abstract: Mobile apps have improved human lifestyle in various aspects ranging from instant messaging to tele-health. In the current app development paradigm, apps are being developed individually and agnostic of each other. The goal of this thesis is to allow a new world where multiple apps communicate with each other to achieve synergistic benefits. To enable integration between apps, manual communication between developers is needed, which can be problematic on many levels. In order to promote app integration, a systematic approach towards data sharing between multiple apps is essential. However, current approaches to app integration require large code modifications to reap the benefits of shared data such as requiring developers to provide APIs or use large, invasive middlewares. In this thesis, a data sharing framework was developed providing a non-invasive interface between mobile apps for data sharing and integration. A separate app acts as a registry to allow apps to register database tables to be shared and query this information. Two health monitoring apps were developed to evaluate the sharing framework and different methods of data integration between apps to promote synergistic feedback. The health monitoring apps have shown non-invasive solutions can provide data sharing functionality without large code modifications and manual communication between developers. / Dissertation/Thesis / M.S.

A variety of factors may influence the success and performance of App or a MSECO over time, making difficult the constructions of good solutions to this uncertainty scenario. In this issue, the use of simulation would be an important tool to support decision making, providing in a controlled manner different scenarios in a MSECO and minimizing risk in the pursuit of creating a popular App. In this context, a Systematic Literature conducted in this work identified 19 publications regarding simulation of MSECO. These publications were analyzed from the perspective of the App, User and Developer, that correspond to the main elements in a MSECO. The data found showed that most of the models present limitations for real application in the context of the industry. From this analysis, this work complements the AppEco simulation model. This model has been thoroughly evaluated with a set of 100 real mobile applications on the Android platform. In this context, supported by the expanded model, the MSECO SIMU tool was developed, bringing this theoretical model closer to practical application by Apps developers. / Em um Ecossistema de Software Móvel (em inglês, Mobile Software ECOsystem - MSECO), fabricantes fornecem uma plataforma para desenvolvedores criarem aplicações móveis ( Apps ) e as disponibilizá-la para consumo de seus usuários, possibilitando assim a oferta de um número maior de soluções e serviços. Uma diversidade de fatores pode influenciar no sucesso e desempenho de uma App ao longo do tempo, dificultando a construção de boas soluções nesse cenário de incerteza. Nessa problemática, o uso de simulação mostra-se como uma importante ferramenta para apoio à tomada de decisão, experimentando de forma controlada diferentes cenários em um MSECO e minimizando risco na busca pela criação de uma App popular. Essa pesquisa realizou um Mapeamento Sistemático da Literatura onde foram identificados 19 trabalhos relacionados ao tema de simulação de MSECO. Eles foram analisados sob a perspectiva da App , do Usuário e do Desenvolvedor, que correspondem aos principais elementos em um MSECO. Os dados encontrados mostraram que a maioria dos modelos apresenta limitações para aplicação real no contexto da indústria. A partir desta análise, este trabalho complementa o modelo de simulação AppEco. Este modelo foi avaliado minuciosamente com um conjunto de 100 aplicações móveis reais na plataforma Android de diferentes categorias. Como resultado, o modelo foi ampliado e a ferramenta MSECO SIMU foi desenvolvida, permitindo a aproximação de um modelo teórico ao uso prático por desenvolvedores de Apps.

Context: Due to rapid increase in the population of elderly people, sharing healthcare information has become an essential requirement for the development of e-health system. By conducting a research in e-health and cloud computing we have explored the advantages and disadvantages of sharing healthcare information for elderly people through cloud computing. Objectives: The main purpose of this research is to investigate the suitability of cloud computing to share healthcare information. The study is conducted by exploring the advantages and disadvantages of cloud computing for e-Health systems. Investigating a suitable cloud computing platform is also one of the objectives of this research. Methods: In order to identify and get deeper understanding of these issues, we have performed literature review of E-health, EHI and Cloud Computing technologies and we have develop a prototype application as experiment. Results: Based on the finding of literature review, we came to know that E-health was huge field. It needs a huge infrastructure to establish. The healthcare information in e-health requires quick and easy sharing. In EHI research, we defined EHI and find reasons for sharing elderly healthcare information. At cloud computing research, we knew the concept of cloud computing and found out advantages and disadvantages of implementing e-health in cloud computing. From literature review, we developed sharing application which was used to share EHI in cloud computing. In experiment, we proved our supposition and discussed advantages and disadvantages of sharing EHI in cloud computing by using Google App Engine (GAE). Conclusions: We conclude that cloud computing meets the requirements of sharing EHI, but it also has some limitations due to its architecture and network condition. In this research we have identified further research area that can help in enhancing security and privacy in cloud environment.

Syftet med arbetet var att utveckla en programvara (app) för patienter med kroniskt obstruktiv lungsjukdom (KOL) för att de skall kunna lära känna sin sjukdom bättre och därmed förbättra sin livsstil för att kunna bromsa försämringen av sjukdomen. Åldersgruppen som appen vänder sig till är mellan 40-80 år och för att de äldre skall ta till sig den nya tekniken med smartphones bör appen ha en enkel design. Den här gruppen patienter har kanske inte så stor teknikvana med datorer så det är också en anledning att ha en app som är lätt att använda.Utvecklingsprocessen av appen har gjorts i flera steg. Först formulerades en rad frågor om hur appen skulle fungera. Därefter formulerades frågor som patienten skulle svara på. Den första versionen av appen var en Powerpointdesign som därefter utvecklades i olika steg till en färdig Android app. Flera patienter fick testa appen under utvecklingens gång och även svara på ett frågeformulär om deras upplevelse av att använda appen. Patienterna gav förslag på ändringar och uttryckte behov av utveckling. Slutversionen av appen blev omtyckt av testgruppen och några förslag har även lämnats till vidare utveckling.

