Ever wondered how trains arrive and depart on time? Traffic Control systems are there to help control the traffic flow, with many operators monitoring and taking actions when necessary. Operators of the traffic control systems use a keyboard and a mouse to interact. Current user interface and work setup consist of many usability issues that can be improved in order to increase operator’s efficiency and productivity in controlling the traffic. Interviewing users of the system and researching on related topics led to a newly proposed design in interaction, user interface as well as some suggestions for increasing productivity. Gesture-based interaction is introduced and simulated for traffic control systems that tend to improve the operation. Various gestures are designed such as panning, zooming and hovering the map using Leap Motion controller which enables intuitive interaction. These gestures aim to solve identified usability issues discovered during the interview with the user. The project aims to answer the following question: Can gesture-based interaction solve usability issues and establish the intuitive use of the CTC system? Performing exploratory research on this topic involved designing, implementing and testing hand gestures with users. From an ergonomic perspective, body posture and hand position of the operator is examined and suggested to use sit-to-stand workstations in order to reduce pain and discomfort while working. Gesture-based interaction eliminates finding mouse cursor on large screens, it enables fast request of detailed information and also it provides a better overview of the map surroundings. Laboratory tests confirm that gesture-based interaction brings more natural and intuitive use of traffic control systems. There is a big potential for gesture-based interaction to increase usability and bring efficient controlling for operators. It would reduce delays of the train and maintain safe traffic flow. / Har du någonsin undrat hur tåg anländer och avgaå i tid? Trafikledningssystem (CTC-system) hjälper till att kontrollera trafikflöet där operatörer övervakar och vidtar åtgärder vid behov. Operatörer av ett trafikledningssystem använder idag ett tangentbord och en mus för att interagera. Det nuvarande användargränssnittet och arbetsinstallationen består av många användbarhetsproblem som kan förbättras för att öka operatörens effektivitet och produktivitet för att kontrollera trafiken. Intervjuer med användare av systemet samt forskning om ämnet ledde till ett nytt föreslag av interaktion, utformning av användargränssnitt samt några förslag för att öka produktiviteten. Den gestbaserade interaktionen som infördes och simulerades för trafikkontrollsystemet tenderar att förbättra funktionen. Olika gester utformades som möjliggör för användaren att panorera, zooma och sväva över kartan. Gesterna implementerades med hjälp av Leap Motion Controller som möjliggör intuitiv interaktion. Dessa gester syftar till att lösa identifierade användbarhetsproblem som upptäcks under intervjuerna med användarna. Syftet med detta arbete var att svara på följande forskningsfråga: Kan gestbaserad interaktion lösa användbarhetsproblem och etablera intuitiv användning av CTC-systemet? Den explorativa forskning som utfördes i detta arbete inkluderade att utforma, genomföra och testa gester med användare. Kroppshållning och handposition för operatorerna undersöktes ur ett ergonomiskt perspektiv och studien föreslår att använda sitt-till-stå arbetsstationer för att minska smärta och obehag under arbetet. Gestbaserad interaktion eliminerar problemet att hitta muspekaren på stora skärmar, vilket gör det enkelt att snabbt hitta detaljerad information och ger även en bättre överblick över kartans omgivning. Laboratorietester bekräftar att gestbaserad interaktion ger mer naturlig och intuitiv användning av trafikledningssystemet. Det finns en stor potential för gestbaserad interaktion för att öka användbarheten och ge en effektiv kontroll för operatörerna. Det skulle minska förseningarna av tåget och upprätthålla ett säkert trafikflöde.

