Abstract Novel augmented reality headsets such as HoloLens can be used to overlay patient-specific virtual models of resection margins on the patient’s skin, providing surgeons with information not normally available in operating room. For this useful, wearing headset must able localise accurately. We measured error which users at different positions and distances from their eyes. Healthy volunteers aged 20–59 years ( n = 54) performed 81 exercises involving localisation a hexagon’s vertices overlaid monitor surface. Nine predefined three between hexagon users’ eyes (65, 85 105 cm) were set. found that, some model shortest distance (65 led larger errors than other (85 cm). Positional more 5 mm 1–5 margin 29.8% over 40% cases, respectively. Strong outliers also (e.g. shrinkage up 17.4 4.3% cases). The may result poor outcomes surgeries: e.g. incomplete tumour excision or inaccurate flap design, potentially lead recurrence failure, Reducing associated arm reach is necessary for suitable surgical purposes. In addition, training use these help minimise errors.
