Slide navigation patterns among pathologists with long experience of digital review

• Aims: In order to develop efficient digital pathologyworkstations, we studied the navigation patterns ofpathologists diagnosing whole-slide images. To gain abetter understanding of these patterns, we built aconceptual model based on observations. We alsodetermined whether or not new navigation patternshave emerged among pathologists with extensive digitalexperience.Methods and results: Five pathologists were asked todiagnose a set of four cases while thinking out loud.The navigation within the digital slides was recordedand divided into re-occurring navigation actions. Thepathologists reused the same type of actions, but theiroccurrence differed. The most common action was aslow panning that followed an edge structure orcovered an area systematically, which accounted for30.2% of all actions and had a median duration of7.2 s. Of all the actions, 49% were carried out withinthe navigation overview and 38% of the actionscould not have been performed with a conventionalmicroscope.Conclusions: The new navigation possibilities in thedigital workstation were used to a large extent. Thedivision of actions into different concepts can be usedto find and prioritize between existing user interfacedesigns as well as to understand the different navigationstyles used by different pathologists.
