Evaluating Extended Reality Application for a Virtual Museum. Case Study: Remigio Crespo Museum

The COVID-19 pandemic was the main reason why many organisations decided to include information and communication technologies in their processes to allow them to continue with their activities, be it providing services to users (food, medicine, etc.), training/education or disseminating culture. In the field of culture, some museums incorporated technology into their operating environment, moving from face-to-face visits to virtual visits. However, in many museums, the lack of apps designed to solve the problem of virtual visits caused some to stop receiving visitors during the pandemic. In this context, this paper describes the development of an application with a user-centred design that incorporates extended reality to allow virtual visits to the Remigio Crespo Museum in the city of Cuenca (Ecuador). The evaluation carried out to verify the application's usability and learnability is also included. The results obtained indicate that users/visitors found the application usable and easy to learn. © 2022 IEEE.

True or false? Cognitive load when reading COVID-19 news headlines: An eye-tracking study

Misinformation is an important topic in the Information Retrieval (IR) context and has implications for both system-centered and user-centered IR. While it has been established that the performance in discerning misinformation is affected by a person's cognitive load, the variation in cognitive load in judging the veracity of news is less understood. To understand the variation in cognitive load imposed by reading news headlines related to COVID-19 claims, within the context of a fact-checking system, we conducted a within-subject, lab-based, quasi-experiment (N=40) with eye-tracking. Our results suggest that examining true claims imposed a higher cognitive load on participants when news headlines provided incorrect evidence for a claim and were inconsistent with the person's prior beliefs. In contrast, checking false claims imposed a higher cognitive load when the news headlines provided correct evidence for a claim and were consistent with the participants' prior beliefs. However, changing beliefs after examining a claim did not have a significant relationship with cognitive load while reading the news headlines. The results illustrate that reading news headlines related to true and false claims in the fact-checking context impose different levels of cognitive load. Our findings suggest that user engagement with tools for discerning misinformation needs to account for the possible variation in the mental effort involved in different information contexts. © 2023 ACM.

Experience of Students in Using Online Mental Health Interventions: A Qualitative Study

Online mental health interventions have been posited as a way to reduce the mental health treatment gap among students in higher education. The effectiveness of these interventions is often limited by low user adherence. A potential solution is to improve user adherence by producing user-centred interventions. A total of 452 students from University College Cork, Ireland participated in the survey, "Tell us About Your Mental Health Post-COVID-19”. The survey examined students' mental health over the past year, their use of technological supports, their use of mental health support services and their ratings of mental health support services used. This study explores students' experiences with technological support. The thematic analysis of 138 open-ended responses produced seven main themes: 1) Appeal 2) Barriers to Use 3) Discovery 4) Drawbacks 5) Purpose 6) Reasons for Stopping and 7) Usage Patterns. The results of this study revealed students' openness to using online mental health resources. It also revealed the barriers and facilitators to their use of these resources. Finally, based on our findings, we provide recommendations to researchers/designers developing online mental health interventions for university students. Some of these recommendations were to ensure safety in online communities, provide good user interfaces, support students in crises and improve the accessibility of online resources to students with learning disabilities. © 2023, The Author(s), under exclusive license to Springer Nature Switzerland AG.

Transferring AI Explainability to User-Centered Explanations of Complex COVID-19 Information

This paper presents a user-centered approach to translating techniques and insights from AI explainability research to developing effective explanations of complex issues in other fields, on the example of COVID-19. We show how the problem of AI explainability and the explainability problem in the COVID-19 pandemic are related: as two specific instances of a more general explainability problem, occurring when people face in-transparent, complex systems and processes whose functioning is not readily observable and understandable to them ("black boxes”). Accordingly, we discuss how we applied an interdisciplinary, user-centered approach based on Design Thinking to develop a prototype of a user-centered explanation for a complex issue regarding people's perception of COVID-19 vaccine development. The developed prototype demonstrates how AI explainability techniques can be adapted and integrated with methods from communication science, visualization and HCI to be applied to this context. We also discuss results from a first evaluation in a user study with 88 participants and outline future work. The results indicate that it is possible to effectively apply methods and insights from explainable AI to explainability problems in other fields and support the suitability of our conceptual framework to inform that. In addition, we show how the lessons learned in the process provide new insights for informing further work on user-centered approaches to explainable AI itself. © 2022, The Author(s).

