This study explores the design of intelligent water dispensers for young rental housing groups to meet their needs for convenience, instant water supply, and energy efficiency. With the acceleration of urbanization and the increase in youth mobility, traditional drinking water solutions can no longer fully meet the needs of this group. Through literature research, questionnaire surveys, and user and expert interviews, this article comprehensively analyzes the market demand, user preferences, and user experience of smart water dispensers. Research has found that young users prefer smart water dispensers that are hot, energy-efficient, and easy to operate, while also having high expectations for product appearance design and technological innovation. Based on the research results, this article proposes a user centered design strategy, aiming to improve user experience and enhance product market competitiveness by optimizing the design elements of intelligent water dispensers at the instinctive, behavioral, and reflective levels. This study provides theoretical support and practical guidance for the product innovation and market strategy of intelligent water dispensers.

Older adults’ intention to use voice assistants: Usability and emotional needs

Population aging is a global problem, and improving the well-being of older adults is an urgent issue. Voice assistants (VAs) offer hands-free voice control and friendly human-computer interaction, making them a significant solution to address the aging problem. Most extant research on VAs is fragmented, and there are relatively few studies conducted from the perspective of emotional needs. This work proposes a comprehensive research model extending the technology acceptance model (TAM) by incorporating the influencing factors subordinate to two research directions: usability and emotional needs. Usability needs include three factors: perceived convenience, security/privacy, and Internet self-efficacy. Emotional needs include humanized interaction, perceived enjoyment, and perceived companionship. A structural equation model (SEM) was used to validate the model empirically with a sample of 425 older users of VAs. The analysis results are quite consistent with the research assumptions, and the findings illustrate that companionship is the most critical factor affecting older adults' intention to adopt VA use, which demonstrates the pivotal role of VAs in meeting the emotional needs of the elderly. The most unexpected observation was seen for the relationship between perceived ease of use and behavioral intention, which was non-significant. This result confirms that when a technology is perceived as very easy to use, perceived ease of use has little to no impact on individuals' intention to use that technology. The novelty of this study lies in the investigation of older adults' behavioral intentions toward using VAs, providing valuable insights for the design and development of VAs tailored for the elderly population. Beyond the academic realm, this research serves as direct inspiration for designers, developers, and policymakers in the fields of assistive technologies and geriatric care. It offers practical insights into creating VAs that effectively address the emotional needs of older adults and enhance their quality of life. Furthermore, elderly individuals are poised to experience significant benefits from the outcomes of this study，the insights garnered from this study empower the elderly to embrace technological advancements that align with their preferences and comfort levels. This study contributes to a more comprehensive understanding of VAs and their potential to enhance the well-being of older adults, while also paving the way for future investigations in this domain. As underscored by this study's emphasis on the significance of emotional needs in technology acceptance, it encourages the adoption of more user-centered design strategies in the development of future VAs.

Review of strategies to investigate low sample return rates in remote tobacco trials: A call to action for more user-centered design research

Remote collection of biomarkers of tobacco use in clinical trials poses significant challenges. A recent meta-analysis and scoping review of the smoking cessation literature indicated that sample return rates are low and that new methods are needed to investigate the underlying causes of these low rates. In this paper we conducted a narrative review and heuristic analysis of the different human factors approaches reported to evaluate and/or improve sample return rates among 31 smoking cessation studies recently identified in the literature. We created a heuristic metric (with scores from 0 to 4) to evaluate the level of elaboration or complexity of the user-centered design strategy reported by researchers. Our review of the literature identified five types of challenges typically encountered by researchers (in that order): usability and procedural, technical (device related), sample contamination (e.g., polytobacco), psychosocial factors (e.g., digital divide), and motivational factors. Our review of strategies indicated that 35% of the studies employed user-centered design methods with the remaining studies relying on informal methods. Among the studies that employed user-centered design methods, only 6% reached a level of 3 in our user-centered design heuristic metric. None of the studies reached the highest level of complexity (i.e., 4). This review examined these findings in the context of the larger literature, discussed the need to address the role of health equity factors more directly, and concluded with a call to action to increase the application and reporting of user-centered design strategies in biomarkers research.

