Many medical applications such as brain surgery or stimulation require the clinician to identify an internal target location. Mixed reality see-through displays that enable a holographic visualization of brain MRI superimposed on a subject’s head can help clinicians identify internal target locations but require tracking methods that keep the holographic brain MRI aligned with the subject’s head as they move. We present a method for marker-less tracking of a subject’s using a depth-sensing camera, which tracks facial features and sends location and rotation information to a see-through display to update the location in space of the MRI holograms.
