| 摘要 | A haptic interface, including: a button which can be rotated by a user; an interaction element interacting with a magnetorheological fluid, secured to the button; a mechanism measuring a current position of the button; a brake including a magnetorheological fluid and a generation system to generate a magnetic field in the fluid; a controller configured to generate orders for the system to generate a magnetic fluid to modify a value of the magnetic field; and a mechanism to detect torque exerted by a user on the button to know direction of the torque and whether the torque is greater than a given value for a given direction, the controller controlling generation of a magnetic field based on obtained information about the torque at least when the button indicates zero or low speed. | ||||||
