Abstract

A touch-sensitive surface is provided on an operator control device that includes a way to detect a force applied by a user to at least one area of the touch-sensitive surface. An actuator generates haptic feedback to the user when the force applied exceeds a threshold value. An evaluation unit of the operator control device determines a time-related gradient of the force and changes the threshold value of the force according to the time-related gradient.
