Method of supplying tactile information

A method of providing information from a first device to a second device, the method comprising:

• receiving message information by the second device, the message information comprising a text, a geometric figure, or a symbol that is input into the first device;
• transforming the message information into a tactile signal;
• and
• actuating an operator to provide tactile information according to the tactile signal,
• wherein the operator includes at least one cell and provides the tactile information in the form of handwriting or vibration to a user of the second device, by operating the at least one cell sequentially,
• wherein the operator provides the tactile information by sequentially or simultaneously applying/removing an external electric field to/from each of the cells according to the tactile signal,
• wherein the operator includes at least one tactile sensation provider, that contacts the user of the second device, comprising polarizable or piezoelectric particles distributed in a matrix, and
• wherein the tactile sensation provider maintains a first shape when not influenced by the external electric field, and wherein the tactile sensation provider maintains a second shape when influenced by the external electric field.
