A method and an illumination arrangement for generating image effects in the interior of a motor vehicle or also outside the motor vehicle. To use existing installation space as efficiently as possible, light is radiated, in the form of at least a first optical reference wave field, onto a irradiation surface that is arranged laterally on an optical image storage device. In the optical image storage, which contains a holographic layer or a diffractive optical layer, the optical reference wave field is transformed into at least a first image wave field and is emitted on an emission side, at a first angular offset with respect to the irradiation surface.

Disclosed is an air imaging apparatus for a vehicle. The air imaging apparatus for vehicle being mounted in a vehicle, comprises: an image source configured for generating a graphic for display; and an imaging magnifier configured for magnifying the graphic generated by the image source and forming a real image in the air inside a vehicle. Further disclosed is a human-machine interactive in-vehicle assistance system, comprising the air imaging apparatus for vehicle as described above and a gesture recognition apparatus nearby the real image. With the enlarged image, the icons for displaying contents are also enlarged; as such, the gesture recognition apparatus can easily recognize which command icon is to be touched by the user's gesture. The gesture sliding distance is also correspondingly enlarged for the user's sliding gesture operation, which significantly lowers the requirement on the precision of the gesture recognition apparatus.
