... The content of those first works highlighted the importance of obtaining benefits in the software industry, through usability engineering (Nielsen, 1990;Nielsen, 1993). Implicitly, use was made of pre-existing techniques and methodologies used in some of the disciplines that made up social communication in the 1980s and 1990s on the American continent, such as sociology, statistics, psychology, communication theory, cultural systems, linguistics, semiotics, logic programming, and so on. ...
... In addition, it overcomes the current interpretation error, which is made of the "subjectively pleasant" notion, in the use of new technologies. This concept comes from one of the five basic principles of usability engi- neering (Nielsen, 1993). This interpretation error entails the erroneous use of endless new terms, such as empathy, emotion, playability, serious games, etc. ...
In this chapter, the notion of "context" is analyzed and included as a new category when designing interactive systems that are efficiently communicative with the latest generation of technology, that is to say, the distance and interrelation of the designer with the real world, particularly from the sociological and computer point of view, with a special emphasis on the development of content for education in emergency situations. In it, the notion of communicability is updated, and the main successes and failures are presented, given the use of new concepts belonging to the field of new technologies, the communi-cability and design for the quantic-nanotechnological-self-sufficient era. The main errors in the one-to-one relationship between meaning and signifier of these new concepts in the field of human-computer interaction and all its derivations, from the 21st century, are also disclosed. Finally, the social factors of humanistic computing that harm the heuristic and neutral evaluation of the new millenn

Ensuring usability is crucial for the success of mobile apps. Usability issues can compromise user experience and negatively impact the perceived app quality. This paper presents UX-LLM, a novel tool powered by a Large Vision-Language Model that predicts usability issues in iOS apps. To evaluate the performance of UX-LLM we predicted usability issues in two open-source apps of a medium complexity and asked usability experts to assess the predictions. We also performed traditional usability testing and expert review for both apps and compared the results to those of UX-LLM. UX-LLM demonstrated precision ranging from 0.61 and 0.66 and recall between 0.35 and 0.38, indicating its ability to identify valid usability issues, yet failing to capture the majority of issues. Finally, we conducted a focus group with an app development team of a capstone project developing a transit app for visually impaired persons. The focus group expressed positive perceptions of UX-LLM as it identified unknown usability issues in their app. However, they also raised concerns about its integration into the development workflow, suggesting potential improvements. Our results show that UX-LLM cannot fully replace traditional usability evaluation methods but serves as a valuable supplement particularly for small teams with limited resources, to identify issues in less common user paths, due to its ability to inspect the source code.

With the aging of the population, technology has emerged as a promising avenue to tackle the challenges faced by older adults. Artificially Intelligent (AI) voice assistants (VAs) have been widely recognized as a potential solution to meet the needs of the elderly population, as demonstrated in various related projects. The hands-free interface and increasingly personalized capabilities of technology can offer a wide range of benefits for older adults. To ensure the long-term and stable value of AI VAs in older adults, it is necessary to evaluate their continued-use intention. Based on the S-O-R framework, technology acceptance model and attachment theory, we construct a model to explore the relationship between different personalized features of AI VAs, emotional attachment, perceived ease of use, perceived usefulness, and continued-use intention among older adults, and to analyse whether technology anxiety plays a moderating role between emotional attachment and continued-use intention. The results confirm that the personalized response and recommendation of AI VAs have a significant impact on perceived ease of use, while personalized voice interfaces do not. In addition, emotional attachment not only improves older users’ perceptions of the ease of use and usefulness, but also positively influences continued-use intention together with both of them. The presence of technology anxiety, on the other hand, did not have an impact on the relationship between emotional attachment and continued-use intention.

Introduction
Usability plays a critical role in the design of mHealth applications. A well-designed app enhances user experience and contributes to better healthcare outcomes. However, it remains unclear which usability criteria are often neglected, leading to issues in the actual use of these applications. This study aimed to identify and categorize the usability issues of mHealth applications, mapping them to Nielsen’s usability principles to determine the most critical criteria.
Methods
The PRISMA guidelines were followed to report the results. Different databases (PubMed, Scopus, WoS) were searched for systematic reviews and/or meta-analyses about usability evaluation in mHealth applications. Two reviewers independently applied predefined selection criteria, extracted data, and assessed methodological quality using the AMSTAR tool.
