Claim Text:
1. A gesture recognizing and controlling method, comprising: capturing a pending image having depth information, wherein the pending image comprises a human form image; analyzing the pending image first by adopting a Blob detection thereby determining a number of connected area in the pending image; analyzing a first barycenter position of a first connected area and a second barycenter position of a second connected area in the pending image when the number of connected area is two; and outputting another controlling signal correspondingly according to a variation of a barycenters-connection length between the first barycenter position and the second barycenter position; analyzing the human form image to obtain hand skeleton information having a first skeleton and a second skeleton, wherein the first skeleton and the second skeleton respectively corresponding to a left hand and a right hand of the human form image; determining whether an intersection point exists between the first skeleton and the second skeleton; determining whether an included angle formed by the first skeleton and the second skeleton is within a first predetermined angle range if the intersection point exists, wherein the intersection point segments the first skeleton into a first segment and a second segment, and the intersection point segments the second skeleton into a third segment and a fourth segment; outputting a controlling signal when the included angle is within the first predetermined angle range; calculating a first ratio between the first segment and the second segment, and calculating a second ratio between the third segment and the fourth segment; and outputting a controlling signal based on the first ratio and the second ratio.
