News tips are an important resource for journalists and newspapers. Currently, however, there is very little research available with regards to why tipsters send in tips and their needs, as well as the news tip handling process and the challenges of journalists. The purpose of this thesis is, therefore, to explore the motivations behind sending in tips and tipsters’ needs from the news tips process. Additionally, the purpose is to explore the news tips handling process and journalists’ challenges and needs in relation to that process. The project was conducted together with Schibsted Media Group, specifically focusing on one of their newspapers in Norway, Bergens Tidende (BT). The research questions were answered by conducting two interview studies with six tipsters and with six journalists and news staff, respectively. Usability testing of the Bergens Tidende (BT) tips page (bt.no/tips) was also included in the interview study with tipsters. The project resulted in three tipster personas and three accompanying journey maps. The tips handling process was visualised through a tip journey map. Several insights could be gathered, and a set of usability problems were found with regards to the tip page. The results further showed that feedback is an important component of the user experience of sending in a tip. It was also found that filtering tips before they reach journalists plays a vital part in the news tip handling process. / Nyhetstips är en viktig resurs för journalister och tidningar. För närvarande finns det dock lite forskning om varför tipsare skickar in tips och vad deras behov är, liksom hur tipshanteringsprocessen ser ut och journalisters utmaningar i relation till den processen. Syftet med detta examensarbete är därför att utforska motivationen bakom att skicka in tips och tipsares behov av nyhetstipsprocessen. Dessutom är syftet att utforska nyhetstipshanteringsprocessen och journalisters utmaningar och behov i samband med den processen. Projektet genomfördes tillsammans med Schibsted Media Group, med särskilt fokus på en av deras tidningar i Norge, Bergens Tidende (BT). Forskningsfrågorna besvarades genom att genomföra två intervjustudier med sex tipsare respektive sex journalister och nyhetspersonal. Användbarhetstestning av BT’s tipssida (bt.no/tips) ingick också i intervjustudien med tipsare. Projektet resulterade i tre tipsar-personas och tre medföljande användarresor. Tipshanteringsprocessen visualiserades genom en tipsresa. Flera insikter kunde insamlas, och en uppsättning användbarhetsproblem hittades med avseende till tipssidan. Resultaten visade vidare att feedback är en viktig del av användarupplevelsen av att skicka in ett tips. Vidare kom det fram att filtrering av tips innan de når journalister spelar en viktig roll i processen för hantering av nyhetstips.

Recent advances in mobile Augmented Reality (AR) create promising opportunities for novel, engaging, potentially scalable, interactive products. However, evaluating the usability and UX of mobile AR can be tricky given that the interface is highly adaptable, often ambiguous, and varies depending on context. This project will recount the evaluation of a foot scanner that is guided via mobile AR interaction, in doing so offering one way to approach mobile AR evaluation. Some themes that will be discussed are the importance of iterative in-situ evaluation and the benefits of both in-lab and remote usability testing, as well as how to identify user insights given the perceptual complexity and technical ambiguity of mobile AR interaction. Furthermore, design implications to enhance the usability and experiential aspects for mobile AR will be proposed, including how to guide and instruct users, techniques for movement-based interaction design, and how to utilize the various input types in mobile AR. Lastly, an overview of inserting mobile AR user-evaluation in an Agile product environment, including iterative lo-fi testing, insight communication, team collaboration, and the use of evaluation measures, will be discussed. The hopes of this project is to provide a valuable resource to help push future mobile AR designers and evaluators in the right direction. / Nya framsteg inom mobil Augmented Reality (AR) skapar lovande möjligheter for nya, engagerande, intuitiva och potentiellt skalbara interaktiva produkter. Att utvärdera användbarhet och UX for mobil AR kan dock vara svart eftersom gränssnittet ar mycket anpassningsbart, ofta tvetydigt och varierar beroende på sammanhang. Detta projekt kommer att beskriva utvärderingen av en fotscanner som styrs via mobil AR-interaktion och därmed medföra ett satt att närma sig mobil AR-utvärdering. Några teman som kommer att diskuteras ar vikten av iterativ in-situ-utvärdering, fördelarna med användbarhetstestning i laboratorium och på distans, samt hur man identifierar användar-insikter i relation till den perceptuella komplexiteten och tekniska oklarheten i mobil AR-interaktion. Dessutom föreslås designimplikationer for att förbättra användbarhet och erfarenhetsaspekter for mobil AR, inkluderande hur användare kan vägledas och instrueras, tekniker for rörelsebaserad interaktionsdesign och hur man använder de olika ingångstyperna i mobil AR. Slutligen diskuteras en översikt kring att införa mobil AR-användarutvärdering i en agil produktmiljö, inklusive iterativt lo-fi-testande, insikts-kommunikation, samarbete i teams och användningen av utvärderingsmetoder. Förhoppningarna med detta projekt ar att tillhandahålla en värdefull resurs for att hjälpa till att driva framtida mobila AR-designers och utvärderare i ratt riktning.

Utgångspunkten i detta magisterarbete inom ämnet Interaktionsdesign var att se varför barn i dagens skola tycker att skolarbetet blir tråkigare ju högre upp i årskurserna de kommer. Vidare drog jag slutsatserna, utifrån litteraturgenomgång, att någon gång i årskurs 4-6 börjar eleverna i skolan att tappa lusten för skolarbetet. Var det allt skolarbete eller bara vissa ämnen som eleverna tyckte var tråkigt? Varför var det tråkigt? Kunde jag göra något åt saken?

