Abstract: The invention relates to a haptic interface comprising a substrate (2), a plate (4) comprising a surface (6) for interaction with one or more fingers of a user, and actuators (A1) capable of applying a vibration to said plate (4), and a control module (MC) for controlling said actuator,—said plate (4) being in the shape of a strip extending along a first direction (X) and delimited transversely to the first direction by two lateral edges (10), said lateral edges (10) being supported by said substrate (6),—said control module (MC) being configured to generate control signals to said actuator (A1) at first frequencies lower than the cut-off frequency of the first propagation mode of said plate, so that the actuator (A1) generates evanescent waves in the plate (4).
