This thesis addresses the issue of mobile banking and analyzes applications, which provides mobile banking services. Aim of this thesis is to compare individual applications and analyze different approaches of applications based on Java technologies. Structure of this thesis is divided into four main parts. First part describes composition of bank services. It defines traditional and direct banking and points out differences between both concepts. Then it tries to show the position of mobile banking within the hierarchy of the bank. Second part gives detailed information about mobile banking itself. There is a research of current mobile banking situation on Czech market in the third part. This research includes products comparison and assessment. The last part focuses on presenting principles and problems of development on mobile phones through Java and then it analyzes these Java solutions in practice. The main contribution of this thesis is to provide information for companies or banks that choose to implement their own new mobile banking solution. Then this thesis should serve as initial analysis, which defines key parts of banking applications and how they should be properly processed. It could help to create efficient and successful mobile banking solution.

Cette étude est fondée sur deux constats dans le domaine de la maintenance aéronautique : l’utilisation non systématique de la documentation de maintenance aéronautique (DMA) malgré la prescription légale et l’évolution technologique qui a entraîné l’introduction de l’utilisation de l’appareil à petit écran ou mobile pour la consultation et la recherche d’information pour la réalisation de la tâche de maintenance. L’objectif de cette étude est double : identifier les raisons de la sous utilisation de la DMA et contribuer à la conception d’une documentation de maintenance adaptée à la fois aux supports mobiles (PDA), à l’utilisateur et au contexte de la maintenance aéronautique. Des tests d’utilisabilité ont été menés et testaient l’hypothèse selon laquelle l’utilisation du petit écran a un effet négatif sur les performances des utilisateurs. Des observations et entretiens dans les centres de maintenance ainsi que des tests sur avion ont aussi été conduits pour évaluer la lisibilité de l’interface et la portabilité des appareils mobiles. Les résultats montrent que les raisons de la non utilisation de la documentation de maintenance sont principalement liées à la non adaptation de celle-ci aux utilisateurs et au contexte du métier, que l’utilisation du petit écran est envisageable aussi bien pour une application destinée aux petits écrans que pour celle destinée aux écrans standard. En outre, l’utilisation du petit écran ne détériore pas, d’une façon générale, les performances des utilisateurs et qu’elle est envisageable aussi bien chez les novices que chez les experts qui sont encore réticents mais n’y sont pas opposés. / Literature review shows that maintenance operators do not use the aircraft maintenance documentation (AMD) systematically despite the legal obligation. The aim of this study is to contribute to the identification of users’ difficulty about the use of the AMD and the designing of maintenance documentation well-adapted to mobile devices (PDA), to users and to aircraft maintenance context. Hypothesis consists on verifying the effect of the small screen use on users’ performances. According to the usability test results, the small screen use has no negative effect on the users’ (experts and novices) performances. Field studies in maintenance centers and on aircraft show that small screen use is suitable to novices and experts for small screen documentation consultation and also for standard screen documentation when consultation is limited. Some users, particularly experts, are hesitant about using small screen for information consultation. However, they are not against the use of such format if information display is improved. Results are not limited to small screen documentation issue, some parts (e.g. information display study to reduce user effort) could be generalised to information system for task support.

[pt] Hoje em dia, o uso de dispositivos móveis se tornou bastante popular e criou maneiras diferentes de interação com sua interface sensível ao toque. Aplicações de visualização científica possuem um potencial muito grande de desfrutar dessas novas formas de interação, contudo o poder de processamento dos dispositivos móveis ainda não é suficiente para renderizar e-ou tratar o grande volume de dados que esse tipo de aplicação requer. Propomos um framework, seguindo um modelo cliente-servidor, que permite a utilização de dispositivos móveis para visualização e manipulação colaborativa de aplicações de visualização científica. No papel de servidor, a aplicação científica faz uso de uma biblioteca para compactar e enviar as imagens renderizadas para os clientes e também para tratar os eventos recebidos. No papel de cliente, está um aplicativo multiplataforma (iOS-Android) rodando nos dispositivos móveis, que interpreta os gestos de toque e exibe as imagens recebidas via rede Wi-Fi. O mesmo aplicativo é capaz de conectar em qualquer servidor, pois constrói a interface baseada numa descrição em Lua que o servidor fornece. Por fim, o framework proposto é avaliado em dois aplicativos industriais: Geresim e 3DReplay. / [en] Nowadays, mobile devices have become very popular bringing new ways of interaction with their touch-based interface. Scientific visualization applications have a great potential to take advantage of this new kind of interaction, but the processing capabilities of mobile devices are still not enough to render or process the amount of data this type of application requires. We propose a framework, working as a client-server model, which allows the use of mobile devices to collaboratively visualize and manipulate scientific visualization applications. In the server role, the scientific application uses a library to compress and send rendered images to clients and also to process received events. In the client role, there is a multiplatform application (iOS-Android) running on mobile devices, which interpret touch gestures and show the images received through Wi-Fi network. The same application is able to connect in any server, since it builds its interface from a description in Lua language supplied by the server. Lastly, we evaluate the proposed framework with two industrial applications: Geresim e 3DReplay.

The master's thesis is focused on Java based solution of remote PC control using a mobile phone. Application is made up of client and server, which are communicating via Bluetooth interface. The client represents a mobile application (MIDlet) and commands sent to the server. Server, run on a computer (with any operating system), read these orders and evaluate their algorithms to control the PC. The issue of the draft text is divided into two units, each of them describes just one part of the application. The client describes its functionality. It is also fully examines the structure of mobile application programmed in Java ME, together with the most important methods of this code. Text dealing with the server part describes its activities as well as individual options utilization. It describes the structure of the server application which is programmed in Java SE. There are also a description of the most important methods of the Java SE code. This thesis gives the results of both components of the application that allow to remotely control the computer and especially the presentation. The application was properly debugged and tested, and form a functional multiplatform software.

This diploma thesis deals with the options of image processing on mobile platforms, especially on Android operating system, and their use in a driver drowsiness detection system. The introductory part analyses the influence of drowsiness on drivers, focusing chiefly on the microsleep, and describes the already existing driver drowsiness detection systems. The thesis proceeds by the description of possibilities of image processing on mobile platforms with the emphasis on Android operating system together with the OpenCV library, known from the desktop interface. This is followed by comparison of various options of library implementation on a mobile platform. The chapter on image processing describes the algorithms for the detection of objects in the image, usable for detection of face, eyes and their posture. The practical part implements the selected methods for the Android operating system. A referential application was created to provide an explanatory demonstration of these methods on a real device. The individual methods are compared on the basis of time consumption, error rate and other factors.
