Målet med detta arbete har varit att undersöka möjligheten att utveckla och formulera en affärsidé och undersöka affärsmöjligheterna för den Taxi Service och app som Jimmy Wickström och Nico Ghatoore utvecklar som en del i deras kandidatexamensarbete. Detta har undersökts genom att utveckla affärsidéer och affärsmodeller tillsammans med Nico och Jimmy och sedan ta fram en detaljerad affärsplan för dessa och testa den teoretiskt och se huruvida den håller måttet och verkar rimlig. Undersökningen har visat att den har möjligheter att lyckas såvida de tre stora taxibolagen Taxi Stockholm, Taxi 020 och Taxi Kurir är villiga att köpa kunder för att fylla upp deras lediga kapacitet. / The goal of this project has been to investigate the possibility to start a business out of the Taxi-service and application Nico Ghatoore and Jimmy Wickström are developing as a part of their bachelor thesis. This goal has been reached by formulating business ideas and developing business models together with Nico and Jimmy and later written a detailed business plan according to the current standards and thus evaluating the quality of the business idea. This has shown us that it is possible to succeed given that the three largest taxi operators are willing to buy customers to fill upp their extra capacity.

Energy conservation and efficiency are often widely touted as non-controversial, cost-positive methods of reducing energy consumption and its associated environmental effects.  However, past programs to encourage residential energy efficiency and conservation have failed to make an impact.  A growing amount of research identifies energy feedback as a method to provide consumers with the information and motivation necessary to make appropriate energy-saving decisions.  JouleBug is a social, playful, mobile smartphone application designed to help users in the U.S. reduce energy consumption and live sustainably through behavioral changes.   This project initiated the design of an energy feedback system for JouleBug that provides estimates of a user’s energy savings for completing 38 residential energy saving actions.  Mathematical models were developed to estimate JouleBug users’ energy savings for each of the energy saving actions, based on 13 input parameters. A method was developed to aggregate each of the savings actions across various energy end-uses into a summary of the user’s energy savings over a given time period.  Additionally, the energy models were utilized to analyze an average user’s potential energy, cost, and greenhouse gas savings over a year. Research into the design components of effective feedback systems was applied in the context of JouleBug to compliment the engineering work.  The components of frequency, measurement unit, data granularity, recommended actions, and comparisons were examined.  Design suggestions based on these components that utilized the energy models to provide effective energy feedback to JouleBug’s users were proposed.  Finally, this report describes opportunities for future research using simple energy modeling methods to provide effective consumer energy feedback in a mobile smartphone application.

Short Message Service (SMS) is a permanently available service on mobile phone networks. In addition to text messages, it supports binary messages to provide various services to mobile phones. SMS security has a strong relationship to the security of mobile phones. Due to the open functionality of mobile phone networks, SMS can be exposed to dierent kind of attacks. To cope with the increasing demand for secure SMS, it is crucial to perform a vulnerability analysis of SMS-implementations to nd out potential security vulnerabilities that smartphones may be exposed to. Conducting vulnerability analyses of SMS is dicult, as one would need to send a large amount of SMS through the mobile phone network in order to conduct such analyses. However, if the need for a mobile phone network is removed from the vulnerability analysis, the diculties of performing it can be considerably reduced. Collin Mulliner and Challie Miller (2009) presented a testing platform (without the engagement of a mobile phone network) for this purpose in three popular mobile phone operating systems: the iPhone, Android and Windows Mobile. They claimed that their testing platform could be ported to other smartphone operating systems (OS). Since the Symbian operating system is one of the most popular smartphone platforms, this thesis focuses on how to port this testing platform to the Symbian OS for vulnerability analysis of SMS-implementations. The research methodology behind this study was an experimental research method, conducted by presenting a hypothesis and developing an artifact to test it. This research produced a key finding: that it is not feasible to implement this vulnerability analysis for SMS-implementations on the Symbian OS, when considering the prerequisites that Collin Mulliner and Charlie Miller dened in their work. They claimed that, if there is an application level access to the serial line for the modem or the ability to add or remove the arbitrary driver, then it is feasible to port their testing framework to other operating systems. This research discovers that neither of these conditions exists in the Symbian OS.

