<div>Large datasets related to Indiana’s Education and Workforce development are used by various demographics such as stakeholders and decision makers in education and government, parents, teachers and employees of various companies to find trends and patterns in the data to better guide decision-making through statistical analysis. However, most of this data is scattered, textual and available in the form of excel sheets which makes it harder to look at the data from different perspectives, drill down and roll up the data and find trends and patterns in the data. Such data representation does not take into account the inherent characteristics of the user which can affect how well the user understands, perceives and interprets the data.</div><div>Information dashboards used to view and navigate between visualizations of different datasets, provide a coherent, central access to all data, and make it easy to view different aspects of the system. The purpose of this research is to create a new data visualization dashboard for visualizing education and workforce data and find which design principles are applicable while designing such a dashboard for the target demographic in the education and workforce domain. This study also aims at assessing how the introduction of such a data dashboard affects the work processes and decision making of stakeholders involved in education and workforce development in the state of Indiana.</div><div>User studies consisting of usability testing and semi-structured interviews with the stakeholders in education and workforce development in the state of Indiana is conducted to test the effectiveness of the dashboard. Finally, this research proposes how a regional map-based dashboard can be used as an effective method to design a data dashboard for education and workforce data for other states and other domains as well.</div>

<p>An application was developed to explore user interactions with the holographic sign language interpreters within HoloLens MR classrooms for Deaf and Hard of Hearing (DHH) students. The proposed system aims to enhance DHH students’ learning efficacy. Despite the ongoing advancement of assistive technology and the trend to adopt Mixed Reality applications into education, not much existing research provides user study or design guidelines for HoloLens development targeting the DHH community. The developed HoloLens application projects a holographic American Sign Language (ASL) avatar that signs the lecture while a speaking instructor is teaching. The usability test focused on avatar manipulation (move, rotate, and resize) and avatar framing (full-body and half-body displays) within the MR classroom. A mixed-method approach was used to analyze quantitative and qualitative data through test recordings, surveys, and interviews. The result shows user preferences toward viewing holographic signing avatars in the MR space and user acceptability toward such applications</p>

There are many possible tools to develop mobile applications with. Choosing a development tool is done by considering many different factors, and the choice is currently done, in many cases, arbitrarily. For this project, a decision model is designed to ease the process of choosing a development tool. A survey was conducted to examine how people using different smartphone platforms discover and download applications. 94 responses were collected, showing that approximately 50% of Android-users found mobile applications by using search engines or browsers. The corresponding number was approximately 30% for iOS-users. A usability test was conducted to discover the differences in user experience between Progressive Web Applications and native applications. 18 usability tests were conducted comparing the same product developed as a Progressive Web Application and a native application. A majority of the participants had a technical background. Both Android and iOS devices were included in the tests. The results indicated that end-users notice when an application is not natively developed. The effect on the user experience is combined with other technical differences and applied to the decision model. This model was designed to predict if a native application, a Progressive Web Application or a React Native application is the most favourable to develop for a specific scenario. The final model could, according to consultants at the stakeholder Slagkryssaren AB, with good accuracy predict when the different development tools should be used. The model could be used as a discussion tool in the first stages of the development process of an application. / Det finns många möjliga verktyg för att utveckla mobila applikationer. Valet av utvecklingsverktyg görs genom att överväga många olika faktorer, och görs idag i många fall högst godtyckligt. För det här projektet designades en beslutsmodell som förenklar processen av att välja ett utecklingsverktyg. En undersökning gjordes för att undersöka hur användare av olika smartphone- plattformar upptäcker och laddar ner applikationer. 94 svar samlades, svaren visade att ungefär 50% av Android-användare hittade mobila applikationer genom internetsökningar eller webbläsare. Denna siffran var ungefär 30% för iOS-användare. Ett användarbarhetstest utfördes för att finna skillnader i användarupplevelse mellan progressiva webbapplikationer och native-applikationer. En majoritet av deltagarna hade en teknisk bakgrund. Både Android- och iOS-enheter testades. Resultatet tydde på att slutanvändare la märke till när en applikation inte utvecklades som en native-applikation. Effekten på användarvänligheten, kombinerat med tekniska skillnader mellan verktygen, tillämpades på beslutsmodellen. Modellen designades för att förutse om en native-applikation, en progressiva webbapplikation eller en React Native- applikation är mest fördelaktig att utveckla i ett specifikt scenario. Den slutgiltiga modellen kunde, enligt konsulter på uppdragsgivaren Slagkryssaren AB, med god precision avgöra när de olika utvecklingsverktygen bör nyttjas. Modellens användning blev som ett diskussionsverktyg i de första stadierna av processen med att välja utvecklingsvektyg.

