"Using the motorized calibration rig as presented in the paper, we were also able to assess the dynamic latency when viewing augmentation graphics on a mobile target; spatial displacement due to latency was found to be in the range of 1.1-2.8 mm maximum, the disparity between the true object and its computed overlay represented latency of 0.1 s," published data indicated.

This automatic calibration method "is sufficient in terms of accuracy and time requirements for standard uses of optical see-through systems in a clinical environment," the researchers concluded.

Figl and coauthors published their study in IEEE Transactions on Medical Imaging (A fully automated calibration method for an optical see-through head-mounted operating microscope with variable zoom and focus. IEEE Trans Med Imaging, 2005;24(11):1492-1499).