Entrepreneurship educations in developing countries have not yet been able to take advantage of digital tools. The Ugandian non-profit YoungDrive has 60 coaches teaching entrepreneurship to 12 000 youth in rural areas. The coaches have a problem during and after their education with assessing and improving their abilities to learn and teach entrepreneurship. The purpose of this study was to investigate how an app can be designed to address this issue. Methods within service design, agile development and interaction design has been used and combined to construct and analyse interviews, workshops, question sets, and app tests with the coaches in Uganda and Zambia. In total, three months were spent testing and iterating on low-detailed and high-detailed prototypes. The result is a launched hybrid app for Android, iOS and web. A formative test shows coaches are more reliably correct using an improved design of multiple-choice questions than a standard multiple-choice design. Interviews shows the coaches has become more aware of what they know and do not know, and feels more confidence before their youth lesson with an increased quiz result. Further research should evaluate that the actual quality of the youth lesson improves. Increasingly well-constructed multiple-choice questions with thoughtful feedback could stimulate creativity and problem-solving, deemed important by entrepreneurship education research. After overcoming usability issues, the final app could reach both low and high-order learning objectives within entrepreneurship. The app did seemingly improve the quality of entrepreneurship education for the coaches in this specific developing world context. Further research should also investigate the design and implications of a digital-only entrepreneurship education for the coaches, having in mind that the teacher is believed the main factor of entrepreneurship education. As of now, the app is an effective compliment and assistance to the physical training.

Ett av de områden där utvecklingen idag går som snabbast är IT och de senaste åren har det varit mobilapplikationsutveckling som dominerat. Allt fler skaffar smarta mobiler och antalet applikationer (appar) till dessa ökar konstant. Med en internetuppkoppling finns det idag ytterst få begränsningar för vad du kan göra med en smartphone. I takt med att antalet internetuppkopplade enheter eskalerar, ökar också antalet illasinnade individer vilka ser Internet som sin främsta inkomstkälla. I den här kandidatuppsatsen intervjuades företagsrepresentanter angående hur företagen tänker kring implementationen av säkerhet vid utveckling av mobilapplikationer. Studien bygger på en empirisk såväl som en teoretisk del. Det som framkommit under arbetet med uppsatsen är bland annat att företagen är väl medvetna om säkerhetsriskerna. De gör ingen större skillnad på utvecklingen av traditionella skrivbordsapplikationer och mobilapplikationer. Det är heller ingen stor skillnad mellan dessa säkerhetsmässigt.

Ett företag som bedriver hunduppfödning når många av dess kunder via Internet och befintliga webbsida. Detta examensarbete syftade till att via en deduktiv metod ta fram en prototyp baserat på studier inom mobil designprocess, mobilt användbarhet samt en granskning av relaterade mobila hemsidor som redan finns på marknaden. Frågor gällande rätt mängd information på mobilhemsidan samt passande designmönster låg i fokus för att lösningen skulle vara användarvänligt men samtidigt innehållsmässigt tillfredsställande. En prototyp skapades och testades via kvalitativa intervjuer. Då antaganden gällande prototypens design till viss del bekräftades uppkom även, via användarnas feedback, behov av att göra vissa ändringar. Resultatet av rapporten belyste vikten av hur struktur och siduppbyggnad måste brytas ned från en webbsida och återskapas för att passa i ett mobilt användningsområde. Samt hur användandet av korrekta designmönster och rätt mängd innehåll, krävdes för att skapa en snabb, lättanvänd och innehållsmässigt korrekt sida för användning i ett mobilt sammanhang.

Spotify wants to explore the possibilities of social gaming within their desktop client. Thanks to their Spotify Apps API it is possible to build applications that integrate with the Spotify library while using modern web technologies. This thesis work consists of exploring what is possible using the Spotify App API and the most modern web technologies available. The main theme and goal of the Spotify App is to engage users in a social context. Creating a quiz application, which users can play along with using their smartphones, does this. This is targeted towards people being in the same room, sharing the experience. There is also a focus on usability and both group discussions and think-aloud interviews have been conducted regarding the development and design of the product.

The iPhone has become a top selling smartphone since its launch in 2007 and has along with its iOS (Apple's mobile operating system) overtaken many popular and established mobile phone brands in the ratings. Some competitors have not been able to provide a competing smartphone while others have grouped together to withstand the Apple onslaught. There are probably quite a few reasons why the iPhone has become such a success, and one could likely write a report solely about those reasons. I will focus on one of them in this study, maybe one of the most important reasons: the iPhone came with a revolutionizing user interface. I have studied iOS applications and their user interface components along with related research in order to try and find out what exactly makes it so attractive and also to uncover any flaws I might stumble across along the way. In order to answer this, and to gain a better insight into the iOS, I have developed an iPhone application from scratch covering all of the basic functionality usually found in any other iPhone application. The results will show that most of it seems to relate with Apple enforcing very strict rules and guidelines, along with limitations placed on the developer and the process as a whole. This strict process ends with Apple evaluators performing a review of the finished product, using their guidelines as heuristics. These guidelines will be proven to have scientific credibility, and the controlled development process will be a key to defining the iOS success.
