1. A method for enhanced surgical navigation comprising:
generating a 3D spatial map;
detecting a position of a surgical tool in the generated 3D spatial map;
detecting a location of an anatomy in the generated 3D spatial map;
measuring a distance between the detected position of the surgical tool in the generated 3D spatial map and the location of the anatomy in the 3D spatial map;
determining whether the measured distance between the detected position of the surgical tool in the generated 3D spatial map and the location of the anatomy in the generated 3D spatial map is greater than a threshold minimum distance;
displaying a first band in a first form on the 3D spatial map and in a user interface, the first band having an outer dimension corresponding to the threshold minimum distance, the first band being displayed around the surgical tool or the anatomy;
displaying a second band on the 3D spatial map and in the user interface, wherein the second band is displayed around the surgical tool or the anatomy and includes an outer dimension that is different from the outer dimension of the first band; and
generating a warning when it is determined that the measured distance between the detected position of the surgical tool in the generated 3D spatial map and the location of the anatomy in the generated 3D spatial map is equal to or not greater than the threshold minimum distance from the location of the anatomy in the generated 3D spatial map, wherein the warning is displaying the first band in a second form on the 3D spatial map and in the user interface, the displayed second form of the first band having an outer dimension equal to the outer dimension of the displayed first form of the first band, the second form of the first band being displayed around the surgical tool or the anatomy, wherein the outer dimension of the displayed second band does not change.
