Systems and methods for entering and exiting a teleoperational state

A method for operating a teleoperational system including a teleoperational manipulator and an operator controller, the method comprising:

• determining whether a head portion of an operator is directed toward or away from a display region of a display device based on at least one marker on the operator, wherein the at least one marker remains substantially fixed relative to the head portion of the operator during a movement of the head portion;
• and
• based on a determination that the head portion is directed away from the display region for at least a threshold period of time, enter a standby mode such that movement of the operator controller does not provide corresponding movement to the teleoperational manipulator.

A non-transitory machine-readable medium comprising a plurality of machine-readable instructions which when executed by one or more processors associated with a medical device are adapted to cause the one or more processors to perform a method comprising:

• determining whether a head portion of an operator is directed toward or away from a display region of a display device based on at least one marker on the operator, wherein the at least one marker remains substantially fixed relative to the head portion of the operator during a movement of the head portion;
• and
• based on a determination that the head portion is directed away from the display region for at least a threshold period of time, enter a standby mode such that the movement of an operator controller does not provide corresponding movement to a teleoperational manipulator.
