Abstract
The invention relates to a method and a playback device for a two- and/or three-dimensional illustration, having at least one light source, at least one light modulation device, a display screen, and a tracking system for tracking a virtual viewer window of a viewer plane, in which at least one viewer is located. This tracking system has a position detection system for determining the eye positions of the at least one viewer in the viewer plane, a tracking device, and a control device for activating and controlling the tracking device, and is disposed between the light modulation device and the display screen. In order to track the viewer window along an optical axis of the playback device, a focal width on the image side of an optical system of the tracking device is constant.
