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.
