The invention relates to a 3D input device (1) for controlling the position of an object (8, 14) in space, comprising a manually operated 3D input element (3), at which input element control specifications in three spatial coordinates can be input, and a control dial (4), which generates an output signal dependent on the rotary angle when rotated. According to the invention, the 3D input device (1) comprises a control unit (21), which moves the object (8, 14) in space depending on the rotary movement executed at the control dial (4).
