A method for a tactile presentation of perceivable content. The method comprises receiving a data representing perceivable content, selecting a plurality of electric currents according to the data, each the electric current is associated with at least one of a plurality of regions of a solution having a plurality of macromolecules, and changing a level of acidity (pH) of at least one of the plurality of regions by applying a respective the electric current thereto. A proton concentration in the plurality of regions tactilely presents the perceivable content. |
