RESUMO

BACKGROUND: Psychological internet-based interventions have shown promise in preventing and treating perinatal depression, but their effectiveness can be hindered by low user engagement. This challenge often arises from a misalignment between technology attributes, user needs, and context. A user-centered, iterative approach involving all stakeholders is recommended. OBJECTIVE: In this paper, we aimed to develop a user-friendly psychological internet-based intervention aimed at addressing the symptoms of perinatal depression through an iterative, user-centered approach. METHODS: The development process followed the Center for eHealth Research and Disease Management Roadmap phases of contextual inquiry, value specification, and design. It involved a comprehensive literature review, 2 surveys, 10 focus groups, 5 usability interviews, and 1 technical pilot. RESULTS: The contextual inquiry revealed a demand for accessible interventions for perinatal mental health, with internet-based solutions seen as viable options. Insights from the literature influenced intervention content and features. Stakeholders' openness to the intervention became evident during this phase, along with the integration of the first set of values. Initially, we assessed the broader perinatal context to identify the optimal period for the intervention. On the basis of the findings and practical considerations, we decided to specifically target postpartum depression symptoms. The value specification phase further defined the central values and translated them into requirements. In the design phase, feedback was obtained on the user experience of an early digital prototype and on the prototype's final version. The resulting intervention, named Mamá, te entiendo ("Mom, I get you"), is a guided web app based on cognitive behavioral therapy principles, integrating elements from attachment and mentalization theories. It aims to reduce depressive symptoms in women during the first months postpartum and consists of 6 core sequential modules, along with 3 additional modules, including 5 case examples illustrating depressive symptoms and therapeutic techniques. The intervention provides homework exercises and offers users the opportunity to receive feedback from an e-coach through the web app. CONCLUSIONS: This study emphasizes the importance of a user-centered and iterative development process for psychological internet-based interventions. This process helps clarify user needs and provides valuable feedback on service design and quality, ultimately having the potential to enhance the utility and, presumably, the effectiveness of the intervention. The Discussion section shares valuable insights from the project, such as the value of the requirement sessions.

RESUMO

Background: Children can learn efficiently with well-designed serious games. The use of applications to promote health has proliferated, but there is a lack of scientific studies on educational games in oral health. Materials and Methods: We developed the Brazilian version of a British and Jordanian oral health education game for children from the perspectives of Brazilian specialists and users. This descriptive study, with a qualitative and quantitative approach, comprised three phases: I-Experts' discussion of the appropriateness of the previous version of the game to Brazil; II-Development of the first Brazilian version of the game; and III-Evaluation of the first version with 15 children from 4 to 8 years of age. Results: In Phase I, the specialists agreed with the development of the Brazilian version of the game, with minor adjustments on: advice on eating; advice on oral hygiene habits, users' age group, game characters, and game purpose. Phase II: a version with a few changes in images and recommendations, written and spoken in Brazilian Portuguese. Phase III: The global average of correct answers in the game's tasks was 75.3%, ranging from 50.0% to 100%. Children reported having fun with the game, and most understood the content and its interface; their parents found the information relevant and enjoyed the gameplay with their children. Conclusions: The Oral Health Education Game offered basic information for preventing dental caries to Brazilian children aged 4-8 years old in an interactive and fun way; it could support professionals in improving oral health education.

RESUMO

BACKGROUND: Since the early 2000s, there has been a growing interest in using exercise video games (exergames) and virtual reality (VR)-based interventions as innovative methods to enhance physical rehabilitation for individuals with multiple disabilities. Over the past decade, researchers and exercise professionals have focused on developing specialized immersive exercise video games for various populations, including those who have experienced a stroke, revealing tangible benefits for upper limb rehabilitation. However, it is necessary to develop highly engaging, personalized games that can facilitate the creation of experiences aligned with the preferences, motivations, and challenges communicated by people who have had an episode of stroke. OBJECTIVE: This study seeks to explore the customization potential of an exergame for individuals who have undergone a stroke, concurrently evaluating its usability as a technological tool in the realm of physical therapy and rehabilitation. METHODS: We introduce a playtest methodology to enhance the design of a VR exergame developed using a user-centered approach for upper limb rehabilitation in stroke survivors. Over 4 playtesting sessions, stroke survivors interacted with initial game versions using VR headsets, providing essential feedback for refining game content and mechanics. Additionally, a pilot study involving 10 stroke survivors collected data through VR-related questionnaires to assess game design aspects such as mechanics, assistance, experience, motion sickness, and immersion. RESULTS: The playtest methodology was beneficial for improving the exergame to align with user needs, consistently incorporating their perspectives and achieving noteworthy results. The pilot study revealed that users had a positive response. In the first scenario, a carpenter presents a game based on the flexion-extension movement of the elbow; the second scenario includes a tejo game (a traditional Colombian throwing game) designed around game mechanics related to the flexion-extension movement of the shoulder; and in the third scenario, a farmer challenges the player to perform a movement combining elbow flexion and extension with internal and external rotation of the shoulder. These findings suggest the potential of the studied exergame as a tool for the upper limb rehabilitation of individuals who have experienced a stroke. CONCLUSIONS: The inclusion of exergames in rehabilitation for stroke-induced hemiparesis has significantly benefited the recovery process by focusing on essential shoulder and elbow movements. These interactive games play a crucial role in helping users regain mobility and restore practical use of affected limbs. They also serve as valuable data sources for researchers, improving the system's responsiveness. This iterative approach enhances game design and markedly boosts user satisfaction, suggesting exergames have promising potential as adjunctive elements in traditional therapeutic approaches.