In today's digital age, efficient field operations are crucial for success across various industries. However, usability challenges are often overlooked in favour of functionality, hindering seamless task execution in the field. Evado, a company specialising in software solutions for field workers, offers the Evado Mobile Flow application to help streamline their operations. Yet, as demands evolve and complexities increase, usability shortcomings become increasingly apparent. Therefore, this master's thesis aims to optimise field operations by redesigning Evado Mobile Flow to enhance usability and efficiency. Critical usability challenges within the current interface are identified, such as usage difficulties for new users, followed by a comprehensive redesign process using the double diamond design approach. The methodology encompasses discovery, definition, development, and delivery phases, ensuring an effective outcome. The project started with the discovery and define phases, focusing on understanding user needs and interface limitations. Various techniques, including literature review, benchmarking, navigation flowchart, interviews, observations, hierarchical task analysis, and personas, provided valuable insights into the interface and user understanding, which helped to understand the existing problems. Next up was the development and delivery phase, which employed ideation methods such as braindrawing and scampering to generate a broad range of improvements and ideas. These were evaluated through a Pugh matrix and refined through iterative prototyping. The winning design proposal then underwent usability tests, focusing on task completion rates, clicks, user satisfaction, and potential improvements. The initial round of testing on the first prototype prompted a redesign, addressing newly identified usability challenges and introducing new functionalities aligned with evolving user needs. After a redesign, the final design underwent a second usability test and a system usability scale, yielding a usability score of 88.8 and recommendations for future iterations. Recommendations for future work and iterations include exploring the redesigned interface's long-term impacts on field operations and opportunities for further enhancement. This thesis emphasises the importance of user-centred design in developing effective digital solutions and provides a framework for similar endeavours in mobile interface design. / I dagens digitala ålder är effektiva fältoperationer avgörande när det gäller framgång inom olika industrier. Trots det förbises användbarhetsutmaningar ofta till förmån för funktionalitet, vilket förhindrar effektivt utförande av uppgifter i fältet. Evado, ett företag specialiserat på programvarulösningar för fältarbetare, erbjuder applikationen Evado Mobile Flow för att hjälpa till att effektivisera denna typ av verksamhet. Ändå, i takt med att kraven utvecklas och komplexiteten ökar, blir bristerna i applikationens användbarhet alltmer uppenbara. Därför syftar detta examensarbete till att optimera fältoperationer genom att omforma Evado Mobile Flow för att förbättra användbarheten och effektiviteten. Kritiska användbarhetsutmaningar inom den nuvarande gränssnittet har identifierats, som svårigheter att använda gränssnittet som en ny användare, och följts upp med hjälp av en omfattande designprocess. Vilket har skett med hjälp av double diamond design processen. Metoden omfattar de olika faserna av upptäck, definiera, utveckla och leverera, vilket säkerställer ett effektivt resultat. Projektet inleddes med faserna upptäck och definiera, vilka fokuserade på att förstå användarnas behov och gränssnittets begränsningar. Olika tekniker, inklusive litteraturundersökning, benchmarking, navigationsflödesschema, intervjuer, observationer, hierarkisk uppgiftsanalys och personas, gav värdefulla insikter i gränssnitt- och användarförståelse, vilket hjälpte till att förstå de befintliga problemen. Nästa steg var utvecklings- och leveransfasen, som använde idégenererings metoder som braindrawing och scamper för att generera ett brett utbud av förbättringar och idéer. Dessa utvärderades genom en Pugh-matris och förfinades genom iterativa prototyper. Det vinnande designförslaget genomgick sedan användbarhetstester, med fokus på godkänt genomförande, klick, användarnöjdhet och potentiella förbättringar. Den initiala omgången av testning som skedde på den första prototypen ledde till en iteration i designen, vilket adresserade nya identifierade användbarhets-utmaningar och introducerade nya potentiella funktioner som kan anpassas till användarnas behov. Efter denna iteration genomgick den slutliga designen ett andra användbarhetstest samt metoden system usability scale, vilket resulterade i ett betyg på användbarheten, på 88.8 poäng och nya rekommendationer för framtida iterationer. Rekommendationer för framtida arbete och iteration på denna applikation kan vara att utforska det omformade gränssnittets långsiktiga påverkan på fältoperationer och möjligheter till ytterligare förbättringar. Detta examensarbete betonar även på vikten av användarcentrerad design i utvecklingen av effektiva digitala lösningar och tillhandahåller därmed en ram för liknande utveckling inom mobilgränssnittsdesign.

The use of interactive e-learning tutorials is an effective form of teaching and learning. It is therefore important that attention is paid to their usability. This research relates to the evaluation of a CD-based e-learning tutorial for learning Business English, with the aims of investigating its usability and identifying problems. Particular attention is paid to aspects that hinder the learner from achieving the learning objectives. The study uses two usability evaluation methods (UEMs), namely controlled usability testing in an HCI laboratory and a user questionnaire survey. The main aim of the study is to compare the findings and determine the impact of using two methods in combination. The first outcome of the research was a synthesized framework of evaluation criteria that was applied in the two UEMs. Secondly, findings of the evaluations indicated that two UEMs identified similar problems, thus confirming their reliability in usability evaluation. Another finding was instances where one method produced results not obtained by the other, which shows the complementary value of two different UEMs. A third benefit of the study was that it identified usability problems in the target system. / Information Systems / MA (Information Systems)

