“…For OST-HMD-based overlay, the HoloLens 1 was the most frequently mentioned device, followed by the HoloLens 2 and Magic Leap 1. Several groups reported successful guidance based on the OST-HMD camera and surface registration with markers [ 46 , 47 , 74 , 86 ] and point registration based on feature matching [ 48 , 50 , 87 , 99 ]. The final overlay strategy discussed is manual placement of virtual content; in this case it was up to either the surgeon [ 72 , 81 ] or a secondary user [ 55 , 74 ] to ensure comfortable placement of virtual content.…”

“…Challenges in perception of virtually augmented elements can be attributed to a number of factors, including incorrect IPD estimation [ 40 ], incorrect or unaccounted for per-user display calibration [ 33 , 97 ], display limitations due to vergence-accommodation [ 10 ], misregistration of virtual content due to failed registration [ 106 ], and limitations of depth understanding of virtually augmented content [ 107 ]. Perceptual limitations contributed to additional errors in the stability of calibration during ultrasound image-guided robot cervical pedicle screw placement [ 93 ], with navigation during total shoulder arthroscopy [ 99 ], and with marker-less tracking for guidance in head and neck carcinoma imaging [ 75 ].…”

“…This is particularly important as prior publications have described the use of a diversity of different non-standard custom phantoms and protocols, which were not verified or validated by a recognized consensus body standard, to determine the accuracy and precision of HMD-based surgical systems. [8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25] This is the first known study that systematically assesses the accuracy of a HMD optical tracking system using the FDA recognized ASTM-F2554-18 consensus standard. This internationally and FDA recognized standard, was specifically developed and designed to determine the accuracy and repeatability of tracking systems to locate individual points in real world space.…”

“…However, literature review of such systems reveals a wide range of mean registration errors ranging from .76 mm to 8.22 mm. [8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25] Moreover, these different accuracy and performance assessments have utilized a variety of non-standardized custom measurement protocols and reporting practices, which prevents direct intersystem comparisons and generalizability.…”
