An access control method is performed on an equipment item linked to elements for rendering at least one haptic signal on a haptic rendering surface, wherein the haptic signal is a touch-discernible texture. The method includes, after an access request has been obtained: ordering rendering of a haptic signal; obtaining information on detection of a gesture of response to the signal; of validating the gesture of response when the gesture detected corresponds to a gesture previously associated with the haptic signal rendered; and authorizing access following the validation of the gesture.
