Abstract
The invention relates to a method for haptic feedback control that comprises a control device for transmitting a haptic feedback to the finger of a user in a movement area of said finger, characterized in that said control method comprises a first step (101) of determining the direction of an elementary movement of said finger and decomposing the elementary movement into components along said first and second driving directions (D1, D2), and a second step (102) of independently driving said first actuator (7a) and second actuator (7b) based on the components of the elementary movement (dU) in order to drive said plate (3) in translation so that the result of the vibratory effect generated by said actuators (7a, 7b) can be felt by said finger in a direction (dR) substantially perpendicular to and coplanar with the direction of said elementary movement (dU).
