Mobile internet represents a major new trend in communication technologies use and consumption, but few evidence exists that confirms claims of novelty and social change in association with this technology use. This paper characterizes the use of mobile internet in a southern European country and associated patterns of use, focusing both on users’ profiles, forms of access, motivations to use and most popular activities undertaken via this technology, from a diffusion of innovations and social adoption of technologies perspectives, and tries to compare mobile it with fixed access to the internet in order to validate possible transformations that point to new social configurations. We seek to understand the way stakeholders perceive and characterize the European context of mobile internet. The depicted study involved a qualitative stage consisting of a set of interviews with mobile communications industry representatives and market research community in the country. These interviews were analysed in Nvivo, leading to the following eleven main categories that are explored throughout the paper: smartphones in Europe, mobile internet in Europe, users profiles, obstacles to the spread, forms of access, forms of use, motivations to use mobile internet...

Mestrado em Gestão de Empresas; This master’s thesis is about Acceptance and Attitudes towards Mobile Promotions in Young Portuguese Adults. The research framework of this study intended to test if past mobile phone usage, characteristics of the mobile promotions messages and the past experience with mobile promotions would influence the attitude towards mobile promotions. Furthermore, it was also tested if this attitude influences brand engagement and behavioral intention. Finally it was verified if different mobile users’ profiles had different responses regarding attitudes, brand engagement and behavioral intention. For research purposes it was applied an online survey to a non-representative sample of Portuguese’s young adults, aged between 18 to 29 years old that had received at least one promotional message in the last 6 months. From April 13th to 23rd of 2012 were collected 513 valid surveys. From this research it was possible to conclude that the past mobile phone usage does not influence the attitude that people have towards mobile promotions. On the contrary, the characteristics of mobile promotions and the past experience with it influence the attitude towards it in a moderate and positive way. Usefulness is the factor that influences the most. And the majority of the respondents do not consider that had a good past experience with mobile promotions. Attitudes towards mobile promotions have a strong influence in brand engagement and behavioral intention of using the promotions. Finally...

It was just a few years ago when I bought my first smartphone. And now, (almost) all of my friends possess at least one of these powerful devices. International Data Corporation (IDC) reports that smartphone sales showed strong growth worldwide in 2011, with 491.4 million units sold – up to 61.3 percent from 2010. Furthermore, IDC predicts that 686 million smartphones will be sold in 2012, 38.4 percent of all handsets shipped. Silently, we are becoming part of a big mobile smartphone network, and it is amazing how the perception of the world is changing thanks to these small devices. If many years ago the birth of Internet enabled the possibility to be online, smartphones nowadays allow to be online all the time. Today we use smartphones to do many of the tasks we used to do on desktops, and many new ones. We browse the Internet, watch videos, upload data on social networks, use online banking, find our way by using GPS and online maps, and communicate in revolutionary ways. Along with these benefits, these fancy and exciting devices brought many challenges to the research area of mobile and distributed systems. One of the first problems that captured our attention was the study of the network that potentially could be created by interconnecting all the smartphones together. Typically...

This study intends to increase understanding of how different types of mobile money services have developed in different environments. For this purpose, two countries were selected, the Republic of Korea and Uganda. From these study cases, some conclusions emerge. The development of mobile banking services can appear at different stages of financial sector development, but it requires a vibrant and competitive telecommunications sector. The regulatory environment does not need to be very sophisticated for the mobile industry to emerge. However, some elements appear to be important. The legal framework should allow (or at least not explicitly forbid) nonbank financial institutions to issue money and use banking agents or correspondents. To ensure wider use of the service by the population, it is important to educate the population on the benefits of mobile money services.

With the cost of mobile phones decreasing steadily, what was once considered a luxury good is now more commonly considered a necessity by many Kenyans, including those at the economic base of the pyramid (BoP). iHub research and research solutions Africa conducted a 6-month study in order to increase the understanding of actual usage of mobile services, products, and applications at the BoP and to understand their potential for economic and social empowerment. The study covered urban and rural areas of 6 districts in Kenya. Its findings are not nationally representative, but comparisons with representative surveys show no significant differences for key indicators, such as phone possession. The added value of the study at hand lies in the qualitative insights on choices, lifestyles, habits and mobile phone usage patterns used among phone owners at the BoP, as well as its focus on add-on services ranging from phone applications to various Internet tools. The overall objective of the study was to provide a thorough and fact-based understanding of the current and potential future demand and usage patterns of the mobile devices by the BoP in Kenya.

Mobile phones are the primary means of accessing information or communicating for those who live at the base of the pyramid (BoP). It is likely that the mobile phone will therefore also be the preferred medium to provide value-added services to those at the BoP, whether they are private users or informal businesses, for the foreseeable future. Although the prepaid mobile model has brought voice and text services to this group, sustainable, replicable models for enhanced services, products and applications are far more limited. The purpose of the study is to investigate the demand for mobile applications, services and products, with a view to increasing economic opportunities and improving well-being for users at the BoP. The key objectives of the study are the following: i) to increase understanding of the actual usage of mobile services, products and applications at the BoP, and to understand their potential for economic and social empowerment; ii) to identify scalable examples of services, products and applications at the concept...

