit der SDL. Um diese Lücke zu schließen, wird in diesem Kapitel der Einsatz der SDL in der Forschung untersucht und analysiert. Es gibt Empfehlungen für die Durchführung von SDL in der Forschung und schlägt einen Organisationsrahmen für angewandte Forschungsumgebungen und darüber hinaus vor.

Ontology-driven enhancement of process mining with domain knowledge
(Sun SITE, Informatik V, RWTH Aachen, 2023) Eichele, Simon; Hinkelmann, Knut; Spahic, Maja; Martin, Andreas; Fill, Hans-Georg; Gerber, Aurona; Hinkelmann, Knut; Lenat, Doug; Stolle, Reinhard; Harmelen, Frank van [in: Proceedings of the AAAI 2023 Spring Symposium on Challenges Requiring the Combination of Machine Learning and Knowledge Engineering (AAAI-MAKE 2023)]
Process mining is a technique used to analyze and understand business processes. It uses as input the event log, a type of data used to represent the sequence of activities occurring within a business process. An event log typically contains information such as the case ID, the performed activity’s name, the activity’s timestamp, and other data associated with the activity. By analyzing event logs, organizations can gain a deeper understanding of their business processes, identify areas for improvement, and make data-driven decisions to optimize their operations. However, as the event logs contain data collected from different systems involved in the process, such as ERP, CRM, or WfMS systems, they often lack the necessary context and knowledge to analyze and fully comprehend business processes. By extending the event logs with domain knowledge, organizations can gain a more complete and accurate insight into their business processes and make more informed decisions about optimizing them. This paper presents an approach for enhancing process mining with domain knowledge preserved in domain-specific OWL ontologies. Event logs are typically stored in structured form in relational databases. This approach first converts the process data into an event log which is then mapped with ontology concepts. The ontology contains classes and individuals representing background knowledge of the domain, which supports the understanding of the data. A class for the specific activities forms the link between the event log and the ontology. In this manner, it is possible to map the domain knowledge to a particular case and activity. This allows to determine conditions that must be satisfied for executing tasks and to prune discovered process models if they are too complex. This approach is demonstrated using data from the student admission process at FHNW and has been implemented in Protégé.

Automation of Kahoot! by the humanoid robot Pepper – Comparing results from classes – Robot vs. lecturers
(2023) Dannecker, Achim; Hertig, Daniel; Gómez Chova, Luis; González Martínez, Chelo; Lees, Joanna [in: INTED2023 Proceedings]
Digitization is taking place unchallenged in all areas of life. The accompanying automation is an integral part of this development. This development does not stop in the "classroom" either. Be it that the use of mobile devices is increasingly becoming part of the interaction with students, be it that online offers such as Massive Open Online Course (MOOC) are increasingly used in the context of education or video conferencing systems for teaching such as Adobe Connect. In the future, it would also be conceivable for robots to take over parts of the interaction in the classroom. To check the students' knowledge level or for repetition purposes, there is the possibility to conduct quizzes via Moodle or other platforms. These quizzes are rather traditional and not particularly stimulating, so that there is no great incentive for students to take them unless learning points or similar are awarded. Not everywhere are these types of quizzes used in the classroom. Game-based learning platforms like Kahoot! are finding more and more use in teaching. The quizzes that can be conducted via the Kahoot! web service are more exciting and entertaining for students than those that are possible via Moodle, for example. By conducting quizzes via the web service Kahoot!, they can be made more exciting and entertaining for the students, since, for example, the results after each question are visible to everyone, thus adding a competitive and playful aspect. Nevertheless, if game-based learning platforms such as Kahoot! are used, the quiz progress is generally not commented, but rather "worked through". We have implemented a service that enables the humanoid robot Pepper to do a Kahoot! quiz in class. The service enables Pepper to conduct quizzes independently and with commentary possibilities. Unlike a simple PC, Pepper can use gestures and interactions such as eye contact and changing colors to make the interaction more "human" and emotional. The inclusion of Pepper as the moderator of the quiz might increase its appeal to students and an additional innovative aspect will be added to the quiz. By using the robot, lecturers can be relieved and quizzes that have already been prepared can be conducted without much effort even by people who are not familiar with the subject or inexperienced. The robot is able to keep track of the complete course of the quiz at any time and to comment on it (e.g. now on the first place is…). The execution by "Pepper" would generally have five special aspects: 1. students are given an outlook into the future social interaction of robots and humans. 2. the course of the quiz can be commented by a robot. 3. the quiz can be conducted independently of lecturers. 4. students can experience social interaction with robots themselves and use this experience for the future. We have done several quizzes in different classes with 89 students that experiences Pepper as a moderator and 317 students that experienced lecturers as a moderator. In both settings the students got the same preparation tasks and the same questions within Kahoot! As an outlook it can be seen that the results in both settings a similar in the range of correct answers, time the students need to answer the questions and average of final results.

