TOUCH SENSITIVE INTERFACE DEVICE

摘要

PURPOSE: A touch sensitive interface device is provided to vibrate a touch screen unit in direction which is parallel with one side thereof thereby providing operation feeling which changes tactility of touch area of a user. CONSTITUTION: A touch sensing interface device(1000) comprises touch screen unit(110), a driving unit(120) and a control unit(140). In order to change tactility of surface of the touch screen, the driving unit vibrates the touch screen unit in direction which is parallel with one side of the touch screen. A piezoelectric device is used to the driving unit. The piezoelectric device is formed at bar shape. The piezoelectric device is combined in one side of the touch screen unit. The control unit controls operation frequency of the driving unit.
