Schematic representation of the assessment scenario. Three individuals wearing HoloLenses were participating in the assessment. The assessor and examinee (black) both shared a stereoscopic view (double dashed line) of the holographic three‐dimensional (3D) model of the lower leg including user interface. A passive observer (gray), also wearing a HoloLens, shared the same view but monoscopically (single dashed line) and recorded the session on video. All devices were synchronized through a local Wi‐Fi network, and all devices stored a logfile with timed registrations of operations and confirmed answers.
