This bachelor thesis investigates the utilization of the Wii Balance Board in virtual reality applications. For the investigation a snowboard game is implemented, in which the virtual avatar can be controlled with the pressure sensors of the Wii Balance Board. The user should be able to move playfully and intuitively through the virtual environment by balancing his body. The immersiveness and the influence on motion sickness and cybersickness will be investigated. In Addition, the Wii Balance Board will be compared with the Xbox Controller. The aim of the work is to evaluate whether the Wii Balance Board is able to allow free movement in virtual environments and whether it is more advantageous to use it rather than a conventional controller. The results of the survey indicate that the Wii Balance Board has a positive influence on the immersivness of the game, despite better game results by using a conventional controller. The survey also reveals that the use of the Wii Balance Board is responsible for more motion-sickness/cybersickness cases.

Im Bereich der Computergraphik bilden die Nicht-Photorealistischen Renderingverfahren einen Schwerpunkt in der technischen und wissenschaftlichen Visualisierung, vor allem aber in den künstlerischen Bereichen. Verschiedene Kunststile, sowie Zeichenmaterialien und ihre Eigenschaften stellen unterschiedliche Herausforderungen dar. Eine dieser Herausforderungen ist hierbei die Simulation flüssiger Zeichenmittel. Diese Arbeit beschäftigt sich mit der Erstellung eines interaktiven Zeichensystems für ein flüssiges Zeichenmittel, der Aquarellmalerei. Für die Simulation wird eine raue Zeichengrundlage generiert, sowie die Fluid Simulation und das optische Farbverhalten der Aquarellmalerei implementiert.

This Bachelor thesis describes the conception, implementation and evaluation of a playful augmented reality application for mobile devices. Building on the ARCore SDK, the game pARcours was developed, where the player can place virtual objects in the real environment to build their own parcours. This must be flown through with a likewise virtual aircraft. The main focus in the implementation of the game was on the interaction with the virtual objects and the collision detection of these with real surfaces. Furthermore, various input methods for building the parcours and controlling the aircrafts were examined. In a final evaluation both the game and the various input methods could be evaluated, as well as ARCore with regard to the development of augmented reality applications.

Tracking is an integral part of many modern applications, especially in areas like autonomous systems and Augmented Reality. For performing tracking there are a wide array of approaches. One that has become a subject of research just recently is the utilization of Neural Networks. In the scope of this master thesis an application will be developed which uses such a Neural Network for the tracking process. This also requires the creation of training data as well as the creation and training of a Neural Network. Subsequently the usage of Neural Networks for tracking will be analyzed and evaluated. This includes several aspects. The quality of the tracking for different degrees of freedom will be checked as well as the the impact of the Neural Network on the applications performance. Additionally the amount of required training data is investigated, the influence of the network architecture and the importance of providing depth data as part of the networks input. This should provide an insight into how relevant this approach could be for its adoption in future products.

In order to plan the interior of a room, various programs for computers, smart phones or head-mounted displays are available. The transfer to the real environment is a difficult task. Therefore an augmented reality approach is developed to illustrate the planning in the real room. If several people want to contribute their ideas, conventional systems require to work on one device together. The aim of this master thesis is to design and develop a collaborative spatial planning application in augmented reality. The application is developed in Unity with ARCore and C#.
