1. A surgical system comprising:
an augmented reality (AR) headset configured to be worn by a user during a surgical procedure and including:
an AR transmitter configured to project light for an AR image;
a see-through display screen configured to combine the projected AR image and a real-world scene for viewing by the user, and
an opacity filter positioned between at least one of the user's eyes and the real-world scene when the see-through display screen is viewed by the user, wherein the opacity filter is configured to provide opaqueness to light from the real-world scene; and
AR headset controller configured to communicate with a navigation controller to receive navigation information from the navigation controller which provides guidance to the user during the surgical procedure on an anatomical structure, and configured to generate the AR image based on the navigation information for display on the see-through display screen;
wherein the opacity filter is configured with at least two horizontally extending bands extending over both eyes, each band extending across the entire width of the see-through display screen, wherein an upper one of the at least two horizontally extending bands has a lower light transmissivity than a lower one of the at least two horizontally extending bands;
wherein the augmented reality headset is operationally coupled to a robotic system having a robotic arm that is controllable based on hand gesture commands that is sensed by the augmented reality headset.
