BACKGROUND The German Biobank Alliance (GBA) aims to establish a cross-site biobank network. For this endeavor, the so-called Sample Locator, a federated search tool for biospecimens and related data, has been developed, forming the heart of its information technology (IT) infrastructure. OBJECTIVE To ensure the sustainable use of such a tool, we included researchers as participants in an end user–based usability evaluation. METHODS To develop a prototype ready for evaluation, we needed input from GBA IT experts. Thus, we conducted a 2-day workshop with 8 GBA IT team members. The focus was on the respective steps of a user-centered design process. With the acquired knowledge, the participants designed low-fidelity mock-ups. The main ideas of these mock-ups were discussed, extracted, and summarized into a comprehensive prototype using Microsoft PowerPoint. Furthermore, we created a questionnaire concerning the usability of the prototype, including the System Usability Scale (SUS), questions on negative and positive aspects, and typical tasks to be fulfilled with the tool. Subsequently, the prototype was pretested on the basis of this questionnaire with researchers who have a biobank background. Based on this preliminary work, the usability analysis was ultimately carried out with researchers and the results were evaluated. RESULTS Altogether, 27 researchers familiar with sample requests evaluated the prototype. The analysis of the feedback certified a good usability, given that the Sample Locator prototype was seen as intuitive and user-friendly by 74% (20/27) of the participants. The total SUS score by the 25 persons that completed the questionnaire was 80.4, indicating good system usability. Still, the evaluation provided useful advice on optimization potential (eg, offering a help function). CONCLUSIONS The findings of this usability analysis indicate that the considerations regarding a user-friendly application that have been made in the development process so far strongly coincide with the perception of the study participants. Nevertheless, it was important to engage prospective end users to ensure that the previous development is going in the desired direction and that the Sample Locator will be used in the future. The user comments and suggestions for improvement will be considered in upcoming iterations for refinement.

Augmentative and Alternative Communication (AAC) techniques are employed to mediate communication with people who have communication disorders, as in cases of intellectual disability. Although there are various digital solutions that promote alternative communication options for individuals with communication disorders, only a few of them have been specifically designed or targeted to people with intellectual disability (ID). This work is motivated by the lack of AAC solutions contributing to the rehabilitation processes of individuals with intellectual disability in Brazil. The study presents a mobile-based AAC solution conceived as a tool to assist the rehabilitation process of people with ID. The design was based on user-centered design principles and accessibility standards. The System Usability Scale (SUS) questionnaire was used to evaluate the solution. Four specialists and twenty-five students participated in this study. The proposed solution shows the potential educational value for professionals who assist individuals with intellectual disability in Brazil.

System Usability Scale (SUS) is a usability testing technique for a simple system using a Likert scale. Testing and usability analysis assess user satisfaction with the system or web. So, the purpose of this service activity is to train website usability testing with SUS, using the Dukcapil website as a test object. Dukcapil's website will be analyzed for its usability level as a real case for direct practice. In SUS, ten statements are used as parameters in assessing the usability of a website. This activity was attended by 20 people, including Bina Darma University students, vocational students, and IT staff from the Dukcapil Palembang City. The usability analysis of this website aims to assess how well user interaction with the website is going. Then, the results of this assessment and study produce an input as a reference for website development to be more optimal in the future. In testing the usefulness of the Dukcapil website in this PKM activity, it can be seen that the SUS score is at a score of 56.125, with the category Acceptable. Therefore, it shows that the Dukcapil website is ranked F, with a "Good" rating category. The training results show that the Dukcapil website is still very rarely accessed by users. Because it provides information lacking in updates, the features used are still in the beta version (still in the testing phase). Users or participants still do not understand how to use it. In addition, this activity provides participants with an understanding of the website usability test using the SUS model.

