Abstract: A gesture recognizing and controlling method and device thereof are provided. The gesture recognizing and controlling method includes the following steps. First, a pending image having depth information is captured, in which the pending image includes a human form image. The human form image is analyzed so as to obtain hand skeleton information having a first skeleton and a second skeleton. It is determined whether the first skeleton and the second skeleton have an intersection point. If yes, it is determined whether an included angle formed by the first skeleton and the second skeleton is within a predetermined angle range. When the included angle is within the predetermined angle range, a controlling signal is output accordingly.

Abstract: The present invention discloses a display system. The display system includes a display device, an image recognition device and a communication device. The display device is arranged to display a plurality of frames of a video stream. The image recognition device is arranged to compare the current frame with the previous frame displayed by the display device to define at least one stationary block and determine whether the stationary block has a phone number or an Internet address, wherein the current frame is the frame displayed by the display device currently, and the current frame is displayed next to the previous frame. The communication device is arranged to make a phone call to the phone number or connect to the web address via the Internet.
