The use of social media and its accessibility through smartphones is becoming a more and more researched topic in the field of ICT. In relation to this, the current study attempts to shed light on the general use of social media, Facebook in particular, by youth in Danish context and pays attention to how the accessibility to this media through smartphones affects the interaction between individuals when being together. The research finishes with three conceptual models which goal is to provide future design implications of the studied ICTs in a way that closer meets the user needs and requirements. The models are – one related to Facebook, one general application, and one related to supporting many-to-many communication. The study is of interpretative nature, based on qualitative research approach with a main method for data collection being qualitative semi-structured interviews. There were 8 interviews performed – 3 with students at a secondary school in Odense, Denmark, and the rest with students at the university in the same town. In this way an understanding of the use patterns and issues experienced by the different age groups was attempted. Furthermore, the study contributes with findings to certain discrepancies identified in the current literature, such as the need for context-aware devices, type of friends on Facebook and others. Finally, due to the limited source for data collection, the thesis does not claim for generalizability, but it should be viewed as a small contribution to the studies related to Facebook, particularly applicable within a Danish context.

Smartphones are often used in order to make purchases today and mobile payments are estimated to continue growing in numbers the following years. This makes mobile payment systems attractive to companies as a new business platform. It also increases the number of malicious users trying to exploit the systems for financial gain. This thesis is conducted for the company TaxiCaller which desires to integrate mobile payments into their existing service. It discusses the current security standards for mobile payments and evaluates existing mobile payment solutions. The focus of the evaluation is on the security of the solutions and vulnerabilities, as well as mitigations of identified vulnerabilities, are discussed. Based on the evaluation, a mobile payment solution is designed and implemented. This system fully integrates with TaxiCaller’s existing system. A threat analysis of the implemented mobile payment solution is performed to provide confidence in the security. This thesis also provides an insight into the ecosystem of mobile payments including the stakeholders, the regulations, the security standards and difficulties during implementations.

Gathering statistics in sports is a tool to provide useful information to different parties such as trainers, club executives and spectators. They have in some instances also become mandatoryas a part of a national association. In order to provide a digital tool to improve the gathering for one such club, a web-based prototype was developed. This prototype was based on specifications outlined by an ice hockey club in the Swedish Allsvenskan division and on previous research on mobile devices. It was tested in two iterations. The result of the tests indicates that a digital, platform independent software not only helps greatly reduce the workload but also provides new abilities and benefits for the clubs.

The quantity of cell phone applications or mobile apps have seen an upsurge at an exponential rate in under a decade. Many have been created for a variety of industries, including transportation. The advent and subsequent commercialized implementation of near-instant transport by a middleman-type of app is now known as a Transportation Network Company or TNC. Examples of the more renowned TNCs are Uber, Lyft and Sidecar. In recent years, TNCs have cultivated a tremendous following, to the degree of taxicab desertion. Moreover, the massive success of TNCs led to expansion of its capacities into public transportation. The TNC’s expeditious popularity has garnered the attention of government and transit agencies. Without fail, TNCs can complement, supplement or compete with transit. However, sparsely has there been any deep discussion about a TNC potentially supplanting transit. The aim of this paper is to show how TNCs could replace public transportation in the United States if subsidized at the same level of transit agencies. Austin, Texas was analyzed as the case study city. A comparison of subsidization between Austin’s transit agency: Cap Metro, the local TNCs, and on a national aggregate level was conducted. The evidence herein clearly shows that TNCs are highly competitive when in revenue service operating at full capacity, potentially replacing public transportation.

The goal of this thesis is to develop a smartphone application for augmented reality view; it is an initial attempt to realize a driver assistance functionality using just a smartphone and an external lens. Initially it depicts a brief analysis about the most feasible development technologies for mobile application development, selecting a proper lens and positioning of the smartphone in the car. Later, it discusses the strategies for real-time object detection using OpenCV; the video frames are processed using the strategies to find patterns in the videos. Different techniques like Hough-line transform, watershed, contour detection, color segmentation, color thresholding and HAAR cascades are implemented and compared in terms of real time detection of the desired objects. Then a unified algorithm is implemented for the given scenario which overcomes the challenges faced during the conceptualization phase. Finally, the results are depicted with the snapshots of the real time detection done from the smartphone and then evaluated against the vision of the application and the achieved tasks. This thesis is concluded by stating the prospects of this mobile application in the future.

The theoretical part deals with the basic concepts of mobile devices such as smartphone and sporttester and their development and function. The practical part analyzes the mobile running application that are available on the market and their comparison in pursuance of questionnaire survey. Conclusions are made from the questionnaire survey that correspond to another aim of the master thesis. At the end of the work the master thesis deals with a set of recommendations which was established from long-term testing of mobile running applications. The main asset of work is formulate optimal aspects of the running applications and their usage while running as well as own evaluation of tested mobile running applications.

