Abstract: Systems and methods of providing a haptic barrier for an instrument include a computer-assisted device. The computer-assisted device includes a grip input control, a repositionable arm configured to support an instrument, and one or more processors. The one or more processors are configured to detect a position of the grip input control in a first direction of a degree of freedom having In a first region, a second region, and a third region between the first and second regions; in response to determining that the detected position is in the first region, operate the instrument according to a first mode; in response to determining that the detected position is in the third region, provide a haptic barrier to resist movement of the grip input control through the third region; and in response to determining that the detected position is in the second region, operate the instrument according to a second mode.

Abstract: Techniques for controlling a computer-assisted device based on a geometric parameter representative of a geometric relationship of an operator and a display unit include the following. The computer-assisted device comprises a repositionable structure system configured to support a display unit that displays an image viewable by an operator; an actuator system physically coupled to the repositionable structure system; a sensor system configured to capture sensor data associated with a portion of a head of the operator; and a control system. The control system is configured to: determine, based on sensor data, a geometric parameter of the portion of the head relative to a portion of the computer-assisted device, determine a commanded motion based on the geometric parameter and a target parameter, and command the actuator system to move the repositionable structure based on the commanded motion.
