摘要：A telecommunication device has: a projection unit for projecting image
information on a projection surface situated outside the telecommunications device, theimage information being projected onto the projection surface (i) with the aid of at leastone optical element in a projection beam path for sequentially constructing an image,and (ii) for momentarily spatially limiting the projection relative to the total area of theimage information on the projection surface; and a detection unit. During projection amovement of the projection surface, e.g., a displacement or a rotation, takes placerelative to the projection unit. The detection unit detects the movement of the projectionsurface with the aid of a reflection signal passing along a detection beam path, theprojection beam path and the detection beam path coinciding at least in the area of theat least one optical element.