Increasing science and technology, which is significantly developed today, indirectly tends to make the body less mobile (low body movement). In this millennial era, exercise is essential. Apart from keeping the body healthy, exercise can also make the body more ideal. Now more and more people treat yoga as a primary need, not just a lifestyle. Many people believe yoga to be beneficial for physical and psychological health. Yoga is the art of exercising the body, breathing, mind in flowing, continuous dynamic movements, or movements held for several counts and assisted by breathing exercises and light meditation. Therefore, in this study, an application is proposed to create interactive media based on mobile android yoga movements as a learning medium about yoga movements that can help users according to user needs. In this study, the user experience of the yoga movement application was evaluated by two methods, namely the User-Centered Design (UCD) and the System Usability Scale (SUS). The UCD test is carried out at the start of designing an application, while then the application is tested for feasibility using the SUS method. The research results on mobile Android-based Yoga Movement Interactive Media obtained a feasibility score of 75.3% or included in category B (Good).Keywords: interactive media, yoga, android application, user centered design, system usability scale

Computer programming subject is the most-feared subject by students because it is hard to learn. At present, various learning media for programming are available, therefore, the learning process which was often considered as boring and hard to learn becomes interesting and easy to do. One of those media is through internet. This condition is parallel with various number of learning-based online sites that currently grow, including CodeSaya; one of the learning websites for computer programming languages. Usability is an important aspect to be noticed for the users to feel facilitated in using it, acquiring the required knowledge, and be interested to always rely on the site within the learning process. By collecting the user perception about user interfaces, questionnaire might help identifying the weakness in website usability to perform improvements. This research was done to analyze the success of online learning site, whether it meets the usability criteria by implementing System Usability Scale (SUS) questionnaire as the research instrument. SUS is an effective and reliable instrument to measure the usability of various products and services. The research questionnaire consisted of 10 questions which disseminated toward 162 respondents divided into two groups, namely familiar users that amounted to 81 respondents and unfamiliar users that amounted to 81 respondents as well. The usability of CodeSaya site acquired 72.1 of score for familiar users and 70 of score for unfamiliar users. The score acquired from the rating given by familiar respondents only a bit higher compared to the unfamiliar respondents. The rating in alphabet resulted in B or Good. It can be concluded that this computer programming learning site has met the usability criteria, therefore, it can be implemented as a learning medium that is feasible to be used by the users.

BACKGROUND To meet the growing importance of real-word data analysis, clinical data and biosamples must be timely made available. Feasibility platforms are often the first contact point for determining the availability of such data for specific research questions. Therefore, a user-friendly interface should be provided to enable access to this information easily. The German Medical Informatics Initiative also aims to establish such a platform for its infrastructure. Although some of these platforms are actively used, their tools still have limitations. Consequently, the Medical Informatics Initiative consortium MIRACUM (Medical Informatics in Research and Care in University Medicine) committed itself to analyzing the pros and cons of existing solutions and to designing an optimized graphical feasibility user interface. OBJECTIVE The aim of this study is to identify the system that is most user-friendly and thus forms the best basis for developing a harmonized tool. To achieve this goal, we carried out a comparative usability evaluation of existing tools used by researchers acting as end users. METHODS The evaluation included three preselected search tools and was conducted as a qualitative exploratory study with a randomized design over a period of 6 weeks. The tools in question were the MIRACUM i2b2 (Informatics for Integrating Biology and the Bedside) feasibility platform, OHDSI’s (Observational Health Data Sciences and Informatics) ATLAS, and the Sample Locator of the German Biobank Alliance. The evaluation was conducted in the form of a web-based usability test (usability walkthrough combined with a web-based questionnaire) with participants aged between 26 and 63 years who work as medical doctors. RESULTS In total, 17 study participants evaluated the three tools. The overall evaluation of usability, which was based on the System Usability Scale, showed that the Sample Locator, with a mean System Usability Scale score of 77.03 (SD 20.62), was significantly superior to the other two tools (Wilcoxon test; Sample Locator vs i2b2: <i>P</i>=.047; Sample Locator vs ATLAS: <i>P</i>=.001). i2b2, with a score of 59.83 (SD 25.36), performed significantly better than ATLAS, which had a score of 27.81 (SD 21.79; Wilcoxon test; i2b2 vs ATLAS: <i>P</i>=.005). The analysis of the material generated by the usability walkthrough method confirmed these findings. ATLAS caused the most usability problems (n=66), followed by i2b2 (n=48) and the Sample Locator (n=22). Moreover, the Sample Locator achieved the highest ratings with respect to additional questions regarding satisfaction with the tools. CONCLUSIONS This study provides data to develop a suitable basis for the selection of a harmonized tool for feasibility studies via concrete evaluation and a comparison of the usability of three different types of query builders. The feedback obtained from the participants during the usability test made it possible to identify user problems and positive design aspects of the individual tools and compare them qualitatively.