Results
Eight studies met the inclusion criteria. The most common method used in studies to evaluate the usability of mHealth applications was the questionnaire. Researchers identified 79 usability issues from the studies. Eleven of the issues were related to the Aesthetic and minimalist design category. The category of Flexibility and efficiency of use was next (n = 10).
Conclusion
This study identified the usability issues that individuals face when using mHealth applications. By mapping these issues to evaluation criteria, developers can systematically address and prevent them. Attention to these issues will lead to better design and more effective use of mHealth applications.

This study explores the impact of social media engagement on online consumer behavior as well as the factors influencing online shopping adoption among Yemeni consumers. The research includes two main studies: an exploratory phase for scale development and a quantitative analysis phase. The study employs robust statistical techniques, including EFA, CFA, and SEM to validate measurement scales and analyze relationships.
The study, conducted with a sample size of 395 social media users in Yemen during May- October 2022, adopted three different scales for the Arabic language and the results showed that the social media engagement scale is a unidimensional concept, while the online consumer behavior scale is a multidimensional concept, consisting of three distinct factors: awareness, social cognition, and online business perception. The extended unified theory of acceptance and use of technology scale was found to be a valid measure of the three key factors that predict adoption: price value, usability, and adoption intention.
Key findings include demographic variables like gender, age, and education have limited impact on online shopping behavior. Social media engagement sets the foundation by influencing social cognition, which, in turn, enhances awareness of online shopping. This awareness then affects online business perception and perceived usability, leading to an impact on the perceived price value of online shopping. Finally, the perceived price value plays a crucial role in shaping the intention to adopt online shopping.
The study highlights the trail of online shopping as a moderating factor as it weakens the direct impact of social media engagement, social cognition, awareness, and usability while strengthening the influence of online business perception. The findings underscore the importance of considering indirect effects and mediating pathways in understanding the relationships among variables in the model.
This holistic perspective is essential for a comprehensive understanding of the dynamics and interplay within the model, providing valuable insights for researchers and practitioners in the context of online shopping behavior.

Background
Increasing adoption of sensor-based digital health technologies (sDHTs) in recent years has cast light on the many challenges in implementing these tools into clinical trials and patient care at scale across diverse patient populations; however, the methodological approaches taken toward sDHT usability evaluation have varied markedly.
Objective
This review aims to explore the current landscape of studies reporting data related to sDHT human factors, human-centered design, and usability, to inform our concurrent work on developing an evaluation framework for sDHT usability.
Methods
We conducted a scoping review of studies published between 2013 and 2023 and indexed in PubMed, in which data related to sDHT human factors, human-centered design, and usability were reported. Following a systematic screening process, we extracted the study design, participant sample, the sDHT or sDHTs used, the methods of data capture, and the types of usability-related data captured.
Results
Our literature search returned 442 papers, of which 85 papers were found to be eligible and 83 papers were available for data extraction and not under embargo. In total, 164 sDHTs were evaluated; 141 (86%) sDHTs were wearable tools while the remaining 23 (14%) sDHTs were ambient tools. The majority of studies (55/83, 66%) reported summative evaluations of final-design sDHTs. Almost all studies (82/83, 99%) captured data from targeted end users, but only 18 (22%) out of 83 studies captured data from additional users such as care partners or clinicians. User satisfaction and ease of use were evaluated for 83% (136/164) and 91% (150/164) of sDHTs, respectively; however, learnability, efficiency, and memorability were reported for only 11 (7%), 4 (2%), and 2 (1%) out of 164 sDHTs, respectively. A total of 14 (9%) out of 164 sDHTs were evaluated according to the extent to which users were able to understand the clinical data or other information presented to them (understandability) or the actions or tasks they should complete in response (actionability). Notable gaps in reporting included the absence of a sample size rationale (reported for 21/83, 25% of all studies and 17/55, 31% of summative studies) and incomplete sociodemographic descriptive data (complete age, sex/gender, and race/ethnicity reported for 14/83, 17% of studies).
