analyzing the current surgical step. Such systems can simplify the user interface

and thus lower the cognitive burden of the surgeon-user.

The types of prior-knowledge data that have been visualized in AR systems for

craniofacial, maxillofacial, and dental surgery are the tracked surgical tools used

(e.g., saws).

20.3.2.2 Visualization Processing

Perhaps due to the use of primarily vector objects, visualization processing of data

for these types of surgery is not typically described. When surface models have been

used, only transparency (Liévin and Keeve, 2001; Trevisan et al., 2006) and color

coding (Trevisan et al., 2006) have been noted as visualization techniques.
