The invention relates to a control device of a capacitive touch surface capable of detecting the position or movement of at least one finger or a control stylus of a user in the proximity of the capacitive touch surface. The device includes a three-dimensional control member secured to the capacitive touch surface and provided with an electrically insulating body having a lower surface facing the capacitive touch surface and a three-dimensional surface intended to be touched or scanned by at least one finger or a stylus of a user. The three-dimensional control member is provided with a plurality of electrical conductors separated in pairs by an electrically insulating space and configured to exchange electrical charges with the capacitive touch surface when a user touches or swipes the three-dimensional surface, such that a user can interact with the capacitive touch surface via the three-dimensional control member.

A system includes sensor-actuator units fixed onto a plate to be actuated according to at least one predetermined vibratory mode, each sensor-actuator unit having an electromechanical actuator and a deformation or vibratory speed sensor, wherein the electromechanical actuator and the sensor are colocated on the surface, that is to say that the measurement by the sensor is performed in immediate proximity to the electromechanical actuator, this proximity being such that the actuator and the sensor can respectively actuate and measure the same predetermined vibratory mode.
