Abstract
This disclosure relates to a vibrotactile mobile device which induces a tactile sense at various positions in an interface method of operating the mobile device so that a user may intuitively interact with the mobile device while seeing a program execution status, and to a method of driving the vibrotactile mobile device. The method of driving the vibrotactile mobile device includes: providing a user interface for inputting a command signal on a screen operated in accordance with a program; calculating a target vibration position and a direction and a speed of a vibration flow with time so as to recognize a trajectory of the command signal displayed on the screen and supply a vibration stimulus corresponding to the trajectory of the command signal; and driving the vibration module by controlling a supply of power to be applied to vibration modules based on the calculated result.
