Abstract
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.
