This paper examines the potential of Human-Centered AI (HCAI) solutions to support radiologists in diagnosing prostate cancer. Prostate cancer is one of the most prevalent and increasing cancers among men. The scarcity of radiologists raises concerns about their ability to address the growing demand for prostate cancer diagnosis, leading to a significant surge in the workload of radiologists. Drawing on an HCAI approach, we sought to understand the current practices concerning radiologists’ work on detecting and diagnosing prostate cancer, as well as the challenges they face. The findings from our empirical studies point toward the potential that AI has to expedite informed decision-making and enhance accuracy, efficiency, and consistency. This is particularly beneficial for collaborative prostate cancer diagnosis processes. We discuss these results and introduce design recommendations and HCAI concepts for the domain of prostate cancer diagnosis, with the aim of amplifying the professional capabilities of radiologists.

The coordination of maintenance work in manufacturing poses a crucial productivity factor in small and medium-sized companies (SMEs) but often seems to be rather neglected in practice as well as in much of the literature on maintenance. We shed light upon maintenance coordination work by presenting a design case study conducted in an SME over approximately two years. We took a participatory design-oriented approach, involving all roles on the shopfloor affected by maintenance work. In three major iterations during the pre-study, a release-ready prototype was developed and implemented by the users over the course of one year. The evaluation of the tool showed how a new and mostly unintended practice of information flow, error reporting, and prioritization emerged such that, for instance, foremen becoming a central node of communication, formal prioritization shifting away from higher management, and actual prioritization being done by maintainers. This paper contributes to the body of CSCW work on maintenance practice in SMEs by presenting detailed empirical findings on the coordination work of maintainers, as well as the evaluation of socio-technical interventions into maintenance practices.

Past and current research has shown that Knowledge and Expertise Sharing (KES) is central to the appropriation of enterprise software such as Enterprise Resource Planning (ERP) systems. ERP implementation projects in Small and Medium-sized Enterprises (SMEs) are often driven by research and practice. However, they tend to focus on the 'go live' moment rather than on the subsequent, much longer post-implementation phase. This, we argue, results in decreased utilisation over time and an increased need for workarounds. In this paper, we draw on an empirical study within four organisations which exposes the limitations of KES in ERP implementation projects in SMEs, especially in regard to the preparation of key users. Our findings suggest that, despite key users' essential role in these projects, they are often chosen haphazardly and are ill-prepared. As a result, they cannot fulfil their role of facilitating KES with end users, who end up appropriating ERP systems mostly through 'learning by doing'. This stems directly from complex and largely unrecognised processes involving consultants, hotlines, management, key users and end users. In this paper, we introduce and discuss specific socio-technical, KES-oriented measures which can potentially lead to sustainable KES throughout the ERP life-cycle for longer-term success.

Abstract Within CSCW and HCI, an increasing body of literature has been demonstrating the essential relevance of infrastructures and infrastructuring to the work of people engaging in technologically mediated nomadicity. Tech Nomads – or T-Nomads, as they are sometimes called – not only rely ontechnological, human, andenvironmentalinfrastructural components – such as Wi-Fi, technical support, space, and basic resources such as light and power outlets – but they also have to engage in infrastructuring to mobilise their workplaces and effectively accomplish work in and across different locations. In this article, we bring an infrastructuring perspective to understanding nomadic practices concerning the organisation of complex collaborative events. We introduce findings from a long-term investigation focusing on how infrastructures are re-instantiated with the help of digital technologies, according to emerging demands from T-Nomads. Our findings demonstrate the need for a ‘non-essentialist’ approach to nomadicity, one which recognises the character of nomadic work and its varied aspects in different contexts. We extend the infrastructuring literature by demonstrating how infrastructuring work is done in a complex collaborative initiative, as the organisation of the annual European Social Forum.

In this paper, we introduce an innovative design concept for the curation of data, which we call 'Data Story'. We view this as an additional resource for data curation, aimed specifically at supporting the sharing of qualitative and ethnographic data. The Data Story concept is motivated by three elements: 1. the increased attention of funding agencies and academic institutions on Research Data Management and Open Science; 2. our own work with colleagues applying ethnographic research methods; and 3. existing literature that has identified specific challenges in this context. Ongoing issues entailed in dealing with certain contextual factors that are inherent to qualitative research reveal the extent to which we still lack technical design solutions that can support meaningful curation and sharing. Data Story provides a singular way of addressing these issues by integrating traditional data curation approaches, where research data are treated as 'objects' to be curated and preserved according to specific standards, with a more contextual, culturally-nuanced and collaborative organizing layer that can be thought of as a "Story". The concept draws on existing literature on data curation, digital storytelling and Critical Data Studies (CDS). As a possible design solution for Research Data Management and data curation, Data Story offers: 1) a collaborative workflow for data curation; 2) a story-like format that can serve as an organizing principle; 3) a means of enhancing and naturalizing curation practices through storytelling. Data Story is currently being developed for deployment and evaluation.