RESUMO

Background: Noninvasive ventilation (NIV) provides positive pressure through different interfaces. A multifunctional full-face mask prototype was developed to provide NIV from three sources: ICU ventilators, portable ventilators, and high-flow medical gas pipeline systems. This study aimed to evaluate the usability of this prototype mask. Methods: This was a quantitative experimental study, conducted in two phases: the development of a full-face mask prototype NIV interface, and the evaluation of its usability by health professionals (evaluators) using a heuristic approach. The Wolf Mask prototype is a multifunctional full-face mask that makes it possible to deliver positive pressure from three different sources: microprocessor-controlled ICU ventilators, portable ventilators with single-limb circuits, and high-flow medical gas. The evaluation was conducted in three stages: presentation of the prototype to the evaluators; skills testing via simulation in a clinical environment; and a review of skills. Results: The prototype was developed by a multidisciplinary team and patented in Brazil. The evaluators were 10 health professionals specializing in NIV. Seven skills related to handling the prototype were evaluated. Three of the ten evaluators called for (non-urgent) changes to improve recognition of the components of the prototype. Only one evaluator called for (non-urgent) changes to improve recognition of the pieces, assembly, and checking the mask. Conclusions: The newly developed multifunctional full-face mask prototype demonstrated excellent usability for providing noninvasive ventilation from multiple sources. Minor modifications may further improve the design.

RESUMO

As a consequence of technological advances, the number of devices has increased, with the emergence of different smartphones, tablets, and smartwatches present in both personal and professional activities. As a result, mobile applications have been developed, and with them comes the need for techniques and methods that provide support for conducting evaluation and prototyping since the current approaches are limited and cannot support the complexity and the need for understanding the context. The overall goal of the study is to evaluate the applicability of adopting a situated and embodied approach to mobile application usability testing. The aspects of postmodern and phenomenological approaches were taken into consideration. The study was conducted using the technique of digital ethnography, in particular the re-enactment technique, combined with qualitative research techniques to capture the evidence that the situated and embodied approach allows for capturing the perceptions and experience of the participants about the use of the application under evaluation. As motivation, there is the theoretical and methodological evolution and contribution and the proof that the postmodern and situated approach allows us to evaluate the usability of mobile applications in a complete way, considering the context and the user experience. The results show aspects of experience, reflections, perceptions, contingencies, practices, and meanings that go beyond the complexity of interactions and context with the use of the application, reinforcing the effectiveness of the use of the situated prototyping approach.

RESUMO

Children with autism spectrum disorder (ASD) have deficits in social interaction and expressing and understanding emotions. Based on this, robots for children with ASD have been proposed. However, few studies have been conducted about how to design a social robot for children with ASD. Non-experimental studies have been carried out to evaluate social robots; however, the general methodology that should be used to design a social robot is not clear. This study proposes a design path for a social robot for emotional communication for children with ASD following a user-centered design approach. This design path was applied to a case study and evaluated by a group of experts in psychology, human-robot interaction, and human-computer interaction from Chile and Colombia, as well as parents of children with ASD. Our results show that following the proposed design path for a social robot to communicate emotions for children with ASD is favorable.

