BACKGROUND Stressful situations during intraoperative emergencies have negative impact on human cognitive functions. Consequently, task performance may decrease and patient safety may be compromised. Cognitive aids can counteract these effects and support anesthesiologists in their crisis management. The Professional Association of German Anesthesiologists set up a project to develop a comprehensive set of digital cognitive aids for intraoperative emergencies. A parallel development for several software platforms and stationary and mobile devices will accommodate the inhomogeneity of the information technology infrastructure within German anesthesia departments. OBJECTIVE This paper aimed to provide a detailed overview of how the task of developing a digital cognitive aid for intraoperative crisis management in anesthesia was addressed that meets user requirements and is highly user-friendly. METHODS A user-centered design (UCD) process was conducted to identify, specify, and supplement the requirements for a digital cognitive aid. The study covered 4 aspects: analysis of the context of use, specification of user requirements, development of design solutions, and evaluation of design solutions. Three prototypes were developed and evaluated by end users of the application. Following each evaluation, the new requirements were prioritized and used for redesign. For the first and third prototype, the System Usability Scale (SUS) score was determined. The second prototype was evaluated with an extensive Web-based questionnaire. The evaluation of the third prototype included a think-aloud protocol. RESULTS The chosen methods enabled a comprehensive collection of requirements and helped to improve the design of the application. The first prototype achieved an average SUS score of 74 (SD 12), indicating good usability. The second prototype included the following main revisions: 2-column layout, initial selection of patient type (infant, adult, or parturient), 4 offered search options, and the option to check off completed action steps. Its evaluation identified the following major revision points: add quick selection for resuscitation checklists, design the top bar and tabs slightly larger, and add more pictograms to the text. The third prototype achieved an average SUS score of 77 (SD 15). The evaluation of the think-aloud protocol revealed a good intuitiveness of the application and identified a missing home button as the main issue. CONCLUSIONS Anesthesiology—as an acute medical field—is particularly characterized by its high demands on decision making and action in dynamic, or time-critical situations. The integration of usability aspects is essential for everyday and emergency suitability. The UCD process allowed us to develop a prototypical digital cognitive aid, exhibiting high usability and user satisfaction in the demanding environment of anesthesiological emergencies. Both aspects are essential to increase the acceptance of the application in later stages. The study approach, combining different methods for determining user requirements, may be useful for other implementation projects in a highly demanding environment.

Information visualization is a user-centered design discipline. In this article we argue, however, that designing information visualization techniques often requires more than designing for user requirements. Additionally, the data that are to be visualized must also be carefully considered. An approach based on both the user and their data is encapsulated by two questions, which we argue information visualization designers should continually ask themselves: ‘What does the user want to see?’ and ‘What do the data want to be?’ As we show by presenting cases, these two points of departure are mutually reinforcing. By focusing on the data, new insight is gained into the requirements of the user, and vice versa, resulting in more effective visualization techniques.

Implementing integrated online prevention to reduce the risk of both obesity and eating disorders, in the school setting, is a promising approach. The challenge is to develop highly user-friendly and motivating programs, to foster adherence and effectiveness. The purpose of this study was to evaluate the usability of such a universal prevention program for students aged 14–19 years, and to address engagement issues. A mixed-methods approach was chosen, consisting of a think-aloud task, a semi-structured interview, and a questionnaire including items on sociodemographic characteristics and the System Usability Scale (SUS). Usability tests were conducted in two rounds, with five adolescents participating per round. Mean score in the SUS was 92.5 of 100 points (range 85–100), in the second round, after some adaptations from the participants’ feedback. In the course of the think-aloud tasks and interviews, five major themes emerged—visual design, navigation, mode of transfer, content, and engagement conditions. Interesting headlines, gamification, and monitoring tools are crucial for engagement. Apart from the importance of using the program during school hours, the study showed that problems currently perceived as important by the target group, need to be considered and addressed, prior to offering them prevention programs, which highlights the importance of a user-centered design.

