Abstract:
1. A gesture recognition device mounting on a processing unit, recognizing a gesture of a human hand in a free space through a moving image, and causing said processing unit to execute a predetermined operation corresponding to the recognized gesture, said gesture recognition device comprising: a palm centroid determining unit for determining a centroid of a palm of a hand; a palm area determining unit for determining the area of the palm of the hand; a finger length determining unit for calculating length between the centroid of the palm and fingertips; a finger angle determining unit for calculating angles formed by lines connecting the centroid and the fingertips; and a gesture identifying unit for identifying a gesture from a combination of a variation of the centroid of the palm, a variation of the area of the palm, and a variation of the angles formed by lines connecting the centroid and the fingertip; said gesture identifying unit determining the palm is rotated when the angle formed by lines connecting the centroid and the fingertips is varied.
