User Experience Design

User eXperience (UX) evaluation is a challenging task, especially for newcomers and when evaluating domain related aspects. Usability and UX in virtual museums is one of our current research topics. We focused on identified users' needs, on developing a set of specific usability heuristics, and a methodology to asses UX in virtual museums. We conducted several experiments, mainly with graduate and undergraduate students in Tourism and Computer Science. The paper presents a UX study on Pre-Columbian Museum portal.

This study investigated the influence of stereoscopic visual depth and body vibration on the high-level affective perception that concerns the senses of presence and verisimilitude. The multisensory content used in our experiment consisted of the 3D video recording of a passing train as seen from the side of the railroad, binaural recording of the 3D spatial sound, and the ground vibrations caused by the train. The results showed that the augmented stereoscopic depth information enhanced the affective perception of both the presence and verisimilitude. Moreover, both the presence and verisimilitude saturated with an increase in the intensity of body vibration under the augmented perceived depth condition. However, compared to the presence, the verisimilitude tended to saturate at a lower vibration-intensity. This tendency is consistent with that reported in our previous research.

The purpose of recommender systems (RS) is to facilitate user collaboration and communication on the platform. Nevertheless, there is limited knowledge regarding the extent of this relationship and the techniques by which RS could promote persistent user engagement with the platform. In order to fill this void, the present study investigates the role of RS in transforming users' short-term engagement with the RS into long-lasting involvement with the platform. We present a theoretical framework by reviewing relevant literature in the domains of RS and user engagement to probe these issues. We provide open challenges in this field along with metrics in the present study.

This study explores the role of user interface (UI) design in shaping user experience (UX) within mobile ecommerce applications focused on kitchenware products. As online consumer behavior becomes increasingly product-specific, there is a growing demand for intuitive and visually cohesive interfaces that cater to targeted retail segments. The research aims to identify key UI elements that influence user satisfaction, trust, and usability in kitchenware e-commerce environments. A theoretical approach was employed, involving a systematic literature review of 20 scholarly articles related to UI/UX design in digital commerce. The analysis was conducted using Garrett's Five Planes Framework to map strategic and visual design elements to positive UX outcomes. The review reveals that navigation clarity, consistent layout, personalization, and responsive design are among the most impactful features that enhance user experience in kitchenware shopping apps. Although the study is theoretical, it offers valuable insights for interface designers and developers aiming to improve engagement and usability in niche retail applications. The findings also serve as a foundation for future empirical studies, contributing to the refinement of user-centered design practices in the context of specialized e-commerce platforms.

Rapid Application Development (RAD) menjadi salah satu pilihan alternatif dari System Development Life Cycle yang belakangan ini sering digunakan untuk mengatasi masalah keterlambatan yang muncul ketika menerapkan metode tradisional. Keunggulan dari penggunaan metode ini mencakup kecepatan, akurasi, serta biaya yang lebih terjangkau dibandingkan metode konvensional. Selain itu, melibatkan pengguna dalam proses perancangan membuat kebutuhan mereka dapat terpenuhi secara optimal, yang pada gilirannya meningkatkan kepuasan pengguna terhadap sistem. Namun, saat menerapkan metode Rapid Application Development, penting untuk memperhatikan beberapa faktor, khususnya kesiapan tim, ruang lingkup sistem, kebutuhan pengguna, dan performa sistem. Pada akhirnya, sebagai salah satu pilihan dalam System Development Life Cycle, Rapid Application Development dapat dijadikan pedoman untuk menghasilkan sistem informasi yang sesuai dengan kebutuhan pengguna.

Prototyping merupakan salah satu metode pengembangan perangat lunak, yang berupa model fisik kerja sistem dan berfungsi sebagai versi awal dari sistem (Ogedebe, 2012). Metode prototyping menghasilkan model sistem yang dapat digunakan oleh pengguna dan para pengembang sistem informasi agar dapat berinteraksi, hal ini bertujuan untuk menghasilkan adanya umpan balik (feedback) dari pengguna sistem. Feedback yang dihasilkan oleh pengguna dijadikan sebagai bahan pertimbangan dalam perancangan model sistem informasi sebelum dilakukannya pengembangan penuh, dengan kata lain prototype dapat dihilangkan atau ditambahkan beberapa fitur-fiturnya sesuai perencanaan dan analisis oleh pihak pengembang sampai dengan tahap uji coba sehingga menghasilkan model sistem informasi yang sesuai dengan kebutuhan awal pengguna. Metode Prototyping Pengembangan sistem informasi menggunakan metode prototyping dilakukan berdasarkan empat fase utama. Menurut Rosa (2013), prototyping dimulai dengan proses pengumpulan kebutuhan, melibatkan pengembangan dan pengguna sistem untuk menentukan tujuan, fungsi dan kebutuhan operasional sistem.

