PURPOSE: A user input interface device of a portable terminal and a method thereof are provided to implement intuitive input such as mouse input by generating a pointer of the portable terminal through marker recognition and executing functions of the portable terminal based on the same. CONSTITUTION: A memory(210) stores information about patterns of markers. If the marker is recognized in the outside of a portable terminal, a marker recognizing unit(220) displays a pointer on a display unit of the portable terminal corresponding to a recognized position of the marker. The marker recognizing unit moves the pointer on the display unit according to the movement of the marker and recognizes a pattern change of the marker. An operation unit(230) operates functions of the portable terminal according to the pattern change of the marker.
