1. A method for controlling a man-machine-interface unit, wherein with respect to at least one user an initial status (e i ) before and a final status (e f ) after an action (a) taken place are essentially detected, and wherein data triples essentially representing said initial status (e i ), said final status (e f ) and said action (a) taken place are collected as learning samples (l), and wherein said learning samples (l) are used to at least derive and/or initialize a target action to be carried out so as to carry in each case said user from a given current status (e c ) to a given desired target status (e t ).