Conclusions
Based on our findings, we suggest four actionable recommendations for future studies that will help to advance the implementation of sDHTs: (1) consider an in-depth assessment of technology usability beyond user satisfaction and ease of use, (2) expand recruitment to include important user groups such as clinicians and care partners, (3) report the rationale for key study design considerations including the sample size, and (4) provide rich descriptive statistics regarding the study sample to allow a complete understanding of generalizability to other patient populations and contexts of use.
... For this research, a user-centered approach will be used in order to obtain the necessary requirements for the development of the solution. As [14] indicates, this approach focuses on the development of software according to the needs and desires of the end users, who in this case are people with visual disabilities. In this sense, we follow four stages: ...
Requirements analysis is crucial in software system development. With the growth of Artificial Intelligence (AI)-based solutions, this analysis has gained greater importance to create more robust and accessibility-focused solutions. This study defines the software requirements for designing a virtual assistant that utilizes Natural Language Processing (NLP) to facilitate navigation through voice commands for visually impaired people on the EMINUS educational platform, belonging to the Universidad Veracruzana. The necessary requirements are detailed using Google Cloud Text-to-Speech API, neural networks with Bayesian classification algorithms, Rest API services through Node.js, JavaScript, and HTML5 for creating a plugin in Google Chrome.
... The concurrent think aloud method is a common procedure in the field of digital healthcare for testing technologies with regard to usability, content and accuracy of fit. 29 Users are asked to verbalise their thoughts while getting acquainted with the application for the first time. 28 In addition, the participants receive a catalogue of tasks that are based on typical activities during initial use (eg, using the menu, moving through the various parts of the DiGA, open and view content). ...
Introduction
The prevalence of mental health problems is increasing worldwide, particularly in the vulnerable group of older people. The limited availability of therapists, long wait periods and increasing shortage of healthcare resources limit adequate care. As a result, digital applications are becoming more commonplace as an alternative to human therapists. However, these tend to be used by younger people with higher education, digital health literacy and experience. In Germany, applications that are approved by the health authorities, so-called digital health applications (DiGAs), can be prescribed by physicians and psychotherapists. It remains unclear to the extent older people are experienced with, are willing and can use a DiGA. Therefore, this research aims to identify specific challenges of older people’s accessibility, user experience and engagement with DiGA for depressive disorders. The DiGA4Aged project consists of: (1) a pilot study on usability, (2) a screening study on potential participants for a randomised controlled trial (RCT) evaluating the digital experience of the target population and (3) an RCT to test the effectiveness of a digital nurse as individualised user support in the intervention group. This paper focuses on the pilot study and the screening study.
Methods and analysis
The instrumental components in preparing for the RCT are a mixed-method pilot and observational quantitative screening study, which are described in this manuscript. The pilot study includes questionnaires (covering sociodemographic data, user experience, health literacy, electronic health literacy, media affinity, severity of depression and perceived usability of DiGA), a concurrent think aloud method and a semistructured interview to evaluate two applications with regard to their usability for, acceptance by and needs of older people. The observational screening study collects data of older patients consecutively admitted to an acute care geriatric hospital ward using various questionnaires to identify which clinical and medical factors are associated with the access to, experience with and (non-)use of digital media. Data from the comprehensive geriatric assessment is collected as well as data on their digital media experience and digital health literacy.
Ethics and dissemination
The overall project DiGA4Aged received ethical approval on 17 November 2023 from the ethics committee of the Medical Faculty of Ruhr-University Bochum (registration number 23-7901). Results will be disseminated within the scientific community via publication in peer-reviewed journals as well as presentation at national conferences. The findings from the pilot study and the observational screening study will determine the selection of the DiGA and the recruitment strategy for the subsequent RCT.
Trial registration numbers
The pilot study has been prospectively registered in the German Clinical Trials Register (DRKS00033640, registered on 18 March 2024, available from https://drks.de/search/de/trial/DRKS00033640 ). Likewise, the observational screening study has been prospectively registered in the German Clinical Trials Register (DRKS00032931, registered on 29 November 2023, available from https://drks.de/search/de/trial/DRKS00032931 ).
... In terms of usability, MGG isolates the grasp candidate sampler 18 of 20 and simulation-based grasp validator. This makes the whole validation pipeline sub-optimal from the point of view of usability [32], as the user must collect, modify and export the data from the sampler in the docker to the validator, outside of the docker. Regarding our system, the communication via ROS2 services has proven to be useful in order to communicate the two processes, even if our sampler is embedded in a docker. ...
