Apparatus and Method for Vibrotactile Mobile Device
First Claim
1. A vibrotactile mobile device which supplies a tactile sense to a user by executing a program, comprising:
- a screen which visually displays an execution status of the program;
a plurality of vibration modules which vibrate with a multi-level vibration strength to correspond to the information shown on the screen;
a vibration contact plate which is disposed outside the vibration modules and delivers the vibration generated by the vibration modules to the user; and
a plurality of vibration isolating links which are connected to the vibration modules between the screen and the vibration modules and isolate the vibration generated by the vibration modules.

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.