Proposal for a User-Centered Virtual Reality System for Promoting Tourism in Peru

Tourism has a substantial impact on the economy of different regions of the world such as Latin America, however due to the health crisis generated by COVID-19 this sector has been one of the most affected, for this reason, different investigations have been carried out focused on solving the problems generated by the pandemic. Therefore, it has become necessary to implement new technological alternatives that allow promoting alternative tourism;for example, take virtual tours of different tourist attractions with the help of virtual or augmented reality. In this article we present a proposal for a virtual reality application focused on promoting tourism in Peru using a user-centered design. To make this proposal, an analysis of tourism in Peru was carried out, analyzing the impact of the pandemic in Peru and the most visited attractions in the city of Arequipa to select the scenarios to be virtualized. An important aspect of the proposed is the creation of a user-centered design, for which a set of functions focused on users was proposed, such as the use of a map to select the tourist attractions to visit, showing updated information of the tourist attractions, the use of multiple methods of movement in virtual reality environments and a camera that allows taking pictures when navigating the virtual scenario. © 2022, Springer Nature Switzerland AG.

Research Proposal: A Telehealth and Sensor-Based System for User-Centered Physical Therapy in Parkinson's Disease

This paper contains the research proposal of Samantha O'Sullivan that was presented at the MMSys 2022 doctoral symposium. The use of wearable sensors for the understanding and quantification of movement within research communities working on Parkinson's Disease (PD) has increased significantly in recent years with a motivation to objectively diagnose, assess and then understand the progression of the disease. Most studies taking this approach for PD have stated that there is a need for a long-term solution, due to varying symptoms at different stages of the disease. COVID-19 has brought further limitations in the delivery of clinical care, reducing time with therapists and doctors whilst increasing the preference for at-home care. The necessity for a system for patients with PD is extremely significant. There is no clinically available long-term assessment for tremors, which is an issue highlighted in the literature. By using wireless sensors to track tremor severity continuously, and telehealth to create communication between patient and clinician, this proposed system will allow for better targeted therapy, accurate statistics, and constant accessible data. In this context, this work will design, build, and evaluate a novel system that would allow for constant monitoring of a patient with tremors. By using wireless sensors and telehealth, it will provide more detailed data that may enable directed and informed physical therapy. It will also improve communication creating a data flow constantly between clinician and patient to improve person-centered feedback, and aid towards the diagnosis and assessment of disease progression. The incorporation of a mobile/cloud-based application to assist this is due to the current heightened preference for home-based healthcare, long-term evaluation of tremors and personalized physical therapy. The primary focus of the PhD will be on capturing tremor activity and progression through a telehealth-based system. This proposed system will obtain real-time readings of tremors using wireless sensors and an application that will communicate consistently with healthcare professionals. The aim will be to provide better home-based care, person-centered physical therapy and improve quality of life. © 2022 ACM.

A Biofeedback-Based Mobile App With Serious Games for Young Adults With Anxiety in the United Arab Emirates: Development and Usability Study.

