Interaction between user-interface and master controller

1. A method to control actuation of a click event by a hand-actuated selector moveably mounted to a mount structure, comprising:

using one or more sensors to sense amount of displacement distance of the hand-actuated selector from a neutral position;

in response to the hand-actuated sensor at a displacement distance less than a first threshold distance from the neutral position, controlling one or more motors according to a first control state to impart a maintaining force;

in response to sensing the hand-actuated sensor at a displacement distance between a first threshold distance from the neutral position neutral position and a second threshold distance from the neutral position, controlling one or more motors according to a second control state to impart 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;

in response to sensing the hand-actuated sensor has met the second threshold distance from the neutral position,

imparting a click event signal to cause an occurrence of the click event at a display system, and

controlling the one or more motors according to a third control state to reduce magnitude of the haptic force imparted to the hand-actuated selector to a reduced magnitude that is less than a maximum magnitude of the haptic force imparted during the second control state, wherein the haptic force decreases in magnitude to the reduced magnitude as a function of increasing displacement of the hand-actuated selector from the neutral displacement position.

2. The method of claim 1 ,

wherein the maintaining force is zero.

3. The method of claim 1 ,

4. The method of claim 1 further including:

using the one or more motors to cause the hand-actuated selector to move to the neutral position.

5. The method of claim 1 further including:

6. The method of claim 1 further including:

using a stop surface to stop motion of the hand-actuated selector.

7. The method of claim 1 further including:

using a stop surface, positioned to impart a reactive force to the hand-actuated selector to stop further displacement of the hand-actuated selector when the hand-actuated selector reaches the third threshold displacement distance from the neutral position.

8. An apparatus to control actuation of a click event by a hand-actuated selector moveably mounted to a mount structure, comprising:

one or more sensors configured to sense position of the hand-actuated selector;

one or more motors configured to impart haptic force to the hand-actuated selector;

processing circuitry; and

a memory system storing instructions which, when executed by the processing circuitry, cause the processing circuitry to perform operations comprising:

using the one or more sensors to sense amount of displacement of the hand-actuated selector from a neutral position;

in response to the hand-actuated sensor at a displacement distance less than a first threshold distance from the neutral position, controlling one or more motors according to a first control state to impart a maintaining force;

in response to sensing the hand-actuated sensor at a displacement distance between a first threshold distance from a neutral position neutral position and a second threshold distance from the neutral position, controlling one or more motors according to a second control state to impart a haptic force to the hand-actuated selector that increases in magnitude as a function of increasing displacement of the hand-actuated selector from the neutral displacement position;

in response to sensing the hand-actuated sensor has met the second threshold distance from the neutral position,

imparting a click event signal to cause an occurrence of the click event at a display system, and

controlling the one or more motors according to a third control state to reduce magnitude of the haptic force imparted to the hand-actuated selector to a reduced magnitude that is less than a maximum magnitude of the haptic force imparted during the second control state, wherein the haptic force decreases in magnitude to the reduced magnitude as a function of increasing displacement of the hand-actuated selector from the neutral displacement position.

9. The apparatus of claim 8 ,

wherein the act of controlling the control the one or more motors according to the third control state occurs after the act of imparting the click event signal.

12. The apparatus of claim 8 ,

wherein controlling the one or more motors according to the third control state includes controlling the one or more motors to impart a haptic force to the hand-actuated selector that decreases instantaneously to the reduced magnitude.

13. The apparatus of claim 8 further including:

instructions that, when executed cause the processor to perform operations comprising:

controlling the one or more motors to cause the hand-actuated selector to move to the neutral position.
