Command input method using motion recognition device

A method for inputting command using a motion recognition device is provided to simplify a structure of a command input system by recognizing the same 3D(Dimensional) motion as the different command according to an initial pose of an input device and facilitate implementation of the motion recognition device by using the different motion recognition device according to each initial pose. The initial pose is determined when motion is generated in the motion recognition device(S200). If the motion of the motion recognition device is finished, a pattern of the motion is determined(S400). The command is determined from the determined initial pose and motion pattern(S500). The motion of the motion recognition device is monitored and recorded.
