Complete navigation example. Complete navigation, split into four sequential panels (a, b, c and d) for the sake of understanding. Panel (a) shows the whole picture, which obviously looks very jammed by the number of windows and window movements. Hence navigation was split into a sequence shown in the next three panels: panel b starts by depicting a classical scanning pattern, composed of multiple jumps between ROIs. Panel (c) shows the magnification change from the dotted window to the thick one. Finally, the expert uses this magnification for exploring the rest of virtual slide in panel (d).
