Nuotolinio bendravimo ir bendradarbiavimo priemonės – tai Web 2.0 aplinkos, leidžiančios naudotojams sąveikauti, kurti turinį ir juo dalintis. Šiose priemonės naudotojai nebe pasyviai vartoja pateiktą informaciją, o sukuria didžiąją dalį turinio. Trimačiai virtualieji, priklausantys nuotolinio bendravimo ir bendradarbiavimo priemonių grupei, išsiskiria navigacine sistema, naudotojo atliekamomis užduotimis ir naudotojų bei virtualių objektų sąveikos būdais. Tradicinės programinės įrangos panaudojamumo vertinimo metodikos neapima šių specifinių virtualiųjų pasaulių apsektų, todėl magistro baigiamajame darbe atlikta išsami nuotolinio bendravimo ir bendradarbiavimo priemonių panaudojamumo analizė, kurios pagrindu kuriama trimačių virtualiųjų pasaulių panaudojamumo vertinimo metodika. Kuriant šią metodiką taip pat panaudoti atlikto naudotojų patirčių tyrimo rezultatai. Aprašytas euristinis vertinimas taikytas pasirinktiems trimačiams virtualiesiems pasauliams ir tokiu būdu metodikos aktualumas pagrįstas ne tik teorinėmis prielaidomis, bet ir praktinio tyrimo rezultatais. / Online communication and collaborations tools are Web 2.0 applications, which allows users’ interaction, content creation and sharing. In contrast to websites where users are limited to the passive viewing of information, these tools are dependent on content which is created by users. Online virtual worlds belongs to the group of online communication and collaborations tools and distinguishes by navigational system, user tasks and manners of interaction between users and objects. Traditional methodologies do not cover these specific aspects. Therefore this paper presents the thorough analysis of online communication and collaboration tools usability. On the basis of this analysis, there is a methodology created for evaluation online virtual world’s usability. Development of this methodology required the results of literature review analysis and performed users experience research. Described heuristic assessment was applied for chosen online virtual worlds, thus the relevance of methodology was reasoned not only by theoretical assumptions, but by results of practical research as well.

The aim of this project was to investigate what information is critical to convey to nurses when performing digital triage. In addition, the project aimed to investigate how such information could be visualized. This was done through a combined user research and machine learning approach, which enabled for a more nuanced and thorough investigation compared to only making use of one of the two fields. There is sparse research investigating how digital triaging can be improved and made more efficient. Therefore, this study has contributed with new and relevant insights. Three machine learning algorithms were implemented to predict the right level of care for a patient. Out of these three, the random forest classifier proved to have the best performance with an accuracy of 69.46%, also having the shortest execution time. Evaluating the random forest classifier, the most important features were stated to be the duration and progress of the symptoms, allergies to medicine, chronic diseases and the patient's own estimation of his/her health. These factors could all be confirmed by the user research approach, indicating that the results from the approaches were aligned. The results from the user research approach also showed that the patients' own description of their symptoms was of great importance. These findings served as a basis for a number of visualization decisions, aiming to make the triage process as accurate and efficient as possible.

