摘要：
A medical device is controlled as a function of a position of a control element projected onto a projection surface, wherein a geometric property of the projected control element is adjusted to the surface structure. The adjustment is accomplished by means of a transformation of projection data, the projection data corresponding to the control element that is to be projected. The optical projection of the control element is based on the transformed projection data. Such an adjustment and transformation are made possible by determining the surface structure of the projection surface. The control system has an image processor both for determining the surface structure and for transforming the projection data. The control system additionally has a projector for optically projecting the control element and a control unit for controlling the medical device based on the first position of the projected control element.
