    Decentralized Business Process Control using Blockchain
    (Enterprise Modelling and Information Systems Architectures (EMISAJ) – International Journal of Conceptual Modeling: Vol. 15, Nr. 15, 2020) Guerreiro, Sérgio Luís; Silva, Diogo; Rosado, Tiago; Vasconcelos, André; Correia, Miguel; Sousa, Pedro
    Many applications supported by blockchain technology are emerging in the industry. Blockchain can be used to enforce the correctness of business process execution and, consequently, increasing the trust among the stakeholders involved in complex business processes. Since few experiences in the area have been reported, more are needed to better understand the benefits and pitfalls of blockchain-based solutions for decentralized business process control. This paper is an experience report of two projects that enforce decentralized business process control using blockchain - a food supply chain and a car registration - using a Design Science Research Methodology approach. Each application follows a different business process design - DEMO and BPMN - leading to different implementations based on Hyperledger Fabric. The major lessons learned are related to the appropriateness of DEMO and BPMN as business process modelling languages in the context of blockchain applications.

    Die Digitalisierung der Wissensarbeit – Handlungsempfehlungen aus der Wirtschaftsinformatik-Forschung
    (HMD Praxis der Wirtschaftsinformatik: Vol. 53, No. 1, 2016) Köffer, Sebastian; Urbach, Nils
    Die Digitalisierung aller Lebensbereiche hat zu steigenden Bedürfnissen und Anforderungen an die technologische Unterstützung am Arbeitsplatz geführt. Die Unternehmen finden sich durch diese Entwicklung in einem Zwiespalt wieder. Einerseits möchten Sie Ihren Beschäftigten vor dem Hintergrund möglicher Effizienzgewinne und Innovationspotenzialen mehr Freiheiten und Autonomie in Bezug auf Auswahl und Einsatz von IT einräumen. Andererseits ist ein Mindestmaß an Kontrolle vor allem aufgrund von Compliance und Steuerbarkeit unerlässlich. Der Beitrag nennt konkrete Handlungsempfehlungen für die Gestaltung des digitalen Arbeitsplatzes, die in der Wirtschaftsinformatik-Forschung abgegeben werden.AbstractThe digitalization of all areas of life has also increased the demand to support digital knowledge work with adequate tools and software. As a result, organizations are caught in a dilemma. On the one hand, they may grant their employees more freedom and autonomy in terms of IT selection to realize innovations and productivity gains. On the other hand, they must monitor their work processes to ensure control and compliance. The article summarizes managerial implications from information systems research about the design of digital knowledge work.

    Exploring Users' Perceived Control over Technology
    (Mensch und Computer 2021 - Tagungsband, 2021) Sieger, Leonie Nora; Detjen, Henrik
    Intelligent systems become more and more a part of our everyday lives and typically act autonomously. Design guidelines and constructs related to the control of traditional systems often do not apply to them. Still, perceived control over these systems is important to users and affect acceptance and intention to use them. This paper presents an explorative online study. Participants named systems over which they sense much or less control and described features and properties that lead to that perception or that affect their desire for control. We found that (1) perceived control is strongly influenced by not directly control-related design features such as effective or efficient use, (2) poor comprehensibility and malfunctioning are highly affecting users control feeling, (3) users value customizability and the possibility for personalization of systems, (4) people are highly aware of privacy control issues of modern online connected technology, and (5) smart systems face the same control-related challenges as non-smart systems, but suffer from still being new to the users. Our findings help to understand the complex phenomena of perceived control over system with different levels of intelligence and autonomy from the users’ perspective and give suggestions for the design of future systems.

    Investigating the Impact of Control in AI-Assisted Decision-Making - An Experimental Study
    (Proceedings of Mensch und Computer 2024, 2024) Meske, Christian; Ünal, Erdi
    We ask whether users should adjust to AI systems or vice versa. Levels of automation (LOAs) are task dependent, may vary within one task, and also may change over time. People’s diverse abilities and preferences make the usage of AI systems possibly personal. Automation design is a complicated task. We investigate varying levels of LOAs in one specific decision-making process. For this, we conduct an experiment, where n=24 volunteers participate in a within-subject face-recognition experiment. Face-recognition is an innate ability mastered by humans. Reason are specialized neurological systems. This also makes it an intuitive task. The results show that of the five tested LOAs, each one leads to personal best and personal worst decisions regarding accuracy and time. Similarly, each LOA is preferred or opposed by participants. This shows, that there is no “one-size-fits-all” LOA, suggesting that careful design is required and multiple LOAs should be offered for a task.

