Video editing is a process where multiple roles are required to collaborate. Despite this, the design of video editing software does not easily support collaboration. Hence, this study investigates how the video editing workflow can be improved by designing a user interface that supports collaboration. This is achieved with focus on simultaneous work performed in a remote workspace. Firstly, a design workshop was conducted with professional video editors. Secondly, user interface mockups were created. Lastly, the mockups were evaluated in a mockup test and subsequently updated based on the feedback. The study proposes five design concepts that collectively aim to support collaboration through workspace awareness by focusing on enhancing communication to make the workflow more time efficient. The evaluation of the design concepts indicates their potential to facilitate the collaborators collective work and communication. Therefore, the results suggest that the workflow has the possibility to be improved by including collaborative features in video editing software. / Videoredigering är en process där flera roller behöver samarbeta. Trots detta stöder designen av videoredigeringsprogram inte samarbete. Därför undersöker denna studie hur arbetsflödet för videoredigering kan förbättras genom att utforma ett användargränssnitt som stöder samarbete. Detta uppnås med fokus på arbete som utförs samtidigt på distans. Först genomfördes en designworkshop med professionella videoredigerare. Sedan skapades mockups för användargränssnittet. Slutligen utvärderades mockuperna i en mockup-testning och uppdaterades därefter baserat på feedbacken. Studien föreslår fem designkoncept som tillsammans syftar till att stödja samarbete genom arbetsplatsmedvetenhet genom att fokusera på att förbättra kommunikationen för att göra arbetsflödet mer tidseffektivt. Utvärderingen av designkoncepten indikerar deras potential att underlätta medarbetarnas kollektiva arbete och kommunikation. Därför tyder resultaten på att arbetsflödet har möjlighet att förbättras genom att inkludera samarbetsfunktioner i videoredigeringsprogram.

With today’s exploding amount of websites and applications, a design has to meet the requirements of its users and be easy to use in order for a software product to stand out. User Experience design is a method, which has been developed to design products with a focus on the user. This thesis examines how User Experience design can be applied to the creation of a wiki in order to ease the acquisition of information. The research was done through a literature study and a case study, where a wiki about courses at KTH was designed and tested. Two versions of a prototype were created, based on feedback which was collected from potential users. A thematic analysis was done on the data and the selected themes were used to improve the product. The result was an overall positive response towards the prototype in the case study, which led to a conclusion that User Experience design can lead to an improvement of how wikis are created. The work can be continued by implementing the prototype or creating more wikis for a broader support of the conclusion. / Med dagens exploderande mängd websidor och applikationer krävs en design som möter användarnas krav och är lättanvänd för att en mjukvaruprodukt ska stå ut. Användarupplevelse design är en metod som tagits fram för att designa produkter med användaren i fokus. Detta arbete undersöker hur användarupplevelse design kan appliceras på skapandet av en wiki för att förenkla inhämtningen av information. Undersökningen gjordes med hjälp av en litteraturstudie och en fallstudie där en wiki kring kurser som ges på KTH designades och testades. Två versioner av en prototyp skapades utifrån feedback som samlats från potentiella användare. En tematisk analys utfördes på datan och de uttagna temana användes för att förbättra produkten. Resultatet var ett generellt positivt bemötande mot prototypen i fallstudien, vilket ledde till en slutsats att användarupplevelse design kan leda till en förbättring av hur wikis byggs. Arbetet kan fortsättas genom att implementera prototypen eller skapa fler wikis för ett bredare underlag.

