d) 3D Trajectory guidance (a) Patient anchoring (b) Tool anchoring (c) Surgeon anchoring (e) 2D Crosshair guidance Figure 1: Overview of three spatial anchoring strategies compared in this study across two AR guidance techniques. (a) guidance anchored to the Patient's knee. (b) guidance anchored to the surgical Tool. (c) guidance anchored to the Surgeon's head.