    Personalisierung in der E-Welt Aus dem Blickwinkel der informationellen Selbstbestimmung gesehen
    (Wirtschaftsinformatik: Vol. 49, No. 1, 2007) Roßnagel, Alexander
    Personalisation in the E-World — Seen from the Perspective of Informational Self-Determination. Compared to the material world, data traces will to an increasing degree be used for the purpose of personalisation in the e-world. The article examines both the risks for the self-determination of the data subject and the safeguards of data protection law in this world. It is apparent that the requirements of data protection law are frequently not observed. However, the law is able to form the legal basis of necessary personalisations and to protect the data subject if this process is carried out without his/her consent. It is important to distinguish these single processes from the accumulating effects of ubiquitous electronic personalisation. The latter form fundamental problems for democratic societies, and data protection laws do not have the ability to solve these issues. In contrast, there is a strong need for the separation between personalisation and control on a technical level.

    RFID: Verbraucherängste und verbraucherschutz
    (Wirtschaftsinformatik: Vol. 47, No. 6, 2005) Berthold, Oliver; Günther, Oliver; Spiekermann, Sarah
    RFID introduction is a hotly debated public policy issue. The technology enables physical environments to become more interactive and supportive by tagging each item with a chip that wirelessly communicates with a service-enriched backend infrastructure. Based on a number of user studies at Humboldt-Universität and at the Auto-ID Center, this article presents the major fears associated with RFID introduction. We show to what extent these fears are justified and derive a number of system requirements for giving users more control over an RFID-enabled IT infrastructure. After presenting several recent technical proposals for privacy protection, we focus on the question of controlled access to RFID tags. We conclude with a proposal for an easy-to-use private password model.

    Suggestion Lists vs. Continuous Generation: Interaction Design for Writing with Generative Models on Mobile Devices Affect Text Length, Wording and Perceived Authorship
    (Mensch und Computer 2022 - Tagungsband, 2022) Lehmann, Florian; Markert, Niklas; Dang, Hai; Buschek, Daniel
    Neural language models have the potential to support human writing. However, questions remain on their integration and influence on writing and output. To address this, we designed and compared two user interfaces for writing with AI on mobile devices, which manipulate levels of initiative and control: 1) Writing with continuously generated text, the AI adds text word-by-word and user steers. 2) Writing with suggestions, the AI suggests phrases and user selects from a list. In a supervised online study (N=18), participants used these prototypes and a baseline without AI. We collected touch interactions, ratings on inspiration and authorship, and interview data. With AI suggestions, people wrote less actively, yet felt they were the author. Continuously generated text reduced this perceived authorship, yet increased editing behavior. In both designs, AI increased text length and was perceived to influence wording. Our findings add new empirical evidence on the impact of UI design decisions on user experience and output with co-creative systems.

    Who’s in charge?
    (it - Information Technology: Vol. 63, No. 2, 2021) Novakazi, Fjollë; Johansson, Mikael; Erhardsson, Gustav; Lidander, Linnéa
    Fully automated drive still lies far ahead in the future. Therefore, vehicles with multiple modes of operation will not disappear fully as many road types, traffic and weather conditions will not allow fully automated drive. Instead, fragmented trips with regard to automation will prevail, where drivers will have different levels of automation available at different times. Given this scenario and the complexity of vehicles offering multiple levels of automation with different driving modes depending on prevailing conditions, the need for drivers to understand their responsibility during the different modes becomes critical. The aim of this paper is to contribute to further understanding of how perceived control influences the driver’s mode awareness of and responsibility for the driving task by reporting on an on-road Wizard-of-Oz study under real driving conditions. The results show that when confronted with a vehicle offering both a level 2 and a level 4 driving automation system, drivers have difficulty in determining whether control is allocated to them or to the system. Further results show that perceived control and responsibility for the driving task are closely linked, and that the driver’s perception of the driving system influence how they interact with it. Finally, conclusions are drawn regarding the way perceived control influences mode awareness when interacting with a vehicle that features multiple levels of automation.
