This thesis deals with the exploration of different interaction possibilities for three-dimensional, virtual objects in a real environment. The focus lies especially on interaction possibilities from new AR-technologies. A playful prototype of an application for Microsofts HoloLens will be designed and implemented. The prototype consists of three parts. The first part is the scan-process of the real environment of the user. In the second part the user can augment the real environment with three-dimensional, virtual objects. In the third part the user is supposed to navigate a virtual avatar through the real environment. The interaction possibilities of the HoloLens like Gaze, Gesture and VoiceInput will be evaluated in the following categories menu navigation, positioning of three-dimensional objects in a real environment and controlling an avatar.
