1. A remote control apparatus of an audio video navigation (AVN) system, the remote control apparatus comprising:
- a stylus pen; and
a central processing unit (CPU) configured to, in response to a remote control function of remotely controlling the AVN system by using the stylus pen according to a user'"'"'s manipulation being set, recognize a position of the stylus pen to set the recognized position as a start point of the stylus pen, set a central point and a help point on a basis of information acquired according to the position of the stylus pen being moved from the start point, generate a virtual touch panel to be used for remote control on a basis of the central point and the help point by connecting the central point and the help point to generate a width direction axis of the virtual touch panel, and measuring an angle between a horizontal axis of the central point and the width direction axis, and remotely control the AVN system according to the user'"'"'s input using the generated virtual touch panel.

9. A remote control method of an audio video navigation (AVN) system, the remote control method comprising:
-
in response to a remote control function of remotely controlling the AVN system by using a stylus pen according to a user'"'"'s manipulation is set, receiving an ultrasonic signal transmitted from the stylus pen through an ultrasonic receiver equipped in the AVN system, and recognizing a position of the stylus pen on a basis of the received ultrasonic signal to set the recognized position of the stylus pen as a start point; calculating a movement position of the stylus pen on a basis of information acquired according to the position of the stylus pen being moved from the start point to set a central point and a help point; generating a virtual touch panel to be used for remote control on a basis of the central point and the help point by connecting the central point and the help point to generate a width direction axis of the virtual touch panel, and measuring an angle between a horizontal axis of the central point and the width direction axis; and remotely controlling the AVN system according to the user'"'"'s input using the generated virtual touch panel. - View Dependent Claims (10, 11, 12, 13)