Current industrial robotic manipulators have made evident their lack of flexibility. The systems must know beforehand the piece and it’s position. To address this issue, contemporary approaches typically employ learning-based techniques, which rely on extensive amounts of data. To obtain vast data, an often sought tool is an extensive grasp dataset. This work introduces our Physics-Based Self-Supervised Grasp Pose Detection (PBSS-GPD) pipeline for model-based grasping point detection, useful to generate grasp pose datasets. Given a gripper-object pair, it samples grasping pose candidates using a modified version of GPD (implementing inner-grasps, CAD support...) and quantifies their quality using the MuJoCo physics engine and a grasp quality metric that takes into account the pose of the object over time. The system is optimised to run on CPU in headless-parallelised mode, with the option of running in a graphical interface or headless and storing videos of the process. The system has been validated obtaining grasping poses for a subset of Egad! objects using the Franka Panda two-finger gripper, compared with state of the art grasp generation pipelines and tested in a real scenario. While our system achieves similar accuracy compared to a contemporary approach, 84% on the real world validation, it has proven to be effective at generating grasps with good centering 18 times faster than the compared system.
... 3) Frustrated: The response time is greater than the frustration threshold F. Users are considered frustrated with the performance of the application. In this work, we adopted 1 second as the tolerance threshold T , and 10 seconds as the frustration threshold F, aligning with policies proposed by Nielsen in [53]. After computing the number of Satisfied, Tolerated, and Frustrated requests during the execution of the performance test, the Apdex metric is computed as: ...
The REST (REpresentational State Transfer) paradigm has become essential for designing distributed applications that leverage the HTTP protocol, enabling efficient data exchange and the development of scalable architectures such as microservices. However, selecting an appropriate framework among the myriad available options, especially given the diversity of emerging execution environments, presents a significant challenge. Often, this decision neglects crucial factors such as performance and energy efficiency, favoring instead developer familiarity and popularity within the industry. To address this, we conducted a comprehensive benchmark study using a prototype REST API application provided by an industry partner, which was implemented multiple times using different REST API frameworks. We evaluated five different REST API frameworks across three popular programming languages, incorporating both traditional and emerging execution environments, resulting in twelve distinct configurations. Our results reveal significant differences in performance and computational resource consumption across different frameworks and execution environments, highlighting the necessity of making informed technology choices based on thorough analysis rather than convenience or familiarity. In addition to our findings, we offer other contributions to the field: an automated pipeline that benchmarks different configurations with various frameworks and execution environments, and a reference benchmark REST API that can be used in other studies. This research provides valuable insights and tools for developers and organizations aiming to select high-performance, resource-efficient technologies that promote environmental sustainability and reduce operational costs.
... The usability testing is a fundamental component of UI/UX design, involving the observation of users as they interact with a product to identify areas for design improvement (Nielsen, 1993). Traditional methods like eye-tracking provide valuable insights into user attention by recording eye movements and generating heatmaps that reveal patterns of focus (Duchowski, 2007). ...
The paper presents a comparative pilot analysis of an AI-based visual attention prediction system with the traditional eye-tracking method in the context of UI/UX design. The study assesses the accuracy and reliability of AI-generated attention heatmaps compared to empirical eye-tracking data. The results indicate that AI systems show a strong ability to approximate human attention, achieving ROC-AUC values between 0.75 and 0.84. The study highlights AI's potential in early-stage design iterations, offering a suitable alternative to time-consuming eye-tracking testing sessions, but recommends combining AI tools with traditional methods for critical design decisions.
... The UX/UI experience was positively received, with minimal requests for interface modifications. This aligns with Nielsen and Molich's usability standards [36], particularly in terms of learnability, efficiency and memorability. Patients felt more involved in therapy, and clinicians valued the tool's guideline adherence. ...
Background
Schizophrenia treatment with antipsychotics often results in side effects that impact adherence and quality of life. Managing these effects remains challenging, as it requires balancing efficacy and tolerability. The Schizophrenia Technological Evaluation of Patient Side Effects (STEP‐SE) app aims to aid side effects monitoring and management through shared decision‐making (SDM).