Dengan demikian, Design Thinking menjadi pendekatan ideal untuk menghadirkan solusi inovatif, adaptif, dan berorientasi pada pengguna dalam pengembangan sistem informasi berbasis komputer.

The visual style in a game is an aspect of user experience that is often neglected in user experience studies. Visual style is reflective of the tone that a game designer intends to convey or the assumption of what the intended audience would prefer, and it is an important aspect of how a player experiences a game. This paper reports a study that investigated the effect of two elements of visual style, e.g. form and color, on user's moment and memory-based experiences (engagement and enjoyment). While the impact of color and form on experience is inconclusive, visual preference by a player does appear to be indicative of whether or not the player will be engaged and enjoy an experience. In order to control the experience, the game being used for this study was created by one of the authors.

The Egyptian Government published several digital services through their websites; however, the number of interactive users is very limited compared to the country's population and the expected users. This research is intended to figure out the user experience design challenges impact on the end-user to improve the efficiency of the GOV’s website, and this will help the government to improve the quality standard of the digital services before publishing the services to the Egyptian citizens.

As AI-driven recommendation systems become increasingly pervasive across digital platforms, public discourse often focuses on the content being delivered. However, this research argues that the behind-the-scenes processes, commonly referred to as the "algorithmic black box," contain hidden narratives disseminated through what we term "black semiotics."
This study aims to deconstruct these narratives by analyzing non-verbal and non-visual elements in interaction design, algorithmic architecture, and feedback patterns. By applying the theoretical framework of black semiotics, we demonstrate how these "invisible symbols" actively manipulate perception, shape behavior, and subtly direct user experience.
Through qualitative analysis of three major platforms (YouTube, TikTok, and Instagram), we reveal how algorithmic systems don't merely recommend content but actively construct and constrain the narratives available to users. Our findings highlight the importance of shifting research focus from what is recommended to how algorithms shape digital reality, paving the way for a more critical understanding of user autonomy in the AI era.
The research introduces the concept of "black semiotics" as a new theoretical framework for understanding hidden semiotic dimensions of algorithmic systems, contributing to critical algorithm studies and digital culture research.

The rapid advancement of digital technology has transformed healthcare services, including the implementation of online registration systems in hospitals. RSUP Surakarta has operatedan online patient registration system since 2021 to reduce wait times and improve service efficiency. However, no formal evaluation has been conducted from the user experience (UX) perspective. This study aims to evaluate the UX of RSUP Surakarta’s onlineregistration system using the User Experience Ques-tionnaire (UEQ) method. A descriptive quantitative approach was employed with accidental sampling involving 100 respondents who had used the system in 2024. The UEQ measured six aspects: Attrac-tiveness, Perspicuity, Efficiency, Dependability, Stimulation, and Novelty. Results revealed that all as-pects scored positively, with Attractiveness (1.920) and Dependability (1.810) reaching the “Excellent” benchmark.  Perspicuity  (1.863)  and  Efficiency  (1.868)  also  showed  strong  scores,  while  Stimulation (1.693) and Novelty (1.130) scored lower in the “Good” category. These findings suggest that although the system is well-received, improvements are necessary in terms of user engagement and innovation. Enhancing the user interface and enriching system features are recommended to optimize user satis-faction and ensure alignment with patient-centered service standards. This study contributes to digital service evaluation practices in public healthcare by providing empirical insights into user perceptions and expectations.

