    Brinkel J. A user-centred evaluation of a mobile phone-based interactive voice response system to support infectious disease surveillance and access to healthcare for sick children in Ghana: users’ experiences, challenges and opportunities for large-scale application. Part of a concept and pilot study for mobile phone-based Electronic Health Information and Surveillance System (eHISS) for Africa. Bielefeld: Universität Bielefeld; 2020.Digital Health offers tremendous potential to change the face of health systems in all countries. Although the application of digital technologies in the health sector has become central to global health thinking, various implementation barriers still exist. One of the most significant is the process of user acceptance and adoption of new interventions, which still remains a neglected research area in sub-Saharan Africa. The synopsis is a synthesis of the findings of a three-year research study embedded within a larger research consortium that developed and piloted a mobile phone-based Electronic Health Information and Surveillance System for sub-Saharan Africa (eHISS) in Ghana. The system aimed to support sick children to assess the disease severity, to advice appropriate treatment and to collect data on the occurrence of symptom clusters. The thesis evaluated the usability and acceptance among users of the mobile health (mHealth) system (caregivers of children) by soliciting their views on their experiences while using the system. The doctoral thesis followed a human-centred design (HCD) circle and consisted of the following research activities; (i) the assessment of the state of research, (ii) the innovative field test of a prototype of the eHISS system and an assessment of users’ needs to drive the design, (iii) the evaluation of the clinical decision algorithm as backbone of the electronic system and (iv) the evaluation of experiences with the system after a six-month pilot phase of the system. A manuscript was developed from each research activity for publication, thus making a total of four papers that form the empirical basis of this thesis. Results showed that users are generally open to mHealth and interested in new technologies, and comprehensive knowledge on critical factors favouring and disfavouring the integration of the system in the daily life of participants, and suggestions on how the system could be improved has been gained. The thesis thus confirmed and highlighted the key role of user experiences in the design process of new mHealth approaches, and provided insights on how to develop and evaluate mobile health approaches from the user perspective. Based on the results of the user evaluation, two possible directions for the future of eHISS have been developed. We further conclude that programs and initiatives must be guided by robust strategies to overcome existing barriers for implementation. Like all digital health interventions, the presented eHISS system is not a silver bullet and has significant limitations, but taking the requirements discussed in the thesis into consideration we believe that systems developed based on the eHISS experiences in future can make a real impact on health service delivery and disease response

    The development of augmented reality glasses is still ongoing and faces barriers in diffusion and concerns about their impact on users, organizations and society. The study aims to find sufficient solutions for this struggling digital innovation and to provide guidance for the implementation of augmented reality glasses in design-oriented projects. During a 3-year consortium research, acceptance and privacy have been identified as major phenomena that influence the adoption of augmented reality glasses in the logistics domain. To forge ahead digital innovation research, the focus of the presented research lies on the diffusion of this technology with design knowledge for the development of augmented reality glasses-based systems. Evidence and artifacts contribute to the still limited knowledge of system design based on augmented reality glasses from a domain-specific instantiation and an implementation framework

    Recent advances of HCI in decision-making tasks for optimized clinical workflows and precision medicine.

    The ever-increasing amount of biomedical data is enabling new large-scale studies, even though ad hoc computational solutions are required. The most recent Machine Learning (ML) and Artificial Intelligence (AI) techniques have been achieving outstanding performance and an important impact in clinical research, aiming at precision medicine, as well as improving healthcare workflows. However, the inherent heterogeneity and uncertainty in the healthcare information sources pose new compelling challenges for clinicians in their decision-making tasks. Only the proper combination of AI and human intelligence capabilities, by explicitly taking into account effective and safe interaction paradigms, can permit the delivery of care that outperforms what either can do separately. Therefore, Human-Computer Interaction (HCI) plays a crucial role in the design of software oriented to decision-making in medicine. In this work, we systematically review and discuss several research fields strictly linked to HCI and clinical decision-making, by subdividing the articles into six themes, namely: Interfaces, Visualization, Electronic Health Records, Devices, Usability, and Clinical Decision Support Systems. However, these articles typically present overlaps among the themes, revealing that HCI inter-connects multiple topics. With the goal of focusing on HCI and design aspects, the articles under consideration were grouped into four clusters. The advances in AI can effectively support the physicians' cognitive processes, which certainly play a central role in decision-making tasks because the human mental behavior cannot be completely emulated and captured; the human mind might solve a complex problem even without a statistically significant amount of data by relying upon domain knowledge. For this reason, technology must focus on interactive solutions for supporting the physicians effectively in their daily activities, by exploiting their unique knowledge and evidence-based reasoning, as well as improving the various aspects highlighted in this review

    The state of web accessibility for people with cognitive disabilities: a rapid evidence assessment

    Get PDF
    Increased digitisation of day-to-day activities was occurring prior to the COVID-19 pandemic. The pandemic only accelerated the virtual shift, making web accessibility an urgent issue, especially for marginalised populations. Despite decades of work to develop, refine, and implement web accessibility standards, people with cognitive disabilities regularly experience many barriers to web accessibility. To inform ongoing work to improve web accessibility for people with cognitive disabilities, a systematic review was conducted. The main question guiding this review is: what are the state-of-the-art of interventions that support web accessibility for citizens, 9 years of age and up, living with cognitive impairment? A set of 50 search strings were entered into three academic databases: SCOPUS, ProQuest, and Web of Science. Systematic screening procedures narrowed the search returns to a total of 45 included papers. A data analysis revealed themes associated with the lived experiences of people with cognitive disabilities, tools for improving web accessibility, and methodological best practices for involving people with cognitive disabilities in research. These findings have immediate implications for ongoing research and the development of meaningful solutions to the problem of web accessibility for people with cognitive disabilities.info:eu-repo/semantics/publishedVersio