Workplace safety, particularly in manual handling tasks, is a critical concern that hasbeen increasingly addressed using advanced risk assessment tools. However, pre-senting the complex results of these assessments in an easily digestible format re-mains a challenge. This thesis focused on designing and developing a user-friendlyweb application to visualise risk assessment data effectively. Grounded in a robusttheoretical framework that combines user experience principles, and data visualisa-tion techniques. The study employed an iterative, user-centric design process to de-velop the web application. Multiple visualisation methods, such as pie charts for vis-ualising risk distribution, bar chart, and line chart for time-based analysis, were eval-uated for their effectiveness through usability testing. The application's primary con-tribution lies in its efficient data visualisation techniques, aimed at simplifying com-plex datasets into actionable insights. This work lays the groundwork enabling futuredevelopment by pinpointing areas for improvement like enhanced interactivity andaccessibility. / Belastningsergonomiska risker i arbetsmiljön, särskilt i uppgifter som involverarmanuell hantering, är en kritisk fråga som alltmer har adresserats med hjälp av avan-cerade riskhanteringsverktyg. Men att presentera de komplexa resultaten av dessabedömningar i ett lättillgängligt format kvarstår som en utmaning. Denna avhand-ling fokuserade på att designa och utveckla en användarvänlig webbapplikation föratt effektivt visualisera riskbedömningsdata. Studien bygger på en robust teoretiskram och kombinerar principer för användarupplevelse med datavisualiseringstekni-ker. Webbapplikationen har utvecklats med hjälp av en iterativ och användarcentre-rad designprocess. Flera visualiseringsmetoder, såsom cirkeldiagram för att visuali-sera riskfördelning, stapeldiagram och linjediagram för tidsbaserad analys, utvärde-rades för deras effektivitet genom användningstester och utvärderingsformulär. Ap-plikationens primära bidrag ligger i dess effektiva datavisualiseringstekniker, somsyftar till att förenkla komplex information till handlingsbara insikter. Detta arbetelägger grunden och möjliggör framtida utveckling genom att peka ut områden förförbättring, som förbättrad interaktivitet och tillgänglighet.

Sustainable consumption is used to describe consumer behaviors which aim to reduce environmental impact. One way of measuring sustainable consumption is by tracking products’ carbon footprint. Today however, there is limited research on how carbon footprint information is influencing consumers online, and few online tools which allow consumers to track carbon footprints for specific products before the point of purchase. The purpose of the thesis is to design a sustainability tool which contains product level carbon footprint information as well as to test and evaluate how the information affects sustainable consumption. Theory from the fields of Human Computer Interaction and Carbon Footprint research was used in a multi-method qualitative study. Expert interviews and qualitative usability tests were conducted during the thesis as means of collecting empirical data. The study concludes that carbon footprint information should be introduced in the search phase of the consumer journey. The information should then progressively become more detailed as the consumer approaches the point of purchase. The study found that displaying carbon footprint information affects sustainable consumption positively in the tested online environment. However, personal preference and cost constitute a large part of consumers' choices as well. The study extends the research on carbon footprints by including results from an online environment. Future research should be conducted using quantitative methods to validate the results of this study on larger samples. Other product categories should also be tested as a way of investigating if the same consumption patterns emerge across different product categories. / Hållbar konsumtion används för att beskriva konsumentbeteenden med syfte att minska miljöpåverkan. Ett sätt att mäta hållbar konsumtion är genom att spåra produkters koldioxidavtryck. I dag är dock forskningen kring hur koldioxidavtrycksinformation påverkar konsumenter online begränsad, och få verktyg tillåter konsumenter att spårasina koldioxidavtryck för specifika produkter innan köp. Syftet med studien är att designa ett hållbarhetsverktyg med information om koldioxidavtryck på produktnivå samt att testa och utvärdera hur informationen påverkar hållbar konsumtion. Teori från områdena Människa-datorinteraktion samt Koldioxidavtrycksforskning användes i en kvalitativ multimetodstudie. Expertintervjuer samt kvalitativa användbarhetstester genomfördes under studien som ett sätt att samla in empirisk data. Slutsatsen från studien visar att information om koldioxidavtryck bör introduceras i sökfasen av konsumentresan. Koldioxidinformationen bör sedan successivt bli mer detaljerad när konsumenten närmar sig köptillfället. Studien påvisar att koldioxidavtrycksinformation påverkar hållbar konsumtion positivt i den testade onlinemiljön. Dock påverkar även personlig preferens samt kostnad konsumenternasval. Studien utökar forskningen om koldioxidavtryck genom att inkludera resultat från en onlinemiljö. Framtida forskning bör utföras med hjälp av kvantitativa metoder för att validera resultaten av denna studie på en större urvalsgrupp. Även andra produktkategorier bör testas som ett sätt att undersöka om samma konsumtionsmönster uppstår över olika produktkategorier.
