Abstract: A method is provided to control actuation of a click event by a hand-actuated selector moveably mounted to a mount structure, comprising: in a first control state, imparting a maintaining force to the hand-actuated selector; in a second control state, imparting a haptic force to the hand-actuated selector that increases as a function of increasing displacement of the hand-actuated selector from the neutral displacement position; imparting a click event signal to cause an occurrence of the click event at a display system, in a third control state, imparting a haptic force to the hand-actuated selector that decreases in magnitude to a reduced magnitude.

Abstract: Techniques for adjusting a display unit (206) of a viewing system include repositionable structure (204) configured to support a display unit, first and second hand-input sensors (240) configured to receive inputs from the operator; and a control unit. The display unit is configured to display images viewable by an operator. The control unit is configured to receive a first input from the first hand-input sensor, receive a second input from the second hand-input sensor, and, in response to satisfaction of a criteria set including, determine a commanded motion based on the first and second inputs and command an actuator to move the repositionable structure based on the commanded motion. The criteria set includes that a first magnitude of the first input and a second magnitude of the second input are greater than a threshold.

Abstract: Techniques for adjusting a headrest of a computer-assisted system include the following. The computer-assisted system includes a display unit configured to display images viewable by an operator, a headrest coupled to the display unit, the headrest configured to be contacted by a head of the operator, an actuator operable to move the headrest relative to the display unit, a head-input sensor, and a control unit communicably coupled to the actuator and the head-input sensor. The control unit is configured to: determine head data based on sensor data acquired by the head-input sensor, determine a commanded motion based on at least the head data, a baseline, and a damping, and command the actuator to move the headrest based on the commanded motion.