The dynamic growth of mobile communications technology is creating opportunities for economic growth, social empowerment, and grassroots innovation in developing countries. One of the areas with the greatest potential impact is in the contribution that mobile applications can make to agricultural and rural development (ARD), by providing access to information, markets, and services to millions of rural inhabitants. For both agricultural supply and demand, mobile phones can reduce waste, make delivery more efficient, and forge closer links between farmers and consumers. This report provides policymakers and development practitioners with a guide that facilitates the development and deployment of mobile applications for ARD. It also informs their understanding of the key drivers for promoting such applications and services in their countries. Using James Moore’s (1996) revised definition of ecosystems: economic communities based on interacting organizations and individuals the report identifies a wide range of players in the ecosystem for m-ARD apps...

This dissertation addresses the use of RGB-D images for six important tasks of mobile robots: face detection, face tracking, face pose estimation, face recognition, person de- tection and person tracking. These topics have widely been researched in recent years because they provide mobile robots with abilities necessary to communicate with humans in natural ways. The RGB-D images from a Microsoft Kinect cameras are expected to play an important role in improving both accuracy and computational costs of the proposed algorithms for mobile robots. We contribute some applications of the Microsoft Kinect camera for mobile robots and show their effectiveness by doing realistic experiments on our mobile robots. An important component for mobile robots to interact with humans in a natural way is real time multiple face detection. Various face detection algorithms for mobile robots have been proposed; however, almost all of them have not yet met the requirements of accuracy and speed to run in real time on a robot platform. In the scope of our re- search, we have developed a method of combining color and depth images provided by a Kinect camera and navigation information for face detection on mobile robots. We demonstrate several experiments with challenging datasets. Our results show that this method improves the accuracy and computational costs...

The use of mobile devices has become an integral part of our life today. Both on personal as well as business fronts, mobile devices have become a key mechanism for us to stay connected to the outside world. Military depends on this technology for a number of mission critical applications including operations tasking and commands and control. In the civilian world, mobile devices have become indispensable for business as well as personal communication. Mobile alerts – the notification of information or events via user’s mobile device – is a critical component to support the real-time connectivity needs of both military and civilians.

The mobile revolution has transformed the lives of Kenyans, providing not just communications but also basic financial access in the form of phone-based money transfer and storage, led by the M-PESA system introduced in 2007. Currently, 93 percent of Kenyans are mobile phone users and 73 percent are mobile money customers. Additionally, 23 percent use mobile money at least once a day. New potential for mobile money has come with the rise of interest-earning bank-integrated mobile savings systems, beginning with the launch of the M-KESHO system in March 2010. The authors examine the mobile savings phenomenon, using data collected in a special survey in late 2010. They show that the usage of bank-integrated mobile savings systems like M-KESHO remains limited and largely restricted to better-off Kenyans. However, what the authors term "basic mobile savings" -- the use of simple mobile money systems as a repository for funds -- is widespread, including among those who are otherwise unlikely to have any savings. Holding other characteristics constant...

While the growth of mobile communications in developing countries has been phenomenal, using mobile phones and applications to meet human and economic development goals is not widespread, for they have not proven acceptable or desirable to the locality into which they are introduced. Therefore, it is deduced that technical know-how and entrepreneurial acumen must be complemented by sociocultural understanding. InfoDev's Mobile Use at the Base of the Pyramid program seeks to contribute to this agenda through on-the-ground studies in developing markets. The first phase of this program supported both qualitative and quantitative research on mobile usage by low-income populations in Kenya and South Africa. This report documents the findings of this program.

There are more than 5.6 billion mobile phone users worldwide, making mobile phones more common than PCs. Mobile technology is a modern phenomenon with a great impact on industries and our society. Mobile phones began as very limited devices that provided only voice services. Today, these devices also provide a myriad of data services that allow us to browse the Internet, send text messages, check emails, watch movies, listen to music, take pictures, record videos, play video games and read documents. Mobile can also be used for payments, thus adopted by merchants in such a way to provide a new way for their customers to make their purchases. Different systems and business models have been developed for enabling Mobile Payments such as "Proximity" systems based on NFC technology and "Remote" systems that use the Mobile Operator's network and mostly widely adopted technologies such as SMS, WAP and Mobile Internet. Mobile remote payment systems are one of the most popular technologies for transactions today, especially across the media and online industries. Prior research mostly focuses on technology innovation or consumer-centric view while there is still less knowledge related to supply-side perspective and merchant attitude towards adoption of Mobile Payments. Literature is even more scarce when it comes to understanding the merchant adoption of specific Mobile Payment Systems such as "Remote Payment" systems based on carrier billing technologies.

