Hand-made illustrations in scientific and technical textbooks commonly use internal and external labels or legends to establish co-referential relation between pictorial elements and textual expressions. By analyzing the most complex examples, we extracted several label layout styles and classified them. We propose a variety of real-time label layout algorithms that aim to produce nice and clean layouts. In order to achieve a frame-coherent label layout during user interactions, the algorithms consider layout decisions from previous frame. Moreover, several evaluation criteria to measure the quality of static as well as dynamic label layouts are presented.
