Root cause analysis (RCA) is a process in Scania carried out to understand the root cause of vehicle breakdowns. It is commonly done by studying vehicle warranty claims and failure reports, identifying patterns that are correlated to the breakdowns, and then analyzing the root cause based on those findings. Vehicle usage is believed to be one of the factors that may contribute towards the breakdowns, but the data on vehicle usage is not commonly utilized in RCA. This thesis investigates a way to help RCA process by introducing a dataset of vehicle usage based on position data gathered in project FUMA (Fleet telematics big data analytics for vehicle Usage Modeling and Analysis). A user-centered design process of a visualization tool which presents FUMA data for people working in RCA process was carried out. Interviews were conducted to gain insights about the RCA process and generate design ideas. PACT framework was used to organize the ideas, and Use Cases were developed to project a conceptual scenario. A low fidelity prototype was developed as design artifact for the visualization, and a formative test was done to validate the design and gather feedback for future prototyping iterations. In each design phase, more insights about how visualization of vehicle usage should be used in RCA were obtained. Based on this study, the prototype design showed a promising start in visualizing vehicle usage for RCA purpose. Improvement on data presentation, however, still needs to be addressed to reach the level of practicality required in RCA. / Root cause analysis (RCA) är en process på Scania som används för att förstå rotorsaken till fordons behov av reparation.Oftast studeras fordonets försäkringsrapporter och felrapporter, för att identifiera och analysera mönster som motsvarar de olika behoven för reparation. Fordonsanvändningen tros vara en av de faktorer som bidrar till reparationsbehoven, men data angående detta används sällan i RCA. Denna rapport undersöker hur RCA-processen kan dra nytta av positionsdata som samlats in i projekt FUMA (Fleet telematics big data analytics for vehicle Usage Modeling and Analysis). En användarcentrerad designmetodik har använts för att ta fram ett visualiseringsverktyg som presenterar FUMA-data för personer som deltar i RCA-processen. Intervjuer har genomförts för att samla insikter om RCA-processen och för att generera designidéer. PACT-ramverket användes sedan för att organisera idéerna, och användningssituationer togs fram för att skapa ett konceptuellt scenario. En low-fidelity prototyp togs fraför personer som deltar i RCA-processenm som en designartefakt för visualiseringen och ett utvecklande test genomfördes för att validera designen och samla in feedback för framtida iterationer av prototyping. Under varje design-fas, samlades mer insikter om hur visualiseringen av fordonsanvändning skulle kunna användas för RCA in. Baserat på detta, visade design-prototypen en lovande start för visualisering av fordonsanvändning i RCA. Förbättringar på hur data presenteras måste dock genomföras, så att rätt genomförbarhet för RCA uppnås.

Vid rökdykning i stora byggnader har rökdykare problem med desorientering, stora avstånd och lokalisering av branden. Detta arbete utforskar användbarheten och rollen av en brandrobot, FUMO, vid rökdykning i industrilokaler och underjordiska parkeringshus. Genom att intervjua brandmän med erfarenhet av rökdykning har en hierarkisk uppgiftsanalys (HTA) genomförts och HTA-diagram har tagits fram för hur rökdykning i underjordiska parkeringshus och industrilokaler ser ut idag. Baserat på dessa HTA-diagram har nya analyser genomförts som har resulterat i kompletterade HTA-diagram som beskriver hur en rökdykningsprocess som inkluderar FUMO kan se ut. Resultatet visar att FUMO kan genom utforskning och lokalisering av branden innan rökdykarpar går in, bidra med en säkrare arbetsmiljö för rökdykarna. / When smoke diving in large buildings, firefighters struggle with disorientation, vast distances and locating the fire itself. This thesis explores the usability and role of a surveillance robot, FUMO, when smoke diving in industries and underground parking lots. By interviewing firefighters and conducting a hierarchical task analysis (HTA) on smoke diving in both underground parking lots and industries, it has been found that FUMO in its basic module can aid firefighters in planning and locating a fire. Based on the HTA describing the current work process of smoke diving, two iterations were conducted to create an HTA with part-goals allocated to FUMO for each environment. These HTA shows how FUMO can be integrated in the current work process of the firefighters. By exploring the environment and locating the fire before the smoke divers are sent in, FUMO can contribute to a safer work environment for the smoke divers.

