Företag har länge kunnat nå ut med information till kunder via traditionella metoder så som sms och e-post. I och med den stora populariteten hos smarta telefoner och sociala medier har information nu blivit extra viktigt. Med detta har det även kommit nyare sätt för företag att kommunicera med sina kunder så som via push-notifikationer till smarta telefoner och webbläsare eller via sociala medier. Projektet beställdes av QT Systems och hade som syfte att ge företaget en bättre inblick i vad de har för möjligheter när det gäller att nå ut med information till deras kunder. Målet med projektet var att finna den metod som bör passa bäst för att just QT Systems fastighetssystem ska kunna notifiera deras användare om olika händelser och att kunna visa att denna går att implementera i detta system. Under arbetets gång bestämdes det att push-notifikationer till en native app skulle vara den bästa lösningen. Det har även gjorts ett ”proof-of-concept” som visar att den valda metoden kommer gå att implementera i QT Systems fastighetssystem och åtminstone nå ut till smarta telefoner som har Android eller iOS som operativsystem. / For a long time companies have been able to reach out to customers by traditionally methods such as SMS or e-mail. The huge rise of popularity in smartphones and social media now makes information more important than ever. With this there are newer ways for companies to communicate with their customers such as push-notifications by native apps and browsers or by social media. This project was ordered by QT Systems with the purpose to give the company a better view of their possibilities when it comes to reaching out with information to their customers. The goal with the project was to find the best method for allowing QT Systems' real estate system to notify their users of certain events and to show that this method can be implemented in this system. During the course of this project it was decided that push-notifications by a native app would be the best solution. A ”proof-of-concept” which shows that this method can be implemented in QT Systems' real estate system and that it can be used for at least Android and iOS smartphones was also done.

This thesis takes the reader on an exploratory journey into the development of impulse purchasing behaviour stemming from the increased usage of web-connected smartphones. At an unprecedented rate, consumers are able to access businesses online, twenty-four hours a day, seven days a week, at their own convenience, without restrictions other than a connection to the World Wide Web. This mobile phenomenon has effectively pushed the commercial market to new boundaries and simultaneously created new possibilities for retailers to reach out to consumers by providing seamless and innovative marketing solutions on portable devices to a fast-growing market segment. This emergent technology and the trends it brings with it, demands special attention to the analysis of consumer behaviourism. As of date, academia has put relatively little emphasis on the evolution of impulse purchasing behaviour as a product of smartphone usage. In this paper, the authors investigate the attitude of local consumers towards so-called ‘push notifications’, whose purpose is to stimulate an impulsive behaviour in the smartphone user. The results of this study show that multiple factors in relation to push notifications on smartphones play an important part in shaping the attitude of consumers and furthermore can elicit impulse buying behaviour. These factors often bridge each other and are at times mutually dependent.

The news landscape has changed during recent years because of the digitization. News can nowadays be found in both newspapers and on different sites online. The availability of the digital newspapers leads to competition among the news companies. To make the users stay on one specific platform for news, relevance is required in the content and oneway of creating relevance is through personalization, to tailor the content to each user. The focus of this thesis is therefore personalizing newspush notifications for a digital  newspaper and making them more relevant for users. The project was made in cooperation with VK Media, and their digital newspaper. The task in this thesis is to implement personalization of push notifications by building a recommendation system and to test the implemented system with data from VK. In order to perform the task, a dataset representing reading habits of VK’s users was extracted from their data warehouse. Then a user-based and content-based recommendation system was implemented in Python.The idea with the system is to recommend new articles that are sufficiently similar to one or more of the already read articles. Articles that may be liked by one of the most similar users should also be recommended. Finally, the system’s performance was evaluated with the data representing reading habits for VK’s users. The results show that the implemented system has better performance than the current solution without any personalization, when recommending a few articles to each user. The results from the evaluation also show that the more articles the users have read, the better predictions are possible to make. Thus, this thesis offers a first step towards meeting the expectations of more relevant content among VK’s users.

A helpful tool in forming, breaking, and maintaining habits and behaviors is a digital behavior change intervention (DBCI). These are interventions that leverage digital technologies to help their users to either take on or avoid certain behaviors. A common problem is a lack of user engagement with the interventions’ content, which is key for its effectiveness. It has however been shown that gamified content and using prompts—such as push notifications—may have the effect of increasing user engagement, for both DBCIs and other applications. Furthermore, two commonly occurring game concepts are competition and cooperation, each with different influences on engagement which in turn may vary depending on the context and the user. Therefore, this thesis set out to examine how push notifications can be used to increase user engagement with a gamified DBCI by making its gamified elements more salient. Additionally, it will investigate if there is any difference in influence on engagement of notifications that either promote competition or cooperation. This was evaluated by deploying two different push notification strategies on Deedster—a gamified mobile DBCI with the aim to get its users to reduce their personal CO2-emissions—and tracking user behavior. The results of the evaluation showed that users who received push notifications were more engaged—started more sessions and spent more time—with the application than users who did not receive any. They also performed a significantly higher amount of target behaviors. There was no difference in the influence on performed target behaviors between the notifications promoting competition or cooperation, and only one significant difference—usage of intervention features—regarding user engagement. The gender of the user was also found to be a considerable factor in the influence of the push notifications. Competition increased engagement more than cooperation for male users, but not for female users. / Ett effektivt verktyg för att forma, bryta eller bibehålla vanor och beteenden är en så kallad digital beteendeförändrings-intervention (eng. digital behavior change intervention eller DBCI). Dessa interventioner använder digital teknik för att hjälpa deras användare att antingen påbörja eller undvika särskilda beteenden. Ett vanligt problem med dessa är att användarna ofta inte är särskilt engagerade i interventionernas innehåll eller funktioner, vilket är viktigt för deras effektivitet. Emellertid har det visats att spelifierat innehåll och användandet av notiser—såsom push-notiser—kan ha en ökande effekt på engagemanget. Två vanligt förekommande spelkoncept är tävling och samarbete, båda med sina olika effekter på engagemang vilket också skiftar beroende på kontexten och användaren. Därför ska detta examensarbete undersöka hur push-notiser kan användas för att öka användar-engagemanget i en spelifierad och mobil beteendeförändrings-intervention genom att göra dess spelifierade element mer framträdande. Dessutom kommer det även undersökas om det är någon skillnad i effekt mellan notiser som antingen främjar tävling eller samarbete. Detta var utvärderat genom att använda två olika push-notis-strategier på Deedster—en spelifierad, mobil intervention som syftar till att minska dess användares CO2-utsläpp—och sedan följa användarnas beteende. Resultaten visade att användare som fick push-notiser var mer engagerade—startade mer sessioner och spenderade mer tid—inom applikationen jämfört med användare som inte fick några notiser. De utförde också signifikant fler önskade beteenden. Det var ingen skillnad i effekt på antalet önskade beteende utförda mellan att främja tävling eller samarbete och endast några få skillnader i engagemang. Dock visade det sig att användarens kön var en betydande faktor i effekten av notiserna. Notiserna som främjade tävling var mer effektiva för manliga användare jämfört med de som främjade samarbete. Denna effekt syntes inte bland kvinnliga användare. / Designing digital technologies for supporting energy-related behavior change in the kitchen
