Parallel User Interface Design of a Clinical Decision-Support Application for Desktop and Pocket Pc Platforms

The Food & Beverage (F&B) industry in Indonesia is growing rapidly, yet many mobile applications still fail to deliver an optimal user experience (UX) due to unintuitive user interface (UI) designs, inefficient ordering systems, and lack of integrated payment methods. These issues negatively impact user satisfaction and application usability. This study aims to design the user interface (UI) and user experience (UX) of a mobile food & beverage application that meets user needs, accommodates industry expectations, and is evaluated for effectiveness using the User-Centered Design (UCD) approach. The research employed the UCD methodology, involving user interviews, persona development, wireframing, prototyping, and usability testing. The evaluation was conducted using the System Usability Scale (SUS) with 15 respondents. The results show that the prototype of the “KuliNow” application achieved an average SUS score of 84, categorized as “Excellent.” Key features include integrated mobile banking payments, direct communication with restaurants, social media integration, pre-order functionality, efficient order management, and a reliable review and rating system. This study demonstrates that the UCD approach is effective in developing intuitive, user-focused mobile applications.

— User interface is a term used to describe the appearance of a computer or equipment that the user interacts with. User experience isn't just what consumers see; This can not only provide a design that appeals to the eye, but can also explain why the design is the way it is, a design that can make users feel comfortable when achieving their goals when utilizing the services provided by websites and applications. The purpose of this study is to find out whether the user centered design approach has a positive impact on the analysis and design of user interface and user experience on the Inspire Portal of Sam Ratulangi University.. Researchers have received the final results, namely, the mean value in the attractiveness aspect which was initially -1.61 the value became 0.71, for the second aspect, namely perspicuity (clarity) the initial value -1.72 rose to 0.68, and for the next aspect, namely the third efficiency value before improvement -1.67 to 0.61, and the fourth aspect dependability (accuracy) value before improvement -1.64 and after improvement the value became 0.67, The fifth aspect is stimulation before the improvement of the mean value of -1.64 after improvement to 0.58 and for the last aspect, namely novelty before improvement the value is -1.69 and after improvement the value becomes 0.64. The measurement tool in this study uses a user experience questionnaire, and for the final results of the benchmark comparison there are four aspects that are below average, namely attractiveness, efficiency, stimulation, and novelty.

In recent years, the design of user interfaces and user experience has become more relevant in companies due to the need to optimize the interaction between users and complex interactive systems. This study aims to establish design guidelines to improve the user experience in engineering applications in teams of Air handling unit testing engineers. A redesign process of a handling unit testing application was conducted using a user-centered design approach through in-depth interviews, user profiling, interactive prototyping, and usability testing. The results obtained showed a significant improvement in usability and user experience by implementing the fundamentals and principles of user-centered design. This case study highlighted the fundamental role of user interface and user experience design so that user interface designers and engineers can reference the learnings and findings to improve their applications to optimize the tasks of handling unit testing engineers.

An end-use’s experience of any software is typically influenced by the interface presented by the application to the user. For Mixed Reality Environments such as Augmented and Virtual Reality, the user interface is highly visual, and a poor interface can significantly degrade the user experience. Adequate attention is required when designing or creating interfaces and user experience within Mixed Reality Environments as traditional interface design goals and specifications often need to be adjusted. Furthermore, for mixed reality environments on Mobile devices there are additional interface constraints and considerations that would considerably improve the user experience when properly addressed. This research paper discusses the evolution(s) of user interface(s) and user experience of Augmented and Virtual Reality applications on Mobile devices and contributes a framework for improving user interfaces and experience when using Mixed Reality Environments.