BACKGROUND: Following the outbreak of COVID-19, several studies have reported that young adults encountered a rise in anxiety symptoms, which could negatively affect their quality of life. Promising evidence suggests that mobile apps with biofeedback, serious games, breathing exercises, and positive messaging, among other features, are useful for anxiety self-management and treatment. OBJECTIVE: This study aimed to develop and evaluate the usability of a biofeedback-based app with serious games for young adults with anxiety in the United Arab Emirates (UAE). METHODS: This study consists of two phases: Phase I describes the design and development of the app, while Phase II presents the results of a usability evaluation by experts. To elicit the app's requirements during Phase I, we conducted (1) a survey to investigate preferences of young adults in the UAE for mobile games for stress relief; (2) an analysis of serious games for anxiety; and (3) interviews with mental health professionals and young adults in the UAE. In Phase II, five experts tested the usability of the developed app using a set of Nielsen's usability heuristics. RESULTS: A fully functional biofeedback-based app with serious games was co-designed with mental health professionals. The app included 4 games (ie, a biofeedback game, card game, arcade game, and memory game), 2 relaxation techniques (ie, a breathing exercise and yoga videos), and 2 additional features (ie, positive messaging and a mood tracking calendar). The results of Phase II showed that the developed app is efficient, simple, and easy to use. Overall, the app design scored an average of 4 out of 5. CONCLUSIONS: The elicitation techniques used in Phase I resulted in the development of an easy-to-use app for the self-management of anxiety. Further research is required to determine the app's usability and effectiveness in the target population.

Design Implications for Interactive and Analogue Technologies supporting Distance Education: A Longitudinal Mixed-Method Study during the Pandemic

This study investigates COVID-19's impact on the education system by gathering data on how interactive and analogue technologies mitigated such disruption. It also analyses how and if educational approaches were modified during the pandemic. The procedures consisted of the analysis of evidence retrieved from three surveys delivered to three stakeholder groups: teachers, students, and parents (N=215), crossed with an examination of a set of 5-week longitudinal interviews (30) with the same groups (N=6). The results of the analysis are used to derive a set of important design implications that: (1) highlight shortcomings of the distance education (DE) strategies used during COVID-19 and how they can be mitigated;(2) empower the stakeholders with innovative pedagogical approaches that information communication technologies can foster, thus optimising DE;(3) promotes positive learning experiences supported with scientific evidence. Conclusions are derived from a collaborative reflection on the stakeholders' daily needs during unpredictable circumstances.

Designing energy solutions: a comparison of two participatory design approaches for service innovation

Purpose>Participatory design involves users and other key stakeholders in processes that aim to ensure solutions generated meet their needs. This paper compares the processes and outcomes of two participatory design approaches (design thinking and co-design) to examine their utility in co-creating innovative service solutions for reducing household energy demand.Design/methodology/approach>Design thinking and co-design were implemented in two independent convenience samples of household energy users in Queensland, Australia. Workshops were conducted online using Zoom and Padlet technology. Informed by the capability-practice-ability (CPA) portfolio, a critical analysis based on the research team's experiences with implementing the two participatory design approaches is presented.Findings>The key distinguishing features that set design thinking apart from co-design is extent of user involvement, solution diversity and resource requirements. With a shorter duration and less intensive user involvement, co-design offers a more resource efficient means of solution generation. In contrast, design thinking expands the solution space by allowing for human-centred problem framing and in so doing gives rise to greater diversity in solutions generated.Research limitations/implications>Mapping the six constellations of service design outlined in the CPA portfolio to the research team's experiences implementing two different participatory design approaches within the same context reconciles theoretical understanding of how capabilities, practices and abilities may differ or converge in an applied setting.Practical implications>Understanding the benefits and expected outcomes across the two participatory design approaches will guide practitioners and funding agencies in the selection of an appropriate method to achieve desired outcomes.Originality/value>This paper compares two forms of participatory design (design thinking and co-design) for service innovation in the context of household energy demand offering theoretical and practical insights into the utility of each as categorised within the CPA portfolio.

User-Centered Design of A Novel Risk Prediction Behavior Change Tool Augmented With an Artificial Intelligence Engine (MyDiabetesIQ): A Sociotechnical Systems Approach.

