Gesture recognition device, method, program, and computer-readable medium upon which program is stored

Abstract

The present invention provides a gesture recognition device which can accurately recognize a user's gesture in a free space with a simple configuration, and which is mounted on a processing unit and which causes the processing unit to execute an operation corresponding to the recognized gesture. The gesture recognition device (1000) comprises a palm centroid determining unit (30) for determining centroid of a palm, a palm area determining unit (40) for determining the area of a palm, a finger length/angle determining unit (50) for calculating length of finger by obtaining the length between the centroid and the fingertips and for calculating the angles formed by lines connecting the centroid and the fingertips, and a gesture identifying unit (60) for identifying the gesture by the combination of the variation of the centroid of the palm, the change of the palm area, the change of length between the centroid and the fingertips and the change of angles formed by the lines connecting the centroid and the fingertips.