In user experience design, prototypes are an indispensable tool for early diagnosis of usability issues. Designing usability testing to accommodate a prototype's limited interactivity is essential to obtain relevant participant feedback. Hotspot Highlighting is a technique employed by all prominent prototyping tools to allow usability testers to see which areas of the prototype are clickable. The current body of knowledge lacks definite answers on how highlighting impacts usability testing results, compared to scenarios where participants complete tasks fully on their own. Can studies be treated the same, regardless of whether Hotspot Highlighting is enabled? What are the recommendations for how and when Hotspot Highlighting can or should be used? To investigate, we conduct a between-subjects experiment with 80 participants and 240 task completions in which we compare user behavior depending on the presence of Hotspot Highlighting. Its results indicate that Hotspot Highlighting can affect participant behavior before and after a highlight is displayed, leading to potentially different usability findings if left unaccounted for. The guidance of highlights changes the targets of clicks and encourages cognitively efficient finding of solutions by intentionally triggering the highlights. Considering the potential of Hotspot Highlighting to facilitate the usability testing of prototypes with limited interactivity, we discuss potential adaptations of the technique that address its current issues for more methodologically sound usability evaluation.

Tree testing is an established user testing method applied by software professionals to validate that an information architecture is logically navigable by users. We identify a methodological gap caused by previously unexamined non-uniformity between tree testing methods and software. Objective: To reveal the role of the user interface representations in tree testing, this research compares the results of 3 commonly-used tree testing variants. To assess how indicative they are of the user's interaction with an information architecture implemented in an actual user interface, and to issue methodological recommendations, comparison with varied high-fidelity prototypes was performed. Methods: Two between-subject studies were conducted to obtain a new dataset of users navigating an information architecture in tree testing and in interactive user interface prototypes. Data from 180 participants and 1800 task completions between 6 experimental conditions-3 tree testing and 3 prototype user interface variants-was evaluated quantitatively and qualitatively. Results: Significant differences were found between results yielded by different tree testing method variants, and in how well they approximate user navigation in the same information architecture in high-fidelity prototypes. Implications for selection of the tree testing variant are proposed in the context of evaluated information architecture, with plausible broader applicability for tree testing methodology. Evidence supports the tree testing variant with highest visibility of previous navigation choices and direct controls over their reversal as the most accurate. Conclusion: Presented findings can contribute to the design of software information architecture based on more accurate early validation, owing to tree testing that simulates less artificial user behavior more reflective of the user's navigation in the eventual user interface. We hope this will further the discussion and research leading to more holistic tree testing methodologies in the future.

The university-industry collaborations are of considerable significance for the multifaceted and sectoral industrial design discipline. It is one of the most crucial sources for students to obtain ideas and information about which sector they will turn to during their education process. The inclusion of these resources in industrial design education is effective in the student's competence acquisition as well as orientations. We observe that these collaborations, which are the focus of industrial design education in Türkiye, take place in activities, such as project courses, workshops or competitions. To contribute to the development of these models, this study revealed the contributions of the University-Industry cooperation stakeholders and the learning from a descriptive perspective of design educators. The design and design processes of the workshop, which involved 30 students forming six teams, were made and finalized in line with the relevant literature. This study aimed to provide two main contributions: supporting teamwork in educational processes and creating professional interfaces in industrial design. With the experiences gained, a sustainable and collaborative model has been proposed for implementation and development in industrial design education processes.

This article aimed to analyse awareness level, frequency of usage, ease of usage about the selected Mobile Healthcare Apps and examined impact of Service Quality of mHealthcare Apps, Satisfaction level of mHealthcare Apps, and Price level on Trustworthiness of mHealthcare Apps. This comparative research has surveyed 111 users of mobile Healthcare Apps in Bengaluru, India using structured questionnaire. The sampling techniques adopted are snowball sampling technique. The collected data analysed using Descriptive Analysis, Weighted Rank Method, Comparative Analysis, Correlation and Simple Linear Regression Analysis. Key findings reveal Apollo 24/7 as the frontrunner in terms of brand awareness and perceived ease of use. Service quality emerged as a primary determinant of trustworthiness, surpassing price value. The developed regression model effectively explains a significant portion of the variance in trustworthiness. These insights are particularly relevant for managers and developers of mHealth apps, as they emphasize the importance of maintaining high service quality to build and sustain trust among users. These findings underscore the importance of service quality in fostering trust among users of mobile healthcare apps. While the study provides valuable insights into consumer perceptions and behaviors, its reliance on snowball sampling necessitates cautious interpretation of results. The use of snowball sampling introduces potential selection bias, and the relatively small sample size restricts the generalizability of the findings. Future research could expand on this study by conducting comparative analyses across different regions to explore how cultural differences influence trust in mHealth apps. Additionally, qualitative studies could provide deeper insights into user experiences and the underlying factors that drive trust or distrust in these applications.

