The invention relates to a system and a method for user-specific intuitive and secure control of operational inputs in software components with operational surfaces. Various operational elements on a surface can be reached with varying ease for the input of data, or for carrying out a confirmation action, for example, an OK click with the mouse. It is made easier or more difficult for an operator to carry out an input. The above is achieved, whereby input means, for example, a mouse are either drawn towards, or withdrawn away from the corresponding input regions. Erroneous inputs are thus avoided.
