As a solution to the lack of compactness and simplicity often encountered in haptic interfaces, we propose a device based on friction coefficient control principle. This device includes polarised piezoceramics well adjusted and glued to a 64x38x3 mm copper-beryllium plate supported by four legs. Then, properly energised around a resonant frequency, with legs at antinodes, a stationary wave is created in the plate. Variable friction forces between the legs and the plane substrate are created by the control of the wave amplitude, according to electro-active lubrication. So the user obtains force feedback by holding the plate, and moving it on a plane substrate, as he could do with a mouse interface. Preliminary psychophysical evaluation trends to assess the validity of the device as a force feedback interface.