User-centered Design Strategies to Develop Mobile Application for Selection of Digital Forensics Tool

There are several types of digital forensics tool. Therefore, to help investigators to choose suitable tools, a recommendation system is needed. This research type is development of mobile application recommendation system. The development using User Centered Design (UCD) method. The evaluation system uses the Blackbox method and the User Acceptance Test (UAT) method. From the results, it is concluded that the application is useful, easy to use, and easy to learn by users. As for usability testing, it was found that the users found it very helpful to operate, which was 28 students with a margin of error of 5%.

Development of a Dynamically Tailored mHealth Intervention (What Do You Drink) to Reduce Excessive Drinking Among Dutch Lower-Educated Students: User-Centered Design Approach.

BackgroundThe high prevalence and adverse consequences of excessive drinking among lower-educated adolescents and young adults are public concerns in the Netherlands. Evidence-based alcohol prevention programs targeting adolescents and young adults with a low educational background are sparse.ObjectiveThis study aimed to describe the planned process for the theory- and evidence-based development, implementation, and evaluation of a dynamically tailored mobile alcohol intervention, entitled What Do You Drink (WDYD), aimed at lower-educated students from secondary vocational education and training (Middelbaar Beroepsonderwijs in Dutch).MethodsWe used intervention mapping as the framework for the systematic development of WDYD. It consists of the following six steps: assessing needs (step 1), formulating intervention objectives (step 2), translating theoretical methods into practical applications (step 3), integrating these into a coherent program (step 4), anticipating future implementation and adoption (step 5), and developing an evaluation plan (step 6).ResultsReducing excessive drinking among Dutch lower-educated students aged 16 to 24 years was defined as the desired behavioral outcome and subdivided into the following five program objectives: make the decision to reduce drinking, set realistic drinking goals, use effective strategies to achieve drinking goals, monitor own drinking behavior, and evaluate own drinking behavior and adjust goals. Risk awareness, motivation, social norms, and self-efficacy were identified as the most important and changeable individual determinants related to excessive drinking and, therefore, were incorporated into WDYD. Dynamic tailoring was selected as the basic intervention method for changing these determinants. A user-centered design strategy was used to enhance the fit of the intervention to the needs of students. The intervention was developed in 4 iterations, and the prototypes were subsequently tested with the students and refined. This resulted in a completely automated, standalone native app in which students received dynamically tailored feedback regarding their alcohol use and goal achievement via multiple sessions within 17 weeks based on diary data assessing their alcohol consumption, motivation, confidence, and mood. A randomized controlled trial with ecological momentary assessments will be used to examine the effects, use, and acceptability of the intervention.ConclusionsThe use of intervention mapping led to the development of an innovative, evidence-based intervention to reduce excessive alcohol consumption among lower-educated Dutch adolescents and young adults. Developing an intervention based on theory and empirical evidence enables researchers and program planners to identify and retain effective intervention elements and to translate the intervention to new populations and settings. This is important, as black boxes, or poorly described interventions, have long been a criticism of the eHealth field, and effective intervention elements across mobile health alcohol interventions are still largely unknown.Trial RegistrationNetherlands Trial Registry NTR6619; https://trialsearch.who.int/Trial2.aspx?TrialID=NTR6619

Reviewing the User-Centered Design Process for a Comprehensive Gastroesophageal Reflux Disease (GERD) App.

The objective of this study was to design a user-centered mobile health (mHealth) application for individuals with gastroesophageal reflux disease (GERD) and evaluate its design features and effectiveness for use by doctors. Prior to designing, our team undertook a discovery process that involved creating personas, conducting a competitor analysis and heuristic evaluation of existing apps, along with interviews with acid reflux patients. Then, we created a low-fidelity prototype, which was revised on the basis of several rounds of user testing. During the design phase, each round of user testing included a mix of surveys, concurrent think-alouds, and interviews to gather user feedback on the prototypes. Lastly, an evaluation phase consisting of gathering feedback on the user-centered design approach from user experience experts and medical doctors specialized in GERD was conducted. Overall, the final GERD app includes important features for tracking symptoms and triggers, analytics, data export, and community information, while promoting individualization, accessibility, and usability. The documentation of the design process of this app serves as a reference point for future medical app developers as it followed an empirically supported user-centered design strategy and resulted in an app which received positive feedback from users and human factors experts. We also intend to share some of the limitations due to the constrained resources, as well as potential ways to strengthen the design process for mHealth applications.