因應行動政府的發展趨勢，美國、加拿大、印度、阿拉伯聯合大公國、我國政府都相繼提出發展行動政府網頁時的設計準則，然而各國政府所提出來之行動政府網頁設計規範相當混亂不統一。因此，本研究將各國政府單位所提供行動網頁設計準則統合整理成七大面向共46條的設計準則。另ㄧ方面，過去許多有關網站設計準則之相關研究，大多使用問卷了解使用者感受，皆無法判斷其準則對資訊尋求的真正影響。因此，本研究以臺北市政府觀光傳播局建置之「臺北旅遊網」為資訊尋求實驗網站，以程式記錄器記錄使用者在執行資訊尋求任務時，實際使用準則之行為歷程記錄為客觀資料，以及資訊尋求任務完成後所進行使用者認知行動政府網頁準則對於資訊尋求之重要性問卷調查為主觀資料，探討影響行動政府網頁資訊尋求速度與資訊尋求完成度之主要準則為何，以作為行動政府網頁設計之考量，以提升網站之資訊尋求效能。 本研究之研究結果顯示：(1)合計有七項使用者無法實際操作卻被認知重要之行動政府網頁設計準則；(2)合計有九項使用者可實際操作之行動政府網頁設計準則，可用操作次數預測資訊尋求達成度；(3)合計有十四項使用者可實際操作之行動政府網頁設計準則，可用操作次數預測資訊尋求速度；(4)合計有十項使用者可實際操作之行動政府網頁設計準則於資訊尋求時頻繁被使用，並且具有一定重要性；(5)合計有四項使用者可實際操作之行動政府網頁設計準則有助於提升同時提升使用者資訊尋求速度與達成度；(6)使用者資訊行為研究有必要以問卷及使用者行為記錄並行評估。 最後，本研究考量可實際操作之行動網頁設計準則之實際使用歷程操作狀況、資訊尋求時間、資訊尋求完成度及受測者認知準則重要度之行為特性，透過SOM分群方法歸納出七群影響資訊尋求速度與達成度之準則特性，並據此提出對於行動政府網頁設計者，使用準則時之參考依據，亦提出未來可供繼續探討之研究方向。 / To cope with the development trend of mobile government, the USA, Canada, India, United Arab Emirates, and domestic governments have proposed the design criteria for developing mobile government information webpage. Nevertheless, the design specifications of mobile government information webpage are chaotic and not uniform. For this reason, design criteria of mobile information webpage provided by various governments are integrated into 7 dimensions and 46 articles in this study. On the other hand, most past research on web site design criteria tried to understand user experience with questionnaire survey, which could not really judge the effect of the criteria on information seeking. As a result, “Travel Taipei”, established by Department of Information and Tourism, Taipei City Government, is utilized as the experimental web site for information seeking in this study. Programmable recorders are used for recording user behavior course of the criteria for information seeking as the objective data; and, the questionnaire survey of users’ perceived importance of the criteria of mobile government information webpage to information seeking as the subjective data. It intends to discuss the major criteria for the information seeking speed and information seeking completion of mobile government information webpage for the design of mobile government information webpage to enhance the information seeking efficacy of web sites. The research results are concluded as following. (1) There are 7 design criteria of mobile government information webpage which are not actually operated by users, but are considered important. (2) There are 9 design criteria of effective mobile government by predicting information seeking completion with operation behavior. (3) There are total 14 design criteria of effective mobile government by predicting information seeking speed with operation behavior. (4) There are 10 design criteria of mobile government information webpage which are used by most users for information seeking and present certain importance. (5) There are 4 design criteria of mobile government information webpage which could simultaneously enhance information seeking time and completion. (6) It is necessary to study users’ information behavior with questionnaire survey and user behavior records for the evaluation. Finally, the behavior characteristics of information seeking completion, information seeking time, and participants’ perceived criteria importance in the actual use of course operation of mobile information webpage design criteria which could be actually operated are taken into account in this study. Seven criteria characteristics to influence information seeking speed and completion are organized through SOM clustering, and, based on which, reference for the use of criteria are provided for mobile government information webpage designers and future research directions.

The diploma thesis describes the design of your own web application within the long-term collaborative project co.llaborate.online. In a small team, we reflect on our own workflow and designer work. Currently, the common goal is the design and development of MVP for processing text, images and other graphic material into any graphic output - graphic editor co.design. As part of the project, we have also focused for a long time on the concept of compatible MVPs for text editing or data management and user research. The starting point of co.llaborate.online is the principle of DRY (Don't repeat yourself) and the principles of web technologies. We test how certain workflows can be automated and facilitate the collaboration of designers, text authors, editors, proofreaders, etc., or emancipate users from unnecessary activities.

This thesis investigates the use of Artificial Intelligence, specifically the Large Language Model (LLM) application ChatGPT in the context of qualitative user research, with the goal of enhancing the user research interview analysis process. Through an empirical study where ChatGPT was used in the process of a typical user research insight analysis, the limitations and opportunities of the AI tool are examined. The study's results highlight the most significant insights from the empirical investigation, serving as examples to raise awareness of the implications of using ChatGPT in the context of user interview analysis. The study concludes that ChatGPT has the potential to enhance the interpretation of primarily individual interviews by generating well-articulated summaries, provided their accuracy can be verified. Additionally, ChatGPT may be particularly useful in low-risk design projects where the consequences of potential misinterpretations are minimal. Finally, the significance of clearly articulated written instructions for ChatGPT for best results is pointed out.

User Interface Design is the center concept of this thesis. It was used throughout this thesis in order to remedy the design issue of a product called Loredge. Loredge was a digital document reader that contained a Library page with a very simple design. The ultimate goal was to create design suggestions that provides users with a lot of convenience in navigating items for Loredge’s Library page. The solution was proposed by introducing the design process and the concept of Human-Centered Design, which were the essentials in compliance with Loredge users’ desires. The end results demonstrated some interesting facts about users that researchers did not think about at the beginning, which was very helpful to recognize what users want the most for themselves. Despite some predictable answers, the outcome indeed gave the problem a potential solution. The solution was to introduce categories/groups to users and design for menus and buttons that helps user filter out the items they want to navigate. This was implemented to digital mock-ups using a wireframing tool called Axure. The mock-ups could be found within this degree project. / Användargränssnitt är centrumkonceptet för denna avhandling. Det användes under hela denna avhandling för att avhjälpa designproblemet av en produkt som heter Loredge. Loredge var en digital dokumentläsare som innehöll en bibliotekssida med en mycket enkel design. Det ultimata målet var att skapa designförslag som ger användarna mycket bekvämlighet i navigeringsdokument för Loredges bibliotekssida. Lösningen föreslogs genom att introducera designprocessen och konceptet Human-Centered Design, vilka var nödvändiga i enlighet med Loredge-användarnas önskemål. Slutresultatet visade några intressanta fakta om användare som forskare inte tänkte på i början, vilket var till stor hjälp för att känna igen vad användarna vill ha mest för sig själva. Trots vissa förutsägbara svar gav utfallet verkligen problemet en potentiell lösning. Lösningen var att introducera kategorier / grupper till användare och design för menyer och knappar som hjälper användaren att filtrera ut de dokument som de vill navigera. Detta implementerades för digital mock-ups med hjälp av ett wireframing verktyg som heter Axure. Mock-ups kunde hittas inom detta examensarbete.

