<p>PURPOSE: An input feedback method at a touch screen and an apparatus using the same are provided to enable a user to feel various feedbacks for input, thereby providing the user a sensitive interface. CONSTITUTION: A current supply unit supplies currents to a coil(120) arranged in a touch screen(110). A control unit(140) offers feedback by using magnetic force formed by supplying the currents to the coil. If an object is contacted to the touch screen, the control unit generates repulsive power in the coil.</p> |
