I och med smarttelefonens intåg i våra liv har Augmented Reality (AR) kommit att bli en teknik i ropet. Många företag och utvecklare är intresserade av att undersöka dess potentiella användningsområden för just deras nisch. Men det är inte bara fantasin som sätter gränser - även hårdvaran. 2018 lanserades ARCore, en uppsättning utvecklingsverktyg för att bygga AR-appar för Android-smartmobiler. ARCore i sig har inte stöd för att bygga positionsbaserade appar, men i och med att smartmobiler och surfplattor är utrustade med GPS och kompass för att kunna avgöra sin position och orientering, syftar detta arbete till att utreda hur en platsbaserad AR-app för Android kan utvecklas, med målet att visa vägdata som AR-objekt. Projektet inleddes med en litteraturstudie för att undersöka teorierna bakom AR, positionsteknik och redan existerande platsbaserade AR-appar. Vidare genomfördes en fallstudie av att utveckla en AR-app för att visa utvald vägdata i stadsmiljö. Appen testades i stadsmiljö, där det upptäcktes att enhetens platsnoggrannhet var för dålig för att kunna placera och visa AR-objekt någorlunda verklighetstroget. Därefter gjordes en uppföljande litteraturstudie på området positionsteknik och platsnoggrannhet hos dagens mobila enheter för att undersöka vilka faktorer som påverkar enheters förmåga att bestämma sin position. Den uppföljande litteraturstudien visade att platsnoggrannheten framförallt påverkas av höga byggnader i närmiljön. / The introduction of the smartphone as we know it today, has made Augmented Reality (AR) a hot technology. Many companies and developers want to explore its potential uses within their area of interest. But not only does the imagination set the limits – the hardware does too. In 2018, ARCore was launched, a software development kit (SDK) for building AR apps for Android smartphones. ARCore itself does not provide support for building location-based apps, but since smartphones and tablets are equipped with a GPS and compass to determine their position, this project aims to explore how to develop a location-based AR app for Android, with the goal of visualizing road data as AR objects. The project started with a literature study to explore the theories behind AR, location technology and pre-existing location-based AR apps. This was followed by a case study of building an AR app to display selected road data in an urban environment. Tests with the app in an urban environment revealed that the location accuracy of the device was too poor to display AR objects in their correct position. To explore the major factors affecting a device’s capability to determine its position, a second literature study was conducted in the area of location technology in practice and accuracy of mobile devices. The second literature study showed that the location accuracy is mainly affected by tall buildings in the nearby area of usage.

The lack of digital and easily accessible information for home hemodialysis patients leads to a disinclination of using the provided manuals. This problem could potentially be solved with a user-friendly app, where all information and communication with the healthcare providers could take place. Hence, leading to them feeling better prepared to take charge of their own treatment. The purpose of this thesis is to provide a minimum viable product of a mobile application to facilitate treatment for home hemodialysis patients. The app was developed using the programming language SwiftUI. Information was collected from patients with home hemodialysis treatment through interviews conducted in their homes.  The mobile application enables patients to access the manual and failure identification codes through a search bar. It also provides digital checklists, dialysis protocol and symptom follow-up. The healthcare providers can then access the dialysis protocol and symptom follow-up through remote patient monitoring. A chat function allows patients to contact nurses. The mobile application fulfills the clients’ requests and with additional work it could be fully operational. / Bristen på digital och lättåtkomlig information för patienter med hemhemodialys leder till en ovilja att använda manualer och felkoder. En lösning på detta problem skulle kunna vara att utveckla en användarvänlig app som innehåller all nödvändig information, samt ett kommunikationsverktyg mellan patient och vårdpersonal. Syftet med detta examensarbete är att skapa en minsta gångbar produkt i form av en app för att underlätta behandlingen för patienter med hemhemodialys. Appen utvecklades med programmeringsspråket SwiftUI. Information hämtades från patienter genom utförda hemintervjuer.  Den mobila applikationen ger patienter åtkomst till manualen samt felkoderna genom en sökruta. Den innehåller även digitala checklistor, dialysprotokoll och symtomuppföljning. Vårdpersonal kan genom appen få tillgång till patienters dialysprotokoll och symtomuppföljning genom fjärrövervakning. Via chatten kan patienter kontakta sjukvårdspersonal. Applikationen uppfyller uppdragsgivarens önskemål om funktionaliteter. Om fortsatt arbete genomförs kan appen användas för att ge patienterna stöd i sin egenvård. / Nej

In this study, we investigate the cross-platform localization practices, emphasizing the synergy of Globalization, Internationalization, Localization, and Translation (GILT) within a multilingual context. Our methodology intertwines a literature review and interviews with localization professionals from diverse companies tackling crossplatform localizations. Our findings indicate a reliance on a range of digital tools yet highlight a need for further research. The study culminates in a classification of different types of challenges, and strategic recommendations to refine localization efforts across platforms.Key challenges include technical maturity differences between small and large companies, the necessity for standardization, and the complexity of managing multilingual content. Smaller firms often struggle with resource limitations and manual processes, prone to errors and inconsistencies. In contrast, larger organizations generally utilize sophisticated systems enabling efficient and scalable localizations.Recommendations emphasize early internationalization to ease future language additions, centralization to ensure consistency, and automation by integrating localization platforms with existing codebases. Continuous education is also crucial for all involved to enhance their understanding and capabilities.

With rapid technology growth and a rising disabled and aging population, mobile appaccessibility is vital. Stricter accessibility laws, especially in the public sector, highlight thisemphasis. However, despite this, the body of research focusing on software practitioners’perspectives, especially concerning cross-platform development, is lacking. In this qualitativecase study, six software practitioners at the Swedish Social Insurance Agency(Försäkringskassan) were interviewed about their experience during a migration betweenmobile development technologies, with a focus on enhancing mobile application accessibility.It explores their attitude to cross-platform development, their challenges with NativeScript, across-platform framework, and preferences for native technology. To further understand theiracceptance of native technology and their rejection of cross-platform technology in thiscontext, an extension of the Technology Acceptance Model (TAM2) was used. Respondents emphasized the legal and ethical obligations for accessibility in the publicsector, with evolving standards necessitating the selection of the most appropriate technologyfor the task. Prioritizing accessibility early on in public sector app development helps avoidadditional expenses later on. It's also possible that private sector apps may be required to shifttowards greater inclusivity in the future. The team successfully addressed previous accessibility issues using native technology, whichinfluenced the organization to migrate. Moreover, respondents believed that nativetechnology enhances professional image, especially as the industry favors it over unknowncross-platform frameworks. They perceived that cross-platform frameworks might lackthorough documentation and community support, making it more difficult to manage andimplement accessibility. Additionally, respondents are alarmed by the uncertain nature ofcross-platform technology, which can result in outdated frameworks and unworkablecodebases. It's crucial to consider the duration of the project, its accessibility needs, and theavailable support for implementing accessibility when deciding on mobile developmenttechnologies. These findings are valuable for various stakeholders, such as consultants,researchers and policy-makers.
