    Activity Theory Analysis of Heart Failure Self-Care

    The management of chronic health conditions such as heart failure is a complex process emerging from the activity of a network of individuals and artifacts. This article presents an Activity Theory-based secondary analysis of data from a geriatric heart failure management study. Twenty-one patients' interviews and clinic visit observations were analyzed to uncover eight configurations of roles and activities involving patients, clinicians, and others in the sociotechnical network. For each configuration or activity pattern, we identify points of tension and propose guidelines for developing interventions for future computer-supported healthcare systems

    Pass the Ball: Enforced Turn-Taking in Activity Tracking

    We have developed a mobile application called Pass The Ball that enables users to track, reflect on, and discuss physical activity with others. We followed an iterative design process, trialling a first version of the app with 20 people and a second version with 31. The trials were conducted in the wild, on users' own devices. The second version of the app enforced a turn-taking system that meant only one member of a group of users could track their activity at any one time. This constrained tracking at the individual level, but more successfully led users to communicate and interact with each other. We discuss the second trial with reference to two concepts: social-relatedness and individual-competence. We discuss six key lessons from the trial, and identify two high-level design implications: attend to "practices" of tracking; and look within and beyond "collaboration" and "competition" in the design of activity trackers

    Motivations for OpenLearn: the Open University's Open Content Initiative

    This short paper is a contribution to the Organisation for Economic Co-operation and Development (OECD) expert workshop to help identify "motivations, benefits and barriers for institutions producing open educational resources". The motivations are examined by looking at the reasons behind the launch by the Open University in the UK of a web based collection of open educational resources, OpenLearn. OpenLearn launched on October 25th 2006 and reflects an initiative backed by the William and Flora Hewlett Foundation and the Open University to develop a learning environment (LearningSpace) and an accompanying educator environment (LabSpace) giving free access to material derived from Open University courses. There are of course many reasons for the taking part in open educational resources and so this paper considers motivations in community, organisational, technical and economic terms.The paper was initially prepared for the OECD experts meeting on Open Educational Resources 26-27 October 2006 in Barcelona, Spain

    Data, Data Everywhere, and Still Too Hard to Link: Insights from User Interactions with Diabetes Apps

    Get PDF
    For those with chronic conditions, such as Type 1 diabetes, smartphone apps offer the promise of an affordable, convenient, and personalized disease management tool. How- ever, despite significant academic research and commercial development in this area, diabetes apps still show low adoption rates and underwhelming clinical outcomes. Through user-interaction sessions with 16 people with Type 1 diabetes, we provide evidence that commonly used interfaces for diabetes self-management apps, while providing certain benefits, can fail to explicitly address the cognitive and emotional requirements of users. From analysis of these sessions with eight such user interface designs, we report on user requirements, as well as interface benefits, limitations, and then discuss the implications of these findings. Finally, with the goal of improving these apps, we identify 3 questions for designers, and review for each in turn: current shortcomings, relevant approaches, exposed challenges, and potential solutions

    USING ALGORITHMIC NUDGES TO SAVE ENERGY AND WATER: A PROPOSAL FOR A LONGITUDINAL FIELD EXPERIMENT

    Get PDF
    Energy and water consumption are significant sources of greenhouse gas emissions. While facilitating conservation behaviors in private households can help to mitigate these emissions, the effects of such mitigations are often indirect and delayed. Presenting meaningful feedback about consumption can help to make clear the positive effects of conservation behaviors to those who undertake them. We propose a large-scale field experiment to increase energy and water conservation through algorithmic econudges. We use smart metering data to provide transparency, social references, and information about the environmental effects of conservation behavior. The proposed research is planned in a longitudinal design for 8 weeks in the winter of 2022/23 in Germany. The findings are expected to contribute to scholarly research on nudging and practice as well as to housing providers and policymakers who are interested in green nudging

    The Cognitive Atlas: Employing Interaction Design Processes to Facilitate Collaborative Ontology Creation

    Get PDF
    The Cognitive Atlas is a collaborative knowledge-building project that aims to develop an ontology that characterizes the current conceptual framework among researchers in cognitive science and neuroscience. The project objectives from the beginning focused on usability, simplicity, and utility for end users. Support for Semantic Web technologies was also a priority in order to support interoperability with other neuroscience projects and knowledge bases. Current off-the-shelf semantic web or semantic wiki technologies, however, do not often lend themselves to simple user interaction designs for non-technical researchers and practitioners; the abstract nature and complexity of these systems acts as point of friction for user interaction, inhibiting usability and utility. Instead, we take an alternate interaction design approach driven by user centered design processes rather than a base set of semantic technologies. This paper reviews the initial two rounds of design and development of the Cognitive Atlas system, including interactive design decisions and their implementation as guided by current industry practices for the development of complex interactive systems

    Mobile technology in complex emergencies: A study of digital data collection in the Norwegian relief sector.

    Master's thesis in Societal Safety and Risk ManagementThis thesis presents a study of digital data collection amongst the five largest humanitarian relief organizations in Norway – with data from each actor. More specially, it examines the potentials and challenges in the implementation and diffusion of mobile technologies for the Norwegian NGO relief sector. The term mobile technology is used to describe the various mobile devices used for data collection including mobile phones, tablet computers, laptop computers, and so on. Within the confines of this study, social media was largely excluded. In this thesis, an integrated diffusion/implementation model is presented and applied in the analysis of how mobile technology spread (diffusion) and are applied (implementation). Integrated into this model, are components of sensemaking (ambiguity & uncertainty) and different images of decision making in relief work. The purpose of this model is to explore and highlight the uses and experiences of mobile technology for data collection amongst the different organizations in presenting the matters of diffusion and implementation. The findings suggest that mobile technology is a recognized humanitarian innovation that is diffusing within the Norwegian relief sector. Data collection is becoming faster, cheaper, more efficient, and is providing higher quality data with better oversight. At the same time, with the ease of data collection presents the challenges of data overload, competing solutions, administrative constraints and making sense of the data that is collected. In conjunction with these findings, the thesis concludes that mobile technology is improving the efficiency for collecting information but is not a solution that is effective in all situations and all places