When it comes to calculating physical activity, nowadays a wide variety of tools is at our disposal.The phones used daily incorporate functions that calculate, for example, the number of steps taken throughout the day. Using the tools to set personal goals or to review which physical properties deviate. This work entails collecting data via a mobile camera using an application with the ability to measure luminance for the purpose of calculating heart rate. This thesis is done on behalf of Mobistudy, who wishes to calculate the heart rate during a common exercise test, the Queen’s College Step test. This is intended for use with a telephone held in the hand with the camera's index finger throughout the period, and the light intensity signal is affected by movement disturbances. The purpose of this work is to detect the heart rate in a way that is robust to these disturbances. The results were presented and, in the thesis, it was concluded that the majority of disturbances could be removed, but with the exception of a few tests.

The viewing experience of news videos differ depending on if the device used is a smartphone or a traditional TV, e.g. because some social situations for smartphones not allow audio to be used while watching. Can the adding of subtitles keep the perceived quality at the same level even in these situations? This study investigates the research question how the viewing experience of news videos on smartphones is affected by subtitles and text for young adults. The results are relevant for anyone aiming to improve the viewing experience of videos on smartphones. The study is based on the theory about the concept Quality of Experience, QoE. The method has an experimental approach: 64 participants watched three news videos and after subjective and objective QoE was measured. The conclusion is that subtitles increased every aspect of subjective and objective QoE in a public context when the videos were watched without audio, while they in a home context where audio was present, did not affect any aspect of QoE, except for a decreased willingness to continue watching. / En tittarupplevelse varierar beroende på om tittandet görs på en smartphone eller på en traditionell TV, bland annat eftersom några tittarsituationer på smartphones socialt sett inte tillåter användning av ljud under tittandet. Kan undertexter göra att den upplevda kvalitén behålls på motsvarande nivå även i dessa situationer? Denna studie undersöker frågeställningen hur tittarupplevelsen av nyhetsklipp på smartphones påverkas av undertexter och texter för unga vuxna. Dess resultat är relevanta för alla som ämnar förbättra tittarupplevelsen på smartphones. Studien är baserad på teori om begreppet ”Quality of Experience”, QoE. Metoden har en experimentell ansats: 64 deltagare tittade på tre nyhetsklipp och därefter mättes den subjektiva och objektiva kvalitén på upplevelsen. Slutsatsen är att undertexter ökade varje aspekt av subjektiv och objektiv upplevd kvalité i en offentlig miljö där klippen sågs utan ljud, medan i en hemmiljö – där klippen sågs med ljud, påverkade inte undertexterna någon aspekt av kvalitén, förutom att viljan att titta klart minskade.

The presentation of the search result information has become more important ever since the rapid development and use of smartphones. This thesis investigated what makes search engine result pages efficient and effective on the smartphone screen. For this thesis an experimental study of Karolinska Institutet’s search solution was executed. Three different versions of Karolinska Institutet’s search engine result pages were developed, by researching potential features that would improve the effectiveness and efficiency. The developed versions were compared to the original search engine result pages through experiments with students from Karolinska Institutet. The quantitative results showed no statistical significance of improvement in effectiveness or efficiency. The qualitative results indicated that categories and summary texts are preferable features in a search GUI in a smartphone. Thus the results were indecisive, the author reflects and provides ideas on how to achieve clearer results. / Hur man presenterar sökresultat har blivit allt viktigare i och med dagens av smarttelefoner. Det här arbetet undersökte vad som gör sökresultatssidor effektiva när man använder en smarttelefon. I arbetet utfördes en experimentell studie av Karolinska Institutets söklösning. Tre olika versioner av Karolinska Institutets smarttelefonsgränssnitt utvecklades genom att undersöka potentiella \emph{features} (funktioner, egenskaper) som förbättrar effektiviteten. De olika utvecklade versionerna jämfördes mot det original som Karolinska Institutet använder idag. Detta gjordes genom experiment med studenter från Karolinska Institutet. De kvantitativa resultaten kunde inte visa på någon statistisk signifikant effektivitetsförbättring. De kvalitativa resultaten pekade på att kategorisering och summeringstexter är föredragna features i ett sökgränssnitt i smarttelefonen.

