A method and apparatus for generating a key code in a coordinate recognition device (video device controller 120) enable key code generation by a single instance of manipulation of a controller (140) by a user, obviating repetitive keypad manipulation and thereby facilitating controller operation. A coordinate recognition (120) device is provided with a touch pad (110) having a touch pattern of a predetermined shape, enabling a touch trajectory to be recognized in a simple manner. The apparatus includes a touch pad (110) having a predetermined touch pattern; a coordinate recognition unit (120) for recognizing coordinate values corresponding to a touch trajectory executed with respect to the touch pad (110), a controller (140) for calculating values of a direction, speed, and distance of the touch trajectory using the recognized coordinate values and for outputting a movement command signal based on the calculated values; and a key code generator (150) for generating a key code corresponding to the movement command signal. The method includes steps of recognizing coordinate values corresponding to a touch trajectory executed with respect to a touch pad (110) having a predetermined touch pattern; calculating a direction, speed, and distance of the touch trajectory using the recognized coordinate values; and generating a movement command signal corresponding to the calculated values, the generated movement command signal corresponding to a specific key code.
