Balancing automation and control: User perceptions of tool invocations in conversational agents
Advances in large language models (LLMs) have enabled conversational agents (CAs) to invoke external functions dynamically, yet little is known about how different tool-calling (TC) strategies affect user experience. This study compares two approaches – automatic execution based on conversational context versus user-confirmed execution – using a German-language CA in a business-travel scenario. In a between-subjects experiment, 451 employed adult…
Bridging Work of Intermediaries: A Qualitative Study on how Five Intermediary Firms Implement Interoperability in Cross-Boundary Infrastructures of Consumer Markets
Managing private life and household affairs requires considerable work for consumer households, sometimes in cooperation with private companies or public administrations. In their role as consumers/citizens, people must perform work such as monitoring and managing supplies and contracts, comparing and purchasing offers, submitting insurance claims, or renewing passports. While some CSCW studies have examined intra-household coordination work, thi…
The Burden of Administrative Household Labor—Measuring Temporal Workload, Mental Workload, and Satisfaction
This research paper investigates the temporal and mental workload as well as work satisfaction regarding bureaucratic, administrative household labor, with a focus on socio-demographic differences. The study utilizes a paid online survey with 617 socio-demographically distributed participants. The results show significant differences in the temporal workload of different chore categories and in the quality of work, whereby satisfaction and mental…
Finding, getting and understanding: The user journey for the GDPR’S right to access
In both data protection law and research of usable privacy, awareness and control over the collection and use of personal data are understood to be cornerstones of digital sovereignty. For example, the European General Data Protection Regulation (GDPR) provides data subjects with the right to access data collected by organisations but remains unclear on the concrete process design. However, the design of data subject rights is crucial when it com…

The Automation of the Taxi Industry – Taxi Drivers’ Expectations and Attitudes Towards the Future of their Work
Advoc ates of autonomous driving predict that the occupation of taxi driver could be made obsolete by shared autonomous vehicles (SAV) in the long term. Conducting interviews with German taxi drivers, we investigate how they perceive the changes caused by advancing automation for the future of their business. Our study contributes insights into how the work of taxi drivers could change given the advent of autonomous driving: While the task of dri…
Research into Design-Research Practices
The aim of this chapter is to outline a research agenda. Here, this agenda has been termed “meta-research into practice-based computing”; the chapter uses the authors’ own work to exemplify elements of it. Such an agenda requires coherent framing and needs to be conducted in sufficient breadth and depth and so is still evolving. The chapter first presents some of the driving forces behind “post-normal” interdisciplinary science carried out in res…
Socio-Informatics: A Practice-Based Perspective on the Design and Use of IT Artifacts
The book is an exploration of the theoretical, conceptual and methodological foundations of human-centred design. Specifically, it critically examines the notion of 'practice' and argues for an understanding of the concept which emanates from engagement with design problems rather than simply from social scientific theory. The contributors to the book in their various ways all subscribe to a systematic account of how practice- oriented studies ca…
Grounded Design
This chapter presents grounded design as a suggestion for a praxeological turn in the field of computing. It argues that, given the high societal relevance of computing to all aspects of life, the academic field of (applied) computer science needs to develop its epistemological paradigm and research methods accordingly. Computer science arguably needs to define itself as a sociotechnical discipline that contributes to the solution of social probl…
Dealing with Personal Data in the Age of Big Data Economies
The technological development of the digital computer and new options to collect, store and transfer mass data have changed the world in the last 40 years. Moreover, due to the ongoing progress of computer power, the establishment of the Internet as critical infrastructure and the options of ubiquitous sensor systems will have a dramatic impact on economies and societies in the future. We give a brief overview about the technological basics espec…

Come_IN: Using Computers to Foster the Integration of Migrant Communities
Modern western societies are facing the challenges of immigration and integration. The main criterion for social participation and democratic collaboration is the successful integration of immigrants. A lack of social as well as cultural integration, especially among young immigrants, seems to be the consequence of a low level of education and unequal opportunities. Immigrant children who are enrolled at primary schools, for instance, show signif…