Mobile data traffic will continue to show rapid growth in the coming years; however the data revenue is not rising fast enough to ensure the operators’ profitability. Therefore, mobile operators must seek new approaches to find out what service does the customers need and what quality makes the customers satisfied in order to keep their increasingly sophisticated customers satisfied at the same time minimizing their revenue gap. This paper investigate the effect of mobile cellular network performance and contextual factors on smartphone users’ satisfaction, this was done via crowdsourcing through an experiment where an Android Application and a user Survey were included, which is able to evaluate and analyze the perceived quality of experience (QoE) for YouTube service for Android Smartphone users. To achieve this goal, the App NPT performs measurements of objective quality of service (QoS) parameters, whereas the survey carriers out collecting subjective user opinion. The result show that network performance parameters do impact the MOS (Mean Opinion Score) exponentially, either in a positively or negatively way, however, multiple parameters need to be considered together in order to draw a more accurate correlation with QoE. In addition, QoE are heavily affected by many other contextual factors, such as age and gender as well as users location. QoE are also impacted by several subjective factors, such as user expectation. Not always the highest throughput will lead to the best QoE, and not always the best technology (LTE) deserves the best MOS. Even though user received very high downlink throughput, their MOS value may still be low due to they might think the video were not fun to watch and the quality has not meet their expectation.

Mobilapplikationer till de datorliknande mobiltelefonerna kallade Smartphones är i dagsläget en expanderande marknad. Att utveckla en bra mobilapplikation ställer dock höga krav på utvecklaren. I den här rapporten genomförs en litteraturstudie för att ta fram en Utvecklingsprocess för utveckling av en business-to-businessinriktad mobilapplikation. Syftet med Utvecklingsprocessen är att den ska kunna användas som ett hjälpmedel under utvecklandet. Processen riktar sig framförallt till studenter och företag som inte har någon erfarenhet av att utveckla business-to-businessinriktade mobilapplikationer. Denna process tillämpas sedan praktiskt genom att ta fram en idé till en applikation. Detta för att kunna utvärdera processen med avseende på fyra utvärderingskriterier: Användarvänlighet, Inblick i slutanvändarens behov och problem, fasernas nödvändighet och om den Uppfyller sina syften. Resultatet visar att Utvecklingsprocessen tar upp viktiga aspekter vid utveckling av en mobilapplikation. Det är dock viktigt att hela tiden följa upp arbetet och återkoppla till processen. Detta för att uppdatera och förbättra mobilapplikationen då utvecklaren med stor sannolikhet kommer hitta nya problem och bättre lösningar under utvecklingens gång. Rapporten rekommenderar slutligen att utvecklaren anpassar Utvecklingsprocessen efter sina egna förutsättningar för att uppnå bästa resultat.

I föreliggande litteraturöversikt behandlas bakomliggande fenomen till oreflekterat samt problematiskt smartphonebruk hos elever. Syftet med litteraturöversikten är att undersöka bakomliggande fenomen ur ett fenomenologiskt perspektiv och att synliggöra potentialen för ett fenomenologiskt förhållningssätt i bildundervisning. Forskningsfrågorna är: Vilka fenomen kan vara bakomliggande då eleven uppvisar svårighet till att lägga ifrån sig smartphonen under lektionstid? samt Hur skulle ett fenomenologiskt förhållningssätt kunna användas i bildundervisning?. Resultatet av litteraturöversikten redogör för de tre fenomenen fear of missing out, nomophobia och online identitet och hur dessa kopplas till den komplexa användningen av smartphones med effekter vilka kan påverka individens fysiska och mental hälsa. Vidare presenterar studien förslag till hur dessa fenomen kan hanteras inom en skolkontext samt förslag till inkludering av ett fenomenologiskt förhållningssätt i bildundervisning. Förslaget till fenomenologiskt förhållningssätt i bildundervisning är utvecklat från de metoder som använts i de undersökningar som granskats och bygger på en semistrukturerad uppgift där livsvärlden undersöks med hjälp av metaforer.
