Preference for detail in 3D anatomical models amongst professionals and laypersons

This study investigated preference of both professionals and laypersons for different levels of detail in anatomical 3D models. Staff and students working with anatomical material at the University of Dundee, along with lay members of the public, were asked to give their preference regarding six 3D digital anatomy models. Three models showed the external anatomy of the human heart, and three showed the internal anatomy, each at varying levels of detail: low detail, medium detail, and high detail. Thirty-six participants took part in the study. Results were compared by overall preference as well as specifically in terms of the model's clarity and aesthetics. Results showed the majority of participants preferred the 'high detail' model overall as well as in terms of aesthetics, however the results for the model's clarity were more varied.