Bakgrund: I dagens samhälle ligger inte fokus bara på den fysiska produkten utan även på konsumentbeteendet och värdet av ett varumärke. Varumärken bär på symboliska värden som konsumenter använder sig av för att identifiera sig själva och skapa gemenskaper, även kallat Brand communities. Idag påverkas konsumenter mindre av reklam och produktplaceringar och marknadsförare arbetar därför ständigt med  att tolka konsumenter och vad som motiverar deras konsumentbeteende. Syfte: Syftet med studien är att undersöka vilka bakomliggande faktorer som motiverar konsumenter till att välja en smartphone. Frågeställningar: Vilka faktorer är motiverande för kunden när de väljer att köpa en smartphone? Vilken av dessa faktorer är dominerande för kunden? Hur påverkar den dominerande faktorn konsumenten? Metod: Studien baseras på en kvalitativ forskningsstrategi. Uppsatsens metodologiska ansatser utgör ett förhållande mellan teori och praktik och fortsättningsvis har forskningsstrategin utgått från en deduktiv ansats. Studien har tillämpat källtriangulering via två fokusgruppsintervjuer med åtta personer och kompletterats med tre telefonintervjuer med tre olika försäljare. Slutsats: Slutsatsen visar att samtliga kulturella, sociala och psykologiska faktorer motiverar konsumenter till att välja en smartphone, dock är den främsta påverkande faktorn konsumentens vänner som tillhör kategorin för de sociala faktorerna. Konsumentens vänner introducerar konsumenten för nya produkter, varumärken och trender. Tillhörande de sociala faktorerna finner vi även status och roller. Smartphones associeras med vissa värden såsom exklusivitet och kan bli ett hjälpmedel för att att uppnå en viss status eller leva upp till en viss roll. Detta skapar sedan preferenser och associationer hos konsumenten som driver den till att välja en smartphone. / Background: In today's society, not only is the focus on the physical product but also on the behavior of the consumer and the value of a brand. Brands carry symbolic values ​​that consumers use to identify themselves and create communities, also known as Brand communities. Today, consumers are less affected by advertising and product placements and as a result, marketers are constantly working to interpret consumers and what motivates the consumer behavior. Purpose: The aim of the study is to investigate the underlying factors which motivate consumers to choose a smartphone. Issues: What factors motivate the customer when they choose to buy a smartphone? Which of these factors are dominant for the customer? How does the dominant factor affect the consumer? Method: The study is based on a qualitative research strategy. The methodological approaches of the study constitutes a relationship between theory and practice and, as a consequence, the deductive approach has been selected. The study has applied source triangulation through two interviews with a focus group consisting of eight people and supplemented with three telephone interviews with different sales representatives. Conclusions: The conclusion shows that all cultural, social and psychological factors motivate consumers to choose a smartphone. However, the main influencing factor is consumers friends who belong to the category of social factors. Consumer friends introduce the consumer for new products, brands and trends. Among the social factors we also find status and roles. The smartphone is associated with certain values ​​as exclusivity and can be a tool for achieving a certain status or living up to a certain role. This then creates preferences and associations of the consumer that drives it to choose a smartphone.

Mobiltelefonens mångfacettering erbjuder många möjligheter inom studier, men även flera utmaningar. Den här studien har utgått ifrån en sociokulturell teori om lärande, där det endast går att förstå eller undersöka människors tänkande eller kunskaper genom en analys av språk och handlingar, i relation till sociala och kulturella resurser som används av människan. I detta fall mobiltelefoner. Studien baserades i uppbyggnaden av fallstudier, då det som undersökts är ”hur” och ”varför” ett aktuellt skeende i ett konkret socialt sammanhang ser ut som det gör. Studiengenomfördes även med influenser av symbolisk interaktionism, detta då mänsklig interaktion sker bland annat med hjälp av symboler och mobiltelefonen i sig kan ses som en symbol, likväl som denger tillgång till andra symboler. Då en djupare förståelse för attityderna och uppfattningarna rörande mobilanvändandet i sociala sammanhang eftersträvades var denna studie kvalitativ och utfördes med semistrukturerade intervjuer som metod för insamling av data. Intervjupersonerna kan både se för- och nackdelar med att använda mobiltelefoner i studier, bland annat mobiltelefonens lättillgänglighet och mobilitet, men även det negativa i att olika sociala medier kan pocka på uppmärksamheten och störa koncentrationen både för mobiltelefonens ägare och även andra personer i dess närhet. Dock välkomnas teknik som kan förenkla studierna, men mobiltelefonen i dag saknar anpassning till detta, vilket gör att den därmed inte är en självklar del inom utbildning och studier. / <p>Godkännande datum: 2017-06-02</p>

A Wearable Mobility Monitoring System (WMMS) can be an advantageous device for rehabilitation decision-making. This thesis presents the design and evaluation of a proof-of-concept WMMS that uses the BlackBerry Smartphone platform. A Java program was developed for the BlackBerry 9550, using the integrated tri-axial accelerometer, Global Positioning System sensor (GPS), CMOS digital video camera, and timer to identify change-of-state (CoS) among static states, dynamic states, small activity of daily living (ADL) movements, and car riding. Static states included sitting, lying, standing, and taking an elevator. Dynamic states included walking on level ground, walking on stairs, and walking on a ramp. Small activity of daily living movements included bathroom activities, working in the kitchen, and meal preparation. Following feature extraction from the sensor data, two decision trees were used to distinguish CoS and mobility activities. CoS identification subsequently triggered video recording for improved mobility context analysis during post-processing.