Development and Implementation of a Multidisciplinary Electronic Discharge Readiness Tool: User-Centered Design Approach.

BackgroundTypical solutions for improving discharge planning often rely on one-way communication mechanisms, static data entry into the electronic health record (EHR), or in-person meetings. Lack of timely and effective communication can adversely affect patients and their care teams.ObjectiveApplying robust user-centered design strategies, we aimed to design an innovative EHR-based discharge readiness communication tool (the Discharge Today tool) to enable care teams to communicate any barriers to discharge, the status of patient discharge readiness, and patient discharge needs in real time across hospital settings.MethodsWe employed multiple user-centered design strategies, including exploration of the current state for documenting discharge readiness and directing discharge planning, iterative low-fidelity prototypes, multidisciplinary stakeholder meetings, a brainwriting premortem exercise, and preproduction user testing. We iteratively collected feedback from users via meetings and surveys.ResultsWe conducted 28 meetings with 20 different stakeholder groups. From these stakeholder meetings, we developed 14 low-fidelity prototypes prior to deploying the Discharge Today tool for our pilot study. During the pilot study, stakeholders requested 46 modifications, of which 25 (54%) were successfully executed. We found that most providers who responded to the survey reported that the tool either saved time or did not change the amount of time required to complete their discharge workflow (21/24, 88%). Responses to open-ended questions offered both positive feedback and opportunities for improvement in the domains of efficiency, integration into workflow, avoidance of redundancies, expedited communication, and patient-centeredness.ConclusionsSurvey data suggest that this electronic discharge readiness tool has been successfully adopted by providers and clinical staff. Frequent stakeholder engagement and iterative user-centered design were critical to the successful implementation of this tool.

Understanding the Methodological Issues and Solutions in the Research Design of Stroke Caregiving Technology.

The rise in the number of cases of stroke has resulted in a significant burden on the healthcare system. As a result, the majority of care for the person living with stroke occurs within the community, resulting in caregivers being a central and challenged agent in care. To better support caregivers during the recovery trajectory poststroke, we investigated the role of health technologies to promote education and offer various kinds of support. However, the introduction of any new technology comes with challenges due to the growing need for more user-centric systems. The integration of user-centric systems in stroke caregiving has the potential to ensure long-term acceptance, success, and engagement with the technology, thereby ensuring better care for the person living with stroke. We first briefly characterize the affordances of available technologies for stroke caregiving. We then discuss key methodological issues related to the acceptance to such technologies. Finally, we suggest user-centered design strategies for mitigating such challenges.

Aligning implementation and user-centered design strategies to enhance the impact of health services: results from a concept mapping study

BackgroundInnovative approaches are needed to maximize fit between the characteristics of evidence-based practices (EBPs), implementation strategies that support EBP use, and contexts in which EBPs are implemented. Standard approaches to implementation offer few ways to address such issues of fit. We characterized the potential for collaboration with experts from a relevant complementary approach, user-centered design (UCD), to increase successful implementation.MethodUsing purposive and snowball sampling, we recruited 56 experts in implementation (n = 34) or UCD (n = 22). Participants had 5+ years of professional experience (M = 10.31), worked across many settings (e.g., healthcare, education, human services), and were mostly female (59%) and white (73%). Each participant completed a web-based concept mapping structured conceptualization task. They sorted strategies from established compilations for implementation (36 strategies) and UCD (30 strategies) into distinct clusters, then rated the importance and feasibility of each strategy.ResultsWe used multidimensional scaling techniques to examine patterns in the sorting of strategies. Based on conceptual clarity and fit with established implementation frameworks, we selected a final set of 10 clusters (i.e., groups of strategies), with five implementation-only clusters, two UCD-only clusters, and three trans-discipline clusters. The highest-priority activities (i.e., above-average importance and feasibility) were the trans-discipline clusters plus facilitate change and monitor change. Implementation and UCD experts sorted strategies into similar clusters, but each gave higher importance and feasibility ratings to strategies/clusters from their own discipline.ConclusionsIn this concept mapping study, experts in implementation and UCD had perspectives that both converged (e.g., trans-discipline clusters, which were all rated as high-priority) and diverged (e.g., in importance/feasibility ratings). The results provide a shared understanding of the alignment between implementation science and UCD, which can increase the impact and sustainability of EBP implementation efforts. Implications for improved collaboration among implementation and UCD experts are discussed.