Aim
This study aimed to evaluate the usability of the STEP‐SE app for patients and clinicians in managing antipsychotic side effects.
Methods
Sixteen stable outpatients and 14 psychiatrists participated in semi‐structured interviews after using the STEP‐SE app. Questions explored ease of use, information clarity, user needs fulfilment, patient–clinician collaboration, treatment adherence improvement, patient empowerment and clinical utility. Data were analysed thematically.
Results
Overall satisfaction with STEP‐SE was high. Both groups found that the tool improved patient involvement, provided reliable information to enhance therapeutic alliance, posed low risks of misunderstanding and had an intuitive interface. Patients felt more motivated and empowered. Clinicians appreciated guideline consistency. Preferences differed regarding data visualization formats.
Discussion
STEP‐SE shows potential for aiding SDM on antipsychotic side effects. Patients gained motivation, and clinicians felt reassured. Refinements around mobile access, graphics and features could augment utility. Generalizability is limited given the stable patient sample.
Conclusion
Preliminary findings suggest that STEP‐SE effectively engages patients, empowers them and supports clinicians in collaborative side effect management. Further testing with diverse user groups is warranted.

The participants’ contributions were key in optimizing STEP‐SE's features and ensuring its relevance and reliability. We thank all who shared their time and perspectives, significantly shaping the tool's user‐centred design.
... A cornerstone of achieving the concept of universal access in the information society is, and remains, good usability. Usability ensures that technologies are intuitive, accessible, and effective for all users, including those with varying abilities and from diverse backgrounds [4]. However, usability is often still neglected, particularly in our AI-centered world, where products tend rather to focus on innovative features [5]. ...
This study explores the usability of human-robot collaboration in the previously under-researched field of forestry and agroforestry. The robotic platforms used were Boston Dynamics Spot and the Agile X Bunker, the latter equipped with a movable arm. The research was conducted in an experimental robotic test park, simulating real-world scenarios relevant to forestry and agriculture. The focus of this study is on the use of these robots as collaborative robots (cobots). Usability, as a central characteristic in human-computer interaction, was evaluated using the well-established System Usability Scale (SUS). The results demonstrate the potential of these robotic systems to enhance productivity and safety, while also underscoring the importance of user-centered design in the development of collaborative tools. A key finding of this work is that successful integration of AI-driven technologies in sectors such as forestry and agriculture requires a focus on human-centered AI which includes good usability, and accessibility, emphasizing the importance of the concept of universal access.
The purpose of this research is to develop a mobile magazine application (M-IKLIM) that provides content on climate change for middle school students within the scope of the TÜBİTAK (The Scientific and Technological Research Council of Turkey) 2209/A project, and to evaluate the usability of this application. The research was conducted using the Design-Based Research (DBR) method. The study group consists of middle school students. The Mobile Application Satisfaction Questionnaire (MASQ), developed by Namlı (2010), was used as the data collection tool. The obtained data were analyzed using descriptive statistics and correlation analyses. In the descriptive analyses, the mean and standard deviation values of each survey question were calculated. In the correlation analyses, the relationships among the survey data were examined. According to the research results, the M-IKLIM application was generally evaluated positively by the students. Students indicated that the application is user-friendly and suitable for its purpose. The survey results show that the application is generally understandable and not complex. Correlation analyses revealed that user-friendly interfaces and the safety of the application increase student satisfaction. However, it was determined that improvements need to be made in some areas. In future studies, it is recommended to analyze user feedback in more detail and continuously improve the application based on this feedback.
Project Management (PM) is vital in software development and the availability of educational tools enhances the learning experience of best practices. This study focuses on developing a web-tool for PM education and employed a service-based software approach to develop a web-tool. We conducted a survey using the LimeSurvey platform to identify PMBOK® aspects to define technical requirements, gather user input for the tool’s new version, and formulate research questions to guide implementation. Survey results from 16 respondents revealed knowledge areas with insufficient PMBOK® coverage and areas needing non-functional improvements. The questionnaire design and administration adhered to best practices, offering valuable insights for tool development. This study emphasizes the significance of PM education and the need for effective tools. The developed web-tool aids students and professors in adhering to best practices and enhancing PM skills. Future research can focus on further enhancing the tool and evaluating its effectiveness in educational settings.
