A computer system configured to be communicably coupled to a surgical device and a camera, the computer system comprising: a processor; and a memory coupled to the processor, the memory storing instructions that, when executed by the processor, cause the computer system to: receive perioperative data from the surgical device; determine a surgical context based at least in part on the perioperative data, the surgical context comprising a type of a surgical procedure being performed or a type of tissue that is being operated on in a surgical procedure; receive an image of a surgical staff member performing the surgical procedure via the camera; determine a physical characteristic of the surgical staff member from the image, wherein the physical characteristic comprises the position, orientation, angle, or rotation of a body part of the surgical staff member; retrieve a baseline physical characteristic corresponding to the surgical context, wherein the baseline physical characteristic is established by a sampled population or pre-programmed into the computer system; and determine whether the physical characteristic of the surgical staff member deviates from the baseline physical characteristic. a processor; and a memory coupled to the processor, the memory storing instructions that, when executed by the processor, cause the computer system to: receive perioperative data from the surgical device; determine a surgical context based at least in part on the perioperative data, the surgical context comprising a type of a surgical procedure being performed or a type of tissue that is being operated on in a surgical procedure; receive an image of a surgical staff member performing the surgical procedure via the camera; determine a physical characteristic of the surgical staff member from the image, wherein the physical characteristic comprises the position, orientation, angle, or rotation of a body part of the surgical staff member; retrieve a baseline physical characteristic corresponding to the surgical context, wherein the baseline physical characteristic is established by a sampled population or pre-programmed into the computer system; and determine whether the physical characteristic of the surgical staff member deviates from the baseline physical characteristic. receive perioperative data from the surgical device; determine a surgical context based at least in part on the perioperative data, the surgical context comprising a type of a surgical procedure being performed or a type of tissue that is being operated on in a surgical procedure; receive an image of a surgical staff member performing the surgical procedure via the camera; determine a physical characteristic of the surgical staff member from the image, wherein the physical characteristic comprises the position, orientation, angle, or rotation of a body part of the surgical staff member; retrieve a baseline physical characteristic corresponding to the surgical context, wherein the baseline physical characteristic is established by a sampled population or pre-programmed into the computer system; and determine whether the physical characteristic of the surgical staff member deviates from the baseline physical characteristic. <EOS>