With the emergence of the concept of crowdfunding, a new alternative has arisen for non-profit organizations to procure funding for their cause. But several of the issues plaguing non-profits still remain. Attracting people to give in the first place is one major challenge, but retaining the relationship and keeping the donors giving is an even bigger one. This thesis delves into the issue of getting donors to sustain their giving, more commonly known as donor retention. More specifically, this thesis aims to identify what factors are important when aiming to improve donor retention in both charity and crowdfunding contexts. Additionally, the thesis explores what is important in the general structure and content of a non-profit crowdfunding platform, and what possible measures can be taken in order to improve donor retention through the platform. This was achieved by conducting a literature study in the field of donor retention in both a charity as well as crowdfunding context to find important factors as well as measures to be considered. In parallel, 15 interviews were conducted to gather insights on the attitudes, donation habits and motivations of people who had previous experience of giving to charity. In sequence with the interviews, 15 user tests on the crowdfunding platform of the non-profit organization Help to Help were performed. The user tests aimed to evaluate and collect donors' opinions and conceptions of the contents and layout of an existing non-profit crowdfunding platform. From the literature study several factors found to improve donor retention were identified. These were: satisfaction, trust, commitment and involvement. The literature study, interviews and user tests resulted in finding a large number of possible actions to take when constructing a non-profit crowdfunding platform. The measures were summarized and condensed into a collection of recommendations and considerations to take when designing such a platform to increase donor retention. The thesis also identified that crowdfunding components can make a charity website appear more transparent and innovative. Additionally, the thesis found that many donors continue to donate based on their initial conviction. Where the ability to provide proof of where the donations end up and ability to appear transparent were the most cited reasons for deciding to support an organization.

Ludwig Wittgenstein, austrian-born philosopher, wrote that “the limits of my language mean the limits of my world. All I know is what I have words for”. We tend to think so highly of our language because we think so highly about ourselves. Yet imagine be- ing able to communicate emotions without words. Words can’t express the visceral nature of our emotions. Words aren’t enough. How can we experience our emotional world, and others, in a more visceral, primitive way? This project proposes the creation of a new sense, using embodied technology, to allow human beings to have a different experience of each other’s emotions, through the study of the long distance relationship scenario. In this human augmentation scenario, design, and specially speculative design have an inherent power to create discussion, awareness and bring attention to how the new developed technologies could affect our existence. This project is meant to ask questions rather than nd a solution. It is meant for ev- eryone who is ready to think about the future of human beings and our evolution as a species. This document presents an overview of the ve (5) months project while detailing the extension of the work and exploration of the product proposed for emotional human augmentation.

Chronic pain is a common condition that people struggle with on daily basis and many strive to find ways to relive their pain. With the development of wearables and smart garments we are now moving from designing an object to be used, to an object to be worn. Technology is an extension of the body and the interaction in itself also becomes part of our body. This development enables different kind of treatments to be implemented in a wearable. Accordingly, this study have investigated if an interactive experience using heat and guided meditation with a wearable can support individuals living with chronic pain, and to what extent the experience can change the perception of pain. The results indicate that an interactive experience including these modalities can have the ability to change perception of pain. The study also suggests implications for design by presenting design qualities that become important in such a design, which resulted in; distraction and immersion, familiarity and practice, personalization and flexibility.

Möjligheten att snabbt kunna utvärdera system är något som blir alltmer aktuellt och populärt. Två metoder som ofta kombineras för att kunna få svar på användares upplevelse och specifika problem med system är användbarhetsenkäter och prototyptestning. Frågan är dock om det finns någon användbarhetsenkät som utvärderar lo-fiprototyper bättre än andra, och hur pass lika lo-fiprototyper utvärderas av olika användbarhetsenkäter. Denna uppsats handlar om hur pass lika användbarhetsenkäterna System Usability Scale (SUS) och Post-Study System Usability Questionnaire (PSSUQ) utvärderar en lo-fiprototyp och om det finns några praktiska skillnader med enkäterna som underlättar eller försvårar när man utvärderar en lo-fiprototyp. Lo-fi-prototypen som testades var en tidig, pappersbaserad version av en att-göralista för handläggare. Testdeltagarna fick först testa att utföra ett par scenarion och interagera med prototypen under 10-15 min, de fick sedan fylla i båda enkäter. Resultaten visade på indikationer att poängen som produceras av SUS och PSSUQ vid lo-fiprototyptestning är lika, men att det skulle behövas vidare studier med fler testdeltagare för att kunna säga detta säkert. Vidare hittades även frågor i PSSUQ som i regel inte testas i lo-fiprototyper, men PSSUQ:s möjlighet till blanksvar kan vara en fördel när tiden som användaren haft med systemet varit begränsad.

This thesis explores how to design for the visually impaired. During the course of work, a literature study and interviews with blind and visually impaired people were conducted. The objective was to investigate what contextual information is wanted in new and unfamiliar spaces outside their home. The interviews also explored how they experience digital tools they are using today and what they think of the possibilities of voice and other user interfaces. The main finding from the study is that there are indications that multimodal interfaces are preferred. The interface should combine voice, haptic and graphics since the participants wanted to interact in different ways depending on functionality and context. Three main problem areas were identified, navigation, public transportation and shopping. Another result was that when developing for the visually impaired it should always be tested on people with a wide variation of vision loss to find the correct contextual information.