Trends in research participant categories and descriptions in abstracts from the International BCI Meeting series, 1999 to 2016

ABSTRACTMuch brain-computer interface (BCI) research is intended to benefit people with disabilities (PWD), though they are rarely included as study participants. When included, a range of clinical and non-clinical descriptions are used leading to difficulty interpreting and replicating results. We examined trends in inclusion and description of study participants with disabilities across six International BCI Meetings from 1999 to 2016. Meeting abstracts were analyzed by trained independent reviewers. Results suggested declines in participation by PWD across Meetings until the 2016 Meeting. Fifty-eight percent of abstracts identified PWD as end-users, though only twenty-two percent included participants with disabilities, suggesting evidence of a persistent translational gap. Increased diagnostic specificity was noted at the 2013 and 2016 Meetings. Studies often identified physical and/or communication impairments in participants with disabilities versus impairments in other areas. Implementing participatory action research principles and user-centered design strategies within BCI research is critical to bridge the translational gap.

Abstract P6-11-01: Field testing of a point-of-care decision support tool for contralateral prophylactic mastectomy

Abstract Background: The majority of women undergoing contralateral prophylactic mastectomy (CPM) overestimate their risk of developing a contralateral breast cancer and incorrectly believe the CPM will substantially improve their overall survival. Using the results of our published micro-simulation decision-analytic model (Davies et al. Breast Cancer Res, 2016), we created and tested a CPM decision support tool to provide patients and breast cancer surgeons with individualized estimates of contralateral breast cancer risk and overall mortality. Methods: The CPM decision support tool had four entry parameters from the micro-simulation model (age, family history of breast cancer, estrogen receptor status, and stage), and a visual depiction of outcomes using icon arrays for chances of developing a contralateral breast cancer and overall mortality with and without CPM. A user-centered design strategy was used with input and iterative refinement from stakeholders, i.e., breast cancer surgeons, patient advocates and breast cancer survivors. The tool was field-tested at MD Anderson Cancer Center with 5 breast cancer surgeons each using the tool with 5 breast cancer patients considering CPM (25 total). Patients completed a knowledge survey immediately before and after viewing the tool and the Decisional Conflict Scale (DCS) after viewing the tool. Surgeons completed the System Usability Scale (SUS) and ratings of the acceptability of the tool. Results: The mean age of patients was 58 years. All patients reported the tool was helpful in making a decision about CPM and would recommend it to others. Knowledge of breast cancer and key CPM facts increased from before to after using the tool (64% vs. 75%, respectively, P<0.05). The mean score on the DCS was 10.5 (standard deviation =14.3) indicating patients were overall sure about the CPM choice. The majority (72%) of patients were unsure of their interest in CPM before viewing the tool. After viewing the tool, 13 (52%) of patients indicated they did not want CPM, 4 (16%) indicated they wanted CPM, and 8 (32%) remained unsure. Surgeons rated the tool as having a positive impact on the decision-making process and SUS scores were highly favorable (mean 93 on 0-100 scale, with 100 indicating highest usability). Conclusion: The CPM decision tool had high overall patient satisfaction and improved knowledge about CPM without affecting decisional conflict. Decision support tools may be used to improve the quality of decision-making about CPM by providing surgeons and their patients with useful individualized information about CPM's impact on relevant clinical outcomes, which may lower the incidence of CPM.

A glossary of user-centered design strategies for implementation experts.

