Interface apparatus for generating control command by touch and motion, interface system including the interface apparatus, and interface method using the same

PURPOSE: An interface apparatus for generating a control command by touch and motion, an interface system including the interface apparatus, and an interface method using the same are provided to recognize the intention of an interface operation through a motion sensor. CONSTITUTION: An interface device(100) includes a multimedia function block(110), a touch screen(120), a motion sensor(130) and a control unit(140). The multimedia function block displays a screen depending on a user interface control operation, and the touch screen senses the touch.