隨著數位相機、智慧型手機等影像記錄產品的普及，人們可以隨時隨地按下快門，使得個人相片的數量不斷的增長。倘若照片中缺少了註釋，進行搜尋檢索大量的個人照片是困難的。雖然如此，人們卻會因為繁瑣累人的照片註釋工作而缺乏意願。 本研究藉由Kuo所發展出的PARIS (Personal Archiving and Retrieving Image System)作為來源系統架構，其系統解決了大部分個人數位影像語義標註的困難，也利用半自動註記方法減少使用者註釋負擔。但由於過去缺乏行動載具，PARIS並未開發一個現代化的行動註釋系統，來協助一般使用者進行個人影像註釋。 為了解決此問題，本研究利用使用性工程進行系統的建構，以設計及開發出一套現代化的行動影像註釋系統iPARIS (Integrated Personal Archiving and Retrieving Image System)。iPARIS擴展了PARIS設計出符合行動載具的後設資料結構與本體，包含將PARIS所定義的DDDC後設資料標準擴充為得以群眾註記之社群媒體地理標籤的iDDDC (Integrated Dozen Dimensional Digital Content)，以及在既有的STO (Spatial and Temporal Based Ontology)的空間架構中加入更具彈性的地理標籤關聯方法GRO (Geotag Related Ontology)。iPARIS並利用工作流程設計、介面線稿設計、視覺設計、系統實作、使用者參與設計等步驟來設計及開發系統，再以迭代設計方法不斷地改善系統的使用者介面及使用者體驗。iPARIS在建置完成後利用參與啟發式評估量表、手勢次數、操作時間、操作路徑、錯誤次數進行使用性測試，而其測試結果也達預期的使用性目標。更進一步，透過分析使用者操作系統的實際行為來找出系統存在的使用性問題，並提出未來系統的改進方式。 透過完整的規劃與適切的設計系統介面，讓使用者在拍照、註釋、組織及管理照片都可以在行動應用程式上完成，並使此系統能滿足具有效率、具學習性、具記憶性、低錯誤率及高滿意度等Nielsen所提出的使用性標準，以降低個人影像註釋時的負擔，並增加使用者註釋個人照片的意願，以應付日益增長地個人數位影像資料的管理需求。 / With the widespread use of photograph recording products, such as digital camera and smartphone, people take photographs easily so that the number of personal photographs increases unceasingly. If photographs are lacking of annotation, searching and retrieving the large number of personal photographs become difficult. However, people are usually reluctant to the cumbersome and exhausted annotation work. In 2004, Kuo et al. developed PARIS (Personal Archiving and Retrieving Image System) to solve these problems. Based on MPEG-7, PARIS resolved most difficulties of personal digital image semantic annotation and lightened users’ annotation burdens by semi-automatic annotation methods. However, because of the lack of mobile device at that time, PARIS did not develop a modern mobile annotation system to help ordinary people annotate personal photographs. Therefore, this thesis builds a system with usability engineering as well as designs and develops a modern mobile image annotation system iPARIS (Integrated Personal Archiving and Retrieving Image System). iPARIS expands PARIS architecture to add the support for mobile. It expands PARIS DDDC metadata standard to iDDDC (Integrated Dozen Dimensional Digital Content) which is a crowdsourcing annotation enabled by third party social networking services, and provides STO’s spatial ontology a more flexible geo-information description methodology GRO (Geotag Related Ontology). iPARIS also takes the steps of workflow design, wireframe design, visual design, system implementation, participatory design to build the system; moreover, it keeps improving the user interface and user experience by iterative design. After implementing iPARIS, we conduct usability testing including participatory heuristic evaluation, gesture times, operation time, gesture path, error times, and interview. The test results reach the expected usability goals. Furthermore, the thesis finds some usability problems by analyzing users’ behaviors when they are using the application and brings future improvement for the system. By integral planning and appropriate interface design, this system lets user take, annotate, organize, and mange personal photos in a mobile application. We hope that iPARIS can meet the usability index to lighten the burdens of personal photograph annotation, arousing users’ desire to annotate personal photographs, and meet the growing needs for the management of personal digital photograph information.

A prototype of a CMS was created based on literature studies about UX and CMS. The prototype of the user friendly CMS was then tested through user tests and interviews with key users. After input from the key users the prototype was changed until the users were satisfied with it.

This master thesis investigates how an Agile User Centered approach can be used when designing and implementing the frontend for a web-based on-demand video streaming platform. Agile and User Experience (UX) are currently two very popular concepts that are frequently discussed in the software development community. Recently there have been a lot of discussions about how to combine Agile development methodologies and UX activities, and it has proven to be a difficult task in practice. This Master Thesis aims at solving this issue by researching methodologies that take both the Agile aspect as well as UX in consideration. Dual-track Scrum, an Agile/User Centered methodology considering UX, was used as development methodology and throughout the development process it was investigated how this methodology, as well as adding UX activities, affected the UX of the streaming platform. The conclusion from this thesis is that even though the combination of Agile and User Centered processes is difficult, it can be achieved with good results. The thesis presents guidelines for how to successfully combine the two processes as well as what the most important UX activities are and how they can be used in an Agile development project. The thesis also concludes that using a frontend framework, development tools and HTML5 video is very useful for developing the frontend for the streaming platform.
