HAPTIC INTERFACE PROVIDING IMPROVED CONTROL OF THE HAPTIC SENSATION

摘要

A haptic interface, including: a button moving in a first direction or in a second direction; an interaction element interacting with a magnetorheological fluid with a viscosity that varies in accordance with a magnetic field; a brake including a magnetorheological fluid and a generation system to generate a magnetic field on command; a sensor detecting the current position of the button; a mechanism determining speed of the button; and a controller configured to send orders to the system to generate a magnetic field, the orders being generated according to the current position of the button and the current actuation speed of the button.
