Abstract
A method for reducing a light intensity of a projection device is provided which includes the following steps: projecting information in the form of a visual representation onto a total area; emitting a plurality of electromagnetic signals which are essentially imperceptible to an observer onto the total area, using the projection device; detecting objects situated in the light path between the projection device and the total area with the aid of the electromagnetic signals; and reducing the light intensity of the projection device as long as an object is detected in the light path.
