Abstract
A method for generating haptic sensations from a haptic interface including: a rotatable button; an element for interacting with a fluid with a viscosity that varies as a function of an exterior stimulus, the element for interacting with the fluid moving with the button; a fluid with an apparent viscosity that varies as a function of a magnetic field and that surrounds the element for interacting with the fluid; and a system for generating a magnetic field on command in the fluid. The method includes: evaluating a current position of the button; determining a direction of rotation of the button; altering the value of the current position when the current position is in a haptic stop zone and the direction of rotation of the button is associated with the haptic stop, and as long as the direction of rotation of the button is not modified.