Students struggle in coming back to face-2-face teaching in evidence based good teaching settings
(IATED, 2023) Dannecker, Achim; Hanke, Ulrike; Gómez Chova, Luis; González Martínez, Chelo; Lees, Joanna [in: INTED2023 Proceedings]
Triggered by the Corona pandemic and the experience gained with online teaching as a result, questions are increasingly being asked today about the extent to which online teaching should continue to play a role in university teaching in the future. This raises the question of what actually characterizes good university teaching and which teaching formats enable good university teaching. Therefore, in this paper we would like to compile the research results from teaching-learning research regarding the quality of university teaching and from this compile overarching criteria of evidence-based good university teaching. Based on this, we would like to take a look at the research on the effectiveness of online teaching. Our thesis is that online teaching per se has no higher or lower effectiveness than face-to-face teaching, but rather that the quality of teaching formats is ensured by the implementation of the criteria of good teaching, which goes in different teaching formats. This leads to the hypothesis that university teaching can be effective and good in any teaching format if these criteria are taken into account. In order to test this hypothesis practically in a study of our own, a face-to-face course designed on the basis of findings about evidence-based good teaching was converted to a purely online format from one day to another. The switch from face-to-face to pure online was made without adapting the course materials or the didactic concept in the core. In this way, the evaluation results of both teaching formats could be directly compared. In addition, the evaluation results of these events were also compared with the evaluation results of all other events at the university in order to determine whether events that take evidence-based criteria of good teaching into account are really evaluated better. Finally, we switched in spring semester 2022 back to face-2-face teaching, again without any changes. What is good teaching anyway? How can we measure what good teaching is? Like many studies, including Ulrich (2020), we would like to define good teaching here: (1) as teaching that is well evaluated by students and (2) as teaching that is conducive to learning. Thus, in the first case, student evaluation results are used to elaborate criteria for good teaching; in the second case, learning success using grades or scores on achievement tests are used as variables for good teaching. To elaborate evidence-based criteria for good teaching, we consulted the syntheses of Schneider and Preckel (2017), of Ulrich (2020), and of Schneider and Mustafic (2015) and use the criteria of good teaching reported there. These have been compiled by the respective authors from meta-analyses. In total the evaluation of four semesters (approx. 800 students) pre COVID19 and three semesters (approx. 600 students) during COVID19 are compared and last post COVID19 the first semester (approx. 200 students). As a first outlook it can be said that the satisfaction during COVID19 remained as good as before, the learning success was slightly lower. Compared to all other courses, the gap became larger in the first semester, but this leveled out somewhat over the three semesters. To an overall higher rating. In the post COVID19 semester this changed. The evaluation became a bit worse as well as the evaluation.

Automatic indexing for MongoDB
(Springer, 2023) Espona, Lucía; Vichalkovski, Anton; Steingartner, William; Pustulka, Elzbieta; Abelló, Alberto; Vassiliadis, Panos; Romero, Oscar; Wrembel, Robert; Bugiotti, Francesca; Gamper, Johann; Vargas Solar, Genoveva; Zumpano, Ester [in: New trends in database and information systems. ADBIS 2023 short Papers, doctoral consortium and workshops: AIDMA, DOING, K-Gals, MADEISD, PeRS, Barcelona, Spain, September 4–7, 2023, roceedings]
We present a new method for automated index suggestion for MongoDB, based solely on the queries (called aggregation pipelines), without requiring data or usage information. The solution handles complex aggregations and is suitable for both cloud and standalone databases. We validated the algorithm on TPC-H and showed that all suggested indexes were used. We report on the performance and provide hints for further development of an automated method of index selection. Our algorithm is, to the best of our knowledge, the first query-based solution for automated indexing in MongoDB.

Increasing well-being through robotic hugs
(2023) Bendel, Oliver; Puljic, Andrea; Heiz, Robin; Tömen, Furkan; De Paola, Ivan; Kido, Takashi; Takadama, Keiki [in: Post-event Proceedings of the AAAI Spring Symposium: Socially Responsible AI for Well-being (AAAI-SRAI 2023)]
This paper addresses the question of how to increase the acceptability of a robot hug and whether such a hug contributes to well-being. It combines the lead author’s own research with pioneering research by Alexis E. Block and Katherine J. Kuchenbecker. First, the basics of this area are laid out with particular attention to the work of the two scientists. The authors then present HUGGIE Project I, which largely consisted of an online survey with nearly 300 participants, followed by HUGGIE Project II, which involved building a hugging robot and testing it on 136 people. At the end, the results are linked to current research by Block and Kuchenbecker, who have equipped their hugging robot with artificial intelligence to better respond to the needs of subjects.

A system of customer co-creation for new product development of digital products with a pilot study of the Swiss media industry
(2023) Le Cunff, Eric; Schlick, Sandra; Gerber, Aurona; Hinkelmann, Knut [in: Proceedings of Society 5.0 Conference 2023]
In the age of digitisation, the media industry is faced with declining advertising revenues. Therefore, the focus on the development of new digital products is a key element to survive in such a fast-changing market and to increase the innovation performance. One of the most important elements thereby is the involvement of customers as co-creators in the new product development (NPD) process, so that new digital products are developed that are in demand on the market. However, the process of how companies turn external knowledge from customers into knowledge creation for generating new ideas and the development of innovative products has not been analysed. This pilot study, which presents an initial system of customer co-creation for NPD of digital products from the literature and searches for similarities and dissimilarities through an abductive qualitative data analysis from interviews with three managers in three different Swiss media companies, explores this unresolved research gap. The system of this study is based on an overarching phase model, which is derived from Application Lifecycle Management (ALM). The process anchored in it, which focuses on the customer co-creation of digital products, integrates process elements from the two user-centered approaches, namely User Centered Design (UCD) and Design Thinking (DT). The results from the interviews show that the system is largely in line with the NPD process procedures in the three media companies. It was found that customers can be involved everywhere in the NPD process, but that this is not yet implemented in practice. However, as the future ambition in media companies is to become even more customer- centric, the proposed system in this study is very promising.