Most participation processes in urban planning offer poor incentives, especially for young citizens, hence important citizen's needs are excluded. Our work aims at identifying the degree to which Augmented Reality (AR) might motivate young people. We developed an AR-app with Unity3D to create new interaction concepts for use cases in urban planning. Building projects and environment changes are visualized, so citizens can contribute design ideas to the process. Using a human-centered design approach, we invited different stakeholders to participate. We conducted 40 interviews and a survey, then interaction concepts were evolved by citizens in four participatory design workshops. Our findings show that AR can motivate increased participation in urban planning. We also demonstrate a new approach to engaging low-tech users in designing high-tech solutions such as AR systems by using haptic 3D-tools like Lego or clay. Furthermore, we propose ways in which AR could be used collaboratively and embedded in existing participation processes.

'Infrastructuring' as a concept draws attention to the way in which a designed artefact or system is not the end of the development process. Rather, technology development takes place up to, and including, its successful establishment in an associated body of practices. This places emphasis upon the role of practitioners as designers of their own practice environments. While the activities of professional technology development have been reasonably well discussed and conceptualized, activities that practitioners perform to make things work for them are less acknowledged as a systematic contribution to the successful establishment of the use of IT. This paper considers in particular the so-called 'point of infrastructuring': the moment at which practitioners become aware of opportunities to (re-)design their infrastructures, usually initiated by breakdowns or the recognition of potential innovations and reconsideration of current infrastructural use. From this point onwards, end users themselves may start configuring, tailoring or developing new conventions until a point has been reached in which a new technology usage has been successfully established. However, points of infrastructuring do not only provoke end-user driven in-situ design (or 'infrastructuring') activities. They also evoke so-called 'resonance activities'. These encompass all of the observations and communications that attend upon a point of infrastructure as it becomes visible within a work environment. Examination of resonance activities can be a starting point for a better understanding of the practitioner's activities beyond single infrastructural changes, providing a way of highlighting the relationship between different points of infrastructuring. How to capture and understand resonance activities and how to design technological support for them is still an open question. Based on previous work outlined in the literature and an empirical study that looked at collaborative appropriation activities (the most important aspect of infrastructuring) during 3D printing processes, we outline the concept of sociable technologies as a technological approach for capturing and supporting resonance activities and thus enabling infrastructuring activities more broadly.

3D printers have become continuously more present and are a perspicuous example of how technologies are becoming more complex and ubiquitous. To some extent, the emerging technological infrastructures around them exemplify ways how digitalization will change production machines and lines, in general, in the Internet of Things (IoT). From an End-User Development perspective, the main question is how users can be supported in managing those complex digital production lines. To reach a better understanding, we carefully analyzed 3D printers as an example of highly digitalized production machines with regard to the creative activities of their users that help them to make these machines work for their practices. In our study of appropriation processes, we are concerned with situational and social aspects of the configuration and practice challenges associated with making digitalization work and how IoT technologies can support these collaborative appropriation activities of end users by making these machines more “sociable.” We therefore conceptualize the idea of “Sociable Technologies” and implement a prototype that provides hardware-integrated affordances for communicating and documenting practices of usage. Based on the findings of our evaluation, we derive lessons learnt when aiming at making complex technologies more usable.

Emergencies such as the 2013 Central European flood or the 2013 typhoon Haiyan in Philippines have shown how citizens can organize themselves and coordinate private relief activities. These activities can be found in (physical) groups of affected people, but also within (digital) social media communities. There is an evident need, however, for a clearer picture of what exactly is going on to be available for use by the official emergency services: to enlist them, to keep them safe, to support their efforts and to avoid needless duplications or conflicts. Aligning emergency services and volunteer activities is, then, crucial. In this paper we present a mobile crowd sensing based concept, which was designed as well as implemented as the application CrowdMonitor and facilitates the detection of physical and digital activities and the assignment of specific tasks to citizens. Finally we outline the findings of its evaluation.

Recent disasters have shown an increase in the significance of social media for both affected citizens and volunteers alike in the coordination of information and organization of relief activities, often independently of and in addition to the official emergency response. Existing research mainly focuses on the way in which individual platforms are used by volunteers in response to disasters. This paper examines the use of social media during the European Floods of 2013 and proposes a novel cross-social-media application for volunteers. Besides comprehensive analysis of volunteer communities, interviews were conducted with "digital volunteers" such as Facebook moderators of disaster-related groups. Based on the challenges identified, we designed and implemented the cross-social-media application "XHELP", which allows information to be both, acquired and distributed cross-media and cross-channel. The evaluation with 20 users leads to further design requirements for applications aiming to support volunteer moderators during disasters.

