A plethora of toolkits, checklists, and workshops have been developed to bridge the well-documented gap between AI ethics principles and practice. Yet little is known about effects of such interventions on practitioners. We conducted an ethnographic investigation in a major European city organization that developed and works to integrate an ethics toolkit into city operations. We find that the integration of ethics tools by technical teams destabilises their boundaries, roles, and mandates around responsibilities and decisions. This lead to emotional discomfort and feelings of vulnerability, which neither toolkit designers nor the organization had accounted for. We leverage the concept of moral stress to argue that this affective experience is a core challenge to the successful integration of ethics tools in technical practice. Even in this best case scenario, organisational structures were not able to deal with moral stress that resulted from attempts to implement responsible technology development practices.

ehealth solutions at home are gaining interest and relevance in healthcare; however, they face challenges in sustaining motivation for therapy due to difficulties in creating meaningful connections between technology and people receiving care. in this article, we explore how embodied agents in ehealth interventions could be designed to establish a motivating relationship with people in the context of home-based stroke rehabilitation. We studied this potential by referring to the need for social relatedness in self-Determination-theory (sDt) and how this translates to the design of embodied agents' characters, the collaborations they afford and the partnerships they establish over time. in co-creative ideation sessions with stroke survivors, this potential was explored, resulting in an interactive prototype of 'edo the coach' , i.e. an embodied agent for home-based upper extremity stroke rehabilitation that was evaluated by stroke survivors in their home contexts. Based on the insights gained, we reflect on the potential of using sDt for designing embodied agents that foster motivational relationships between patient and agent as an answer to the growing demand for ehealth-supported self-care within an increasingly digitized healthcare context.

In this paper, we report on methodological insights gained from a workshop in which we collaborated with theater professionals to enact situated encounters between humans and robots on a mixed reality stage combining VR with real-life interaction. We deployed the skills of theater professionals to investigate the behaviors of humans encountering robots to speculate about the kind of interactions that may result from encountering robots in supermarket settings. The mixed reality stage made it possible to adapt the robot’s morphology quickly, as well as its movement and perceptual capacities, to investigate how this together co-determines possibilities for interaction. This setup allowed us to follow the interactions simultaneously from different perspectives, including the robot’s, which provided the basis for a collective phenomenological analysis of the interactions. Our work contributes to approaches to HRI that do not work towards identifying communicative behaviors that can be universally applied but instead work towards insights that can be used to develop HRI that is emergent, and situation- and robot-specific. Furthermore, it supports a more-than-human-design approach that takes the fundamental differences between humans and robots as a starting point for the creative development of new kinds of communication and interaction.

Purpose: eHealth-based exercise therapies were developed to increase stroke patients' adherence to home-based motor rehabilitation. However, these eHealth tools face a rapid decrease in use after a couple of weeks. This study investigates stroke patients' motivation for home-based upper extremity rehabilitation with eHealth tools and their relation with Basic Psychological Needs. Materials and methods: This is a qualitative study using thematic analysis. We conducted semi-structured interviews with stroke patients with upper extremity motor impairments, who were discharged home from a rehabilitation centre, after they interacted with a novel eHealth coach demonstrator in their homes for five consecutive days. Results: We included ten stroke patients. Thematic analysis resulted in eight themes for home-based rehabilitation motivation: Curiosity, Rationale, Choice, Optimal challenge, Reference, Encouragement, Social Support and Trustworthiness. Those themes are embedded into three Basic Psychological Needs: "Autonomy", "Competence", and "Relatedness". Conclusion: Eight motivational themes related to the three Basic Psychological Needs describe stroke patients' motivation for home-based upper extremity rehabilitation. We recommend considering those themes when developing a home-based eHealth intervention for stroke patients to increase the alignment of eHealth tools to the patient's needs and reduce motivational decreases in home-based rehabilitation.

The dramatic acceleration of digital technologies and their integration into physical products is transforming everyday objects. Our domestic appliances, furniture, clothing, are growing in intelligence. Smart objects are increasingly capable of interacting with humans in a purposeful manner with intentionality. This collection of essays, descriptions of empirical work, and design case studies brings together perspectives from interaction design, the humanities, science and technology studies, and engineering, to map, explore and interrogate ways in which our relationships with everyday smart objects might expand and be re-imagined. By offering a critical assessment on the growing place of smart technology in everyday environments, this book outlines a transdisciplinary research agenda for the future of ‘smartness’ to help define, envision, and inspire future collaborative design practices. These essays propose an understanding and design of smart objects that embrace their hybrid nature as shifting and blending tools, agents, machines, or even ‘creatures’. Authors argue that smart objects have the potential to enter into multiple kinds of relationships with humans, and form complex human-nonhuman ecologies that are both meaningful and empowering in the context of everyday life. This book also shines a light on the hidden infrastructures behind the functioning of smart objects with stirring debates tackling questions of technology, human values, and economic and ecological impact. Whether you are a design scholar, design practitioner or design activist this book will inspire through offering theoretical insights, design concepts and practical ways on how to engage in this research agenda for future smartness.
