METHOD OF GENERATING KEY CODE IN COORDINATE RECOGNITION DEVICE AND VIDEO DEVICE CONTROLLER USING THE SAME

摘要

A video device controller and method for generating a key code enable key code generation by a single instance of manipulation of the controller by a user, obviating repetitive keypad manipulation and thereby facilitating controller operation. The video device controller includes a touch pad (110), a coordinate recognition unit (120) for recognizing coordinate values corresponding to a touch trajectory executed with respect to the touch pad (110), a key signal input unit (120), having a plurality of keys, for generating a key signal according to a user selection of at least one of the keys; a system controller (140) for calculating values of at least one 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 the key signal, the movement command signal shifting an object displayed on the video device; and a key code generator (150) for generating a key code corresponding to the movement command signal. The touch pad (110) is preferably imparted with a predetermined pattern enabling a touch trajectory to be recognized in a simple manner.
