In today's use of digital services, we seamlessly perform lots of microinteractions. Mostly without noticing them. When analysing what's good or bad in interaction with digital services, it is common to focus only on the big functions and it is easy for the small, effective moments in a microinteraction to be overlooked. This study takes a closer look at the microinteractions found in digital applications. Specifically, user-triggered microinteractions. The purpose of the study is to gain a broader understanding of how these microinteractions are designed to affect the user experience and what emotions may arise during the encounter with a service by studying the hedonic and pragmatic qualities that can be found in service's microinteractions. In the study, we performed a systematic heuristic analysis of 60 microinteractions, selected from the Google Play Store's top list, where the microinteractions were assessed individually by the study's two authors using an analysis tool developed for the study. The results show that the most common hedonic qualities in design of microinteractions today meet the needs of autonomy, security and luxury. To fulfill these needs, the study shows a link between metaphorical design and a sense of security, minimalist design and luxury, as well as clear communication and autonomy. The three most common pragmatic qualities are consistency, recognition and metaphor, where the connections between design and quality are shown to be metaphorical design and consistency, as well as the location of the trigger and recognition.

This Masters's Thesis is devoted to first-user testing of web application of ALVAO, s.r.o. Theories of user experience or UX testing are summarized in theory. There are a theory of first-user testing, as well as the creation of global and "task" scenarios. In the practical part of the testing itself for the fictitious company is done. Most attention is paid to testing with test subjects. The resulting testing was evaluated and proposals for improving the application.

The goal of this text was to implement a mobile application for attendees of technology conferences. While creating the concept the user experience was highly emphasized and after doing the market research there were couple of surveys and discussions with potential users, that often attends those conferences. Resulting application got positive feedback about its UI/UX qualities and was marked as 8.3 out of 10 in these regards. Application was updated according to the concerns that users provided in feedback tests. In the end there were suggested additional improvements to the application, that would enhance user experience at the conference even more.

Den finansiella sektorn har kunnat ta del av stora fördelar med avancerade AI system som kan förutspå trender och ta egna beslut baserat på tidigare processer. Detta betyder att system som använder AI med 100-tals parametrar kan utföra mer arbete med mindre arbetstimmar än en människa. För att människan ska kunna lita på sådana tänkande maskiner måste människan ha möjligheten att förstå programmen så att hen kan kontrollera att systemet följer människors värderingar och behov. Kommunikationen mellan människa och system görs genom att maskinen förklarar varför den tog ett visst beslut även kallat “Explainable AI” (XAI). Studien som genomförts påvisar att XAI saknar tydliga riktlinjer hur dessa förklaringar bör designas för att skapa förståelse till de som arbetar med dessa kraftfulla system. Detta examensarbete fokuserar på att undersöka kreditchefers roll i banken, vad dom baserar sina beslut på och hur användarcentrerade förklaringar kan bidra till ökad förståelse av AIproducerade beslut av låneansökningar. För att uppnå detta resultat har UX-metoder används som sätter verkliga användare i fokus. Datainsamlingen bestod av kvalitativa intervjuer med kreditchefer på banker i Sverige som sedan analyserades och jämfördes med rådande forskning inom AI och XAI. Ett 30-tal domänspecifika parametrar identifierades som låg till grund för sex designade förklaringar där förståelsen utvärderades genom att jämföra förklaringarnas olika resultat från kreditcheferna. Fem rekommendationer presenteras om hur AI-system bör presentera förklaringar till kreditchefer på mindre banker i Sverige. / The financial sector has been able to enjoy great benefits with advanced AI systems that can predict trends and make their own decisions based on previous processes. This means that systems that use AI with hundreds of parameters can perform more work with fewer working hours than a human. In order for humans to be able to trust such thinking machines, humans must have the opportunity to understand the programs so that they can check that the system follows people's values and needs. The communication between humans and the system is done by the machine explaining why it made a certain decision also called "Explainable AI" (XAI). The study carried out shows that XAI lacks clear guidelines on how these explanations should be designed to create better understanding for those who work with these powerful systems. This thesis focuses on examining the role of credit managers in the bank, what they base their decisions on and how user-centered explanations can contribute to a greater understanding of AI-produced decisions of loan applications. To achieve this result, UX methods have been used that put real users in focus. The data collection consisted of qualitative interviews with credit managers at banks in Sweden, which were then analyzed and compared with current research in AI and XAI. About 30 domain-specific parameters were identified as the basis for six designed explanations where the understanding was evaluated by comparing the explanations' different results from the credit managers. Five recommendations are presented on how AI systems should present explanations to credit managers at smaller banks in Sweden.

Results of this work can be used for the development of applications with respect to user centered design.