User-centered design (UCD), a discipline that seeks to ground the design of an innovation in information about the people who will ultimately use that innovation, has great potential to improve the translation of evidence-based practices from behavioral medicine research for implementation in health care settings. UCD is a diverse, innovative field that remains highly variable in terms of language and approaches. Ultimately, we produced a glossary of UCD-related strategies specifically for experts in implementation research and practice, with the goal of promoting interdisciplinary collaboration in implementation efforts. We conducted a focused literature review to identify key concepts and specific strategies of UCD to translate into the implementation field. We also categorized the strategies as primarily targeting one or more levels of the implementation process (i.e., interventions, individuals, inner context, and outer context). Ultimately, we produced a glossary of 30 UCD strategies for implementation experts. Each glossary term is accompanied by a short, yet comprehensive, definition. The strategies and their definitions are illustrated, using a hypothetical behavioral medicine intervention as an example, for each of the four levels of the implementation process. This UCD glossary may prove useful to implementation experts who wish to develop effective collaborations and "shared language" with UCD experts to enhance use of behavioral medicine research in health services. Directions for future research are also discussed.

INNUENDO: A cross‐sectoral platform for the integration of genomics in the surveillance of food‐borne pathogens

Abstract In response to the EFSA call New approaches in identifying and characterizing microbial and chemical hazards, the project INNUENDO (https://sites.google.com/site/theinnuendoproject/) aimed to design an analytical platform and standard procedures for the use of whole-genome sequencing in surveillance and outbreak investigation of food-borne pathogens. The project firstly attempted to identify existing flaws and needs, and then to provide applicable cross-sectorial solutions. The project focused in developing a platform for small countries with limited economical and personnel resources. To achieve these goals, we applied a user-centered design strategy involving the end-users, such as microbiologists in public health and veterinary authorities, in every step of the design, development and implementation phases. As a result, we delivered the INNUENDO Platform V1.0 (https://innuendo.readthedocs.io/en/latest/), a stand-alone, portable, open-source, end-to-end system for the management, analysis, and sharing of bacterial genomic data. The platform uses Nextflow workflow manager to assemble analytical software modules in species-specific protocols that can be run using a user-friendly interface. The reproducibility of the process is ensured by using Docker containers and throught the annotation of the whole process using an ontology. Several modules, available at https://github.com/TheInnuendoProject, have been developed including: genome assembly and species confirmation; fast genome clustering; in silico typing; standardized species-specific phylogenetic frameworks for Campylobacter jejuni, Yersinia enterocolitica, Salmonella enterica and Escherichia coli based on an innovative gene-by-gene methodology; quality control measures from raw reads to allele calling; reporting system; a built-in communication protocols and a strain classification system enabling smooth communication during outbreak investigation. As proof-of-concepts, the proposed solutions have been thoroughly tested in simulated outbreak conditions by several public health and veterinary agencies across Europe. The results have been widely disseminated through several channels (web-sites, scientific publications, organization of workshops). The INNUENDO Platform V1.0 is effectively one of the models for the usage of open-source software in genomic epidemiology.

Systematically Developing a Web-Based Tailored Intervention Promoting HPV-Vaccination Acceptability Among Mothers of Invited Girls Using Intervention Mapping.

Background: Currently, the eHealth field calls for detailed descriptions of theory-based interventions in order to support improved design of such interventions. This article aims to provide a systematic description of the design rationale behind an interactive web-based tailored intervention promoting HPV-vaccination acceptability.Methods: The 6-step Intervention Mapping (IM) protocol was used to describe the design rationale. After the needs assessment in Step 1, intervention objectives were formulated in Step 2. In Step 3, we translated theoretical methods into practical applications, which were integrated into a coherent intervention in Step 4. In Step 5, we anticipated future implementation and adoption, and finally, an evaluation plan was generated in Step 6.Results: Walking through the various steps of IM resulted in a detailed description of the intervention. The needs assessment indicated HPV-vaccination uptake remaining lower than expected. Mothers play the most important role in decision-making about their daughter's immunization. However, they generally feel ambivalent after they made their decisions, and their decisions are based on rather unstable grounds. Therefore, intervention objectives were to improve HPV-vaccination uptake and informed decision-making, and to decrease decisional conflict among mothers of invited girls. Computer-tailoring was chosen as the main method; virtual assistants were chosen as a practical application to deliver interactive tailored feedback. To maximize compatibility with the needs of the target group, a user-centered design strategy by means of focus groups and online experiments was applied. In these, prototypes were tested and sequentially refined. Finally, efficacy, effectiveness, and acceptability of the intervention were tested in a randomized controlled trial. Results showed a significant positive effect of the intervention on informed decision-making, decisional conflict, and nearly all determinants of HPV-vaccination uptake (P < 0.001). Mothers evaluated the intervention as highly positive.Discussion: Using IM led to an innovative effective intervention for promoting HPV-vaccination acceptability. The intervention maps will aid in interpreting the results of our evaluation studies. Moreover, it will ease the comparison of design rationales across interventions, and may provide leads for the development of other eHealth interventions. This paper adds to the plea for systematic reporting of design rationales constituting the process of developing interventions.

