Abstract: A UI for a HMD system includes a HMD configured to be worn by a surgeon. A tracker is configured to track head gestures by the surgeon. A footswitch is configured to detect foot motion inputs by the surgeon. A computer couples to the HMD, the tracker, and the footswitch. A user interface includes the HMD, tracker, and footswitch. The use interface is configured to: provide to the computer the head gesture in association with the foot motion input, and display an image relating to a surgical procedure on the HMD. The computer is configured to: apply the head gesture received in association with the foot motion input to perform a first action on the HMD system when the HMD system is in a first system mode, and perform a second action on the HMD system when the HMD system is in a second system mode.

Abstract: A user interface for enabling and controlling functions of a surgical system, comprising: a foot-operated function switch configured to be switched to any one of multiple discrete states by the user's foot; a head tracker configured to track the user's head motions; and a processor coupled to the function switch and head tracker, and configured to: obtain an association between a plurality of sequences comprising at least one of the multiple discrete states, and a plurality of corresponding system functions of the surgical system, receive an indication of at least one of the discrete states from the function switch, identify a system function based on the indication and the association, receive a head motion from the head tracker, and apply the head motion to control the identified system function of the surgical system.
