AIMS
In order to develop efficient digital pathology workstations, we studied the navigation patterns of pathologists diagnosing whole-slide images. To gain a better understanding of these patterns, we built a conceptual model based on observations. We also determined whether new navigation patterns have emerged among pathologists with extensive digital experience.

METHODS AND RESULTS
Five pathologists were asked to diagnose a set of four cases while thinking out loud. The navigation within the digital slides was recorded and divided into reoccurring navigation actions. The pathologists reused the same type of actions, but their occurrence differed. The most common action was a slow panning that followed an edge structure or systematically covered an area, which accounted for 30.2% of all actions and had a median duration of 7.2s. Out of all actions, 49% of them were carried out within the navigation overview and 38% of the actions could not have been performed with a conventional microscope.

CONCLUSIONS
The new navigation possibilities in the digital workstation were used to a large extent. The division of actions into different concepts can be used to find and prioritize between existing user interface designs as well as to understand the different navigation styles used by different pathologists.