People all over the world are regularly affected by disasters and emergencies. Besides official emergency services, ordinary citizens are getting increasingly involved in crisis response work. They are usually present on-site at the place of incident and use social media to share information about the event. For emergency services, the large amount of citizen-generated content in social media, however, means that finding high-quality information is similar to “finding a needle in a haystack”. This article presents an approach to how a dynamic and subjective quality assessment of citizen-generated content could support the work of emergency services. First, we present results of our empirical study concerning the usage of citizen-generated content by emergency services. Based on our literature review and empirical study, we derive design guidelines and describe a concept for dynamic quality measurement that is implemented as a service-oriented web-application “Social Haystack.” Finally, we outline findings of its evaluation and implications thereof.

Over the last years, digital fabrication technologies such as 3D printers have become more and more common at universities and small businesses as well as in communities of hobbyist makers. The high complexity of such technologies, the rapid technological progress and the close link between hardware and software in this field poses challenges for users and communites learning how to operate these machines, especially in the contexts of existing (and changing) practices. We present an empirical study on the appropriation of 3D printers in two different communities and derive design implications and challenges for building appropriation infrastructures to help users face those challenges and making technologies more sociable.

Emergencies are characterized by high complexity and unpredictability. In order to assess and manage them successfully, improvisation work and informal communication, even beyond local and organizational boundaries, is needed. Such informal practices can facilitate ad hoc participation of units in situation assessment, but this may lack overall situation awareness. This article presents a study on how emergent “collaboration needs” in current work of response teams located on-site and in the control center could be supported by mobile geo-collaboration systems. First, we present the results of an empirical study about informal work and mobile collaboration practices of emergency services. Then we describe the concept of a mobile geo-collaboration system that addresses the aspects detected in the empirical study and that was implemented as an Android application using web sockets, a technology enabling full-duplex ad hoc communication. Finally, we outline the findings of its evaluation in practice and its implications.

Improvisation is necessary when planned decision-making as the main managerial activity does not fit the conditions the practice provides. In these cases, information technology should not just automate planned and structured decisions, but support improvisational practice. In this contribution we present an empirical study about the improvisation work in scenarios of medium to large power outages in Germany. Our focus is on inter-organizational cooperation practices, thus we examined the cooperation of fire departments, police, public administration, electricity infrastructure operators and citizens. Our empirical material allows to describe reasons and conditions for improvisation. Our resulting recommendations address the support of aggregation and visualization of information, a necessary individualization of information compositions, options for collaborative situation assessment, requirements for informal and formal communication, and accessibility of information resources.

Adaptations of business processes are important in work environments, specifically when process-support needs to be tailored according to changing needs. The creation, management, and adaptation of the process models require typically modeling-experts. While these actors are knowledgeable in formalizing and operationalizing processes end-users who do not necessarily possess sophisticated modeling skills know typically local practices and framing conditions best. In this paper, we present an approach to support users in articulating their needs and to involve them into the (re-)design of process specifications. We explore how end-users reflect upon and articulate about business processes. Based on results of a qualitative study, we present a new, paper-based interaction technique, which enables users with little skills to model processes. The resulting process specifications can be transferred either in paper or in digital form into traditional modeling systems for further elaboration.

This video showcase presents our new business process modeling environment, called SiSO, that enables end users to model and adapt business processes. SiSO enhances Service Oriented Architectures through non-technical data, such as usage descriptions of the services and their functions, ratings, and keywords. It uses the box-and-wire UI design principle in a new way to enable end users to collaboratively model business processes in the context of Enterprise Resource Planning systems.

Information and communications technology (ICT) pervades most aspects of our lives and changes everyday's practices in work and leisure time. When designing innovative ICTs, we need to engage with given practices, institutional arrangements, and technological infrastructures. We describe the research framework used at the University of Siegen. It is based on a collection of design case studies in particular fields of practice and identifies cross-cutting issues to compare and aggregate insights between these cases. To illustrate this framework, we describe our research activities and discuss three themes which became important in different design case studies.

In this paper we portray a specific type of knowledge which we term 'nomadic knowledge'. It is required periodically by different actors and travels along foreseeable paths between groups or communities of actors. This type of knowledge lets us question generally held assumptions about the way knowledge is enacted. We illustrate our point with an ethnographical field study analyzing the European Social Forum (ESF), a network of political activist organizations. In this network different actors organize a periodic (biannual) event in which some 13,000 activists participated in 2008. We investigate how knowledge about organizing and managing the ESF is transferred between two events respectively, the actors and communities involved. Our study highlights the specific challenges in sharing nomadic knowledge and the consequences of deficiencies on the organizing process. The paper contributes to a better understanding of knowledge sharing practices and opens new directions for technical support.
