Interactive Techniques For Co-Registration Of Extended Reality And Surgical Navigation Systems

Abstract

Techniques for co-registration of extended reality and surgical navigation systems involve detection of a spatial relationship between a virtual registration object and a physical registration object (e.g., tool). The physical registration object is observed on, or through, the display of the head-mounted device (HMD). In one implementation, biomechanical control input (e.g., hand/finger or eye tracking) from the HMD user is sensed to command acquisition of the virtual registration object relative to the physical registration object. In another implementation, the virtual registration object is presented on the HMD display for alignment with the physical registration object. In some instances, a virtual guide object is presented on the HMD display to dynamically guide the user to align the physical and virtual registration objects.