Anyelir Cake And Bakery is the largest cake shop in Purwakarta which is engaged in the production of various kinds of cakes.  In the process of distributing products from the central store to branch stores, they still use WhatsApp to place orders. This causes frequent discrepancies in the number of products requested and the number of products received due to an error in reading the message. In this study, a mobile-based application will be built that is able to manage order data more accurately. The development of this application uses the User Centered Design (UCD). This is a design method that focuses on user needs so that the final result of this application does not need to change user behavior when using the application. The UCD method consists of four stages, namely plan the human centered design, specify user and organizational requirements, product design solutions, and evaluate design against user requirements. In the development process, application testing was carried out to get feedback from users with good scores, namely an average of 4 (agree) and 5 (strongly agree). This shows that the application is in accordance with the needs of the user.

In this article we discuss ‘slanty design’, which incorporate three new principles into a conventional user-centered design process. These are designing for non-goals (things you wish the user not to be able to do); creating anti-usability (designing so that it is difficult to achieve the non-goals); and clean design (solutions without unwanted side-effects that then have to have solutions designed for them). Slanty design incorporates many of the concepts of socio-technical approaches, and is explained using a variety of examples, including an airport baggage carousel, and the remaining challenges outstanding are described.

AbstrakPerubahan gaya hidup masyarakat Indonesia sebagian sudah mengarah ke pola kehidupan modern. Peningkatan ilmu dan teknologi yang sangat berkembang pada masa kini secara tidak langsung cenderung membuat tubuh jadi kurang bergerak (low body movement). Pada zaman milenial ini olahraga sangatlah diperlukan, selain untuk menjaga agar tubuh tetap sehat, olahraga juga dapat membuat badan menjadi lebih ideal. Kini kian banyak orang yang memperlakukan yoga sebagai kebutuhan utama, bukan semata gaya hidup. Yoga ini diyakini banyak orang bermanfaat bagi kesehatan fisik dan psikis. Yoga merupakan seni olah tubuh, pernafasan, dan pikiran dalam bentuk gerakan-gerakan yang bersifat flowing, continue dinamis, ataupun gerakan yang ditahan dalam beberapa kali hitungan dan dibantu dengan olah pernafasan dan meditasi ringan. Oleh karena itu dalam penelitian ini diajukan suatu aplikasi membuat Media Interaktif berbasis mobile android gerakan yoga sebagai media pembelajaran tentang Gerakan yoga yang memiliki kemampuan dalam membantu user dan sesuai dengan kebutuhan user. Pada penelitian ini pengalaman pengguna aplikasi gerakan yoga di evaluasi dengan 2 metode yaitu User-Centered Design (UCD) dan System Usability Scale (SUS). Pada pengujian UCD dilakukan saat mulainya perancangan sebuah aplikasi, sedangkan selanjutnya aplikasi di uji kelayakan dengan menggunakan metode SUS. Hasil penelitian pembuatan Media Interaktif Gerakan Yoga berbasis mobile android memperoleh skor kelayakan sebesar 75,3% atau masuk dalam kategori B (Baik).Kata Kunci: media interaktif, yoga, aplikasi android, user centered design, system usability scale AbstractPart of the change in the lifestyle of the Indonesian people has led to modern life patterns. 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

Nowadays, sustainability is the new trend in product design and treats the environmental issues in a more spherical manner. This is achieved by considering the whole lifecycle of the product in advance. When design is implemented, this approach becomes the conceptual base for developing a great deal of products and services. Many ‘design for X’ methodologies have been developed, refined, and now they are commonly used. The current paper reviews a series of available design methodologies. It classifies them based on the life cycle stage that they are implemented. The vast majority of them have a strong focus on manufacturing issues. Even when they focus on the product-use phase, they are dominated by the manufacturer’s decisions. The users’ interaction with a product may strongly influence its environmental impact, and for this reason designers should put extra effort in order to influence this behavior. Based on this demand there is a necessity for the development of novel methodologies and tools, which would be directly related to the use phase of the products. In recent years, a design methodology called User-Centered Design (UCD) is under consideration with an aim to understand the users’ needs, goals, limitations, possibilities, previous experiences and how they are affecting the user interaction with objects. The present paper proposes a new methodology named Design for Green Usability (DfGU), which is directly linked to the user requirements during the use phase of the product.