    Background Diabetes mellitus is a common chronic disease and a leading cause of morbidity, complications and mortality worldwide. The number of people living with diabetes is projected to rise sharply over the forthcoming decades. Diabetes care is complex and can overburden clinicians and nurses. There is a need for innovative, flexible and cost-effective technologies to enable successful diabetes management. This thesis explores the opportunities and challenges of the mobile application (app) technology as a potential tool to support diabetes care and management. Purpose The purpose was to develop and evaluate a mobile app that supports healthcare professionals (HCPs) in clinical decision-making. Methods A mixed-methods approach was used following the user-centred design (UCD) framework for the design and implementation of all studies. Quantitative and qualitative systematic reviews of studies reporting the use of mobile apps to support diabetes management were undertaken to identify, appraise and summarise available research evidence. An interview study was carried out with diabetes specialist nurses (DSNs), to explore their experiences and views, and to identify user requirements for apps. Lastly, a guidelines-based mobile clinical decision-support app was developed and tested with junior doctors and DSNs in a controlled environment to evaluate its usability and impact on adherence to clinical guidelines, and to explore how participants experienced the app and their suggestions for improvements. Results Both reviews found that the existing evidence base for mobile apps is weak and inadequate to draw conclusions about the impact of their use as interventions in diabetes management. The interview study identified that nurses lack experience in using apps in clinical practice, even though they believed it could facilitate and support their work. ‘Diabetes & CKD’, a simple mobile decision-support app, has been designed and built for the study to assist HCPs in management of patients with diabetes and kidney disease and was tested by 39 junior doctors and 3 DSNs. It had no impact on the accuracy of decisions. Feedback from participants after the pilot session and usability testing indicated a wish to integrate such apps into their clinical practice with a strong willingness to use them in the future. Conclusions Application of UCD methods was efficient as the app was well-accepted by both DSNs and junior doctors. Despite the positive views and the strong willingness to use such apps, they are not widely used. There is a need to regulate the use of medical apps in clinical practice. Further research with rigorous methodology is required upon which policymakers and practitioners can base their decision-making

    A framework to evaluate user experience of end user application security features

    The use of technology in society moved from satisfying the technical needs of users to giving a lasting user experience while interacting with the technology. The continuous technological advancements have led to a diversity of emerging security concerns. It is necessary to balance security issues with user interaction. As such, designers have adapted to this reality by practising user centred design during product development to cater for the experiential needs of user - product interaction. These User Centred Design best practices and standards ensure that security features are incorporated within End User Programs (EUP). The primary function of EUP is not security, and interaction with security features while performing a program related task does present the end user with an extra burden. Evaluation mechanisms exist to enumerate the performance of the EUP and the user’s experience of the product interaction. Security evaluation standards focus on the program code security as well as on security functionalities of programs designed for security. However, little attention has been paid to evaluating user experience of functionalities offered by embedded security features. A qualitative case study research using problem based and design science research approaches was used to address the lack of criteria to evaluate user experience with embedded security features. User study findings reflect poor user experience with EUP security features, mainly as a result of low awareness of their existence, their location and sometimes even of their importance. From the literature review of the information security and user experience domains and the user study survey findings, four components of the framework were identified, namely: end user characteristics, information security, user experience and end user program security features characteristics. This thesis focuses on developing a framework that can be used to evaluate the user experience of interacting with end user program security features. The framework was designed following the design science research method and was reviewed by peers and experts for its suitability to address the problem. Subject experts in the fields of information security and human computer interaction were engaged, as the research is multidisciplinary. This thesis contributes to the body of knowledge on information security and on user experience elements of human computer interaction security regarding how to evaluate user experience of embedded InfoSec features. The research adds uniquely to the literature in the area of Human Computer Interaction Security evaluation and measurement in general, and is specific to end user program security features. The proposed metrics for evaluating UX of interacting with EUP security features were used to propose intervention to influence UX in an academic setup. The framework, besides presenting UX evaluation strategies for EUP security features, also presents a platform for further academic research on human factors of information security. The impact can be evaluated by assessing security behaviour, and successful security breaches, as well as user experience of interaction with end user programs

    Usability analysis of contending electronic health record systems

    In this paper, we report measured usability of two leading EHR systems during procurement. A total of 18 users participated in paired-usability testing of three scenarios: ordering and managing medications by an outpatient physician, medicine administration by an inpatient nurse and scheduling of appointments by nursing staff. Data for audio, screen capture, satisfaction rating, task success and errors made was collected during testing. We found a clear difference between the systems for percentage of successfully completed tasks, two different satisfaction measures and perceived learnability when looking at the results over all scenarios. We conclude that usability should be evaluated during procurement and the difference in usability between systems could be revealed even with fewer measures than were used in our study. © 2019 American Psychological Association Inc.