Information and Communication Technology (ICT) has revolutionized the lives of the people. The technology is embedded in daily life of literate or semiliterate/illiterate users. However, the user interface (UI) requirements for semiliterate/illiterate users are different from that of an educated person. The researchers of Human Computer Interaction for Development (HCI4D) face challenges to improve the usability of a UI for the semiliterate users. Therefore, a Systematic Literature Review (SLR) is conducted to provide a set of design factors and guidelines for UI development of semiliterate users. The study is based on extensive research gathered from literature to understand the user-centered design (UCD) approach, enhancing user experience (UX) for semiliterate users. This study analyses fifty two research articles that are published during 2010-2020. The findings shed light on the systematization of UI design guidelines for semiliterate/illiterate users. These guidelines can help in taking advantage of ICT during the COVID-19 pandemic. The analysis shows that seventeen main design factors are indispensable for designing UI of semiliterate users. The most suggested design factors include localization and graphics, which should be incorporated in UI for the target population. Moreover, the lag in the design factors as personalization and consistency open a road for future research.

Guidance and counseling services have an important role in moral assistance and directing students' talents and interests. The Covid-19 pandemic has hampered Counseling Guidance services because learning activities are carried out online. This study aims to conduct a UI and UX assessment of the counseling application based on the Cased Based Reasoning algorithm called B-Talk. This application was developed with a mobile platform design. Infernalities than the approach used is the User-Centered Design (UCD). The UCD approach is an approach that uses factors human, knowledge of usability techniques, and an interactive approach to developing design and systems. The UI(User Interface) and UX(User Experience) designs that have been produced will be tested with an expert assessment of Counseling Guidance which includes two aspects, namely usability testing and User Experience Question (UEQ). The media validation assessment was obtained from an average value of 89.2% of the standard feasibility without revision. In this case, it can be concluded that the B-Talk application design can be used as its function for Counseling Guidance media for adolescents.

Until recently, client-server groupware applications have been designed for desktop clients. However, the dramatic increase in the use of mobile and wireless devices combined with the explosive growth of their power now requires the exploration of alternative clients implemented on devices such as PDAs and smart phones. The goal of this thesis is to provide the users of Collaborative Virtual Workspace (CVW) with a flexible way to access, communicate, and collaborate, using mobile devices. Towards this end, this thesis develops a Pocket PC rich client for the CVW. This thesis presents the development process of a Pocket PC application as a CVW client, otherwise referred to it as the CVW rich client. Included is a discussion of the issues and challenges that arose through the development process. Finally, recommendations for future development and extensions are the last part of this thesis.

Current smart mobile devices such as Pocket PCs have become common accepted daily-life personal assistants. Such mobile devices provide much less support for visualization compared to desktop computers. When developing mobile visualization applications, one should take the limited screen size, currently available interaction tools and relatively poor computation power into consideration. We describe a visual lens toolkit integrated with Focus+Context technique and it can be incorporated into various applications on Pocket PCs. Our technique creates a distorted display view of target object in a high resolution focus area that is smoothly embedded into the distorted context. We have tested the toolkit in two applications as stylistic lens and sketch lens separately and received fine experiment results. In remote line drawing of 3D model system, the lens toolkit embedded into the client side mainly serve as stylistic lens which provide the users with different presentation styles of the model according to the current viewpoint and focus. In mobile sketch system, the lens toolkit performs like a refinement filter which adoptively turns the loose sketch or SVG file into finer image. Both tested applications.

This research project investigates the connections between user identity, product emotion and interface design. It investigates whether mobile communication devices can better reflect user identity and lifestyle through the provision of a customizable Graphical user interface (GUI) that users can actively manipulate. The study proposes a user and design-driven interaction process whereby users can easily personalize the interface of their devices to reflect their idiosyncratic needs and preferences, the designed interface making interaction more individually useful, meaningful and empowering. The project extends the scope of end user customization beyond basic cosmetic changes to the physical appearance of the GUI to the modification of the actual process of interaction. The research focuses on the capacity to employ the user interface to support more intimate and flexible patterns of use that foster personal identification and emotional investment with devices, as against those that are preordained, device-driven and technologically deterministic.