Our increasing reliance on mobile devices has given rise to a new class of software applications (i.e., mobile apps). Tens of thousands of developers have developed hundreds of thousands of mobile apps that are available across multiple platforms. These apps are used by millions of people around the world every day. However, most software engineering research has been performed on large desktop or server applications. We believe that research efforts must begin to examine mobile apps. Mobile apps are rapidly growing, yet they differ from traditionally-studied desktop/server applications. In this thesis, we examine such apps by performing three quantitative studies. First, we study differences in the size of the code bases and development teams of desktop/server applications and mobile apps. We then study differences in the code, dependency and churn properties of mobile apps from two different mobile platforms. Finally, we study the impact of size, coupling, cohesion and code reuse on the quality of mobile apps. Some of the most notable findings are that mobile apps are much smaller than traditionally-studied desktop/server applications and that most mobile apps tend to be developed by only one or two developers. Mobile app developers tend to rely heavily on functionality provided by the underlying mobile platform through platform-specific APIs. We find that Android app developers tend to rely on the Android platform more than BlackBerry app developers rely on the BlackBerry platform. We also find that defects in Android apps tend to be concentrated in a small number of files and that files that depend on the Android platform tend to have more defects. Our results indicate that major differences exist between mobile apps and traditionally-studied desktop/server applications. However...

Mobile service provisioning is intended to serve interoperable functionality from mobile devices over the network. The mobile service paradigm shifts the role of mobile devices from consumers to providers, opening up new opportunities for a multitude of collaborative services and applications ranging from sharing personal information to collaborative participatory sensing. Although many basic principles of the standard Web service approach continue to apply, the inherent limitations of mobile devices and broadband wireless access render the deployment of standard architectures in mobile environments inefficient. This research introduces two concepts that revolutionize mobile service provisioning: personal and cloud-assisted service provisioning. Personal services are intended to offer a range of user-centric data services to a limited set of consumers that are explicitly authorized by the user providing the service. Personal services facilitate prevailing trends such as social networking and mobile healthcare services, without compromising personal privacy. Cloud-assisted service provisioning bridges the gap between limited resources of mobile devices and increasing resource demands of mobile applications. This approach provides reliable and efficient mobile services...

A evolução dos dispositivos móveis e a mudança de paradigma educacional, permitiu o surgimento de um novo conceito no processo de ensino e aprendizagem, o mobile learning. O mobile learning pode ser visto como um conceito multidisciplinar, dependendo da perspetiva de cada autor, pois ainda não existe um consenso em relação à definição do conceito. No entanto, todos os autores concordam que o mobile learning consiste na aquisição de conhecimento ou competência através do uso de tecnologias móveis, em qualquer lugar e momento. A presente investigação, de natureza exploratória, pretendeu estudar a receptividade e predisposição dos estudantes e docentes do ensino superior para com a utilização do mobile learning, uma vez que o ensino superior parece ser o ambiente ideal para a realização deste estudo. Por um lado, devido à democratização dos dispositivos móveis, por outro, porque o Instituto Politécnico do Porto pretende vir a implementar um projeto de mobile learning, enquadrado no e- IPP. Deste modo, para a concretização desta investigação, foi realizada uma revisão bibliográfica exaustiva que serviu de base de sustentação para todo o trabalho...

Advances in mobile hardware and operating systems have made mobile a first-class development platform. Activities such as web browsing, casual game play, media playback, and document reading are now as common on mobile devices as on full-sized desktop systems. However, developers are still constrained by the inherent resource limitations of mobile devices. Unlike desktop systems, mobile devices must sacrifice performance to accomodate smaller form factors and battery-backed operation. Opportunistic offloading of computation from a mobile device to remote server infrastructure (i.e., "code offload") offers a promising way to overcome these constraints and to expand the set of applications

(i.e., "apps") that can run on devices.

Deciding to offload requires a careful consideration of the costs and benefits of a range of possible program partitions. This cost-benefit analysis depends on external factors, such as network conditions and the resources availability, as well as internal app properties, such as component dependencies, data representations, and code complexity. Thus, benefiting from offload requires some assistance from developers, but requiring developers to adopt arcane or unnatural programming models will hinder adoption of regardless of the potential benefits.

In this dissertation we characterize two frameworks that reduce the amount of developer effort required to improve the performance of mobile apps through code offload. The first...

NTT DoCoMo is Japan's biggest mobile service provider. They added extra value into cellular phone as "telephone", and contributed to the explosive spread of the mobile phone in Japan. They have still led Japan as a country with the world's largest mobile Internet. The mobile phone now changes our lifestyles or work styles, and has a great influence also on business. In 1997, NTT DoCoMo created the company vision towards the year 2010, "Mobile Frontier". It consists of five concepts, named "MAGIC", and indicates the mobile phone figure in the future as a whole. I regard it as a guideline of this paper, and examine the direction of mobile evolution by researching the following topics: the present situation, the issues needed to realize each concept, and the future. At first, I state the background of the mobile phone spread in Japan and the cultural aspects peculiar to Japan. After that, I examine the mobile evolution along with the five concepts. The objective of this paper is to refer to and understand the vision of a leading company in the telecommunication field, and consider mobile communications' influence and applications in the future. The goal is to expand knowledge in the present situation of the mobile phone and the trend towards future mobile...