Lack of trust is argued to be one of the key reasons behind buyers’ reluctance to purchase online. In mobile commerce (m-commerce), gaining initial trust upon the first visit from prospective consumers highly depends on the design of the website. However, the number of qualitative empirical studies investigating what and how website characteristics affect initial trust in an unfamiliar m-commerce website remains limited. The aim of this thesis was thus to gain a deeper understanding of the influence of website characteristics on initial consumer trust in a m-commerce website, to provide insights for designers. An exploratory case study of the mobile version of an e-vendor’s website was conducted and qualitatively examined through Think-Aloud sessions and semi-structured interviews. By thematically analyzing the data, the following website characteristics were identified as influencing initial trust in an unknown m-commerce website: purposeful and clear visual design, internal design consistency, mobile adaptation and reading experience, content quality, similarity and expectations, social proof and external validation. Based on the insights, the study further provides recommendations to practitioners on how to design trustworthy m-commerce websites, both as support in the design pro-cess and for evaluation purposes. / Brist på förtroende anses vara en av de viktigaste orsakerna till att köpare tvekar att handla online. Att få initialt förtroende vid potentiella konsumenters första besök inom mobil handel (m-commerce) beror mycket på webbplatsens design. Antalet kvalitativa empiriska studier som undersöker vad och hur webbplatsens egenskaper påverkar initialt förtroende för en okänd m-handelswebbplats är dock fortfarande begränsat. Syftet med denna avhandling var således att få en djupare förståelse för hur webbplatsens egenskaper påverkar konsumenternas initiala för-troende för en mobil handelswebbplats, för att ge insikter till designers. En undersökande fall-studie av mobilversionen av en e-handlares webbplats genomfördes och undersöktes kvalitativt genom Think-Aloud-sessioner och halvstrukturerade intervjuer. Genom att tematiskt analysera den insamlade datan identifierades följande webbplatsegenskaper att påverka initialt förtroende för en okänd mobil handelswebbplats: målmedveten och tydlig visuell design, internt konsekvent design, mobilanpassning och läsupplevelse, innehållskvalitet, likhet och förväntningar, socialt bevis och extern validering. Baserat på insikterna ger studien rekommendationer till designers om hur man kan utforma pålitliga m-handelswebbplatser, både som stöd i designprocessen och för utvärdering.

Many different autonomously driving mobile robots are used for industrial transports of materials or  oods in the context of internal logistic processes because of different use cases. The problem for the users that need to monitor the robots is that each manufacturer provides its own graphical user interface (GUI) wi th different operating modes and visual designs, which requires different trainings and constant swi tching between software. Therefore, this paper shows the design and development process of a graphical user interface in the form of a web application for the monitoring process of a fleet of automated guided vehicles from different manufacturers and answers the following question: "What are the main criteria when designing a graphical user interface with high usability for the monitoring process of manufacturer-independent automa ted guided vehicle f leets?” To answer the question, existing graphical user interfaces from different manufacturers were analyzed and interviews with developers and end-users of the GUIs were conducted. Requirements were then derived, on whose basis sketching, wireframing and high-fidelity prototyping have been performed. Usability testing and a heuristic evaluation were chosen to improve the application and its usability continually. As a result, the following six main criteria could be derived that summarize the most essential points to consider when designing such a GUI: administrabi lity, adaptiveness, observability, analyzability, robot and job awareness, and intervention. / Många olika autonomt körande mobila robotar används för industriell transport av material eller varor i samband med interna logistiska processer till följd av olika användningsfall. Problemet för de användare som behöver övervaka robotarna är att varje tillverkare tillhandahåller sitt eget grafiska användargränssnitt (GUI) med olika driftsätt och visuella utformningar, vilket kräver olika  utbildningar och ständig växling mellan mjukvara. Denna uppsats visar därför design- och utvecklingsprocessen för ett grafiskt användargränssnitt i form av en webbapplikation för övervakningsprocessen för en samling av automatiserade guidade fordon från olika tillverkare, och svarar på följande fråga: "Vilka är de viktigaste kriterierna vid utformningen av ett grafiskt användargränssnitt med hög användbarhet för övervakningsprocessen av automatiserade guidade  fordonsamlingar, oboeroande av tillverkare?” För att svara på frågan analyserades befintliga grafiska användargränssnitt från olika tillverkare, samt intervjuer med utvecklare och slutanvändare av GUI:erna utfördes. Krav härleddes sedan, baserat på vilka skisser, wireframing och hifi -prototyper som har utförts. Användbarhetstest och en heuristisk utvärdering valdes för att kontinuerligt förbättra applikationen och dess användbarhet. Som ett resultat kan följande sex huvudkriterier härledas, de sammanfattar de viktigaste punkterna att tänka på när man utformar ett sådant GUI: förmåga att administrera, anpassningsförmåga, observerbarhet, analyserbarhet, robot- och jobbmedvetenhet och intervention.