A common problem faced by technology projects is that while every effort is made to deliver at the highest quality, and ensuring well constructed business specifications, the outcome falls short of user expectations, rendering a system difficult to use, thereby negatively impacting adoption by the user. This paper highlights the need to involve the user at an early stage in the development process, using a User-Centred Design (UCD) approach and User Experience (UX) methods, and building low cost prototypes that encourage low cost optimisation, in order to mitigate the risk of later re-work, and increase the chances of holistic designs rather than incremental changes. The paper also highlights the view that a User Interface (UI) is in fact a business interface, and optimising the UI is synonymous with optimising business KPIs.

Usability of a consumer electronic product (CEP) is one of the most important factors that the users consider in purchasing a CEP as well as functionality, price, etc. This has led many companies to realize new shapes of user interfaces (UIs) and styles of interaction for CEPs, ranging from modern touchscreens to physical controls and displays of any kind. Even if the general feeling is that such increased interactivity may enhance the overall user experience, the side effect is that often a CEP’s UI provides too many functions that are difficult to learn and use without referring to the user manual, leading to many usability issues. In this paper, we leverage a case study in the CEPs sector to present a novel log-based evaluation technique in the field of Human-Computer Interaction (HCI). Our technique allows us not only to keep track of the user interactions with a CEP’s UI during its daily use, but also to understand what has gone wrong during a user interaction, detecting which user actions have caused usability issues and suggesting explanations for solving them, thus providing a crucial feedback to improve the design of the CEP’s UI next version.

The use of metaphor is essential in user interface design, particularly for the mobile landscape, as the visual environment continues to be populated with more and more mobile electronic devices. A metaphor allows us to understand one concept in terms of another. Although considerable research has gone into the mobile technology, little attention has been paid to mobile interface metaphor, which is the key to user interaction. This paper explores the role of metaphor in interfaces in facilitating user interaction with mobile devices. It presents a classification of metaphors. It also proposes a framework with salient factors in relation to visual communication with metaphors. It also offers some thoughts on the use of new metaphors.

BackgroundAging is associated with various challenges, especially concerning mobility. Transportation planning e-tools are currently available to provide older adults with real-time travel information and help them choose trip options. However, many older adults find them challenging to use, as they are not tailored to their specific needs, such as lack of accessibility to the different means of transportation. It is necessary to identify knowledge gaps about design based on older adults’ experience using transportation planning e-tools.ObjectiveThis study aims to identify knowledge gaps regarding the user experience design and its evaluation for older adults using transportation planning e-tools.MethodsA scoping review of the scientific literature was conducted, based on Arksey and O’Malley’s guidelines. The search covers sources published in English from January 2002 to October 2022 through 7 scientific databases, including MEDLINE, AgeLine, CINAHL, SCOPUS, ProQuest, IEEE Explore, and TRID (Transportation Research International Documentation), and was updated in October 2023. Data selection and extraction were performed by the first author and were co-validated by 2 co-authors. The identified sources were analyzed based on source characteristics (authors, year of publication, title of the article, source of article, country, and context of the studies), the purpose of the studies (objectives and study orientation), and the mapping of the methodology and evaluation of user experience (design approach, setting, type of data collection and analysis, type of usability evaluation, and sample size). Both descriptive-analytical methods and thematic analysis were used to analyze the categorized data.ResultsOverall, 1905 sources were identified through databases, and 40 sources were selected for full-text analysis. Data analysis revealed in recent years that there has been significant growth in e-tools designed for older adults, but only 2 studies were related to the field of transportation. In total, 12 studies aimed to evaluate user experience, and 22 studies focused on a user-centered design approach. Most of these studies (n=31) were carried out in a laboratory setting, using summative usability evaluation (user-based testing). The System Usability Scale (SUS) was the most prevalent tool (15 studies) to measure user efficiency and satisfaction. However, no studies have been found that specifically aim to improve the mobility experience of older adults using an age-friendly transportation planning e-tool in a real-life context.ConclusionsThere is a lack of studies assessing older adults’ experience when using transportation planning e-tools in real-life situations. To bridge this gap, a participatory approach is necessary to better consider the needs of older adults in a real-life context and create age-friendly design guidelines for the development of transportation planning e-tools. This will not only enhance their user experience in trip planning but also promote their social engagement by improving their mobility.
