Abstract: A virtual head-up display which is displayed to a user with a head-mounted display, wherein at least some elements of the HUD are displayed substantially stationary in respect of the head's coordinates at the edge of the user's field of vision, even if the head is moved is provided. A tracking device captures at least one hand and/or finger movement by the user as a gesture. The gesture is detected and processed as an interaction with at least one element of the HUD.

Direct interaction with the HUD by means of gestures represents a disruptive break with previous approaches to the implementation of a HUD for VR and AR applications.
