User Centered

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.

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.

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.

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.

Good products and good service derived from comprehensive understanding of user requirements. Currently, user-centered design (UCD) is mentioned very often in the field of design. However, how to achieve our design based on UCD, and how to carry out user needs throughout the whole product lifecycle? The present study showed improved design for Automated Teller Machine（ATM ）, which based on the understanding of the user research theory, establishing the model to solve the problems that the customers faced when they use the machine by analyzing the user needs.

The lack of user engagement, the absence of user feedback, incomplete and continuously changing user requirements are among the critical concerns that cause projects to fail. User-centered design (UCD) and agile software development are two iterative approaches that have been proposed to overcome such concerns. UCD is a design process focusing on user research, user interface design and usability evaluation. Introduced by software engineering practitioners, agile refers to a number of iterative and incremental software development practices that emphasize people’s needs, communication between developers and stakeholders and the ability to adapt to change. In both the agile and UCD communities, however, a full understanding of user requirements is often seen as incompatible with early and quick development iterations. We performed a literature review aiming to identify how agile teams have integrated UCD tools into their agile software development process to a better understanding of the user requirements without losing sight of the agile values and principles. UCD tools adaptations and minimal-up-front design applied in agile development are among the approaches discovered in this study. The findings could lead to a comprehensive user-centric software engineering that will overcome inherent problems faced by agile teams to understand user needs, priorities and goals.
