AB  - This work examines spatial anchoring strategies to position augmented 
reality guidance during surgery. We consider three strategies: anchori
ng to the Patient, the surgical Tool, and the Surgeon’s head. These st
rategies were evaluated in a first experiment involving 24 non-profess
ional participants, using two guidance techniques: 3D Trajectory and 2
D Crosshair. For 3D Trajectory, Patient and Tool anchoring were more p
recise than Surgeon anchoring, and Patient anchoring was the most pref
erred. For 2D Crosshair, no significant effect of anchoring strategies
 on precision was observed. However, participants preferred Patient an
d Surgeon anchoring. A second experiment with 6 surgeons confirmed the
 first experiment’s results. For 3D trajectory, Tool anchoring proved 
more precise than Patient anchoring, despite surgeons’ preference for 
Patient anchoring. These findings contribute to empirical evidence for
 the design of surgical AR guidance, with potential applications for s
imilar, less critical tasks.
