The invention relates to a graphical user interface for controlling a virtual reality (VR) graphics system by means of interactions with a function selection that provides at least two functions, whereby the VR graphics system has a projection device for visualizing a virtual three-dimensional scene, and interactions with the VR graphics system ensue by using at least one interaction unit. Said interaction unit, while interacting with a sensor system for detecting a respective physical-spatial position and/or orientation of the interaction unit, serves to generate and transfer position data inside and/or to the VR graphics system. The inventive graphical user interface comprises, in particular, an interaction element, which is functionally and visually formed from at least two partial elements that each provide a mentioned function selection. These at least two partial elements are provided so that they can move relative to one another in a virtual-spatial manner by means of physical-spatial movement of the interaction unit, and a function selection ensues by means of the ensuing virtual-spatial movement of the at least two partial elements relative to one another.