Zusammenfassung
Um die erfolgreiche Einführung eines Informationssystems zu gewährleisten, sollten Erfolgsfaktoren in Organisationen berücksichtigt werden. Dies gilt auch für automatisierte Führungssysteme, die als Informationssysteme im Personalbereich betrachtet werden können. Bei der automatisierten Führung übernehmen intelligente Agenten Führungsaufgaben, die bisher von Menschen ausgeführt wurden. Dies können zum Beispiel Führungsaufgaben wie die Aufgabenverteilung oder das Leistungsfeedback an Mitarbeiter sein. Der Einsatz von automatisierter Führung ist in Unternehmen der Gig-Economy wie MTurk weit verbreitet. In traditionellen Organisationen ist der Einsatz bisher weniger verbreitet. Durch die zunehmende Verlagerung der Arbeitsweise hin zum selbstständigen Arbeiten mit digitalen Medien im Homeoffice wird der Einsatz von automatisierten Führungssystemen in konventionellen Unternehmen prinzipiell möglich. Um zukünftig die erfolgreiche Implementierung dieser Technologie in konventionellen Unternehmen zu gewährleisten, untersucht dieser Beitrag die Erfolgsfaktoren der Implementierung der automatisierten Führung. Dazu wurden qualitative, halbstandardisierte Interviews mit 24 deutschen Führungskräften durchgeführt. Die Ergebnisse der Studie zeigen, dass die Akzeptanz der Nutzer eine zentrale Rolle spielt. Durch die praktische Anwendung der gewonnenen Erkenntnisse können Unternehmen ihre Transformation zur Automatisierung durch Führungssysteme erfolgreich gestalten.

Context
Prioritizing usability in software development is vital to ensure a positive user experience and efficient performance. Failing to do so can result in negative consequences such as increased costs, damage to reputation, and loss of trust. Usability should be considered throughout the entire software development life cycle (SDLC), not just as an afterthought. Accordingly, adopting and integrating usability practices is crucial but can be complex. Thus, organizations must assess their readiness to start and improve usability initiatives. In this context, software organizations can benefit from using a usability readiness model to enhance integration and assist practitioners in systematically and structurally applying usability practices.
Objective
We propose a readiness model for usable software development (RMUSD). This model allows organizations to assess their readiness to create usable software, leading to improved user experience and better usability methods throughout the SDLC.
Method
To develop the RMUSD, we conducted a systematic mapping study that gathered 238 relevant studies in the usability engineering domain. From these studies, we synthesized 50 best usability practices that form the foundation of the RMUSD. We also drew inspiration from existing software engineering readiness and usability maturity models.
Results
The RMUSD is built at five levels, each with various aspects to consider, such as related usability practices, implications, organizational characteristics, and success factors for moving up to the next level. The model was evaluated through two real‐world case studies and eight experts.
Conclusion
The evaluation results reveal that the suggested RMUSD is practical in determining the organization's readiness to develop usable software.
SCHOOLS ARE MADE SAFE TOGETHER!
Normative acts and documents oblige schools to ensure they are safe spaces for learning and working. Media headlines related to school safety frequently highlight bullying, violence, school threats and accidents. Studies show schools need support to develop their safety culture. The aim and task of the Success in School Safety -project 2022–2024 has been to respond to this need by supporting schools in developing their safety and safety culture in a research-based manner.
Twenty schools from different parts of Finland took part: 15 pilot schools and five control schools, involving 964 members of staff and 8299 pupils. During the year-long development program, pilot schools established safety teams, prepared a school safety development plan and established an annual planning cycle for school safety. Schools shared safety notices in staff meetings and took part in meetings for school principals and safety team members. Schools were provided with a web application and a draft of Guidelines for Equitable Sanctions. In addition, school staff received further training and engaged their pupils in safety work.
The project research approached factors that advance school safety culture and changes in schools’ safety culture during the program from multiple perspectives: assessing schools’ self-initiated contingency planning and preparedness, identifying levels of safety culture through focus group interviews, schools’ self-assessment of safety expertise, safety incidents in schools, usability study of HES and developing criteria and methods for assessing the safety culture of schools.