RESUMO

Wearable devices designed to improve medication adherence can emit audible and vibrating alerts or send text messages to users. However, there is little information on the validation of these technologies. The aim of this scoping review was to investigate the involvement of human volunteers in the development and evaluation of wearable devices. A literature search was conducted using six databases (MEDLINE, Embase, Scopus, CINAHL, PsycInfo, and Web of Science) up to March 2020. A total of 7087 records were identified, and nine studies were included. The wearable technologies most investigated were smartwatches (n = 3), patches (n = 3), wristbands (n = 2), and neckwear (n = 1). The studies involving human volunteers were categorized into idea validation (n = 4); prototype validation (n = 5); and product validation (n = 1). One of them involved human volunteers in idea and prototype validation. A total of 782 participants, ranging from 6 to 252, were included. Only five articles reported prior approval by a research ethics committee. Most studies revealed fragile methodological designs, a lack of a control group, a small number of volunteers, and a short follow-up time. Product validation is essential for regulatory approval and encompasses the assessment of the effectiveness, safety, and performance of a wearable device. Studies with greater methodological rigor and the involvement of human volunteers can contribute to the improvement of the process before making them available on the market.

ABSTRACT Purpose To evaluate the usability and satisfaction of users with the interface of the 'Agente Escuta' application, in addition to identifying problems and possibilities for improvement. Methods Descriptive exploratory translational study, characterized by a usability test with a quantitative and qualitative approach, subdivided into three stages: (I) prior evaluation of usability by 10 judges, including students, primary care professionals, professors and researchers in Information Technology and Speech Therapy; (II) evaluation of the application by the target audience, that is, community health agents from six municipalities in Rio Grande do Norte; (III) evaluation of the satisfaction of the agents who used the application in their work routine. The System Usability Scale and the Net Promoter Score were used, in addition to a qualitative evaluation of the opinions. Results Usability was rated as excellent by judges, regardless of category. In the evaluation by community health agents, usability was considered good and there was no effect of the city of origin. It was found that the perception of the judges and the target audience were different, with a lower score for the participants in the second stage. However, most would give positive publicity to the product. The heuristic with the highest score was ease of memorization and participants in the third stage were interested in continuing to use the tool in practice, even after the end of the study. Conclusion The Agente Escuta prototype showed good usability and satisfaction and aspects that could be improved in future solutions were identified.

Materials and methods: In the first stage, nine caregivers/former caregivers assessed the interface of the platform that hosts iSupport-BR. In the second stage, 10 caregivers assessed acceptability of the platform and answered the System Usability Scale (SUS), which varies from 0 to 100 points. A descriptive analysis of the quantitative data was performed, as well as a thematic analysis on the open questions. All the ethical aspects were respected. Results: The results of the first stage indicated a user-friendly interface of the system and relevant content of the program, with 55.6 and 77.8% of the participants assigning the maximum grade to these questions, respectively. Of the five possible points, the system's mean score was 3.7. In Stage 2, 80% of the caregivers rated the program as very useful and 100% would recommend it to other caregivers. Perception of the program's usability by the SUS scale was excellent (M = 86.5 ± 11.5). Conclusion: This research allowed elaborating the final version of iSupport-BR, considering usability and acceptability of the platform and the program for computers/notebooks, being a pioneer in evaluating it for use in smartphones. Future research studies will have to assess the effects of iSupport-BR on the caregivers' mental health.

RESUMO

A informatização da medicina busca potencializar o sistema de saúde, mas diversas dificuldades são encontradas na usabilidade dos sistemas pelos profissionais. No Brasil, sabe-se muito pouco sobre a percepção dos médicos sobre o uso de prontuários eletrônicos. O objetivo desta pesquisa foi identificaro nível de satisfação dos médicos de família com o uso de prontuários eletrônicos. Trata-se de pesquisa observacional transversal, com aplicação de questionário para a avaliação do grau de satisfação dos usuários de prontuários eletrônicos. Para a análise, foi utilizada a metodologia de mineração de dados com ferramentas específicas. O alto nível de satisfação esteve relacionado à capacidade de o prontuário prevenir erros, prover prescrição rápida e fácil, ajudar a atender mais pacientes, facilitar a discussão de casos e realizar tarefas. Jáa insatisfação esteve relacionada a suporte técnico ruim, falta de ferramentas de suporte à decisão clínica, ser empecilho à relação médico paciente e alertas ruins. Apesar do nível de satisfação geral ser baixo, os médicos demonstraram gostar de usar o prontuário eletrônico. Este estudo é uma oportunidade para reflexão sobre as demandas mais urgentes no aprimoramento desses sistemas e para planejamento de ações futuras.