Public Engagement in Environmental Impact Studies: A Case Study of Professional Communication in Transportation Planning

Background : Environmental impact studies often enlist professional communicators to develop and implement public engagement plans and processes. However, few detailed reports of these public engagement plans exist in either scholarly venues or government reports. This case reviews one public engagement project in transportation planning as implemented by one professional communications firm. Research questions: 1) What communication and engagement strategies do the consultants employ in their public engagement process? 2) How do professional communicators design engagement for diverse citizen groups? Situating the case: A number of cases have revealed the ways professional and technical communicators integrate participatory or user-centered design strategies in public engagement projects. These cases suggest that professional and technical communicators are uniquely positioned to develop ethical and effective public engagement plans for environmental impact studies. Professional and technical communicators are further prepared for this work because of their knowledge about theories of intercultural communication and rhetorical theories of delivery. Methodology: This case was studied over the course of 1.5 years using qualitative research methods, including observations, interviews, and textual analysis. About the case: This case reviews the work of one particular public engagement firm, VTC Communications, as they planned and implemented public engagement in one environmental impact study. This environmental impact study team was tasked with determining the best way to accommodate the increase in rail traffic the city anticipated with the development of the high-speed rail. The public's input was needed to fulfill environmental impact statement (EIS) requirements and to fully understand the community concerns regarding the increased traffic, noise, vibrations, and family/business displacements. VTC Communications was hired to conduct this portion of the environmental impact study, and their work included the development of a range of deliverables and events. Conclusions: This case provides an overview of the process of developing public engagement plans, the deliverables designed, as well as the key goals that guided the development of public engagement. My case suggests that effective public engagement can address intercultural concerns by developing projects that are adaptable, multimodal, and dialogic.

Rural eHealth Nutrition Education for Limited-Income Families: An Iterative and User-Centered Design Approach

Background Adult women living in rural areas have high rates of obesity. Although rural populations have been deemed hard to reach, Internet-based programming is becoming a viable strategy as rural Internet access increases. However, when people are able to get online, they may not find information designed for them and their needs, especially harder to reach populations. This results in a “content gap” for many users.Objective User-centered design is a methodology that can be used to create appropriate online materials. This research was conducted to apply a user-centered approach to the design and development of a health promotion website for low-income mothers living in rural Maryland.Methods Three iterative rounds of concept testing were conducted to (1) identify the name and content needs of the site and assess concerns about registering on a health-related website; (2) determine the tone and look of the website and confirm content and functionality; and (3) determine usability and acceptability. The first two rounds involved focus group and small group discussions, and the third round involved usability testing with individual women as they used the prototype system.Results The formative research revealed that women with limited incomes were enthusiastic about a website providing nutrition and physical activity information targeted to their incomes and tailored to their personal goals and needs. Other priority content areas identified were budgeting, local resources and information, and content that could be used with their children. Women were able to use the prototype system effectively.Conclusions This research demonstrated that user-centered design strategies can help close the “content gap” for at-risk audiences.

User-Centered Design for Information Professionals

Most information professionals would agree that user-centered design makes an important contribution to high quality information systems. However, there is no general agreement about how to define the term user-centered design, or how best to implement user-centered design strategies in the development of systems and services. This paper describes a wide range of meanings associated with user-centered design in information studies and in other cognate disciplines, and argues for a more coherent and widely accepted definition. It proposes that a general definition of user-centered design drawn from the literature of human-computer interaction (HCI) could serve as a basic framework for system design and support interdisciplinary work. It also describes some useful methods of implementing this framework in the development of user-centered information systems.
