Abstract: A command input method makes use of a three-dimensional motion recognition device embodied with an inertia system and is particularly directed to extend the total number of inputable commands using initial posture information as well as movement pattern of a motion recognition device. The command input method includes the steps of: determining initial posture at start point when movement of the motion recognition device is generated; determining a pattern of the movement at the end of the movement; and deciding a command from the determined initial posture and the movement pattern. Since the three-dimensional spatial motion can be further differentiated into different commands by the initial posture of the input device, the command input system can be simplified in structure with less number of recognizable motions.
