ABSTRACT:
In an operating device for a cooking system with a hob and an operating surface, at least one operating element with a contact detection function is positioned under the operating surface. The at least one operating element is implemented as a motion or movement sensor with a camera, which detects a movement or a contact point on the operating surface and determines a position and/or a position change of the contact point on the operating surface. In an operating method for activating an operating function an evaluation unit evaluates the position or the position change of the contact point.
