Abstract
Provided is a method of providing information from a first device to a second device. The method includes: 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. 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. 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. The operator includes at least one tactile sensation provider, that contacts the user of the second device, including polarizable or piezoelectric particles distributed in a matrix.