Schools’ safety culture improved already within the first year of development. Schools nationally must carry out systematically led, long-term safety work that engages the whole school community, pupils included, and is founded on up-to-date information of the school’s safety snapshot. The project produced practical approaches and tools for schools: a model of safety culture, a school safety development plan, models for schools’ self-assessment of safety culture, for collecting and processing safety incident notices, for assessing hazards and risks, and a description of the tasks of school safety teams.
Led by the Department of Teacher Education (Rauma campus) of the University of Turku and funded by the Finnish Ministry of Education and Culture, the project was a part of PM Sanna Marin’s operational program to prevent bullying, harassment and violence in early childhood education, schools and educational institutions: to advance the safety culture of comprehensive education learning communities.

User security and data protection are prioritized through compliance with GDPR and other relevant regulations. Key findings from the feasibility study indicate a growing demand for user-centric, feature-rich platforms in the accommodation sector. This platform is technically and financially feasible and has the potential to enhance user satisfaction by offering a more flexible, secure, and transparent marketplace. The platform aims to become a trusted solution for both travellers and property owners while ensuring adaptability for future growth and market trends.
Today, it is almost impossible to avoid interaction with IT-related tools. Therefore, when designing systems, it is important to consider people’s cognitive abilities and limitations to avoid production errors and excessive burden on people. In cognitive ergonomics, the interaction between humans and technology is studied and designed especially from the viewpoint of human cognitive processes. Cognitive ergonomics aims to shorten task times, reduce mistakes made by people, shorten learning times, and improve people’s satisfaction with the systems. Cognitive ergonomics can be considered as an important scientific basis for user interface design. In this study, the aim is to find out how the system’s usability can be affected by improving cognitive ergonomics. The study was conducted using the design science research approach in the context of the technology industry. The human-centered design viewpoint of technology is increasingly important in the industry context as the number of IT-related tools grows. In the study, the usability of the target company’s SAP ME system was improved with a focus on the aspects of cognitive ergonomics. As a manifestation of the research’s aim, an IT artifact, i.e., design instructions for improving usability from the viewpoint of cognitive ergonomics, was created.
De språkliga valen spelar en roll i användbarhet av ett informationssystem. När språket är begripligt och entydigt är det lättare för användaren att nå sina mål i användningen av informationssystemet. De språkliga valen blir speciellt påtagliga när ett system är avsett för en heterogen grupp användare. Ett skoladministrationssystem är ett exempel på ett sådant system, eftersom det används av många slags användare från administratörer, lärare och olika slags relaterade experter till vårdnadshavare och elever. Ett skoladministrationssystem fungerar som en samlingspunkt för skolvardagen, med både vardagliga kommunikationssituationer och flera olika fackområden såsom pedagogik, administration, ekonomi och de olika skolämnena. Vår artikel handlar om användning av termer och fraser i ett skoladministrationssystem som används i Finland på olika skolstadier för att planera, hålla kontakt och informera. Resultaten visar att termerna i användargränssnittet är allmänspråkliga och lätta att förstå.
The usability of health information systems has continued to be an issue in health informatics. Many health information systems that have been deployed worldwide have been deemed unusable, not fitting clinical workflow, and in some cases rejected by end users. Along these lines, there is also growing evidence that poorly designed user interfaces may lead to increased cognitive load, may negatively impact workflow, which could impede cognitive processes involved in decision making and reasoning. In this chapter, we describe work in applying user-centered design principles in conjunction with advances in usability engineering to improve the usability of health information systems so that they augment and support human cognition and work activities. Several approaches are described from the application of laboratory style usability testing to the use of clinical simulations conducted “in-situ” in real-world healthcare settings. These approaches can be used to improve the usability of a range of healthcare systems. As will be described the methods can be used to assess the impact of systems on healthcare cognitive processes, including impact on clinical reasoning and decision making. We also discuss how low-cost rapid usability engineering methods can be applied throughout the design and implementation cycle of health information systems to improve system adoption. In addition to this, emerging approaches to testing health information systems will be described, including remote and large-scale usability analyses.