The informatization of medicine aims to improve the health system. Professionals encounter several difficulties with the usability of systems. In Brazil, very little is known about physicians' perceptions of the use of electronic medical records. The objective of this research is to identify the level of satisfaction of family doctors with the use of electronic medical records. This is a cross-sectional observational study, with the application of a questionnaire to assess the degree of the user's satisfaction with electronic medical records. For analysis, the data mining methodology with specific tools was used. A high level of satisfaction was related to several factors: the ability of the medical record to prevent errors, quick and easy prescriptions, support in seeing more patients, facilitating case discussions, and task performance. On the other hand, dissatisfaction was related to poor technical support, lack of clinical decision support tools, obstructing the doctor-patient relationship, and deficient alerts. Despite the low level of overall satisfaction, physicians demonstrated that they enjoyed using the electronic medical record. This study is an opportunity to reflect on the most urgent demands for improving these systems and plan future actions.

RESUMO

Background: Patients with chronic respiratory diseases require oxygen supply in a considerable amount to reduce their symptoms and increase their survival. The development of abilities for the self-management of chronic diseases has been shown to be essential to decrease exacerbation of symptoms. Therefore, the design and development of health mobile applications (apps) that aid in educating and training for disease self-management are cost-effective strategies. Objective: The purpose of this research was to describe the main characteristics that, according to final users, should be included in a mobile application for monitoring patients prescribed home oxygen therapy. Methods: A participative-qualitative design was used, involving direct participation of patients, caregivers, and healthcare professionals. Focus groups were conducted to identify the needs and perspectives related to the app. A card sorting method was used to determine the contents and basic architecture of the app. Results: By means of the focus groups, we could identify nine basic functions of the app for the clinical monitoring of patients under home oxygen therapy. For both profiles, the app structure was determined by identifying the most frequent contents among participants. Conclusions: The implementation of a user-centered design allowed for the detection of the functions, contents, and basic architecture of the app by identifying healthcare professionals and patients' needs and preferences regarding the self-management and monitoring of home oxygen prescriptions. Trial Registration: The study is registered in ClinicalTrials.gov: NCT04820790.

RESUMO

BACKGROUND: In this work, we share the enhancements made in our system to take part in the CYBATHLON 2020 Global Edition Functional Electrical Stimulation (FES) Bike Race. Among the main improvements, firstly an overhaul, an overhaul of the system and user interface developed with User-centered design principles with remote access to enable telerehabilitation. Secondly, the implementation and experimental comparison between the traditional single electrode stimulation (SES) and spatially distributed sequential stimulation (SDSS) applied for FES Cycling. METHODS: We report on the main aspects of the developed system. To evaluate the user perception of the system, we applied a System Usability Scale (SUS) questionnaire. In comparing SDSS and SES, we collected data from one subject in four sessions, each simulating one race in the CYBATHLON format. RESULTS: User perception measured with SUS indicates a positive outcome in the developed system. The SDSS trials were superior in absolute and average values to SES regarding total distance covered and velocity. We successfully competed in the CYBATHLON 2020 Global Edition, finishing in 6th position in the FES Bike Race category. CONCLUSIONS: The CYBATHLON format induced us to put the end-user in the center of our system design principle, which was well perceived. However, further improvements are required if the intention is to progress to a commercial product. FES Cycling performance in SDSS trials was superior when compared to SES trials, indicating that this technique may enable faster and possibly longer FES cycling sessions for individuals with paraplegia. More extensive studies are required to assess these aspects.

RESUMO

BACKGROUND: Older people often do not meet the recommended levels of exercise required to reduce functional decline. Social interaction is mentioned by this cohort as a reason for joining group-based exercises, which does not occur when exercising alone. This perspective shows that exergames can be used as motivational resources. However, most available exergames are generic, obtained from commercial sources, and usually not specifically designed or adapted for older people. OBJECTIVE: In this study, we aim to co-design and develop a new exergame alongside older participants to (1) tailor the game mechanics and optimize participants' adherence to and enjoyment of exercise; (2) test the participants' functional capacity, motivation, and adherence to the exergaming program; and (3) compare these scores between those who played alone and those who played with peers. METHODS: We conducted a co-design process to develop a new exergame adapted to older people. For user testing, 23 participants were divided into 2 groups to play individually (alone group) or to compete in pairs (with peers group). They played the game twice a week, resulting in 21 exergaming sessions. We assessed the participants' General Physical Fitness Index (GPFI) before and after the user testing. We also administered questionnaires about the gaming experience and exercise adherence with its motivators and barriers. RESULTS: We introduced a new bowling exergame for Xbox with a Kinect motion sensor that can be played in single or multiplayer mode. For the GPFI measurements, the sample was homogeneous in the pretest (with peers group: mean 40.5 [SD 9.6], alone group: mean 33.9 [SD 7.8]; P=.11). After the exergame testing sessions, both groups had significant gains (with peers group: mean 57.5 [SD 8.7], P=.005; alone group: mean 44.7 [SD 10.6]; P=.02). Comparing the posttest between groups, it was found that the group in which participants played with peers had better outcomes than the group in which participants played alone (P=.02). Regarding the gaming experience and exercise adherence, both groups recognized the benefits and expressed enthusiasm toward the exergame. CONCLUSIONS: The findings suggest that the developed exergame helps in improving the functional capacity and adherence to physical exercise among older people, with even better results for those who played with peers. In addition to leading to more appropriate products, a co-design approach may positively influence the motivation and adherence of participants.

