Abstract
An instrument is mounted on a motorized positioning mechanism for providing a contactless guidance of the instrument. A transmitting unit and a receiving unit are arranged in a defined relative position to an operator and the instrument so that an evaluation unit positions the instrument via corresponding control signals with the aid of the registered signals of the receiving unit. A preferred application is the contactless guidance of a surgical microscope which tracks the head movements of the surgeon.