Museums and Design Practices explores the increasingly critical role that design is playing in museums by focusing on how human-centred design approaches are being embraced and incorporated into their work practices. This book advances 'design-as-practice' as a way to acknowledge the technosocial dimension of the working culture of cultural organisations. It reveals how designing is a situated phenomenon that enables museums and galleries to respond in a digitally mature way to emerging contexts and challenges of digital transformation. The original thesis forwarded by the authors is reinforced by reflections shared by leading museum practitioners and designers on the complex and multifaceted nature of human-centred practices found in museums and the various ways they function within their organisational working cultures. The infusion of design into all levels of museum practice demonstrates the capacity to transform how museums approach visitor experience, inclusive collaboration, and knowledge sharing in order to build resilience in the face of change and respond to the 'wicked problems' confronting cultural organisations today. Museums and Design Practices is for students and researchers as well as museum practitioners-especially those keen to understand emerging relationships that are forming between digital technology, design and the cultural work of museums. It will also be of interest to researchers and students working in the fields of design, digital culture, and museum studies.

User experience (UX) research focuses in large part on how users subjectively evaluate digital products, services, and software. In the mobile computing domain, however, UX researchers currently face limitations in the multifaceted measures that they can apply to assess specific mobile device and software combinations. Currently available measures can produce only single-score usability measures (e.g., the well-known system usability scale and its variants) or cover only a part of the mobile device-software user experience (e.g., the recently developed mobile application usability instrument). This paper adds two multifaceted survey instruments to the toolkit of UX researchers and practitioners: the mobile user experience (MUX) instrument, a 15-item instrument tailored toward scholarly research, and the short-form sMUX, a six-item instrument intended for use in practical settings or other situations where survey length is constrained.

An interactive web tool, the DecideGuide, is developed to support case managers in facilitating shared decision making in care networks of people with dementia. The DecideGuide is developed in collaboration with the end users: people with dementia, informal caregivers, and case managers. The development consisted of five sub studies. In retrospection, reflections are made on these sub studies. Lessons learned concerned: the importance and value of involving people with dementia in the development of assistive technology such as the DecideGuide, the importance of involving people with dementia from the start, the importance of taking time for people with dementia, and the importance of being aware about the role of end users from the very beginning. Moreover, developing an interactive tool for end users with different capacities and interests requires attuning to the most vulnerable end user group of people with dementia; just ask them rather than decide for them. This paper provides...

Decision Making (SDM) in dementia is complex. This is caused by the increasing cognitive decline associated with dementia and the number of involved people (people with dementia, informal caregivers and case managers). The aim of this study is to identify design issues in developing a user-friendly IT application facilitating Shared decision-making in dementia. Data collection in this study with an iterative participatory design based on the CeHRes roadmap included: focus group interviews with people with dementia, informal caregivers and case managers; a cognitive walkthrough with researchers; and a first usability test with case managers. This resulted in a list of issues addressing the quality of the system, content and service and a revision of the tool before informal caregivers and people with dementia will be invited to participate in usability tests.

People with dementia are confronted with many decisions. However, they are often not involved in the process of the decision-making. Shared Decision-Making (SDM) enables involvement of persons with dementia in the decision-making process. In our study, we develop a supportive IT application aiming to facilitate the decisionmaking process in care networks of people with dementia. A key feature in the development of this SDM tool is the participation of all network members during the design and development process, including the person with dementia. In this paper, we give insight into the first phases of this design and development process in which we conducted extensive user studies and translated wishes and needs of network members into user requirements.

This paper presents a subjective image quality experiment design that specifically targets understanding consumer perception of visual quality. With this consumer-oriented goal in mind, images were captured from a large number of representative consumer devices. This design choice is fundamentally different from previous work in the field, in that it is not based on simulated software impairments, but rather on naturally occurring artifacts due to the device and conditions. New subjective questions were posed, which allowed exploration of differences in the quality of experience (QoE) provided by various devices. This paper presents the experimental design implemented to capture ratings and feedback on these consumer devices. The study is analyzed to highlight and demonstrate the unique capabilities provided by this method.