RESUMO

ABSTRACT OBJECTIVE To develop and evaluate the usability of the admission monitoring system in an emergency room. METHODS This applied research intends to develop a software product and evaluate its usability. The development followed four stages: systematic review, structuring of the system framework, construction of system forms, and evaluation of the information generated. In the evaluation, the experts simulated the use of the system by inserting data from a fictitious medical record. We measured usability using the System Usability Scale (SUS). Scores and scores were calculated individually and globally. We propose these evaluation standards: worst case scenario, poor, average, good, excellent, and best-case scenario. RESULTS The Sistema de Informação e Monitoramento das Internações em Pronto-Socorro (SIMIPS - Information and Monitoring System for Emergency Room Admissions) monitors the epidemiological profile of admissions to the emergency room, time management, clinical deterioration, incidence of adverse events, and human resource management. The usability of SIMIPS, evaluated by 17 experts, reached the SUS Score 86.5 (best case scenario), and some suggestions for modifications were accepted. CONCLUSIONS We consider SIMIPS an easy-to-use tool, with real importance in the management of emergencies in view of overcrowding and congestion problems faced in Brazil.

RESUMO OBJETIVO Desenvolver e avaliar a usabilidade de um sistema de monitoramento das internações em pronto-socorro. MÉTODOS Trata-se de uma pesquisa aplicada, com desenvolvimento de um produto de software e avaliação de sua usabilidade por enfermeiros especialistas. O desenvolvimento seguiu quatro etapas: revisão sistemática, estruturação do arcabouço do sistema, construção dos formulários do sistema e avaliação das informações geradas. Na avaliação, os especialistas simularam a utilização do sistema com a inserção de dados de um prontuário fictício, e a usabilidade foi medida pelo System Usability Scale (SUS). A pontuação e os escores foram calculados de forma individual e global. O sistema foi avaliado nos padrões: pior imaginável, pobre, mediano, bom, excelente e melhor imaginável. RESULTADOS O Sistema de Informação e Monitoramento das Internações em Pronto-Socorro (SIMIPS) realiza o monitoramento do perfil epidemiológico das internações no pronto-socorro, gestão de tempo, deterioração clínica, incidência de eventos adversos e gestão de recursos humanos. A usabilidade do SIMIPS, avaliada por 17 especialistas, atingiu o Score SUS 86,5 (melhor imaginável), e algumas sugestões de modificações foram acatadas. CONCLUSÕES O SIMIPS foi avaliado como uma ferramenta de fácil utilização, com real importância na gestão das urgências frente aos problemas de superlotação e congestão, enfrentados no Brasil.

RESUMO

BACKGROUND: Marketing clothes online can be challenging for those who buy and sell them. They are products that people still feel the need to have direct contact with. Some of their attributes are not easily communicated digitally, such as the fit and the feel of the fabric. Besides, the lack of standardization of sizes practiced by the Brazilian clothing industry raises several doubts to the user. OBJECTIVE: The objective of this paper is to present the results of an investigation concerning the user experience (UX) resulting from the interaction with female e-commerce websites. METHODS: The methods were organized into two stages: exploratory and descriptive. The former consisted of an exploratory interview (19 interviewees), an online questionnaire (205 respondents), and semi-structured interviews with 5 fashion specialists. In the latter, 60 users were divided into two groups of 30 participants to undertake a usability test on an e-commerce website (dafiti.com.br) to evaluate the UX when buying clothes. Group A used a desktop/laptop and Group B used a smartphone. The users were then debriefed and answered the AttrakDiff2™ questionnaire. RESULTS: Users lacked technical knowledge on clothing attributes and were extremely wary about the size and fit information provided (60% in Group A and 83% in Group B were not sure about fit and size information). Surprisingly, the AttrakDiff2™ showed no significant difference between the mobile or the desktop/laptop UX (Group A: M = 4.0 SD = 0.1; Group B: M = 4.1 SD = 0.2). CONCLUSIONS: The most significant problem faced by the users concerned the fit and sizing information, as these attributes are usually poorly communicated digitally. In addition to being a usability problem, by inducing users to errors, its greatest impact was on the UX.
