1. A method of operating a surgical system comprising a navigation system including a localizer including a field-of-view and a tracker, and one or more controllers coupled to the navigation system, wherein the one or more controllers include a processor, the processor implementing a virtual boundary generator, a collision detector, and a feedback generator, the method comprising:
detecting, with navigation system, the tracker within the field-of-view of the localizer by establishing a line-of-sight relationship between the tracker and the localizer;
generating, with the virtual boundary generator, a virtual line-of-sight boundary based on the line-of-sight relationship;
associating, with the one or more controllers, a virtual object with a physical object;
detecting, with the collision detector, a virtual collision between the virtual object and the virtual line-of-sight boundary; and
enabling, with the feedback generator, a response based on detecting the virtual collision.