Localisation action can be defined as a social action conducted by social "agents" to create a "Glocal" (global and local), market by producing creative, remarkable products and services with technology in a way that is socioculturally appropriate for a locale and presenting these products and services to glocal circulation. Since localisation is a multilayered, multidisciplinary and interdisciplinary phenomenon that extends to different fields from translation to marketing, from technology to sociology, from commerce to creativity, the field of localisation is a dynamic, ever-changing and transforming field that is in a hurry to keep up-to-date. This thesis aims to describe the field by examining the roles, functions, positions, transformations, conversions and investments of localisation actants from the lens of the Sociology of Translation by consulting Latour's ActorNetwork Theory (ANT) and Bourdieu's Field Theory, and their respective concepts of "actors", "actants", "networks", "forms of capital", and "conversion". The fieldwork consists of three phases: The Interview Phase, The Questionnaire Phase, and The Micro-Scaled Qualitative Corpus Phase consisting of job postings that posted on the LinkedIn network in the period between November 2023 and April 2024. Within the scope of the thesis, it has been determined that the agents in the localisation field prioritise 4 types of skill sets, namely linguistic competence, techn(olog)ical competence, communicative competence and creativity. Furthermore, actants, networks, capitals and investments within the localisation network are in a constant state of changes and conversions. These findings are the best indicators that the localisation network is a social and 'living' network.
Keywords: Localisation, Sociology of Translation, Actor-Network Theory (ANT), Forms of Capital, Conversions
Generative Artificial Intelligence (GAI) is fundamentally changing the ways of working and blurring the boundaries between human and machine-generated contents. While there is an increasing interest in the adoption of GAI systems, such as ChatGPT and DALL-E, there are also serious concerns about the copyright of the contents – the inputs or generated as outputs by the GAI systems. Such concerns need to be identified and assessed to ensure the ethical and responsible use of GAI systems. Thus, this paper aims to address the key research challenge: "how to identify and assess GAI system's copyright concerns"? In response, we propose the development of a Copyright Risk Checker (CRC) Tool. This tool has been formulated and evaluated using a recognised design science research methodology, drawing on an analysis of ten legal cases across Australia, the United Kingdom, the United States, and Europe. The CRC Tool has undergone evaluation through an experimental scenario, and the results suggest that it is suitable for conducting an indicative copyright risk check of GAI systems. The outcomes of this preliminary assessment can be further examined by expert legal advisors for an in-depth analysis. The development of the CRC Tool provides a foundation for continued research and advancement in this significant area of study.
The article looks at how readers understand legal text, which characteristics cause difficulties, and which facilitate understanding. The method used is protocol analysis. It examines a subject’s reading process, highlighting the features that affect reading and understanding. Subjects read test texts while verbalizing their reading experience, and their thinking aloud is recorded, transcribed, and analyzed. Subjects include lawyers, officials, and laypeople, and test materials contain extracts from the Finnish Inheritance Code, the Income Tax Act, and the Working Time Act. The results show the impact of different textual elements on comprehension and usability.
A systematic review is carried out of all at present accessible blood pressure applications for the working frameworks iOS and Android. We considered the quantity of recently released blood pressure applications, target user groups, acquisition cost, range of functions, languages, available interfaces, user ratings and connection among acquisition cost and user ratings. Furthermore, we analyzed regardless of whether the accessible applications serve the exceptional needs of blood pressure patients by carrying expert-based usability evaluation. We distinguished applicable watchwords, near classifications, and their determinations. In this manner, we played out the application audit dependent on the data given in the Google Play Store, the Apple App Store, and the applications themselves. Moreover, we did an expert based ease of use assessment based with respect to a representation of 10% example of blood pressure applications. An immense number of blood pressure applications as of now exist, yet the majority offer comparable functionalities and join just a single to two functionalities in one application. Patients and doctors alike ought to be associated with the application development procedure to a more prominent degree. We expect that the transmission of well-being parameters to doctors will acquire significance in future applications. The convenience of blood pressure applications for patients established was moderate to great. In any case, this outcome is connected fundamentally to applications offering a small range of functionalities. Multifunctional applications performed significantly more terribly in terms of ease of use. Besides, the presence of documentation or examination work fundamentally brought down usability scores.
