Navigation systems and methods for reducing tracking interruptions during a surgical procedure

EDITORIAL NOTE APPLICATION NUMBER - 2022200731 Please note: Abstract page 50 should be numbered 56. A method of operating a system comprising a manipulator configured to support a surgical tool, a navigation system comprising a localizer including a field-of view and a tracker, and one or more controllers coupled to the manipulator and the navigation system, the method comprising the one or more controllers: detecting the tracker within the field-of-view of the localizer by establishing a line-of-sight relationship between the tracker and the localizer; generating a virtual line-of-sight boundary based on the line-of-sight relationship; associating a virtual object with one or more of the manipulator or the surgical tool; determining that a movement of one or more of the manipulator or the surgical tool causes a virtual collision between the virtual object and the virtual line-of-sight boundary; and enabling a response based on an outcome of determining that the movement causes the virtual collision.
