ABSTRACT:
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.