Gotlands Slagteri är ett företag som bedriver produktion av kött och charkvaror. Verksamheten bygger på långsiktiga relationer mellan såväl leverantörer som kunder, och som vilken relation som helst krävs omtanke och underhållsarbete för att de skall kvarstå. Syftet med den här studien är att titta på Gotlands Slagteris leverantörsrelationer och göra en utomstående bedömning för slakteriets räkning, samt att se om dokumentationshanteringen av leverantörerna kan förbättras. Syftet mynnar följaktligen ut i tre frågeställningar; Hur ser nuläget av relationen mellan Gotlands Slagteri och deras leverantörer ut? Vilken leverantörsinformation önskas av Gotlands Slagteri i framtiden? Är CRM-system ett lämpligt alternativ för Gotlands Slagteri att dokumentera information i och hur kan det tillämpas? Metodiken som använts för införskaffande av data har primärt bestått av intervjuer, både med leverantörer och personal vid Gotlands Slagteri. Studiens frågeställningar resulterar i att relationerna över lag ser bra ut. Det viktigaste för leverantörerna visar sig vara att avräkningspriserna per djur inte är för låga. Studien resulterar också i att slakteriet inte nödvändigtvis är ute efter någon ny information angående leverantörer i framtiden, men att det istället går att utöka leverantörers redan befintliga uppgifter genom att integrera annan sparad information. Vid integrering av vederbörande uppgifter talar resultatet även för att CRM-system är lämpligt vid framtida dokumentation för leverantörsuppgifter. Återstående för slakteriet är att avgöra vilken typ av CRM-system som ter sig bäst lämpat, men studiens rekommendation är att satsa på ett egenutvecklat system. Initialt kan systemet implementeras vid inköpsavdelningen som ett slags pilotprojekt för att därifrån expandera programmets funktioner till att även stödja andra avdelningar i verksamheten. / Gotlands Slagteri is a butchery which produces meat and charcuterie. The company is dependent on long term relationships with suppliers as well as customers, and just as in any relationship it is nurtured by tender and care. The purpose of this study is to identify the relationship with the suppliers and see what could be improved upon. In this case, the improvement regards the company’s way of handling information about suppliers, which in turn generate the following questions; does any further information regarding suppliers, valuable enough to be documented exist? How could present information be stored? The information procured attempts to answer what makes suppliers supply to Gotlands Slagteri as well as what the viewpoint of other butcheries is. Via a literature study CRM is proposed as a possible solution and is backed up by a benchmark of what similar companies do (HKScan, KLS, Hälsingestintan). CRM systems turn out to be a recurrent option and could be procured either by buying an already existing product or be developed on your own. The study concludes in there not necessarily being anything new to add as far as information per supplier go, but instead point to the fact that there are some already existing data which potentially could add individual value. Beyond that the study show that CRM could make a strong case as a future feature. The one thing reaming is for Gotlands Slagteri to determine which CRM-system would make the better fit.

What transportation means corporations choose for satisfying their mobility needs may have an essential impact on the environment. Choosing environmental friendly, alternatives such as battery driven light electric vehicles, would mean drastically contributing to a more sustainable environment. Meanwhile as carsharing solutions, continuously rise in popularity together with other sharing economy business models so do their possibilities to satisfy the mobility needs for corporations either by them implementing their own carsharing service or by investing on external services offered by established carsharing operators. This thesis has investigated and designed for a Zbee based corporate carsharing service, to be used between the affiliates of Vinngroup in Gothenburg. A Zbee is a light electric three-wheeled vehicle. Based on user-centred service design methods, methods suggested for sharing economy solutions, as well as user experience design methods, this thesis identified that users have different individualistic needs in a workplace and prior experiences that affects how they will use the service.In order to satisfy these different needs, it was found, the system needs to provide real-time vehicle and scheduling information for ensuring the users vehicle availability and service reliability, being one of the first requirement from the users. Further the service should provide users with functions that help users through the different use phases that were identified during this work. The findings found were then presented visually by designing mobile application prototypes and testing them on participants iteratively. The final set of prototypes was further evaluated by using the System Usability Scale, an effective and popular tool for measuring the usability of products and services. This evaluation gave the scores 77.5, 92.5, 90, 87.5 and 72.5, thus this giving a mean-value of 84 and a median of 87.5. All these scores suggests the prototype has high usability.