[pt] Atualmente a pesquisa com usuários vem ganhando projeção como diferencial no desenvolvimento de produtos e serviços de interface digital, incluindo atividades que envolvem análises e observações no contexto de uso, feedbacks e avaliações. O usuário, que anteriormente era um coadjuvante, passou a ter destaque como ator principal, tornando-se peça-chave no levantamento de requisitos de um produto, em meio a um mercado competitivo em constante transformação. Pela necessidade de adequação a frequentes mudanças, a agilidade se tornou um elemento essencial, como processo alternativo de desenvolvimento. Desse modo, uma metodologia ágil foi adotada como forma de suprir a demanda pela rapidez no lançamento dos produtos, modificando profundamente a maneira como eles são estruturados e desenvolvidos, influenciados principalmente pelo fator tempo. Consequentemente, as atividades que envolvem pesquisas, ideações e avaliações tem o tempo reduzido, comprometendo a pesquisa com usuários e a aplicação dos princípios do Design Centrado no Humano. Diante disso, a presente pesquisa tem como objetivo investigar a pesquisa com usuários em consonância com a aplicação de metodologias ágeis no desenvolvimento de produtos digitais. Através da pesquisa bibliográfica, foi permitido aprofundar os conceitos sobre o design centrado no usuário, seus princípios, as metodologias associadas e seus processos, e relacioná-lo às metodologias ágeis. Mediante as entrevistas, foi possível, também, o entendimento sobre os problemas enfrentados pelos profissionais de UX na aplicação das práticas de design centrado no usuário nas organizações, gerando insumos para aplicação de um questionário online que produziu uma compreensão e análise sobre as atividades relacionadas à pesquisa com usuários na aplicação das metodologias ágeis nas empresas do mercado brasileiro. Esta pesquisa revela como os profissionais de UX aplicam as atividades que envolvem a pesquisa com usuários em conjunto com as metodologias ágeis de acordo com a amostra coletada, evidenciando as influências no desenvolvimento dos produtos segundo as características organizacionais apresentadas. / [en] Currently, user research has been gaining a projection as a differentiator in the development of digital interface products and services, including activities that involve analysis and observations in the context of use, feedback and evaluation. The user, who was previously a supporting actor, has become a major player, key in the product requirements specification, in the midst of a competitive market in constant transformation.. Due to the need to adapt to frequent changes, agility has become an essential element as an alternative development process. This way, an agile methodology was adopted as a way of supporting the demand for speed in the launch of products, thus, deeply modifying the way they are structured and developed, influenced mainly by the time factor. Consequently, activities involving research, ideation, and evaluation are time-consuming, which compromises user research and the application of the principles of User-Centered Design. Therefore, the present research aims at investigating the research with users in consonance with the application of agile methodologies in the development of digital products. The literature review, allowed us to gain in depth knowledge about user-centered design, its principles, associated methodologies and its processes, and to relate UCD to agile methodologies. Through the interviews, it was also possible to understand the issues faced by UX professionals in the application of user-centered design practices in organizations, which generated inputs for the application of an online survey, which in turn enabled both the analysis of activities related to user research in the application of agile methodologies in the Brazilian market. This research reveals how UX professionals apply the activities that involve research with users along with agile methodologies according to the collected sample, the research findings also show what influences in the development of their products according to the presented organizational characteristics.

Recent advances in the field of Internet of Things (IoT) are placing its own vision, as a platform of interconnected services and devices, at the heart of the smart home concept. This consolidation promises a new wave of innovative products designed in the open, and in which the user takes center stage starting from the very first steps. Therefore, researchers as well as product designers in these increasingly related fields are now tasked with a more complex mission when investigating user behavior. In this thesis we consider rapid prototyping as the upcoming standard process for investigating user interactions in the future smart home. Although past research contributed with several self-contained solutions (built from scratch) to allow such investigations, no accounts were found tackling the problem from our perspective, in which the focus is on how to enable rapid prototyping in an existing proprietary smart home platform by using open standards, software and hardware. To answer this question, we conducted our research with participation of academic researchers and professional designers in the context of an academic and industrial partnership, in an ongoing smart home research project. We used an approach based on the design science research process in combination with the user centered design (UCD) and agile software development methodologies. During this thesis we performed an end to end design process starting from ideation to implementation and evaluation; an architectural blueprint was proposed and a working prototype of our visual smart home rapid prototyping environment (SHRPE) was implemented and tested. The obtained results demonstrate the feasibility of enabling visual rapid prototyping capabilities in an existing smart home platform, by using the system integration process to introduce available open standards, software and hardware tools into the platform. In addition, evaluation results of user testing confirmed that using UCD to iteratively capture user needs in such complex context is a solid approach.
