Thesis describes programming of 3D applications, mainly games, on Windows Phone 7 platform and lightly compares this approach with Silverlight platform. It also describes XNA framework in detail and programming plane simulators problems. In the second part of this thesis, reader can find complete description of implementation of a simple airplane simulation for Windows Phone 7 platform, which is based on the XNA framework. The game consists of implementation of terrain, sky, plane, scene and also of physics and the principle of the game.

The scope of this thesis is to design tools to support business processes on mobile platforms. The work deals with both the Enterprise Resource Planning systems issue, as well as the database synchronization and the possibilities of secure data transmission between the mobile device and the server. The work also includes familiarization with the most widely used mobile platforms and tools for multi-platform application development. The last part of the thesis comprises a model of an application meant to support business processes on mobile devices, including a description of its implementation, used tools and testing.

The aim of this project is to design an application for mobile platform which can insert virtual objects to camera shots without disturbing the scene. The application is implemented on Windows 8.1 and Windows Phone 8.1 platforms. The scene rendering is done in DirectX with C++ programming language and the user interface is created in XAML. This text describes the relevant fundamentals of augmented reality and the selected platform and it describes advanced programming techniques such as asynchronous resources loading or advanced post processing rendering techniques. The result of this project is a mobile application for inserting a virtual object with its shadow to camera shot. It is possible to set some aspects of the light and take a picture with the virtual object in high resolution.

Responsive design is a common expression at the web today. This thesis was about learning about responsive web design in order to apply it to Windows 8 applications created in C# and XAML. The purpose of this thesis was to learn if responsive design can be used in such applications. This was done by first learning about responsive design through a literature study about responsive web design and then specifying responsive application design. How responsive design can be used in applications was found through research and creation of an example application. No literature was found about responsive design for Windows 8 applications in C# and XAML and therefore most of the results came from own ideas and partly solutions found on different forums. The thesis was performed at Infor in Kista. The example application was a social application which was connected to a social web service developed by Infor. Responsive web design is a technique used for making webpages adapt to the size and resolution of the viewport. This is done by creating a structured, fluid layout by using a flexible grid and flexible images. Media queries are used to set up different states for presenting the page in different ways for different sizes and resolutions of the viewport. In the different states parts of the content can for example be hidden or styled. The number of columns of information can also be set to adapt to make the page easier to view. Responsive design for applications should make the layout of the application adapt to fit the application window of the device used depending on its resolution. One way to specify a responsive design for Windows 8 applications could be to create only one application which could be used on all different Windows 8 platforms, such as phones, tablets and computers. It is probably not possible today to create this one application for different Windows 8 platforms. Another way of specifying responsive design for application is to create a responsive user interface which could be shared and used in the different Windows 8 applications. The latter was the chosen definition for this thesis. The scope of this thesis was limited to only research for responsive design in Windows Store apps and Windows Phone 8 applications. Windows Phone 8 applications are applications used on smartphones with Windows Phone 8 as operating system while Windows Store applications are used on computers with Windows 8 as operating system. Other Windows 8 devices were not included in this thesis. The final conclusion of this thesis was that although it is complicated to use responsive application design it can be used for most of the user interface. A responsive user interface for the applications can be created separately, but some parts of the application pages cannot be shared between the different platforms. This results in a mostly responsive sharable user interface.
