In modern casinos, personnel exist to advise, or in some cases, order individuals to stop gambling if they are found to be gambling in a destructive way, but what about online gamblers? This thesis evaluated the possibility of using machine learning as a supplement for personnel in real casinos when gambling online. This was done through supervised learning or more specifically, a decision tree algorithm called CART. Studies showed that the majority of problem gamblers would find it helpful to have their behavioral patterns collected to be able to identify their risk of becoming a problem gambler before their problem started. The collected behavioral features were time spent gambling, the rate of won and lost money and the number of deposits made, all these during a specific period of time. An API was implemented for casino platforms to connect to and give collected data about their users, and to receive responses to notify users about their situation. Unfortunately, there were no platforms available to test this on players gambling live. Therefore a web based survey was implemented to test if the API would work as expected. More studies could be conducted in this area, finding more features to convert for computers to understand and implement into the learning algorithm.

Functional connectivity is a field within neuroscience where measurements of co-activation between brain regions are used to test various hypotheses or explore how the brain activates depending on a given situation or task. After analysis, the underlying data in the field consists of a n by n adjacency matrix where each cell represents a correlation value between two regions in the brain. Depending on the research question the number of regions and matrices incorporated varies and new visualizations are needed in order to portray them. In this thesis the design of an interactive web based visualization tool for functional connectivity was explored through an iterative design process. The design of the tool was based on existing guidelines, interviews and best practices in data visualization as well as an analysis of current visualization solutions used in functional connectivity. The final concept and prototype uses a network plot for functional connectivity called the connectogram as well as a grouped bar graph to provide an intuitive and accessible way of comparing functional connectivity data by interacting with and highlighting networks and specific network data through direct manipulation. Results of qualitative evaluations of a prototype using data from a concurrent scientific project is presented. The prototype was found to be useful, engaging, easily perceivable and offered an easy and quick way of exploring data sets.

The ongoing consumer transition from offline to online shopping in the fashion retail industry requires retailers to take action. Not only do consumers shop more online, they also go online for research of retail products. Forecasts tell that bringing the online experience to offline stores might bridge the gap between the two channels. The online experience provides high-end digital content, and puts a demand on the product information offline as this was found crucial for the customer experience. The marketing possibilities in-store was found to be an advantage to bricks-and-mortar retailers. Thus, this study aims to investigate how the customer experience can be enhanced in retail bricks-and-mortar stores through digital product information. A survey was conducted to identify user requirements in terms of product information. An augmented reality prototype was formed to satisfy the identified user requirements. The prototype was tested in two user studies that evaluated the content, visualization, interaction and satisfaction. The prototype was iterated between the two user studies. The most crucial parameters of fashion retail product information were established, together with implications for the visual representation and interaction. It was found that there were unfulfilled user needs with existing service options, which were satisfied with the use of an augmented reality prototype for product information retrieval. The use of AR for this purpose also proved to be able to contribute to an omnichannel solution for multi-channel retailers. The conclusion was thus that the customer in-store experience could be enhanced by the introduction of an augmented reality prototype for product information retrieval, taking into account the implications for content, visualization and interaction provided in this study. / Den pågående konsumentövergången från offline till online shopping i modedetaljhandeln kräver att detaljhandlare vidtar åtgärder. Förutom att konsumenterna handlar mer online, använder de också onlinebutiker allt mer för undersökning av produkter. Prognoser förtäljer att införandet av onlineupplevelsen till offline-butiker kan överbrygga klyftan mellan de två kanalerna. Onlineupplevelsen tillhandahåller högklassigt digitalt innehåll och ställer krav på produktinformationen offline, eftersom denna konstaterades vara en avgörande faktor för kundupplevelsen. Marknadsföringsmöjligheterna i fysiska butiker har visat sig vara en fördel för detaljhandlare som existerar i offlinekanalen. Således syftar denna studie till att undersöka hur kundupplevelsen kan förstärkas i fysiska detaljhandelsbutiker genom digital produktinformation. En enkätundersökning genomfördes för att identifiera användarnas krav när det gäller produktinformation. En augmented reality-prototyp formades i anspråk att tillfredsställa de identifierade användarkraven. Prototypen testades i två användarstudier, som utvärderade prototypens innehåll, visualisering, interaktion och tillfredsställelse. Prototypen itererades mellan de två användarstudierna. De mest kritiska parametrarna för produktinformation fastställdes, tillsammans med implikationer för visuell representation och interaktion. Det kunde konstateras att en AR-prototyp kunde tillfredsställa ännu omötta användarbehov för inhämtning av produktinformation. Användningen av AR för detta ändamål visade sig också ha möjligheten att bidra till en omnichannel-lösning för modehandlare som existerar i flera kanaler. Slutsatsen var således att kundupplevelsen i fysiska detaljhandelsbutiker kan förstärkas genom införandet av en augmented reality-prototyp för produktinformationsinhämtning, genom att ta hänsyn till de implikationer gällande innehåll, visualisering och interaktion tillhandahållna i denna studie.