BACKGROUND: Diabetes and its complications account for 10% of annual health care spending in the United Kingdom. Digital health care interventions (DHIs) can provide scalable care, fostering diabetes self-management and reducing the risk of complications. Tailorability (providing personalized interventions) and usability are key to DHI engagement/effectiveness. User-centered design of DHIs (aligning features to end users' needs) can generate more usable interventions, avoiding unintended consequences and improving user engagement. OBJECTIVE: MyDiabetesIQ (MDIQ) is an artificial intelligence engine intended to predict users' diabetes complications risk. It will underpin a user interface in which users will alter lifestyle parameters to see the impact on their future risks. MDIQ will link to an existing DHI, My Diabetes My Way (MDMW). We describe the user-centered design of the user interface of MDIQ as informed by human factors engineering. METHODS: Current users of MDMW were invited to take part in focus groups to gather their insights about users being shown their likelihood of developing diabetes-related complications and any risks they perceived from using MDIQ. Findings from focus groups informed the development of a prototype MDIQ interface, which was then user-tested through the "think aloud" method, in which users speak aloud about their thoughts/impressions while performing prescribed tasks. Focus group and think aloud transcripts were analyzed thematically, using a combination of inductive and deductive analysis. For think aloud data, a sociotechnical model was used as a framework for thematic analysis. RESULTS: Focus group participants (n=8) felt that some users could become anxious when shown their future complications risks. They highlighted the importance of easy navigation, jargon avoidance, and the use of positive/encouraging language. User testing of the prototype site through think aloud sessions (n=7) highlighted several usability issues. Issues included confusing visual cues and confusion over whether user-updated information fed back to health care teams. Some issues could be compounded for users with limited digital skills. Results from the focus groups and think aloud workshops were used in the development of a live MDIQ platform. CONCLUSIONS: Acting on the input of end users at each iterative stage of a digital tool's development can help to prioritize users throughout the design process, ensuring the alignment of DHI features with user needs. The use of the sociotechnical framework encouraged the consideration of interactions between different sociotechnical dimensions in finding solutions to issues, for example, avoiding the exclusion of users with limited digital skills. Based on user feedback, the tool could scaffold good goal setting, allowing users to balance their palatable future complications risk against acceptable lifestyle changes. Optimal control of diabetes relies heavily on self-management. Tools such as MDMW/ MDIQ can offer personalized support for self-management alongside access to users' electronic health records, potentially helping to delay or reduce long-term complications, thereby providing significant reductions in health care costs.

Designing An Attendance System Model for Work from Home (WFH) Employees Based on User-Centered

Attendance system has evolved along with the industrial revolution that now has reached a new era. Furthermore, nowadays with the struck of COVID-19, the government issued a prohibition policy towards companies to urge their employees to work from home (WFH). Several issues have come across the Human Resources Development (HRD) manager regarding this policy. Employees' taking vacation when they are obliged to work from home and employees' faking their attendance are two of many problems regarding this policy. Hence, this study aims to design a relevant attendance system model that will overcome these problems with the integration of face recognition and geolocation through mobile platform. The study built the proposed attendance system with the approach of User-Centered Design (UCD) methodology. The findings within the study shows that above 80% of participants are satisfied with the proposed model and are ready to implement the designed system in their organizations respectively. © 2021 IEEE.

Loneliness in older people and COVID-19: Applying the social identity approach to digital intervention design.

The COVID-19 pandemic is worsening loneliness for many older people through the challenges it poses in engaging with their social worlds. Digital technology has been offered as a potential aid, however, many popular digital tools have not been designed to address the needs of older adults during times of limited contact. We propose that the Social Identity Model of Identity Change (SIMIC) could be a foundation for digital loneliness interventions. While SIMIC is a well-established approach for maintaining wellbeing during life transitions, it has not been rigorously applied to digital interventions. There are known challenges to integrating psychological theory in the design of digital technology to enable efficacy, technology acceptance, and continued use. The interdisciplinary field of Human Computer Interaction has a history of drawing on models originating from psychology to improve the design of digital technology and to design technologies in an appropriate manner. Drawing on key lessons from this literature, we consolidate research and design guidelines for multidisciplinary research applying psychological theory such as SIMIC to digital social interventions for loneliness.