As more and more new e-commerce sites for shoes are being created, it is important from a competitive perspective that the site is perceived as trustworthy. Theintention of this study is to conduct an investigation on how colour schemes affect trustworthiness, based on the following research question: how does the colourscheme of a web application affect how users perceive the trustworthiness of a webshop for buying and selling second-hand sneakers ? To answer this question, a webapplication in the form of a second-hand sneaker shop was developed. The development of the web application was based on theory on perceived trustworthiness,specifically colour choice and its psychological impact on a user’s experience. To testusers’ experience of the web application, user testing was carried out in two phases,the first being a quantitative comparison of different colour schemes in a survey,and the second phase was conducted as a qualitative study. After analysing theresults, the study showed that the choice of the basic colour and its shade influencesthe user’s perception of the website from a trustworthiness perspective accordingto current theory. A blue colour scheme was shown to give the user the greatestexperience of trustworthiness. / Då det idag skapas fler och fler nya e-handelssidor för skor är det viktigt ur ettkonkurrensperspektiv att sidan upplevs för användaren som trovärdig.

Bachelor thesis in Interaction Design by Håkan Carlsson, spring term 2007, MalmöUniversity, School of Arts & Communication.The climate for video sharing online is somewhere in the border of becoming a place for only the big companies to distribute material with general interest, or small communities with genre-specific interest to attract a larger audience. In this article I will look at the travelindustry to see what possibilities can be implemented into communities with interest in planning and travelling. I will argue that the importance of collaboration with different mediacan create a bigger picture so that more people can use and discover each other’s travel videos and experiences. I have also taken a closer look at social interaction at online communities such as MySpace and YouTube. The concept Dtourist is an online travel planner so that people can share experiences and use video as a part of their planning for trips and vacations. If we are to understand what kind of experiences we are publishing we must first look at our own material and understand them fully before we expect that a larger audience can be attracted.

This thesis explores challenges for the design of Virtual Reality Exposure Therapy (VRET) systems. Exposure therapy is the established method for treatment of anxiety disorders and is typically delivered in-vivo, i.e. exposure to phobic stimulus in real environments. Virtual reality (VR), instead, offers the potential to conduct exposure therapy at the clinic. This approach has several benefits in terms of efficiency, customization and control, amount of exposure, and as an transition phase to real situations. However, currently many systems are limited in scope and are designed for research purposes without informing the design from therapist's practices.  My research aims to contribute towards the understanding of current practices in exposure therapy and investigates challenges for the design of these systems for the two main user groups, patients and therapists. Three different focus areas have been prevalent. First, we have studied therapist in real sessions to inform the design and development of VRET-systems. Second, we have evaluated two different VRET implementations supporting therapists to interact with patients. Third, on the patient's side, we have studied presence on healthy participants focusing on the influence of virtual bodies and patient movement in VR. This thesis summarises and discusses these studies. Overall, the studies emphasize the complexity of exposure therapy and the need for individualized patient conditions. This poses multiple challenges for the design of VRET-systems such as, first, the systems must offer flexibility to the therapists to orchestrate individualized therapy. Second, the systems must enable rich therapists-patient interaction. Third, the complexity of individualization of scenarios and sessions must be addressed in the design of the therapist's interface. Fourth, for patients, body avatars influences presence differently depending on the scenario and locomotion is challenging as offices are typically small. / <p>QC 20190214</p>

The previous decade has seen breakthroughs in image analysis and computer vision, mainly due to machine learning methods known as deep learning. These methods have since spread to other fields. This thesis aims to survey the progress, highlight problems related to data and computations, and show techniques to mitigate them. In Paper I, we show how to modify the VGG16 classifier architecture to be equivariant to transformations in the p4 group, consisting of translations and specific rotations. We conduct experiments to investigate if baseline architectures, using data augmentation, can be replaced with these rotation-equivariant networks. We train and test on the Oral cancer dataset, used to automate cancer diagnostics. In Paper III, we use a similar methodology as in Paper I to modify the U-net architecture combined with a discriminative loss, for semantic instance segmentation. We test the method on the BBBC038 dataset consisting of highly varied images of cell nuclei. In Paper II, we look at the UCluster method, used to group sub- atomic particles in particle physics. We show how to distribute the training over multiple GPUs using distributed deep learning in a cloud environment. The papers show how to use limited training data more efficiently, using group-equivariant convolutions, to reduce the prob- lems of overfitting. They also demonstrate how to distribute training over multiple nodes in computational centers, which is needed to handle growing data sizes.

This thesis presents a comprehensive research study aimed at designing an information dashboard to address the specific information needs of dairy farmers in relation to animal health and reproduction data. The research focused on answering two key research questions: (1) How can we determine which factors are most relevant in terms of farms productivity and wellbeing of its animals? and (2) How can we visualize the data and farms history in a meaningful way so that the owner can make sense of it and therefore make better decisions for future planning?To answer these questions, extensive user research was conducted within the dairy farming community, involving interviews, literature review and surveys. The findings revealed that dairy farmers required quick access to critical data related to animal health and reproduction to make informed decisions. Applying a user-centered design approach, iterative prototyping and usability testing sessions were conducted to refine the dashboard design based on feedback from farmers. The goal was to create a user-friendly tool that addressed the specific needs of dairy farmers, including clear differentiation between data pertaining to individual animals versus the entire herd.The outcome of this research was the development of an information dashboard that successfully met the information needs of dairy farmers. The dashboard provided easy access to essential data, empowering farmers to make informed decisions regarding animal health and reproduction.Further testing and refinement of the dashboard design are recommended to ensure its effectiveness and usability in real-world farming scenarios. Additionally, future investigations could explore the inclusion of breeding value information in the dashboard. This research contributes to the transformation of the dairy farming landscape, offering farmers enhanced information management capabilities and improved decision-making processes.