This thesis project focuses on the creation and usage of external light effects to accommodate the needs of competitive gamers. Prior to the creation of these light effects, the function of audio in films and games was analyzed by examining the works of Michel Chion, who is the leading scholar in studying audio-vision: the relationship between the screen and sound. Subsequently, the possible application of these theories onto the lighting domain was discussed, showing the similarities and usefulness of these two different modalities. The goal of the thesis project was to improve the gamers’ perceived and objective performance in first-person shooter games. A counterbalanced within-group study was conducted; each participant played the game Doom 3 for 25 minutes with and without light effects. Four functional and informative light effects were created to accommodate the in-game content in an attempt to improve their performance. The players were given identical instructions on how to play the game. Four Philips Hue Go lights were placed in a rectangular shape around the participant with the TV in front. An additional Philips Hue LED strip was placed behind the TV. After each session, a standardized Game Experience Questionnaire (GEQ) was used to collect data on the players’ perceived performance. In-game logs were collected to determine how the players fared in combat. A linear checkpoint system was created to judge how far the participants progressed. The GEQ data showed that the light effects improved the players perceived performance. However, the results from the in-game logs and player progression are inconclusive and not statistically significant. The identified potential reasons were the low sample size (n=14), too little practice time, potential differences in player skill and physical light positioning. / Detta examensarbete fokuserar på skapandet och användandet av externa ljuseffekter  för att ackommodera tävlingsinriktade gamers behov. Inför skapandet av dessa  ljuseffekter genomfördes en utforskning av ljudets funktion i film och spel genom att  analysera Michel Chions verk inom audio-vision (eng); det vill säga förhållandet mellan  bild och ljud. Fortsättningsvis diskuterades huruvida dessa teorier kunde appliceras på  domänen ljus, genom att visa på användbarheten samt de likheter som dessa två olika  modaliteter har.    Målet för examensarbetet var att förbättra gamers upplevda och objektiva prestation i  förstapersonsskjutare (eng: First Person Shooter / FPS). En motviktad användarstudie  (within-group) genomfördes. Fyra funktionella och informativa ljuseffekter skapades för  att ackommodera spelets innehåll i ett försök att förbättra spelarnas prestation. Varje  deltagare spelade FPS-spelet ​Doom 3​ i 25 minuter med och utan ljuseffekter. Spelarna fick  identiska instruktioner om spelets grunder. Fyra Philips Hue Go-lampor var utplacerade  rektangulärt runt spelaren med TVn längst fram i mitten. En ytterligare Philips Hue LED  strip var placerad bakom TVn.    Efter varje session användes ett standardiserat Game Experience Questionnaire (GEQ) för  att insamla data av spelarnas upplevda prestation. Data loggades även inifrån spelet för  att uppmäta hur spelarna presterade i strid. Ett linjärt kontrollstationssystem upprättades  för att avgöra hur långt in i spelet deltagarna nådde.    Datan från GEQ-enkäterna visade att ljuseffekterna förbättrade spelarnas upplevda  prestation. Datan från spelloggarna och kontrollstationssystemet gav ett ofullständigt  resultat och var statistiskt insignifikant. De identifierade potentiella anledningarna var det  låga antalet deltagare (n=14), för lite övningstid, skillnader i spelarfärdighet och fysisk  ljuspositionering.

This thesis provides insights into how technology can be and is used as child-centric learning tools within primary school classrooms. The conducted studies look closely at how tablet technology is integrated into the modern classroom, and considers how existing digital writing technologies could support handwriting-based learning exercises in future. This is achieved by conducting three in-the-wild studies, using different approaches, with a total of seventy-four children in school classrooms. In the first study, focus is placed on how tablets integrate into and with existing classroom practices, documenting when and how children use tablets in class. Relevant and complementary to this, the use of traditional writing tools is questioned and two further studies explore the potential and suitability of digital pens to support children's handwriting-based learning. One looks in detail at how children's handwriting is effected by different existing digital pen technologies. The other study, conducted through a creative, participatory design session, asks children to provide their opinions regarding desirable features for digital writing technology. The findings from this research classify and exemplify the role of tablets in the classroom, and explore potential design directions of digital writing tools which could be used by children in the future. This work may be useful and of interest to others who conduct research with children within the fields of Human Computer Interaction, Child Computer Interaction or education.