The objectives and goals of this study is to analyze different styles of viewing information on mobile platforms and to find out what each different view brings to the table by creating and testing them with varied users. The study takes into account List View, Scroll View, and Grid View and compares them while viewing three different data formats. For this study, plain text, tabulated text, and interactive text will be analyzed. Smart mobile devices are the most used platform to view data in today's information rich world according to a survey conducted by Forrester Research. When designing for them, a lot must be considered but not knowing what is best suited for each application can be daunting for developers and designers, especially in the user experience context. This study aims to explore each mobile interface and give a better understanding about the different user interface designs features. Information visualization on cross-media information spaces and platforms is an important part of how information is disseminated today. Considering nowadays people get their information through multiple different media platforms like tablets, mobile phones, and web browsers, how to visualize data across all these platforms is a study to focus on in itself. The study showed that users performed better with certain views paired with different data types over others. Certain features of each view helped users understand the data types better over others while others improved users speed in reading data. Users showed certain preferences when interacting with each view on mobile devices when viewing cross media information which is mentioned in the study. / Målet för den här studien är att analysera olika sätt att visa information på mobila enheter och jämföra dessa genom att testa med olika användare. Studien undersöker de olika vyerna List View, Scroll View och Grid View och jämför dem med tre olika dataformat: vanlig text, tabellerad text och interaktiv text. Smarta mobila enheter är den mest använda plattformen för att synliggöra i dagens informationsrika samhälle enligt en undersökning av Forrester Research. När man utformar designlösningar för smarta mobila enheter är det mycket man behöver ta hänsyn till. Att inte veta vad som är bäst för varje applikation kan vara en svår uppgift för utvecklare och designers, särskilt ur användarperspektiv. Den här studiens syfte är att utforska varje mobilt gränssnitt och ge en bättre förståelse för de olika designlösningarna. Att visualisera information på olika mediers informationsytor och plattformar är en viktig del av hur information sprids idag.Om man tar i beaktan att människor numera får information via flertalet medieplattformar som tex läsplattor, mobiltelefoner, och webbläsare så inser man att visualisering av data på alla dessa medieplattformar är en studie i sig. Studien visade att användare lyckades bättre med vissa vyer och datatyper i kombination jämfört med andra. Specifika funktioner i varje vy hjälpte användare att förstå vissa datatyper bättre än andra, medan andra förbättrade användarnas snabbhet att läsa data. Användare tycktes föredra att interagera med vyer på mobila enheter när de tittade på information på olika medieplattformar, vilket nämns i studien.

As increasingly large displays are integrated into personal workspaces, mouse-based interaction becomes more problematic. Users must repeatedly "clutch" the mouse for long distance movements [61]. The visibility of the cursor is also problematic in large screens, since the percentage of the screen space that the cursor takes from the whole display gets smaller. We test multi-scale approaches to mouse interaction that utilize dynamic speed and size techniques to grow the cursor larger and faster for long movements. Using Fitts' Law methods, we experimentally compare different implementations to optimize the mouse design for large displays and to test how they scale to large displays. We also compare them to techniques that integrate absolute pointing with head tracking. Results indicate that with some implementation level modifications the mouse device can scale well up to even a 100 megapixel display with lower mean movement times as compared to integrating absolute pointing techniques to mouse input while maintaining fast performance of the typical mouse configuration on small screens for short distance movements. Designs that have multiple acceleration levels and 4x maximum acceleration reduced average number of clutching to less than one per task in a 100 megapixel display. Dynamic size cursors statistically improve pointing performance. Results also indicated that dynamic speed transitions should be as smooth as possible without steps of more than 2x increase in speed. / Master of Science