Studien bottnar i en insikt om att universitetsstudier samt inlärning av kurslitteratur kan vara svårt för studenter. Syftet är att undersöka vilka faktorer som är viktiga vid design av en mobilapplikation som är till för att underlätta för studenter vid inläsning av kurslitteratur. I denna studie har fakta från tidigare forskning kombinerats för att skapa en prototyp. Prototypen har sedan testats av potentiella användare. Testet kompletterades med frågeformulär, skattningsskalor samt intervjufrågor. Avgränsningar i den här studien har inneburit att i prototypen endast testa en liten del av vad som sägs hjälpa kring minnestekniker och priming för att lättare ta till sig en text. Färdiggjorda primingövningar eller stödbilder skapades utan användarna för att se om primingen av ord kunde hjälpa vid inläsning av kurslitteratur. Tidigare forskning belyser studenters svårigheter inför mängden kurslitteratur som behöver läsas in. Inspiration har hämtats från olika typer av minnestekniker, så kallade mnemonics, med en förhoppning om att dessa ska underlätta vid inläsning av ny litteratur och på så vis öka eller bibehålla motivationen. Andra aspekter som tas upp är bilder och memorering, priming för att ta till sig en text lättare, mobilapplikationer med miniövningar för dagens pressade scheman samt motivation. I teorin har vi tittat på motivation, främst inre motivation med stöd från Kellers ARCS modell som bygger på uppmärksamhet, relevans, självförtroende och tillfredsställelse. Resterande teoridel tar upp inlärning, feedback och studiestrategier. Detta är en kvalitativ studie där fakta har samlats in från litteratur för att skapa en prototyp med primingövningar. Prototypen och övningarna hade som syfte att förbereda en student inför läsning av en text. Resterande empiriska data har samlats in från fem potentiella användare. Resultatet visar hur de potentiella användarna upplevde användningen av prototypen samt belyser deras allmänna åsikter om sina egna studier. Användarnas upplevelse av prototypen visar inte en helt klar fördel för en sådan här typ av hjälpmedel. En del användare fann inte nyttan av applikationsprototypen fullt ut, vissa graderade nyttan med värdet 4 av 7 eller högre i skattningsformuläret och en person visade en tendens till att prototypen gjorde nytta även för motivation till fortsatta studier. Utöver detta visade intervjuer på att en motivation till att studera var att öka möjligheten till jobb i framtiden. Det visade sig även att kurslitteratur inte alltid användes utan studenterna tog in information på annat sätt. Tre av deltagarna angav att förberedelser inför en examination ofta skedde dagarna innan deadline, dock är det oklart hur deltagarna tolkade meningen av “förbereda sig inför”. En reflektion till denna studie är att förbättra tydlighet angående mobilövningarna och koppling till texten som hörde till övningarna. Om detta var mycket oklart för användarna kan detta ha påverkat resultatet. / The study is based on the fact that university studies and reading course literature can be difficult for students. The purpose is to investigate what factors are important in designing a mobile application that is designed to facilitate students when reading course literature. In this study, the facts of previous research have been combined to create a prototype. The prototype was tested by potential users. The test was supplemented with questionnaires, estimates and interviews. Delimitations in this study was that in the prototype only parts of memory techniques and priming is being tested. The exercises used in the test were put together without any involvement from the users to see if priming of words can help students with learning. Previous research addresses the problem of absorbing knowledge from a large amount of course literature. Inspiration has been taken from different types of memory techniques, so-called mnemonics, with the hope that these will facilitate the reading of new literature, thus increasing or maintaining motivation. Other aspects that are addressed include images and memorizing, priming for understanding a text easier, mini-exercises in smartphones tailored for today's pressed schedules as well as motivation. In theory, we have looked at motivation, primarily intrinsic motivation, supported by Keller's ARCS Model based on attention, relevance, confidence and satisfaction. The additional theory part takes up learning, feedback and study strategies. This is a qualitative study where facts have been gathered from literature to create a prototype with priming exercises. The prototype and exercises were intended to prepare a student for reading a text. The empirical data was collected from five potential users. The result shows how the potential users perceived the use of the prototype as well as briefly about their general opinions about their own studies. The user's experience of the prototype does not clearly show the benefit of such a type of device. Some users did not fully find the utility of the app, some found it moderately helpful, and one person showed more clearly the prototype also contributed to motivation for further studies. In addition to this, the interviews showed that motivation to study was to increase the possibility of getting a job in the future. It also turned out that course literature was not always used but the students found the necessary information in another way. Most participants indicated that preparation for an examination often occurred the days before the deadline, however, it is unclear how the participants interpreted the meaning of "prepare yourself". A reflection of the study is to improve clarity regarding the mobile exercises and connection to the text that belonged to the exercises. If this was very unclear to users, it may affect the result.
