The integration of artificial haptics on flat surfaces is a usability requirement resulting from modern control devices based on capacitive touchscreens. In automotive applications, aspects like high signal to noise ratio of the feedback, mechanical grounded situation of the devices and general robustness in thermal and climatic conditions have to be considered. This paper presents an electromagnetic actuator module for active tactile feedback for automotive applications, allowing a homogenous and intense feedback on a surface of at least 100x60 mm². The package of the actuator is thin, guaranteeing easy product integration even in complex multimedia control units. The resulting challenges on parallel guidance, sensing capabilities and resulting performance are sketched and summarized into an outlook for the future application in a series production context.