<p dir="ltr">Managing a forest presents many challenges for tree farmers, especially when relying on traditional manual methods. Previous research highlights the wide range of tasks involved in forest management, from planting and nurturing trees to harvesting and selling timber. These conventional approaches often result in inefficiencies and unexpected difficulties at various stages. However, advances in technology, specifically through the use of LiDAR-based reconstruction and differential geometry, have made it feasible to accurately measure tree sizes and identify species with a single capture.</p><p dir="ltr">To help tree farmers overcome these challenges, this thesis proposes the development of a cross-platform solution named WoodWiz. WoodWiz comprises two synergistic components: a mobile application for real-time, on-site tree measurements, and a web-based platform for comprehensive forest management. The measurement feature in mobile app streamlines the data collection process, reducing time and labor, while MyForest offers a detailed view of the forest's status, facilitating efficient management and planning. Additionally, WoodWiz includes a Library feature, providing a repository of forestry resources and best practices, and a community platform to foster collaboration and knowledge sharing among forestry professionals. This integrated system simplifies the wide range of tasks involved in forest management—from planting and nurturing to harvesting and selling timber—thereby reducing inefficiencies and addressing the unexpected difficulties typically associated with traditional methods.</p><p dir="ltr">The development of WoodWiz involved extensive research, design, and evaluation, culminating in a robust tool that not only streamlines forest management tasks but also provides tree farmers with actionable insights for decision-making. By automating critical measurements and facilitating data access, WoodWiz improves the accuracy of forest inventory and health assessments, leading to more informed and strategic management practices. The potential impacts of this solution on the forestry industry include increased productivity, improved sustainability of forest resources, and enhanced profitability for tree farmers. This thesis details the iterative process of WoodWiz's development, highlights its key features, and evaluates its effectiveness in transforming forest management practices.</p>

This study seeks to investigate the subtle impact that dynamic design elements in web interfaces have on users, particularly on users' decision-making and engagement. In contrast to most current research efforts, which predominantly address mobile applications, the current study aims to direct the focus on web-based environments to reveal special behavioral responses evoked by dynamic design features. The study adopts a comprehensive mixed-methods approach that encompasses qualitative and quantitative data collection techniques. This includes A/B testing on the prototypes of web interfaces, which provides the base for measuring engagement objectively from users. A very salient point here is that animations increase user retention by 30%, which shows that well-applied dynamic elements can advance the stickiness and interaction users would have with a digital platform. On the other hand, the thesis also mentions the risks related to such design elements, like the ability to cause cognitive overload and distraction in case of non-judicious use of these elements. Through the account of user behavioral analysis in response to various implementations, the research provides useful insights to web designers and developers about how to use animations and transitions judiciously for navigational intuitiveness and responsiveness without hampering web interface usability. The present research also adds to theories for UX and user interface design (UID) by promoting the balanced integration of dynamic design elements. What was brought to the forefront was that research to understand the specific impacts of these elements can lead to more effective digital environments, tailored to foster user engagement that could support efficient processes of decision making. This thesis not only fills the academic gap related to digital interaction but also provides a practical guideline for the improvement of web interface design given user behavior and technology.

<body>Users require flexibility when interacting with information systems to contend with changing business processes and to support diverse workflow. Model-based user interface design can accommodate flexible business processes by integrating workflow modelling with other modelling approaches. We present a workflow model, the progression model, to help in developing systems that support flexible business processes. <p> The progression model tracks a users interaction with an application as a set of data elements we refer to as a workflow transaction. The steps a user takes to create a workflow transaction and the state of the workflow transaction at each step is made explicit. By making the workflow status and workflow transaction state explicit, the user can change the order of the steps in a process, manage multiple workflow transactions, keep track of data as it is accumulated, and so on. The intent is to provide the user with a mechanism to deal with partial information, interrupted and concurrent workflow transaction entry, and the processing of multiple workflow transactions. <p> This thesis describes the progression model, an XML-compliant notation to specify the progression model, and a prototype system. </body>
