Abstract
The invention relates to a method for controlling a touch surface control device, including at least one step comprising the generation of sensory feedback corresponding to the detection of a pressure applied by a user on the touch surface, said sensory feedback comprising haptic feedback and acoustic feedback. The invention is characterized in that the generation of the acoustic feedback is initiated after the generation of the haptic feedback once a characteristic value of the haptic feedback has exceeded a pre-defined threshold. The invention also relates to an electric control device having a touch surface, characterized in that it includes means for implementing said method (1).
