Method of generating key code in coordinate recognition device and video device controller using the same

A controller of a video device, comprising:

• a touch pad having a predetermined touch pattern;
• at least one input key for selecting a set of functions of the video device;
• a coordinate recognition unit for recognizing coordinate values corresponding to a touch trajectory executed with respect to said touch pad;
• a system controller for
• generating, in response to a user operation of the at least one input key, an OSD command signal for displaying an OSD keypad having a set of menu items corresponding to the selected set of the video device functions, the OSD keypad being configured according to the predetermined touch pattern of said touch pad,
• calculating values of at least one of a direction, speed, and distance of the touch trajectory using the recognized coordinate values, and
• outputting a movement command signal based on the calculated values and the key signal, the movement command signal shifting an object among the OSD menu items displayed on the video device;
• and
• a key code generator for firstly generating a key code corresponding to the OSD command signal and for secondly generating a key code corresponding to the movement command signal.

A method of generating a key code in a video device controller including a touch pad having a predetermined touch pattern and at least one hotkey corresponding to a set of functions of a video device, the method comprising:

• recognizing coordinate values corresponding to a touch trajectory executed with respect to the touch pad;
• generating, in response to a user operation of the at least one hotkey, an OSD command signal for displaying an OSD keypad having a set of menu items corresponding to the set of the video device functions, the OSD keypad being configured according to the predetermined touch pattern of the touch pad;
• calculating values of at least one of a direction, speed, and distance of the touch trajectory using the recognized coordinate values;
• outputting a movement command signal based on the calculated values and the key signal, the movement command signal shifting an object among the OSD menu items displayed on the video device;
• and
• respectively generating a key code corresponding to the OSD command signal and a key code corresponding to the movement command signal.