A Proposed Framework for Developing User-Centred Mobile Healthcare Applications for the Biggest Annual Mass Gathering (Hajj) Post COVID-19

The Hajj pilgrimage being the largest annual mass gathering globally with two to three million participants from over 180 counties, will remain a high priority for diseases surveillance for future epidemics or any other international public health emergencies with rapid scalability. This paper highlights the importance of monitoring mass gatherings during a pandemic and how mHealth applications can reduce the burden on health facilities during a mass gathering and tackle future infectious diseases outbreaks. The paper also highlights the importance of developing a user-centred application when designing for a diverse group of users with a shared purpose. As a result, a framework has been proposed to update the current applications or design and develop future mobile health applications. The framework has been developed based on the rationale and evidence found in the literature. © Islam et al. Published by BCS Learning and Development Ltd.

Digitally Enabled Health Service for the Integrated Management of Hypertension: A Participatory User-Centred Design Process.

This article describes a user-centred approach taken by a group of five procurers to set specifications for the procurement of value-based research and development services for IT-supported integrated hypertension management. The approach considered the unmet needs of patients and health systems of the involved regions. The procurers established a framework for requirements and a solution design consisting of nine building blocks, divided into three domains: service delivery, devices and integration, and health care organisation. The approach included the development of questionnaires, capturing patients' and professionals' views on possible system functionalities, and a template collecting information about the organisation of healthcare, professionals involved and existing IT systems at the procurers' premises. A total of 28 patients diagnosed with hypertension and 26 professionals were interviewed. The interviewees identified 98 functional requirements, grouped in the nine building blocks. A total of nine use cases and their corresponding process models were defined by the procurers' working group. As result, a digitally enabled integrated approach to hypertension has been designed to allow citizens to learn how to prevent the development of hypertension and lead a healthy lifestyle, and to receive comprehensive, individualised treatment in close collaboration with healthcare professionals.

Conversations that count: Lessons from evaluating a men's digital mental health response during COVID-19.

This paper details disruption and innovation in digital evaluation practice at Movember, as a result of the COVID-19 pandemic. The paper examines a men's digital health intervention (DHI) - Movember Conversations - and the product pivot that was necessary to ensure it could respond to the pandemic. The paper focuses on the implications of the pivot for the evaluation and how the evaluation was adapted to the COVID-19 exigencies. It details the redesign of the evaluation to ensure methods wrapped around the modified product and could deliver real-time, practical insights. The paper seeks to fill knowledge gaps in the DHI evaluation space and outlines four key principles that support evaluation re-design in an agile setting. These include a user-centred approach to evaluation design, proportionate data collection, mixed (and flexible) methodologies, and agile evaluation reporting. The paper concludes with key lessons and reflections from the evaluators about what worked at Movember, to support other evaluators planning digital evaluations.

User-Centred Design of a Digital Care Plan for Patients and Professionals in Cross-Organisational Teams.

Care for patients with multimorbidity and long-term complex needs is costly and with demographic changes this group is growing. The research project Dignity Care addresses how to improve the care for this patient group by studying how a conceptual shared digital care plan for complex clinical pathways can guide and support cross-organisational care teams. This paper presents the user-centred design process for the digital care plan development. Panels of patients and health care professionals will participate in co-creation user workshops and simulation of complex patients' pathways. The main contribution from this work is recommendations for how to actively involve user groups in digital health development, applying a partly remote approach of user-centred design methodology during the Covid-19 pandemic.

User-Centred Design with a Remote Approach: Experiences from the Chronic Pain Project.

User-centred design involves end-users or user groups during all the parts of the development process. The research project Chronic Pain aims to develop a shared decision making application for patients and physicians, addressing individually adapted pain treatment. The project employs a user-centred design process, and in middle of it, Covid-19 pandemic social distancing restrictions were imposed. This paper presents how the user-centred design process together with a patient organisation was transformed to a digital approach and the experiences from performing a remote co-creation user workshop. The digital approximation had a satisfactory result and the main contribution lies in the sharing of recommendations for how to practically apply a remote user-centred design methodology.
