1. A method of operating one or more output devices for a motor vehicle in a non-contact control, the method comprising:
providing one or more sensors and the one or more output devices, the one or more output devices comprising at least one of a plurality of displays, display regions, projectors, or projection regions;
detecting, using the one or more sensors, two or more inputs comprising:
i) a first input comprising an eye trajectory of a passenger;
ii) a second input comprising a proximity of a body part of the passenger relative to the one or more output devices and a trajectory of the body part relative to the one or more output devices,
wherein the body part is a head of the passenger or a torso of the passenger, and
wherein an intended field of view of the eye trajectory is verified based on the second input to prevent random eye movements from being classified as an input; and
iii) a third input comprising an affirmative non-contact hand gesture of the passenger, the third input displacing, from the at least one of a plurality of displays, display regions, projectors, or projection regions, a display element within the intended field of view of the eye position; and
controlling a power consumption of the one or more output devices based on the two or more inputs, controlling the power consumption comprising:
turning off or reducing power consumption of the one or more output devices; and
turning on or increasing power consumption of at least one audio output device after turning off or reducing power consumption of the one or more output devices.