Praktiska erfarenheter från fallföretaget och tidigare forskning visar på utmaningar i att kombinera processerna för agil systemutveckling och användarbaserad designutveckling. Användarbaserad designutveckling förespråkas av UX (User eXperience). Litteraturstudien visar på skillnader i syn på dokumentation, avsaknad av definierad process för gemensamma iterationer, problem med att bryta ner UX-arbete i små beståndsdelar samt hur rollen för UX kan eller ska arbeta tillsammans med utvecklingsteamet. Samarbete över funktionsgränser innebär ofta behov av informationsöverföring genom någon form av objekt eller artefakt. Studiens syfte är att bidra till den befintliga forskningen gällande interaktion mellan agila utvecklingsteam och UX-designers genom att undersöka båda parters perspektiv på hur gemensamt använda artefakter fungerar, för att effektivisera kommunikation, samarbete och informationsöverföring de två funktionerna emellan. Empirin är insamlad genom semistrukturerade kvalitativa intervjuer med produktägare, utvecklare, development managers och UX-designers/UX-specialister. Resultatet av empiri och analys visar att ingen av de funktionsöverskridande artefakterna som studien identifierat, stödjer informationsöverföring för båda funktionerna enligt kriterierna i Boundary Object Theory. Resultatet av den kontextualiserade jämförelsen i diskussionen visar att funktionernas metodologiska filosofi utgör ytterligare en möjlig barriär för effektivt samarbete funktionerna emellan. / Practical experience from the case company and previous research shows challenges in combining the processes for agile system development and user-based design development. User-based design development is advocated by UX (User eXperience). The literature study shows differences in their views on documentation, lack of a defined process for joint iterations, problems with breaking down UX work into small components and how the role for UX can or should work with the development team. Collaboration across functional boundaries often involves the need for information transfer through some form of object or artifact. The purpose of the study is to contribute to the existing research on the interaction between agile development teams and UX designers, by examining both parties' perspectives on how mutually used artifacts operates, to improve communication, collaboration and information transfer between the two functions. The empirical material was gathered through semi-structured qualitative interviews with product owners, developers, development managers and UX designers / UX specialists. The result of the empirical analysis show that none of the cross-functional artifacts identified in the study, that supports information transfer for both functions according to the criteria in Boundary Object Theory. The result of the contextualized comparison in the discussion shows that the methodological philosophy of the functions is another possible barrier to effective collaboration between the functions.

Unappealing websites are rejected quickly upon visiting them, while visitors spend more time on visually appealing websites before judging its reliability; but to what extent can visual appeal alone carry the success of a website, and is it so powerful that good usability can be sacrificed? This paper studies the respective importance of visual appeal and usability in e-commerce as factors, in order to determine which factor plays the bigger role in generating trust and credibility for an e-commerce site, as credibility perception is highly correlated with its visual complexity. The relation between these two factors and the likelihood to make a purchase is also discussed. Two prototypes for a fictional consumer electronics e-commerce website were created: one with good design and flawed usability, and another with flawed design and good usability. These prototypes were shown to students aged 20-25 and asked which one they found more trustworthy and which they would rather make a purchase from. With the correlation between trust and purchase intention being apparent, the design of an e-commerce website for consumer electronics should focus mainly on the visual appeal. Usability seems to have some value, however it does not seem to be of the same importance as the visual appeal of the site in regards to generating trust, and consequently customers. The prototypes were constructed in Adobe XD, demonstrated with video recordings, and sent out in a survey to 70 students.

Saab is a large swedish company providing a multitude of different products and services. This also means that Saab has to provide support and customer service for said products. Currently this is handled online in Support Portals, where customers and partners can access product information as well as an issue management system called SIRS. In the current situation the system is tailored for a desktop experience, and the workflow is therefore limited in terms of mobility. This project aims to allow the users to be more mobile by investigating the possibility of developing a mobile application for usage with SIRS. During the project a proof of concept of such an application has been developed. The implementation relies largely on using currently available api:s and when necessary porting some code from server to client side. By using various UX-related methods during the development of the application it is expected that the application is user friendly and fits the target audience. When looking at the result of the work, it is indeed possible to integrate a standalone mobile application with SIRS. The application also has usability which is comparable to the current system. However, some limitations were found that required rewriting the existing system to provide necessary data to client side applications like the one developed in this project. To conclude, the application is a proof of concept that shows what can be done without modifying the current system. Some of the major things that has to be modified before taking the application to production, such as stability concerns and testing, is also presented as results of the project.

I denna rapport beskrivs arbetet med att ta fram ett gränssnitt till en applikation för äldre. Målet med applikationen är att öka tryggheten och underlätta för äldre i vardagen, samt att minska social isolering. Frågeställningarna grundades dels på vilka funktioner som är relevanta och önskvärda i en sådan applikation, dels hur applikationen ska anpassas efter såväl låg teknikvana, som fysiska och kognitiva nedsättningar som är vanliga vid hög ålder. Arbetet inleddes med litteraturstudier om målgruppen, dess behov och svårigheter. Relaterade arbeten och liknande produkter granskades. Dessutom studerades olika designmetoder och -verktyg som ansågs vara relevanta för projektet. Arbetsprocessen bestod av iterativa cyklar där designval och funktioner diskuterades och utvecklades med hjälp av olika designverktyg. Dessa utvärderades sedan genom användartester. Resultatet från testerna analyserades och bidrog till ändringar och vidarutvecklingar i nästa cykel. Resultatet består av en interaktiv prototyp som grundar sig i teori och de upptäckter som gjorts under arbetets gång. Rapporten avslutas med en diskussion om huruvida resultatet uppfyllde målen och vad som fungerat bra och mindre bra i arbetsprocessen. Dessutom diskuteras etiska aspekter med arbetet och möjlig vidareutveckling.