In this paper a study on a web based tool is described that is used to keep track of attendance and work schedules by employees and managers in large companies. Ten users particpated in a think aloud test measuring the usability of a new version of the software and the user experience was measured before and after each user test. The user experience results show that the group of questions that measure the personal growth of the user got the lowest scores for this product, but pragmatic attributes, hedonic identification and attraction got much higher scores. It is not surprising that pragmatic issues get high scores for a task oriented software like this one, but it is an interesting result that the users value highly the attraction and hedonic identification.

The Institute of Distance Learning-KNUST offers courses through distance education. The mode of delivery of DL programmes in KNUST is predominantly by print medium. Two print materials, EE 287 Circuit Theory and GE 183 Principles of Land Surveying are among the twenty-five print materials used to facilitate learning in Computer Engineering and Building Technology programmes. Though current print media used by learners in the undergraduate programmes has contributed to learning by students, however, they have provided challenges to learners. Learners have reported on gaps in the learning materials thus making utilisation difficult. In order to identify and meet the needs and grievances of students relating to the suitability of course materials, the study sought to assess the quality of two print media for undergraduate studies in Computer Engineering and Building Technology programmes in KNUST. A structured questionnaire was used to collect data from students offering Computer Engineering and Building Technology programmes. The results of the study provide ample evidence to show that instructional materials assessed are about appropriate and useful. Hence there is room for improving current print materials used by DL. It also reveals the lack of female participation in the two courses and suggest an improvement of the situation through gender awareness and promotion activities at all levels of DE programming.

This case study details the methodologies we used to create a gamified library orientation experience through an iterative design process involving the phases of empathize, define, ideate, prototype, and test. For libraries with staff skilled in basic HTML and graphic design, gamified experiences are possible when they approach them with a design-thinking mindset. In designing the gamified orientation experience, we used a minimal amount of coding and conducted usability testing with playtesters prior to launch. We describe a sequence of issues we encountered during playtests, and we discuss remedies we took to balance storyline, content, educational objectives, and gameplay.

In this paper, we present the design and implementation of FocusVR, a system for effectively and efficiently reducing the power consumption of Virtual Reality (VR) devices by smartly dimming their displays. These devices are becoming increasingly common with large companies such as Facebook (Oculus Rift), and HTC and Valve (Vive), recently releasing high quality VR devices to the consumer market. However, these devices require increasingly higher screen resolutions and refresh rates to be effective, and this in turn, leads to high display power consumption costs. We show how the use of smart dimming techniques, vignettes and color mapping, can significantly reduce the power consumption of VR displays with minimal impact on usability. In particular, we describe the implementation of FocusVR in both Android and the Unity game engine and then present detailed measurement results across 3 different VR devices -- the Gear VR, the DK2, and the Vive. In addition, we present the results of ...

The role of university administrators in the use of social media within higher education institutions remains an underexplored area of academic research. While much of the existing literature has focused on students' and faculty members' engagement with social media-examining its implications for learning, teaching, and academic identity, there is limited understanding of how administrators adopt and govern social media in their institutional roles. This study aims to fill that gap by investigating the practices, perspectives, and decision-making frameworks university administrators employ when using social media in professional contexts.

User experience (UX) is not a static phenomenon; the way we interact with the technologies is dynamic which evolves over time. Ignoring this temporal nature of UX we cannot fully understand user experience. A longitudinal experiment was conducted over four weeks following 15 individuals using one of four medial players in their daily lives to examine users' behavior in prolonged use case and to investigate which factors have what type of impact on users' overall judgments at different point of time. Our analysis suggests that even if non-instrumental (e.g. Aesthetics of interface) quality plays an important role to form users overall judgments during the initial interaction, in prolonged use cage instrumental qualities (i.e. usability, functionality) become more influential.

Information technologies exist to enable us to either do things we have not done before or do familiar things more efficiently. Metaverse (i.e. extended reality: XR) enables novel forms of engrossing telepresence, but it also may make mundate tasks more effortless. Such technologies increasingly facilitate our work, education, healthcare, consumption and entertainment; however, at the same time, metaverse bring a host of challenges. Therefore, we pose the question whether XR technologies, specifically Augmented Reality (AR) and Virtual Reality (VR), either increase or decrease the difficulties of carrying out everyday tasks. In the current study we conducted a 2 (AR: with vs. without) × 2 (VR: with vs. without) between-subject experiment where participants faced a shopping-related task (including navigating, movement, hand-interaction, information processing, information searching, storing, decision making, and simple calculation) to examine a proposed series of hypotheses. The NASA...

