In this thesis we describe the development of an application that combines the principles of motion detection with virtual reality. Motion detection was carried out with the help of Microsoft's Kinect and we used Google's Cardboard to achieve the virtual reality experience. To this end, we have set up a system that has processed and converted Kinect data into a form that was suitable for operation in the Unity environment. We ultimately developed the application in two separate games. The first one is intended for a single player who, in virtual reality, is walking above the abyss. The second game is called "Rokoborba" and is intended for two players who are placed in a boxing ring, where they try to fight each other. To better understand the problem, we studied the theoretical background of the selected technologies. The first part of the thesis describes the Kinect and virtual reality technologies, followed by an explanation of the tools and environments that we needed to develop the application. In the second part of the thesis, we describe the development of the application. Each step of development is explained in more detail. We describe how does the application work and list possible improvements to the program. At the end we present the results of testing the applicatons.
