A method for contactlessly interacting with a module, the module having a first submodule and a second submodule; in a first method step, the first submodule producing a primary beam; in a second method step, the second submodule inducing a scanning movement of the primary beam to allow image information to be projected into a projection area; in a third method step, a control command executed by an object being recognized by the module; the control command relating to contactlessly interacting with the module; in the third method step, the module detecting a geometric shape of the object.
