The invention relates to a tactile device provided with a number of fluid
elements (1) containing an electrically conducting fluid (3, 4). The
fluid level in each element is movable by actuator means (V, 6) applying
a electric power to said fluid elements. Each fluid element is in contact
with the fluid for perception of the fluid level by a user. The fluid
elements comprise capillary tubes (2) in which the fluid level is movable
as a result of electro-capillary pressure.