This position paper examines potential pitfalls on the way towards achieving human-AI co-creation with generative models in a way that is beneficial to the users' interests. In particular, we collected a set of nine potential pitfalls, based on the literature and our own experiences as researchers working at the intersection of HCI and AI. We illustrate each pitfall with examples and suggest ideas for addressing it. Reflecting on all pitfalls, we discuss and conclude with implications for future research directions. With this collection, we hope to contribute to a critical and constructive discussion on the roles of humans and AI in co-creative interactions, with an eye on related assumptions and potential side-effects for creative practices and beyond.

The objectives of the study were to determine the interplay that exists between UX and UI design influence user engagement and learning outcomes in e-learning platforms and to establish the implications of defining UI as a distinct discipline versus a subset of UX on the design processes and collaborative practices within digital product teams. The study employed a qualitative research design with an interpretive philosophy to understand the subjective and socially constructed meanings expressed about the phenomenon under investigation. The study collected data using openended questionnaires from designers. The gathered data sheds light that UI is simply a by-product of good UX, which firmly places it under the UX umbrella. UX strategy, user research, information architecture, usability testing, and visual problem-solving for the user are all fundamentally focused on the user and UX cannot be separated from all the stages of the design process. The findings also revealed that designers should stop saying UI/UX since they are two different areas; hence, this shows that they don't understand the discipline. In response to this study's limitations, recommendations for future research were also addressed.

Creating an object-oriented design from user requirements, given as a set of use-cases, means deriving a detailed class structure that can support an implementation of those requirements. We introduce here the Augmented Finite-Stat e (AFS) model for a set of use-cases. An AFS model of a single use caseU incorporates the inputs, outputs, and operations for each interaction in U , including the ”internal” dataflows among those interactions. The AFS model for a set of use-cases U combines the AFS models of individual use-casesUj ∈ U to account for common interactions amongUj ’s and the control-flows among Uj ’s. After we decompose the combined model into a unique set of disjoint Maximal Linear Segments (MLSs), we derive one cl ass from each MLS and finally create the class-hierarchy based on the next-relationship among the MLSs.

Designing digital media for museums is no longer about the tech “nology or functionality alone but also about the experiences it delivers to diverse visitors. In chapter 7, Lisa Wright describes some of the ways in which museums are using digital technologies to enhance people’s connection with collections, with each other, or with research, ideas, and stories. Those include mobile applications, augmented and virtual reality experience, digital multisensory technologies, and more basic digital interactives (also called “interactives”)—such as a touch table or a video game.  Many of these experiences are developed through a process called visitor experience design (VX design) in which design is not just about the form of an object or system, but instead a dynamic method of thinking that places the visitor at the center of the design process. VX design is premised on the idea that a successful experience is the result of understanding and responding to visitor needs, behavior, and expectations. In this aspect, VX design is not specifically for a digital experience, but can also be applied to any aspect of exhibition design. Rather than focusing on a specific technology and what it can do, VX design aims to facilitate or enhance an interaction: the design of the interaction determines the quality of the visitor experience. This chapter focuses specifically on the VX design approach, which guides the discovery, creation, and development phases of a digital project. I begin by describing certain principles that characterize VX design. I then explore the levels of design that need to be considered in a digital project—working from visitor experience toward the concrete visual design of the interface. Finally, I provide a step-by-step guide to the VX design process, including sample design techniques.

Open Internet is an open source science data analytics qualitative research on the public and private nature of the internet and its due rule of law (RoL) regulatory compliance to the United Nations Universal (UN), under its 'Declaration of the Human Rights (UDHR)' and 'Sustainable Development Goals (SDGs)', open standards for social solidarity economy (SSE). It is being developed through years of cooperation with the World Wide Web Consortium (W3C), Internet Governance Forum (IGF), and Creative Commons (CC) and published due to a request of the International Telecommunication Union (ITU) and United Nations Conference on Trade and Development (UNCTAD) World Summit on Information Science (WSIS) during eWeek. Its purpose is the development of an open internet welfare state.
