Abstract
A medical system has at least one projection surface onto which a projection unit projects of operating elements. The system is controlled by detecting movements of a hand, preferably a finger, of an operator on the projection surface. An optical detector acquires the position and/or the motion of the finger relative to the projection surface, and a control unit evaluates the output data of the detector in order to control the system.
